Abstract

The utility model discloses a high pressure water mist foam extinguish pistol, which comprises a pistol body, a spray nozzle, a liquid pipeline and a high pressure liquid source, wherein, a foam pipeline and a water mist pipeline are arranged inside the pistol body; a switch valve is arranged between the foam pipeline, the water mist pipeline and the liquid pipeline, and in contact with a pistol switch; the other ends of the foam pipeline and the water mist pipeline extend out of the pistol body and are communicated with the spray nozzle; a foam spray nozzle is arranged on the foam pipeline of the spray nozzle, and a water mist spray nozzle is arranged on the water mist pipeline of the spray nozzle; and a plurality of air suction holes are formed on the outer wall of the spray nozzle close to the pistol body and is communicated with the foam pipeline inside the spray nozzle. The high pressure water mist foam extinguish pistol has the advantages of simple structure, light weight, low cost, safety and reliability, convenient use and low probability of damage, and can efficiently extinguish various fire hazards.

Description

The high pressure water mist foam extinguishing rifle

Technical field

The utility model relates to a kind of fire plant, is specially a kind of high pressure water mist foam extinguishing rifle.

Background technology

At present, in fire-fighting fire extinguishing, a kind of fire extinguisher is only effective at certain particular types fire.The fire fighter does not understand the situation in the scene of a fire when setting out the scene of fire, does not know the type of fire, therefore, need carry the extinguishing device of all kinds fire.After arriving the scene of fire, need select corresponding extinguishing device for use according to the type of fire.Above-mentioned situation makes that fire fighter's equipment weight is big, uses inconvenience, incurs loss through delay the best opportunity of fire extinguishing sometimes, and the loss that fire is caused strengthens.Chinese patent, notification number CN 2875506Y disclose a kind of multi-functional water smoke fire extinguishing spray gun, though its rifle body weight is light, can effectively put out the polytype fire, but its complex structure, cost is higher, fragile during use, thus incur loss through delay the best opportunity of fire extinguishing, and the loss that fire is caused strengthens.

Summary of the invention

The utility model is in order to overcome weak point of the prior art, to provide a kind of rifle body weight light, and volume is little, and is easy to use, can effectively put out the polytype fire, non-damageable high pressure water mist foam extinguishing rifle.

The technical scheme that its technical problem that solves the utility model adopts is as follows:

The high pressure water mist foam extinguishing rifle comprises rifle body, shower nozzle, fluid pipeline, high pressure liquid source, is provided with foam pipeline, water smoke pipeline in the described rifle body; Be provided with switch valve between described foam pipeline, water smoke pipeline and the fluid pipeline, described switch valve contacts with the rifle switch; It is external and be connected with shower nozzle that the other end of described foam pipeline, water smoke pipeline stretches out rifle; The foam pipeline of described shower nozzle is provided with foam jet, and the water smoke pipeline of described shower nozzle is provided with hydraulic spray nozzle; The outer wall that described shower nozzle is close with the rifle body is provided with several air entries, and described air entry communicates with the foam pipeline in shower nozzle.

Described hydraulic spray nozzle is several and is interconnected.

Described hydraulic spray nozzle is 6 and is interconnected.

Described air entry is 5.

Described switch valve is the 2/2-way valve.

The utility model high pressure water mist foam extinguishing rifle possesses spray foam, two kinds of functions of water smoke, when switch valve is connected fluid pipeline with the foam pipeline, and the utility model high pressure water mist foam extinguishing rifle spray foam; When switch valve is connected fluid pipeline with the water smoke pipeline, the utility model high pressure water mist foam extinguishing rifle water spray.The utility model tool high pressure water mist foam extinguishing rifle since simple in structure, in light weight can be a large amount of be equipped among the fire fighter, also can large-scale popularization use at medium and small chemical enterprise.

The utility model has the advantages that: simple in structure, in light weight, with low cost, safe and reliable, easy to use, not fragile, can effectively put out the polytype fire.

Label declaration among the figure: 1-rifle body; The 2-shower nozzle; The 3-fluid pipeline; 4-foam pipeline; 5-water smoke pipeline; The 6-switch valve; The 7-air entry; The 8-negative pressuren zone; The 9-foam jet; The 10-hydraulic spray nozzle; 11-rifle switch; 12-high pressure liquid source.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

A kind of high pressure water mist foam extinguishing rifle comprises rifle body 1, shower nozzle 2, fluid pipeline 3, high pressure liquid source 12, is provided with foam pipeline 4, water smoke pipeline 5 in the described rifle body 1; Be provided with switch valve 6 between described foam pipeline 4, water smoke pipeline 5 and the fluid pipeline 3, described switch valve 6 contacts with rifle switch 11; The other end of described foam pipeline 4, water smoke pipeline 5 stretches out outside the rifle body 1 and with shower nozzle 2 and is connected; The foam pipeline 4 of described shower nozzle 2 is provided with foam jet 9, and the water smoke pipeline 5 of described shower nozzle 2 is provided with hydraulic spray nozzle 10; Described shower nozzle 2 and rifle body 1 close outer wall is provided with 5 air entries 7, described air entry 7 shower nozzle 2 in foam pipeline 4 places of communicating formation negative pressuren zone 8; Described hydraulic spray nozzle 10 is 6 and is interconnected; Described switch valve 6 is the 2/2-way valve.

Its course of work: when switch valve 6 was connected fluid pipeline 3 with foam pipeline 4, because air entry 7 forms negative pressuren zone 8 with foam pipeline 4 places of communicating in shower nozzle 2, highly pressurised liquid formed foam herein, and by foam jet 9 ejections; When switch valve 6 was connected fluid pipeline 3 with water smoke pipeline 5, highly pressurised liquid formed water smoke and ejection by hydraulic spray nozzle 10.By rifle switch 11 gauge tap valve 6 flexibly, the polytype fire can be effectively put out in the selection of spraying foam or water smoke very easily according to scene of a fire needs.

Certainly, under inventive concept of the present utility model, the utility model has multiple form of implementation, and this reads and need not pay creative work behind this specification and can reproduce, all within protection domain of the present utility model to those skilled in the art.
