61, this push rod 61 matches through described cartridge cover 21 with steel ball 3.
In embodiment, valve body 1 being additionally provided with T mouth 13, this T mouth 13 communicates with the inner chamber of described valve body 1.The work of T mouth 13
With being that the residue oil pressure by spool 2 releases, it is to avoid the impact that electromagnetic valve is caused by remaining oil pressure, beneficially electromagnetic valve use the longevity
The raising of life.
In embodiment, the front side of coil block 4 is provided with front shroud 41, and the rear side of coil block 4 is provided with back shroud 42.
In embodiment, being provided with elastic washer 8 between back shroud 42 and described coil block 4, elastic washer 8 includes packing ring
Body 81 and the flexure strip 82 of washer body 81 projection.
Flexure strip 82 has 3 groups, often group 2, and 3 groups of flexure strips 82 are uniformly distributed in the periphery of washer body 81.During assembling,
Back shroud 42 is inwardly compressed, thus the flexure strip 82 on elastic washer 8 is flattened, owing to the elastic force of flexure strip 82 self can be
Back shroud 42 produces an outside thrust, and this thrust is causing prestressing force at back shroud 42, thus prevents the pine of back shroud 42
Dynamic, and then ensure that the stability that whole electromagnetic valve assembles, be so conducive to the stable operation of electromagnetic valve.
In embodiment, the stroke of dynamic iron core 6 is 0.5mm-1mm.
In embodiment, being provided with spring base 51 in static iron core 5, one end of spring 7 offsets with described spring base 51, its another
The inwall with described dynamic iron core 6 is held to offset.
In embodiment, electromagnet assembly and described valve body 1 are outside equipped with shell 14.Shell 14 is wrapped in valve body 1 and electricity
The periphery of the coil block 4 of magnet assemblies, thus electromagnet assembly and valve body 1 are fixed into an entirety.
In embodiment, between valve body 1 and spool 2, it is provided with sealing ring 15.The setting of sealing ring 15 ensure that valve body 1 and valve
Sealing between core 2, it is to avoid gap location generation seepage between valve body 1 and spool 2.
In embodiment, the overall structure that spool 2 is made for punching press, the overall structure that cartridge cover 21 is also made for punching press.Valve
Core 2 and cartridge cover 21 all use stamping parts, easy to process, and the concordance of product is good.
In embodiment, the end of the oil-in 2a of spool 2 is arc structure.
Operation principle:
This automatic gear-box gear control switch electromagnetic valve, including valve body 1, spool 2 and electromagnet assembly, spool 2 is assemblied in
In valve body 1, valve body 1 offers P mouth 11 and A mouth 12, and P mouth 11 communicates with described A mouth 12 through the inner chamber of spool 2, at valve in spool 2
It is provided with steel ball 3 between core 2 and cartridge cover 21, is matched with the oil-in 2a of spool 2 control P mouth 11 and A mouth 12 by steel ball 3
Between break-make, thus control the keying of electromagnetic valve.A centrally disposed push rod 61 of dynamic iron core 6, dynamic iron core 6 is at spring 7
The effect of elastic force, and make steel ball 3 match with the oil-in 2a of spool 2 by push rod 61.
When the coil block 4 of electromagnet assembly is not powered on, dynamic iron core 6 is pushed away by the elastic force of spring 7 to the left, then by dynamic ferrum
Steel ball 3 is pushed up by the push rod 61 at core 6 center to the left, makes steel ball 3 form sealing with the oil-in 2a of spool 2, thus by P mouth 11 and A
Cutting off between mouth 12, at this moment electromagnetic valve is just closed.
After the coil block 4 of electromagnet assembly is energized, coil block 4 produces electromagnetic force, makes iron core 6 overcome spring 7
Elastic force move right, the drive push rod 61 that moves to right of dynamic iron core 6 moves to right, and makes push rod 61 depart from steel ball 3；Steel ball 3 is losing top
After the active force of bar 61, being washed open by the oil pressure of P mouth 11, and then depart from oil-in 2a, seal by broken ring, P mouth 11 and A mouth 12 is led
Logical, at this moment electromagnetic valve is just in opening.
When, after power-off, dynamic iron core 6 loses the effect of electromagnetic force, moves to left the most again, finally make under the elastic force effect of spring 7
Steel ball 3 forms sealing, closed electromagnetic valve again with the oil-in 2a of spool 2；In spool 2, remaining oil pressure is then from T mouth 13 row
Go out.
Owing to steel ball 3 can only move between spool 2 and cartridge cover 21, therefore 6 need of the dynamic iron core of this electromagnetic valve are extremely short
Stroke just can realize to electromagnetic valve open and close control, make this electromagnetic valve control sensitive, fast response time.
Highly preferred embodiment of the present invention illustrates, those of ordinary skill in the art the various changes made or remodeling are the most not
Can depart from the scope of the present invention.
