Reference numeral among the figure: 1-foam solution container, the 2-water source, 3-draws bubble pipe, 4-pump water inlet, the 5-water pump, 6-Foam switch valve handle, 7-water valve handle, 8-trace, 9-Foam switch valve, 10-water valve, 11-induction tunnel, the 12-nozzle, 13-aqueduct, 14-flow control valve, 15-foam awl, 16-annular dividing plate, 17-connecting rod, the 18-back-moving spring, 19-push pedal, 20-pumping line.
The specific embodiment
Structural representation of the present utility model is seen accompanying drawing, comprises drawing bubble pipe 3, aqueduct 13, induction tunnel 11, and an end that wherein draws bubble pipe 3 links to each other with foam solution container 1, and its other end links to each other with the inlet of induction tunnel 11; Aqueduct 13 1 ends link to each other with pumping line 20, and its other end links to each other with the inlet of induction tunnel 11, and the end that aqueduct 13 links to each other with induction tunnel 11 is provided with the nozzle 12 over against induction tunnel 11; Induction tunnel 11 outlets are arranged on pump water inlet 4 tube walls; Draw on the bubble pipe 3 and be disposed with Foam switch valve 9 and flow control valve, flow control valve comprises push pedal 19, annular dividing plate 14, conical foam awl 15, connecting rod 17 and back-moving spring 18, wherein push pedal 19 is arranged on the pumping line 20, annular dividing plate 14 is arranged on and draws on bubble pipe 3 inwalls, conical foam awl 15 is arranged on and draws in the bubble pipe 3 and its periphery can match with annular dividing plate 14, connecting rod 17 push pedal 19 and the foam awl 15 that is used to be connected, back-moving spring 18 is enclosed within on the connecting rod 14; Aqueduct 13 is provided with water valve 10, is provided with linkage between water valve 10 and the Foam switch valve 9; Linkage is the trace 8 of two ends difference hinge at water valve handle 7 middle parts and Foam switch valve handle 6 middle parts.
The utility model principle:
Drawing the effect of steeping pipe is that foam solution is imported to induction tunnel from the foam solution container; The effect of aqueduct is that the water in the pumping line is imported to induction tunnel; The effect of induction tunnel is with foam solution and water mixes and mixed liquid is sent in the pump water inlet; The effect of nozzle is to form high-velocity flow in induction tunnel; The effect of flow control valve is to utilize hydraulic pressure in the water pump to control the flow of foam solution, and the flow that makes foam solution and the hydraulic pressure of the water pump just flow of water become certain ratio; The effect of back-moving spring is to guarantee to control when hydraulic pressure reduces the foam awl to move downward, and reduces the flow of foam solution; The effect of trace is to guarantee that foam solution and water can import in the induction tunnel as far as possible simultaneously.
At first, under low speed, move water pump, water enters aqueduct from the outlet pipe of water pump, the pressure of the outlet pipe of water pump generation simultaneously promotes push pedal and moves upward, owing to there is the reaction of back-moving spring to exist, the distance that push pedal moves upward is directly proportional with hydraulic pressure, drives foam and bores relative to the annular dividing plate corresponding moving upwards arranged thereby push pedal drives connecting rod.When needing foam fire-fighting, the Foam switch valve handle of leaving behind, Foam switch valve and water valve are opened under the effect of trace simultaneously, make press water in the aqueduct from the nozzle ejection to the induction tunnel, enter pump water inlet then.Air in the induction tunnel is taken away by the high speed pressure current of nozzle ejection, air pressure in the induction tunnel is far below atmospheric pressure like this, and the foam solution in the foam solution container is aspirated by this air pressure, from drawing the bubble pipe behind the Foam switch valve, gap through between foam awl and the annular dividing plate enters induction tunnel at last.Foam solution and water mix in induction tunnel, enter water pump jointly, fully mix once more at water pump inner foam liquid and water, and the outlet pipe through water pump is transported to water cannon again, and then mixes with air in water cannon, the last injected fire extinguishing of going out.
Because the pressure of pumping line is bored the annulus area of controlling between foam awl and the annular dividing plate by push pedal, connecting rod and foam, just the flow of water has determined to enter the foam solution flow of water pump, no matter how the flow of water pump changes like this, foams mix maintains in certain scope than all the time, and the mixing ratio scope of the utility model product is generally 6%～7%.
