Ball valve ripple spring valve seat seal mechanism

The utility model relates to a ball valve ripple spring valve seat seal mechanism. Including valve body, valve rod, spheroid, disk seat and drive mechanism, the disk seat is ripple spring disk seat, valve rod one end is connected with the spheroid, and the valve rod other end is connected with drive mechanism, place in the valve body in the ripple spring disk seat, the cooperation is hugged closely with ripple spring disk seat mutually to spheroidal surface, the valve body upper end is equipped with valve gap and valve body fixed connection, ripple spring disk seat has elasticity, the interior terminal surface of ripple spring disk seat is equipped with the spacer and hugs closely the cooperation mutually with the spheroid. The utility model discloses simple structure, manufacturing process is simple, through adopting ripple spring disk seat, has solved the loaded down with trivial details technology that adopts the welding installation disk seat in traditional ball valve, effectively solves the disk seat and produces in the part with spheroidal sealed face and leak the phenomenon, has improved the sealing performance of valve greatly, and the spacer can effectively block the impurity in the medium.
