[0002] The traditional method of connecting rubber-lined pipes is generally to connect and fix them directly through two connecting flanges and the cooperation of bolts and nuts. However, in actual long-term use, due to the presence of gaps at the connection between the two rubber-lined pipes, the rubber lining at this location is relatively easy to flip up or break, thereby greatly reducing the service life of the rubber-lined pipes. Therefore, an improved technology is urgently needed to solve this problem existing in the existing technology.

[0003] For example, the publication number is CN215371446U, which is a docking structure for rubber-lined pipes. The structure includes an outer surrounding ring arranged on the periphery of a center ring, an inner retaining ring arranged on the inner side of the center ring, and the two sides of the center ring are respectively connected to the connecting flanges of the two rubber-lined pipes. The inner diameter of the center ring is consistent with the inner diameter of the connecting flange and the outer diameter of the inner retaining ring. There are two pressure ring assemblies, which are respectively arranged on the outer sides of the connecting flanges through bolts and nuts. The outer diameter of the pressure ring assembly is consistent with the inner diameter of the outer surrounding ring. The utility model has a reasonable structure. By setting the center ring and protecting the inner retaining ring, the gap at the connection of the two rubber-lined pipes can be blocked, thereby avoiding the rubber lining at the connection of the rubber-lined pipes from turning up or being damaged, greatly improving the service life of the rubber lining, and facilitating installation and disassembly, and ensuring the sealing of the connection of the rubber-lined pipes.
