Wellhead connector with release mechanism |
摘要 |
A wellhead connector comprises a tubular main body movably mounting a set of circumferentially spaced members for radial extension and retraction. An actuator on the main body is operatively associated with the members to radially extend them. Levers are interengaged between the main body and the members, when the latter are extended, and are operative to at least partially retract the members.
