Cryogenic Fluid Cylinder

摘要

A cryogenic fluid cylinder includes an inner vessel for holding cryogenic fluid, a cylindrically shaped outer vessel having a vertical longitudinal axis surrounds the inner vessel and forms an insulating space there between, and operating controls located on a top of the outer vessel. Customer or end user operating controls include a liquid-use valve for selectively dispensing liquid cryogen, a pressure-building valve for selectively controlling a pressure building circuit, and a gas-use valve for selectively dispensing cryogen gas. Supplier or maintenance personnel operating controls include an economizer regulator for selectively setting at least one desired pressure of the inner vessel, a vent valve for selectively venting cryogen fluid, and a vacuum pressure port for indicating vacuum pressure between the vessels. The end user controls are located on a front side of the outer vessel while the supplier controls are located on a rear side of the outer vessel.

1. A cryogenic fluid container comprising, in combination:
an inner vessel for holding cryogenic fluid; a cylindrically shaped outer vessel having a vertically extending central longitudinal axis and surrounding the inner vessel and forming an insulating space therebetween; end user operating controls located on a top of the outer vessel including a liquid-use valve for selectively dispensing liquid cryogen from the inner vessel, a pressure-building valve for selectively controlling a pressure building circuit for increasing pressure within the inner vessel, a gas-use valve for selectively dispensing gaseous cryogen from the inner vessel; and wherein each of the end user operating controls are located on a front side of the top of the outer vessel.
