The gas pressure reducing valve of Dalian compressed air pipeline is suitable for working under the environment of temperature lower than 70 ℃. The inlet pressure is reduced to the specific demand pressure by the flow restriction of the opening and closing parts. With the help of the energy of the medium itself, the pilot valve opens and closes the driving piston to adjust the flow area of the throttle part of the main valve, so as to realize the pressure reduction and pressure stabilization function.

Form and size of gas inlet joint; Form and size of joint at gas outlet. The specification of the gas pressure reducing valve shall be confirmed according to your use conditions. Because the pressure reducing valve of Dalian compressed air pipeline contains high-pressure gas. Therefore, it is very important to confirm the working conditions of pressure reducing valve products.

For the pressure reducing valve directly connected to the cylinder of Dalian compressed air pipeline, the maintenance and use shall comply with the relevant high-pressure gas management regulations and internal rules. Incorrect operation will lead to gas leakage or damage to the pressure reducing valve, resulting in serious accidents.

Moisture detection, i.e. the determination of moisture and impurities in the pipeline gas, is currently used by dew point method, capacitance method, electrolysis method, etc. Cleanliness detection is to determine whether the inner wall of the pipeline is clean by measuring the pollutant particles in the gas transmission and distribution system, mainly by light scattering method and membrane filtration method.
