The device not only ensures the distribution and dispatching of water volume in the water delivery pipeline, but also meets the specific requirements of the project.

[0015] The T-shaped diversion bin is integrally formed with branch pipes A and B. Branch pipes A and B are required to be laid in parallel with the main pipe. This structure has the functions of water diversion and diversion. The pipeline interface protective layer wraps the pipe interface tightly to play a role of heat preservation and pressure resistance.
