Embodiment
Further illustrate technical scheme below with reference to the accompanying drawings and specific embodiments.
Embodiment one
As shown in Figure 1, Figure 2 and shown in Fig. 3, a kind of elbow for being provided in the present embodiment one, including the first pipeline 1, second pipe Road 2 and interface channel 3, the first pipeline 1 and second pipe 2 are arranged side by side, and symmetrically, the first pipeline 1 and second pipe 2 Contact line be line of symmetry, the first connecting hole 11 is provided with the first pipeline 1, is provided with second pipe 2 and the first connecting hole Second connecting hole 21 of 11 position correspondences, namely the first connecting hole 11 and the second connecting hole 21 are on the first pipeline 1 and the first pipe The contact line in road 2 is symmetrical, and respectively on the medial surface of the first pipeline 1 and second pipe 2.The both ends difference of interface channel 3 It is inserted into the first connecting hole 11 and the second connecting hole 21, and is tightly connected with the first connecting hole 11 and the second connecting hole 21, even Road 3 is connected to turn on the first pipeline 1 and second pipe 2.Close the first adjacent pipeline 1 and second is managed by interface channel 3 Road 2 turns on, so as to eliminate the bent portion of elbow and realize the turning of fluid.
As shown in Figure 3 and Figure 4, the both ends of interface channel 3 connect preferably by welding manner and the first connecting hole 11, second Hole 21 is connect to be tightly connected, it will usually the finished edge on interface channel 3, the first connecting hole 11 and the second connecting hole 21, so as to It is welded to connect in interface channel 3 and the first connecting hole 11, the second connecting hole 21.Interface channel 3 be internally provided with one or The multiple through holes of person, are preferably one, rectangle for circular, ellipse and with two arc sides of the shape of the flow area of through hole or Other combined shapeds of person.
The pipe that for the first pipeline 1 and second pipe 2 can be the pipeline of end-enclosed or end is opening Road.Further, when the end of the first pipeline 1 and second pipe 2 is opening, it will usually in the first end of the first pipeline 1, i.e., Right end is illustrated, the first plug 12 is set, the first plug 12 can be used for the end of the first pipeline 1 of sealing;The first of second pipe 2 End, that is, illustrate right end, sets the second plug 22, and the second plug 22 can be used for the end of sealing second pipe 2.When interface channel 3 When end from the first pipeline 1 and second pipe 2 is nearer or the first pipeline 1 and 2 caliber of second pipe it is larger, welding personnel energy , can also be by stretching into welding equipment from the first plug 12 and the second termination 22 when enough entering the first pipeline 1 and second pipe 2 Or welding personnel carries welding equipment and is directly entered the first pipeline 1 and second pipe 2, and interface channel 3 is welded.
In order to enable the first pipeline 1, second pipe 2 are connected and sealed with the first plug 12, the second plug 22, further , the right end of the first pipeline 1 is fixedly connected by welding manner with the first plug 12, and the right end of second pipe 2 passes through welding side Formula is fixedly connected with the second plug 22.When actual welding connects, outer groove is set on the first plug 12 and the second plug 22, so After be welded to connect.
When the first pipeline 1 is the pipeline of end-enclosed, in order to enable interface channel 3 further, may be used also easy to welding To set the first skylight 13 and the first cover board 14 on the first pipeline 1, the first skylight 13 is preferably placed at and the first connecting hole 11 On the lateral surface for putting corresponding first pipeline 1, welding equipment is facilitated to be stretched into from the first skylight 13 in the first pipeline 1 to interface channel 3 are welded to connect with the first connecting hole 11.The shape of first skylight 13 is rectangle, ellipse or other beneficial to the shape welded Shape, the first cover board 14 are adapted with the shape of the first skylight 13, and are fixedly connected by welding manner with the first skylight 13.
When second pipe 2 is the pipeline of end-enclosed, in order to enable interface channel 3 further, may be used also easy to welding To set the second skylight 23 and the second cover board 24, the second skylight 23 and 24 set-up mode of the second cover board and on second pipe 2 One skylight 13 is similar with 14 set-up mode of the first cover board, and the first skylight 13 and the second skylight 23 are on the first pipeline 1 and first The contact line of pipeline 2 is symmetrical.Second cover board 24 is adapted with the shape of the second skylight 23, and passes through welding manner and the second skylight 23 are fixedly connected.
It is further preferred that when the first pipeline 1 and 2 caliber of second pipe is smaller or other reasons, only set plug and Or when being difficult to meet requirement that welding equipment welds interface channel during skylight, can set at the same time the first plug 12, Second plug 22, the first skylight 13, the first cover board 14, the second skylight 23 and the second cover board 24, so as to by interface channel 3 and One pipeline 1 and second pipe 2 are welded to connect.
The further technical solution of the present invention, elbow provided by the invention are suitable for the first pipeline 1 and second pipe 2 side by side Facilities, i.e., can have a certain distance or the first pipeline 1 and the second pipe between the first pipeline 1 and second pipe 2 The distance between road 2 is zero.The central axes and the central axes of second pipe 2 for being particularly suitable for the first pipeline 1 are parallel to each other, and first Pipeline 1 is in contact with second pipe 2, namely the situation that the distance between the first pipeline 1 and second pipe 2 are zero, meets first The sum of the outside diameter d 1 of pipeline 2 and the outside diameter d 2 of second pipe 3 are equal to the outer diameter D of elbow.The elbow of this structure overcomes existing The problem of needing to bend shaping when processing elbow in technology.The thickness of interface channel 3 can be according to the first pipeline 1 and second pipe 2 wall thickness and set, therefore will not occur pipe deforming and it is thinned the problem of.The circulation area of interface channel 3 also can be according to reality Border needs and designs, therefore is not in the irregular problem of circulation area.
