[0014] Compared with the existing technology, the utility model provides an assembled water supply and drainage pipeline with the following features:

[0015] Beneficial effects:

[0016] 1. Detachable and spliced piping system: A system has been designed that allows for quick assembly of water pipes and drain pipes through connectors and bolts. This system allows the pipes to be disassembled and reassembled using simple tools, improving the efficiency of pipe installation and maintenance.

[0017] 2. Coordination between the limiting slot and the fixed block: A limiting slot is provided inside the lower side of the cylindrical outer wall of the water supply pipe, which cooperates with the fixed block of the connector. This mechanical structure ensures the accurate positioning of the water supply pipe and the drain pipe when connected, and prevents deviation during the connection process.

Double sealing system with a sealing clamp and sealing ring: The sealing clamp at the lower end of the water supply pipe cooperates with the sealing groove at the upper end of the water supply pipe. The sealing clamp squeezes the sealing ring inside the sealing groove, allowing the sealing fluid to flow to the expansion ring, achieving a secondary seal. This design not only improves the sealing performance of the pipe connection, but also adapts to slight displacement of the pipe during use, preventing leakage.

[0021] 6. Dynamic sealing technology of sealing liquid and expansion ring: The sealing liquid flows to the expansion ring through the connecting pipe, causing the expansion ring to expand and fit tightly on the outer wall of the water supply pipe. This dynamic sealing technology can adapt to temperature changes and pressure fluctuations in the pipeline, ensuring the reliability of sealing performance under various working conditions.
