[0002] A ball valve is a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can be used for fluid regulation and control. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in pipelines. It only needs to rotate 90 degrees and a very small torque to close tightly. Ball valves are most suitable for use as switches and cut-off valves.

[0003] Currently, a Chinese patent with the announcement number CN212616461U discloses an anti-clogging ball valve, which includes a ball valve body, a connecting cylinder extending through the middle of the upper end surface of the ball valve body, a valve stem movably installed inside the connecting cylinder, and a sealing ball valve ball inlaid on the end of the valve stem. The sealing ball valve ball fits the interior of the ball valve body. However, in the above patent, when cleaning the filter, the sealing screw cylinder needs to be rotated and disassembled, which is more cumbersome when cleaning the filter and reduces the flexibility when cleaning the filter. Therefore, in order to solve the above problems, we provide an anti-clogging ball valve. Utility Model Content
