Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage pipe connection, in particular to a water supply and drainage pipe connection device. Background Technique

[0002] The water supply and drainage system is a general term for facilities that provide water supply and wastewater drainage for people's living, production, municipal administration, and fire protection. The water supply and drainage system is an essential and important part of any building. The water supply and drainage system of a general building includes a domestic water supply system, a domestic wastewater drainage system, and a fire protection system. Drainage pipes refer to a system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater, including main pipes, branch pipes, and pipes leading to treatment plants. Whether built on the street or anywhere else, as long as it plays a drainage role, it should be regarded as a drainage pipe system.

The utility model is beneficial to sealing the pipeline by providing a connection sealing sleeve. A plurality of connection sealing inner sleeves are arranged at the connection between the pipeline and the connection device, making its sealing performance better.
