Description
Technical field
The utility model relates to the extinguishing device technical field, is specifically related to for stopping or put out burning or the blast at the flammable explosive gas initial stages such as methane, the automatic fire extinguisher that avoids greater disaster.
Background technology
Automatic fire extinguishing system is in recent years to be applied to oil field oil storage tank, refueling station, contain deathtrap, flammable explosive gas chemical plant, the safety device of the combustion explosion at the deathtrap initial stages such as coal containing methane gas ore deposit, its operation principle is: produce when there is initial flame the deathtrap of containing flammable explosive gas, Artificial Control or use sensor sensing send signal to control module to flame, control module outputs signal to automatic fire extinguisher, the igniting of gas generator in the device produces gases at high pressure moments extinguishing chemical dry powder in will install and sprays, in the initial flame position and around form the dry powder of foot, end and put out initial burning things which may cause a fire disaster.
The defective that existing automatic fire extinguisher exists is:
1. in order immediately to break through, and sealing, barrier film adopts plastic foil substantially, thickness is limited, in use because sharp objects enters nozzle or collision, easily break barrier film, powder is made moist in dry powder can, lump, when automatic fire extinguisher in when normal operation, high-pressure gas pressure discharges nowhere and makes the dry powder can blast;
2. nozzle is short, and jet length is limited, and range limited (about 5 meters) is for the place that the ask for something range is far away inapplicable (more than 8 meters).
The utility model content
Technical problem to be solved in the utility model is to improve a kind of simple in structure, the automatic fire extinguisher of the far firing range that dusts.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of automatic fire extinguisher, comprise the powder extinguishing agent tank, the lengthening jet pipe that is connected with the powder extinguishing agent tank port of export consists of, it is characterized in that: be provided with extinguishing chemical dry powder and gases at high pressure slowly-releasing tank in the described powder extinguishing agent tank, be provided with gas generator shell in the described gases at high pressure slowly-releasing tank, described gas generator shell one end is provided with the combustion gas delivery outlet, described powder extinguishing agent pot bottom is connected with bottom, described gases at high pressure slowly-releasing tank and gas generator shell link to each other with the king-bolt that is welded on bottom central authorities by screw thread, described gas generator shell bottom leads to ignition circuit, described ignition circuit is connected with cable, described gas generator shell middle part cover has combustion gas cool metal screen pack, and described lengthening jet pipe ejection end margin is connected with protective door by the jet pipe connecting axle.
Described bottom is that circular flange links to each other with powder extinguishing agent pot bottom flange by bolt.
Described combustion gas cool metal screen pack is the annulus cylindrical shell that steel wire is pressed into.
Described combustion gas delivery outlet is the crown cap of the even perforate in top, links to each other by the outer silk of internal thread and gas generator shell.
Described extinguishing chemical dry powder is that ABC powder extinguishing agent is in bulk in the powder extinguishing agent tank.
Be provided with the isolating seal film between described lengthening jet pipe flange in the bottom and the powder extinguishing agent tank top flange.
Described isolating seal film is the antistatic rubber film.
Described protective door is comprised of the semicircle thin-walled door of two fans, and at its binding site, a fan shirt rim is lower, and a fan shirt rim is upper, and is closed by closure stack shirt rim.
The beneficial effects of the utility model are:
1. it is easily impaired that the utility model has solved existing automatic fire extinguisher protective separation film in some adverse circumstances; cause the powder extinguishing agent caking that makes moist; device receive fire extinguishing during signal gases at high pressure smoothly release can cause whole device explosion; form the defective of larger harm; the utility model by before jet pipe, arrange protective door can the protective separation film in order to avoid it is impaired in complex environment; simultaneously; can open under less pressure because the protective door design is light, can not affect the dry powder jeting effect.
2. jet pipe lengthens, about 10 centimetres of general jet pipe axial lengths, about 5 meters of ranges, the utility model jet pipe extends to more than 20 centimetres, be equivalent to prolong the accelerating length of bullet in gun barrel, the utility model has increased the range that dusts (more than 8 meters), is necessary for the remote position of putting out a fire of ask for something.
