Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figures 1 to 4, Portable positive pressure automatic resuscitator decompressor, including link 1, sealing ring 2, connector 3, alignment pin 4, valve seat group 5, pressure regulator spring 6, guiding valve group 7, quantity control valve 8, determining hole sheet 16, high voltage U-shaped card 17, Pressure gauge 18, pressure tapping 1801, filter element 19, jump ring 20, spanner 21, spanner 22, connecting line 23, described valve seat group 5 includes valve platform 501 and fastening cap 502；Described guiding valve group 7 includes piston 701 and spool 702；Described link 1 is connected with connector 3 by alignment pin 4, and described sealing ring 2 is arranged between alignment pin 4 and connector 3, equipped with spanner 21 and the spanner 22 that connected by connecting line 23 on described link 1；Connector 3 is connected with valve seat group 5 by alignment pin 4, is provided with connector 3 in the front end of described filter element 19, and described filter element 19 is fixed by jump ring 20；Wherein: it also includes sealing ring 2, valve body group 9, handwheel 10, clamping back-up ring 11, packing ring 12, place kick 13, location spring 14, spigot joint II15, being provided with relief valve in described valve body group 9, described relief valve includes safety-valve 901, safety valve spring 902 and safety valve cap 903；
Described valve seat group 5 is connected with valve body group 9 by screw, and the front end of valve seat group 5 is equipped with valve platform 501, and described valve platform 501 is fixed by fastening cap 502, equipped with sealing ring 2 between valve platform 501 and valve seat group 5；The side of described valve seat group 5 is equipped with Pressure gauge 18 and spigot joint I24, and pressure tapping 1801, spigot joint I24 are connected by U-shaped card with valve seat group 5 and pass through sealing ring 2 and seal；Equipped with spigot joint II15 outside valve body group 9, have hole 25 with spigot joint II15 junction in valve body group 9, between safety-valve 901 and valve body group 9, be provided with sealing ring 2；It is provided with guiding valve group 7 between valve seat group 5 and valve body group 9, between guiding valve group 7 and valve seat group 5, is provided with pressure regulator spring 6 and sealing ring 2；Quantity control valve 8 one end is located in valve body group 5, the other end is fixed with handwheel 10 by screw, have 11 dosing holes 26 in the main body of quantity control valve 8 to connect with the hole that the spigot joint II15 junction in valve body group 9 is opened, between quantity control valve 8 and valve body group 9, be provided with sealing ring 2；Place kick 13, location spring 14 it is provided with between described valve body group 9 and handwheel 10.
The work process of the present invention:
1, oxygen supply process: high pressure oxygen P1 enters the high pressure chest X of decompressor valve seat group 5 through filter element 19, arrives low pressure chamber Y by valve platform 501, arrives low pressure chamber Z again through guiding valve group 7, and now pressure reduces to P2.Gas in low pressure chamber Z is exported to the control device of Portable positive pressure automatic resuscitator by spigot joint I.Gas in low pressure chamber Z directly connects oxygen therapy face shield to there being the wounded of autonomous respiration to implement oxygen therapy relief by spigot joint II output.The output gas flow of gas of the spigot joint II of rotation hand wheel 10 scalable, 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, to cause that under the effect of pressure regulator spring 6 guiding valve group 7 moves to handwheel 10 direction, the gap making valve platform 501 and valve core of the spool valve increases, and height presses through tolerance and becomes big, makes the instantaneous elevated exits pressure remained steady of middle pressure.
In the middle of calm the anger when pressing liter and when P2 increases, will cause that guiding valve moves to spanner direction so that the gap of valve platform 501 and valve core of the spool valve reduces, height presses through that tolerance is instantaneous to diminish, the instantaneous decline of middle pressure, stablizing of such guarantee output pressure.
In the middle of calm the anger and press through up to during to the unloading pressure of relief valve, unloading opened by relief valve, plays safeguard protection effect.
Low pressure chamber Z communicates with low pressure chamber Y, and therefore the change of the gas pressure in low pressure chamber Z is Tong Bu with low pressure chamber Y, and the moment keeps outlet pressure stable.
