The invention discloses an aircraft multi-gas-cylinder centralized oxygen supply system, a high-pressure oxygen filling end of an oxygen cylinder assembly is communicated with an oxygen filling port through a first oxygen filling pipe, a second four-way connector, a third oxygen filling pipe, a first four-way connector and a second oxygen filling pipe, and during oxygen filling, after ground oxygen filling equipment is in butt joint with the oxygen filling port, the oxygen cylinder assembly can be filled with oxygen; the low-pressure oxygen supply end of the oxygen bottle assembly is communicated with a sixth oxygen supply pipe through a first oxygen supply pipe, a first oxygen supply tee joint, a second oxygen supply pipe, an oxygen supply cross joint, a third oxygen supply pipe, a fourth oxygen supply pipe and a fifth oxygen supply pipe, and oxygen at the low-pressure end in the oxygen bottle assembly is connected together in series. Oxygen in the oxygen bottle assembly is supplied to the unit and passengers through a second oxygen supply pipe; the pressure relief end of the oxygen bottle assembly communicates a high-pressure protection valve and a release valve on the oxygen bottle assembly through a pressure relief branch pipe, a pressure relief four-way joint and a pressure relief header pipe; and once the gas in the oxygen bottle assembly exceeds the limit pressure value specified by the design, safe pressure relief is carried out.
本发明公开了一种飞机多气瓶集中供氧系统,氧气瓶组件的高压充氧端通过第一充氧管、第二四通接头、第三充氧管、第一四通接头、第二充氧管与充氧口连通,充氧时,将地面充氧设备与充氧口对接后就可以为氧气瓶组件充氧;氧气瓶组件的低压供氧端通过第一供氧管、第一供氧三通、第二供氧管、供氧四通、第三供氧管、第四供氧管、第五供氧管和第六供氧管连通,将氧气瓶组件内的低压端氧气串联到一起,供氧时,氧气瓶组件内的氧气通过第二供氧管为机组及旅客供氧;氧气瓶组件的泄压端通过泄压支管、泄压四通、泄压总管将氧气瓶组件上的高压保护阀与泄放阀连通;一旦出现氧气瓶组件内气体超过设计规定的极限压力值时进行安全泄压。
