Abstract
A valve including a flow control assembly having an adaptive, floating closure member is provided. In one embodiment, a ball valve includes a floating closure member having a shoulder enclosed within a recess of the valve body. The recess is larger than the shoulder of the closure member and allows axial movement of the closure member with respect to the valve body and along a flow path through the valve. Additional valve systems, devices, and methods are also disclosed.
Claims15
A valve comprising:
- a body;
- a flow control assembly inside the body, the flow control assembly including a ball, a seat carried by the ball, and a closure member, wherein the seat is installed in the body in a manner that allows movement of the seat toward and away from the ball, the closure member is installed in the body in a manner that allows movement of the closure member with respect to the body and along a flow path through the valve, and the seat and the closure member have mating sealing surfaces that seal against each other when the valve is closed.
A method comprising:
- receiving fluid in a valve disposed between first and second sections of a fluid conduit, the valve including a valve body and a flow control assembly inside the valve body, wherein the flow control assembly includes a ball, a seat carried by the ball, and a closure member;
- rotating the ball to a closed position within the valve body in which the seat seals against the closure member, wherein the seat is installed in the valve body in a manner that allows movement of the seat toward and away from the ball, the closure member is installed in the valve body in a manner that allows movement of the closure member with respect to the valve body and along a flow path through the valve, and rotating the ball to the closed position causes pressure of the fluid to apply a net force on the seat that pushes the seat against the closure member.
