Embodiment 1

[0038] Such as figure 1 , figure 2 as well as image 3 As shown, the elbow provided in the first embodiment includes a first pipe 1, a second pipe 2 and a connecting channel 3. The first pipe 1 and the second pipe 2 are arranged side by side and are symmetrical to each other. The first pipe 1 The line of contact with the second pipe 2 is a line of symmetry, the first pipe 1 is provided with a first connection hole 11, and the second pipe 2 is provided with a second connection hole 21 corresponding to the position of the first connection hole 11, that is, the second A connection hole 11 and a second connection hole 21 are symmetrical with respect to the contact line of the first pipe 1 and the first pipe 2 , and are located on the inner sides of the first pipe 1 and the second pipe 2 respectively. The two ends of the connection channel 3 are respectively inserted into the first connection hole 11 and the second connection hole 21, and are sealed with the first connection hol...

Embodiment 2

[0047] A kind of processing method that is used for above-mentioned elbow provided in this embodiment is implemented according to the following steps:

[0048] Step S00: Determine the processing size of the connecting passage 3 according to the size and shape of the first pipe 1 and the second pipe 2, specifically determine the connecting passage 3 through the diameter, wall thickness and shape of the first pipe 1 and the second pipe 2. Diameter, wall thickness and shape, and at the same time determine the installation position of the connecting channel 3.

[0049] Step S10: according to the processing size in step S00, the lathe processes the connecting channel 3. In order to facilitate the welding connection, the groove can also be processed on the connecting channel 3 by the lathe.

[0050] Step S20: welding the two ends of the connecting channel 3 and the auxiliary components to the first pipeline 1 and the second pipeline 2 respectively. Specifically, the first connectin...

Embodiment 3

[0057] The difference between embodiment three and embodiment two is that in step S20, during the specific welding connection, the following steps are implemented:

[0058] Step S2020: welding the two ends of the connecting channel 3 to the first pipeline 1 and the second pipeline 2 respectively. Specifically, the two ends of the connection channel 3 are respectively welded to the first connection hole 11 of the first pipe 1 and the second connection hole 21 of the second pipe 2 .

[0059] Step S2021: welding the first cover plate 14 and the second cover plate 24 to the first sunroof 13 and the second sunroof 23 respectively.

[0060] Step S2022: welding the first plug 12 and the second plug 22 to the end of the first pipeline 1 and the end of the second pipeline 2 respectively.

[0061] That is to say, in the actual welding process, the plug can be welded first, and then the cover plate can be welded; or the cover plate can be welded first, and then the plug can be welded. ...

Abstract

The invention relates to an elbow, which includes a first pipe, a second pipe and a connecting channel, the first pipe and the second pipe are arranged side by side, the first pipe is provided with a first connecting hole, the The second pipe is provided with a second connection hole corresponding to the position of the first connection hole, and the two ends of the connection channel are respectively inserted into the first connection hole and the second connection hole, and are connected to the first connection hole. The first connection hole and the second connection hole are sealed and connected, and the connection channel connects the first pipe and the second pipe. The elbow disclosed by the invention is simple to manufacture, has strong versatility, does not have the problem of deformation and thinning of the fluid turning part of the elbow, and the flow area can be designed according to actual needs. The invention also relates to a method for processing an elbow, which can be processed by a lathe and / or an angle grinder.

Description

technical field [0001] The invention relates to an elbow and a processing method for manufacturing the elbow. Background technique [0002] The size of the space occupied by the pipeline is usually the key to determine whether the pipeline can be used normally in some special fields. To connect two closely adjacent pipes, the outer diameter of the elbow is required to be the sum of the outer diameters of the two pipes, which puts forward a higher manufacturing requirement for the elbow connecting the above two pipes. [0003] At present, the above-mentioned elbows that are often used are usually made by pressing pipes. Since the pipes are easily deformed during the pressing process, it is easy to cause thinning, wrinkling or deformation of the pipe wall thickness, and it is difficult to ensure the ellipticity of the bends. , it is easy to cause irregular size of the circulation area, and special equipment is required in the pressing process, the processing process is compli...
