Abstract
The invention relates to the technical field of class A foam extinguishing installations, in particular to an air storage type compressed air class A foam extinguishing installation. A compressed air bottle is respectively connected with an air inlet end of a gas-liquid mixer, an air inlet end of a foam liquid tank and an air inlet end of a water tank; an outlet end of the foam liquid tank is connected with a foam liquid inlet end of a water-liquid mixer; a water outlet end of the water tank is connected with a water inlet end of the water-liquid mixer; an outlet end of the water-liquid mixer is connected with a liquid inlet end of the gas-liquid mixer; an outlet end of the gas-liquid mixer is connected with a hose which is connected with a foam gun; and a dry foam control valve and a wet foam control valve are connected in parallel on a pipeline between the foam liquid tank and the water-liquid mixer. Compared with the prior art, the compressed air supplied by the air storage bottle is used as water source power, water and foam liquid mixing power and the air required by foam generation, and the foam extinguishing installation has the advantages of reasonable structure, simple process, low maintenance operation requirements, low manufacturing cost, simple and convenient operation and reliable performance.
Description
[technical field]
The present invention relates to class A foam extinguishing device technical field, is a kind of gas storage type compressed-air type A foam extinguishing device specifically.
[technical background]
The compressed air class A foam went out meter apparatus system when producing foam in the past, required air is to be provided by air compressor, for pressure water source and the compressed-air actuated pressure flow that the water source is provided is complementary, this system except be water pump and air compressor machine the configuration power, also to dispose the pressure balancing system parts of water source and air, cause system complexity, involve great expense, operation and maintenance requirement be higher.
[summary of the invention]
The objective of the invention is in order to overcome the deficiencies in the prior art, replace air compressor with gas bomb, compressed air double as water source power, water and foam solution hybrid power that gas bomb provides and the required air of generation foam, and a kind of being installed on the delivery vehicles such as station wagon, battery truck and four-wheel motor of design put out the motor-driven high-effect fire-extinguishing device of middle-size and small-size fire.
For achieving the above object, a kind of gas storage type compressed-air type A foam extinguishing device is provided, it is characterized in that: the compressed air bottle port of export connects a pipeline, adopt branch again after establishing control valve on the pipeline, an inlet end that connects the solution-air blender, second inlet end that connects concentrated tank, the 3rd inlet end that connects water pot, the port of export of concentrated tank connects the foam solution entrance point of water liquid mixer, the water side of water pot connects the water inlet end of water liquid mixer, the port of export of water liquid mixer connects the liquid feeding end of solution-air blender, the port of export of solution-air blender connects flexible pipe, flexible pipe connects foam gun again, be arranged in parallel a dry foam control valve and wet foam control valve on the pipeline between described concentrated tank and the water liquid mixer, the perforate that described dry foam control valve is provided with is big, makes the foam solution that enters the water liquid mixer more relatively, expansion multiple 〉=15 of control dry foam, the volume ratio that contains foam solution is 8 ‰; The perforate that described wet foam control valve is provided with is little, and the foam solution that enters the water liquid mixer is less relatively, expansion multiple 〉=3 of control wet foam, and the volume ratio that contains foam solution is 3 ‰.
Also be provided with electric cabinet, establish battery in the electric cabinet, the power input of battery linker control element, the signal output part of sequence control element adopts circuit to connect the actuator of control valve, the actuator of dry foam control valve and the actuator of wet foam control valve respectively, described sequence control element such as PLC, encoder or relay, described actuator such as coil.
Described flexible pipe is around on the hose reel.
The present invention compared with prior art, replace air compressor with gas bomb, compressed air double as water source power, water and foam solution hybrid power that gas bomb provides and the required air of generation foam, apparatus structure is reasonable, technology is simple, the attended operation requirement is lower, and cheap, easy and simple to handle, dependable performance.

Referring to Fig. 1,1 is compressed air bottle; 2 is control valve; 3 is concentrated tank; 4 is the dry foam control valve; 5 is the wet foam control valve; 6 is the water liquid mixer; 7 is the solution-air blender; 8 is water pot; 9 is hose reel; 10 is flexible pipe; 11 is foam gun.
Appointment Fig. 1 is a Figure of abstract.
[specific embodiment]
Below the invention will be further described, the present invention is still more clearly for the people of this professional skill field.
When needs use, open the pressure-reducing valve on the compressed gas cylinder 1, make it to be in dormant state, open control valve 2 again and control supply solution-air blender 7, the pressure that water pot 8 and concentrated tank 3 are required, and control spray dry foam or wet foam, then control by switching dry foam control valve 4 or wet foam control valve 5, because in the dry foam control valve 4 with wet foam control valve 5 in the former the big latter of perforate of setting little, making the amount that enters the foam solution that mixes with water in the water liquid mixer 6 by switching dry foam control valve or wet foam control valve so also is that the former the big latter is little, water with enter solution-air blender 7 after foam solution mixes again and mix again from the gas in the compressed gas cylinder 1 after the extinguishing chemical that comes out be the dry foam shape or be the wet foam shape, the expansion multiple of dry foam 〉=15 wherein, contain foam solution and reach 8 ‰, the expansion multiple of wet foam 〉=3, contain foam solution and reach 3 ‰, the dry foam or the wet foam of fire extinguishing usefulness enter in the flexible pipe 10, eject by foam gun 11 again, described flexible pipe 10 is the time spent not, can be on hose reel 9.
The actuator of above-mentioned control valve 2, dry foam control valve 4 and wet foam control valve 5, the signal output part that connects the sequence control element in the electric cabinet as coil, the user can trigger control control corresponding valve by the corresponding button that is provided with on the electric cabinet, sequence control element such as PLC controller, the power supply of sequence control element is provided by the battery in the electric cabinet, and comes UNICOM's battery feed by set power knob.
