Description
Technical field
The present invention relates to a kind of novel electronic expansion valve coil locating structure.
Background technology
In prior art, coil is fixed on valve body commonly used auxiliary component, and common mode is in coil component
Upper setting locator card, arranges frame/piece on valve body, by the cooperation of locator card and locating rack/piece, coil component is fixed on valve
On body.For example in Publication No. " 102840372 ", the patent of invention of entitled " a kind of expansion valve and its coil ", disclose
State the location structure of coil component, and for example Publication No. " 101799087 ", entitled " coil connecting structure and electronic expansion
In the patent of invention of valve ", also disclose that the location structure of above-mentioned coil component.Disclosed in the former, electric expansion valve is in practical application
During cannot according to installation environment change coil component setting angle, although electric expansion valve disclosed in the latter can be polygonal
Degree is installed, but detent mechanism is complicated, and spacer needs to be welded on valve body, and locator card is connected to coil bottom, and spacer is again
Engage with the bending hook on locator card；Although it is complicated that this structural stability, has manufacturing process very well, coil component
The shortcomings of dismounting inconvenience.
In view of this, the present inventor proposes improvement with regard to this, there is provided a kind of novel electronic expansion valve coil locating structure, and one
The technical problems such as the coil locating structure that aspect solves existing electric expansion valve is complicated, dismounting inconvenience, on the other hand manufacture work
Skill simplifies, and cost reduces.
Content of the invention
The invention aims to offer is a kind of can solve the problem that the weak point and technology referring in above-mentioned background technology
The novel electronic expansion valve coil locating structure of problem.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of novel electronic expansion valve coil locating structure, including coil, described coil is arranged on the valve of described electric expansion valve
On body it is characterised in that：Form first annular spring groove, on the outer wall of described valve body on the bottom port inwall of described coil
It is provided with the second ring spring groove, also includes turn, described turn is located at described first annular spring groove and institute when mounted
State between the second ring spring groove；Form draw-in groove in described coil bottom port, described valve body is provided with location hole, in institute
State and in location hole, carry alignment pin.
The present invention is done and arranges further, described draw-in groove is multiple, and equidistantly distributed is on described coil bottom port.
The present invention is done and arranges further, the quantity of described draw-in groove is 4-20.
The present invention is done and arranges further, between adjacent draw-in groove, form the pillar of aciculiform shape.
The present invention is done and arranges further, the size of described first annular spring groove and described second ring spring groove
Equally.
Compared with the prior art, the present invention has following beneficial effect：
The present invention includes coil, and described coil is arranged on the valve body of described electric expansion valve, in the bottom port of described coil
First annular spring groove is formed on wall, the second ring spring groove is provided with the outer wall of described valve body, also includes turn；Institute
State coil bottom port and form draw-in groove, described valve body is provided with location hole, described location hole carries alignment pin.This
Bright realize interlocking by first annular spring groove and the second ring spring groove, and turn be located at first annular spring groove with described
Between second ring spring groove, realize realizing clamping between coil and valve body.The present invention is inserted into location hole also by alignment pin
In, and draw-in groove is buckled on alignment pin, realize coil and fix, and prevent coil from moving left and right.
During actual installation, first alignment pin is embedded location hole first, its embedded mode can be by the side of extruding
Formula inserts location hole alignment pin, plays preferable fixation.
Secondly, in order to implement dismantled and assembled convenience, the second ring spring groove is provided with valve body, then embeds turn, profit
The size be consistent with the elasticity of turn and with spring groove, is interlocked the first annular spring groove on coil with turn
Close.
Finally, in order to implement multi-angle install, be provided with draw-in groove in coil component, can with valve seat on alignment pin phase clamping,
With this simultaneously it is therefore prevented that electric expansion valve is in operation, coil moves left and right.
Generally, include at coil windings portion and wiring in coil, this enforcement adopts the grog outsourcing of integrated injection molding
Cover at wiring and coil windings portion, play more preferable waterproof and antisepsises, thus extend the use longevity of electric expansion valve
Life.
From the foregoing, it will be observed that the present invention can solve the problem that the shortcomings of the prior art, buckle is installed conveniently, can be polygonal
Degree is installed, and meets different requirements, applied range.
