Technical field
The present invention relates to a kind of airport ground facilities, is a kind of de-icing liquor proportional control apparatus specifically, adjusts the blending ratio of deicing liquid and water when being used for the aircraft deicing vehicle operation.
Background technology
As everyone knows, the function of removing ice machine is that the deicing liquid that will be heated to uniform temperature is sprayed onto aircraft surfaces through spray gun and carries out the deicing operation, according to the freeze difference of situation of ambient temperature and aircraft, can adopt different deicing liquid concentration and temperature.
At present, the deicing liquid sprinkler mainly is made up of single deicing liquid pipeline, and it is characterized in that: pipeline is simple; Its deficiency is: deicing liquid concentration can only be regulated by adding formula of liquid, the inconvenience of deicing liquid concentration adjustment.
Because existing deicing liquid sprinkler exists deicing liquid concentration to regulate by adding formula of liquid, there is significant limitation in the deficiency of deicing liquid concentration adjustment inconvenience during use, can not satisfy except that ice machine and regulate the requirement of deicing liquid concentration when the deicing operation at random
Summary of the invention
Exist deicing liquid concentration to regulate in order to overcome existing deicing liquid sprinkler, the deficiency of deicing liquid concentration adjustment inconvenience by liquid feeding.The object of the present invention is to provide a kind of de-icing liquor proportional control apparatus, regulate the deicing liquid concentration ratio when being used for removing the ice machine operation, the satisfied ice machine that removes is regulated the requirement of deicing liquid concentration at random when the deicing operation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of de-icing liquor proportional control apparatus, comprise the deicing liquid pipeline, its principal character is: on the deicing liquid pipeline flow count mouthful with the deicing liquid pipeline on controllable capacity pump export and be connected, on the water lines flow count mouthful with water lines on controllable capacity pump export and be connected, deicing liquid pipeline and water lines are in parallel at the exit end of flow counter separately.
The present invention can also realize by following measures: on the deicing liquid pipeline on flow counter and the water lines flow counter exit end be respectively equipped with check valve.The controllable capacity pump arrival end is connected with water tank through filter, ball valve on the water lines.The deicing liquid pipeline is connected with the deicing liquid case through filter, pump orifice and ball valve.The controllable capacity pump exit end is connected with heating arrangement through threeway and check valve on the water lines.Be provided with the deicing liquid aspiration circuit between deicing liquid pipeline and return line.
The invention has the beneficial effects as follows: because deicing liquid sprays pipeline water route in parallel, deicing liquid pipeline and water lines are provided with the flow counter and the controllable capacity pump of interlock, can set the blending ratio that flow parameter is controlled deicing liquid and water by PLC, remove ice machine can be regulated deicing liquid at random according to the varying environment situation when the deicing operation concentration.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the scheme drawing of de-icing liquor proportional control apparatus of the present invention, also is a kind of scheme drawing of embodiment.
Among the figure: 1, deicing liquid pipeline, 2, ball valve, 3, the deicing liquid case, 4, water tank, 5, ball valve, 6, water lines, 7, filter, 8, controllable capacity pump, 9, check valve, 10, threeway, 11, flow counter, 12, check valve, 13, threeway, 14. compression indicators, 15. ball valves, 16, spray gun, 17, check valve, 18, flow counter, 19, the deicing liquid pipeline, 20, threeway, 21, threeway, 22, proportion magnetic valve, 23, threeway, 24, ball valve, 25, check valve, 26 controllable capacity pumps, 27 filters, 28, pump orifice.
The specific embodiment:
In Fig. 1, flow counter 18 inlets are connected with controllable capacity pump 26 outlets on the deicing liquid pipeline 19, flow counter 11 inlets are connected with controllable capacity pump 8 outlets on the water lines 6, deicing liquid pipeline 19 and water lines 6 are in parallel through threeway 13 at the exit end of flow counter 18, flow counter 11 separately, mixing material arrives spray gun 16 through ball valve 15, is provided with compression indicator 14 before the ball valve 15.
The return line that deicing liquid pipeline 19 is made up of the feed flow loop that comprises controllable capacity pump 26, filter 27, pump orifice 28 and deicing liquid pipeline 1, threeway 23 and electromagnetic valve 22 is in parallel through threeway 20; Deicing liquid case 3, ball valve 2, pump orifice 28, filter 27, controllable capacity pump 26, threeway 21, check valve 25, ball valve 24, threeway 23, deicing liquid pipeline 1 and deicing liquid case 3 end to end composition deicing liquid aspiration circuit.
During use, according to weather, the aircraft situation of freezing is selected deicing liquid scale parameter input PLC, proportion magnetic valve is composed with initial value signal, detect flow counter 11 simultaneously, the signal of flow counter 18 feedbacks, PLC is according to flow counter 11, thereby the signal of flow counter 18 is revised the flow of the interior hydraulic oil of aperture modulated pressure pipeline of proportion magnetic valve, controllable capacity pump 8 and controllable capacity pump 26 are along with the size of hydraulic oil pressure changes self rotating speed, water and deicing liquid flow velocity change thereupon, PLC is with flow counter 11, flow counter 18 signals and preset value compare, adjustment through a plurality of cycles, the deicing liquid ratio will be stabilized on the preset proportional value, thereby reach the purpose of accurate ratio deicing liquid.
In ice detachment, if close spray gun, after detecting feedback signal, opens PLC return flow solenoid valve 22, water and deicing liquid are back in water tank and the deicing liquid case separately, same when spray gun is opened after PLC detect closing volume electromagnetic valve behind the signal of feedback, thereby water and deicing liquid mixing then spray from spray gun.
The deicing liquid suction: close ball valve 2, confirm that spray gun is in closed condition, ball valve 24 is in open mode, opens suction flap 28, connects suction hose and also inserts in the deicing liquid that will annotate, opens the suction of suction switch; After suction is finished, close suction switch and ball valve 24, take off suction hose, cover suction flap 28, open ball valve 2.
Because water route in parallel, deicing liquid pipeline and water lines are provided with flow counter and controllable capacity pump, can set the deicing liquid scale parameter by PLC, and the satisfied ice machine that removes is regulated the requirement of deicing liquid concentration at random when the deicing operation.
