AI Technical Summary

Technical Problem

The sealing rings at the existing water pipeline connections are prone to wear and aging, leading to sealing failure. This makes it impossible to effectively compensate for the expansion of assembly gaps caused by thermal expansion and contraction and external disturbances, thus affecting the efficiency of water resource utilization.

Method used

A sealing compensation mechanism is adopted, including a drive unit and a compensation seal. The drive unit outputs axial force to push the compensation seal to fill the gap caused by wear of the sealing material or thermal expansion and contraction. Combined with an anti-backflow mechanism, it prevents pesticides and fertilizers from flowing back, ensuring the reliability of the sealing structure.

Benefits of technology

It effectively improves the fatigue resistance and service life of the sealing structure, prevents water pollution, and improves the efficiency of water resource utilization.
