Description
Technical field
The utility model relates to fire-fighting equipment technical field, specifically a kind of novel foam generator.
Background technique
Existing foam maker has played important function in fire brigade's fire fighting and rescue, but there is also it is following not
Foot: 1, existing mobile foam generator does not elevate the function of injection, is unable to satisfy the demand of disposition tank class fire;2, existing
The foam maker for having part to be connected on fire fighting truck water cannon need to change the structure of original water cannon region of interest, affect part function
Energy;3, in the market without the foam maker specially made for connection fire fighting truck water cannon, fire monitor only has lower curtate number foaming function
Energy.
Utility model content
The utility model aim is overcome the deficiencies in the prior art, realistic development is adapted to, according to the structure of fire fighting truck water cannon
It makes and makes a kind of novel foam generator, be connected on fire fighting truck water cannon, so that fire fighting truck is had the frothing function of middle high magnification numbe, fill
Divide and meets the needs of disposition tank class fire.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:
A kind of novel foam generator, including air inlet, foam cartridge, nozzle, nozzle interface and converting interface, on fire water monitor
Foam liquid pipe and the converting interface is coaxially fixed and the liquid outlet of the foam liquid pipe and the tail portion port of the foam cartridge
Alignment, the head port of the foam cartridge are foam outlet, are equipped with double-layer foamed web plate in the foam cartridge, on the foam cartridge
The air inlet is offered, the nozzle is fixed on the tail portion of the foam cartridge, and the nozzle and the nozzle interface are detachable
It is cooperatively connected, the nozzle interface and the converting interface pass through flange and bolt-connection.
Further, the intersection of the nozzle and the nozzle interface is equipped with deflector, offers and leads on the deflector
Flow chamber.
Further, the head of the nozzle to tail portion is in and is first gradually expanded and the pipeline configuration of after-contraction.
Further, the section of the foam bucket is ellipse.
Further, the foam cartridge is stainless steel quality.
The advantages of the utility model and good effect: air inlet is opened up on foam cartridge and increases coefficient of foaming, can be improved
The coefficient of foaming of 10%-15%;Nozzle head, in being first gradually expanded and the pipeline configuration of after-contraction, reduces flow velocity and increases to tail portion
The range of foam water 10%-15% can be improved in laminar flow;Deflector can be such that foam is more sufficiently mixed with water, facilitate foaming effect.
The utility model makes current elevating fire truck fire water monitor have the function of middle and high expansion of foam out, meets disposition
The demand of tank class fire;While not changing fire monitor original structure and not influencing its function, it is made to have middle and high multiple out
The function of foam;Coefficient of foaming can reach in times or more, the demand of fire brigade can be substantially met.
Detailed description of the invention
Fig. 1 is the utility model general structure schematic diagram;
Fig. 2 is foam cartridge cross section structure schematic diagram;
Fig. 3 is diversion cavity structural schematic diagram.
Specific embodiment
It is necessary to understand that, "upper", "lower", "top", "bottom", "inner", "outside" etc. refer in the description of the present invention,
The orientation or positional relationship shown is to be based on the orientation or positional relationship shown in the drawings, target only the utility model for ease of description
It is described with simplifying, is not that indication or suggestion institute finger must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it should not be understood as limiting the present invention.
It elaborates with reference to the accompanying drawing to specific embodiment of the utility model.
A kind of novel foam generator, as shown in Figs. 1-2, including air inlet 1, foam cartridge 2, nozzle 3,4 and of nozzle interface
Converting interface 5, the liquid outlet of the coaxial fixed and described foam liquid pipe of foam liquid pipe and the converting interface 5 on fire water monitor and institute
The tail portion port alignment of foam cartridge 2 is stated, the head port of the foam cartridge 2 is foam outlet, is equipped with foaming in the foam cartridge 2
Web plate offers the air inlet 1 on the foam cartridge 2, and the nozzle 3 is fixed on the tail portion of the foam cartridge 2, the nozzle
3 are detachably cooperatively connected with the nozzle interface 4, and the nozzle interface 4 passes through flange and bolt-connection with the converting interface 5.
The intersection of the nozzle 3 and the nozzle interface 4 is equipped with deflector 6, offers flow-disturbing on the deflector 6
Chamber;Head to the tail portion of the nozzle 3 is in first to be gradually expanded and the pipeline configuration of after-contraction;The section of the foam cartridge 2 is ellipse
It is round;The foam cartridge 2 is stainless steel quality.
When utility model works, foam mixing liquid enters foam maker from foam liquid pipe, after fire pump pressurizes,
Form at high speed injection enters foam maker import, forms (about 7 times) number bubbles of misty low power after being ejected into the deflector 6
Foam, according to the principle of Venturi, via the nozzle 3 by after its directly high speed injection to grid type foaming web plate, foam solution exists
Liquid film is formed on foaming web plate, compressed air advertises the liquid film on foaming web plate from the air inlet 1 into foam maker,
Times (about 40 times) several foams spray forward about 40 meters in formation, generate a large amount of foams and are discharged from the liquid outlet of foam liquid pipe.
Above-described embodiment is only the more excellent embodiment of the utility model, all according to the technical essence of the utility model pair
Any simple modification, modification and alternate variation made for any of the above embodiments, are all within the scope of the technical scheme of the utility model.
