Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of check valves, in particular to an anti-clogging check valve. Background Art
[0002] A check valve is a valve with a circular disc as the opening and closing part. It is an automatic valve that blocks the backflow of the medium by its own weight and the pressure of the medium. It is also called a non-return valve, a one-way valve, a reflux valve or an isolation valve. The check valve is often used as a bottom valve of a pumping device to prevent the backflow of water. The check valve is used in combination with a stop valve to achieve safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.
[0003] When the existing check valve is used in places with poor working environment, due to the large amount of impurities contained in the liquid medium, it is easy to be blocked by solid impurities mixed in the liquid after long-term use, which will cause the valve gate to get stuck and the check valve needs to be disassembled for repair, which is very inconvenient. For this reason, we propose an anti-blocking check valve. Utility Model Content
