Three-way ball valve

The invention relates to the technical field of valves, in particular to a three-way ball valve. The three-way ball valve comprises a pipeline, a valve handle, a ball valve body, a water flow passage, a first opening, a second opening and a third opening. The side, far away from the third opening, of the water flow passage in the ball valve is in an arc shape, and a protective net is mounted in the ball valve. The side, far away from the third opening, of the protective net is fixedly connected with a supporting spring. According to the three-way ball valve, when liquid flows into the water flow passage, bubbles in the liquid break on the surface of the protective net; and then the supporting spring supports the protective net to cooperate with the protective net, so that the purpose of preventing the bubbles from being broken on the side wall of the water flow passage is achieved, and the situation that shock waves generated by bubble breaking damage the inner wall of the ball valve is prevented; and meanwhi
