ABSTRACT:
A gas-regulating unit for regulating an internal gas pressure in a gas-tight liquid-storage tank is mounted on the gas-tight tank in which stored liquid is sealed from outside atmosphere by covering a top surface of the stored liquid with an isolating-gas. The gas-regulating unit includes a main gas-exhausting unit and an isolating-gas regulator. The main gas-exhausting unit includes an exhaust valve for opening and exhausting gases from the gas-tight tank when an internal gas pressure in the gas-tight tank increases to more than a specified level. The isolating-gas regulator supplies the isolating-gas when an isolating-gas pressure decreases to less than a specified level. The main gas-exhausting unit and the isolating-gas regulator are integrally coupled with each other.
