Abstract

The utility model relates to a new type of cart-styled pulse spray gun, belonging to the technical field of fire equipment, which comprises of an ejector1, a storage bucket 9 arranged in the cart, a high pressure storage cylinders 8, a low pressure gas pipeline 6, a water pipeline 4, another high pressure storage cylinders 10 tied on the backplane and a middle pressure gas pipeline 7. The gas pipeline 7 can be greatly shortened, and the water pipeline 4 ranges from 20 to 50 meters, whereas the firefighters can have a wide scope of activities, operate easily and select the best fire-fighting position and angle to wet down fires with high efficiency and good effect.

Description

Novel cart type pulse nebulization technique rifle

Technical field:

The utility model is a kind of novel cart type pulse nebulization technique rifle, for a kind of fire extinguishing equipment, belongs to the fire-fighting equipment technical field.

Background technology:

Now Chang Yong pulse nebulization technique rifle as shown in Figure 1, it is made up of injector 1, high pressure gas cylinder 8, water butt 9, two-way pressure reducer 5, middle pressure appendix 7, low pressure appendix 6 and water-supply-pipe 4, water butt 9 is connected with the water storage room 11 of injector through water-supply-pipe 4, high pressure gas cylinder 8 is by behind the two-way pressure reducer 5, press appendix 7 to be connected in one route with injector gas dome 12, another route low pressure appendix 6 is connected with water butt 9, and water butt 9 is arranged in the go-cart with high pressure gas cylinder 8.The gas dome 12 and the water storage room 11 of injector 1 drive quck-opening valve 3 by pulling of trigger 2, both are communicated with or obstructed and make it be pulse nebulization technique, (the being generally 2.5MPa) high speed of calming the anger in when being communicated with in the gas dome 12 is dashed to water storage room 11, and mix with water in the water storage room 11 and roll and form air-water mixture and dash to the injector exit, split by turning over of rice word rubber baffle and to make it be high speed atomized flow ejection, can put out the combustion fire fast.This fire extinguishing equipment because of the extinguishing chemical wide material sources, be easy to obtain, inexpensive, the fire extinguishing non-secondary pollution, good extinguishing effect, and all can use oils fire, gas fire and electrical fire is so be widely adopted.But be to be with water-supply-pipe 4 when the fire extinguishing also by the fire fighter because of the middle pressure appendix 7 in itself structure, its length is generally 5～10 meters, therefore directly influenced the ability of fire fighter near the scene of a fire, and middle pressure appendix 7 is carried with the dual circuit of water-supply-pipe 4, very easy generation pipeline winding when fire fighting, and influence fire extinguishing effectiveness, as with this two-tube employing coaxitron, pipe gas transmission promptly, the outer tube water delivery then again can the cost height, and weight is big, cause that fire fighter's labour intensity is big, the action flexibility greatly reduces therefore anxious must the improvement during fire extinguishing.

Summary of the invention:

The purpose of this utility model is to improve existing structure, and is long so that a kind of fire-fighting efficiency height, spray gun displacement to be provided, the novel cart type pulse nebulization technique rifle that the motor-driven agile property of fire fighter is good, load capacity can alleviate.

The purpose of this utility model is to realize like this, a kind of novel cart type pulse nebulization technique rifle includes injector 1, high pressure gas cylinder 8, water butt 9, low pressure appendix 6, the middle appendix 7 of pressing, water-supply-pipe 4, injector 1 is provided with gas dome 12, water storage room 11 and trigger 2 and quck-opening valve 3, water-supply-pipe 4 is connected the delivery port of water butt 9 with the water storage room 11 of injector, water butt 9 is arranged in the go-cart, it is characterized in that being provided with a high pressure gas cylinder 8 in a side of water butt 9, outlet at high pressure gas cylinder 8 is provided with a single channel pressure reducer 51, and the air inlet of pressure reducer 51 with water butt 9 is connected by low pressure appendix 6, other has a high pressure gas cylinder 10 to tie up on backboard, and by pressing appendix 7 to be connected with the gas dome 12 of injector 1 in single channel pressure reducer set on it 52 warps, the length of water-supply-pipe 4 can reach 20～50 meters.

Advantage of the present utility model is: the pipeline of water-supply-pipe can extend greatly, and it can be expanded to 20～50 meters by original 5～10 meters, can make the fire fighter be easy to select best fire extinguishing position, fire extinguishing angle, so the fire-fighting efficiency height, maneuverability is good.And the improvement of this structure, press appendix 7 can foreshorten to 1.1 meters in not only making, and significantly reduce the weight of appendix, and make and press that the pipeline winding problem in the double tube conveying is solved completely between appendix 7 and the water-supply-pipe 4 in original, maneuverability when making the fire fighter movable is good, and labour intensity is improved, and operates more convenient, but also one man operation's fire extinguishing, fire-fighting efficiency is high and structure equipment is also more reasonable.

Fig. 1 is the structural representation of existing pulse nebulization technique rifle

Fig. 2 is the structural representation of the utility model embodiment 1

The specific embodiment:

Fig. 2 is embodiment 1 of the present utility model, the novel cart type pulse nebulization technique rifle of present embodiment as seen from Figure 2, its structure is as above described in the surface technology scheme, wherein water butt 9 capacity can be 35L, high

pressure gas cylinder

8,10 capacity are 4.3L, unidirectional pressure reducer 52 is to press pressure reducer in one, it is input as 30MPa, be output as 2.5～2.7MPa, single channel pressure reducer 51 be a low pressure reducing valve its be input as 30MPa, be output as 1.1～1.37MPa, because of high pressure gas cylinder 10 is tied up on backboard, the fire fighter carries on the back it on back, carry on the shoulder that the pulse nebulization technique rifle just can drag water-supply-pipe 4 (length of water-supply-pipe is 20～50 meters in the present embodiment) easily and as much as possible near fiery kitchen range, select favorable terrain, and can realize fire extinguishing from different orientation to fiery kitchen range emission firing-fighting medium easily, thereby improve fire-fighting efficiency and fire extinguishing effect greatly and alleviate fire fighter's labour intensity.
