Abstract
A fill port and apparatus for a cryogenic container includes a static gland having an internal cavity and a cryogenic seal surrounding an outlet, the outlet connected to the cryogenic container. A mechanical gland connected to a source of cryogenic fluid is sealingly positioned in the cavity of the static gland. The mechanical gland is arranged to be positionable within the static gland into a fill, or alternately, a seal position wherein in the fill position, cryogenic fluid flows through the mechanical gland into the cryogenic container through the outlet. Positioning the mechanical gland in the seal position causes the mechanical gland to engage the cryogenic seal isolating the cryogenic container from the outlet.
Claims20
A fill port for a cryogenic container comprising:
- a static gland having an internal cavity and a cryogenic seal surrounding an outlet, the outlet connected to the cryogenic container;
- and
- a mechanical gland connected to a source of cryogenic fluid sealingly positioned in the cavity of the static gland, the mechanical gland arranged to be positionable within the static gland between a fill position wherein cryogenic fluid flows through the mechanical gland into the cryogenic container through the outlet and a seal position wherein the mechanical gland engages the cryogenic seal isolating the cryogenic container from the outlet and wherein the mechanical gland includes a fill tube connected to the source of cryogenic fluid and to a set of openings, the openings extending through a ceiling of the mechanical gland.
An apparatus for filling a cryogenic container comprising:
- a static gland having a cylindrical exterior wall having screw threads formed on the static gland exterior wall and an internal cavity having a cryogenic seal surrounding an outlet, the outlet connected to the cryogenic container;
- a mechanical gland having a fill tube connected to a source of cryogenic fluid, the mechanical gland includes a portion of the mechanical gland sealingly positioned in the cavity of the static gland;
- and
- a tightening nut having an interior space defined by a cylindrical interior wall that has screw threads formed on the interior wall and an opening located on a top surface of the tightening nut, wherein the fill tube extends through the opening, placing another portion of the mechanical gland in the tightening nut interior space,
- wherein the tightening nut is arranged to be rotated in a first direction to engage the tightening nut screw threads to the static gland screw threads and position the static gland into a fill position wherein cryogenic fluid flows through the mechanical gland into the outlet and the cryogenic container.
