For achieving the above object, the design of this explanation is:
Gas-foam spray extinguishing device is installed in the protected field, after fire takes place, the foam spray that fire extinguishing system is sprayed can utilize vaporescence to absorb a large amount of combustions heat, simultaneously can shroud flame, block radiation heat, therefore can control the intensity of a fire in the very first time on fire, effectively reduce fire scene temperature, avoid Hong combustion; Foam spray not only can reduce fire scene temperature, effectively controls the generation of flue gas, can not produce noxious material simultaneously, does not need complicated releasing process, can not damage personnel in the protection zone.For electrical fire in the protection zone; this gas-foam spray extinguishing device carries out extinction using gas; liquid gas rises to the nozzle place along gas piping; flash to gas rapidly; volume enlarges rapidly, absorbs a large amount of heats simultaneously, and the protected area temperature is sharply descended; and oxygen content in secluding air and the reduction air, and fire is extinguished.Effective control can guarantee safely to stamp out a fire gas-foam spray extinguishing device to the intensity of a fire in the separate space,
The utility model gas-foam spray extinguishing device, feature are that gas cylinder is fixed on the fluid reservoir limit, and the fire extinguishing pipe network is connected on the fluid reservoir, and fire extinguishing sprayer is connected on the pipe network.By each way switch solenoid control, switch electromagnetic valve is controlled by Fire extinguisher respectively in the keying of each shower nozzle.The keying of extinction using gas shower nozzle is by opening and closing solenoid control, and magnetic valve is controlled by Fire extinguisher.
When the breaking out of fire of certain, protected area, operating personnel start extinguishing device according to corresponding button on the conflagration area selection control panel, promptly start the bottle valve on the gas cylinder, and open the required switch electromagnetic valve of fire extinguishing.After starting magnetic valve and opening, gases at high pressure discharge through pressure-reducing valve from gas cylinder and drive extinguishing medium the fluid reservoir, the switch electromagnetic valve that extinguishing chemical is flowed through and opened under pressed gas drives, and the corresponding fire extinguishing sprayer of flowing through again carries out the foam spray fire extinguishing; When by the breaking out of fire of gas shield zone, operating personnel select the extinction using gas corresponding button, start the bottle valve on the gas cylinder, and open the keying magnetic valve on the gas piping, and gases at high pressure discharge from gas cylinder, put out a fire through the gas tip gas jet.
According to above-mentioned inventive concept, the present invention adopts following technical proposals:
A kind of gas-foam spray extinguishing device comprises a gas cylinder, fluid reservoir, pipe network, foam nozzle, gas tip and a controller, it is characterized in that:
1) described gas cylinder is placed in by the described fluid reservoir, the bottle valve of this gas cylinder is divided into two-way by air pipe behind a pressure-reducing valve, one the tunnel is communicated with the epicoele of this fluid reservoir, and another road is connected to described gas tip, and this gas tip is installed in to be needed in the gas shield zone;
2) described fluid reservoir top liquid outlet is connected described pipe network by the fluid pipeline through a hand control valve;
3) described pipe network be arranged on the protection zone inner roof wall vertical on, a plurality of foam nozzles are housed on the pipe network;
4) on the described foam nozzle switch electromagnetic valve is arranged, described bottle valve also is a kind of magnetic valve, and described controller connects described switch electromagnetic valve and bottle valve by lead.
5) a keying magnetic valve respectively is housed on the described gas tip, is connected in gas cylinder by pressure-reducing valve on the pipe network and bottle valve, described controller connects described keying magnetic valve and bottle valve by lead.
Above-mentioned foam nozzle has 2～12, and gas tip has 1～4.
Have on the control panel of above-mentioned controller and the identical press button of various shower nozzle quantity.Gas according to claim 1-foam spray extinguishing device is characterized in that having on the described control surface controller plate and the identical press button of various shower nozzle quantity; The circuit structure of controller is: the 220V AC power is connected the control magnetic valve of each shower nozzle respectively by the press button and the control relay of each parallel branch after a switch power module converts the 24V dc supply to.Simultaneously, the bottle valve on the gas cylinder connects the 24V dc supply by the control magnetic valve of each parallel branch.Described controller also has a stand-by power supply, by another control relay and 24V dc supply.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: the gas that the utility model provides-foam spray extinguishing device can carry out spray foam spraying fire extinguishing at breaking out of fire zone in the protection zone separately at specific area of fire protection; Simultaneously,,, arrange the extinction using gas shower nozzle, carry out extinction using gas as electrical control cabinet etc. in the zone that needs carry out gas shield.Its fire extinguishing less expensive, reasonable, effect is better.The utility model is simple in structure, and cost is low, is easy to apply.
