Abstract
A plug that contacts both an upstream seat and a downstream seat based on a upstream spring creating first forces on the upstream seat and a downstream spring creating second forces on the downstream seat. The first forces may be in a downstream direction and the second forces may be in an upstream direction. Additionally, the upstream chamber and the downstream chambers may be dependent pistons that are configured to create dynamic forces acting upon the plug.
Claims18
A high pressure valve for oil and gas operations comprising:
- a plug configured to rotate between an open position and a closed position, wherein in the open position the plug allows fracturing fluid to flow through tubing, the plug being configured to move along a linear axis when in the closed position;
- a first assembly positioned upstream from the plug, the first assembly including a first seat positioned upstream from the plug and configured to contact the plug, the first seat being configured to move along the linear axis based on receiving forces from the plug, the first assembly including a first chamber configured to generate a first force against the first seat;
- a second assembly positioned downstream from the plug, the second assembly including a second seat positioned downstream from the plug and configured to contact the plug, the second seat being configured to move along the linear axis based on movement of the first seat and receiving forces from the plug, the second assembly including a second chamber configured to generate a second force against the second seat;
- a conduit directly extending from the first chamber to the second chamber, wherein fluid flows through the conduit to control the first force and the second force responsive to movement of the plug on the linear axis and the first seat or second seat receiving the forces from the plug, wherein the first force is inversely related to the second force.
A high pressure valve comprising:
- a plug configured to rotate between an open position and a closed position, wherein in the open position the plug allows fracturing fluid to flow through tubing;
- a first assembly positioned upstream from the plug, the first assembly including a first seat positioned upstream from the plug and configured to contact the plug, the first seat being configured to move along a first linear path;
- a second assembly positioned downstream from the plug, the second assembly including a second seat positioned downstream from the plug and configured to contact the plug, the second seat being configured to move along the first linear path based on movement on the first seat;
- a conduit that is configured to allow fluid communication between the first chamber and the second chamber, the conduit extending across the plug;
- an external piston in fluid communication with the conduit, the external piston including a first side and a second side, the first side being configured to receive the fracturing fluid to move the external piston.
A method associated with a high pressure valve comprising:
- rotating a plug from an open position to a closed position, wherein in the open position the plug allows fracturing fluid to flow through tubing;
- positioning a first assembly upstream from the plug, the first assembly including a first seat positioned upstream from the plug and configured to contact the plug;
- moving the plug along a liner axis while in the closed position;
- moving the first seat along the linear axis, the first assembly including a first chamber configured to generate a first piston force against the first seat;
- positioning a second assembly downstream from the plug, the second assembly including a second seat positioned downstream from the plug and configured to contact the plug;
- and
- moving the second seat along the linear axis based on movement on the first seat and based on receiving forces from the plug, the second assembly including a second chamber configured to generate a second piston force against the second seat;
- moving fluid through a conduit to control the first force and the second force responsive to movement of the plug on the linear axis and the first seat or second seat receiving the forces from the plug, wherein the first force is inversely related to the second force, wherein the conduit directly communicating coupling the first chamber and the second chamber.
