ABSTRACT:
A gas regulator with a double pressure adjusting function has a valve body closed with a lower valve lid with two round gas chambers formed in the valve body and the valve lid, each gas chamber having a gas pressure adjuster to adjust pressure of incoming gas. A pressure controller is combined in a gas exit hole of the valve body to block immediately the gas exit hole in case of abnormal gas pressure flowing through the gas exit hole, and a gauge is provided near a gas intake of the valve body to check pressure of gas flowing in the first gas chamber.
