Abstract:
The invention relates to a mechanical energized sealing ball valve comprising a seat, a ball assembly, and a single valve stem that operates both the sealing member and the ball. The ball comprises a ball and a sealing member. The valve stem drives the ball to rotate between open position and close position. When the ball reaches the close position, the sealing member, operated by the same valve stem, moves away from the ball to press and sit against the seat. The invention has the advantages that: the valve has a compact structure, the friction-free on/off is achieved, the mechanical energized sealing force is even and reliable, the ball is retracted and locked in the opening position to protect against turbulence-induced damage, low operating torque, the open/close operation is rapid, and the valve stem seal operates simply and reliably.

Claim (Index 4):
The ball valve of  claim 1 , wherein the first valve stem is mechanically coupled to the ball by means of a spring.
