Working procedure of the present utility model:
1, oxygen supply process: high pressure oxygen P1 after filtration element 19 enters the hyperbaric chamber X of decompressor valve seat group 5, and arrive low-pressure cavity Y by valve platform 501, then arrive low-pressure cavity Z by guiding valve group 7, now pressure reduces to P2.Gas in low-pressure cavity Z exports to the control gear of Portable positive pressure automatic resuscitator by meeting mouth I.Gas in low-pressure cavity Z by connect mouth II export directly connect oxygen therapy face shield to have the wounded of autonomous respiration implement oxygen therapy relief.The adjustable output gas flow of gas meeting mouth II of rotation hand wheel 10, selects suitable flow gear according to the different demands of the wounded.
2, decompression process: when high pressure oxygen gas pressure decline and P1 reduce, guiding valve group 7 will be caused under the effect of pressure regulator spring 6 to move to handwheel 10 direction, valve platform 501 is increased with the gap of valve core of the spool valve, and height presses through tolerance and becomes large, makes the instantaneous elevated exits pressure remained steady of middle pressure.
In the middle of calm the anger press when rising and P2 increases time, will cause guiding valve to move to spanner direction, valve platform 501 is reduced with the gap of valve core of the spool valve, height presses through that tolerance is instantaneous to diminish, the instantaneous decline of middle pressure, so the stablizing of guarantee delivery pressure.
In the middle of calm the anger and press through up to during to the unloading pressure of safety valve, unloading opened by safety valve, plays safety protection effect.
Low-pressure cavity Z communicates with low-pressure cavity Y, and the change of the gas pressure therefore in low-pressure cavity Z is synchronous with low-pressure cavity Y, and the moment keeps outlet pressure to stablize.
