气体填充和分配装置以及包括这种装置的组件
摘要：
本发明公开一种气体填充和分配装置，包括用于放置于加压气体贮存容器的孔中的体部、在用于与容器(30)的内部相连的上游第一端和用于与气体使用者(40)相连的下游第二端之间延伸的气体回收回路(20)，该回收回路(20)包括按照从上游端到下游端的顺序串联布置的压力调节器(50)、低压室(70)和隔离阀(60)，低压室(70)与一通路(80)连接，该通路用于通过安全卸压阀(5，6，8，18，19，21)将气体排放至装置外部，安全卸压阀对低压室(70)内的压力敏感并且被设计成，当低压室(70)内的压力低于第一阈值时关闭排放通路(80)，当低压室(70)内的压力高于第一压力阈值且低于第二压力阈值时打开排放通路(80)，以及当低压室(70)内的压力高于第二压力阈值时关闭排放通路(80)。
摘要（英）：

Device for filling and distributing gas comprising a body intended to be placed in the orifice of a pressurized-gas storage reservoir, a gas withdrawing circuit (20) running between an upstream first end intended to be connected to the inside of the reservoir (30) and a downstream second end intended to be connected to a user (40) of the gas, the withdrawing circuit (20) comprising a pressure regulator (50), a low-pressure chamber (70) and an isolation valve (60) positioned in series in that order from upstream to downstream, the low-pressure chamber (70) being connected to a passage (80) for discharging the gas to the outside of the device via a safety relief valve (5, 6, 8, 18, 19, 21) sensitive to the pressure in the low-pressure chamber (70) and designed to close off the discharge passage (80) when the pressure in the low-pressure chamber (70) is below a first threshold, to open the discharge passage (80) when the pressure in the chamber (70) is higher than the first pressure threshold and below a second pressure threshold, and to close the discharge passage (80) when the pressure in the chamber (70) is higher than the second pressure threshold.
