Description

Technical Field

[0001] This utility model relates to the field of pressure reducing valve technology, and more specifically, to a filter pressure reducing valve with a quick-replaceable filter screen. Background Technology

[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a desired outlet pressure by adjustment, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From a fluid mechanics perspective, a pressure reducing valve is a throttling element with variable local resistance; that is, by changing the throttling area, the flow velocity and kinetic energy of the fluid are altered, resulting in different pressure losses, thereby achieving the purpose of pressure reduction.

[0003] However, most current filter pressure reducing valves are not convenient for replacing the filter screen, thus reducing their convenience. Furthermore, most of them do not have a delivery function, which reduces their practicality. Utility Model Content
