Abstract

The invention discloses a high-reliability floating hard-seal ball valve, and relates to the field of pipeline valves. The high-reliability floating hard-seal ball valve comprises a valve body, a valve seat, a ball body and a sealing performing improving piece; a first accommodating space and a first flow channel passing through the first accommodating space are arranged in the valve body; the valve seat is arranged in the first accommodating space; the valve seat is internally provided with a second accommodating space and a second flow channel passing through the second accommodating space;the second flow channel communicates with the first flow channel; the ball body is rotationally arranged in the second accommodating space; the second accommodating space is matched with the ball bodyin shape; a third flow channel used for communicating with the second flow channel is arranged in the ball body; and the sealing performance improving piece is used for separately acting on the valvebody and the valve seat and providing an acting force facing the ball body for the valve seat. The high-reliability floating hard-seal ball valve has the advantages that the sealing performance is improved, and the service life is prolonged.
