Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valves, in particular to an adjustable pressure reducing valve. Background Art

[0002] A pressure reducing valve adjusts the inlet pressure to a preset outlet pressure through its own mechanical components, automatically maintaining a stable outlet pressure by relying on the energy of the medium itself. Pressure reducing valves can be categorized by structure as diaphragm, piston, or bellows. They can also be classified by operating mode as direct-acting, reverse-acting, unloading, or auxiliary valve types.

[0003] In application number: CN201921292857.X, an adjustable pressure reducing valve is disclosed. By rotating the threaded rod, the position of the valve core inside the connecting cavity can be controlled, and the degree of opening between the valve core and the connecting cavity can be adjusted, thereby controlling the size of the water flow, that is, the water pressure of the water discharged from the drainage pipe can be adjusted. The adjustment is flexible and easy to use. The bottom of the valve bottom cavity is detachably connected to the valve bottom cover by fastening bolts, replacing the existing integrated structure of the pressure reducing valve. The valve bottom cover can be easily removed to inspect and clean the interior of the valve body, thereby improving the service life of the pressure reducing valve. However, the above design still has shortcomings. A handle is provided at the top of the valve body, and the valve body is controlled by turning the handle. However, some staff with weak hands find it inconvenient to operate the handle, which makes it inconvenient to use the pressure reducing valve.

[0004] To this end, we propose an adjustable pressure reducing valve. Utility Model Content
