It is unable to satisfy the demand of large-scale and ultra-large type fire-fighting foams big gun equipment, cannot be used in large-scale petrochemical fire, to accordingly advise
The mixing arrangement product blank of mould becomes the fire-fighting bottleneck of Domestic Petrochemical Enterprises large size liquid fire.
It is mobility strong, easy to operate for this purpose, trailer or cart can be provided in by developing one kind, it is with fire-fighting pressure water supply
Power, foam solution injection vibration means for main pipe for supplying water is formed to big flow water-foam mixing liquid dress of regulation mixed proportion using pressure difference
It is highly important for setting.
Summary of the invention
The utility model breaches the problem of the prior art, devise it is a kind of it is inexpensive, small in size, supplied water with fire-fighting pressure
For power, mobility strong and easy to operate big flow foam solution mixing arrangement.
In order to achieve the above object, the utility model devises a kind of big flow water-foam solution mixing arrangement, including water wheels
Machine, clutch and foam pump, it is characterised in that: one end of foam solution input pipe is connected with one end of valve one, and foam solution is defeated
Enter the other end connection foam sap cavity of pipe, the other end of valve one is divided into three tunnels and one end of pipeline and valve two, bubble is respectively adopted
The arrival end of foam liquid pump, one end of overflow valve are connected, and the other end of valve two is connected with the one end for rinsing water inlet pipe, flushing water
The other end of input pipe is connected to outlet end and overflow valve of the main-supply road above the side of water inlet end, foam pump
Intermediate ends are connected, and the other end of overflow valve is connected with main-supply road close to the side of water outlet using another pipeline, the master
The hydraulic turbine is equipped in water supply pipe, the side of foam pump passes through shaft coupling and clutch and then and hydraulic turbine phase using transmission shaft
Even.
For the hydraulic turbine between water inlet end and water outlet, rotation direction is consistent with the rotation direction of foam pump.
The water inlet end position on the main-supply road is higher than water outlet end position.
The clutch, valve one and valve two are connected with external control electronic box.
Compared with prior art, the utility model structure is simple for the utility model, small in size, at low cost, can be placed on
It is moved on trailer, has good mobility for fire processing, and when valve one is opened and closes clutch, it can be with
Foam liquid is formed out, supports the use of fixed froth installation, when valve one is closed, and valve two is opened, vibration means for main pipe for supplying water road
Water, which enters foam pump pipeline, can clean whole device.Holdback clutch, closure valve one and valve two can be realized merely
The function of water supply realizes that usage mode may be selected in two kinds of functions of an equipment；The internal combustion engine as device power source is eliminated, and
It is using fire fighting hydraulic pressure as power source, using the hybrid mode for having pressure difference, allowing whole device, not only foam flow surpasses
200L/s is crossed, and has prevented the pollution of internal combustion engine generation and the drawback of mobility difference.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 be in the utility model F to cross-sectional view.
Specific embodiment
The utility model is further described in conjunction with attached drawing.
Referring to Fig. 1 ~ 2, the utility model devises a kind of using pressure water supply as power, is infused foam solution using pressure difference
Enter big flow water-foam mixing liquid device that vibration means for main pipe for supplying water forms regulation mixed proportion, including the hydraulic turbine, clutch and bubble
One end of foam liquid pump, foam solution input pipe 1 is connected with one end of valve 1, and the other end of foam solution input pipe 1 connects foam solution
Chamber, the other end of valve 1 are divided into three tunnels and one end of pipeline and valve 23, the arrival end of foam pump 4, overflow are respectively adopted
One end of valve 8 is connected, and the other end of valve 23 is connected with the one end for rinsing water inlet pipe 5, rinses the other end of water inlet pipe 5
