The present invention is related to a fluid manifold and a direction control valve thereof, more particularly to a fluid manifold with a substantially spherical body and the direction control valve there of.
Various valve constructions and arrangements are known for controlling the flow of gas, liquids or slurries in association with piping and conduits. In certain applications, it can be desirable to provide selective fluid communication between one and more of a plurality of individual pipes intersected by a main pipe. This can be accomplished by providing each of the individual pipes with its own respective isolation valve, or by installing a diverter or “Y” valve in communications with the main feed pipe.
In some applications, it may be desirable to prevent reverse flow through a diverter valve and therefore, suitable flow check mechanisms can be provided so as the fluid only flows in one direction.
Although arrangements of the above description are commonly employed to permit a selected fluid direction of flow, complications sometimes arise due to hostile liquid environments or from obstacles obstruction preventing liquid gravity flow inside a pipe line.
Therefore in many applications, the nature of the fluids being piped and controlled dictates the type of valve suitable for the application. For example, in facilities which handle and treat sewage, the influent flow can often be abrasive or corrosive. Equipment installed in these applications must be specially adapted for rigorous service requirements. Not only does this frequently limit the valve type suitable for use, it can also significantly impact influent flow or even possibly maintenance requirements in which create additional expense for the consumer.
Most sewer systems often operate using gravity fall or what's more commonly referred to within the construction trades as slope or pitch rates. Slope rate is commonly used to evacuate a liquid waste stream from various structures and directs it into a main line or what is more commonly known as a sewer line.
Slope rates are typically dictated by building codes in which state “the rate of slope must be a quarter inch for each one foot of pipe run”. However, field conditions such as utility obstructions or in some case a lack of structural elevation does not always allow for a proper slope angle. In these cases as long as the pipe run maintains a minimal slope angle without any dips, it should still function without too much worry about extensive backup.
Building codes also limit the maximum allowable slope angle to “one foot for every four feet of pipe run”. The limiting of slope is meant to prevent waste water flowing too fast upon entering into a sewer system in which may cause interference of disruption to an existing sewer flow. Also other issues exist when having an extreme amount of slope angle, particularly in regards to household waste water if flowing too fast. In this instance a fast flow can create siphoning resulting in the drying of water barriers held inside sink traps, these barriers are used to prevent sewer gases from entering into the home from the sewer system.
Most patent applications didn't include unique design changes which enhance valve durability or flow efficiency. Mostly, the designs didn't take in consideration about housing size or fluid flow dynamics. Further, most directional valves currently offered affect slope angle due to installation angles required for mating to an existing pipe line or by inlet and outlet height in relationship to pipe line elevation. The current offered directional valves do not offer ground level accessibility for switching a fluid flow direction.
For example, the US patent with patent number of U.S. Pat. No. 4,578,188A (hereinafter as Cousino) teaches a sewage flow diverter comprising a relatively large drain, a weir in the bottom of the drain, an inlet communicating with the drain adjacent the bottom thereof, and upstream of the weir, an outlet communication with the drain downstream from the weir, the opposite ends of the inlet and outlet being adjacent, opening means located between the opposite ends of the inlet and outlet, said opening means so located and sized to permit relatively low flows of liquid in the inlet to pass through the opening and relatively high flows to be propelled by the kinetic energy of the flow form the inlet into the outlet, and means to conduct the flow passing through the opening means to a sanitary interceptor.
Cousino's teachings refer mainly to cases when high sewer flows are of concern and where in low sewer flow situations may inhibit a flow rate based on the design principle of his apparatus.
In another example, The PCT application of WO2010088091 (hereinafter as Dvorak) teaches a system for diverting water comprising: a filter basket; a drain pipe providing a first channel and a second channel; and a diverter capable of diverting water from the filter basket alternatively towards each of the first and second channels.
The invention of Dvorak is reliant upon influent flow through a filter basket in which could be considered flow restrictive and further, if the filter basket requires added maintenance for occasional cleaning would not be cost effective for the consumer.
In another example, the US patent of U.S. Pat. No. 5,423,343A (hereinafter as Crouch) teaches the principle of testing a new sewage main line, the valve assembly is manipulated from above ground without excavation to connect the lateral to the new main line and block off the now unneeded old discharge line. A cable extends from the valve assembly to above ground. Manipulation of the cable rotates the valve to a position enabling flow from the lateral line to the new main line, while at the same time blocking off the old discharge line.
The invention of Crouch is a temporary solution when intersecting two sewer pipes together, wherein a diverter valve is used to check the integrity of a new pipe line.
Most diverter valve internal components are often constructed using some types of plastics or metals or a combination of both. However, the downfalls of most diverter valves are taking in consideration of contaminate types or solids commonly associated with some influent application. For instance, inside sewer systems contaminate types can vary form household chemicals inter-burst with industrial chemicals and solids intermixed within various water streams. These water streams can be often corrosive to both metals and plastics. Moreover, solid buildup within or on internal movable components may cause sticking, seizing or pitting, these contribute to a loss of integrity and eventual fluid bi-passing or external housing leakage.
Metals well known to resist corrosion are often used in construction of a valve system, they often involve two dissimilar metals, for example a copper or bronze housing may be working in conjunction with a stainless steel ball or flap. When these dissimilar metals are exposed to conductive fluids or active electrolytes, bi-metal electrolytic reactions occur. These reactions encourage electrolytic metal erosion which eventually leads to physical damage to both internal and external components.
