Summary of the invention
Main purpose of the present invention is to overcome the deficiency of above-mentioned technology, and a kind of automatic cabinet-type fire fighting device is provided.Improve fire-fighting efficiency and fire-fighting safety.
The present invention for achieving the above object, by the following technical solutions: a kind of automatic cabinet-type fire fighting device is characterized in that the helitank and the air accumulator that comprise automatic alarm controller, shower nozzle, cabinet and place cabinet; Be provided with the opening device by automatic alarm controller control on the described air accumulator, the port of export of described opening device is communicated with helitank by pipeline; Described helitank is connected with shower nozzle by the extinguishing chemical carrier pipe, is provided with the magnetic valve by automatic alarm controller control in the described extinguishing chemical carrier pipe.
Described opening device is made of magnetic valve, pressure cylinder and bottle-jack valve, and described magnetic valve is fixed on the pressure cylinder, and the outlet side of described pressure cylinder is connected with bottle-jack valve, and described bottle-jack valve is fixed on the air accumulator.
Described opening device is for starting magnetic valve.
Described pipeline is provided with the air duct pressure reducer.
Described helitank and air accumulator are at least one group.
The quantity of described shower nozzle is at least one.
Described helitank is provided with safety valve.
Beneficial effect: this device is by being connected with the automatic alarm controller of outside, receive outside temperature-sensitive, the signal that sends of sense smoke sensor stamps out a fire automatically, fire-fighting efficiency improves greatly, that 12 of carbon dioxide extinguisher installation is accompanied, 10 times of fire extinguisher of heptafluoropropane, be the 2-3 of condensed aerosol fire extinguishing device doubly; At connecting line the air duct pressure reducer is set, when air accumulator moment opens, reduces the pressure in the helitank, make it can explosion, the security that improves this device; Opening device adopts and directly opens bottle-jack valve by pressure cylinder, and on the one hand because pressure cylinder moment is large, it is convenient to open, and it is safe and reliable that machinery is opened bottle-jack valve on the other hand.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1, automatic alarm controller; 2, shower nozzle; 3, cabinet; 4, helitank; 5, air accumulator; 5-1, pipeline; 6, opening device; 6-1, magnetic valve; 6-2, pressure cylinder; 6-3, bottle-jack valve; 7, extinguishing chemical carrier pipe; 7-1, magnetic valve; 8, air duct pressure reducer; 9, safety valve.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of automatic cabinet-type fire fighting device, the helitank 4 and the air accumulator 5 that comprise automatic alarm controller 1, shower nozzle 2, cabinet 3 and place cabinet; Be provided with the opening device 6 by automatic alarm controller control on the described air accumulator 5, the port of export of described opening device 6 is communicated with helitank 4 by pipeline 5-1; Described helitank 4 is connected with shower nozzle 2 by extinguishing chemical carrier pipe 7, is provided with the magnetic valve 7-1 by automatic alarm controller control in the described extinguishing chemical carrier pipe 7.Above-mentioned automatic alarm controller is the N-6000 linkage type Fire Autoalarm that Honeywell fire-fighting safety-protection system (Shanghai) Co., Ltd. produces.
Described opening device is made of magnetic valve 6-1, pressure cylinder 6-2 and bottle-jack valve 6-3, described magnetic valve 6-1 is fixed on the pressure cylinder 6-2, the outlet side of described pressure cylinder is connected with bottle-jack valve, described bottle-jack valve 6-3 is fixed on the air accumulator, indirectly open bottle-jack valve by the solenoid control pressure cylinder, on the one hand because pressure cylinder moment is large, it is convenient to open, it is safe and reliable that machinery is opened bottle-jack valve on the other hand, avoids the aging short circuit of circuit and bottle-jack valve was lost efficacy.Described opening device also can start magnetic valve and be controlled by automatic alarm controller for starting magnetic valve, can directly open air accumulator.
In order to protect air accumulator and helitank to be provided with air duct pressure reducer 8 at pipeline, when opening, reduces air accumulator moment the pressure in the helitank, and make it can explosion, the security that improves this device.
This device is applicable to the multiple occasions such as warehouse, oil depot, boats and ships, machine room, change power distribution room, pump house, airport, station, office, archive office, library, workshop, put out a fire to save life and property A, B, C class fire and charging equipment fire, under the larger occasion of area, be at least one group in order to reach the fire extinguishing described helitank of effect and air accumulator, be connected in parallel.The quantity of described shower nozzle is at least one, and a plurality of shower nozzles can be installed in arbitrarily needed position.Described helitank is provided with safety valve 9, after pressure surpasses 1.4 MPas, discharge cut down that barrier is not for some reason opened, the pressure in the powder tank continues to rise, when the setting value that reaches safety valve (1.76 MPa), safety valve is opened, pressure release.
This device is by being connected with the automatic alarm controller of outside, receive outside temperature-sensitive, the signal that sends of sense smoke sensor stamps out a fire automatically, fire-fighting efficiency improves greatly, that 12 of carbon dioxide extinguisher installation is accompanied, 10 times of fire extinguisher of heptafluoropropane, be the 2-3 of condensed aerosol fire extinguishing device doubly.
Operation principle: when the temperature-sensitive in the automatic alarm controller or smoke detection during to the condition of a fire, send automatically controlled signal to automatic alarm controller, start thus magnetic valve, magnetic valve starting pressure cylinder, gas in the pressure cylinder injects in bottle-jack valve, open bottle-jack valve, so that the high pressure nitrogen in the air accumulator enters in the helitank that extinguishing chemical is housed by connecting line, pressurising in the helitank, when the pressure in the helitank reached certain pressure, automatic alarm controller sent signal, opens solenoid valve to the magnetic valve in the extinguishing chemical transfer pot, thereby extinguishing chemical is sprayed from shower nozzle under the promotion of nitrogen, put out a fire.Magnetic valve described here also can be pressure relief valve, automatically detects the pressure in the helitank, can automatically open when the pressure in the tank reaches 1.4 MPa.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
