Description
Technical field
The utility model is related to technical field of fire control, more particularly to a kind of foams mix device of foam liquid supply vehicle.
Background technology
In numerous fire, the fire quantity such as petrochemical industry class is continuously increased, and existing fire brigade mostly uses city and advocates war foam firefighting
Vehicle is put out a fire, but the vehicle is chiefly used in city, and the volume of water pot and foam tank is smaller, so needing large-tonnage water tender and foam feed flow
The supply of vehicle, traditional solution are that the water of large-tonnage water tender is fed in the water pot of main-battle firefighting truck, foam feed flow
Foam dope is fed in the foam tank of main-battle firefighting truck by vehicle, and then main-battle firefighting truck itself carries out foams mix to spray again
Penetrate foam fire-fighting.
The feed flow fire fighting truck of domestic all producers supplies without automatic foam scale mixer for simple foam at present
To form, in complicated fire behavior, need to put out a fire for a long time, the foam solution of usual foam vehicle provisioned in fire brigade will appear
Inadequate phenomenon, it is necessary to which foam liquid supply vehicle is fed.There is following several respects disadvantage relative to the utility model：
(1) foam liquid supply vehicle needs to go deep into scene of fire First Line progress foam solution supply；
(2) since foam dope to be first poured into the foam tank of main-battle firefighting truck, then equal water tenders feed water pot
Foam fire-fighting could be carried out after good, the evolutionary operation time is longer, when can be delayed valuable fire extinguishing for fire-fighting fire extinguishing operation
Between；
(3) it is common water-tank lorry if the one non-foam fire fighting truck of line fire fighting truck of front, will be unable to progress foam jet and go out
Fire.
Utility model content
The purpose of this utility model is to provide a kind of foams mix device of foam liquid supply vehicle, to solve to need in the prior art
Foam dope is first poured into the foam tank of main-battle firefighting truck, then could be steeped after waiting water tenders to feed water pot
Foam is put out a fire, and the evolutionary operation time is longer, the problem of valuable attack time can be delayed for fire-fighting fire extinguishing operation.
In order to solve the above technical problems, the utility model provides a kind of foams mix device of foam liquid supply vehicle, including
Foam pump, straight section water lines, foam flowmeter, the first electric proportional-regulation valve and the second electric proportional-regulation valve, the foam
The outlet of pump passes sequentially through the side wall of the foam flowmeter and first electric proportional-regulation valve and the straight section water lines
On connector connection, the foam flowmeter with the foam pump outlet connection one end pass through the described second electronic ratio
Regulating valve is connect with the entrance of the foam pump.
Preferably, water ga(u)ge and pressure sensor are provided in the straight section water lines.
Preferably, first electric proportional-regulation valve and the second electric proportional-regulation valve are proportioning valve.
The utility model can be by the conveying water band of water tanker after connecting the pipeline of foam liquid supply vehicle, foam feed flow
Vehicle is directly injected foam dope by preset froth ratio, and mixed liquor is transported to front main-battle firefighting truck water and is pumped into water again
Mouthful, main-battle firefighting truck directly carries out coupling spray foam operation fire extinguishing.Therefore, foam liquid supply vehicle need not scene of fire most before
End carries out foam dope supply, can directly carry out foam injection in scene of a fire periphery, release the limitation of narrow landform；Simplify operation
Step is greatly improved the speed of front main-battle firefighting truck foam fire-fighting；Mixed liquor is directly injected into main-battle firefighting truck water and is pumped into
The mouth of a river carries out coupling operation, improves extinguishing property；Even if the non-foam truck of advocating war in front, it is common triple, also may be used
It is put out a fire with direct spray foam.
Other than objects, features and advantages described above, the utility model also has other purposes, feature and excellent
Point.The utility model will be described in further detail below.
