Description
Technical field
The present invention relates to the technical fields of the manufacture of low-voltage direct solenoid valve product, dynamic and static more particularly to a kind of change
The solenoid valve of core structure.
Background technique
Carburetor electromagnetic valve is the executive component of electronic control system, and main playing switching on-off action, solenoid valve is opened
Close characteristic reliability, directly affect whether carburetor works normally, as execute solenoid valve acting characteristic dynamic and static iron core,
The design of its structure is particularly critical.
In the prior art, it when dynamic and static iron core magnetic attraction and after solenoid valve power-off, due to the factor of remanent magnetism, will lead to
Dynamic iron core cannot overcome return spring force to cause dynamic iron core that cannot discharge, and lead to that solenoid valve failure phenomenon occurs.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of solenoid valves for changing dynamic and static core structure, in dynamic iron core
Actuation face be embedded in one every magnetic copper plug, after ensuring that dynamic iron core and static iron core are attracted, have fixation thick every magnetic between the two
Degree, it is ensured that after solenoid valve power-off, dynamic iron core quick release avoids dynamic iron core and possibility that static iron core directly contacts, that is, eliminates
Bad phenomenon is discharged caused by remanent magnetism, is reduced the ratio of rejected product in manufacturing process, is improved the reliability of product.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: provide a kind of dynamic and static iron core of change
The solenoid valve of structure, including solenoid valve body, dynamic iron core, static iron core and every magnetic copper plug, the dynamic iron core, static iron core and every
Magnetic copper plug is vertically provided at the middle position inside solenoid valve body, and the actuation face of the dynamic iron core bottom uses inner conical surface
Shrinkage pool structure, the bottom for being riveted on dynamic iron core in the form of interference fit every magnetic copper plug, the static iron core top
Actuation face use male cone (strobilus masculinus) post shapes corresponding with inner conical surface shrinkage pool structure.
In a preferred embodiment of the present invention, the bottom of the dynamic iron core is additionally provided with centre bore, described every magnetic
Copper plug is riveted together by way of centre bore uses interference fit with dynamic iron core.
In a preferred embodiment of the present invention, the dynamic iron core is consistent with the static iron core actuation frustoconical bevel angle in face.
In a preferred embodiment of the present invention, there are gaps between the dynamic iron core and static iron core.
The beneficial effects of the present invention are: the solenoid valve of the dynamic and static core structure of change of the invention, in the actuation face of dynamic iron core
Insertion one has a fixation every magnetic thickness, it is ensured that electricity between the two every magnetic copper plug after ensuring that dynamic iron core and static iron core are attracted
After magnet valve power-off, dynamic iron core quick release avoids dynamic iron core and possibility that static iron core directly contacts, that is, eliminates remanent magnetism and cause
Release bad phenomenon, reduce the ratio of rejected product in manufacturing process, improve the reliability of product.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, in which:
Fig. 1 is the structural schematic diagram of a preferred embodiment of the solenoid valve that the present invention changes dynamic and static core structure；
The label in accompanying drawing is: 1, solenoid valve body, 2, dynamic iron core, 3, static iron core, 4, every magnetic copper plug.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
As shown in Figure 1, the embodiment of the present invention includes:
A kind of solenoid valve changing dynamic and static core structure, including solenoid valve body 1, dynamic iron core 2, static iron core 3 and every magnetic copper plug
4, the dynamic iron core 2, static iron core 3 and it is vertically provided at the middle position inside solenoid valve body 1 every magnetic copper plug 4, it is described
2 bottom of dynamic iron core actuation face use inner conical surface shrinkage pool structure, it is described every magnetic copper plug 4 using interference fit in the form of riveting
In the bottom of dynamic iron core 2, the actuation face on 3 top of static iron core uses male cone (strobilus masculinus) column corresponding with inner conical surface shrinkage pool structure
Shape.
Among the above, the bottom of the dynamic iron core 2 is additionally provided with centre bore 21, described to pass through centre bore every magnetic copper plug 4
21 are riveted together in the form of interference fit with dynamic iron core 2.
Wherein, the dynamic iron core 2 is consistent with the actuation frustoconical bevel angle in face of static iron core 3.Dynamic iron core 2 and static iron core 3 are attracted
Afterwards, it due to the presence every magnetic copper plug 4, with the presence of certain gap between interior male cone (strobilus masculinus), avoids dynamic iron core 2 and static iron core is direct
The possibility of contact eliminates and discharges bad phenomenon caused by remanent magnetism.
In conclusion the solenoid valve of the dynamic and static core structure of change of the invention, the actuation face of dynamic iron core be embedded in one every
Magnetic copper plug has a fixation every magnetic thickness between the two after ensuring that dynamic iron core and static iron core are attracted, it is ensured that solenoid valve power-off
Afterwards, dynamic iron core quick release avoids dynamic iron core and possibility that static iron core directly contacts, that is, eliminates release caused by remanent magnetism not
Good phenomenon reduces the ratio of rejected product in manufacturing process, improves the reliability of product.
