Description

Technical Field

[0001] The utility model belongs to the technical field of pressure reducing valves, and relates to a pressure reducing valve, in particular to a new type of pressure reducing valve. Background Art

[0002] A 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 maintain the outlet pressure stable. From the perspective 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, 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.

[0003] At present, the water inlet end of the pressure reducing valve on the market lacks a filtering structure, resulting in low water quality of the incoming water flow. There are impurities in the water, and the impurities directly impact the inside of the valve. After a long time, the internal structure is damaged, affecting the use. Summary of the Invention

[0004] The purpose of the utility model is to provide a new type of pressure reducing valve that can be quickly disassembled and assembled for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of pressure reducing valve includes a valve body with a water inlet end, and is characterized in that a filtering component is arranged on the water inlet end. The filtering component is composed of a filter net and a filtering skeleton. A clamping component is arranged on the water inlet end. The clamping component is composed of a clamping block and a return spring. A clamping groove matching with the clamping block is opened on the filtering skeleton relative to the clamping block. The clamping groove divides the filtering skeleton into a clamping part and a connecting part. An unlocking device is arranged between the connecting part and the inner wall of the water inlet end. An activity space for the unlocking device to move is opened between the connecting part and the inner wall of the water inlet end.

[0006] In the above-mentioned new type of pressure reducing valve, an inclined part is arranged on the clamping block, and a lifting protrusion is arranged on the inner wall of the filtering skeleton.

[0007] In the above-mentioned new type of pressure reducing valve, a limiting part is arranged on the inner wall of the water inlet end.

[0008] Compared with the prior art, the utility model newly sets a filtering component, which has the advantages of good filtering effect and improved service life, and the filtering component can be quickly installed or disassembled through the clamping device and the unlocking device, making the later replacement more convenient.
