摘要 |
<p>The invention pertains to apparatus for making up fluid connections in association with an underwater wellhead structure. The apparatus comprises a pair of matable bodies including a female body having a generally laterally inwardly facing wall defining a receptacle and a male body adapted for insertion into and removal from the receptacle by movement in a generally longitudinal directional mode. The male body has a generally laterally outwardly facing wall for disposition adjacent the wall of the female body when the male body is inserted therein. Each of the bodies has a respective fluid passageway, and each of these passageways has a port opening through the laterally facing wall of the respective one of the bodies, the two ports being generally in register when the bodies are matingly engaged. A check valve is disposed in the port of one of the bodies, the check valve being biased to a position closing the respective port and having an actuator movable in a generally lateral directional mode to open said port.</p> |
