Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipes, in particular to a pipe butt flange structure for a sewage pipe network. Background Art

[0002] The sewage pipe system consists of pipes and their ancillary structures for collecting and transporting urban sewage. Sewage flows from branch pipes into trunk pipes, then into the main pipe, and finally into the sewage treatment plant. The pipes are distributed from small to large, similar to rivers and in a tree-like shape, which is completely different from the circulation and penetration of the water supply network. Sewage generally flows from high to low in the pipe by relying on the water level difference at both ends of the pipe. The inside of the pipe is not under pressure, that is, it flows by gravity. At present, people on the market often use butt flanges when connecting sewage pipes.

[0003] The prior art patent document with publication number CN208605777U provides a pipe connecting flange, in which the first ring plate and the second ring plate can slide on the pipe, so this will not affect the installation and disassembly of the two flanges. Secondly, after the first ring plate, the annular cover plate and the second ring plate are connected, the first flange and the second flange will not be exposed to the atmosphere, thereby avoiding corrosion of the first flange, the second flange and their connecting parts. However, the flange in the prior art generally does not have multiple sealing and waterproof functions, thereby reducing the need for the use of the flange structure. Therefore, we need a pipe docking flange structure for a sewage pipe network. Utility Model Content
