Abstract
The presnt disclosure relates to passively rotating a valve using fluid flow. Some aspects may involve a valve including a body, a lower stem, and vanes. The body may include a bottom portion that can be positioned with respect to a seat for preventing fluid flow when the valve is in a closed position. The lower stem may extend axially from the bottom portion of the body to position the bottom portion with respect to the seat. The vanes may extend from the body and be responsive to the fluid flow while the valve is in an open position such that the valve and the lower stem rotate with respect to the seat.
Claims20
A valve comprising:
- a body with a bottom portion positionable with respect to a seat for preventing fluid flow in a closed position of the valve;
- a lower stem extending axially from the bottom portion to position the bottom portion with respect to the seat;
- and
- at least one vane extending from the body for responding to fluid flow in an open position of the valve to cause the valve and the lower stem to rotate with respect to the seat.
A valve assembly, the valve assembly comprising:
- a valve movable between an open position and a closed position, the valve including a seal;
- a seat positionable with the seal to prevent fluid flow in the closed position;
- a lower stem extending from a bottom portion of the valve for aligning the seal with the seat;
- and
- at least one vane extending from the valve for responding to the fluid flow to cause the valve and the lower stem to rotate with respect to the seat.
A method comprising:
- moving a valve including a seal, a lower stem extending axially from a bottom portion of the valve, and at least one vane to an open position at which fluid flows between the seal and a seat;
- rotating the valve and the lower stem with respect to the seat using energy from the fluid contacting the at least one vane;
- and
- moving the valve to a closed position at which the seat cooperates with the seal and prevents the fluid flowing between the seat and the seal.
