Abstract
The utility model discloses an automatic extinguisher with air pressure, which can make a new and highly efficient oil fire extinguisher realize automatic alarm and automatic fire extinguishing. The automatic extinguisher with air pressure is provided with the internal opening of a spraying nozzle on the side wall of the top of a stainless steel cylinder; the outer wall of the internal opening is provided with a piston box; the top cover part of the piston box is provided with an outer opening of a spraying nozzle; a steel bolt piston is arranged in the piston box; a center pipeline which is horizontally penetrated is arranged in the piston; the center pipeline is connected with the internal opening and the outer opening when the piston is pushed towards an upward direction. The lower part of the piston box is communicated with a combustion chamber. High pressure gas generated by combustion of a powder rod in arranged in the chamber, which makes the steel bolt piston be pushed towards an upward direction. Then fire extinguishing agents are sprayed to automatically extinguish fire. Meanwhile, the high pressure gas drives a pressure alarm to give out alarm through the upper hole of the combustion chamber.
Description
The utility model is with known new and effective oils fire extinguisher, realizes automatic warning self-extinguishing.
At present, use 1211(difluorochlobromo-methane) 1301(BTM 1202(difluorodibromomethane)) fire extinguisher of new and effective oils extinguishing chemical is that new and effective oils extinguishing chemical is equipped with shower nozzle with storage of higher pressures (because of so its boiling point hangs down with storage of higher pressures) steel cylinder top in stainless steel cylinder, one steel embolism is arranged in the shower nozzle, stop gases at high pressure to be overflowed, during fire extinguishing, need manually take out the steel embolism, shower nozzle be aimed at burning things which may cause a fire disaster put out a fire.
The prior art reference paper: read the middle school of cultivating people of ability, (senior middle school's fascicle) Shanghai City middle school student's encyclopaedic knowledge day and compile, the Intellectual Press publishes, in September, 1985 front page, the 236th " why rocket can fly? " the 341st " secret of 1211 extinguishing chemicals fire extinguishing "
The purpose of this utility model provides a kind of oils fire extinguisher that can report to the police automatically and can self-extinguishing.
The purpose of this utility model is achieved in that at the top of stainless steel cylinder establishes an air admission hole, is pressed into for new and effective oils extinguishing chemical.Establish a shower nozzle internal orifice at the sidewall at top, establish a piston case in the internal orifice outside, the top cover portion of piston case is established a shower nozzle collar extension, the built-in steel bolt of case piston, one intermediate conduit that laterally runs through is arranged in the piston, and when pushing away on the steel bolt piston, the piston intermediate conduit is connected inside and outside mouthful of shower nozzle.The bottom of piston case connects the combustion chamber and communicates the built-in gunpowder rod in combustion chamber with it.Establish a hole in addition on the sidewall of square steel tube on the lower side at the shower nozzle internal orifice, when pushing away on the steel bolt piston, this hole communicates with the combustion chamber.The top cover portion of combustion chamber has upper and lower two holes, and last hole and pressure alarm join, and outside, following hole is provided with desiccant chamber, in put drier, can prevent that humid air from entering the combustion chamber and stoping the gases at high pressure ejection.The desiccant chamber top cover portion has a hole, and blasting fuse is drawn through this hole by the combustion chamber.
Adopt such scheme, can make new and effective oils fire extinguisher realize warning, self-extinguishing automatically.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a profilograph of the present utility model.
In the accompanying drawing: 1. the outer oral pore 4 of oral pore 3 shower nozzles supplies blasting fuses to draw in 6 holes 7, through hole 5 confession setting pressure alarm holes with the combustion chamber when push away on the steel bolt piston mutually in 2 shower nozzles of 1 air admission hole hole, 7. desiccant chamber holes, stainless steel cylinder 2. piston case 3. steel bolt pistons, 4. intermediate conduit 5. steel bolt plunger handle, 6. combustion chambers
The embodiment explanation is put blasting fuse near the oily substance during use, and makes shower nozzle aim at the blasting fuse free-end.In the accompanying drawings, when burning things which may cause a fire disaster is lighted a fuse, drying agent chamber (7.) enters combustion chamber (6.) and causes gunpowder rod burning generation gases at high pressure, to push away on the steel bolt piston (3.), make steel bolt piston intermediate conduit (four) connect oral pore 2 and outer oral pore 3 in the shower nozzle, shower nozzle is unimpeded, and extinguishing chemical ejection is automatically put out a fire.
Simultaneously, stainless steel cylinder inner high voltage gas 4 imports the combustion chamber into through the hole, makes the high pressure conditions of holding the long period in the combustion chamber, and its pressure makes spreads to pressure alarm and report to the police and continue the long period on the steel bolt piston.
Claims (3)
1, the vapour-pressure type Automatic Fire Extinguisher is that known new and effective oils fire extinguisher is realized automatic warning self-extinguishing, it is characterized in that: oral pore 2 in the sidewall at stainless steel cylinder top is established a shower nozzle, 2 outsides, hole are established the top cover portion that the intermediate conduit that laterally runs through (a 4) piston case is arranged in a piston case (1) case built-in steel bolt piston (3) piston and are provided with the outer oral pore 3 of shower nozzle, the bottom of piston case connects combustion chamber (6) and communicates with it, and the hole 5 on the combustion chamber connects pressure alarm.
