摘要： A locking door assembly, blowout preventer and method are provided. The blowout preventer is for sealing about a tubular extending from a wellbore of a wellsite. The blowout preventer includes a housing having a bore and a channel therethrough. The tubular is positionable through the bore and engageable therein. The blowout preventer also includes a door assembly including a door slidably positionable along an axis of the channel and providing selective access to the channel, and a lock. The lock includes at least one locking member having at least one raised portion extending along the door assembly in a direction transverse to the axis of the channel. The locking member is extendable into at least one corresponding receptacle of the housing and movable therealong between an unlocked and a locked position whereby the door assembly is selectively retractable from the housing.

摘要： A wellsite connector (110) includes a connector body (232) having an end adapted for coupling to a first of the components and a cavity (265) to receive a second of the components, a piston (234) axially movable in the connector body and having a piston profile along an inner surface thereof, and a plurality of collets (236). The collets are positionable about the connector body adjacent the piston and radially movable thereabout. The collets have a collet profile along an outer surface thereof corresponding to the piston profile of the piston. The collets also have a grip profile along an inner surface thereof selectively engageable with the second of the components whereby the collets are selectively latchable about the second of the components.

摘要： A lock assembly of a blowout preventer is provided. The blowout preventer includes a ram assembly slidably positionable in the channel and engageable with a tubular. The ram assembly includes a ram block, a ram cylinder, and a ram shaft. The lock assembly includes a lock cylinder and a lock piston. The lock cylinder is operatively connectable to the ram cylinder. The ram shaft has an end slidably extendable into a lock cavity of the lock cylinder. The lock piston is slidably positionable in the lock cylinder and separates the lock cavity into a lock and a closing chamber. The lock piston has a ram surface engageable with the end when the lock piston is in a locked position, and a ram hole therethrough to receive the end when the lock piston is in an unlocked position whereby the ram block is selectively lockable about the tubular.
摘要翻译：提供防喷器的锁组件。防喷器包括可滑动地定位在通道中并与管状物接合的柱塞组件。柱塞组件包括柱塞块，柱塞缸和柱塞轴。锁组件包括锁芯和锁活塞。锁芯可操作地连接到压头缸。柱塞轴具有可滑动地延伸到锁芯的锁定腔中的端部。锁定活塞可滑动地定位在锁芯中，并将锁定腔分离成锁和闭合室。锁定活塞具有当锁定活塞处于锁定位置时与端部接合的冲头表面，以及当锁定活塞处于未锁定位置时通过该冲头孔接收该端部的冲头孔，由此该压头块可围绕管状物选择性地锁定。
