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.

摘要： The invention relates to a device for regulating the flow rate and/or pressure of a fluid, such as valve for a pressure gas cylinder, comprising a reducing valve including a first plug designed to be moved in the normal flow direction of the fluid during closure. The reducing valve also comprises a plunger to which the plug is coupled. The face of the plunger that is oriented towards the first plug defines a regulation chamber together with the body. The aforementioned face also comprises a seal that engages with a corresponding surface of the body such as to form a second plug for maintaining residual pressure. The regulation device also comprises a means for preloading and releasing a spring acting on the opposite face of the plunger.

摘要： A method for calculating the remaining usage time of a gas cylinder equipped with a pressure reducer, the method comprising the following steps: (a) measuring the pressure of the gas in the cylin-der; (b) calculating the variation of pressure of the gas in the cylinder over time while gas is out-putted; (c) calculating a remaining usage time Tr based on the measured pressure in the cylinder and the calculated variation of pressure. Step (c) takes into account characteristics of the pressure reducer relative to variations of its nominal flow rate along the decrease of its inlet pressure while emptying the cylinder.
