Fluid system separator, has load spring causing spring force over lifting unit when inlet side stopper of spring is provided on exhaust valve body so that spring acts on lifting unit and serves as load spring for valve body

摘要

The separator has upstream and downstream backflow preventers, and an exhaust valve body (126) that is fluidically arranged between the preventers. A load spring (182) is supported on an inlet side at a lifting unit (164), where pressure difference between input pressure and intermediate pressure in a closing direction of the spring counteracts at a valve body. The spring causes a spring force over the lifting unit when an inlet side stopper (146) of the spring is provided on the valve body so that the spring acts on the lifting unit and serves as the load spring for the valve body.
