Less than the area of the second drive end 31, second blind end 32 is the free end of the cylinder protruded out from the second linkage end 33 to product.
The course of work of the piston control valve is as follows：
When wind is filled to checking cylinder, the first magnetic valve 4 and the second magnetic valve 5 all in power failure state, now the first side
The side passage 172 of passage 171 and second has pressed gas all the time, and first intake adit the 14, first linkage passage 161 is not pressed
Strength body, the second intake adit 15 can receive the air feed from the total wind of vehicle, so as to drive second piston 3 to move down to close air draft
Mouth 13；Meanwhile, the first inner chamber that the total wind of vehicle is input at the first linkage end 23 of first piston 2 by the second linkage passage 162
In 191 so that moved on first piston 2 and open main air outlet 12, now main air inlet 11 is by going out vane groove 183 and first
Connectivity slot 193 is toward the air feed of main air outlet 12.In this case, if the situation of the first magnetic valve 4 and the second magnetic valve 5 keeps not
Become, then constantly fill wind to the checking cylinder being connected at main air outlet 12.
When the piston control valve is in packing state, the first magnetic valve 4 obtains electric, the first side passage 171 and first
Intake adit 14 is connected, to the air feed of the first drive end 21 of first piston 2, now effect of the first piston 2 in pressed gas
Under move down to close main air outlet 12；The first linkage passage 161 is connected with pressed gas and is delivered to the second of second piston 3 simultaneously
In second inner chamber 192 at linkage end 33, now because the second magnetic valve 5 is still in power failure state, so the second intake adit
15th, the second linkage passage 162 is connected with pressed gas, due to the second of second piston 3 link end 33 face area less than the
The face area of two drive ends 31, therefore second piston 3 is still in the state for closing exhaust outlet 13；Further, since first piston 2
The first drive end 21 face area of the face area more than the first linkage end 23, therefore first piston 2 continues to move down to close
Main air outlet 12, so as to cut off main air inlet 11 toward the air feed of main air outlet 12, now at main air outlet 12 and pressurize passage 181
In packing state.
When to checking cylinder air draft, the first magnetic valve 4 and the second magnetic valve 5 all in electric state.Now, by the of first
Wing passage 171 is connected with the first intake adit 14, and to the air feed of the first drive end 21 of first piston 2, now first piston 2 exists
Move down to close main air outlet 12 in the presence of pressed gas；Meanwhile, the second piston 3 being connected with the first linkage passage 161
Second linkage end 33 at second inner chamber 192 in be connected with pressed gas.At second side passage 172 and the second intake adit 15
In the state of blocking, the pressed gas of the second linkage intake adit 15 of passage 162 and second are all by the exhaust outlet of the second magnetic valve 5
Emptying, and second piston 3 second linkage end 33 at second inner chamber 192 in pressed gas in the presence of, second piston 3
To open exhaust outlet 13, the pressed gas of main air outlet 12 are connected by pressurize passage 181, air draft ring groove 182, second for upper shifting
Groove 194 and the air draft of exhaust outlet 13.
Further, in the present invention, it is folded with elastic component between second drive end 31 and upper shell 17 of second piston 3
7.The elastic component 7 is spring, and it is used to close the provided auxiliary pressure of exhaust outlet 13 for second piston 3, further to help second
Piston 3 compresses exhaust outlet 13.
In the present invention, the adjustable contracting stifled 6 of internal diameter is detachably connected with respectively at main air inlet 11 and exhaust outlet 13.
The contracting stifled 6 can at any time be changed according to actual conditions, the air draft of its intake velocity and exhaust outlet 13 for being used to control main air inlet 11
Speed.
In an embodiment of the present invention, the cross section of main air inlet 11 supplies with the cross section of the first intake adit 14 or second
The ratio range of the cross section of wind passage 15 is 4~5, that is, the cross section of main air inlet 11 is the horizontal stroke of the first intake adit 14
4~5 times of the cross section of section or the second intake adit 15.The main air inlet 11 is primary path, and the pressed gas of its path are used
In the braking wind of vehicle, flow is big, therefore latus rectum design is larger, and the first intake adit 14 or the second intake adit 15 are control
Path processed, the pressed gas of its path are only used for driving the motion of first piston 2 or second piston 3, belong to imperial control pressure, flow
Amount require it is small, therefore latus rectum design it is smaller；This design of the invention meets the requirement of air purposes.
Several embodiments of the present invention are the foregoing is only, those skilled in the art is according to application documents disclosure
Various changes or modification can be carried out to the embodiment of the present invention without departing from the spirit and scope of the present invention.
