摘要

A closure (10) includes a hub (12) having a bore (14) in fluid communication with the port (5) of a vessel (7). A door (22) is removably positioned within the bore (14) of the hub (12), and a locking ring (28) is threaded with the hub thread (16) for moving the door (22) to a closed and circumferentially sealed position against the shoulder (24). At least one rotatable actuator element, such as a plurality of gears (32), engages the locking ring (28) and is rotated to rotate the locking ring. A breaker bar or impact wrench could be used to rotatable drive the actuator elements.
