Abstract
A closure (10) for sealing fluid within a pressure vessel having a hub (70) with an opening therein includes a door (12) and a plurality of clamp ring segments (14) for fitting over an exterior portion of both the closed door and the hub. A plurality of interconnecting members (18) connect ends of adjacent clamp ring segments, and an actuator mechanism (20) moves the plurality of clamp ring segments into and out of engagement with the door.
Claims20
A closure for sealing fluid within a pressure vessel having the hub with an opening therein, the closure comprising:
- a door for fitting over the opening in the hub and having a central axis;
- a plurality of circumferentially spaced clamp ring segments for fitting over an outer exterior portion of both the closed door and the hub;
- a plurality of interconnecting members for connecting ends of adjacent clamp ring segments;
- and
- an actuator mechanism rotatable about the central axis of the door for moving each of the plurality of clamp ring segments into and out of engagement with the door.
A closure for sealing fluid within a pressure vessel having the hub with an opening therein, the closure comprising:
- a door for fitting over the opening in the hub and having a central axis;
- a plurality of clamp ring segments supported on the door for fitting over an outer exterior portion of both the closed door and the hub;
- a plurality of interconnecting members for connecting ends of adjacent clamp ring segments;
- and
- an actuator mechanism rotatable about the central axis of the door for moving each of the plurality of clamp ring segments into and out of engagement with the door, the actuator mechanism including a plurality of radially extending members each interconnected to a respective one of the plurality of clamp ring segments.
