FIELD: instrumentation engineering. SUBSTANCE: the pressure regulator has reducing and safety valves 8 and 10 and control piston 6 loaded by spring 7 placed in casing 1. Guide surfaces 12 and 13 of valves 8 and 10 together with casing recess 5 make up damper chamber 14, which communicates with outlet duct 3 through throttling duct 15 made in the casing. It provides for a smooth (without any impact) fit of the safety valve onto the reducing valve at its closing. EFFECT: enhanced durability of pressure regulator. 2 dwg |
