摘要： A diaphragm valve includes a valve body with a valve seat disposed in a valve cavity surrounding a flow passage, a diaphragm movable between a closed position in sealing engagement with the valve seat and an open position axially spaced apart from the valve seat, and an actuator including an actuator housing assembled with the valve body and an actuating arrangement axially movable within the actuator housing between a first position holding the diaphragm in the closed position and a second position permitting movement of the diaphragm from the closed position to the open position. The actuating arrangement includes an actuator stem extending through a lower bore in the actuator housing, an actuator button disposed between a lower end of the actuator stem and the diaphragm for contact with the diaphragm, and a bearing member disposed between the actuator stem and the actuator button.

摘要： A valve arrangement having a main valve and having a pilot valve which is provided for controlling the main valve and which is inserted into a pilot valve receptacle in an insertion direction, wherein, through closure of the pilot valve, a pressure is able to be built up within a pressure chamber which is closed off by a diaphragm, whereby a valve seat between a main valve inlet and a main valve outlet is able to be closed off. By opening the pilot valve, it is possible to set a release of pressure within the pressure chamber by water flowing away via an inflow, connected to the pressure chamber, of the pilot valve receptacle and via a pilot valve inlet, adjoining the latter and formed by a main body of the pilot valve. A pilot valve outlet, formed by the main body, and via an outflow, adjoining said pilot valve outlet, into the main valve outlet, opens into the main valve outlet on the outflow side of the diaphragm. The pilot valve inlet and the pilot valve outlet are arranged offset from one another along a longitudinal axis of the pilot valve.

摘要： A valve includes a valve body having first and second fluid ports extending to a valve cavity, a seat carrier subassembly installed in the valve cavity and including a seat carrier body with a first annular inner wall defining a first flow aperture aligned with the first fluid port and a valve seat disposed in an annular recess surrounding the first annular inner wall, and a second annular inner wall defining a second flow aperture aligned with the second fluid port. A valve element is disposed within the valve cavity and is movable between a closed position sealing against the valve seat and an open position permitting fluid flow across the valve seat between the first and second flow apertures. An outer periphery of an orifice restriction is seated against an interior portion of one of the first annular inner wall and the second annular inner wall.

摘要： A high-pressure fluid discharge device that can adapt to large flow rates while being small in size has a diaphragm valve body that cooperates with a valve seat provided to a body to switch between communication and blocking between a first flow path and a second flow path. A pilot chamber and a valve chamber joined to the first flow path are sectioned by the diaphragm valve body, and the diaphragm valve body is provided with a pilot passage allowing communication between the valve chamber and the pilot chamber. The diaphragm valve body is also provided with a pilot-type spool valve that switches between communication and blocking between the pilot chamber and an excretion port.

摘要： A device for limiting or keeping constant a quantity of fluid flowing therethrough, includes: a housing with a front chamber and a rear chamber; a partition arranged in the housing with two or more openings; and a flow limiting element arranged in one or both openings. The flow limiting element includes a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate-like valve element mounted in the housing, substantially able to close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening. The valve element is fixed on one side and can move resiliently on the opposite side in the direction of the valve seat. A mould produces one or more injection-moulded products. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough.

摘要： A fluid control device includes a valve, a pump and a film valve. The valve includes a first main plate, a second main plate, a first side plate, and a valve chamber. The first main plate has a first vent hole, and the second main plate has a second vent hole. The film valve is disposed in the valve chamber. The first vent hole is positioned in a central region of the valve chamber, and the second vent hole is positioned in an outer end region of the valve chamber. The film valve is positioned between the first vent hole and the second vent hole. The film valve is fixed to the second main plate in a state in which an end portion on a side of the outer end region or an end portion on a side of the central region is capable of vibrating.
