Adjuster for pressure responsive safety valve - has valve closure held against seat by spring with pressure set by adjuster screw

摘要

The valve is controlled by the pressure of the flow medium with a pre-pressure side pressure chamber in the valve housing. This chamber has a face wall controlling a main closure part and at least one throttle channel which connects the chamber interior with the pre-pressure side. A control channel from the chamber interior to the low pressure side has a spring-loaded control closure part. An accommodating bore (15) is connected at one end to the pressure side (2) and at the other to the chamber interior (17). A pressure-reactive adjuster (16) for the valve closure (10) is arranged in the bore.
