Description
Technical field
The utility model relates to fire-fighting equipment technical field, is specifically related to a kind of foam proportioning unit.
Background technology
Foam annihilator mainly by spraying great amount of carbon dioxide and foam, making it stick on combustible, making combustible and air exclusion, destroys burning condition, reaches the object of fire extinguishing.
The generation of foam is mainly through in cylindrical shell, acid solution is mixed with alkaline solution chemical reaction occurs, the foam generated extrudes nozzle, eject and carry out putting out a fire, but the mixed effect of foam generator of the prior art to foam is poor, in actual use, cannot the intensity of a fire in unit are be put out in the short time again, cause efficiency lower, affect rescue efficiency.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of foam proportioning unit, by the structure of modifier inside, realizes, to the efficient generation of foam, meeting fire extinguishing demand.
The technical solution of the utility model is as follows:
Foam proportioning unit, comprise tank body, described tank body is provided with inlet channel, be connected by described inlet channel and the external world, described inlet channel is equipped with check-valves, and in described tank body, be provided with a cavity, described cavity is built with barrier film, described inlet channel is through described cavity, and the other end is through the wall of described tank body; Be provided with a proportioner in the outside of described tank body, described proportioner mouth and described inlet channel are connected, and described proportioner is provided with Pressure gauge, and the diametric plane of described tank body is provided with discharge outlet, safety valve, ball valve and air bleeding valve.
Further, arrange an interlayer at the internal layer of described tank body, form described cavity, described barrier film is positioned at described cavity, and described inlet channel extend in described cavity, described cavity offers a through hole, is connected with described inlet channel.
Beneficial effect: the utility model, can be according to actual needs by above technical scheme.Flexible adjustment foam generates ratio, simultaneously by changing internal structure, contributing to the formation efficiency promoting foam, meeting rescue demand.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
Foam proportioning unit, incorporated by reference to Fig. 1 and Fig. 2, comprises tank body 10, described tank body 10 is provided with inlet channel, is connected by described inlet channel and the external world, described inlet channel is equipped with check-valves 6, in described tank body 10, be provided with a cavity, described cavity is built with barrier film 7.
In order to cavity mentioned in the present embodiment can be understood more clearly, the present embodiment arranges an interlayer at the internal layer of described tank body 10, retain certain gap between the internal face of interlayer and described tank body 10, thus form described cavity, described barrier film 7 is installed in described cavity.
Described inlet channel is extend in described cavity, described cavity offers a through hole 8, described through hole 8 connects another inlet channel, the foam formed can be discharged smoothly.
In order to can to the speed of Inlet and outlet water, and the formation ratio of foam controls, a proportioner 3 is provided with in the outside of described tank body 10, described proportioner 3 mouthfuls and described inlet channel are connected, described proportioner 3 is provided with Pressure gauge 5, hydraulic pressure in described tank body can be monitored by described Pressure gauge 5, the diametric plane of described tank body 10 is provided with discharge outlet 9, safety valve 1, ball valve 2, air bleeding valve 4 and row's foam valve 11, described discharge outlet 9 can be carried out emptying to unnecessary water, air bleeding valve can adjust the air pressure in described tank body 10.
In use procedure, by described inlet channel, the press water of outside is squeezed in described inlet channel, water body is after proportioner 3, tank body 10 is entered inner by described inlet channel, after described barrier film 7, can displace fire foam, fire foam and water are mixed into foam mixing liquid in the ratio of design.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
