3 Terms and Definitions

3.1 Gas pressure reducer pressureregulator The usual variable inlet pressure is adjusted to the extent possible a stable outlet pressure device. 3.2 Rated inlet pressure (p1) ratedinletpressure Maximum inlet pressure reducer design. 3.3 rated outlet pressure (p2) ratedoutletpressure The maximum outlet pressure regulator designs. 3.4 safety valve opening pressure (pRV) pressureforthepressure-reliefvalveduringdischargetest Safety valve opening pressure limit, the value. pRV = 2p2, acetylene gas pressure reducer in any case should pRV Equal to 0.3MPa.

4 Overview

Gas pressure reducer is mainly used to maintain a constant outlet pressure and oxygen, acetylene, nitrogen, hydrogen and other high-pressure gas source Pressure, with lower inlet pressure, outlet pressure remain stable two effects. Gas pressure reducer main unit, safety valve, pressure gauge and other parts of the body, pressure regulator components. When screwing the regulator When the screw jack by making the shutter decompression valve for varying degrees of opening and closing, or adjusting the degree of vacuum gas stop Stop gas supply. On the body may be provided with a pressure reducer low pressure chamber communicating safety valve when the pressure reducer failure, low Pressure chamber pressure exceeds the safety valve opening pressure, the valve opens, the air escapes through the safety valve.
