Description

Technical Field

[0001] The utility model relates to the technical field of filter pressure reducing valves, and particularly relates to a filter pressure reducing valve which is convenient to clean. Background Technique

[0002] A filter pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through adjustment and relies on the energy of the medium itself to automatically keep the outlet pressure stable. From the perspective of fluid mechanics, a filter 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, so as to achieve the purpose of pressure reduction. Then, 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 remains constant within a certain error range, and the water flow is filtered while passing through the filter pressure reducing valve.

[0003] When the existing filter pressure reducing valve is in use, in order to ensure the sealing performance of the valve body, the connection between the various structural components of the valve body is usually very firm, making it difficult to disassemble the valve body. The internal filter device will accumulate dirt after long-term use, and it will be relatively difficult for people to clean the valve body. In order to solve the deficiencies of the existing technology, we propose a filter pressure reducing valve that is convenient to clean. Content of the Utility Model
