According to the present invention, an automatic flow path conversion valve for a liquefied gas storage tank having an ultra-low temperature includes: a valve main body having a first liquid phase inlet into which a liquid phase liquefied gas flows, a second gas phase inlet into which a gas phase liquefied gas flows, a first gasification outlet through which the liquefied gas is discharged to a main vaporizer on the outside, and a second return outlet through which the liquid phase liquefied gas is discharged to the outside; and a flow path conversion member converting to i) a boost mode, ii) a liquid phase discharge mode, or iii) a decompression mode according to the pressure applied to the first liquid phase inlet and the pressure applied to the second gas phase inlet. |
