Abstract
The utility model discloses a quantity-variable foam mixing device. The quantity-variable foam mixing device comprises a valve, wherein the upper part of the valve is provided with a pipette; one end of the lower part is provided with a water hose connecting pipe, and the other end of lower part is provided with a spray gun connecting pipe; a foam mixing valve is arranged between the water hose connecting pipe and the spray gun connecting pipe; and a foam adjusting valve is installed from the top part of the valve to control the open and closure of the pipette. The quantity-variable foam mixing device disclosed by the utility model has the benefits that the cost of manufacture is low, the user is convenient, and the fire-fighting efficiency is high.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment improvement technology, particularly a kind of variable foams mix device.
Background technology
In recent years, because the excellent properties of foam annihilator makes fixed froth installation use more and more widely, the multifunctional foam mixed atomizing device of China has also all been obtained remarkable achievement in research, exploitation and application.This foam type extinguishing device can put out a fire to save life and property various hydrocarbon and polarity fuel fires, and category-A fire material had depth of penetration and moistening cooling effect.Foam blanket has good anti-resume combustion effect, and fire extinguishing only needs very thin one deck foam.
This installs the shortcoming that exists at present: device is formed complicated, can only use a kind of foaming agent of concentration, can not regulate according to the foaming agent of purchase, uses to have limitation.
Summary of the invention
The purpose of the utility model is in order to address the above problem, to have designed a kind of variable foams mix device.
The technical scheme that realizes above-mentioned purpose the utility model is that a kind of variable foams mix device comprises valve body; Valve body top is provided with pipette; Bottom one end has water band tube connector, and the other end has spray gun and takes over, and water band tube connector and spray gun are the foams mix valve between taking over; The foam control valve has the valve body top to pack into, the switch of control pipette.
Said foam control valve is to have three inlet openings and outlet to be positioned at the changeover valve of bottom.
In the said foams mix valve foam mixing chamber is arranged.
Utilize the variable foams mix device of the technical scheme making of the utility model, its operation is easy more rapidly, reliability is stronger.When the fire early period of origination, motor-driven, promote this device neatly and put out a fire to fire-extinguishing location.This device can also can cooperate large-scale fixed froth fire extinguishing system to play auxiliary salvage independently as fire-fighting defence equipment.Low price, manipulate and easy to maintenance, injecting time is long, extinguishing property is high.Unique foam adjustable function can allow the foaming agent of different proportionings to use according to the intensity of a fire simultaneously or selectively, has increased the flexibility of fire-fighting, helps the fire fighter better to use.
Description of drawings
Fig. 1 is the structural representation of the said variable foams mix of the utility model device;
Fig. 2 is the structural representation of the described foam control valve of the utility model;
Among the figure, 1, water band tube connector; 2, foams mix valve; 3, pipette; 4, foam control valve; 5, spray gun is taken over; 6, foam mixing chamber.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being specifically described, is the structural representation of the said variable foams mix of the utility model device like Fig. 1, and Fig. 2 is the anatomical structure figure of this variable foams mix device; As shown in the figure, a kind of variable foams mix device comprises valve body; Valve body top is provided with pipette 3; Bottom one end has water band tube connector 1, and the other end has spray gun and takes over 5, and water band tube connector and spray gun are foams mix valve 2 between taking over; Foam control valve 4 has the valve body top to pack into, the switch of control pipette.Wherein, said foam control valve is to have three inlet openings and outlet to be positioned at the changeover valve of bottom; In the said foams mix valve foam mixing chamber 6 is arranged.
The water band tube connector of its variable foam mixer is connected with fire hose when fire extinguishing; And connection pressure water source; Cross in the foams mix valve with very high velocity flow as the water that is not less than the 3.5Mpa operating pressure; Because the diffusion that laterally moves of jet particle, the indoor formation vacuum of the foams mix of foams mix valve (negative pressure) is so the foam solution in the foam fluid reservoir gets into the foams mix valve through pipette under the pressure effect of atmosphere; Mix with press water, finally reach a certain proportion of mixed liquor.When the mixed liquor stream with certain pressure is taken over spray gun through spray gun, because the performance of spray gun can suck air in certain amount, make the foam mixing liquid foaming, thereby reach the effect of foam fire-fighting.Wherein, The outer surface of foam control valve has three inlet openings and is communicated with the outlet of bottom; Make different inlet openings dock through rotation foam control valve with pipette; Thereby make exist in the market 3 in the foaming agent of different proportionings all can in this device, use, avoided selecting the unicity of foaming agent, can let the fire fighter select different fire foams according to the situation of the intensity of a fire.。
Technique scheme has only embodied the optimal technical scheme of the utility model technical scheme; The technical staff in present technique field to some part wherein some changes that possibly make all embodied the principle of the utility model, belong within the protection domain of the utility model.
