Abstract

A cryogenic storage tank system and an automatic flow path selector valve for the same, in which maintenance is more convenient, the length of pipes is minimized, and the pressure of liquefied gas in a gaseous phase inside a cryogenic storage tank is automatically adjusted.

Description

technical field [0001] The present invention relates to a technology related to a cryogenic storage tank system in which a gas having a very low boiling point, such as nitrogen or natural gas, can be stored, and more particularly, the present invention relates to a technology by which, The pressure of the liquefied gas in the gas phase within the cryogenic storage tank system can be automatically adjusted. Background technique [0002] When transporting or storing a gas with an extremely low boiling point, the gas is kept in a liquefied state, and for this purpose cryogenic storage tanks are utilized. Typically, cryogenic storage tanks are surrounded by insulating material that inhibits heat transfer. However, a part of the liquefied gas stored in the cryogenic storage tank evaporates naturally because it is impossible to completely prevent heat transfer. As a result, a certain part of the liquefied gas exists in a gas phase, which is called flash gas (hereinafter, referre...
