The utility model discloses a novel fire control foam gun, main pipe fitting including front and back assembled fitting in proper order, the rifle body and gun barrel, the internal hybrid chamber that is equipped with of rifle is equipped with the suction attachment that is linked together with the hybrid chamber on this rifle body, the internal correspondence of this rifle is equipped with the non return device with the position department that the suction attachment communicates. This novel fire control foam gun, the position department of the internal correspondence of rifle and suction attachment intercommunication has add the non return device, with the help of the non return function of this non return device, has prevented probably maloperation and leads to the water refluence to go into foam liquid bucket problem, has ensured herein that foam gun is normal, stable to use, still ensures good fire control effect simultaneously. Have, this is novel still to carry out the institutional advancement to rifle internal portion, herein promotes the effect that the negative pressure imbibition mixes and the atomizing foam produces, herein promotes foam gun's put out a fire stability and fire control effect again.

Description

A kind of Novel fire-fighting foam gun
Technical field
This utility model relates to fire-fighting equipment field, specifically refers to a kind of Novel fire-fighting foam gun.
Background technology
Foam gun is portable fire-fighting equipment, and available tube tooth interface connects with fire hose coupling, mixes and sucks air by fire-fighting pressure with foam solution, produce air foam, is used for putting out a fire to save life and property first, second, Class C liquid fire or injection water for general solid fire of putting out a fire to save life and property. Foam gun is general is connected use with foam hydrant, it is also possible to for foam fire truck. But, current foam gun is due to himself operation principle cause, in practical operation, it is easy to cause that because of maloperation aqueous reflux enters in foam solution bucket, there is the normal use of impact and extinguishing effect problem in this.
Utility model content
The purpose of this utility model is in that to provide a kind of Novel fire-fighting foam gun, succinct rational modification again in structure, it is therefore prevented that possible maloperation and cause that aqueous reflux enters foam solution bucket problem, it is ensured that foam gun normally uses and extinguishing effect.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of Novel fire-fighting foam gun, mainly includes the front and back tube tooth interface of assembly and connection, gun body and gun barrel successively; Being provided with hybrid chamber in gun body, this gun body is provided with the suction attachment being connected with hybrid chamber, and the position that the correspondence in this gun body connects with suction attachment is provided with check device.
The front end of described hybrid chamber offers water inlet, and the place rearward in this hybrid chamber is provided with nozzle, and this nozzle is provided with the nozzle entrance relative with water inlet, and the radial dimension of this water inlet is more than the radial dimension of nozzle entrance.
The junction of described suction attachment is provided with sealing ring.
Offering suction hole on described gun barrel, the axis of this suction hole is in from front to back toward tilted extended.
Described suction hole is provided with tandem two groups.
The free end of described gun barrel extends out thickening and is configured to reinforcement.
After adopting such scheme, this Novel fire-fighting foam gun, the position that correspondence in gun body connects with suction attachment has additional check device, check function by this check device, possible maloperation is prevented to cause that aqueous reflux enters foam solution bucket problem, ensure that foam solution bucket and foam gun use normal, stable in this, also assure that excellent extinguishing effect simultaneously.Also gun body inside is carried out structure improvement further, originally novel, in the effect that this lifting negative pressure imbibition mixing and atomized foam produce, in this fire extinguishing stability promoting foam gun and extinguishing effect.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of Novel fire-fighting foam gun, as it is shown in figure 1, mainly include the front and back tube tooth interface 1 of assembly and connection, gun body 2 and gun barrel 3 successively. Being provided with hybrid chamber 21 in gun body 2, the sidewall of this gun body 2 is provided with the suction attachment 4 being connected with hybrid chamber 21; Suction attachment 4 connects pipette 9.
The front end of described hybrid chamber 21 offers water inlet 211, and the place rearward in this hybrid chamber 21 is equiped with nozzle 6, and this nozzle 6 is to control flow and produce suction function. Gun body 2 is the bearing of foam gun, and tube tooth interface 1 is in order to be connected with water band. Being additionally provided with keying handle 7 and handwheel 8 in gun body 2, opening and closing handle 7 is foam gun cock and imbibition switch, and handwheel 8 is used for controlling foam gun and flows to, and gun barrel 3 is in order to regulate air foam liquid.
This novel main innovative point is in that, the position that the correspondence in gun body 2 connects with suction attachment 4 is provided with check device 5. This check device 5 can be check-valves or other non-return mechanisms. When press water is entered gun body 2 by water band through tube tooth interface 1, during by water inlet 211, the space (hybrid chamber 21) constituted between gun body 2 and nozzle 6 forms negative pressure. Hybrid chamber 21 is connected with pipette 9 by suction attachment 4, and pipette 9 other end inserts foam solution bucket and draws foam solution, makes foam solution mix in 6:94 ratio with water. When mixed liquor stream is by the nozzle entrance 61 of nozzle 6, spread atomization immediately, again form negative pressure and suck large quantity of air, mix with mixed liquor, produce air foam, produce good foam stream through the dynamic equilibrium in gun barrel 3 and eject. Check device 5 is installed on suction attachment 4 and hybrid chamber 21 junction, when there is maloperation or other fortuitous events, can prevent aqueous reflux from entering foam solution bucket, to guarantee that foam bucket, foam gun normally use, and the extinguishing effect of excellence.
Preferably, nozzle 6 is provided with the nozzle entrance 61 relative with water inlet 211. The radial dimension of this water inlet 211 is preferably greater than the radial dimension of nozzle entrance 61, is beneficial to negative pressure in this and is formed and atomizing effect.
Preferably, the junction of described suction attachment 4 is provided with sealing ring 41, and this sealing ring 41 can make pipette 9 vacuum seal, to guarantee negative-pressure liquid suction effect.
Preferably, gun barrel 3 offering suction hole, the axis of this suction hole is in from front to back toward tilted extended. This structural design is beneficial to suction hole and sucks large quantity of air, is finally beneficial to air foam and produces timely and effectively. Suction hole preferably can be provided with tandem two groups. Further, be also provided with pulverizer plate in gun barrel 3, this pulverizer plate is axially inclined to set relative to gun barrel 3, to strengthen mixed liquor diffusion atomizing effect, it addition, be also provided with foam screen in the rear of pulverizer plate, this foam screen is inclined to set equally, plays reinforcement air foam generation effect.
Preferably, the free end of gun barrel 3 extends out thickening and is configured to reinforcement 31. When being in an emergency, answering back to by gun barrel 3, reinforcement 31 plays reinforcement gun barrel 3 and answers back to intensity effect.
The foregoing is only this novel preferred embodiment, all equalizations done with this novel right change and modify, and all should belong to this novel scope of the claims.
