The invention discloses a flow display control device for an aircraft oxygen system, which comprises a shell, and a cavity B and a cavity D are arranged at the lower end of the shell and are respectively connected with an air inlet pipeline and an air outlet pipeline; a cavity C is formed in the upper end of the cavity D, and the cavity B is communicated with the cavity D through the cavity C; a flow limiter is arranged at the communicated part of the upper end of the cavity D and the cavity C; a mounting cavity is formed in the portion, above the cavity B, of the shell, a cap is assembled on the mounting cavity, a pressure sensing diaphragm, a pressing ring and an indicating gasket are arranged below the cap, and the pressure sensing diaphragm is arranged at the bottom of the mounting cavity and can expand upwards when the interior of the pressure sensing diaphragm is pressed. The circumference of the pressure sensing diaphragm is fixedly sealed through a pressing ring. The indication gasket is installed above the pressing ring, the indication gasket is of a circular structure made of rubber, and a cross-shaped notch is formed in the indication gasket; wherein the lower portion of the pressure sensing diaphragm is a cavity E, a cavity F is arranged between the cap and the pressure sensing diaphragm, the cavity E is communicated with the cavity C through a hole channel, and the cavity F is communicated with the cavity D through a hole channel.
