The utility model has following good effect than prior art.A kind of liquid of the present utility model draws the pressurizer of cigarette system to adopt the air pressure spray regime to take double reductor simultaneously, and decompression step by step is more accurate and more stable through the two-stage decompression delivery pressure; Adopt the carbon fiber composite gas cylinder, it has the operation pressure height, and filling often, and is in light weight, and the advantage that gas-storing capacity is big can effectively prolong the performance machine and draw the cigarette Show Time; Pressure reducer is provided with safety valve and opens pressure accordingly, has guaranteed the structural safety in fumicants cabin; Set up an air cock, the effect of air cock is to bleed off gas cylinder and the pressure gas that draws in the cigarette gondola when ground service is safeguarded; Before air cock, also set up a tee connection, carried out ground and when safeguarding, can connect compression indicator and observe and draw supercharging pressure in the cigarette gondola, take down this compression indicator during the aircraft Heaven, the stifled blocking cap of going up had so both maintained easily use, had solved the nervous problem in aircraft installation site again.
Description of drawings
Fig. 1 is the scheme drawing that a kind of liquid of the present utility model draws the pressurizer of cigarette system.
The specific embodiment
Fig. 1 is that a kind of liquid of the present utility model draws the pressurizer of cigarette system.It is characterized in that: by gas filled device, gas cylinder 4, supercharging combine valve 5, pressure purger is formed, gas filled device one end can be connected with the ground inflatable appliance, the other end is connected with gas cylinder 4, gas cylinder 4 and supercharging combine valve 5 one end UNICOMs, supercharging combine valve 5 other ends connect pressure purger, pressure purger is linked the control setup 9 that liquid draws the cigarette system again, described gas filled device is by gas-charging connection 1, inflation combine valve 2, compression indicator 3 is formed, gas-charging connection 1 one ends are connected with the ground inflatable appliance, the other end connects inflation combine valve 2, inflation combine valve 2 is connected on the gas cylinder 4 by compression indicator 3, and described pressure purger is made up of one-level pressure reducer 6 and second depressurized device 7.After the ground inflatable appliance was connected with gas-charging connection 1 on the machine, opens inflation combine valve 2, high pressure gas charged into gas cylinder 4 through compression indicator 3, observe by compression indicator 3, when the pressure in the gas cylinder 4 reaches 11.8MPa～12.7MPa, close inflation combine valve 2, promptly finish inflation to pressurizer.Manual unlocking supercharging combine valve 5, gas cylinder 4 inner high voltage gases are through supercharging combine valve 5, one-level pressure reducer 6, second depressurized device 7, one-level pressure reducer delivery pressure is 0.6MPa～1.5MPa, second depressurized device delivery pressure is 0.5MPa～0.55MPa, and is more accurate and more stable through the two-stage decompression delivery pressure.When aircraft need be performed, by drawing cigarette control setup 9, after selecting to draw the cigarette color, high pressure gas with in the fumicants holding bay draw fumicants to be delivered to be contained in engine high-temperature air-flow place draw the cigarette nozzle, through nozzle ejection, draw fumicants in thermal current, to form smog under certain temperature.
