Centre hole, cloud board bottom face are equipped with four overhead-valves of the setting that is symmetrically centrosymmetric, and each overhead-valve includes an accommodating chamber, accommodate
Chamber is opening towards cloud plate center side, and it further includes having positioned at accommodating chamber that opening, which radially extends out confining to accommodating chamber,
Opening, cylindrical bullet, bullet one end are hemispherical, and the other end is connect with accommodating chamber bottom by compressed spring；Bullet
The lateral projections of the nearly compressed spring one end of head rest have snap arm corresponding with confining；
It further include having main valve body portion, it further includes having that the main valve body, which includes main valve body fixed part, pipeline, induction part,
The cake circle being set on main valve body fixed part, cake circle include for being arranged punching for main valve body fixed part, cake circle periphery towards
Center set there are four arc cheat；It is placed equidistant between four arc holes.
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, the first magnet is embedded with below the cloud plate, in centre hole peripheral side.
Wherein, cake circle top surface is embedded with the second magnet above arc hole.
The invention has the benefit that passing through the cooperation of cloud plate and cake circle, two major functions are realized, 1. extensions use the longevity
Life, since the effect of compressed spring makes main valve body and coil so that main valve body has certain damping effect during vibration
Between vibration influence greatly reduce, greatly increase the service life of expansion valve.2. the disassembly that can be convenient, it is only necessary to one
A toothpick can easily disassemble main valve body from cloud plate.

Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments, is not reality of the invention
It applies range and is confined to this.
As shown in Figures 1 to 6, the removable expansion valve easy to disassemble of one kind described in the present embodiment,
It include coiler part, the coiler part includes the cloud plate a1 of patty, is equidistantly equipped on cloud plate a1 multiple
Claw a3, driving coil a2 are fastened on the top surface cloud plate a1 by claw a3, and the cloud center plate a1 is equipped with for making main valve body pass through cloud
Plate a1 reaches the centre hole a9 of driving coil a2, and the cloud bottom surface plate a1 is equipped with four overhead-valves of the setting that is symmetrically centrosymmetric, each
Overhead-valve includes an accommodating chamber a4, and accommodating chamber a4 is opening towards the cloud center plate a1 side, and opening is to accommodating chamber a4
Confining a5 is radially extended out, further includes having positioned at accommodating chamber a4 opening, cylindrical bullet a8, the one end bullet a8 is hemisphere
Shape, the other end are connect with the bottom accommodating chamber a4 by compressed spring；Lateral projections of the bullet a8 close to compressed spring one end have with
The corresponding snap arm a6 of confining a5；
It further include having main valve body portion, the main valve body includes main valve body fixed part b1, pipeline b4, induction part, is also wrapped
The cake circle b2 being set on main valve body fixed part is included, cake circle b2 includes for being arranged punching for main valve body fixed part, cake circle
The periphery b2 towards center set there are four arc cheat b5；It is placed equidistant between four arc hole b5.
The expansion valve when in use, after main valve body portion is filled in from the centre hole a9 of the bottom cloud plate a1, by cylinder
One end bullet a8 of shape is embedded in the b5 of arc hole, just completes assembling.Since the card of bullet a8 is provided as using, so that main valve body is protected
It holds in the fixation position.When vibration when, due to compressed spring, can effectively filter vibration, in addition, the snap arm a6 of bullet a8 with
Confining a5 plays the problem for preventing bullet a8 from 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 the wire connecting portion a10 of driving coil a2.
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.Increase arc hole b5's in this way
Running out of for bullet a8 can be effectively prevented in depth.
In the present embodiment, the first magnet a7 is embedded with below the cloud plate a1, in centre hole a9 peripheral side.Wherein, cake circle
The top surface b2 is embedded with the second magnet b3 above the b5 of arc hole.Two magnet are corresponding, attracting, effectively increase the cake circle of valve body
Fixing power between b2 and cloud plate a1, further prevents main valve body to fall off.
By the cooperation of cloud plate a1 and cake circle b2, two major functions are realized, 1. extend service life, due to compressed spring
Effect make the vibration influence between main valve body and coil so that main valve body has certain damping effect during vibration
It greatly reduces, greatly increases the service life of expansion valve.2. the disassembly that can be convenient, it is only necessary to a toothpick, Ji Kefang
Main valve body being disassembled from cloud plate a1 just.
Wherein, applicant is before designing the product, by multiple the study found that expansion valve is when vibration, main valve
The radial vibration number of body is much larger than axial vibrations number and amplitude.Therefore, it is followed by that the frequency of transverse vibration and
Amplitude is larger to cause connection between main valve body and coil to loosen until falling off.Therefore this problem is solved to need to keep away transverse vibration
Exempt from the principal direction as design.
The above is only a preferred embodiment of the invention, therefore all according to structure described in present patent application range
It makes, the equivalent change or modification that feature and principle are done, in the protection scope of present patent application.
