Description
Technical field
The utility model belongs to the fire-fighting equipment technical field, is specifically related to a kind of medium expansion foam generator.
Background technology
Foam-generating device is one of key component in the froth fire extinguishing system, according to use occasion is different with using method multiple variety classes is arranged.And the medium expansion foam generator of producing at present is because structural design is unreasonable, cause its coefficient of foaming little, fire-fighting efficiency is low, and installing/dismounting is dumb, be not suitable for the fire-fighting equipment installation and transportation with big flow, can not reach national froth fire extinguishing system and the requirement of parts general technical specifications simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of medium expansion foam generator at above-mentioned deficiency of the prior art, its simple in structure and easy installation and removal, and coefficient of foaming is big simultaneously, the fire-fighting efficiency height.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of medium expansion foam generator, comprise sectional shelf-unit, the straight tube of foaming, spurt mouth and deflector-type nozzle, it is characterized in that: described deflector-type nozzle is installed in the sectional shelf-unit front end, be provided with spiral baffle in the described deflector-type nozzle, described sectional shelf-unit is by flange, riser and adapter connect to form, described riser front end is welded in the adapter, described adapter is threaded with deflector-type nozzle, fixedly connected with the straight tube of flange and the foaming that is arranged on described sectional shelf-unit rear end by bolt in described riser rear end, the straight tube inner chamber of described foaming is provided with foam screen, the straight tube rear end of described foaming is provided with and spurts mouth, and spurts mouthful with the straight tube of foaming and spurt and mouthful be bolted to connection.
Described spiral baffle is made up of three guide vanes that are provided with along axis direction, and angle all at 45 between the described guide vane.
Described flange is disposed with explosion plate and pressing plate on the right side, and described explosion plate and pressing plate and flange are bolted to connection.
The utility model compared with prior art has the following advantages: the utility model is simple in structure and coefficient of foaming is big, it is by being provided with spiral baffle in deflector-type nozzle, increase area and the atomizing effect of foam mixing liquid when nozzle sprays, and then improved fire-fighting efficiency; Simultaneously, take over the straight tube that is threaded and foams with deflector-type nozzle with sectional shelf-unit with spurt mouth and all be bolted to connection, make whole device easy installation and removal.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
A kind of medium expansion foam generator as shown in Figure 1, comprise sectional shelf-unit 3, the straight tube 5 of foaming, spurt mouth 7 and deflector-type nozzle 2, described deflector-type nozzle 2 is installed in sectional shelf-unit 3 front ends, be provided with spiral baffle 11 in the described deflector-type nozzle 2, described sectional shelf-unit 3 is by flange 4, riser 10 and adapter 1 connect to form, described riser 10 front ends are welded on to be taken on 1, described adapter 1 is threaded with deflector-type nozzle 2, fixedly connected with the straight tube 5 of flange 4 and the foaming that is arranged on described sectional shelf-unit 3 rear ends by bolt in described riser 10 rear ends, the straight tube of described foaming 5 inner chambers are provided with foam screen 6, the straight tube of described foaming 5 rear ends are provided with spurts mouthfuls 7, and spurts mouthfuls 7 with the straight tube 5 of foaming with spurt mouthfuls 7 and be bolted to connection.
In the present embodiment, spiral baffle 11 is made up of three guide vanes that are provided with along axis direction, and angle all at 45 between the described guide vane, has increased area and the atomizing effect of foam mixing liquid when nozzle sprays, and then has improved fire-fighting efficiency; Be disposed with explosion plate 8 and pressing plate 9 on flange 4 right sides, and described explosion plate 8 and pressing plate 9 is bolted to connection with flange 4;
Simultaneously, it is the straight tube of foaming of φ 100-φ 300X1500, φ 200-φ 500X1500 or φ 400-φ 800X1500 that the straight tube 5 of foaming can adopt specification according to the foam solution flow, and be connected on the sectional shelf-unit 3 with the bolt of M8X15, and will spurt mouthfuls 7 with the bolt of M6X20 and fix, make things convenient for installing/dismounting with straight tube 5 of foaming and foam screen.
Operation principle of the present utility model is: when foam mixing liquid flows through generator deflector-type nozzle 2, form the dispersed jet of diffusion, around it, produce negative pressure, make the straight tube 5 of foaming suck a large amount of air and form air, in the air input basin, drop down along tank skin, topped reposefully on the burning liquid level and form froth bed, secluding air, absorption heat, thus fire is put out.To sum up, the utility model coefficient of foaming height, can be aided with the supporting use of inline inductor with foam truck, triple and portable fire pump with engine, be mainly used in put out a fire to save life and property category-B liquid fire and solid matter fire etc., can be widely used in places such as warehouse, oil depot, colliery, chemical industry workshop, boats and ships, garage, hangar.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
