The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Refering to fig. 1 shown in -3, air suspension valve of the invention, including valve body 1 and the valve chamber 2 being arranged inside valve body 1, valve
Body 1 and valve chamber 2 are integrally formed, and using the techniques one-pass molding such as die casting, injection molding, high precision machining, period are short, raw suitable for high-volume
Production；Switch valve 3, the first Air inflating and exhausting valve 4 and the second Air inflating and exhausting valve 5 are also respectively provided in valve body 1, switch valve 3, first fill exhaust
Valve 4 and the second Air inflating and exhausting valve 5 divide valve chamber 2 for the first valve chamber 21, the second valve chamber 22, third valve chamber 23, the 4th valve chamber 24 and
Five valve chambers 25,1 outside of valve body also offer air inlet 6, exhaust outlet 7, the first working hole 8 and the second working hole 9, air inlet respectively
6 are connected by first flow 11 with the 5th valve chamber 25, and the 5th valve chamber 25 is connected by switch valve 3 with the second valve chamber 22, the
Two valve chambers 22 are connected with third valve chamber 23, the 4th valve chamber 24 respectively by third flow channel 12, and third valve chamber 23 is filled by first
Air bleeding valve 4 is connected with the first working hole 8, and the 4th valve chamber 24 is connected by the second Air inflating and exhausting valve 5 with the second working hole 9, the
One working hole 8 and the second working hole 9 are connected with load respectively, the second valve chamber 22 by switch valve 2 also with 21 phase of the first valve chamber
Connection, the first valve chamber 21 are connected with exhaust outlet 7.
Specifically, 3 structure of switch valve is similar to two-bit triplet solenoid valve, 5 structure of the first Air inflating and exhausting valve 4 and the second Air inflating and exhausting valve
It is identical, it is similar with 2/2-way solenoid valve, respectively include coil 31, dynamic iron core component 32, plunger shaft 33, blocking valve port
34, piston rod 35 and resetting spring 36, coil 31 are connect with 32 magnetism of dynamic iron core group, and dynamic iron core component 32 is arranged in plunger shaft 33
Air inlet port, piston rod 35 are slidably arranged in inside plunger shaft 33, and 35 one end of piston rod and blocking valve port 34 are close in static state
Envelope connection, resetting spring 36 are arranged between piston rod 35 and blocking valve port 34, and blocking valve port 34 is sealingly disposed in plunger shaft
33 air outlets.
In the present invention, compressed air enters valve body 1 from air inlet 6, and enters the 5th valve chamber 25 by first flow 11, this
When due to 3 coil of switch valve, 31 dead electricity, blocking valve port 34 is in static sealing with piston rod 35, and compressed air medium cannot be introduced into
Second valve chamber 22；When 3 coil 31 of switch valve must be electric, dynamic iron core component 32 is attracted by coil 31, dynamic iron core component 32 and work
The valve port for filling in 33 air inlet port of chamber is opened, and the air dielectric of certain pressure enters 33 compression piston bar 35 of plunger shaft, overcomes reset
The elastic force of spring 36 moves downward so that blocking valve port 34 is detached from piston rod 35, and air dielectric enters the second valve chamber 22, compression
Air enters third valve chamber 23 and the 4th valve chamber 24 simultaneously by third flow channel 12 again；When 4 coil of the first Air inflating and exhausting valve obtain it is electric
When, dynamic iron core component is attracted, and valve port is opened, and piston rod compression moves downward, and blocking valve port is opened, the pressure of third valve chamber 23
Stream of compressed air exits into left air bag through blocking valve port from the first working hole 8；Similarly, the coil in the second Air inflating and exhausting valve 5 obtains electric,
Second working hole 9 also has compressed air outflow to enter right air bag；If at this point, in the first Air inflating and exhausting valve 4 and the second Air inflating and exhausting valve 5
Coil losing electricity, the first working hole 8 and the second working hole 9 are flowed out without air, no longer give air bag load gas supply, and the mutual not shadow of the two
It rings, can individually supply；If the coil in the first Air inflating and exhausting valve 4 and the second Air inflating and exhausting valve 5 obtains electric, 3 coil 31 of switch valve mistake
Electricity, under the action of 36 power of resetting spring, piston rod 35 resets, and the static sealing again of blocking valve port 34, at this point, the second valve chamber
22 are connected with the first valve chamber 21, and the air in air bag load returns through the second valve chamber 22 from third flow channel 12 and enters the first valve
Chamber 21 is discharged into air from exhaust outlet 7.Whole process that is, 3 coils it is electric, the first working hole 8 and the second working hole 9 are
There is air stream to go out, gives left and right airbag aeration；The coil losing electricity of first Air inflating and exhausting valve 4 and the second Air inflating and exhausting valve 5 stops inflation；It opens
3 coil losing electricity of valve is closed, the first Air inflating and exhausting valve 4 and 5 coil of the second Air inflating and exhausting valve obtain electric, air bag deflation pressure release.
The present invention is integrally formed by valve body 1 and valve chamber 2, improves the machining accuracy of air suspension valve, shortens processing week
Phase, suitable for producing in enormous quantities；Using pilot-operated type structure height integrated switch valve 3, the first Air inflating and exhausting valve 4 and second on valve body 1
Air inflating and exhausting valve 5, realizing air suspension valve has multiple working holes, and spool quantity can meet various working there are two types of selection
Demand, reliable in action.Meanwhile overall appearance of the invention is compact, long lifespan, it is dust-proof excellent the advantages that.
Preferably, exhaust outlet 7 is also associated with muffler 14, helps to reduce noise pollution in exhaust process, improves air
Hang the environment protecting of valve.
Preferably, the outside of valve body 1 is further opened with third working hole 10 or multiple, and third working hole 10 passes through second
Runner 13 is connected with the second valve chamber 22, effectively improves the quantity of working hole, can meet various working demand.
