ABSTRACT:
A gas regulator provided with a leakage detecting device, which is adopted for depressurizing the supplied gas and detecting a leakage in the gas system. Above the pressure-reducing chamber of a conventional gas regulator the present leakage-detecting device is installed which is fixedly secured to the upper cap thereof. A sensing rack member of the present detecting device is disposed above and bears against a reinforcement plate and is actuated to move up and down along with a diaphragm associated with the reinforcement plate as a result of the gas pressure in the pressure-reducing chamber of the present regulator as well as the acting force of an pressure-adjusting spring so that gas leakage can be accordingly indicated thereby.
