Description

Technical Field

[0001] The utility model belongs to the technical field of water supply and drainage pipelines, and in particular relates to a water supply and drainage pipeline connecting device. Background Art

[0002] Water supply and drainage pipelines are pipes (channels) that transport and distribute industrial water supply and domestic drinking water, and collect, transport and discharge industrial wastewater, domestic sewage and rainwater. Water supply and drainage pipelines are an important part of water supply and drainage pipeline projects, and water supply and drainage pipeline projects are an integral part of the water supply and drainage system, playing an important role in the entire water supply and drainage system. Water supply and drainage pipeline projects include the pipe (channel) system itself and various structures on the pipe (channel) system. Drainage pipes are divided into main drainage pipes and branch drainage pipes. Main drainage pipes are usually pipes with larger diameters and stronger carrying capacity. They are responsible for connecting various branch drainage pipes and equipment. Branch drainage pipes are usually set with different diameters and layouts according to needs, and some branch drainage pipes usually need to be connected to meet the actual needs of the project.

[0003] Most of the existing water supply and drainage pipe connection devices are flange seats, which are screwed to the water supply and drainage pipes, and then the two sets of flange seats are fastened together by fixing bolts to achieve the connection of the water supply and drainage pipes. Since the bolt flange connection usually requires the use of a large number of bolts, each bolt needs to be removed one by one during disassembly, which is time-consuming and labor-intensive, and increases the difficulty of disassembly. At the same time, during the disassembly process, the bolts may be damaged or deformed, making them unusable and requiring replacement with new bolts, increasing maintenance costs.
