Corrugated pipe ball valve

The invention belongs to the field of valves, and discloses a corrugated pipe ball valve which comprises a valve body, a valve ball and a valve cover, a containing cavity is formed in the valve body, the valve ball and the valve cover are located in the containing cavity, a communicating cavity is formed in the middle of the valve ball, the valve body is provided with an inlet, an outlet and a mounting opening which are connected with the containing cavity, and the valve cover is arranged outside the mounting opening. And the valve cover is connected with the mounting port in a sealing manner. Through the combination of the corrugated pipe and the scraping part, in the opening and closing process of the ball valve, the scraping part is used for cleaning the valve ball, the smoothness of the outer surface of the ball valve is kept, and it is ensured that the ball valve can be normally conducted under the working condition with dust, and stable sealing can be achieved when flow is cut off. The combination of th
