Top-mounted semi-ball valve with filtering function

According to the technical scheme, the top-mounted semi-ball valve with the filtering function is characterized by comprising a valve body, a valve seat positioned in the valve body, a valve element capable of abutting against the valve seat and a valve rod driving the valve element to rotate. The valve element comprises a cut-off part used for cutting off medium circulation and a circulation part located on one side of the cut-off part and used for allowing media to pass through, the circulation part is detachably connected with a conical filtering assembly, the tip end of the filtering assembly extends into an inner cavity of the cut-off part, and a connecting rod used for being connected with the tip end of the filtering assembly is arranged on the inner wall of the cut-off part. The problems that a filter screen in the prior art is prone to damage, short in maintenance period and complex in operation are solved. 本实用新型公开了一种具有过滤功能的上装式半球阀，其技术方案要点是包括阀体、定位于阀体内的阀座、能与阀座顶触的阀芯和带动阀芯转动的阀杆，阀芯包括有用于切断介质流通的切断部和定位于切断部一侧且
