AI Technical Summary

Technical Problem

Existing water flow indicators are prone to leakage under high pressure due to the gasket easily shifting from the sealing position. Furthermore, the gasket is not strong enough and is easily deformed under high pressure, causing leakage.

Method used

The ring-shaped gasket, sealing ring, and ring-shaped expansion rib are integrated into one piece. The cooperation between the nut and the threaded rod ensures that the cover plate stably covers the mounting base. The tight seal is achieved by the compression of the ring-shaped gasket and sealing ring, preventing the seal from shifting.

Benefits of technology

The sealing performance and water pressure resistance of the water flow indicator have been improved, preventing water leakage and ensuring the stability and practicality of the seals.
