The invention belongs to the technical field of airborne oxygen systems, and particularly relates to a flow control device applied to an oxygen system. The flow control device comprises an inlet connecting nozzle, a lower cavity shell, a valve seat, a spring, a valve rod, a hard core, a fixing ring, a diaphragm, an upper cavity shell, a first outlet connecting nozzle, a second outlet connecting nozzle and the like. Compared with a traditional metering hole flow control mode, under the condition that it is guaranteed that the total output flow meets the rear end requirement, consumption of the total oxygen amount when the inlet pressure is too high is reduced. One outlet end outputs gas flow which is continuously reduced along with the increase of the inlet pressure, and one outlet end outputs increased gas flow to the rear end along with the increase of the inlet pressure. Therefore, the two output ends can be flexibly applied to different scenes, and the flow can be selectively output according to the requir
