Abstract
The invention discloses an automotive air conditioning copper expansion valve comprising a valve body. An inlet and an outlet are arranged on the valve body. The automotive air conditioning copper expansion valve is characterized in that clamping grooves are reserved on the inlet which is further provided with a filter screen, the filter screen comprises a filter screen body, filtering pores are reserved on the filter screen body, and convex fasteners which are fastened with the clamping grooves in an embedded manner are arranged on the filter screen body. The automotive air conditioning copper expansion valve has the advantages that by the aid of the filter screen, impurities can be effectively prevented from interfering normal working of the automotive air conditioning copper expansion valve, and the automotive air conditioning copper expansion valve is convenient to clean and maintain, and long in service life.
Description
Technical field
The present invention relates to a kind of air conditioning for automobiles copper expansion valve, be specifically related to a kind of air conditioning for automobiles copper expansion valve that can impurity screening.
Background technology
All comprise import and outlet in the existing air conditioning for automobiles copper expansion valve, liquid flows out from outlet through import.After long-term the use, can carry various impurity usually in the liquid of the import of flowing through.These impurity tend to disturb the operate as normal of air conditioning for automobiles copper expansion valve after entering import, can shorten the service life of air conditioning for automobiles copper expansion valve usually.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of air conditioning for automobiles copper expansion valve.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Air conditioning for automobiles copper expansion valve, comprise valve body, described valve body is provided with import and outlet, it is characterized in that, offer draw-in groove in the described import, described import also is provided with screen pack, and described screen pack comprises the screen pack body, offer filter bores on the screen pack body, described screen pack body is provided with the convex buckle with described draw-in groove tabling.
Aforesaid air conditioning for automobiles copper expansion valve is characterized in that, described draw-in groove at least one.
Aforesaid air conditioning for automobiles copper expansion valve is characterized in that described draw-in groove is square draw-in groove.
Aforesaid air conditioning for automobiles copper expansion valve is characterized in that the aperture of described filter bores is 1-2mm.
Aforesaid air conditioning for automobiles copper expansion valve is characterized in that the tail end of described screen pack body is connected with extrusion.
Usefulness of the present invention is: air conditioning for automobiles copper expansion valve of the present invention can avoid impurity to disturb the operate as normal of air conditioning for automobiles copper expansion valve by screen pack is set effectively, and air conditioning for automobiles copper expansion valve of the present invention is convenient to cleaning maintenance, long service life.
Description of drawings
Fig. 1 is a preferred structural representation of implementing of the present invention.
The implication of Reference numeral among the figure:
1, outlet, 2, import, 3, draw-in groove, 4, the screen pack body, 5, the convex buckle, 6, filter bores, 7, extrusion.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to shown in Figure 1, air conditioning for automobiles copper expansion valve of the present invention, comprise valve body, valve body is provided with import 2 and outlet 1, it is characterized in that, offers draw-in groove 3 in the import 2, import 2 also is provided with screen pack, screen pack comprises screen pack body 4, offers filter bores 6 on the screen pack body 4, and screen pack body 4 is provided with the convex buckle 5 with draw-in groove 3 tablings.Screen pack of the present invention can adopt the material with certain elastic-restoring force to make, and can be made by metallic copper such as it.When actual motion, the body of screen pack can be filled in the import 2 of valve body, and be made convex buckle 5 and draw-in groove 3 chimeric mutually, under the elastic-restoring force effect of screen pack self, can guarantee that screen pack and import 2 keep fixing position.
The present invention does not limit the quantity of draw-in groove 3, and it is at least one, if be more than two, convex buckle 5 also will be arranged to position and the quantity corresponding with draw-in groove 3.In the reality, the preferred draw-in groove 3 of the present invention is square draw-in groove 3, fixed effect the best like this.
Further, the aperture in limiting filter of the present invention hole 6 is 1-2mm.This can and not hinder actual proof flow through two requirements of screen pack of liquid at effective impurity screening and reach balance.
Further, the tail end at screen pack body 4 is connected with extrusion 7.After adopting extrusion 7, can when extruding extrusion 7, the body of screen pack be filled in the import 2 of valve body, unclamp extrusion 7 then.If desire is taken out screen pack and cleaned, only need push extrusion 7 again and take out screen pack.
Air conditioning for automobiles copper expansion valve of the present invention can avoid impurity to disturb the operate as normal of air conditioning for automobiles copper expansion valve by screen pack is set effectively, and air conditioning for automobiles copper expansion valve of the present invention is convenient to cleaning maintenance, long service life.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
