Abstract
It is used the utility model discloses a kind of electric expansion valve and is based on asymmetrical guiding magnet rotor, including magnet rotor magnet, it is characterized by: the magnet rotor magnet is column circular ring structure, it is equipped on the inside of column annulus along axial raised guiding rib, insertion is connected with guiding steel disc at the top of column annulus one end, it is oriented to the bending that steel disc center is equipped with protrusion, bending is equipped with guiding circular hole.The utility model cooperates guiding two guide frames of steel disc to realize that the guide function of magnet rotor is accepted by guiding rib, simplifies the structure of magnet rotor indirectly, realizes the dual guidance capability of magnet rotor magnet.
Description
Technical field
The utility model relates to a kind of magnet, uses in particular to a kind of electric expansion valve based on magnetic turn of asymmetrical guiding
Son.
Background technique
For convertible frequency air-conditioner, it relies primarily on electric expansion valve and accurately controls cold medium flux, existing electric expansion valve at present
Its main operational principle is stator coil socket valve body, passes through the intracorporal magnet rotor rotation control of stator coil control valve
The aperture of spool reaches cold medium flux control.Its structure of the magnet of magnet rotor is such as China Patent No. at present
The magnetic rotor structure of the solenoid valve of CN02254673.1 is identical, and magnet rotor magnet acts only as providing magnet not
Other technologies effect is generated, also not to its improved any technical clarification, but its rotor structure is relative complex ability
The object of field technique personnel research is the technical pattern for how simplifying magnet rotor by the improvement of magnet rotor magnet.
Summary of the invention
The utility model provides that a kind of structure is simple, the electric expansion valve with guide function is with being based on asymmetrical lead
Magnetropism rotor.
A kind of electric expansion valve, which is used, is based on asymmetrical guiding magnet rotor, including magnet rotor magnet, the magnetism
Rotor magnet is column circular ring structure, is equipped on the inside of column annulus embedding at the top of axial raised guiding rib, column annulus one end
Enter to be connected with guiding steel disc, guiding steel disc center is equipped with the bending of protrusion, and bending is equipped with guiding circular hole；The guiding steel disc
Thickening at the top of wall ring and guiding rib on downside contact column annulus.This kind of magnet rotor magnet is led by guiding rib cooperation
It realizes that the guide function of magnet rotor is accepted to two guide frames of steel disc, simplifies the structure of magnet rotor indirectly, realize
The dual guidance capability of magnet rotor magnet.
The guiding rib cross section is triangle.The guiding rib cross section is trapezoidal.The guiding rib is transversal
Face is arc-shaped.The shape of guiding rib cross section is not limited to the shape that the utility model is pointed out and is also possible to other suitably
Structure.
The utility model cooperates guiding two guide frames of steel disc to realize that the guide function of magnet rotor is held by guiding rib
It connects, simplifies the structure of magnet rotor indirectly, realize the dual guidance capability of magnet rotor magnet.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view of the utility model electric expansion valve based on asymmetrical guiding magnet rotor；
Fig. 2 is present invention looks up structural representation of the utility model electric expansion valve based on asymmetrical guiding magnet rotor.
Specific embodiment
A kind of electric expansion valve, which is used, as shown in Figs. 1-2 is based on asymmetrical guiding magnet rotor, including magnet rotor magnet
5, magnet rotor magnet 5 is column circular ring structure, is equipped on the inside of column annulus along axial raised guiding rib 1, column annulus one
The insertion of end top is connected with guiding steel disc 2, and guiding 2 center of steel disc is equipped with the bending of protrusion, and bending is equipped with guiding circular hole 6 and reaches
The technical purpose of dual guiding.
Thickening on 2 downside of steel disc contact column annulus is preferably directed as structure to increase at the top of wall ring 3 and guiding rib 1
Add magnet rotor magnet for the support performance of guiding steel disc 2.
Being preferably directed muscle cross section as structure is that triangle is trapezoidal or arc-shaped.
