CB/T3656-1994 Air pressure reducing valve

Pressure Reducing Valve is a Valve that reduces the inlet pressure to the required outlet pressure by adjusting. Steam Pressure Reducing Valve automatically keeps the outlet Pressure stable by relying on the energy of the medium itself. From the perspective of fluid mechanics, the Piston Steam Pressure Reducing Valve is a throttling element that can change the local resistance. That is, by changing the throttling area, the flow rate and kinetic energy of the fluid can be changed. The Big Flow Steam Pressure Reducing Valve can generate different pressure losses, so as to achieve the purpose of pressure reduction. Then, according to the regulation of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve is a certain error range.
