Abstract
Apparatus for connecting together flowlines including separately actuated gripping and sealing assemblies which are actuated by hydraulic pressure but are held in actuated positions utilizing internally mounted mechanical-type mechanisms.
Claims21
Apparatus for connecting together flowlines, comprising:
- a generally cylindrical housing having a first end for connection to a first flowline and having a bore therethrough, said generally cylindrical housing having a second, open end to receive a second flowline in said bore;
- a generally cylindrical gripping means mounted within said bore for receiving said second flowline member, said gripping means being movable radially inwardly into gripping engagement with said second flowline;
- camming means mounted within said housing bore in engagement with said gripping means for moving said gripping means into gripping engagement with said second flowline in response to relative movement between said camming means and said gripping means;
- gripper actuator means mounted within said housing bore for axial movement from an initial to an actuated position in engagement with said gripper means to effect relative movement between said gripping means and said camming means to move said gripping means into gripping engagement with said second flowline;
- grip position lock means mounted in said housing bore in engagement with said gripper actuator means for locking said gripper actuator means in said actuated position;
- a generally cylindrical sealing means mounted within said housing bore for radial expansion in response to axial compression to seal between said second flowline and said housing bore;
- seal actuator means which is generally cylindrical and mounted wihtin said housing bore for axial movement from an initial to an actuated position in sufficient engagement with said seal means to axially compress said sealing means to effect a seal between said second flowline and said housing bore;
- seal position lock means mounted in said seal actuator means in engagement with said gripper actuator means for locking said seal actuator means in said actuated position;
- and
- fluid actuator means for using pressurized fluid to move said grip actuator means and said seal actuator means to said actuated position.

- said gripper actuator means being a generally cylindrical grip actuator piston mounted within said housing bore for movement between initial and actuated positions and includng a grip actuating end positioned in engagement with said gripping means;
- said grip position lock means including means for continuously engaging said generally cylindrical grip actuator piston for preventing return of said piston member from said actuated position;
- said grip position lock means further includes a generally cylindrical lock member positioned between said grip actuator piston and said housing bore and having a circumferential recess therein with;
- a plurality of ratchet members mounted in said circumferential recess;
- and
- resilient elements are mounted within said circumferential recess of said generally cylindrical lock member in engagement with said ratchet members to resiliently urge said ratchet members into engagement with said grip actuator piston.
