The specific embodiment
For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, the utility model is done further detailed explanation below in conjunction with the accompanying drawing and the specific embodiment.
With reference to Fig. 1-3; A kind of down-hole lifesaving appliance comprises the deflation structure of gas in the air bag 1 being emitted behind air bag 1, gas generator 2 and the intact air bag 1 to be used, on said gas generator 2, is provided with the steam vent 3 of a plurality of exhausts in air bag 1; Said gas generator 2 is positioned at air bag 1; Comprise two reative cells 5 that separate through isolated gate 4, on said isolated gate 4, have one can rip the opening 7 that part or is blocked by cork 6, said part or the cork 6 ripped connects one and draws back structure 8; The said structure 8 of drawing back is passed and is located at reative cell 5 sidewalls and air bag 1 wall reaches outside the air bag 1; 3 places are provided with one way valve 9 at said steam vent, and one way valve 9 can not arrive in the air bag 1 the unreacted medium of reative cell 5, and the gas of generation is got back to reative cell 5.
Operating principle is: draw back structure 8; Ripped part on the isolated gate 4 or cork 6 are torn; Go thereby make reaction medium hybrid reactions in two reative cells 5 produce gas and be charged to the air bag 1 from steam vent 3, because this structure is drawn back and can be ripped part or cork 6 just can make the medium reaction, pneumatic structure is opened simply; Therefore save inflationtime, be applicable to burst accident.According to test, adopt suitable reaction medium, can reach 0.25 second with the weak point of this device inflationtime.
