[0002] Water supply and drainage pipes refer to pipeline materials used to transport and discharge water. They are mainly divided into two categories: water supply pipes and drainage pipes. They are widely used in construction, urban infrastructure construction and other fields to supply domestic water, fire-fighting water, and to remove domestic sewage, rainwater, etc. When selecting water supply and drainage pipes, factors that need to be considered include corrosion resistance, pressure resistance, installation ease, cost, service life and environmental adaptability. Different types of pipes have their own advantages and disadvantages, and should be selected according to actual needs and application scenarios.

[0003] Common water supply and drainage pipes have a relatively simple structure and certain functional limitations during installation and use. Anti-backflow devices are usually not installed, which may cause water backflow, causing sewage or harmful substances to flow back into the water supply system, polluting domestic water and posing a threat to human health. Backflowing water may damage water pumps, valves and other water supply and drainage equipment, increase maintenance costs and downtime, and bring certain adverse effects to people's use process. For this reason, we propose a new type of environmentally friendly, pressure-resistant and corrosion-resistant water supply and drainage pipe. Utility Model Content
