Background

In the prior art, pipeline welding is to assemble and weld a pipeline and a pipe fitting into a whole to form a pipeline system, and is widely applied to various industries such as metallurgy, petrifaction, mechanical manufacturing and the like. In the pipeline welding process, the elbow is often adopted to change the pipeline direction, and according to the bending radius difference, the elbow that commonly uses has pushing away system elbow, welding elbow, punching press elbow etc. but this kind of mode of changing the route has certain drawback, and when adjacent pipeline interval is less, especially when the pipeline needs 180 gyrations, elbow bending radius is great, can't carry out effective connection with adjacent pipeline.

In this case, the conventional connection method is to adopt straight pipe butt joint. The mode not only increases the workload, but also increases the welding difficulty and the pipeline resistance, the welding quality can not be ensured, and the service life is influenced.

The invention is realized by the following technical scheme: a double-hole communication pipe cap is used for communicating a first pipe body and a second pipe body which are adjacent in position and opposite in flow direction, and the pipe cap is of an integrated structure consisting of a cap edge, a cap edge and a cap bottom; the cap edge is a port edge of the pipe cap, and comprises a first port edge section used for being connected with the first pipe body, a second port edge section used for being connected with the second pipe body, and two sunken edge sections used for smooth transition between the first port edge section and the second port edge section; the inner part of the cap bottom is in a bowl bottom shape with smooth flow guide between the first pipe body and the second pipe body; the cap edge is a flow guide tube wall between the cap edge and the cap bottom.

Preferably, the pipe cap is connected with the first pipe body and the second pipe body through welding seams, and each welding seam comprises a first port edge section, a second port edge section and two sunken edge sections.

In addition, it is preferable that an outer wall of the first port edge section protrudes from an outer wall of the first tube; the outer wall of the second port edge segment projects beyond the outer wall of the second tube.

The beneficial effects are that: compared with the prior art, the invention effectively solves the problems of small distance between adjacent pipelines and incapability of connecting, reduces the welding difficulty, ensures the welding quality, prolongs the service life of the pipelines, and reduces the resistance of the pipeline because the interior of the double-hole communication pipe cap is bowl-shaped and smooth.

Detailed Description

As shown in fig. 1 to 5, a dual hole communication cap is used to communicate a first tube 100 and a second tube 200 which are adjacent to each other but have opposite flow directions, wherein the first tube 100 and the second tube 200 have a center distance L, an inner diameter D1 and an outer diameter D2, and the center distance L between the first tube 100 and the second tube 200 is greater than or equal to D2. The pipe cap is an integrated structure consisting of a cap edge 1, a cap edge 2 and a cap bottom 3; the cap rim 1 is a port edge of a pipe cap, the cap rim 1 includes a first port edge section 11 for connecting the first pipe 100 and a second port edge section 12 for connecting the second pipe 200, and further includes two recessed edge sections 13 for smooth transition between the first port edge section 11 and the second port edge section 12, the radius of the inner cavity of the first port edge section 11 and the second port edge section 12 is R1, preferably D1=2R1, the center distance between the first port edge section 11 and the second port edge section 12 is also L, that is, the cap rim 1 forms a closed 8-shaped cap rim 1 from the first port edge section 11 to the recessed edge section 13 on one side, then to the second port edge section 12, then to the recessed edge section 13 on the other side, and finally back to the first port outer edge section 11, the cap rim 1 achieves a smooth transition with the inner cavity of the adjacent first pipe 100 and second pipe 200, the pipe cap is connected with the first pipe body 100 and the second pipe body 200 through a welding seam, the welding seam comprises a cap edge 1 surrounded by a first port edge section 11, a second port edge section 12 and two concave edge sections 13, the workload of sealing and welding between the cap edge 1 and the first pipe body 100 and the second pipe body 200 is small, and the welding difficulty is small by adopting a circumferential welding mode; the inside of the cap bottom 3 is in a bowl bottom shape with smooth flow guiding between the first pipe 100 and the second pipe 200, so that the resistance of fluid in a pipeline is reduced; the cap edge 2 is a flow guide pipe wall between the cap edge 1 and the cap bottom 3.
