Description
Technical field
The utility model relates to a kind of automatic fire extinguisher, particularly relates to a kind of foam spray extinguishing device.
Background technology
The gas bomb of prior art foam spray extinguishing device is as power source, gas in it is in the storage of higher pressures state, and the control centre that gas bomb is controlled is generally only provided the startup power supply of DC24V, starting power is too little, be difficult to directly start the bottle valve of high-pressure gas cylinder, before starting high-pressure gas cylinder, must start little nitrogen cylinder (startup source) earlier like this, start high-pressure gas cylinder by the nitrogen in the little nitrogen cylinder again, this Starting mode makes high-pressure gas cylinder start complex structure, causes that package unit takes up room greatly, high, the poor stability of equipment cost.How to use small-power to start high-pressure gas cylinder, and can directly start power source, become the technical barrier that the industry is badly in need of solution without starting bottle.In addition, the safety valve no signal output function of conventional foam spraying extinguishing device is if pressure-reducing valve is breakdown, the supercharging rapidly of pressure-reducing valve outlet pressure can not be exported the superpressure signal when safety valve is opened, and nitrogen power source gas circuit can not be cut off rapidly, can cause fluid reservoir pressure to increase suddenly, cause danger; Traditional foam spray extinguishing device does not have microcomputer control and monitoring system, can not realize device is carried out Automatic Control, does not have functions such as real time on-line monitoring, Long-distance Control and browsing data.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of use reliable, foam spray extinguishing device little, that can realize on-line monitoring and Long-distance Control takes up room.
The utility model is achieved in that a kind of foam spray extinguishing device, comprise fluid reservoir, precompressed nitrogen power source, pressure-reducing valve, sectioning valve, waterfog head, fire alarm control unit and intelligent microcomputer, on this precompressed nitrogen power source the self-starting container value is set, the intelligence microcomputer links to each other with fire alarm control unit, opening of fire alarm control unit control precompressed nitrogen power source realized the on-line monitoring and the Long-distance Control of extinguishing device by intelligent microcomputer.
As further improvement of the utility model, signalization safety valve on this fluid reservoir, signalization export structure on the signals security valve can be realized the signal output function.
Further improve as of the present utility model, this self-starting container value is provided with the releasing pressure automatically hole, has charged automatic startup and meet an urgent need to manually boot two kinds of startup structures.
Operation principle of the present utility model is: self-starting container value, sectioning valve are in normally off under the preparation state, when the fire extinguishing condition is set up, fire signal is opened the self-starting container value by fire alarm control unit control, start the nitrogen power source, high pressure nitrogen enters fluid reservoir after reducing pressure by predetermined pressure by self-starting container value and pressure-reducing valve, to the extinguishing medium pressurization, open corresponding segmentation valve simultaneously, carry out sprinkling fire-distinguishing by shower nozzle.
Compared to existing technology, this device need not can directly start high-pressure gas cylinder through the startup source, and promptly the nitrogen power source is simple in structure, and it is little to take up room, and equipment cost is low; Adopt the signals security valve, improved the security and the reliability of package unit greatly; Adopt intelligent microcomputer that device is carried out Automatic Control and Long-distance Control, each key component duty of extinguishing device and transformer correlation behavior are carried out real time on-line monitoring, improved the level of IT application of system.
Description of drawings
Fig. 1 is a principle schematic of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1, fluid reservoir, 2, Pressure gauge, 3, the signals security valve, 4, the self-starting container value; 5, pressure-reducing valve, 6, fire alarm control unit, 7, sectioning valve, 8, the nitrogen power source; 9, waterfog head, 10, intelligent microcomputer, 11, signal cable, 12, protected object.
The specific embodiment
As shown in the figure, the utility model comprises fluid reservoir 1, Pressure gauge 2, signals security valve 3, self-starting container value 4, pressure-reducing valve 5, fire alarm control unit 6, sectioning valve 7, nitrogen power source 8, waterfog head 9, intelligent microcomputer 10 and signal cable 11.Signals security valve 3 band signal output functions, with self-starting container value 4 interlock protections in nitrogen power input gas circuit, output system superpressure signal carries out second protection to fluid reservoir 1 when breakdown fault takes place pressure-reducing valve 5.By signal cable 11, intelligence microcomputer 10 links to each other with fire alarm control unit 6, fire alarm control unit 6 links to each other with nitrogen power source 8 and sectioning valve 7, carry out Automatic Control and Long-distance Control by 10 pairs of whole extinguishing devices of intelligent microcomputer, each key component duty of extinguishing device and transformer correlation behavior are carried out real time on-line monitoring.The releasing pressure automatically hole is set on the self-starting container value 4, can prevent that the chronic leakage of gases at high pressure from causing the valve body error starting, during self-starting container value 4 normal startups, the releasing pressure automatically bore closure, the storage of higher pressures gas that prevents normal release is let out the hole discharge from this, thereby finishes the normal release of gas.Self-starting container value 4 is designed to charged automatic startup and meets an urgent need manually boot two kinds of Starting mode.
This device is self-starting container value 4 under the preparation state; sectioning valve 7 is in normal off status; when the fire extinguishing condition is set up; fire signal sends by fire alarm control unit 6; start power connection; for providing powered, the electromagnet on self-starting container value 4 valve bodies punctures guide's diaphragm in the valve; self-starting container value 4 is opened; nitrogen power source 8 starts; high pressure nitrogen enters fluid reservoir 1 after reducing pressure by predetermined pressure by self-starting container value 4 and pressure-reducing valve 5; pressurize to extinguishing medium; open corresponding sectioning valve 7 simultaneously, carry out sprinkling fire-distinguishing by 9 pairs of protected objects of waterfog head 12.
