Description

The indoor fire-retardant fire-fighting system of gas escape type

Technical field

The utility model belongs to the improvement of fire-fighting equipment structure, particularly the fire-retardant fire-fighting system of indoor gas escape type.

Background technology

Conventional showering fire extinguishing system can be because of insufficient water, too high building, pump head or pipe network water pressure, High Temperature Gas Resistance, spray angle, generation of pernicious gas etc. hinder the objective factor of water spray effectively fire extinguishing to lose optimal fire extinguishing opportunity, so that rescue The personnel of helping abandon fire rescue plan.Additionally, existing various hand-held fire extinguishers are also restricted by place objective environment of catching fire Initial dying fire source or open flame source can only be put out, it is impossible to put the large-scale combustion flame for spreading and coming out by water.Therefore, existing showering fire extinguishing Equipment or hand-held fire extinguisher fire extinguishing work efficiency and fire extinguishing rate it is relatively low, use cost is higher.

Utility model content

The purpose of this utility model is to provide a kind of indoor fire-retardant fire-fighting system of gas escape type, and fire extinguishing work efficiency and fire extinguishing rate are more Height, use cost is lower.

What the purpose of this utility model was realized in：A kind of fire-retardant fire-fighting system of indoor gas escape type, source nitrogen enter air nozzle, First snap joint, the normally closed filling valve of nitrogen, nitrogen storing tank, pipe connects the first normally opened main control valve successively in a series arrangement, in nitrogen With first pressure table and the first safety valve is filled with gas storage tank, the first normally closed solenoid valve is with the first normally closed hand-operated valve with side in parallel Formula mutually pipe connects, and the first normally opened main control valve passes sequentially through first normally closed solenoid valve and the first normally closed hand-operated valve of parallel connection, the first list Gaseous mixture storage tank is connect to valve pipe, carbon dioxide air source enters air nozzle, the second snap joint, the normally closed filling valve of carbon dioxide gas, two Carbonoxide gas storage tank, pipe connects the second normally opened main control valve successively in a series arrangement, with being filled with the on carbon dioxide gas storage tank Two pressure gauges and the second safety valve, the second normally closed solenoid valve are connect with the second normally closed hand-operated valve with parallel way mutually pipe, and second is normal Open main control valve and pass sequentially through the second normally closed solenoid valve and the second normally closed hand-operated valve, second one-way valve tube of parallel connection and connect gaseous mixture and store Tank, with the 3rd pressure gauge is filled with gaseous mixture storage tank, normally closed electromagnetism air outlet valve and normally closed manual air outlet valve are with parallel way Mutual pipe is connect, and gaseous mixture storage tank is connect and disappeared by some to normally closed electromagnetism air outlet valve and normally closed manual air outlet valve pipe parallel with one another Sound air nozzle, normally closed electromagnetism air outlet valve, normally closed manual air outlet valve and noise reduction air nozzle are installed indoors, and pyrotechnics is installed with indoors Induction controller and electronic acousto-optic alarm, pyrotechnics induction controller are electrically connected normally closed electromagnetism air outlet valve and electronic acoustooptic report Alert device.

The utility model is obtained by vehicle-mounted liquid nitrogen source or vehicle-mounted liquid carbon dioxide source is used as nontoxic, free from corrosion resistance The compressed nitrogen or compression carbon dioxide gas of agent are fired, i.e.,：When vehicle-mounted liquid nitrogen source or vehicle-mounted liquid carbon dioxide source pass through pipeline Connect during into air nozzle, the nitrogen or carbon dioxide gas after decompression just can pass sequentially through snap joint, normally closed filling valve, the nitrogen opened Gas/carbon dioxide gas storage tank, normally opened main control valve, the normally closed solenoid valve/normally closed hand-operated valve opened, check valve are irreversibly filled To gaseous mixture storage tank, unnecessary nitrogen or carbon dioxide gas are then laid in nitrogen/carbon dioxide gas again in filling process In storage tank.When pyrotechnics induction controller then opens normally closed immediately when sensing that indoor appearance discharges the dying fire or naked light of smog Electromagnetism air outlet valve simultaneously makes electronic acousto-optic alarm send sound and light alarm, reminds and is withdrawn rapidly to outdoor security ground positioned at indoor occupant Band, at the same time, the nitrogen and/or carbon dioxide gas being previously stored in gaseous mixture storage tank will be through normally closed electromagnetism outlets Valve/normally closed manual air outlet valve, noise reduction air nozzle is discharged to interior carries out efficient fire-fighting operation, with prevent indoor dying fire or naked light after Continuous spreading then make its final extinguishing.If dying fire or naked light are attached to when on indoor aluminum object, only nitrogen can Aluminum object is prevented to participate in burning.Pressure gauge is used to monitor gaseous mixture storage tank, nitrogen/respective gas of carbon dioxide gas storage tank Pressure, safety valve is used to discharge nitrogen/unnecessary gas of carbon dioxide gas storage tank in order to avoid pressure inside the tank is too high, normally closed hand-operated valve and Normally closed manual air outlet valve can be by manual-operated emergent in the case where normally closed solenoid valve and normally closed electromagnetism air outlet valve hinder closure pipeline for some reason Enable to ensure nitrogen or carbon dioxide gas release that everything goes well with your work carries out.

In sum, the utility model fire extinguishing work efficiency and fire extinguishing rate are higher, and use cost is lower.
