Embodiment
In order to make the object of outlet pipe of the present invention and forming method and compressor, technological scheme and advantage clearly understand, below in conjunction with concrete drawings and the specific embodiments, the present invention is further elaborated.
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Current outlet pipe is all made up of one whole copper pipe, and the increase of copper pipe length must bring the increase of cost.The price of copper pipe is general higher, and each compressor is provided with many outlet pipes, and it is more that such holistic cost increases.
In order to solve the problem that above-mentioned cost increases under the prerequisite ensureing exhaust pipe length, the present invention considers the body of outlet pipe can adopt different materials as required, can adopt in less demanding position the steel pipe etc. that price is lower, while reducing compressor oil absorbency, can not increase the cost of compressor like this.
See Fig. 1, outlet pipe of the present invention comprises the first body 100, second body 200 and retaining ring 300, wherein the first body 100 communicates with the second body 200, the outside of retaining ring 300 covered section first body 100 and part second body 200, and the first body 100 and the second body 200 are fixed by retaining ring 300.In the present embodiment, retaining ring 300 is coated on the outside of the first end 101 near the second body 200 of the first body 100 and second end 201 near the first body 100 of the second body 200.After it should be noted that the first body and the second body are fixed by retaining ring, first end 101 and the second end 201 can contact with each other, also can be separated from each other, can be connected both when first end 101 contacts with each other with the second end 201 and also can not connect, as long as the first body 100 can be realized and the second body 200 communicates.
Wherein the first body 100 is different with the material of the second body 200, and such first body 100 and the second body 200 just can select different materials as required, thus reduces the cost of whole outlet pipe under the prerequisite ensureing exhaust pipe length.
See Fig. 2 to Fig. 4, the first body 100 comprises main paragraph 120 and flared section 110, and wherein flared section 110 can be made by the processing mode of enlarging, and main paragraph 120 is near the second body, and first end 101 is positioned on main paragraph 120.See Fig. 5 to Fig. 7, the second body 200 is an overall straight tube.Retaining ring 300 is coated on the outer wall of portion body section 120 and part second body 200.
Preferably, as a kind of embodiment, in the present embodiment, the first body 100 is copper pipe or copper-plated tube, and the second body 200 is steel pipe.When outlet pipe is used for compressor, upper cover or the lower cover of the first body 100 and compressor are connected, in order to ensure welding performance, first body is set to copper pipe by the present embodiment, and the second body directly do not contacted with upper cover or lower cover is adopted steel pipe material, can reduce costs to a great extent like this.Wherein, the length of the first body is less than the length of the second body.
Wherein, the first body 100 and the second body 200 can divide body formed, namely the first body 100 and each self-forming of the second body or directly selection standard part be then fixed together by retaining ring.Certainly, the first body 100 and the second body 200 also can adopt the modes such as precision casting one-body molded.
Preferably, as a kind of embodiment, see Fig. 2, be Spielpassung between the first body 100 and retaining ring 300.Namely see Fig. 2 and Fig. 8, the external diameter of the main paragraph 120 of the first body 100 is φ 1, and the internal diameter of retaining ring 300 is φ 3, φ 3 > φ 1.Arrange convenient for assembly like this.
Preferably, as a kind of embodiment, see Fig. 2, be Spielpassung between the second body 200 and retaining ring 300.Namely see Fig. 5 and Fig. 8, the external diameter of the second body 200 is φ 2, and the internal diameter of retaining ring 300 is φ 3, φ 3 > φ 2.Arrange convenient for assembly like this.
Wherein, the matching gap of above-mentioned Spielpassung is preferably 0.02mm to 0.4mm.
More excellent, the gap between the second body 200 and retaining ring 300 is greater than the gap between the first body 100 and retaining ring 300; I.e. φ 3-φ 2 > φ 3-φ 1.Be provided with like this to be beneficial to weld and stablize firmly.
Can there be multiple implementation in the gap that gap between second body 200 and retaining ring 300 is greater than between the first body 100 and retaining ring 300.Wherein, as a kind of embodiment, the internal diameter uniformity of retaining ring 300, the external diameter of the first body 100 is greater than the external diameter of the second body 200.Another mode of execution is the external diameter equal (directly can adopt standard piece) of the first body 100 and the second body 200, the internal diameter of retaining ring is not consistent, and namely the internal diameter of the second segment be coated on outside the second body 200 of retaining ring 300 is greater than the internal diameter being coated on the first paragraph outside the first body of retaining ring 300.
Preferably, wherein in an embodiment, see Fig. 3 and Fig. 4, the outer wall being coated on the part of retaining ring 300 inside of the first body 100 being provided with between the first lug boss 102, first lug boss 102 and retaining ring 300 is interference fit.See Fig. 3, the external diameter of the first lug boss 102 place first body is φ 11, now φ 11 > φ 3, and wherein φ 3 is for being coated on the internal diameter of the first paragraph of the retaining ring outside the first body 100.φ 11 > φ 3 > φ 1 in the present embodiment.
Wherein in an embodiment, see Fig. 6 and Fig. 7, the outer wall being coated on the part of retaining ring 300 inside of the second body 200 being provided with between the second lug boss 202, second lug boss 202 and retaining ring 300 is interference fit.See Fig. 3, the external diameter of the second lug boss 202 place second body is φ 21, now φ 21 > φ 3, and wherein φ 3 is for being coated on the internal diameter of the second segment of the retaining ring outside the second body 200.φ 21 > φ 3 > φ 2 in the present embodiment.First lug boss 102 and the second lug boss 202 are interference fit with retaining ring.First lug boss 102 and the second lug boss 202 are for location and fix, because the cooperation between retaining ring and the first body or the second body is Spielpassung, causing easily there is loose or dislocation between part weld parts dislocation etc. abnormal before welding, the first lug boss 102 and the second lug boss 202 being set and can making between part location and fixing.Wherein, the height h1 of the first lug boss and the height h2 of the second lug boss can be 0.02 to 0.4mm.And the first lug boss 102 is evenly arranged on the first body 100, the second lug boss 202 is evenly arranged on the second body 200.
