The present invention relates to the field of valves in couplings for meters and more particularly to valves in couplings for water meters and gas meters.
Meters for fluids, such as water meters and gas meters, are utilized to determine the volume of fluid being supplied to a residential or commercial structure. The meter is assembled between the water lines or gas lines of the structure and the utility lines of the utility company supplying the water or gas. The meter then measures and records the volume of fluid flowing through the meter. The volume of the fluid is then read off of the meter either visually or remotely for processing.
Typically, a manual shut off valve is connected to the meter so that the provider or the party receiving the supply of water of gas can shut off the supply for any reason, such as stopping service or repairs. The manual shut off valve often requires a specialized tool or key to manually open or close the shut off valve. Further, the manual shut off valve often becomes covered in dirt due to its location in the ground and must be dug up to locate and operate. As the shut off valve must be manually operated, either the provider must send someone or the party receiving the service must be present to operate the shut off valve. Thus, problems may not be addressed in a timely fashion leading to water damage or unintended service interruptions. As well, there are additional problems in affixing new shut off valves (or other valves) to meters that are already installed in the ground.
Embodiments of the present invention address deficiencies of the art in respect to valves in meter couplings and provide a novel and non-obvious apparatus for a hinge nut for a meter coupling. In an embodiment of the invention, the hinge nut includes at least two portions attached to each other by a hinge pin adjacent a distal end of each portion and the two portions are configured to be moved between an open position and a closed position. In the closed position, the hinge nut forms an outer surface and an opening forming an inner surface. The inner surface includes a first interior diameter adjacent a distal end of the opening and a second interior diameter adjacent the first interior diameter. The second interior diameter is greater than the first interior diameter and forms a lip and at least a portion of the second interior diameter includes threading.
In one aspect of the embodiment, the closed position of the hinge nut is secured by a fastener towards a distal end opposite the hinge pin. In another aspect of the embodiment, the fastener engages a nut where the nut is press fit into a hole located between the inner surface and outer surface of the hinge nut.

The hinge nut is attached to the one of the distal ends forming the lip. The hinge nut includes at least two portions attached to each other by a hinge pin adjacent a distal end of each portion and the two portions are configured to be moved between an open position and a closed position. The closed position forms an outer surface and an opening forming an inner surface. The inner surface includes a first interior diameter adjacent a distal end of the opening and a second interior diameter adjacent the first interior diameter.

Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
Embodiments of the invention provide for an apparatus for a battery-powered valve in a meter coupling. In an embodiment of the invention, a battery-powered valve, such as a shut-off valve, in a meter coupling may be coupled to either end (the inlet or outlet) of an existing meter. The meter coupling also includes an inlet and outlet, where one side is connected to the meter and the other side is connected to the existing plumbing. The meter includes components for measuring the volume of fluid, such as water or gas, flowing through the meter.
The battery-powered valve may be contained within a housing of the meter coupling. The meter coupling may include a motor gear drive assembly, such as an actuator controller, that controls the valve, along with an internal transceiver or receiver to receive instructions to control the valve or the valve may be in communication with an external transceiver or receiver. Thus, an external transceiver or transmitter may transmit instructions to the motor gear drive assembly to open or close or partially open/close the valve. The valve may be powered by batteries, such as rechargeable or replaceable batteries that are contained within the meter coupling. In operation, the meter includes an inlet that attaches to the supply of fluid and an outlet that attaches to the fluid lines of the residential or commercial structure. The meter coupling that includes the battery-powered valve may be attached to the inlet or outlet of the meter. The transceiver of the valve receives instructions to open, close or partially open/close the valve to either allow, stop or restrict fluid flow. The valve then automatically opens, closes or partially opens/closes to provide sustenance flow to the occupant in response to the instructions. The valve may also be cycled intermittently to keep it from sticking so that it will continue to work.
The meter coupling may be coupled to the meter by a hinge nut so that the meter coupling can be easily retrofitted to existing meters. The hinge nut includes two halves or portions that are attached to each other at one end by a hinge pin. At an opposite end from the hinge pin, a fastener secures the ends of the hinge nut together. The fastener may be separate or built into the hinge nut. Thus, hinge nut can be easily moved from an open position to a closed position around an inlet or outlet of an existing meter to couple a meter coupling to the inlet or outlet of the existing meter and subsequently secured with the fastener. In order to couple the hinge nut to the inlet or outlet of the meter, threading of the hinge nut mates with corresponding threading on the outer portion of the inlet or outlet of the meter. Further, a retaining lip of the hinge nut engages a corresponding lip of the meter coupling on the inlet or outlet of the meter coupling. The meter coupling may also include a slip nut to tighten the end of the meter coupling lip against the hinge nut retaining lip to seal the meter coupling inlet or outlet, hinge nut, and meter inlet or outlet.
In operation, the inlet or outlet end of the meter coupling that includes the lip is placed facing the inlet or the outlet end of the meter. The hinge nut halves are moved from an open or “open hinge” position to a closed or “closed hinge” position around both the meter coupling end and the meter end. The hinge nut halves are then secured to each other with the fastener. The lip of the meter coupling is retained on the interior of the hinge nut by the retaining lip of the hinge nut halves and the threading of the meter engages with the corresponding threading of the hinge nut halves. A gasket or seal or washer may be placed between the threading of the meter and the meter coupling. The slip nut of the meter coupling is then tightened so that the end of the meter coupling lip is tightened against the hinge nut retaining lip. In this way, the meter coupling is able to be attached to an existing meter that would otherwise need to be removed in order to rotate the meter coupling along the threading of the meter.
Referring now to the drawing figures in which like reference designators refer to like elements, there is shown in
The meter coupling 110 may be coupled to either end of a fluid flow meter 140 with hinge nut 130. The threading 110A on the end of the meter coupling 110 allows the meter coupling to connect to either the supply lines from the utility company supplying the water or gas or the supply lines between the meter and the structure or dwelling. Similarly, the threading on the ends of the inlet or outlet of the meter 140 allows the meter 140 to connect to supply lines from the utility company supplying the water or gas or the supply lines between the meter and the structure or dwelling. Once hinge nut 130 is installed and rotated it will thereby tighten and secure the lip 110C of the meter coupling against a corresponding retaining lip 190 of the hinge nut. The hinge nut 130 is threaded on to the meter threads until tightening and securing the lip 110C of the meter coupling against a corresponding retaining lip 190 of the hinge nut which seals with seal 110D.
The meter coupling 110 may be secured to the meter with hinge nut, which is made up of the hinge nut components: hinge nut half 130A, hinge nut half 130B, hinge nut fastener 130C, hinge nut fastener nut 130D, and hinge pin 130E. The hinge nut halves 130A, 130B may be permanently attached by the hinge pin 130E or the hinge pin may be removable. The hinge nut includes a face 150 facing the meter coupling and an opposite face 160 facing the meter. As can be seen, the hinge nut 130 is made up of two halves 130A and 130B that are attached to each other to form the hinge nut. Thus, face 150 is made up faces 150A, 150B of the respective half and face 160 is made up faces 160A, 160B of the respective half.
On the exterior of the hinge nut 130, hinge nut fastener 130C and hinge nut fastener nut 130D secures the hinge nut halves 130A, 130B to each other. The hinge nut halves 130A, 130B may include grooves or channels or holes on the exterior sized and shaped for the corresponding hinge nut fastener 130C and hinge nut fastener nut 130D. The hinge nut fastener nut 130D and/or the hinge nut fastener 130C may be molded into the hole on the respective hinge nut half. In this way, the respective hinge nut half would include a molded-in threaded insert and the opposite hinge nut half would include corresponding female threading, so the two can be bolted together. Alternatively, the hinge nut fastener nut 130D may be press fit into the hole on the exterior of the hinge nut (in between the inner and outer surface of the closed hinge nut) when it is secured to the hinge nut fastener 130C to secure the hinge nut halves 130A, 130B together. An outer surface of the hinge nut is formed when the hinge nut halves are moved to a closed hinge position. The figures depict the surface as substantially hexagonal in cross-section, however, any polygonal or cylindrical cross-section is within the scope of this invention.
The opening in the hinge nut 130 forms an interior or inner surface of the hinge nut that is cylindrical in cross-section when in the closed position. The inner surface of the hinge nut includes a include a retaining lip 190 formed by the respective halves on one end of the opening. While the retaining lip is shown as cylindrical in cross-section, the retaining lip being polygonal in cross-section is within the scope of this invention. Further, the hinge nut halves include threading 180 formed by the respective halves adjacent the retaining lip towards the opposite end of the opening. The retaining lip is located towards the end adjacent face 150 facing the meter coupling and the threading is located towards the end adjacent face 160 facing the meter. As can be seen, the interior diameter of the portion of the inner surface of the hinge nut with the threading is greater than the interior diameter of the portion of the inner surface of the hinge nut with the retaining lip, which thereby forms the retaining lip. The retaining lip is configured to engage or retain lip 110C of the meter coupling with a gasket or seal or washer 110D in between and the threading is configured to engage the corresponding threading on the inlet or outlet of the meter 140.
As depicted in
The battery-powered valve, the meter coupling 110, the hinge nut 130 components, and the meter 140, may be manufactured from materials including, but not limited to, bronze, cast iron, stainless steel, plastics or other non-corrosive materials, or any combination of the materials. The meter 140 may be cast into place or assembled separately. The meter coupling 110, including the housing 120 for the battery-powered valve and electronic components, may be molded into place or assembled separately and coupled to the meter 140 with the hinge nut 130.
Now referring to
As shown in
When rotated or engaged by a user, the actuator 200 may transition between a first position and a second position to manually control the opening and closing (or at least partial opening and closing) of the valve 210 in the event of an electrical, mechanical, and/or communication failure or fault of the internal power supply 240. For example, as shown in
As shown in
It is to be understood that, as described herein, the system signal may also be a command, message, or instruction to open or close the valve 210. In some embodiments, the system signal may also include the fluid parameter signal indicative of the amount of the fluid passing through the valve 210 and/or the flow rate of the fluid, the parameter data, the identification data, and/or the time data. As a non-limiting example, the parameter data may include or refer to the settings of the flow meter 140 and the valve 210, such as the meter parameters in cubic feet or gallons and how far the valve 210 opens and closes or whether the valve 210 stops in between the fully open and closed positions (i.e., partially open or closed). The identification data may include the duration or period of time that the valve 210 is opened or closed, or in an open-close cycle. Further, the system signal received from the remote device 290 may also contain a command update message or a data update message in order to update the system components of the housing 120 described herein. The command update message may be an instruction for the processing circuitry 250 to follow, such as disabling or deactivating the system. A data update message may include a firmware update for the processing circuitry 250, sensors, and/or logic.
As mentioned above, the housing 120 includes the internal power supply 240 disposed therein. The internal power supply 240 is in communication with and is configured to supply power to any of the processing circuitry 250, orientation device 220, and/or the motor gear drive assembly 230 for controlling the opening and closing of the valve 210. According to one or more embodiments, the internal power supply 240 may include one or more batteries that are configured to supply power to the various components of the housing 120 until the batteries run out of charge. Once the batteries run of out charge, a user or operator may remove the depleted batteries and replace them with charged batteries.
Additionally, and or alternatively, in one or more embodiments, the processing circuitry 250, orientation device 220, and/or the motor gear drive assembly 230 may also be in communication with an external power supply 300, which can be used as a primary and/or secondary power source in addition to, or in place of, the internal power supply 240. The external power supply 300 may be a power source disposed within a commercial or residential building, power generator, battery pack, motor or electric vehicle, or any other device configured to provide power output to the components disposed within the housing 120.
Prior to, during, or after operation of the fluid flow meter 140, the processing circuitry 250 is further configured to measure a charge level of the internal power supply 240 in order to maintain proper operation of the processing circuitry 250, motor gear drive assembly 230, and/or orientation device 220. Once the charge level is measured, the processing circuitry 250 may compare the measured charge level to a predetermined threshold stored within the memory 270 or retrievable from remote device 290. The predetermined threshold may be a predetermined minimum charge level necessary to maintain proper or normal operation of the processing circuitry 250, motor gear drive assembly 230, and/or orientation device 220. If the measured charge level falls below the predetermined threshold, the processing circuitry 250 may automatically generate and transmit at least one of an audible, verbal, or tactile alert to the remote device 290 so that a user or operator is notified that the internal power supply 240 is failing or needs to be replaced. In one or more embodiments, when it is determined that the internal power supply 240 is failing, the housing 120, and the components disposed therein, may instead be powered by the external power supply 300 as a backup power supply. In the event of a mechanical or electrical failure from the internal power supply 240 and/or external power supply 300, the actuator 200 may be manually engaged by the user or operator to open and close the valve 210. However, it is to be understood that the actuator 200 may also be manually engaged by the user to open and close—or partially open and close—the valve 210 at any other time desired by the user or operator.
