Abstract
Embodiments of the present disclosure are directed towards a back pressure valve configured to mount in a mineral extraction system. The back pressure valve includes a body comprising a venting port coaxial with a longitudinal axis of the body, a plunger configured to be in sealing engagement with the body to seal the venting port, and a lock ring disposed about the body, wherein the lock ring is configured to automatically expand radially upon removal of a tool.
Claims20
A system, comprising:
- a back pressure valve configured to mount in a mineral extraction system, wherein the back pressure valve comprises:
- a body comprising a venting port coaxial with a longitudinal central axis of the body;
- a plunger configured to be in sealing engagement with the body to seal the venting port;
- and
- a lock ring disposed about the body, wherein the lock ring is configured to automatically expand radially upon removal of a tool.
2 more elements
A method, comprising:
- coupling a retrievable tool to a back pressure valve, wherein the back pressure valve comprises a plunger configured to create a first sealing interface with a venting port of the back pressure valve, wherein the venting port is coaxial with a longitudinal central axis of the back pressure valve;
- landing the back pressure valve within a mineral extraction system component via linear translation of the retrievable tool and the back pressure valve;
- and
- automatically radially expanding a lock ring of the back pressure valve upon removal of the retrievable tool from the back pressure valve.
1 more element
A system, comprising:
- a mineral extraction system component;
- a back pressure valve configured to be disposed within the mineral extraction system component, comprising:
- a body comprising a venting port, wherein the venting port is coaxial with a longitudinal central axis of the body;
- a plunger configured to be in sealing engagement with the body to seal the venting port;
- and
- a lock ring disposed about the body;
- and
- a retrievable tool configured to couple to the back pressure valve and linearly translate the back pressure valve into a landed position within the mineral extraction system component,
- wherein the lock ring is configured to automatically expand radially upon removal of the retrievable tool from the back pressure valve.
