YK43X air pressure reducing valve

Gas pressure reducing valve is mainly used for gas pipelines, such as air, nitrogen, oxygen, hydrogen, coal gas, liquefied gas, natural gas and other gases. This series of pressure reducing valve is a pilot piston pressure reducing valve. It consists of two parts, the main valve and the pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting and adjusting the spring pressure, the outlet pressure changes are sensed by the diaphragm, and the size of the over-flow area of the main valve throttling part is adjusted by the pilot valve opening and closing to drive the piston to realize the function of pressure reduction and pressure stabilization.

YK43X air pressure reducing valve knowledge

(1) Pressure adjustment range: It refers to the adjustable range of the output pressure P2 of the pressure reducing valve, within which the required accuracy is required. The pressure regulating range is mainly related to the stiffness of the pressure regulating spring.

(2) Pressure characteristics: It refers to the characteristics of the output pressure fluctuation caused by the input pressure fluctuation when the flow rate g is constant. The smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve. The output pressure must be lower than the input pressure—the set value does not substantially change with the input pressure.

(3) Flow characteristics: It refers to the persistence of input pressure-timing, output pressure changes with the change of output flow g. When the flow rate g changes, the smaller the change in the output pressure, the better. Generally, the lower the output pressure, the smaller the fluctuation with output flow.
