Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As shown in Figure 1-2, magnetic shield of the present utility model is made by nonmagnetic substance, including elastic flange 41, the
One shoulder hole 42, shoulder 43 and the second shoulder hole 44；Wherein, the aperture of described first shoulder hole 42 is more than the second shoulder hole 44
Aperture；One end of described second shoulder hole 44 is cecum, and the other end is held in the mouth mutually by the top of shoulder 43 with the first shoulder hole 42
Connect, form cup-like structure；On the circumferential edges of the first shoulder hole 42 bottom, compartment of terrain stretches out and is provided with elastic flange 41.
It is to say, the top half of this utility model magnetic shield uses the structure of cup-shaped, bottom uses elastic flange mode, magnetic shield
Using radial seal mode to seal with the valve seat of electromagnetic valve, the elastic flange of magnetic shield plays during electromagnetic valve assembles
Foozle compensate and use during the effect of each parts thermal distortion compensation, meet simultaneously electromagnetic valve to magnetic shield every
Magnetic, guide, the fixing function demand with black box.
Wherein, as in figure 2 it is shown, above-mentioned elastic flange 41 is to be made by elastomeric material, form elastomer 415；As
Shown in Fig. 3, above-mentioned elastic flange 41 includes flange part 411, conical surface portion 412 and shoulders 413；First shoulder hole 42 bottom
Edge be connected with shoulders 413 phase in the way of arc-shaped transition, conical surface portion 412 is connected mutually with the bottom of shoulders 413 end,
End in conical surface portion 412 is extended flange part 411.Shown in Fig. 5 described as follows, under the effect of flange part 411, it is energy
Enough guarantee is fully contacted with magnetic conductance seat flange 74, forms stable contact surface；Under the effect in conical surface portion 412, it is ensured that elastomer
The deformation direction of 415 is to fix laterally, i.e. diameter augment direction, and is easy to manufacture realization (demoulding)；And shoulders 413
Then it is to increase the radial rigidity of the first shoulder hole 42, when magnetic shield is by axial force, and when elastomer 415 is deformed, it is right to reduce
The radial deformation impact of the first shoulder hole 42.
As Figure 2-3, in the cecum of above-mentioned second shoulder hole 44, spherical boss 45 is distributed, this spherical boss 45 court
In the second shoulder hole 44 hole.It is to say, the top of this utility model magnetic shield is inwardly formed a hemisphere jut, as
This, can reduce the armature of electromagnetic valve and the making contact area of magnetic shield so that resistance during armature disengagement spacer is less, Du
Absolutely armature edge produces the problem of flange, so that armature will not be stuck in flux sleeve, to ensure electromagnetism because of collision
Valve can the most normally use.
Wherein, the circumferential edges of the first above-mentioned shoulder hole 42 bottom stretches out evenly and at intervals it is provided with three
Individual, four or six elastic flange 41.Breach 414 is formed between elastic flange and elastic flange.Due to elastic flange 41
Number is that during affecting this magnetic shield compensation foozle played in electromagnetic valve assembling process and using, each parts are warm
One of key factor of deformation-compensated effect, if being provided with 2 or the elastic flange of odd number (except 3), can be due to system
Make error and cause the discontinuity of each elastic flange, thus the axle making a concerted effort to deviate magnetic shield 4 of elastic force after causing deformation
Line；If the number of elastic flange 41 arranges too much, then can increase manufacturing cost, reduce the reliability of part.
During as it is shown in figure 5, this utility model is arranged on electromagnetic valve use, owing to being provided with on the coil block 2 of electromagnetic valve
Flux sleeve 3, flux sleeve 3 is axially positioned by the shoulder 43 of magnetic shield 4 by its lower surface, and by the second-order of magnetic shield 4
The outer surface in ladder hole 44 carries out radially positioning；Magnetic shield 4 carries out footpath by the outer surface of its second shoulder hole 44 and shell 1 inwall
To location；Armature 5 and magnetic conductance seat 7 are installed in magnetic shield 4 successively, and armature 5 passes through its outer surface by the second ladder of magnetic shield 4
The inner surface in hole 44 carries out radially positioning；Equipped with the first sealing ring 8 in annular groove 73 on magnetic conductance seat boss 71, and every magnetic
The inner surface of the first shoulder hole 42 of set 4 is formed and seals；The elastic flange 41 of magnetic shield 4 is fixed on magnetic conductance seat flange 74 upper end
Face, forms axially location to magnetic shield 4.It is to say, other main parts in this utility model solenoid valve casing 1
Guide, location mainly by with the cooperating installation of magnetic shield 4 and realize, completely without by welding, screw thread even
The extraneous guide-localization mode such as connect, therefore can efficiently and rapidly complete the assembling of each parts of electromagnetic valve, and assemble ground
Effective, such that it is able to extend the Acceptable life of electromagnetic valve.
Meanwhile, during the assembling of electromagnetic valve each parts and using, elastic flange 41 can be by radial force
In the case of form certain elastic deformation, can be to the electromagnetism caused due to assembling, foozle and environment, temperature change
Valve inner body plays the effect of compensation due to material is different, thermal coefficient of expansion difference causes thermal deformation, such that it is able to effectively
Ground solves existing electromagnetic valve seal failure and the technical problem of sealing member reliability decrease.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim
Within the scope of.
