摘要： An arrangement for managing a liquid medium, such as water, combines a pressure-reducing valve with two backflow prevention valves. Both the pressure-reducing valve and the two backflow prevention valves may be integrated into a common housing, specifically with both backflow prevention valves in an inlet chamber of the housing, wherein the inlet chamber and an outlet chamber of the housing are either fluidly coupled or isolated from one another by the pressure-reducing valve depending on the outlet chamber pressure prevailing in the outlet chamber. In some instances, a manually actuatable shut-off valve may be integrated into the housing. The manually actuatable shut-off valve may selectively keep the pressure-reducing valve in a closed position or allow the automatic opening and closing of the pressure-reducing valve depending on the outlet chamber pressure prevailing in the outlet chamber.

A valve controlled opening cooperating with the connecting arm of the stem, is located between the inlet port and the regulating chamber. The valve controlled opening is adapted to adjustably restrict the flow of gas between the inlet port and the regulating chamber responsive to movement of the connecting arm. A main spring is provided for engaging the diaphragm and urging it toward valve controlled opening. The base of the stem includes a lower surface that is channeled so as to assist the flow of gas from the valve controlled opening to the regulating chamber.

摘要： A monodirectional intake pressure stabilization structure of pneumatic tool includes a tool main body and a pressure stabilization unit. The pressure stabilization unit is disposed in a first directional intake passage formed in the tool main body for controlling the pressure of the air guided by the first directional intake passage into an air chamber of the tool main body. Accordingly, excessively great intake pressure can be avoided so as to avoid over-torque output of the pneumatic tool. In this case, the pneumatic tool can stably output power within a safety range in accordance with the requirements of actual use. The pressure stabilization unit can be a pressure stabilizer or a pressure relief valve.

摘要： A constant flow regulating valve of the type described in U.S. Pat. Nos. 6,026,850 and 6,209,578 includes a closure mechanism configured and arranged to override the modulating mode of the valve and to close the valve at fluid inlet pressures both below and above the valve's threshold level. The closure mechanism may be selectively deactivated to thereby allow the valve to assume its normal pressure responsive regulating functions. Embodiments of the regulating valve incorporate pressure relief devices and vent seals, with configurations suitable for incorporation into the trigger assemblies of portable sprayers.
