The specific embodiment
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
Implement 1
The utility model provides a kind of airport crash fire vehicle foam proportioning unit, comprise device box 10, case lid 17, water pump 12, control valve 14, electrically-controlled valve 4, liquid feed valve 7, cleaning valve 2, hand control valve 8, venturi nozzle 3, water pump 12, in described casing 10, be provided with pipeline, interface and foam inlet 7, pump intake 11, pump outlet 15, power input port 13, cleaning valve gathering hole 1, gathering hole 9, the pipeline of described casing 10 interior settings connects, at pump water inlet 11, be connected respectively at foams mix vacuum line with outlet pipeline 15, on described foams mix vacuum line, control valve 14 is housed, venturi nozzle 3 is housed in foams mix vacuum line, on the pipeline of described foam proportioning system after foam inlet 7, be provided with foam liquid feed valve 5, pipeline after liquid feed valve 5 is divided into three tunnels, one tunnel is automatic control piper, one tunnel is manual control piper, one tunnel is detergent line, and described manual control piper is equipped with hand-operated valve 8, described detergent line is provided with cleaning valve 2, detergent line is connected with pump outlet pipe 15, described automatic control piping system is equipped with electrically-controlled valve 4, the aperture of electrically-controlled valve 4 is distinguishable 90 above different opening angles, electrically-controlled valve 4 is connected with the outer PLC circuit of casing, to realize the aperture of automatic control electric control valve 4, the rear pipeline series connection of the hand-operated valve 8 of described manual control piper and automatically control piper electrically-controlled valve 4, after series connection, pipeline is connected with foams mix vacuum line, described main-supply road, directly for fire-extinguishing apparatus provides the foam mixing liquid meeting the demands, described type foam mixing system vacuum produces pipeline, which is provided with control valve 14, opens valve, can from water pump water outlet pipeline, introduce one press water, by venturi nozzle 3 reducings, accelerate to produce vacuum, suck foam solution, and enter water pump 12 by water feeding of water pump pipeline 12, again mix, described detergent line, is controlled by Manual-cleaning valve 2, and its unlatching is after completing fire extinguishing, water flow is not exerted an influence, and foam feed tube route foam tank is provided with liquid feed valve 5 after drawing, and separates thereafter two forks, one tunnel is automatic control piper, the electrically-controlled valve 4 on it, another road is manual control piper, and hand control valve 8 is housed, and is the second cover hybrid mode of foaming system, the explanation of " negative pressure ", " ring pump ": " negative pressure " refers to that foam dope is obtaining lower than the negative pressure of atmospheric pressure of producing by venturi nozzle, " ring pump " refers to that from pumping line pass, going out one mixed liquor mixes with foam dope at venturi nozzle 3, returning water pump 12 dilutes, exports, formation is around the circulation of water pump, the continuously ratio that completes is mixed, first all spraying equipment working flows of airport crash fire vehicle are demarcated, generally this is to lift a finger: such as being equipped with PP80 type big gun on car, its metered flow is exactly a datum 80L/s, its metered flow of PQ8 foam gun is exactly 8L/s, the flow of each spraying equipment is inputted to PLC in advance, to being installed on the electrically-controlled valve of foam feed liquor pipeline, demarcate, determine the corresponding relation of aperture and flow, common distinguishable 90 above different opening angles, and data are inputted to PLC, the duty of each spraying equipment can be inputted PLC by corresponding button by signal by user, PLC superposes in running order equipment flow calculate total flow according to signal condition, PLC, according to the total flow value of the previously selected mixing ratio of user, above-mentioned calculating and electric control valve respective streams value, by corresponding valve opening angle control gate aperture, thereby realizes the correct mixing ratio that there is no flowmeter.
The airport crash fire vehicle structure that the utility model is installed fully automatic system is simpler, and owing to there is no the cause of flowmeter, reliability is higher, and the range of choice of water pump is wider, more adapts to the needs of China's current various places economic development difference.
