摘要： A metering valve assembly for use in sanitary applications and method of use is disclosed. The metering valve assembly has a relief valve hydraulically controlling a pilot valve covering a water supply inlet. The relief valve is controllably closed by a damping mechanism substantially independently of typical variations in water supply temperature and pressure.

摘要： A metering valve is provided having a piston assembly mounted for movement between open and close modes. The piston assembly is biased to assume a close mode. The piston assembly assumes an open mode only when a predetermined external force is applied to a valve actuating element forming a component of the metering valve. When the external force is removed, the piston assembly automatically returns to the close mode. The rate of movement of the piston assembly during a first segment of travel from the open mode to the close mode is substantially slower than the rate of movement during a second segment of the travel.

摘要： A self-actuated valve that functions after a predetermined time delay. The valve can be used to determine the time a fluid is at a point of use or to control the flow of fluid to or from a point of use. The valve can be self resetting. Basically, the valve assembly consists of a spool-shaped piston positioned in a chamber of a housing having a continuously interconnected inlet, an optional outlet, and an exhaust port. The larger end of the spool-shaped piston is acted upon by the pressure within an accumulator volume and the small end of the piston forms a seal, thereby normally closing the exhaust port from the inlet. The piston is provided with a flow restrictive means that communicates the inlet with the accumulator. The accumulator can be provided with an optional venting valve. The time delay vent valve works in the following manner. Fluid flows into or through the valve housing and passes through the piston''s flow restrictive means into the accumulator. Since the accumulator end of the piston has a larger area than the inlet end, the total force on the accumulator end of the piston will exceed the total force on the inlet end after a period of time. The force differential moves the piston, which opens the seal, and allows the fluid to flow from the inlet through the exhaust port. The time delay is readily changed by simply changing the flow restrictive means in the piston. The valve can be self-resetting or can be externally reset by several techniques.

摘要： A faucet includes a faucet housing defining a mixing chamber and a dry chamber, a valve assembly, and a damper assembly. The valve assembly includes a main shaft having a first end and a second end, a knob coupled to the first end, a mixing plate coupled to the second end, a main seal coupled to the main shaft, and a first biasing member disposed around the main shaft. The first end is disposed within the mixing chamber and the second end is disposed within the dry chamber. The damper assembly includes an outer cylinder disposed within the dry chamber, a piston extending at least partially into the outer cylinder, and a second biasing member disposed within the outer cylinder. The piston has an interference surface configured to contact the knob, and the second biasing member is configured to bias the piston.

摘要： A valve assembly capable of converting a small leak of a device into a measurable, relatively larger or “burst” flow event is described. In certain embodiments, the valve assembly includes a compliant chamber and, following pressurization of the device, permits flow when the pressure in the compliant chamber drops to a configured fill pressure and restricts (or prevents) flow when the pressure in the compliant chamber increases to a shut-off pressure. The disclosed valve assemblies may be incorporated into a leak detection assembly capable of transmitting usage and/or alarm data to a central service.

摘要： A push type water tap with automatic closing functions wherein a through valve tube and a protruding bottom tube are set separately into the chambers of the main body. A lifting valve lever is assembled into the valve tube and bottom tube. A stop ring can be abutted onto the water stop ring flange for stopping water supply. A restoring spring is set between the top of the valve lever and the lock-joining seat, and supports the valve lever and the push button. A single-way check ring is sleeved on the bottom of the valve lever to keep contact with the wall of the bottom tube. A resettable regulating space is formed by the gap between the bottom of the valve lever and the sealing surface. A resettable regulating water channel is set on the bottom of the valve lever to guide water into the regulating space.

摘要： A handle assembly for providing dual flush functionality to a flush valve. The handle assembly comprising a handle and a plunger engagable with each other. The plunger axially slidable in a bush disposed between the handle and the flush valve. The bushing having a passage for receiving the plunger. The plunger having a first and a second axis along which the plunger may travel through the passage. Movement of the handle moves the plunger from first axis to the second axis wherein actuation of the flush valve by the plunger along the first axis results in a different flush volume than actuation along the second axis.
