[0011] 2. The wedge-type compensating ball valve that prevents misoperation can filter and collect impurities in the fluid passing through the wedge-type compensating ball valve in time. When the fluid flows from one side of the valve body to the reserved groove, the fluid will enter between the partition and the filter plate along the guide layer on one side of the support frame, and continue to flow after contacting and filtering the filter plate. At this time, the impurities intercepted by the filter plate will be temporarily stored in the collection chamber on one side of the partition. The wedge-type compensating ball valve that prevents misoperation can filter and collect impurities inside the fluid, thereby improving the functionality of the wedge-type compensating ball valve when in use.
