The present systems and processes relate generally to the field of valve systems, and more particularly relates to the use of petals in the field of dilating disk valves for pressure regulation and the control of fluids in machines.
In fluid control systems, valves are vital components for facilitating restricting and allowing fluid to flow through a particular passageway. Commonly, valves include a closing obturator to restrict fluid flow through an aperture. The closing obturator can include one or more component, such as a petal, that moves into the path of the fluid flow to block fluid movement through the aperture. In this way, the petals combined with mechanical components of a valve are used to control fluid movement through passageways. In a dilating disk valve, the petals are designed to a precise geometric shape, and created as one solid piece of metal with a sealing surface from another material. This geometric shape may create areas of high fluid velocity under certain process conditions. In particular, when corrosive or high temperature fluids pass over the petals during opening and closing, if the velocity of the fluid is high enough, the sealing surface of these petals may erode or melt away.
Therefore, a geometric solution is needed, incorporating a sophisticated understanding of fluid dynamics, for a system or method that creates an adequate seal while maintaining structural integrity in difficult environments.
Briefly described, and according to one embodiment, aspects of the present disclosure generally relate to systems and methods for sealing a passageway in a fluid management system. In various embodiments, the disclosed system includes a dilating disk valve. The dilating disk valve can be a mechanically and/or electronically operated valve system used to reduce and/or completely stop flow of fluids in a piping system. The dilating disk valve can include obturator elements (referred to herein as “petals”). The dilating disk valve can include a valve body, a gear mechanism, and at least three or more petals.
In a three petal dilating disk valve system, the petals are attached to the valve body and the gear mechanism. By activating the gear mechanism, the petals can rotate about the location they are attached on the valve body. As the petals rotate about the location they are attached on the valve body, the petals meet at the center of the dilating disk valve. Each petal can include a tongue and a groove. As the petals make contact to create a seal, the tongue of each petal connects with the groove of each adjacent petal. For example, the tongue of the first petal connects with the groove of the second petal; the tongue of the second petal connects with the groove of the third petal; and the tongue of the third petal connects with the groove of the first petal. As the petals make full contact at the center, the petals block any fluid from flowing through the dilating disk valve.
The petal can include a seal insert and a body. The body can be constructed from a metallic material (e.g., metal). Example materials for the body can include, but are not limited to, carbon steel, stainless steel, various metal alloys, and titanium. The petal body material of the petal is selected to withstand high temperature fluids, highly acidic fluids, highly basic fluids, and/or any other extreme fluid condition. The body provides structural integrity to the petal. The insert can be placed into the body of the petal. The insert can be designed to accept the tongue of the body of any particular adjacent petal. The insert can be made of Polytetrafluoroethylene (PTFE) materials. Creating the insert from PTFE can increase the sealing capabilities of the petal.

For the purpose of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will, nevertheless, be understood that no limitation of the scope of the disclosure is thereby intended; any alterations and further modifications of the described or illustrated embodiments, and any further applications of the principles of the disclosure as illustrated therein are contemplated as would normally occur to one skilled in the art to which the disclosure relates. All limitations of scope should be determined in accordance with and as expressed in the claims.
Aspects of the present disclosure generally relate to systems and methods for flow management of a substance through a particular passageway. In various embodiments, the disclosed system combines a metal portion and a sealing portion (e.g., Polytetrafluoroethylene (PTFE)) with a cutaway design for a valve petal used for flow management. In some embodiments, the valve petal can be referred to as an obturator. An obturator can be a device that manages the flow of a substance through a passageway or aperture. In particular embodiments, the metal and PTFE valve petals include a metallic body and a sealing insert (e.g., an insert made at least in part from PTFE or other sealing material).
The combination of the metallic body with the sealing insert can allow for greater sealing capabilities via the sealing insert while maintaining structural integrity via the metal body for extreme (e.g. high temperature, high acidity, and/or highly corrosive) fluid management. The sealing insert can be suseptible to enhanced wear (e.g., erosion, corrosion, melting, etc.). The cutaway shape of the sealing insert positions metal material in most areas most succeptible to wear during use. By using the sealing insert, the valve petals can form an effective seal due to the PTFE's enhanced elasticity. The sealing material have a portion facing the source of fluid omitted/replaced by metal from the metal body to avoid excess wear on the sealing material under the turbulant forces on the petals caused when the valve is closing. The sealing material can facilitate a more effective sealing surface at seams between various metal petals. The metal body can provide structural integrity and resistance to erosion when used with extreme fluid conditions. The metallic body can have a protruding edge. The size of the protruding edge can substantially match the size of the cutaway portion of the sealing insert. The larger the size of the protruding portion of the metallic body, the less the sealing material is exposed to the extreme conditions.
The sealing insert can be appended to or affixed into the metallic body to create a single petal component. In at least one embodiment, the sealing insert can append to the metallic body by any adequate appending technique. Some adequate appending techniques can include, but are not limited to, welding, gluing, and riveting. In one or more embodiments, the sealing insert is held into place inside the metallic body using one or more pins. In one embodiment, the one or more pins includes two pins. The pins can anchor the sealing insert to the metallic body to secure the two components together. In one embodiment, the pins can be welded in place to hold the sealing insert. In some embodiments, the sealing insert can be pressure fit into a channel. The pins can be used to secure the pressure fitted sealing insert into the channel. In one or more embodiments, the pinning technique is paired with an appending technique or one or more other securing techniques to create a firm hold between sealing insert and the metallic body.
The metallic body can include a tongue protrusion that can fit into a groove of an adjacent petal. The metallic body can include a hinge aperture. The metallic body can be coupled to a valve body at the hinge aperture and pivot about the hinge aperture. The metallic body can include a control aperture. The metallic body can be affixed to a control mechanism at the control aperture. The control mechanism can move the metallic body between a first position and a second position via the control aperture. In some embodiments, the first position can be an open position that freely allows fluid flow through a fluid aperture. In some embodiments, the second position can be a closed position that prevents fluid from flying through the fluid aperture. The metallic body can be connected to a gear mechanism at the control aperture, and the metallic body can connect to a hinge pin at the hinge aperture. The gear mechanism can rotate the valve petal about the hinge pin into an opened or closed state. In some embodiments, the tongue is inserted into a groove in the insert of an adjacent valve petal during a closing procedure. In some embodiments, the tongue presses up against the adjacent valve's sealing insert to create a seal. In an at least two petal system, the petals can perform the closing procedure to facilitate sealing the valve. In certain embodiments, sealing the valve will stop the flow of substances through the particular passageway.
The valve can include at least two petals. The valve can include a rotating mechanism (e.g., a gear mechanism) that operatively opens or closes the valve petals. In some embodiments, the valve includes three petals, where each petal forms one-third of the closed valve surface. In particular embodiments, the valve can connect to a passageway system to control the flow of a particular substance. For example, the valve is connected between two portions of a pipe to control the flow of fluid, such as, for example, the flow of liquid nitrogen in a factory.
Referring now to the figures, for the purposes of example and explanation of the fundamental processes and components of the disclosed systems and processes, reference is made to
The petal 100 can include an insert 101 and a body 102. The insert 101 can include, but is not limited to, a full inner groove protrusion 106, a rear anchor 108, a cutaway inner groove protrusion 109, a groove 112, and a recessed surface 130. The body 102 can include, but is not limited to, one or more outer groove protrusions 103A and 103B, an upper surface 104, a lower surface 105, a curved surface 107, a groove channel 111, one or more apertures 118A and 118B, a tongue protrusion 115, a control aperture 121, a hinge aperture 124, and a tongue recessed portion 127. The recessed surface 130 can occupy a lowest, bottom, or recessed portion of the groove 112. The recessed surface 130 can be referred to as a central surface. The cutaway inner groove protrusion 109 can be referred to as a first side wall and/or a partial side wall. The full inner groove protrusion 106 can be referred to as a second side wall.
In some embodiments, a dilating disk valve 800 (see
The dilating disk valve 800 can be configured to allow fluid to flow when in an open position. The dilating disk valve 800 can be configured to restrict fluid from flowing when in a closed positon. In some embodiments, the dilating disk valve 800 can be intended to allow fluid to flow in only one direction. As an example, the dilating disk valve 800 may include petals 100 with the cutaway inner groove protrusion 109 positioned on a first side of the dilating disk valve 800. The fluid can flow in the direction of the cutaway inner groove protrusion 109 on the first side of the dilating disc valve 800 towards the full inner groove protrusions 106 of the petals 100 positioned on a second side of the dilating disk valve 800.
The insert 101 of the petal 100 can be made from a sealing material. The sealing material of the insert 101 can be semi-ridged and/or substantially less ridged than a metallic material of the body 102. In one example, the sealing material includes Polytetrafluoroethylene (PTFE). In particular embodiment, the sealing material can be made from layers of metal and graphite. The layers of metal and graphite can include a graphite and steel layered laminate. In various embodiment, the insert 101 is made of the sealing material to increase the sealing factor of the petals 100 when the dilating disk valve 800 is in the closed position. For example, the groove 112 of the second petal 100 can receive the tongue protrusion 115 of the first petal 100. Continuing this example, the tongue protrusion 115 of the first petal 100 and the groove 112 of the second petal 100 can form a greater seal when the ridged material of the tongue protrusion 115 makes contact and presses into the semi-ridged material of the groove 112 of the second petal 100. The insert 101 can be manufactures using compression molding, injection molding, rotational molding, extrusion molding, blow molding, and/or any other suitable manufacturing technique. The sealing material of the insert 101 can be a lower density than the metallic material of the body 102.
The body 102 of the petal 100 can be made from a metallic material. In certain embodiments, the metallic material of the body 102 can include, but is not limited to, carbon steel, stainless steel, alloy steels, titanium, a composite material, and/or any other ridged material. The body 102 can be manufactured using injection molding, computer numerical control (CNC) machining, milling, blow molding, and/or any other adequate manufacturing technique. The material of the body 102 can be ridged to increase the structural integrity of the dilating disk valve 800 when in a closed position. The ridged material used for the body 102 can increase the structural integrity of the dilating disk valve 800 when transitioning from the opened to closed position. The metallic material of the body 102 can be substantially more ridged than the sealing material of the insert 101.
The dilating disk valve 800 can rotate the petals 100 about the hinge aperture 124 by applying a force on the control aperture 121. The control aperture 121 can be referred to as a control connection portion and/or a first aperture. The hinge aperture 124 can be referred to as a hinged connection portion and/or a second aperture. The petals 100 can move between a first position corresponding to the dilating disk valve 800 being open (e.g., fluid can pass through the dilating disk valve 800) to a second position corresponding to the dilating disk valve 800 being closed (e.g., fluid is prevented from passing through the dilating disk valve 800). For example, the petal can move from the first position to the second position by pivoting about the hinge aperture 124 based on a movement of the control aperture 121. In some embodiments the petals 100 of the dilating disk valve 800 can move from the closed position to the opened position to facilitate fluid flow. During a transition from the first position to the second position, the petals 100 are forced into the pathway of fluid flowing through the dilating disk valve 800. Once fully closed, the dilating disk valve 800 can substantially reduce the volume of fluid passing through the dilating disk valve 800. For example, in a closed state the dilating disk valve 800 can allow 0 milliliters (ml) of fluid to flow through the dilating disk valve 800 over a minute. For example, in a closed state the dilating disk valve 800 can allow 46 ml of fluid to flow through the dilating disk valve 800 over a minute.
The body 102 can include the outer groove protrusion 103A (also referred to as a partial surface and/or partial ledge). The outer groove protrusion 103A can be positioned toward a first side of the petal 100. In some embodiments, the outer groove protrusion 103A can be in a source direction of intended fluid flow. For example, the fluid first makes contact with the body 102 at the outer groove protrusion 103A. The body 102 can include the outer groove protrusion 103B (also referred to as a full surface and/or full ledge). The outer groove protrusion 103B can be positioned toward a second side of the petal 100. In particular embodiments, the second side is opposite the first side.
The fluid flow can create a greater force than under normal conditions on outer edges 131A-B and an inner edge 133A. The outer edge 131A can extend from the top of the curved surface 107 (e.g., nearest to the rear anchor 108) to the bottom of the curved surface 107 (e.g. nearest to the tongue protrusion 115). The outer edge 131B can extend along the sides of the tongue protrusion 115. The inner edge 133A can extend the length of the outer groove protrusion 103A not in contact with the cutaway inner groove protrusion 109. The outer edges 131A-B can be substantially similar on both sides of the petal 100. In particular embodiments, the outer edges 131A-B and the inner edge 133A of the petals 100 facing the direction of fluid flow into the dilating disk valve 800 can experience heightened forces from the restricted fluid flow. Restricted fluid flow can occur when the dilating disk valve 800 is transitioning from the open position to the closed position or from the closed position to the opened position. Turbulence created by the fluid flowing over the outer edges 131A-B and the inner edge 133A of the petals 100 can produce heightened forces exerted on the outer edges 131A-B and the inner edge 133A of the petals 100.
The sealing material of the insert 101 may be less resistant than the metal material of the body 102 to the heightened forces experienced while closing or opening the dilating disk valve 800. For example, the sealing material may be less resistant than the metallic material especially when the fluid corresponds to a corrosive material such as high temperature fluids, acidic fluids, or basic fluids, etc. The lower resistance of the sealing material of the insert 101 compared to the metallic material of the body 102 can be attributed to its lower rigidity. In some embodiments, the sealing material of the insert 101 may wear away, deform, or deteriorate over time if used along the inner edge 133A of the groove protrusion 103A. For example, the sealing material of the insert 101 may wear away from fluid vapors if positioned on the inner edge 133A. In some embodiments, the sealing material of the insert 101 has a rigidity and resistance to deformation less than the rigidity of the metallic material of the body 102.
The tongue protrusion 115 can be referred to as a first mating surface. The tongue protrusion 115 can be defined by a first edge portion (e.g., an outer edge 131B) along a first section of an outside circumference of the petal 100. The first section of the outside circumference can be referred to as the tongue recessed portion 127. In some embodiments, the outer groove protrusions 103A-B can combine to demarcate a second edge portion. The groove protrusions 103A-B can outline the groove channel 111. The groove protrusions 103A-B can extend along a second section of the outside circumference of the petal 100. For example, the second section of the outside circumference can include a top surface 113. The top surface 113 can extend continuously including the outer groove protrusions 103A-B, the insert 101 and portions of the body 102.
The cutaway inner groove protrusion 109 as compared to the full inner groove protrusion 106 can omit an extended portion of the sealing material. The omitted portion of the cutaway inner groove protrusion 109 can be referred to as a cutaway portion. The cutaway portion can be replaced with the metallic material of the body 102. For example, the out groove protrusion 103A can occupy the space vacated by the cutaway portion of the cutaway inner groove protrusion 109. In some embodiments, the cutaway portion can vary in size. For example, the size of the cutaway portion can be increased to increase the size of the outer groove protrusion 103A. In another example, the size of the cutaway portion can be decreased to decrease the size of the outer groove protrusion 103A. In some embodiments, the outer groove protrusion 103A can completely replace the cutaway inner groove protrusion 109 (see
As used herein, the term “replaced” can be used to mean replaced in a design rather than to indicate that something is physically replaced. For example, the cutaway inner groove protrusion 109 as compared to the full inner groove protrusions 106 can be said to have a portion “replaced” with a metallic material from the body 102 in the design of the petal 100.
The inner edge 133A can correspond to the portion of the petal 100 that experiences the wear during closing over time. The edge of the fluid source side of the petal 100 including the inner edge 133A can experience greater wear during closing than other portions of the petal 100. The metallic material can be selected to withstand the heightened forces experienced during closing without wearing away. By replacing the sealing material in the design of the petal 100 with the metallic material at the cutaway portion, the longevity of the valve can be greatly increased. In some embodiments, the wear on the edge of the petal 100 can be mitigated. For example, using a highly ridged material for the metallic material of the body 102 can prolong the lifespan of the petal 100. Using the cutaway inner groove protrusion 109 rather than a full inner groove protrusions on the fluid source direction side of the petal 100 can increase the longevity of a dilating disk valve 800 by mitigating wear on the petals 100. For example, the dilating disk valve 800 can maintain an adequate seal for a greater period of time by delaying or preventing the sealing material from wearing away. Maintaining an adequate seal can include, but is not limited to, only allowing up to 46 ml of fluid flow through the dilating disk valve 800 in a closed position.
The body 102 can include the upper surface 104, the lower surface 105, and the curved surface 107. In some embodiments, the curved surface 107 divides the upper surface 104 from the lower surface 105. The curved surface 107 can transition the upper surface 104 to the lower surface 105. The curved surface 107 can help facilitate redirecting fluid pushing against the petal 100 in the dilating disk valve 800. For example, as the dilating disk valve 800 transitions from the opened position to the closed position, the curved surface 107 can help redirect fluid as the fluid flows against the closing petals 100.
The insert 101 can provide a sealing surface when the tongue protrusion 115 of the first petal 100 is pressed against the groove 112 of the second adjacent petal 100. The recessed surface 130 can seal against a face 136 of the tongue protrusion 115. In some embodiments, a first side 201B and a second side 201A (see
In some embodiments, the insert 101 can be friction fit into the groove channel 111 formed in the body 102. In particular embodiments, the insert 101 can be affixed to the body 102 via pins 501A-B (see
In at least one embodiment, the cutaway inner groove protrusion 109 can cover a portion of the distance along from the recessed surface 130 outward toward the inner edge 133A. As an example, the entire inner edge 133A can correspond to the second material, while a portion of the way toward the recessed surface 130, the petal 100 can transition to the sealing material. The sealing material can occupy a portion of the sidewall of the groove 112 from an intersection with the recessed surface 130 up partway (e.g., 25% of the way, 50% of the way, 75% of the way, etc.) toward the inner edge 133A.
Referring now to
The petal 100 can include a tongue width 211A and an insert width 212. In various embodiments, the tongue width 211A is equal to or smaller than the insert width 212. By angling the first side 201B and the second side 201A, the tongue width 211A reduces relative to a tongue width 211B at the base of the tongue protrusion 115. By reducing the tongue width 211A relative to the insert width 212 and the tongue width 211B, the tongue protrusion 115 of the first petal 100 can fit into the groove 112 of the second petal 100 during a closing procedure. In an alternative example, if the tongue width 211A is larger than the insert width 212, the tongue protrusion 115 of a first alternative petal cannot fit into the groove 112 of a second alternative petal. In some embodiments, increasing the tongue width 211B relative to the tongue width 211A allows the tongue protrusion 115 to connect with the cutaway inner groove protrusion 109, the full inner groove protrusion 106, and the outer groove protrusion 103A.
The body 102 can include an outer groove width 213 and a cutaway width 214. Depending on the size of the insert 101, the cutaway width 214 can increase or decrease. In some embodiments, the outer groove width 213 and the cutaway width 214 are substantially similar. For example, if the cutaway inner groove protrusion 109 extends the entire length of the insert 101, the outer groove width 213 and the cutaway width 214 can be substantially equal. The body 102 can include a full groove width 215. The full groove width can measure the width of the outer groove protrusion 103B. In various embodiments, the full groove width 215 and the outer groove width 213 can be substantially similar. In some embodiments, the full groove width 215 and the cutaway width 214 can be substantially similar.
The insert 101 can include an insert first width 217 and an insert second width 216. In some embodiments, the insert first width 217 and the insert second width 216 are substantially similar. The insert first width 217 can measure the width of the cutaway inner groove protrusion 109. The insert second width 216 can measure the width of the outer groove protrusion 106.
The insert 101 can include a beveled edge 221. The beveled edge 221 can facilitate a transition between the cutaway inner groove protrusion 109, the full inner groove protrusion 106, and the recessed surface 130. For example, a first beveled edge 221 of the full inner groove protrusion 109 intersects a second beveled edge 221 of the recessed surface 130. Continuing this example, a third beveled edge 221 on the opposite side of the recessed surface 130 can abut the cutaway inner groove protrusion 106. The beveled edge 221 can increase the seal between the first petal 100 and the second petal 100. For example, the tongue protrusion 115 of the first petal 100 can press against the beveled edge 221 and the recessed surface 130 of the second petal 100 to create a greater seal. In some embodiments, the beveled edges 221 extend throughout the groove 112 and the insert 101. For example, beveled edges 221 can connect the recessed surface 130 to the full inner groove protrusion 106.
The groove 112 of the insert 101 can be referred to as a channel. The groove 112 can include the recessed surface 130, the cutaway inner groove protrusion 109, and the full inner groove protrusion 106. The recessed surface 130 can be substantially perpendicular to the cutaway inner groove protrusion 109 and the full inner groove protrusion 106. The cutaway inner groove protrusion 109 can abut the outer groove protrusion 103A and the full inner groove protrusion 106 can abut the outer groove protrusion 103B.

The dilating disk valve 800 can include a controlling arm 801, a controlling pin 802, a hinge pin 803, and an aperture 804. A plurality of controlling arms 801 can connect to the petals 100A-C using the corresponding controlling pin 802. The controlling pin 802 can be an extension of the controlling arm 801 and can insert into the control aperture 121. The controlling pin 802 can exert force onto the petals 100A-C to open or close the dilating disk valve 800. For example, the controlling arm 801 rotates to the right and applies a force onto the petals 100A-C via the controlling pin 802. Continuing this example, as more force is exerted on the petals 100A-C, the petals 100A-C begin to rotate in a clockwise direction. Continuing this example, rotating the petals 100A-C to the right allows the petals 100A-C to close.
The petals 100A-C can rotate around the hinge pin 803. The hinge pin 803 can be inserted into the hinge aperture 124 and can be substantially grounded. In various embodiments, the hinge pin 803 is attached to the valve body of the dilating disk valve 800 to ground the petals 100A-C to a particular location. Grounding the petals 100A-C at the location of the hinge pin 803 can facilitate the petals 100A-C rotating about that location. For example, as a force is exerted by the controlling arm 801 in a clockwise direction, the petals 100A-C are pulled to the right. Continuing this example, the petals 100A-C rotate about the hinge pin 803. Continuing this example, the petals 100A-C continue to rotate until all three petals 100A-C have met at the center of the dilating disk valve 800. On rotating the petals 100A-C with the controlling arm 801, the petals 100A-C can converge to close the dilating disk valve 800. Closing the dilating disk valve 800 can block the aperture 804.

A plurality of controlling bases 901 can attach to the rotating arm 1001. For example, in a three petal 100 system, three controlling bases 901 are fixed to the rotating arm 1001. When closing, the turning device 1002 can rotate clockwise and cause the rotating arm 1001 to rotate clockwise simultaneously. As the rotating arm 1001 rotates clockwise, the plurality of controlling bases 901 can rotate in a clockwise direction. As the controlling bases 901 rotate in a second direction, a force can exert onto the petals 100 via the controlling arms 801. As a counterclockwise force is exerted into the petals 100, the controlling arm 801 can rotate clockwise around the controlling base, and the petals 100 can rotate about the hinge pin 803. In various embodiments, the petals 100 can join at the middle of the dilating disk valve 800 to form a seal.

In a closed state, the controlling arm 801 can be in a substantially perpendicular state relative to the controlling base 901. When the controlling arm 801 is in a perpendicular state relative to the controlling base 901, the petals 100 can rotate to their maximum closed position. A maximum closed position can be defined as a state where all three petals 100 touch at the closing point 1201 and form an appropriate seal. The appropriate seal of the petals 100 in a closed position can be defined by a maximum amount of fluid flow through the aperture 804 (not pictured) per minute. For example, for the appropriate seal, the petals 100 in a closed state can allow up to 46 milliliters (ml) of fluid flow per minute through the aperture 804. In a maximum closed position, the controlling arm 801 can continue to apply closing pressure onto the petals 100 via the controlling pin 802.

At box 1403, the process 1400 can include rotating a gear mechanism. The gear mechanism can include the rotating arm 1001 and the turning device 1002. The turning device 1002 can rotate and apply a pulling or pushing force on the threads 1011. For example, if the turning device 1002 rotates in a counterclockwise direction, the turning device 1002 will apply a force on the threads 1011 to the left. The force produce by the turning device 1002 and applied to the threads 1011 can translate the rotation of the turning device 1002 in one direction into the rotation of the rotating arm 1001 in the same direction. For example, if the turning device 1002 rotates in a clockwise direction, the rotating arm 1001 can will rotate in a clockwise direction.
At box 1406, the process 1400 can include moving a plurality of obturator elements, according to one embodiment of the present disclosure. In various embodiments, as the rotating arm 1001 begins to rotate in a particular direction, the plurality of controlling base 901 follows the same path as the rotating arm 1001. For example, if the rotating arm 1001 rotates clockwise, the plurality of controlling bases rotate clockwise. Each controlling base 901 can connect to the plurality of controlling arms 801. The plurality of petals 100 can connect to the controlling arm 801 and to the plurality of hinge pins 803. As the controlling base 901 rotates, the controlling arm 801 pulls the petals 100 in the direction of rotation. As the petals 100 are pulled by the controlling arm 801, the petals 100 begin to rotate about the fixed hinge pins 803. For example, if the rotating arm 1001 rotates in a clockwise direction, the petals 100 begin to rotate about the hinge pins 803 in a clockwise direction. Continuing this example, the petals 100 begin to approach a closing position as they continue to rotate in a clockwise direction.
At box 1409, the process 1400 includes coupling the tongue protrusion 115 to the groove 112, according to one embodiment of the present disclosure. The face 136 can approach the recessed surface 130 of the insert 101 as the dilating disk valve 800 begins to close. In one or more embodiments, the face 136 presses up against the recessed surface 130. As the face 136 and the recessed surface 130 are pressed together, the petals 100 can form a seal to restrict the flow of particular fluids. For example, as one petal 100 approaches an adjacent petal 100, the face 136 of the first petal 100 can couple to the recessed surface 130 of the second adjacent petal 100 as the dilating disk valve 800 closes.
At box 1412, the process 1400 includes sealing the aperture 804, according to one embodiment of the present disclosure. The rotating arm 1001 can lock into place after the petals 100 couple together. Locking the rotating arm 1001 can facilitate a constant seal between the petals 100. In particular embodiments, the dilating disk valve 800 employs any suitable method for constantly applying pressure onto the petals 100 to maintain a sealed position. In a sealed position, the petals 100 can allow up to 46 ml of fluid flow per minute through the aperture 804.
