Abstract
The utility model discloses a double-seal ball valve, which relates to the field of ball valves and comprises a valve seat, a ball body is arranged in the valve seat, a valve rod matched with the valve seat is arranged at the top end of the ball body, first external threads are arranged on the outer side of the top of the valve rod, and an adjusting rod is arranged on the outer side of the first external threads. A sealing assembly matched with the inner wall of the middle of the valve seat is arranged at the bottom of the valve rod. A sealing piece matched with the inner wall of the bottom of the valve seat is arranged on the outer side of the ball body, the top end of the sealing assembly is sleeved with an installation lantern ring matched with the valve rod, and second external threads matched with the inner wall of the valve seat are arranged on the outer side of the installation lantern ring. Under the combined action of the sealing assembly and the sealing piece, double sealing between the ball body and the valve seat is achieved, the sealing performance after the ball valve is closed is improved, the stability of fluid control is guaranteed, the service life of equipment is prolonged, and the safety and reliability of operation are improved.
