More Information
Summary:The utility model belongs to the technical field of ball valves, in particular to a leakproof ball valve which comprises a valve body, a ball core assembly and an extrusion mechanism, the ball core assembly comprises a ball core and a rubber layer, the rubber layer is of a spherical shell structure and wraps the outer side of the ball core, the valve body is of a spherical shell structure, and the extrusion mechanism is arranged on the valve body. Two end pipes are symmetrically arranged on the outer side of the valve body in a communicating mode, the ball core is located in the valve body, and the outer side wall of the rubber layer is bonded with the inner side wall of the valve body. Through the arrangement of the rubber layer and the extrusion mechanism, a gap between the ball core and the valve body is conveniently blocked, abrasion caused by contact between the ball core and the valve body or a gap between the ball core and the valve body due to quality problems are avoided, meanwhile, after the ball co
