Abstract
The utility model relates to an air-foam fire extinguishing device, which comprises a high-pressure air bottle, a foam-water premixed liquid storage tank, a hose, a reel and an air-foam gun. The reel is mounted at the top of the foam-water premixed liquid storage tank, one end of the hose is connected to a liquid outlet of the foam-water premixed liquid storage tank while the other end is connected with the air foam gun, the hose is wound on the reel, a high-pressure inlet of the foam-water premixed liquid storage tank is connected with the high-pressure air bottle via a high-pressure air pipe, and the high-pressure air pipe is provided with a pressure reducing valve. Besides, a section variable joint pipe which is flared is in series connection between the hose and the air foam gun. A fire control station is replaced via the high-pressure air bottle and the foam-water premixed liquid storage tank, and a mixing mode of original foam entrainment via fire fighting water is replaced by premixed foam liquid which is more uniform in mixing, reliable in mixing ratio and fine in foaming effect. In addition, the air-foam fire extinguishing device is compact in structure, simple in process, low in maintenance and operation requirements and manufacturing cost and reliable in performance.
Description
Technical field
The utility model belongs to the fire fighting device technical field, is specifically related to a kind of novel aerofoam fire extinguishing installation.
Background technology
The air of Cai Yonging has different sizes such as 4L/s, 8L/s, 16L/s in the market, adopts the fire water inlet, and inlet diameter is generally D50 or D65.The side of foam gun connects a flexible pipe, and flexible pipe links to each other with the foam dope bucket again.Special construction by foam gun utilizes the injection of fire water to entrainment and enters foam dope, carries out the ratio of water, foam, air and mixes, from the outlet ejection.Such foam gun need connect fire water, promptly need start fire pump, complex procedures, and flow is big, very flexible.Be difficult to adapt to fire place in no fire water.Therefore need a kind of flexible, motor-driven novel air fixed froth installation, to adapt to the needs of special place fire extinguishing such as cities and towns, boats and ships.
The utility model content
At the problem that existing air exists, the utility model provides a kind of novel air fixed froth installation of simple in structure, convenient vehicle-mounted fast moving.
Concrete structural design scheme is as follows:
Aerofoam fire extinguishing installation comprises air 5 and flexible pipe 3; Also comprise foam-water premixed liquid storage tank 2, its top is provided with water inlet 7, safety valve 9 and pressurized gas inlet 13, and described foam-water premixed liquid storage tank 2 one sides are provided with the beneficial mouth of a river 8, and the bottom is provided with rushes down liquid mouth 15; Described pressurized gas inlet 13 is connecting gas cylinder 1 by high-pressure air pipe; Described gas cylinder 1 outlet is provided with pressure-reducing valve 6; Described foam-water premixed liquid storage tank 2 tops are provided with reel 4, and an end of flexible pipe 3 is connecting the liquid outlet 11 of foam-water premixed liquid storage tank 2, and the other end of flexible pipe 3 connects air 5 by the reduced section sub pipe, and flexible pipe 3 is coiled on the reel 4.
Described reduced section sub pipe 10 flares connect to form by two arc surfaces are smooth.
Described air foam dope suction inlet is provided with plug.
Useful technique effect of the present utility model is to replace the fire-fighting water station with gas cylinder and foams mix flow container.Apparatus structure compactness, technology are simple, attended operation require lower, and cheap, dependable performance.With the hybrid mode that the foam solution that is pre-mixed replaces fire water to flow and entrainment foam solution, to mix more evenly, mixing ratio is reliable, and foaming effect is good.Adopt two circular arc reduced section subs to connect flexible pipe and foam gun, to reduce caused backflow of variable cross-section and flow instability.
In addition, this device can be installed on the means of transport of go-cart and so on easily, is used for the initial stage of in time putting out fast or little medium-sized fire.The flexible pipe that is disposed can enlarge the scope of application of air.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, aerofoam fire extinguishing installation comprises foam-water premixed liquid storage tank 2,30 meters long flexible pipes 3, reel 4 and airs 5.Foam-water premixed liquid storage tank 2 tops are equipped with water inlet 7, safety valve 9 and pressurized gas inlet 13, and a side of foam-water premixed liquid storage tank 2 is installed the useful mouth of a river 8, and foam-water premixed liquid storage tank 2 bottoms are equipped with and rush down liquid mouth 15; Reel 4 is installed on foam-water premixed liquid storage tank 2 tops, and an end of flexible pipe 3 is connecting the liquid outlet 11 of foam-water premixed liquid storage tank 2, and the other end of flexible pipe 3 is connecting air 5, and ball valve 14 is installed on the flexible pipe 3, and flexible pipe 3 is coiled on the reel 4; The pressurized gas inlet 13 of foam-water premixed liquid storage tank 2 is connecting gas cylinder 1 by high-pressure air pipe, and gas cylinder 1 outlet is equipped with pressure-reducing valve 6.The reduced section sub pipe 10 of connecting between flexible pipe 3 and the air 5, reduced section sub pipe 10 flares tubaeformly connect to form by two arc surfaces are smooth; The original foam dope suction inlet 16 of air is provided with plug 17.
During the fire extinguishing operation, after the gas in the gas cylinder 1 reduces pressure through pressure-reducing valve 6, enter the air inlet 13 of foam-water premixed liquid storage tank 2 by high-pressure air pipe.Treat foam-when water premixed liquid storage tank 2 internal pressures reach operating pressure, open and open ball valve 12 and ball valve 14, foam mixing liquid in drive of high-pressure gas foam-water premixed liquid storage tank 2 ejects from air 5 through liquid outlet 11, flexible pipe 3 and reduced section sub pipe 10.The coefficient of foaming of air is 5～20.Foam mixing liquid concentration in the storage tank is 3%.
