Abstract
A valve may include a valve seat and may include a primary ball sized and positioned to seal against the valve seat when the valve is in a closed state. A valve may additionally include a secondary ball sized and positioned to apply a force against the primary ball to facilitate the sealing of the primary ball against the valve seat when the valve is in the closed state. A valve may include a valve seat that may tilt relative to a longitudinal axis of the valve.
Claims20
A valve, comprising:
- a valve seat;
- a primary ball sized and positioned to seal against the valve seat when the valve is in a closed state;
- a secondary ball sized and positioned to apply a force against the primary ball to facilitate sealing of the primary ball against the valve seat when the valve is in the closed state;
- and
- a cage having the primary ball and the secondary ball located therein, the cage configured to contain the primary ball and the secondary ball within the valve and to allow fluid flow through the valve past the primary ball and the secondary ball when the valve is in an open state.
A valve, comprising:
- a ball;
- a cage having the ball located therein, the cage configured to contain the ball within the valve and to allow fluid flow through the valve past the ball when the valve is in an open state;
- and
- a valve seat sized and configured to receive the ball and provide a seal between the valve seat and the ball when the valve is in a closed state, the valve seat configured to tilt relative to a longitudinal axis of the valve.
A method of restricting fluid flow with a valve, the method comprising:
- positioning a primary ball against a valve seat;
- and
- applying a force to the primary ball in a direction that is non-parallel with a longitudinal axis of the valve with a secondary ball.
