Abstract

The invention discloses a pressure reducing valve, relates to a valve, in particular to the pressure reducing valve, and solves the defects of smaller pressure change section, incapability of adjusting the pressure reducing performance and complicated resetting of the pressure reducing performance through replacing a throttling element on a shunting pipe in a traditional pressure fluctuation valve. The pressure reducing valve comprises a valve body, an inlet end, an outlet end, a valve element module, a spring, two radial connecting pieces and two clamping rings; the valve element module is mounted in the valve body; the spring is sleeved on the valve element module; the inlet end is connected with one end of the valve body through one radial connecting piece and one clamping ring; and the outlet end is connected with the other end of the valve body through the other radial connecting piece and the other clamping ring. The pressure reducing valve belongs to the field of machinery.

Description

technical field [0001] The invention relates to a valve, in particular to a decompression valve, which belongs to the field of machinery. Background technique [0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to keep the outlet pressure automatically stable. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of decompression. Then rely on the adjustment of the control and regulation system to balance the fluctuation of the post-valve pressure with the spring force, so that the post-valve pressure remains constant within a certain error range. The disadvantage of the existing pressure fl...
