摘要： A fire suppression sprinkler system convertible between a wet and a dry mode of operation is disclosed. The system features a field convertible valve having a bypass loop with a bypass valve for selectively configuring the valve for wet or dry mode operation. For dry mode operation, the bypass valve is open. The field convertible valve also has a system actuator, a gas control valve and a water supply shut-off valve which are open in the dry mode. In the wet mode of operation, the bypass valve is open and the gas control and water supply shut-off valves are closed. The field convertible valve operates in a latch mode controlled by the system actuator in the dry mode, and as a flapper valve in the wet mode of operation. A method of converting the mode of operation of the sprinkler system is also disclosed.

摘要： A passive, exhaust pressure actuated valve assembly for placement inside a tubular exhaust conduit is pivotally mounted to an off-center axle for rotation between fully closed and fully opened positions. A bias element forces the valve flap toward the fully closed position. The valve flap is shaped in a manner enabling use of the interior surface of the exhaust conduit to define stops at the full closed and full opened positions. The valve flap shape, in conjunction with the bias element arrangement, enables the flap to lie substantially parallel to a longitudinal axis of the conduit in the fully opened position, which provides for minimum back pressure in the conduit.

摘要： A fluid flow control valve is disclosed. This valve includes a housing which defines a central passageway having fluid inlet and fluid outlet openings. A pressure responsive element is disposed within the passageway for selectively opening and closing the inlet opening to fluid flow in response to fluid pressure exerted thereon at the inlet opening. A mechanism is provided within the passageway for exerting a bias force against the pressure responsive element which is sufficient to close the inlet opening to fluid flow absent a pre-established level of fluid pressure exerted on the pressure responsive element. A fluid filter element is also disposed within the passageway; and a retainer device is positioned for removably securing the filter element within the passageway.

摘要： A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, a flexible diaphragm and a support member. The valve housing is configured to pass fluid through the fluid conduit. The flexible diaphragm provides a self-seal of the fluid conduit, and comprises an area larger than an area of the fluid conduit and a periphery. The support member is configured to retain a portion of a flexible diaphragm. The support member and flexible diaphragm are configured to position the flexible diaphragm against the valve seat to seal the fluid conduit in a closed position of the self-sealing valve, and to facilitate movement of at least a part of the periphery of the flexible diaphragm in a first direction away from the valve seat to an open position.

摘要： A self-sealing valve is used to fill, empty, and control the volume of fluid within an inflatable device. The valve includes a housing having a fluid inlet, a valve seat and a valve assembly that selectively covers the fluid inlet to provide a self-seal. The valve assembly includes a support member that suspends a flexible diaphragm in a closed position within the valve housing while allowing movement of at least part of the periphery of the diaphragm away from the valve seat to an open position and back towards the valve seat to a closed position. The support member may be manually moved to any of the multiple open positions, either to enable fluid release or to enhance fluid injection. With the injection of fluid, the diaphragm assumes an open position, allowing fluid influx. A fluid pressure created within the device assists in maintaining the diaphragm in the closed position.

摘要： A self sealing valve includes a diaphragm (602) positioned within a valve housing (606) by a movable hanger arm (610) which suspends the diaphragm from a mounting point (612) in the center of an air inlet (614). The hanger arm (610) is a rotating diaphragm hanger that has one end secured adjacent to an inner wall (618) of the air inlet (614) by a pair of pins (634). There is a contoured section (648) between the hinge pins (634) of the inner wall which interfaces with a contoured end (650) to provide for at least four distinct interaction possibilities. A first retains the hanger arm (610) in a valve closed position. A second causes the valve to exhibit a biased closed condition. A third locks the valve open and a fourth facilitates assembly.

摘要： A check valve or backflow preventer has a valve mechanism mounted to a valve cover for removal and replacement as a unit. The valve clapper is resiliently supported to accommodate variations in tolerance. The valve seat is removably secured within the valve body by compression of a resilient seal ring to engage opposed walls of the seat and body. A spring pretensioning member facilitates safe replacement and removal of the valve mechanism.

摘要： A two way check valve used in a water supply system including a hollow valve body forming a valve chamber with first and second valve seats located in this chamber. The body has an inlet and two outlet ports. A valve or gate member is mounted in the valve body and is capable of pivoting between the first valve seat and the second seat. An elongate coil spring biases the valve member to pivot towards and engage the first seat. Water can flow under pressure from the inlet to a first of the outlet ports but not to the second outlet port. Water can flow in a reverse direction into the first outlet port and is diverted by the valve member out through the second outlet port. The reverse flow is prevented from flowing out the valve inlet.

摘要： A check valve assembly mounted for engagement with a valve seat includes a flapper valve and a lever arm. The flapper valve includes a bracket pivotably mounted along a first hemisphere of the valve seat, a valve plate mounted to the bracket along a region generally spaced from a periphery of the valve plate, and a mounting assembly adjustably joining the valve plate to the bracket. The flapper valve has a closed position with the valve plate in sealing engagement with the valve seat about the periphery of the valve plate. The lever arm is pivotably mounted to the valve seat along a second hemisphere of the valve seat opposite the first hemisphere. The lever arm includes a lever surface disposed for moving contact with an engagement surface of the bracket and a biasing means for biasing the lever surface toward contact with the engagement surface.
