Problems solved by technology

These processing methods require operators to have higher operating skills, which also increase the processing procedures and prolong the working time, resulting in low working efficiency.
These connection structures will lead to the reduction of the strength of the water supply and drainage pipes at the processing position or the risk of leakage
These connection methods are very unfavorable for municipal activities that require high time and efficiency, such as emergency rescue of municipal drainage pipes.
In the emergency rescue of municipal water supply and drainage pipelines, since the pipelines are generally fixed, it is very inconvenient to disassemble, such as welding flanges and processing threads, it often takes a lot of time to disassemble and assemble the pipelines, which greatly affects the efficiency of emergency management

Embodiment Construction

[0019] Such as Figure 1 to Figure 3 As shown, a municipal water supply and drainage pipe connection structure, which includes a circular connecting body 6 and a sealing unit arranged between the connecting body 6 and the pipeline 1, the center of the connecting body 6 is provided with a The through hole for the fluid, the right end of the connecting body 6 is a circular connecting flange 7, and the center of the left end is provided with an axial mounting hole 16, the pipe 1 is inserted in the mounting hole 16 and is slidingly fitted with the connecting body 6 . The present invention is used in pairs, and the connecting body 6 can slide axially along the pipe 1, so that the distance between the end of the pipe 1 and the connecting flange 7 can be adjusted, so that the distance between the end faces of the two pipes 1 to be connected can be adjusted. The accuracy requirement is not high, which is especially suitable for pipeline 1 rescue. When the pipeline 1 leaks, it is onl...

Abstract

The invention discloses a connection structure of municipal water supply and drainage pipelines, which comprises a connecting body and a sealing unit arranged between the connecting body and the pipeline. One end of the body is a connecting flange, and the center of the other end is provided with an axial mounting hole, and the pipe is installed in the mounting hole and is in sliding fit with the connecting body. The present invention is used in pairs and does not have high requirements for the accuracy of the distance between the end faces of the two pipes to be connected, which is especially suitable for emergency operations of municipal pipes, with high efficiency during operation, rapid connection, high reliability, low labor intensity and No disassembly of the pipe is required. A tapered compression sleeve is arranged between the invention and the pipeline, and the compression sleeve is tightened between the pipeline and the movable flange by a set screw so that the pipeline and the movable flange are fixedly connected. The present invention does not need to use special tools during installation, and does not require high operating skills of operators.

Description

technical field [0001] The invention relates to the technical field of connection of water supply and drainage pipes, in particular to a connection structure of municipal water supply and drainage pipes. Background technique [0002] Municipal construction is an important part of municipal activities. Its purpose is to prosper the urban economy, facilitate the production and living environment of citizens, and promote the development of the city's material and spiritual civilization. [0003] At present, the connection of water supply and drainage pipes in municipal construction and construction requires configuration processing at the connection end, such as welding flanges, and then fixing them with bolts, or using pipe clamps to connect after processing threads at the ends. These processing methods require operators to have higher operating skills, and also increase the processing steps, prolong the working time, and result in low working efficiency. These connection str...
