Abstract
A storage and delivery device for a cryogenic liquid that includes a vessel assembly and a delivery line assembly. The vessel assembly has a liquid space and a vapor space. The delivery line assembly has a liquid line, a vapor line, and a delivery line. The liquid line is in fluid communication with the liquid space. The vapor line is in fluid communication with the vapor space. The liquid line has a flow control device located thereon and structured to control the flow of fluid through the liquid line. The liquid line flow control device is structured to close the liquid line when the vessel assembly is at a predetermined pressure.
Claims14
A storage and delivery device for a cryogenic liquid comprising:
- a vessel assembly having a liquid space and a vapor space;
- a delivery line assembly having a liquid line, a vapor line, and a delivery line;
- said liquid line in fluid communication with said liquid space, said vapor line in fluid communication with said vapor space;
- said liquid line having a flow control device located thereon and structured to control the flow of fluid through said liquid line;
- wherein said liquid line flow control device is structured to close said liquid line when said vessel assembly is at a predetermined pressure;
- said vapor line having a flow control device located thereon and structured to control the flow of fluid through said vapor line;
- and
- wherein said vapor line flow control device is structured to open only when said liquid line flow control device is closed.
