Anti-scouring, high-temperature-resistant and corrosion-resistant ball valve

The ball valve comprises a valve body, a valve seat is arranged in an inner cavity of the valve body, a ball body is arranged in the middle of the valve seat, an annular clamping ring is tightly clamped in an inner cavity of an annular clamping groove, a hemispherical net is fixedly connected to the right portion of the annular clamping ring, and annular sliding openings are formed in the upper portion and the lower portion of the outer wall of the ball body. The ceramic ball valve is made of ceramic materials, the ceramic materials have the characteristics of corrosion resistance, scouring resistance, abrasion resistance and the like, the hemispherical metal net is arranged in the valve body and can play a role in buffering water entering from the water inlet, then scouring with the ball body is reduced, meanwhile, the hemispherical net is in a net shape, and therefore the service life of the ball valve is prolonged, and the service life of the ball valve is prolonged. In addition, the auxiliary valve can be
