In the concrete scheme, be provided with first elastic plate 71 in the above-mentioned valve body 2, the top board of discharge chamber 5 is second elastic plate 72, the perisporium of first elastic plate 71 and second elastic plate 72 is all captiveed joint with valve body 2 inwalls, valve rod 6 runs through the middle part of first elastic plate 71 and second elastic plate 72, and first elastic plate 71, second elastic plate 72 and valve body 2 inwall threes surround pressure feedback chamber 7.
Adopt this structure, as shown in Figure 1, when valve rod 6 produces positive-displacement under the force action of two proportion electro-magnets, promote valve rod 6 move down, open air feed valve port 21, when closing exhaust valve port 22, make the middle part of win elastic plate 71 and second elastic plate 72 produce downward displacement, i.e. the downward tensile deformation of pressure feedback chamber 7 whole generations.In the pressurization, compressed-air actuated part in the freeing pipe 41 flows into air brake equipment, another part is by feedback pipe 73 feed pressure feedback cavity 7, pressure feedback chamber 7 pressure inside are constantly increased, when the pressure in pressure feedback chamber 7 increases to its thrust that makes progress and equals making a concerted effort of first proportion electro-magnet 11 and second proportion electro-magnet 12, promote first elastic plate 71, the center of second elastic plate 72 moves up, up to first elastic plate 71, second elastic plate, 72 integral body return to horizontality, as shown in Figure 3, this moment air feed spool 61 shutoff air feed valve ports 21, exhaust plug 62 shutoff exhaust valve ports 22, like this, it is current constant that air pressure in the air brake equipment keeps, the voltage stabilizing state when namely being in supercharging.
In like manner, as shown in Figure 2, when valve rod 6 produces reverse displacement under the force action of two proportion electro-magnets, promoting valve rod 6 moves up, close air feed valve port 21, when opening exhaust valve port 22, make the middle part of win elastic plate 71 and second elastic plate 72 produce displacement upwards, i.e. the pressure feedback chamber 7 whole tensile deformations upwards that produce.In the decompression process, pressurized air part in the freeing pipe 41 flows into discharge chamber 5, another part is by feedback pipe 73 feed pressure feedback cavity 7, pressure feedback chamber 7 pressure inside are constantly increased, when the pressure in pressure feedback chamber 7 increases to its downward thrust and equals making a concerted effort of first proportion electro-magnet 11 and second proportion electro-magnet 12, promote first elastic plate 71, the center of second elastic plate 72 moves up and down, up to first elastic plate 71, second elastic plate, 72 integral body return to horizontality, as shown in Figure 3, this moment air feed spool 61 shutoff air feed valve ports 21, exhaust plug 62 shutoff exhaust valve ports 22, like this, it is current constant that air pressure in the air brake equipment keeps, the voltage stabilizing state when namely being in decompression.
This shows that the air brake control setup in above-mentioned employing pressure feedback chamber 7 can be realized automatic voltage regulation in the process of air brake, guarantee the working stability of air brake.Can expect, above-mentioned pressure feedback chamber 7 is not limited in said structure, for example, first dividing plate and second partition can be set in valve body 2, the two all with the perisporium sliding block joint of valve body 2, first dividing plate, second partition and valve body 2 internal perisporiums surround above-mentioned pressure feedback chamber 7.Adopt this structure, can in the process of air brake, realize automatic voltage regulation equally.But this pressure feedback chamber 7 relates to the gravity problem of first dividing plate, second partition and valve rod, therefore, for the elasticity modulus of first elastomeric element 81 stricter requirement is arranged, and first proportion electro-magnet 11 is stressed comparatively complicated.In addition, above-mentioned pressure feedback chamber also not only for discharge chamber 5 adjacency, also it can be arranged at inlet chamber 3 and connect.
In the concrete scheme, above-mentioned first elastomeric element 81 can be specially spring.Adopt spring to connect the strong and proportion electro-magnet of pressure feedback as first elastomeric element 81, can guarantee the working stability of air brake control setup, and have lower-cost characteristics.Certainly, first elastomeric element 81 can also adopt other elastomeric materials such as rubber.

In the another kind of specific embodiment, armature 111 bottoms of first proportion electro-magnet can be connected with first connecting rod 112 and first piston 113, the first elastomeric elements 81 are connected in first piston 113 bottoms.
Adopt this structure, in the working process, the thrust of first proportion electro-magnet 11 at first passes to first connecting rod 112, and the displacement of first connecting rod 112 drives first piston 113 and slides at valve body 2 inwalls, and the displacement of first piston 113 drives parts such as first elastomeric element 81, valve rod 6 again and moves.Because the periphery wall of piston 13 and the internal perisporium sliding connection of valve body 2, therefore first piston 113 has certain directional tagging in moving process, thereby guarantee that parts such as first elastomeric element 81, valve rod 6 can move along the central axis of valve body 2, avoid valve rod 6 banking motions to cause air feed valve port 21 or exhaust valve port 22 to have the generation of wild effects such as gas leakage, further guarantee the working stability of air brake control setup.
In the another kind of specific embodiment, as shown in Figure 1, the base plate of inlet chamber 3 is the 3rd elastic plate 32, the perisporium of the 3rd elastic plate 32 is captiveed joint with valve body 2 inwalls, armature 121 tops of second proportion electro-magnet are connected with second connecting rod 122 and second piston, 123, the second pistons 123 are connected with the 3rd elastic plate 32 by second elastomeric element 82.
Similar ground adopts this structure, and second piston 123 also has certain directional tagging in moving process, guarantees that further parts such as second elastomeric element 82, valve rod can guarantee working stability along the axial-movement of valve body.
In the another kind of specific embodiment, above-mentioned valve body 2 is provided with first air extractor vent 23 at first cavity wall that surrounds with first elastic plate 71, first piston 113 threes, valve body 2 be provided with second air extractor vent, 24, the first air extractor vents 23 with first piston 113 the two second cavity wall that surround, second air extractor vent 24 is communicated with atmosphere.
Adopt this structure, make the cavity of winning remain the pressure identical with barometric pressure with second cavity, avoid because first elastic plate 71 causes the pressure of first cavity to change in compression and stretching, avoid guaranteeing working stability and the reliability of air brake control setup because piston 13 causes the pressure of this chamber to change in upper and lower moving process.
Similarly in the scheme, valve body 2 is provided with the 3rd air extractor vent 25 at the 3rd cavity wall that surrounds with the 3rd elastic plate 32, second piston, 123 threes, valve body be provided with four-way pore 26, the three air extractor vents 25 with second piston, 123 the two the 3rd cavity wall that surround, four-way pore 26 all is communicated with atmosphere.
Identical with the technique effect of first cavity and second cavity, adopt this structure can guarantee that the pressure of the 3rd cavity and the 4th cavity remains barometric pressure, further guarantees working stability and the reliability of air brake equipment.
In addition, the present invention also provides a kind of sky electric composite braking system, comprises electric braking control setup and air brake control setup; The air brake control setup adopts air brake control setup as above.
