Abstract
In a gas-cylinder valve adapted to be mounted onto a gas cylinder for use there are provided a gas supply valve chamber and a protection valve chamber in sequence between a gas inlet and a gas outlet within a valve box of the gas-cylinder valve. The gas supply valve chamber is provided with a gas supply valve body and the protection valve chamber is provided with a protection valve body. When the gas outlet of the gas-cylinder valve is opened to the atmosphere, the protection valve body serves to prevent ambient air, and moisture and/or dust in it from entering the gas supply valve chamber thereby avoiding damage to the valve and leakage of gas from the valve.
