Title:
VALVE FOR CRYOGENIC LIQUID GAS
Document Type and Number:
WIPO Patent Application WO/2020/222420
Kind Code:
A1
Abstract:
The present invention relates to a valve for a cryogenic liquid gas and, more specifically, to a valve provided in a use line (a gas use line and a liquid use line) of a storage tank for liquid helium or liquid hydrogen which is a cryogenic liquefied gas having a temperature less than or equal to the critical temperature of -253℃, to control a fluid flow. Particularly, the present invention relates to a valve for a cryogenic liquid gas, which has an improved structure to prevent the valve from coming into a non-operational state due to freezing or performance degradation of the valve due to a repetition of expansion and contraction in cryogenic circumstances.
