ABSTRACT:
Provided is a hydrostat for a portable gas range, which prevents the explosion of a gas container by automatically discharging overcompressed gas from the gas container when the inner pressure of the gas container increases to an explosion pressure. The hydrostat includes a body including a gas outlet, which communicates with a gas inlet of the governor valve, and a sealed room, which communicate with the gas outlet. An opening/closing unit is installed within the sealed room of the body such that it can elastically move up and down in order to discharge overcompressed gas by opening the gas outlet when the inner pressure of the gas container reaches or exceeds a threshold value of deformation. A cap is fixed at the bottom of the body so as to support the opening/closing unit and has a discharge hole for discharging overcompressed gas, which escapes the gas container through the gas outlet.
