Description

Technical Field

[0001] The invention belongs to the technical field of experimental testing, and in particular relates to a pipeline diversion device with double semicircular rings and electromagnetic self-locking seal. Background Art

[0002] Pipeline connections are a crucial step in testing and experimentation. Threaded connections are the primary method used in both testing and actual production. Currently, most pipe diversion devices are tees, crosses, and five-way pipes. While secure, threaded connections can be time-consuming and unreliable due to thread wear. Furthermore, most tees, crosses, and five-way pipes use threaded connections, which cannot solve the connection problem of non-threaded pipes.

[0003] For non-threaded pipes, flanges are usually welded at the ends of the pipes to connect the two pipes. Welding flanges takes a lot of work hours, and the connection between the pipe after the flange is welded and other pipes is limited. Other pipes must also have flanges of the same specifications. The flexibility of pipe use is insufficient. If the pipe is used again, the existing flange needs to be removed and a flange of a new specification needs to be welded. Summary of the Invention
