Below in conjunction with accompanying drawing, survival capsule malleation of the present invention being maintained to system is described further.
Fig. 1 is the structural representation that survival capsule malleation of the present invention maintains system.
Fig. 2 is catenation principle figure of the present invention.
In figure: 1 is closed cabin body, 2 is compressed air bottle, and 3 is stop valve, 4 is the first reducing valve, and 5 is bus-bar, and 6 is shuttle valve, 7 is tertiary filter, and 8 is the second reducing valve, and 9 is the first ball valve, 10 is noise damper, 11 is relief tube exhaust opening, and 12 is the second ball valve, and 13 is one way valve, 15 is high pressure gauge, and 16 is low-pressure meter.
The specific embodiment
As Fig. 1, shown in Fig. 2, survival capsule malleation of the present invention maintains system, comprise closed cabin body 1, pressure relief system in ftercompction system and cabin in cabin, in cabin, in ftercompction system and cabin, pressure relief system is installed in the inside of closed cabin body 1, in cabin, ftercompction system is by compressed air bottle 2, stop valve 3, the first reducing valve 4, shuttle valve 6, tertiary filter 7, the second reducing valve 8 and the first ball valve 9 form, stop valve 3 is installed on compressed air bottle 2, compressed air bottle 2 is communicated with an air inlet port of shuttle valve 6 by high pressure flexible metallic conduit, the first reducing valve 4 is installed on the high pressure flexible metallic conduit between compressed air bottle 2 and shuttle valve 6, another air inlet port of shuttle valve 6 is connected with the outside that high pressure flexible metallic conduit leads to closed cabin body 1, the gas outlet of shuttle valve 6 is connected with one end of tertiary filter 7, the other end of tertiary filter 7 is provided with the second reducing valve 8 and the first ball valve 9 successively,
In cabin, pressure relief system is comprised of relief tube exhaust opening 11, the second ball valve 12, one way valve 13, the outside that relief tube exhaust opening 11 is arranged on the bulkhead of closed cabin body 1 and closed cabin body 1 is stretched out in one end, one end that relief tube exhaust opening 11 is positioned at closed cabin body 1 inside is provided with the second ball valve 12 and one way valve 13 successively.
