Because the two ends of valve rod are connected with the first proportion electro-magnet 11, second proportion electro-magnet 12 respectively, therefore the displacement corresponding to difference (i.e. air-making power) that the displacement that valve rod produces under the combined action of the two is required braking force, electric braking force, lower mask body introduces the control process of this device:
Pressurized state: when braking force is greater than electric braking force needed for electric engineering car, the positive-displacement amount that first proportion electro-magnet 11 exports is greater than the reverse displacement that the second proportion electro-magnet 12 exports, therefore valve rod produces positive-displacement (displacement downward in Fig. 1) under the combined action of the first proportion electro-magnet 11 and the second proportion electro-magnet 12, promote valve rod 6 to move down, make exhaust plug 62 shutoff exhaust valve port 22, air feed spool 61 departs from air feed valve port 21, namely inlet chamber 3 is communicated with outlet chamber 4, and outlet chamber 4 and discharge chamber 5 are isolated.Now, the high pressure air that Air compressor exports flows into air brake equipment through air inlet pipe 31, inlet chamber 3, outlet chamber 4 and freeing pipe 41, realizes the supercharging of air brake equipment.
Decompression state: when braking force is less than electric braking force needed for electric engineering car, the positive-displacement amount that first proportion electro-magnet 11 exports is less than the reverse displacement that the second proportion electro-magnet 12 exports, therefore valve rod produces reverse displacement (in Fig. 1 displacement) upwards under the combined action of the first proportion electro-magnet 11 and the second proportion electro-magnet 12, band ovable valve stem 6 moves up, make exhaust plug 62 depart from exhaust valve port 22, air feed spool 61 shutoff air feed valve port 21, namely inlet chamber 3 is isolated with outlet chamber 4, outlet chamber 4 is communicated with discharge chamber 5.Now, the air of air brake equipment flows into air through freeing pipe 41, outlet chamber 4, valve port of giving vent to anger, discharge chamber 5 and freeing pipe 51, realizes the decompression of air brake equipment.
