Gas Bottle Valve Provided With A Flywheel Controlling A Residual-Pressure Valve And A Stop Valve

摘要

The invention relates to a valve for a gas cylinder pressure. It includes a body with a gas inlet, a gas outlet and a gas passage connecting the net to the outlet. The valve comprises a residual pressure holding disposed at the gas passage. It also comprises a valve for closing the gas passage downstream of the residual pressure holding. A flywheel control valve acts on the valve and on the holding device via a residual pressure control rod and, respectively. The steering wheel includes sliding tracks for the control rods. It comprises a first position of the bottle filling device where the residual pressure holding is turned off and the valve is open, a second dosed position of the bottle where the holding device is active residual pressure valve and is closed, and a third operative position where the holding device is active residual pressure and the valve is opened.
