| description | The utility model relates to the technical field of fuel gas supply equipment, in particular to an intrinsically safe self-closing gas outlet valve which comprises a valve body, a valve head assembly and a piston assembly. The valve body is provided with a gas channel, the valve body is provided with a gas inlet port and a gas outlet port, the valve head assembly comprises a first spring and a valve head plug, the piston assembly comprises a second spring and a gas blocking plug, and in the intrinsically-safe self-closing gas outlet valve, when the intrinsically-safe self-closing gas outlet valve is not used, the second spring pushes the gas blocking plug to seal the gas channel so as to prevent gas leakage; when the air outlet port is externally connected with an air return gun, the air return gun pushes the first ejector rod to move towards the second spring, the second spring is compressed by the air blocking plug, then the air channel is opened, and the problems that a traditional self-closing valve is si |
