How to adjust the size of gas pressure reducing valve

Generally speaking, the flat pressure valve cannot be adjusted, and the air outlet has a hard air pressure setting; The medium pressure valve has an adjustable knob. In general, the left screw is used for decompression and the right screw is used for pressurization. The pipeline booster valve can only be disassembled and adjusted when the accessories are ready, otherwise there is a danger of air leakage.

For the convenience of operation and maintenance, gas pressure reducing valves are generally installed vertically on horizontal pipelines. During installation, attention should be paid to make the flow direction of the medium in the pipeline consistent with the direction of the arrow on the valve seat. In order to prevent the pressure behind the valve from overpressure, a pressure reducing valve should be installed at a distance of not less than 4M from the valve outlet.

Extended data:

The gas pressure reducing valve uses the opening of the opening and closing parts in the control valve body to adjust the flow rate of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts is adjusted by the pressure behind the valve to keep the pressure behind the valve within a certain range, and cooling water is injected into the valve body or behind the valve to reduce the temperature of the medium. This kind of valve is called decompression and desuperheating valve.

The characteristic of gas pressure reducing valve is to keep the outlet pressure and temperature within a certain range under the condition of changing inlet pressure. Generally, this valve should be installed horizontally in the pipeline.
