Summary of the invention:
The technical problems to be solved in the utility model is that the oil fire of putting out a fire to save life and property does not have small-sized and adopts the fire fighting device of water as the extinguishing chemical carrier.For solving this technical problem, the utility model by the following technical solutions: air comprises liquid receiver 1, control valve 2, woven hose 3 and spray gun 4; Its special character is: spray gun 4 comprises rifle body 5, tube tooth interface 6 and jet pipe 7; The rear end of rifle body 5 is connected with tube tooth interface 6, and front end is connected with jet pipe 7; The middle part of rifle body 5 has hybrid chamber 8, and the front portion has air intlet 11; Hybrid chamber 8 has water inlet 9, foam solution import 10 and mixture export 12, and liquid receiver 1 is communicated with hybrid chamber 8 by control valve 2, woven hose 3 and foam solution import 10.
Liquid receiver 1 is used for the splendid attire fire foam, and it generally can make backpack.Whether the fire foam that control valve 2 is used for controlling liquid receiver 1 flows out.Woven hose 3 is used for making the fire foam of liquid receiver 1 to flow in the rifle body 5.Spray gun 4 is used for and will mixes by a certain percentage with water under high pressure from the water band from the fire foam of liquid receiver 1, forms air, and is ejected on the flame.Rifle body 5 is used for being connected with other parts, and fire foam and water under high pressure mix in the hybrid chamber 8 of rifle body 5 by a certain percentage.Air enters in the rifle body 5 from the air intlet 11 of rifle body 5, generates air with the mixture of fire foam and water.Tube tooth interface 6 is used for being connected with the water band, and the water under high pressure in the water band is entered in the rifle body 5, and it generally adopts the internal fastening type fire coupling to be connected with the water band.Jet pipe 7 is used for air is sprayed.
The front end of tube tooth interface 6 of the present utility model is connected by the rear end of screw thread with rifle body 5, and the junction is by sealing gasket 14 sealings; The aquaporin 15 of tube tooth interface 6 is coaxial with the aquaporin 16 of rifle body 5, and aquaporin 16 is communicated with hybrid chamber 8 by water inlet 9.
The front end of the hybrid chamber 8 of rifle body 5 of the present utility model has end cap 13, and end cap 13 is installed on the rifle body 5 by screw thread; By 20 sealings of O RunddichtringO, mixture export 12 is positioned on the end cap 13 between end cap 13 and the rifle body 5.
The outer surface of liquid receiver 1 of the present utility model has the cambered surface 23 that adapts with human body back, and braces 24 is installed.
Woven hose 3 of the present utility model is connected with the outer end of foam solution import 10 by fast interface 25.
The front portion of rifle body 5 of the present utility model is equipped with handwheel 21 by fastener.
Fastener generally adopts bolt clamp device.
In the tube tooth interface 6 of the present utility model sealing gasket 22 is installed.
The utility model can generate air with fire foam with after water mixes, and air can be directly used in and put out oil fire.Because the utility model liquid receiver 1 volume is less, can make backpack, is used with spray gun 4, makes the utility model become a kind of small-sized, light fire fighting device.Spray gun 4 of the present utility model can directly be connected with the water band, and water as the extinguishing chemical carrier, is particularly suitable for putting out the oil fire that takes place on the facilities waterborne such as boats and ships, oil tanker, overwater drilling platform.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of spray gun 4 among Fig. 1.
The specific embodiment:
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, present embodiment is a kind of backpack air, and it comprises liquid receiver 1, control valve 2, woven hose 3 and spray gun 4, and spray gun 4 is made up of rifle body 5, tube tooth interface 6, jet pipe 7 and handwheel 21.The rear end of rifle body 5 is connected by the front end of screw thread with tube tooth interface 6, and the junction is by sealing gasket 14 sealings.The front portion of rifle body 5 is connected with handwheel 21 by the rear end of bolt clamp device jet pipe 7.The middle part of rifle body 5 has hybrid chamber 8, and hybrid chamber 8 has water inlet 9, foam solution import 10 and mixture export 12.The front end of hybrid chamber 8 has end cap 13, and end cap 13 is installed on the rifle body 5 by screw thread.By 20 sealings of O RunddichtringO, mixture export 12 is positioned on the end cap 13 between end cap 13 and the rifle body 5.Water inlet 9 and mixture export 12 are coaxial, the axis normal of the axis of foam solution import 10 and water inlet 9.The aquaporin 15 of tube tooth interface 6 is coaxial with the aquaporin 16 of rifle body 5, and aquaporin 16 is communicated with hybrid chamber 8 by water inlet 9.Jet pipe 7 is divided into back segment 17, stage casing 18 and leading portion 19, and back segment 17 and leading portion 19 all are cylindrical, and stage casing 18 is conical.The diameter of back segment 17 is greater than the diameter of leading portion 19, is connected by stage casing 18 between back segment 17 and the leading portion 19.Back segment 17, stage casing 18 and leading portion 19 are coaxial, and coaxial with mixture export 12.Have control valve 2 on the liquid receiver 1, an end of woven hose 3 is connected with control valve 2.The other end of woven hose 3 is connected with the outer end of foam solution import 10 by fast interface 25.The outer surface of liquid receiver 1 has the cambered surface 23 that adapts with human body back, and braces 24 is installed.The front portion of rifle body 5 has 11, three air intlets 11 of three air intlets and evenly distributes on the taper seat of rifle body 5 front portions.Sealing gasket 22 is installed in the tube tooth interface 6.Be loaded with 3% mechanical foam extinguishing chemical in the liquid receiver 1.
