AI Technical Summary

Technical Problem

Traditional water pipe connection structures suffer from low installation efficiency, insufficient sealing, and high maintenance costs. NW16 type connectors are also prone to leakage due to cost constraints, manufacturing difficulties, and other factors.

Method used

The design features a small machining allowance for the flange ring. By setting a limiting protrusion and an expansion position on the pipe body, the NW16 connector is fitted onto the outside of the pipe body and fixed by the expansion, forming an integrated structure that avoids welding and ensures sealing and stability.

Benefits of technology

The NW16 quick-connect plug achieves efficient installation and leak-free connection, reducing costs and improving connection stability and convenience.
