Liquid pressure regulator with a spring loaded membrane has a progressive pressure relief insert and an asymmetric two pressure levels setter

摘要

The regulator has an enveloping body (1) with a closure diaphragm (7) on which a spring (5) acts. The body has an entrance (2) for pressure liquid and an exit (3) towards a pressure liquid application apparatus. The body is provided at bottom with a closure plug (8) having an adjustable axial position for achieving depressurization position or free passage, and at top with a compression spring abutting against flange of an asymmetrical intermediate body, the inversion of which bringing about two different preloading positions of spring to provide two regulator adjustment pressures.
