Background

The pressure reducing valve is a valve which reduces the inlet pressure to a certain required outlet pressure through regulation and leads the outlet pressure to be automatically kept stable by relying on the energy of the medium. From the viewpoint of hydrodynamics, the pressure reducing valve is a throttling element with variable local resistance, namely, the flow speed and the kinetic energy of fluid are changed by changing the throttling area to cause different pressure losses, thereby achieving the purpose of pressure reduction. Then, the fluctuation of the pressure behind the valve is balanced with the spring force by means of the regulation of the control and regulation system, so that the pressure behind the valve is kept constant within a certain error range.
