Description

Technical Field

[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through adjustment, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From the viewpoint of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. Then, by relying on the adjustment 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 kept constant within a certain error range. The clamping mechanism of the pressure detection structure of some pressure reducing valves is not good enough, which can easily affect the detection efficiency. The device is not convenient to adjust, and it is not convenient to detect pressure reducing valves of various sizes.
