摘要： Excess flow shutoff valve comprising a valve body, a valve plug, a partition, and an activation component where the valve plug, the partition, and activation component are disposed within the valve body. A suitable flow restriction is provided to create a pressure difference between the upstream end of the valve plug and the downstream end of the valve plug when fluid flows through the valve body. The pressure difference exceeds a target pressure difference needed to activate the activation component when fluid flow through the valve body is higher than a desired rate, and thereby closes the valve.

摘要： The present invention provides, in part, a valve assembly and method that maintains balance of flow to pressure. In one embodiment, the present invention includes a main body component, a chamber body component, a fluid control plate and seal, and a chamber cap. The chamber body component is adapted to slidingly engage the main body member. A spring assists in biasing the chamber body component in position within the main body component. The chamber cap with a sealing ring assists in preventing backflow of fluid into an outer body or tube member while also providing an opposing force to movement of the chamber body member within the main body member. A sealing ring is also provided around the head portion of the chamber body member. An additional sealing ring can be provided in a cavity on the outside of the main body member.

摘要： Internal valve apparatus are described. An example internal valve includes a body having a valve seat disposed between an inlet and an outlet. A flow control member operatively coupled to the body moves between a first position in which the flow control member engages the valve seat to restrict the flow of fluid through the valve and a second position in which the flow control member is spaced from the valve seat to allow the flow of fluid through the valve. The example internal valve further includes a removable actuation member disposed within the body and responsive to a fluid pressure to cause the flow control member to move between the first and second positions.

摘要： The invention is directed to an excess flow valve having a feather gasket positioned near a valve seat. The excess flow valve also has a piston assembly with a first disc-shaped piston and a second disc-shaped piston. Each piston also has at least one orifice defined therein and has an upstream face and a downstream face. In one embodiment, the excess flow valve has a spring positioned in the housing against the downstream face of the second piston such that the spring exerts a force on the second piston in a direction opposite the general fluid flow direction. When flow forces acting on the piston assembly sufficiently exceed the spring force acting on the second piston, the piston assembly moves in the flow direction until a stop engages a valve seat to shut off fluid flow through the valve. The feather gasket reduces a bypass flow past the valve seat.

摘要： A flow shut off valve for residential water line pressure includes a housing having an inlet, an outlet and a passage there between with a valve seat in the passage. A valve element is slidably mounted within the passage and includes a cavity open to the inlet and orifices partially restricting flow from the cavity to the passage. A spring biases the valve element toward the inlet. Reduced back pressure at the outlet drives the valve element into a closed position with a sealing surface against the valve seat to terminate flow. The restrictive orifices in the valve element extend from the cavity to the periphery of the valve element and, in a position toward the inlet, the restrictive orifices are closed by the housing to block communication between the inlet and the outlet. In an intermediate position, the orifices are open and the sealing surface is not against the valve seat. A motion damper may be employed to allow for start-up conditions on sprinkler systems and the like. The flow shutoff valves are contemplated for employment with household appliances using water and sprinkler systems.

摘要： A valve assembly includes an automatic excess flow shut-off mechanism for preventing excess flow between an inlet and an outlet of the assembly. The excess flow shut-off mechanism is adapted to automatically stop fluid flow through the valve assembly when the flow exceeds a specified flow rate. The excess flow shut-off mechanism prevents flow when it's set and allows flow when it's reset. The valve assembly also includes a manual set mechanism for setting the excess flow shut-off mechanism even when there is no excess flow. The valve assembly additionally includes a manual reset mechanism for resetting the shut-off mechanism and for allowing excess flow.

摘要： An excess flow valve having a housing, a valve seat, a poppet and an adjusting ring. The adjusting ring lies within a bore in the housing and there is an opening through the housing permitting access to the adjustment ring from outside the bore of the housing. Rotation of the adjusting ring controls the maximum travel distance between the poppet and the valve seat. In an embodiment a travelling valve guide is rotatably mounted within the adjustment ring to change the maximum travel distance between the poppet and the valve seat. A spring may bias the poppet and the valve seat away from each other.

摘要： The riser line shutoff valve where oxygen flows into the valve from the inlet and through an orifice in the piston. This orifice creates differential pressure between the upstream and downstream side of the piston. When the differential pressure across the piston exceeds the spring load and friction between the piston and the valve body, the piston moves to the left and seats on the brass probe in the conical area of the piston, preventing the flow of oxygen. The valve will not open until the upstream pressure is removed. The base of the brass probe has holes, allowing oxygen to flow out of the outlet port when the valve is open. The probe is threaded into the probe base allowing for valve adjustment for proper operation. The spring simultaneously serves the functions of retaining the probe base and providing a piston load to keep the piston open until the critical flow rate is reached.

摘要： In a method for a safety valve plus such a safety valve, the safety valve has the form of a valve body axially displaceable in a cavity with an inlet on either side of which are arranged outlets, whereby liquid and/or gas flow takes place from the inlet and past the valve body via a flow path to the outlets. On the valve body side, the flow path is provided with a structure that raises the friction in relation to the liquid and/or gas flow between the inlet and outlets.

摘要： An automatically operating valve for use for example in a forecourt fuel pump has a body (10) defining a flow passage (20) within which is formed a valve seat (22), the body having a weakened zone (16) around the flow passage (20) such that an impact on the body will fracture the body at the weakened zone. A valve member (30) is mounted for movement within the flow passage (20) and is engageable with the valve seat (22) to close the valve. A closing mechanism effects movement of the valve member (30) to its closed position in the event that the body (10) is fractured at the weakened zone. Further, the valve member (30) is configured to move to its closed position under the influence of excessive flow of liquid through the flow passage (20).
