Abstract
The utility model relates to an expansion valve, which comprises a valve body and an upper cover arranged on the valve body and is characterized in that tooth veins connected with the upper cover are arranged on the valve body. The upper cover is provided with a protruded connection portion connected with the valve body, threads matched with the tooth veins are arranged in the protruded connection portion, the upper cover is installed on the valve body through the tooth veins and the protruded connection portion, and super glue is further coated on the tooth veins for connecting the upper cover and the valve body. The upper cover and the valve body are connected through the tooth veins and bonded through the super glue, thereby improving the stability of connection between the upper cover and the valve body, simultaneously avoiding the complex operation technology in the prior art and avoiding pollution to the environment caused by pickling. The expansion valve has the advantages of being simple in operation, stable in structure, long in service life and the like, improves production efficiency of enterprises and is worth of promoting and using.
Description
Technical field
The utility model relates to a kind of valve mechanism, what be specifically related to is a kind of expansion valve.
Background technology
Expansion valve is a vitals in the refrigeration system, generally is installed between liquid storage cylinder and the evaporimeter.The liquid refrigerant of warm high pressure became the moist steam of low-temp low-pressure during expansion valve made through its throttling; Cold-producing medium absorbs heat and reaches refrigeration in evaporimeter then; Expansion valve changes through the terminal degree of superheat of evaporimeter and comes the by-pass valve control flow, prevents the under-utilized and engine knock phenomenon of evaporator area.
And existing expansion valve comprises valve body, welds circle, loam cake, and this loam cake links together with valve body through welding circle and scaling powder process high-temperature soldering at valve body; Carry out surface acid then and handle, remove a plurality of operating procedures such as the dirty part of surperficial grease and stolen goods again, its complex process; Production efficiency is low, and cost is high, because loam cake and valve body are Welding Structure; It is easy to generate the phenomenon of failure welding; Cause the expanding damage of valve body, and through the pickling operation, its acid solution causes environmental pollution.
The utility model content
To the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of technology simple, easy to make, and constitutionally stable expansion valve has improved the production efficiency of enterprise, has avoided failure welding or pickling partly to cause environmental pollution.
To achieve these goals, the utility model is to realize through following technical scheme:
A kind of expansion valve comprises valve body and the loam cake on the valve body is set, and it is characterized in that; The tooth line that connects loam cake is arranged on the said valve body; Cover on said and be provided with the protrusion connecting portion that connects valve body, in the protrusion connecting portion, be provided with the screw thread adaptive with the tooth line, said loam cake is installed on the valve body through tooth line and protrusion connecting portion; On the tooth line that said loam cake is connected with valve body, also scribble strong rubber, increase the steadiness that loam cake is connected with valve body.
According to above-mentioned expansion valve, wherein, what described strong rubber adopted is the superpower glue in epoxide alloy, has avoided coming off of loam cake.
The utility model adopts the tooth line to be connected loam cake and valve body, and bonding through strong rubber, has increased loam cake and valve body connection stability; Simultaneously, avoid the complex operations technology on the prior art, avoid the pollution of pickling environment; It has simple to operate, Stability Analysis of Structures, and cost is low; Advantages such as long service life have improved the production efficiency of enterprise, are worth of widely use.
Description of drawings
Specify the utility model below in conjunction with the accompanying drawing and the specific embodiment;
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the valve body structure sketch map of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2; A kind of easy to connect, stable, the simple a kind of expansion valve of production technology that the utility model provides; It comprises valve body 10 and loam cake 22, and valve body 10 is provided with two screwed links 11, and on valve body 10, also is provided with the tooth line 12 that connects loam cake; Through tooth line 12 loam cake 22 is installed on the valve body 10, makes its stable installation.
On loam cake 22 and tooth line 12 that valve body 10 is connected, also scribble strong rubber, increase the steadiness that loam cake is connected with valve body.
In the present embodiment, loam cake 22 is circular, is provided with the protrusion connecting portion 21 that connects valve body therebetween, in protrusion connecting portion 21, is provided with the screw thread adaptive with tooth line 12.
In the present embodiment, what strong rubber adopted is the superpower glue in epoxide alloy, has avoided coming off of loam cake.
The utility model adopts tooth line 12 to be connected with valve body 10 loam cake 22, and bonding through strong rubber, avoids the complex operations technology on the prior art; Increased loam cake 22 and valve body 10 connection stability, simultaneously, avoided the pollution of pickling environment; It has simple to operate; Stability Analysis of Structures, the advantage of long service life is worth of widely use.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to define
by appending claims and equivalent thereof.
Claims (2)
1. expansion valve; Comprise valve body and the loam cake on the valve body be set, it is characterized in that the tooth line that connects loam cake is arranged on the said valve body; Cover on said and be provided with the protrusion connecting portion that connects valve body; In the protrusion connecting portion, be provided with the screw thread adaptive with the tooth line, said loam cake is installed on the valve body through tooth line and protrusion connecting portion, on the tooth line that said loam cake is connected with valve body, also scribbles strong rubber.
