Description
Technical field
The present invention relates to a kind of portable fire extinguisher, specially one kind can be exported water mists with constant pressure and can be realized
The fire extinguisher of water mists and extinction using gas switching double-purpose.
Background technology
Conventional hand fire extinguisher includes dry powder extinguisher, foam annihilator and carbon dioxide extinguisher now.Wherein,
Inorganic salts dry powder class extinguishing medium is filled in dry powder extinguisher, fire-fighting principle includes the starvation and asphyxia of physical principle
Flame is put out a fire, and the chemically suppression combustion reaction free radical and active group of principle, interrupts combustion flame.Foam fire-fighting
Filled and process type extinguishing medium in device, sprayed using foam nozzle pressure and produce a large amount of foams, combustion is covered in by physical principle
Thing surface is burnt, suffocate flame.Put out a fire in carbon dioxide extinguisher using the smothering action of inert gas and certain cooling effect,
Due to less residue after fire extinguishing, the initial of expensive equipment, archives material, instrument and meter, electrical equipment and oils is suitably applied
Fire.But these fire extinguishers have limitation, as dry powder extinguisher is only suitable for conventional A, B class fire, and cooling-down effect
Difference, environmental pollution is big, post processing is difficult;Fire foam can not be puted out a fire to save life and property mainly for B class fire, such as oil product, grease
Water miscible B classes fire, such as alcohol, ester, ketone, the fire of ether material, the C classes that can not put out a fire to save life and property and powered E classes fire;Carbon dioxide
Fire fighting with fire extinguisher ability is more general, and gas easily escapes under clearing, and asphyxia be present to human body at higher concentrations and endanger
Danger.Therefore, need to develop that extinguishing ability is stronger, the wider array of effective flame arrestor of fire attack type now.
Water mists are a kind of emerging high-effect fire-extinguishing technologies, and the technology is using fine mist spray head at elevated pressures by current
It is decomposed into diameter Dv99(Volume fraction is 99 % particle diameter)Droplet less than 1000 microns is put out a fire, and fire-fighting efficiency can reach
5-10 times of traditional Water spray technology.The fire-fighting principle of Water Mist Fire Extinguishing Technique includes flame cooling, oxygen barrier asphyxia, decay heat spoke
Penetrate, kinetics function.Water Mist Fire Extinguishing Technique has good extinguishing effect to A, B, C class fire, and it is water-soluble to put out a fire to save life and property
The B class fire of property.It is additionally, since water droplet diameter very little, mutually isolated and larger the air gap makes carefully between its droplet
The powered security performance of water smoke greatly promotes, and can be applied to the preventing and treating of powered E classes fire.
Patent 201020153410.7 discloses a kind of bladder-type portable water mist fire extinguisher, and the fire extinguisher includes fire extinguishing
Agent supply bag and fire gun, it sets extinguishing chemical capsule in pressure cylinder, by the air pressure of pressed gas that extinguishing agent pressure is defeated
Go out, and external pressure gauge and pressure-regulating valve regulation output pressure, realize the constant pressure output of water mists.But the structure design
Very high to the quality requirement of extinguishing chemical capsule, once there is trickle breakage, whole fire extinguisher will lose effect.Meanwhile the fire extinguisher
Assembling it is more complicated, dismounting is inconvenient, and structure is not compact.Moreover, the design can only realize single fine mist fire-fighting function, no
Extinction using gas function can be realized.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided one kind can realize fine mist fire-fighting
With the hand fire extinguisher of two kinds of functions of extinction using gas.Fire extinguisher can with the pressure injection water mists of continued for constant, water mists
Atomization quality is high and stably, and extinguishing ability is strong, and powered security performance is high.Meanwhile the fire extinguisher passes through simple adjustment, it is possible to achieve
Extinction using gas function.
In order to solve the above technical problems, technical scheme proposed by the present invention is:
A kind of portable constant pressure water mists-gas two sprays fire extinguisher, including the gas bomb equipped with gases at high pressure and equipped with going out
The liquid storage bottle of powder composition, the bottleneck of the liquid storage bottle connect a fine water fog spraying gun, the bottleneck of the gas bomb by pressure hose
Place, which is provided with, starts valve, and the exit for starting valve is provided with the pressure reducer and level pressure delivery valve being connected, and the level pressure is defeated
The outlet for going out valve is connected the gas bomb with the bottleneck of liquid storage bottle by a gas outlet duct, on the gas outlet duct
Provided with gas nozzle and gas-liquid conversion valve, by switching the gas-liquid conversion valve, the gases at high pressure in gas bomb pass through
After the pressure reducer and level pressure delivery valve are down to constant pressure, extinction using gas can be sprayed optionally through gas nozzle, or
Ejection fire extinguishing is atomized by the extinguishing medium in liquid storage bottle by the interior siphon pipe pressure output set and by fine water fog spraying gun constant pressure.
As the further improvement to above-mentioned technical proposal:
Preferably, the gas in the gas bomb is inert gas.
Preferably, the gas nozzle is divergence expression gas nozzle.
Preferably, the divergence expression gas nozzle is located on the gas-liquid conversion valve and drives cutting for gas-liquid conversion valve
Change, when adjusting divergence expression gas nozzle upward, gas-liquid conversion valve is dissengaged positions, realizes and sprays extinction using gas;Regulation diverging
Formula gas nozzle down when, gas-liquid conversion valve is connected state, realize spray fine mist fire-fighting.
Preferably, the startup valve is provided with pressure handle and pressure gauge, and the pressure handle is provided with lock.
Preferably, be provided with entrainment on the outside of the liquid storage bottle, the fine water fog spraying gun be located in the entrainment and liquid storage bottle it
Between.
Compared with prior art, the advantage of the invention is that:
Portable constant pressure water mists-gas two of the present invention sprays fire extinguisher, and utilizes interconnected gas bomb and liquid storage bottle
Double bottle structures, and by setting gas-liquid conversion valve on gas transmission pipeline, you can by the judgement to fire, pass through gas
The cut-out governing gas-liquid conversion valve, changed in two kinds of fire-fighting modes of water mists and gas;The bottleneck of gas bomb starts valve
Place is provided with pressure reducer and level pressure delivery valve, Z can be continuously maintained the constant pressure injection of water mists, and atomization ability is stable, and Quality of fogdrop is good,
Fire-fighting efficiency is high, and powered security is good and stably, and extinguishing medium less residue, the fire type that can be prevented and treated is comprehensive, can put out a fire to save life and property several
All fire types, water mists therein can put out a fire to save life and property conventional A, B, C and electric E classes fire, gas can be puted out a fire to save life and property
The initial fire of precision instrument, expensive equipment, and the fire that can be reacted with water that can not be puted out a fire to save life and property with water.With simple in construction,
The advantages that fire-fighting efficiency is high, and powered security is good and stably, and fire extinguishing type is comprehensive, it can be widely applied to civil buildings, electric
The fire-fighting domain of the important places such as equipment room, subway station, public building archives, computer room, library.
