Description

Technical Field

[0001] The utility model relates to the field of valves, and in particular to an anti-blocking valve. Background Art

[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief.

[0003] In the prior art, there is an anti-blocking valve with application number CN202221396320.X. In the above scheme, "the clean inner scraper drives the inner shaft to rotate, and as the clean inner scraper rotates, the water flow can be moved to the port of the water outlet pipe to flow out... When the valve needs to be closed, just turn the knob, and when the knob contacts the inner shaft, it can be fixed, so that the valve can be closed." However, the valve needs to be in operation most of the time. During long-term operation, the clean inner scraper will rub against the inner wall of the valve body. Long-term friction can easily cause the clean inner scraper to wear. After the clean inner scraper is worn, the sealing performance will be greatly reduced, affecting the sealing performance of the valve. How to invent an anti-blocking valve to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content
