Abstract
The invention discloses an air foam fire gun. The air foam fire gun is composed of an air foam mixing liquid nozzle, an air inlet, an extinguishant mixing liquid inlet, an extinguishant mixing liquid outlet, water spraying inclined nozzles, an annular liquid cavity, a water inlet and other structures, wherein the air foam mixing liquid nozzle is arranged at the front end; the air inlet is in the same axis with the mixing liquid nozzle and formed in the rear end; the extinguishant mixing liquid inlet and the extinguishant mixing liquid outlet are arranged in the axis center of the air inlet; the water spraying inclined nozzles are arranged on the combination portion of the mixing liquid nozzle and the air inlet and evenly and annularly arranged at intervals. According to the air foam fire gun, the wind power serves as the jetting power of a fire extinguishment system, and the air foam fire gun can be used in a forest fire extinguishment environment and various fire extinguishment environments as an air fire extinguishment device. A jetting system has a better structure, extinguishant foams and is jetted under the driving of power wind, and the jetting distance is large. The annularly arranged and inclined liquid outlets are adopted, higher negative pressure can be generated, more air is sucked in, and higher foaming expansion is generated. Liquid has no resistance when flowing, the device has no recoil force, the jetting distance is longer, foaming is adjustable in proportion and can even be closed, and the application range is wider.
Description
Technical field
The present invention relates to fire-fighting fire extinguishing utensil, particularly a kind ofly comprise the aerofoam fire extinguishing installation that air, fire foam and water are firing-fighting medium.
Background technology
In air, froth fire extinguishing system, the abundant Degree of Accord Relation of gas-liquid mixed is to the coefficient of foaming of fire foam, and coefficient of foaming is the important indicator of system fire extinguishing effectiveness, and the jet length of mixed liquor after foaming is the important performance indexes of system fire suppression applications ability.
Existing fire extinguishing system comprises fixed or portable fire extinguishing system, no matter fixed or portable fire extinguishing system is mainly spray power with liquor pump, its fire foam jet length formed is limited, and covering power is poor, is not suitable with the fire extinguishing needs in present multimode, the larger scene of a fire.
Fire gun is the major function equipment of fire extinguishing system, and existing fire gun comprises the functional structures such as water mists, each medium by spraying after fire gun mixing.But also do not have a kind ofly to realize multifunctional application and take wind-force as the high-power foam-making branch of power.
Summary of the invention
The present invention discloses a kind of air foam rifle according to the deficiencies in the prior art.The problem to be solved in the present invention is to provide one and water, fire foam, air three can be mixed by corresponding proportion, sprays the Recoilless fire gun of low multiple air foam agent.
The present invention is achieved through the following technical solutions:
Air foam rifle is cylindrical hollow configuration, it is characterized in that described fire gun comprises: the air foam mixed liquor spout being arranged at front end; With mixed liquor spout at same axis, the air intake arranging rear end; Be arranged at extinguishing chemical entry to mixed solution and the extinguishing chemical mixture export of air intake axis centre; Be arranged at mixed liquor spout and air intake joint portion, uniform intervals spray angle around the water arranged, water sprays angle axis and mixed liquor spout axis angle a is 17 ~ 30 degree; Water sprays angle and is communicated with the ring-shaped liquid chamber of mixed liquor spout with air intake joint portion outer wall, the water inlet that ring-shaped liquid chamber has outer watering to be communicated with; Extinguishing chemical entry to mixed solution and venturi-type eductors outlet, venturi-type eductors suction inlet passing ratio control valve is communicated with fire foam container, arranges bypass waterway be communicated with venturi-type eductors entrance at the water inlet in ring-shaped liquid chamber.
Described water sprays miter cut ring around layout 6.
Portable structure born by described fire foam container.
Described water inlet annularly fluid chamber tangential direction is arranged.
Described extinguishing chemical entry to mixed solution and bypass waterway be arranged in parallel, and bypass waterway is positioned at extinguishing chemical entry to mixed solution and fire gun tube wall connecting portion.
Above-mentioned venturi-type eductors is the suction type suction apparatus utilizing venturi principle to make, and has commercially available.
The present invention is a kind of bypass Venturi air foam-making branch.Comprise and can be placed in moveable backpack extinguishing chemical container, bypass venturi-type eductors, proportion adjustment valve, outer watering in backrest.Air intake and mixed liquor spout are arranged in same axial line, and air intake and mixed liquor spout joint portion are that water sprays angle, and the angle a that angle is formed is 17 ~ 30 degree, usually flow 2L/S during outer pressure of supply water 0.8mpa.Air foam rifle cavity casting ring-shaped liquid chamber, outer for the annularly fluid chamber tangential direction setting of fire extinguishing water inlet.Outer watering various ways, meets pressure 0.4mpa-1.2mpa and all can use, and namely fire hydrant, hand are lifted the pressure of supply water such as pump, fire fighting truck and can be run well.When outer watering supplies, current flow to venturi-type eductors by bypass waterway, form the extinguishing chemical that negative pressure passing ratio control valve draws certainty ratio, pass through stream shower nozzle again extinguishing chemical is sprayed to spray a place with outer watering angle and cross and clash into, form great negative pressure, suck large quantity of air from foam gun rear end, make water, fire foam, air three mixes by corresponding proportion, eject 7-20 air foam doubly.
The present invention take wind-force as the injection power of fire extinguishing system, and devise spraying system according to wind-force feature of spraying, the present invention is not when opening liquid and fire foam path, can be used as air extinguishing device and be applied to the environment such as forest extinguishing, after unlatching liquid and/or fire foam path, can be applicable to multiple fire extinguishing environment; Spraying system structure is more excellent, what spraying system achieved extinguishing chemical and water is thoroughly mixed to form foam, foam and spray further under the driving of power wind, jet length extends greatly, more be conducive to the application of the large scene of a fire, under scene of a fire traffic relative difficulty condition, the system that can give full play to is light, conveniently moving, closely realize the object of large power fire extinguishing.
Bypass Venturi air foam gun of the present invention, the skewed slot spout adopting liquid outlet to have constant slope sprays, and can produce the negative pressure larger than air foam nozzle, suck more air, produce higher coefficient of foaming, fluid flowing non-resistance, device Recoilless, jet length is farther, froth ratio is adjustable even closes, thus regulates foam humidity, and mixing arrangement structure is more succinct, easy to operate, reduce system equipment cost.
