Description
Technical field
What the present invention relates to is a kind of device of security against fire technical field, specifically is a kind of fire extinguishing jet device.
Background technology
International at present, domestic employed foam fire-fighting equipment, as: foam annihilator, sump pressure formula foam proportioning unit, foam vehicle etc., generally all adopt the foam fire-fighting blowing agent to mix by a certain percentage with water, pass through mechanical foaming, form the air of certain multiple, sprinkling covers on the comburant, the fire extinguishing initial stage, after the air bubble expanded by heating fragmentation in the foam, moisture in the bubble has been taken away certain heat when the vaporization evaporation on the one hand, the air that overflows in the opposing party's papula mixes with combustible substance, forms burning more at a certain temperature, because constantly additional foam, make that burning decreases with former calory burning again, incremental continuous cooling makes burning not continue, and reaches cooling at last, the purpose of isolated fire extinguishing.
Find through retrieval prior art, Chinese patent literature CN101190364A, an open day 2008-6-4 put down in writing a kind of " the fiery equipment of high expansion foam ", and this technology relates to makes the fire foam that contains surfactant be blended in the water the also injection nozzle of the soaked solution of force feed; Be built-in with this injection nozzle and by discharge the channel cylinder that above-mentioned soaked solution attracts the air in the discharging area from above-mentioned injection nozzle; Be arranged in the above-mentioned channel cylinder and produce net with the foam of the above-mentioned soaked solution collision of discharging from above-mentioned injection nozzle.But this technology has following defective: high expansion foam is when effectively putting out a fire, and foam bubble fills the air in the whole protecting space, does not almost have visual space, has a strong impact on personnel activity and evacuation.In addition, situation complexity in the tunnel, personnel are numerous in the vehicle, and the old and weak people, women and children all has, and high expansion foam may cause the sick young personnel's of part the old and the weak breathing problem.Therefore, should not be used for the tunnel self-extinguishing.
Chinese patent literature CN101461988A, open day 2009-6-24 has put down in writing a kind of " multifunctional balancing application valve ", and this technology comprises valve body of main valve, change valve, valve core of main valve, reversing valve core, black box etc.By control piper guide pressure medium, make this novel valve possess pressure balance and control keying function simultaneously.But this technology has following defective: this mixer structure complexity, and anemostat need be set, thereby dwindle the fluid bore, the device fire-fighting efficiency with bore is reduced.
Chinese patent literature CN201026362Y, Granted publication day 2008-2-27, put down in writing a kind of " a kind of combined framework type sprinkler tip ", this technology comprises a body that is connected with fire protection pipeline, one splash box that water is gushed equably, one is loaded on the screw that is used for fixing temperature-sensing element and black box on the splash box, and it also comprises a plurality of pillars, and splash box and stiffener are supported on the body.Adopt a kind of connection the in riveted joint, screw thread, the welding manner between pillar and body and splash box and the stiffener.But this technology has following defective: at first be that the water flowing aperture is little, single interior injection flow rate of shower nozzle unit interval does not reach the tunnel fire requirement.Secondly, the current that this shower nozzle sprays do not nebulize, and spray regime is little, and the effect of the dangerous fire of putting out a fire to save life and property is bad.Once more, this shower nozzle comes injection water by the explosion of temperature-sensing element temperature-sensitive, because airflow complexity in the tunnel, it is the perception point of origin accurately, specific aim fire extinguishing weak effect.Should not be used for tunnel fire.
Find by retrieval in addition, this type of device that Shanghai Golden Shield Fire Safety Equipment Co produces, wherein the foams mix mode is to adopt the balanced type foam proportioner.This mixer structure complexity need be provided with anemostat, thereby has dwindled the fluid bore, and the device fire-fighting efficiency with bore is reduced.In addition, this device is not saved oneself and is coiled out liquid systems, can only foam fire hydrant box be set in addition or place some tool dry powder extinguishers for first aid usefulness.Once more, shower nozzle that this device is with is one-sided axial shower nozzle, forms at land side and sprays the blind area; The fuel tank position of more dangerous is general automobile is all on the right side of vehicle, in case automotive oil tank catches fire, because of can not get putting out a fire timely and effectively, consequence will be hardly imaginable.Also be to spray the blind area below protected object, in case the vehicle bottom is on fire, loss also will be very big.At last, owing to do not have the foam solution flushing hole on the device, the high etching problem that remains in the inner foam solution of associated conduit and device can't be resolved, and may cause heavy corrosion, the breaking-up of relevant pipeline and device.
