Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking valve bodies, in particular to a valve with an anti-blocking structure. Background Art

[0002] Valves are control components in pipeline fluid delivery systems, used to change the cross-section of the passage and the flow direction of the medium. They have functions such as diversion, cut-off, throttling, check, diversion or overflow pressure relief.

[0003] During the use of the valve, in order to prevent the valve from being blocked, a pipe filter is usually installed at the water inlet end of the valve to prevent impurities from blocking the valve. This includes a blue filter. When replacing the filter screen of the pipe filter, it is necessary to open the top cover of the filter. The filter screen is fixedly connected to the top cover by a connecting rod, and the top cover is moved to remove the filter screen. However, when replacing the filter screen, unfiltered water can easily flow from the water inlet end to the water outlet end and enter the valve, affecting the use of the valve. In order to prevent water from the water inlet end from flowing into the water outlet end when replacing the filter screen, a valve with an anti-blocking structure is provided. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting a blocking mechanism, the top cover is moved upward, and the movement of the top cover drives the filter element to move. The fixed ring pushes the movable ring to move upward through the clamping block. The movable ring moves upward to block the water inlet and the water outlet. The fixed protrusion contacts the lower pressure ring and pushes the lower pressure ring to move. The clamping block moves into the movable ring and separates from the fixed ring. Then the filter element continues to move out of the filter seat and the filter element is cleaned. This makes it easy to automatically block the water inlet and the water outlet when cleaning the filter element to prevent unfiltered water from flowing into the valve through the outlet.
