Wherein, cloud plate upper clipping claw quantity is three, so as not to block the wire connecting portion of driving coil.
Wherein, arc hole includes spherical concave surface and cylindrical tunnel.
Wherein, it is embedded with the first magnet below the cloud plate, in centre hole peripheral side.
Wherein, cake circle top surface is embedded with the second magnet in place above arc hole.
Beneficial effects of the present invention are：By the cooperation of cloud plate and cake circle, two major functions are realized, 1. extensions use the longevity
Life, due to the effect of compression spring so that main valve body has certain damping effect during vibrations, makes main valve body and coil
Between vibration influence greatly reduce, greatly add the service life of expansion valve.2. can easily it dismantle, it is only necessary to one
Individual toothpick, you can easily disassemble main valve body from cloud plate.

Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not the reality the present invention
Apply scope and be confined to this.
As shown in Figures 1 to 6, the expansion valve of a kind of removable convenient dismounting described in the present embodiment,
Include coiler part, the coiler part, which includes, is equidistantly provided with multiple claws on the cloud plate a1 of patty, cloud plate a1
A3, driving coil a2 are fastened on cloud plate a1 top surfaces by claw a3, and Yun Ban a1 centers, which are provided with, to be used to make main valve body pass through cloud plate a1
Driving coil a2 centre hole a9 is reached, cloud plate a1 bottom surfaces are provided with four overhead-valves of the setting that is symmetrically centrosymmetric, each overhead-valve
Include an accommodating chamber a4, accommodating chamber a4 towards cloud plate a1 centers side be to accommodating chamber a4 warp-wises at opening, opening
Extend confining a5, also include the bullet a8 of cylinder at accommodating chamber a4 openings, bullet a8 one end is hemispherical,
The other end is connected with accommodating chamber a4 bottoms by compression spring；Lateral projections of the bullet a8 close to compression spring one end have and confining
The corresponding snap arm a6 of a5；
Also include main valve body portion, the main valve body includes main valve body fixed part b1, pipeline b4, induction part, also included
The cake circle b2 on main valve phosphor bodies fixed part is set in, cake circle b2 includes for being arranged punching for main valve phosphor bodies fixed part,
Cake circle b2 peripheries are towards center provided with four arc hole b5；It is placed equidistant between four arc hole b5.
The expansion valve when in use, by main valve body portion after the centre hole a9 of cloud plate a1 bottoms is filled in, by cylinder
Bullet a8 one end of shape is embedded in the b5 of arc hole, just completes assembling.Because bullet a8 card is provided as using so that main valve body is protected
Hold in the fixed position.When vibrations when, due to compression spring, can effectively filter vibrations, in addition, bullet a8 snap arm a6 with
Confining a5, which is served, prevents the problem of bullet a8 is run out of outside accommodating chamber a4 completely.
In the present embodiment, cloud plate a1 upper clipping claw a3 quantity is three, so as not to block driving coil a2 wire connecting portion a10.
Wire connecting portion a10 is risen into position, the coil of most of models can be replaced.
In the present embodiment, arc hole b5 includes spherical concave surface and cylindrical tunnel.So add arc hole b5's
Depth, can effectively prevent running out of for bullet a8.
In the present embodiment, the first magnet a7 is embedded with below the cloud plate a1, in centre hole a9 peripheral sides.Wherein, cake circle
B2 top surfaces are embedded with the second magnet b3 in place above the b5 of arc hole.Two magnet correspondences, it is attracting, it is effectively increased the cake circle of valve body
Fixing power between b2 and cloud plate a1, further prevents main valve body from coming off.
By cloud plate a1 and cake circle b2 cooperation, two major functions, 1. extension service lifes, due to compression spring are realized
Effect so that main valve body has certain damping effect during vibrations, makes the vibration influence between main valve body and coil
Greatly reduce, greatly add the service life of expansion valve.2. can easily it dismantle, it is only necessary to a toothpick, you can side
Main valve body being disassembled from cloud plate a1 just.
Wherein, applicant is before the product is designed, and by repeatedly studying discovery, expansion valve is when vibrations, main valve
The radial direction vibrations number of times of body is much larger than axial vibrations number of times and amplitude.Therefore, the thing followed be exactly transverse vibration frequency and
Amplitude is larger to cause connection between main valve body and coil to loosen until coming off.Therefore solving this problem needs to keep away transverse vibration
Exempt from the principal direction as design.
Described above is only the preferred embodiment of the present invention, therefore all structures according to described in present patent application scope
Make, the equivalent change or modification that feature and principle are done, in the protection domain of present patent application.
