Description

Assembled communicating pipeline Technical Field The invention belongs to the field of pipelines, and particularly relates to an assembled communication pipeline. Background A filter is an indispensable device on the medium carrying pipeline. Impurities in the medium can be filtered out by the filter. The existing three-way pipe is provided with an opening at one position, the three-way pipe is connected into a pipeline through two other openings, a medium at the inlet end conveniently penetrates through the filter and returns into the three-way pipe from the filter, the medium is discharged from the other opening, an inner through pipe used for communicating the filter is arranged in the three-way pipe, one end of the inner through pipe is communicated with the opening at one position, the other end of the inner through pipe extends to the opening at the other position (shown in fig. 1) and is connected with the filter, the existing three-way pipe is generally formed by integrally casting, and the inner through pipe and the three-way pipe are integrally arranged. The problems of shrinkage, air holes, slag inclusion, cracks and the like easily occur in the production of copper castings in the prior art, the structure of the inner tube arranged in the three-way tube is complex and inconvenient to detect when the inner tube is of an integrated structure, and the structure of a corresponding die used in the processing of the three-way tube is complex and is not beneficial to the production and processing, the product quality of the processed copper castings is directly affected, and the production qualification rate is reduced.
