Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of portable electric wind-force foam spray, comprise shell 1, bubble chamber 2, proportioner 3, power supply 4, foam gun 5, controller 6 and blower fan 7, bubble chamber 2, proportioner 3, power supply 4 and blower fan 7 is fixedly mounted successively from top to bottom in shell 1, blower fan 7 output connects foam gun 5 by pipeline, mount controller 6 in foam gun 5, described bubble chamber 2 is connected by pipeline with proportioner 3, proportioner 3 is connected to the blender in foam gun 5 by pipeline, and blender and all external pressure water source 8 of proportioner 3.
Described power supply 4 is lithium battery.Described shell 1 is provided with backrest 9, and backrest 9 is provided with braces 10.
In use, controlled by controller 6 pairs of bubble chambers 2, proportioner 3, blower fan 7 and foam gun 5.Blowing agent in bubble chamber 2 and external press water enter proportioner 3 simultaneously and mix, then by Cemented filling to the blender in foam gun 5, in blender, input external press water simultaneously, the foam that blender sprays by blower fan 7 work air-supply ejects from foam gun 5 port of export and catches fire object, isolated air enters into the body surface that catches fire, thus stop burning away of object, reach the object of fire extinguishing.
See Fig. 3 and Fig. 4, above-mentioned proportioner 3 comprises shell body 3-1, water inlet pipe, foaming agent carrier pipe, Venturi tube 3-2, blending bin 3-3, first tee pipe coupling 3-4, second tee pipe coupling 3-5, Linear flow control valve 3-6 and mixed liquor carrier pipe 3-7, described blending bin 3-3 is fixed in shell body 3-1, Venturi tube 3-2 level crosses blending bin 3-3, this Venturi tube 3-2 is assembled by two parts, form the mating surface 3-16 be in blending bin 3-3 between the two sections, described shell body 3-1 is provided with water inlet pipe installing port 3-8, foaming agent carrier pipe installing port 3-9 and mixed liquor carrier pipe installing port 3-10, described water inlet pipe comprises the first water inlet pipe 3-11 and the second water inlet pipe 3-12, one end of first water inlet pipe 3-11 is connected with pressure water source 8, the other end is stretched in shell body 3-1 by water inlet pipe installing port 3-8 and is connected with the first tee pipe coupling 3-4, second water inlet pipe 3-12 one end is connected with the first tee pipe coupling 3-4, the other end is connected with one end of Venturi tube 3-2, the other end of Venturi tube 3-2 is connected with one end of mixed liquor carrier pipe 3-7, the other end of mixed liquor carrier pipe 3-7 stretches out shell body 3-1 by mixed liquor carrier pipe installing port 3-10 and is connected to blender in foam gun 5.Described foaming agent carrier pipe comprises the first foaming agent carrier pipe 3-13 and the second foaming agent carrier pipe 3-14, first foaming agent carrier pipe 3-13 one end bubble chamber 2 connects, the other end is stretched in shell body 3-1 by foaming agent carrier pipe installing port 3-9 and is connected with the second tee pipe coupling 3-5, and the second foaming agent carrier pipe 3-14 is installed between the second tee pipe coupling 3-5 and blending bin 3-3.Water inlet pipe 3-15 is installed between the first tee pipe coupling 3-4 and the second tee pipe coupling 3-5.First foaming agent carrier pipe 3-13 installs Linear flow control valve 3-6.
The caliber of described water inlet pipe 3-15 is less than water inlet pipe caliber and foaming agent carrier pipe caliber, thus improves the hydraulic pressure of 3-15 in water inlet pipe, strengthens the mixed effect of fire water and foaming agent.
In use, press water enters from water inlet pipe, and foaming agent enters from foaming agent carrier pipe.According to venturi operation principle, there is the fluid of certain pressure by can produce the negative pressure of certain pressure after Venturi tube at back pressure place, the pressure in mixed liquor carrier pipe exit is all the time lower than the pressure of water inlet pipe and foaming agent carrier pipe, foaming agent and pressure flow press the direction flowing shown in arrow (as shown in Figure 3 all the time, solid arrow represents pressure flow direction, and dotted arrow represents foaming agent flow direction).Press water flows into foaming agent carrier pipe by water inlet pipe and tentatively mixes with foaming agent, in the process that the foam solution of preliminary mixing flows to blending bin along foaming agent carrier pipe, repeatedly carry out mixed diluting with press water, after entering blending bin, foam solution by the mating surface in the middle part of Venturi tube to enter in Venturi tube further with press water mixed diluting, export the blender in foam gun to finally by mixed liquor carrier pipe.
Aforementioned proportion device utilizes venturi principle to ensure, and foaming agent and water is not when flowing by constant flow rate when external pressure fluctuations.Foaming agent flow can be finely tuned arbitrarily on request to adopt flow control valve to ensure, to reach the best foam solution of ratio on request, thus gives full play to the best extinguishing effect of foaming agent.Can make that foaming agent and press water are repeatedly mixed dilute, thus foaming agent is evenly mixed fully with press water, the coefficient of foaming of the foam solution of guarantee low expansion foam rifle, significantly improve to close or reach the higher limit (20 times of blowing ratios) of standard-required.
A kind of control method of above-mentioned spray, powered to proportioner, blower fan and controller by power supply, controller controls bubble chamber and input blowing agent in proportioner, pressure water source is to input pressure water in proportioner simultaneously, press water repeatedly mixes in proportioner with blowing agent, blowing agent and press water are mixed generation foam by proportioner, then Pipeline transport is in the blender of foam gun, simultaneously to input pressure water in blender, press water and foam mix by blender, spray in foam gun after completing.Blower fan provides air for blowing agent and press water are mixed into foam solution, and foam solution is formed foam stream from the ejection of foam gun output.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
