Referring to Fig. 1, in the utility model embodiment, a kind of aero tyre dynamic gas pressure system, including pipeline 8, it is described
Pipeline 8 is provided with 4, is connected between adjacent pipeline 8 by threeway 1, and 8 outer end of pipeline of left and right ends is also equipped with threeway 1,
The pipeline 8 of right end is connected with filter 10 by threeway 1, and steel card 2 is provided with the pipeline 8 of left end, and the quantity of steel card 2 is set on demand
Put, steel card 2 is in order to which pipeline 8 is fixed on babinet, and pressure controller 3 is provided with second threeway 1 of left end, left end
Solenoid valve 5 is provided with 3rd threeway 1, relay 4 is electrically connected between the pressure controller 3 and solenoid valve 5, it is described
Transformer 6 is also electrically connected with solenoid valve 5, pressure reducer 7 is provided with the 4th threeway 1 of left end, is set in the threeway 1 of right end
It is equipped with shut-off valve 9.
When to the tyre inflating of aircraft nose wheel, the gases at high pressure in gas cylinder, by filter 10, shut-off valve 9, subtract
After pressure valve 7, the gas pressure in gas cylinder is down to 350Psi by 3000psi.Then the gas of inflation system is with 350Psi's
Pressure is by solenoid valve 5, pressure controller 3, by valve connector to tyre inflating.Due to before this by pressure controller 3
Upper and lower limit pressure value be adjusted to 174 ~ 176Psi, therefore when the air pressure in tire reaches 174 ~ 176Psi, intelligent digital pressure
