Description
Technical field
The present invention relates to a kind of fire-fighting equipment, and in particular to a kind of big flow CAFS.
Background technology
Compressed air bubble system (CAFS) is applied to fire-fighting domain, can fully refine foam mixing liquid and foamed, steeps
Foam contains substantial amounts of pressure-air, enhances extinguishing chemical penetrating power and adhesive ability, and its extinguishing effect improves compared with pure water
More than 10 times.Because foam mixing liquid contains compressed air, water consumption is small, fire-fighting operation time length；The weight of water band during work
More than 50% can be reduced, fire extinguishing mobility is high.The general principle of existing CAFS technologies is：With water pump and foam pump by water and bubble
Foam liquid is mixed in proportion, forms foam mixing liquid, and high pressure air is then injected in hybrid chamber, forms compressed air bubble
Foam, then ejected through fire monitor or fire-fighting lance, realize fire extinguishing and thermal insulation protection function.
Existing CAFS technologies using foam pump due to conveying foam solution, due to B class A foam As liquid particularly fluoroprotein foam
Liquid has viscosity larger, and impurity is more, easily causes foam pump filter net jam；It is residual as do not rinsed in time after the completion of fire-fighting operation
Remaining foam solution is dry and hard will to cause mating surface in foam pump to interfere, and cause stall.The above situation will cause fire fighting truck not work.Separately
Outside, limited by fire fighting truck space, power and manufacturing cost, the less foam pump of flow can only be selected on fire fighting truck.And B classes
The mixing of foam solution and water is bigger, and foam flow quantity is larger when spraying B class A foam As, therefore foam pump can only meet medium-small flow
The demand of B class CAFS systems, it is impossible to meet the fire-fighting demand of large-sized fire.
Therefore, necessary on the basis of prior art, research and development are a kind of reasonable in design, easy to use, can expire
The demand of sufficient big flow B classes CAFS systems, fire-fighting operation ability is strong, and extinguishing property is good, the high big flow compressed air of reliability
Foaming system.
The content of the invention
Goal of the invention：The invention aims to solve the deficiencies in the prior art, there is provided and it is a kind of reasonable in design, make
With conveniently, can meet the needs of big flow B class CAFS systems, fire-fighting operation ability is strong, and extinguishing property is good, the high big stream of reliability
Measure CAFS.
Technical scheme：In order to realize the above object the technical scheme that the present invention takes is：
A kind of big flow CAFS, it is characterised in that it includes：Water inlet, the water being connected with water inlet
Pump and Venturi tube, the metering valve being connected with Venturi tube, the foam flow meters being connected with metering valve and with foam flow quantity
The connected concentrated tank of meter；Water pump is connected with main meter, check valve and blender successively by pipeline；Described blender point
It is not connected with air compressor, fire monitor, the first fire-fighting lance and the second fire-fighting lance；
The second stop valve is installed between described blender and fire monitor；Described blender and the first fire-fighting lance it
Between the 3rd stop valve is installed；The 4th stop valve is installed between described blender and the second fire-fighting lance.
Preferably, above-described big flow CAFS, foam flow meters and concentrated tank
Between the first stop valve is installed.
Preferably, above-described big flow CAFS, foam flow meters by pipeline with
Main meter is connected；5th stop valve is installed on the pipeline between foam flow meters and main meter.
Preferably, above-described big flow CAFS, Venturi tube pass through with main meter
Pipeline is connected, and the 6th stop valve is provided with pipeline.
As other preferred schemes, above-described big flow CAFS, of fire monitor and anti-hydraulic giant
Number can design according to being actually needed.
Big flow CAFS of the present invention, during real work, the first stop valve, the 6th stop valve are beaten
Open, the 5th stop valve is closed；Water pump is drawn water by water inlet, and water comes after liquid mixes to be formed foam mixing liquid, water with Venturi tube
The foam mixing liquid of pump output is divided into two-way, wherein entering Venturi tube by the 6th stop valve all the way；Produced in Venturi effect
Under raw suction function, foam solution is inhaled into literary mound by foam solution entrance, the first stop valve, foam flow meters, metering valve
In manage, be mixed into high concentration foam mixing liquid, mixed-liquor return to pump entrance pipeline with foam mixing liquid；Water pump exports another
All the way foam mixing liquid by main meter, check valve, into blender, mixed with the pressure-air from air compressor
Close, form compressed-air foam；Compressed-air foam is controlled by stop valve, by fire monitor or fire-fighting lance individually injection or same
When spray.
The 6th stop valve is closed in above-mentioned operating mode, negative pressure is disappeared in Venturi tube, and foam solution is no longer entered by Venturi tube
Enter the inlet pipeline of water pump, system is worked with pure water pattern, meets the needs of operating modes such as water delivery, foam mixing liquid flushing of pipeline.
As opened the 5th stop valve again, current will be by the 5th stop valve, foam flow meters, Venturi tube, to foam solution through pipe
Road is rinsed, to avoid corrosion of the residual foam liquid to system pipeline.
Beneficial effect：Compared to the prior art big flow CAFS of the present invention has following excellent
Point：
Big flow CAFS provided by the present invention, it is reasonable in design, it is easy to use, it can meet to flow greatly
The demand of B classes compressed air bubble system is measured, fire-fighting operation ability is strong, and extinguishing property is good, can prevent foam pump filter net jam, uses
Long lifespan, it is practical.
The present invention passes through experiment sieving, especially substitutes foam pump auto-pumping foam solution using Venturi tube, and foam solution is defeated
For outflow up to more than 400L/min, this is that conventional vehicle-mounted foam pump is unapproachable, can meet big flow B class CAFS systems
Demand；Venturi tube structure is simple, latus rectum is big, can avoid blocking completely, stall phenomena such as, functional reliability is high, various foams
Liquid can use so that cheap B class A foam A liquid application scenario is more extensive, and economy is more preferable；And the present invention is by excellent
The control system of design is selected, by comparing foam solution flowmeter measurements and main meter measured value, valve opening is measured in control, from
And foam flow quantity is accurately controlled, the mixing ratio of itself and water is remained setting value, ensure optimal extinguishing effect.
