The utility model discloses a steel-plastic composite type wear-resistant ball valve which comprises a valve body, ball seats are connected to the two ends of the valve body, a metal ball core is movably connected between the ball seats, the metal ball core is connected with a valve rod driving the metal ball core to rotate, the metal ball core is provided with a material through hole, a wear-resistant layer is arranged on the inner wall of the material through hole, and the wear-resistant layer is arranged on the inner wall of the material through hole. And a material through hole polishing layer is arranged on the wear-resistant layer. According to the steel-plastic composite type wear-resistant ball valve, the metal ball core provided with the wear-resistant layer and the material through hole polishing layer is used for effectively improving the anti-scraping capacity of the ball core to impurities, reducing the friction force of a circulation pipeline in the valve body, preventing impurity accumulation a
