Connecting apparatus for conveyance of cryogenic fluid |
摘要 |
A connecting apparatus for conveyance of cryogenic fluid has a pair of connecting members formed of thermal insulating material. Each has a flange with an axial tubular protrusion and a rim extending over the protrusion so as to form an annular cavity therebetween. Each flange and its protrusion has a central bore. When the two members are fitted together, the combined bore conveys of cryogenic fluid therethrough. The protrusions have overlapping lips with a snug fit to substantially retain the cryogenic fluid in the combined bore. A detachable retainer holds the members in union with an o-ring seal between the rims. The respective cavities form an enclosed cavity that provides thermal insulation between the ring seal and the tubular protrusions for the cryogenic fluid in the common bore.
