Abstract
The utility model relates to a fire-extinguishing gun comprising a high pressure water inlet, high pressure water high pressure cavity chamber, a high pressure nozzle, a foam liquid inlet pipe, a subpressure chamber, etc. The utility model can extinguish fires with water and foam, and can be straightly sprayed or scattered.
Description
The utility model relates to a kind of Fire branch, international patent: A62C31/03.
At present extensively the direct-injection type Fire branch that adopts has two point defects: (1) can only water outlet, can not go out foam: when running into the oil gas fire, and bad control, the effect of therefore putting out a fire is bad, and the loss that causes is bigger; (2) can only direct projection, can not scattering: the area in the control scene of a fire be little during fire extinguishing, is unfavorable for fire extinguishing.
The purpose of this utility model be to provide a kind of can water outlet, can produce foam again; Can direct projection, Fire branch that again can scattering.
Technical solution of the present utility model is:
Water under high pressure water inlet 1 connects with fire hose by screw thread; Be provided with screen pack between water under high pressure high-pressure chamber 2 and the water under high pressure water inlet 1; Negative pressure chamber 5 lower ends are provided with foam solution inlet tube 4, are furnished with high pressure nozzle 3 between negative pressure chamber 5 and the water under high pressure high-pressure chamber 2; Be furnished with mixing nozzle 6 between secondary mixing tube 12 and the negative pressure chamber 5; Secondary mixing tube 12 is connected with duckbilled jet exit 11.
The beneficial effects of the utility model are:
1 this Fire branch can be realized the purpose of spray foam, can produce better effect for the oil of putting out a fire to save life and property, gas fire;
2 these Fire branch can be realized the function of scattering, more help strengthening control scene of a fire scope.
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the schematic diagram of a kind of foam gun of the utility model.
As shown in Figure 1, the utility model comprises water under high pressure water inlet 1, water under high pressure high-pressure chamber 2, high pressure nozzle 3, foam solution inlet tube 4, negative pressure chamber 5, mixing nozzle 6, helicla flute rotary handle 7, rotary handle annular groove alignment pin 8, helicla flute 9, helicla flute sliding tie rod 10, duckbilled jet exit 11, secondary mixing tube 12.
Water under high pressure water inlet 1 connects with fire hose; Be provided with screen pack between water under high pressure high-pressure chamber 2 and the water under high pressure water inlet 1; Negative pressure chamber 5 lower ends are provided with foam solution inlet tube 4, and are furnished with many group high pressure nozzles 3 between the water under high pressure high-pressure chamber 2; Be furnished with mixing nozzle 6 between secondary mixing tube 12 and the negative pressure chamber 5; It is on the circumference in the center of circle that high pressure nozzle 3 is arranged in the Fire branch centre bore, and with Fire branch centre bore symmetric arrangement; It is on the circumference in the center of circle that mixing nozzle 6 is arranged in the Fire branch centre bore, and with Fire branch centre bore symmetric arrangement.High pressure nozzle 3 is 2 pairs-6 pairs with the quantity of mixing nozzle 6.Secondary mixing tube 12 is arranged between mixing nozzle 6 and the duckbilled jet exit 11, and the length of secondary mixing tube 12 is 500-800cm.There is helicla flute rotary handle 7 in secondary mixing tube 12 outsides, and rotary handle annular groove alignment pin 8 can slide in helicla flute 9; Helicla flute sliding tie rod 10 1 ends are connected with rotary handle annular groove alignment pin 8, and the other end is connected with duckbilled jet exit 11.
Operation principle of the present utility model is described in detail in detail below:
One, the situation of only spraying water:
At this moment, foam solution inlet tube 4 closures, water under high pressure enters water under high pressure high-pressure chamber 2 by water under high pressure water inlet 1 and screen pack, enters negative pressure chamber 5 by high pressure nozzle 3 again; Enter secondary mixing tube 12 by mixing nozzle 6; At last by duckbilled jet exit 11 with high pressure water jets to fire-extinguishing location.
Two, the situation of injection water and foam mixing liquid:
Water under high pressure enters water under high pressure high-pressure chamber 2 by water under high pressure water inlet 1 and screen pack, enters negative pressure chamber 5 by high pressure nozzle 3 again; And in negative pressure chamber 5 and the foams mix that enters by foam solution inlet tube 4; The mixed liquor of water and foam enters secondary mixing tube 12 by mixing nozzle 6 to carry out secondary and mixes; By duckbilled jet exit 11 mixed liquor is sprayed onto fire-extinguishing location at last.
Three, the adjusting of direct projection and scattering:
No matter be the situation of only water spray or the situation of injection water and foam mixing liquid, the staff can carry out the adjusting of direct projection and scattering at the scene.Method is: by left rotation and right rotation adjustable screw groove rotary handle 7, affect helicla flute sliding tie rod 10 to move up and down.Because the front end of helicla flute sliding tie rod 10 is connected duckbilled jet exit 11, causes that duckbilled jet exit 11 opens, closure, but make the mixed liquor can direct projection scattering again.
