Background technology
Modern common (portable) fire extinguisher is with steel cylinder storage high pressure fire-suppressant gas, with gas itself or accompany by fire-fighting powder, when fire takes place, manually pushes handgrip, with leverage, discharges steel cylinder inner high voltage gas fast, and high speed is sprayed the fire extinguishing source.This class fire extinguisher, light, quick, inexpensive, the fire extinguishing air velocity is fast, good extinguishing effect.It is fire splendid Fire extinguisher commonly used of effect when just sending out.Personnel's instrument does not have human factor but this class fire extinguisher is just put out a fire, and fire extinguisher is just useless.
Automatic Fire Extinguisher is the main body of fire extinguishing, and machine is responsible, and not slack, this is the strong point of machine.But the judgement of machine on the whole,, handle fire flexibly ability not as manpower.
Classic automatic fire extinguishing system is the glass marble automatic sprinkler system, explodes when fire burns glass marble, and the water under certain hydraulic pressure sprays from burning fried glass marble, reaches the purpose of fire extinguishing.This system pipe network complex structure, the cost height the more important thing is that its response time is long, glass marble must be burnt to explode, the fire system of will causing disaster could work.
A kind of " visiting the fire tube automatic fire extinguisher " arranged now, is the high-pressure extinction gas with steel cylinder, passes through the protected area by one " spy fire tube ".When burning broken " spy fire tube ", fire-suppressant gas overflows and reaches the fire extinguishing purpose.This extinguishing device structure is simplified greatly, and it is long that shortcoming is still the response time; Must be broken with visiting the fire tube burning, and burn the not inevitable directionality of tool of tear, bring uncertainty for the effect of putting out a fire.The advantage of these two kinds of fire extinguishers (system) is: utilize the energy of fire to start the release of firing-fighting medium automatically, do not have the anxiety of misoperation extremely.When fire will cause disaster, also there is not the anxiety of tripping work, problem is that the fire system of will the causing disaster risk of just working is too big.
