Recovery Valve |
| 摘要 |
A tubing hanger landing system includes a tubing hanger running tool, a locking flowline to lock the tubing hanger running tool into a tubing hanger, and a lower body shear joint comprising a recovery valve. The recovery valve includes a valve body with a functional port, an operational port, a bi-directional port, and a relief port, and a valve piston positioned within the valve body and movable between an operational position and a relief position within the valve body. The functional port enables pressure to be communicated to the valve piston to move the valve piston from the operational position to the relief position, and, in the relief position, the valve piston provides fluid communication through a relief flowpath between the bi-directional port and the relief port to release pressure from the locking flowline. |

1. A tubing hanger landing system, comprising:
a tubing hanger running tool; a locking flowline to lock the tubing hanger running tool into a tubing hanger; and a lower body shear joint comprising a recovery valve, the recovery valve comprising:
a valve body comprising a functional port, an operational port, a bi-directional port, and a relief port; anda valve piston positioned within the valve body and movable between an operational position and a relief position within the valve body;wherein the functional port enables pressure to be communicated to the valve piston to move the valve piston from the operational position to the relief position; andwherein, in the relief position, the valve piston provides fluid communication through a relief flowpath between the bi-directional port and the relief port to release pressure from the locking flowline. |
