How to adjust the gas pressure reducing valve if it accidentally moves?

The way to adjust the pressure reducing valve by careless movement is: usually there is a knob on the pressure reducing valve, which can be adjusted clockwise or counterclockwise. Clockwise rotation is usually used to increase the gas pressure, while counterclockwise rotation is used to decrease the gas pressure. When adjusting, you can refer to the pointer pressure gauge on the surface of the pressure reducing valve, which is generally adjusted to the green area, which is the normal pressure. Pressure reducing valve is an important gas equipment installed on the angle valve of liquefied gas cylinder to connect the angle valve and rubber hose, which can reduce and stabilize the output pressure. It has the advantages of simple structure, stable pressure, light weight and convenient adjustment and installation. It is mainly composed of air inlet, air outlet, handwheel, upper valve cover, lower valve cover, air inlet nozzle, breathing hole, upper air chamber, decompression chamber, valve gasket, lever, rubber membrane, spring and adjusting screw plug.
