Description
Technical field
The utility model belongs to the fire-fighting equipment technical field, is specifically related to a kind of compressed-air type A foam extinguishing device that fixedly mounts or be provided in the fire-fighting vehicle.
Background technology
In the past in the compressed-air type A foam extinguishing device with the rotating speed of water flow signal control class A foam liquid displacement pump, to realize water and class A foam liquid mixing to scale.Device adopts the balanced valve device that compressed-air actuated pressure is equated with the pressure of mixed liquor in addition, to realize that compressed air enters mixed liquor and forms two phase flow.Above-mentioned technology path not only makes the device feature complexity, involves great expense, and is difficult in maintenance, and the opereating specification of device is minimum, and the injection of compressed air class A foam is interrupted in the particularly easy drift of the equalization point of gas, hydraulic coupling.In a single day device forms the interruption of compressed air class A foam, fire extinguishing procedure can not be proceeded.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, technology simple, maintenance requirement is lower, stored-pressure type compressed-air type A foam extinguishing device with automatic mixed function.
A kind of compressed-air type A foam extinguishing device that the utility model proposes is made up of with air and liquid mixer 9, flow spoiler, air compressor 13 with air and liquid mixer 5, big gun water pump 1, electrically-controlled valve 2, foam proportioning unit 4, rifle, as shown in Figure 1.Wherein, water pump 1 links to each other with electrically-controlled valve 2, Pressure gauge 3, links to each other with foam proportioning unit 4 again, constitutes water supply feed flow pipeline; In the pipeline two tunnel links to each other with fire-fighting lance 8 with flow spoiler 6, hand-operated valve 7 with air and liquid mixer 5, rifle by rifle respectively; Third Road in the pipeline links to each other with fire water monitor 11 with flow spoiler 10, hand-operated valve 7 with air and liquid mixer 9, big gun by big gun; Air compressor 13 links to each other with gas tank 12, Pressure gauge 3, links to each other with hand-operated valve 7 again, constitutes air inlet pipeline; Air inlet pipeline links to each other with air and liquid mixer 9 with air and liquid mixer 5, big gun with two rifles respectively by electrically-controlled valve 2.
In the utility model, fire-fighting lance 8 has the heavy caliber nozzle.
In the utility model, foam proportioning unit 4 can mix in proportion, and it can adopt stored-pressure type, and mixing arrangement can be mixed water in two kinds of selectable regulation ratios in big range of flow with class A foam liquid.
In the utility model, big gun is used with air and liquid mixer and rifle and is formed the local depression district in the air and liquid mixer chamber, make the gas feed pressure of compressed-air actuated pressure greater than air and liquid mixer, thereby form mixed liquor local reduction, guaranteed that compressed air can stably enter in the air and liquid mixer to form biphase gas and liquid flow with mixed liquor.
In the utility model, adopt flow spoiler, biphase gas and liquid flow is flowed by sine wave, two phase flow can fully be stirred under the condition of the less pressure loss form uniform compressed air class A foam.
The course of work of the present utility model is as follows: the pressure water source that is provided by water pump 1 electrically-controlled valve 2 of flowing through is pressed into foam proportioning unit 4; mix the formation mixed liquor to scale with the class A foam liquid in the mixing arrangement 4; simultaneously big gun with or rifle with air and liquid mixer in the air that provides by air compressor 13 of adding; form mixed liquor-compressed air two phase flow; again through big gun with or rifle stir with flow spoiler; spray the compressed air class A foam by fire water monitor 11 or fire-fighting lance 8, to reach the superior fire extinguishing and the effect of thermal insulation protection.
Compressed-air type A foam extinguishing device of the present utility model need not flow signal acquisition the pressure balance of control and gas-liquid mixed control, apparatus cost is cheap, easy to operate, safeguard simple, can realize fire water monitor water spray reliably, spray mixed liquor, squirt foam and fire-fighting lance water spray, spray mixed liquor, squirt foam, all function such as spray dry foam, significantly improve the utilization rate of fire-fighting fire extinguishing ability and fire demand water.Compressed-air type A foam extinguishing device has the superior solid fire ability of putting out, improves fire-fighting lance, water cannon range ability, thermal insulation protection ability and the ability that conserves water, and has now become a cutting edge technology of modern fire-fighting.
