Embodiment
Below in conjunction with accompanying drawing and the technical scheme of the present invention is described further by embodiment.
Embodiment one
Such as Fig. 1, shown in Fig. 2 and Fig. 3, a kind of elbow provided in the present embodiment one, comprise the first pipeline 1, second pipe 2 and connecting passage 3, first pipeline 1 and second pipe 2 are arranged side by side, and symmetrically, the osculatory of the first pipeline 1 and second pipe 2 is symmetric line, first pipeline 1 is provided with the first connection hole 11, second pipe 2 is provided with the two connection hole 21 corresponding with the first connection position, hole 11, also namely the first connection hole 11 and the 2nd connection hole 21 are symmetrical about the osculatory of the first pipeline 1 and the first pipeline 2, and lay respectively on the interior side of the first pipeline 1 and second pipe 2. the two ends of connecting passage 3 be inserted into respectively the first connection hole 11 and the 2nd connection hole 21 in, and is connected with first hole 11 and the 2nd connect hole 21 be tightly connected, connecting passage 3 is by the first pipeline 1 and second pipe 2 conducting. by connecting passage 3 by the first closely adjacent pipeline 1 and second pipe 2 conducting, thus eliminate the curved part of elbow and achieve the turning of fluid.
As shown in Figure 3 and Figure 4; the two ends of connecting passage 3 are connected hole 11, the 2nd connection hole 21 preferably by welding process with first and are tightly connected; usually can connect at connecting passage 3, first on hole 11 and the 2nd connection hole 21 and process groove, so that connecting passage 3 is connected hole 11, the 2nd with first connects being welded to connect of hole 21. The inside of connecting passage 3 is provided with one or more through hole, it is preferable to one, and the shape of the flow area of through hole is circular, oval and has rectangle or other combined shaped on two arc limits.
Can be the pipeline that end is closed for the first pipeline 1 and second pipe 2, it is also possible to be end be the pipeline of opening. Further, when the end of the first pipeline 1 and second pipe 2 is opening, usually at the first end of the first pipeline 1, can namely illustrate right-hand member, the end that first stifled 12, first stifled 12 can be used for sealing the first pipeline 1 is set; At the first end of second pipe 2, namely illustrate right-hand member, the end that the 2nd stifled the 22, two stifled 22 can be used for sealing second pipe 2 is set. When connecting passage 3 is close to the end of the first pipeline 1 and second pipe 2 or the first pipeline 1 and second pipe 2 caliber bigger, when welding personnel can enter the first pipeline 1 and second pipe 2, by stretching into welding set from first stifled 12 and the 2nd termination 22 or welding personnel carries welding set and directly enters the first pipeline 1 and second pipe 2, connecting passage 3 can also be welded.
In order to make the first pipeline 1, second pipe 2 and first stifled the 12, the 2nd stifled 22 be connected and sealed, further, the right-hand member of the first pipeline 1 is fixedly connected with by welding process stifled with first 12, and the right-hand member of second pipe 2 is fixedly connected with by welding process stifled with the 2nd 22.When actual welding connects, first stifled 12 and the 2nd stifled 22 arrange outer groove, is then welded to connect.
When the first pipeline 1 is the pipeline that end is closed, in order to make connecting passage 3 be convenient to welding, further, first skylight 13 and the first cover plate 14 can also be set on the first pipeline 1, first skylight 13 is preferably placed on the outer side with the first first pipeline 1 corresponding to connection position, hole 11, facilitates welding set to stretch into from the first skylight 13 and in first pipeline 1, with first, connecting passage 3 is connected hole 11 and is welded to connect. The shape in the first skylight 13 is rectangle, ellipse or other shape being beneficial to welding, and the profile in the first cover plate 14 and the first skylight 13 is suitable, and is fixedly connected with the first skylight 13 by welding process.
When second pipe 2 is the pipeline that end is closed, in order to make connecting passage 3 be convenient to welding, further, 2nd skylight 23 and the 2nd cover plate 24 can also be set on second pipe 2,2nd skylight 23 and the 2nd cover plate 24 set-up mode and the first skylight 13 and the first cover plate 14 set-up mode are similar, and the first skylight 13 and the 2nd skylight 23 symmetrical about the osculatory of the first pipeline 1 and the first pipeline 2. The profile in the 2nd cover plate 24 and the 2nd skylight 23 is suitable, and is fixedly connected with the 2nd skylight 23 by welding process.
Preferred further, when the first pipeline 1 with second pipe 2 caliber is less or other reasons, only arrange stifled head and or when being difficult to meet requirement that connecting passage is welded by welding set during skylight, first stifled the 12, the 2nd stifled 22, first skylight 13, first cover plate 14, the 2nd skylight 23 and the 2nd cover plate 24 can be set simultaneously, connecting passage 3 and the first pipeline 1 and second pipe 2 to be welded to connect.
The further technical scheme of the present invention, elbow provided by the invention is applicable to the first pipeline 1 and second pipe 2 is arranged side by side situation, namely can there is certain distance between the first pipeline 1 and second pipe 2, it is also possible to be the distance between the first pipeline 1 and second pipe 2 be zero. The axis of the axis and second pipe 2 that are particularly useful for the first pipeline 1 is parallel to each other, first pipeline 1 contacts with second pipe 2, namely also distance between the first pipeline 1 and second pipe 2 is the situation of zero, and outside diameter d 2 sum of the outside diameter d 1 and second pipe 3 that meet the first pipeline 2 equals the outer diameter D of elbow. The elbow of this kind of structure overcomes to be needed when processing elbow in prior art to bend shaping problem. The thickness of connecting passage 3 can be arranged according to the wall thickness of the first pipeline 1 and second pipe 2, therefore also there will not be pipe deforming and subtract thin problem. The circulation area of connecting passage 3 also can design according to actual needs, therefore the problem that there will not be circulation area irregular.
