一种弹簧预紧型穿墙止水环

By setting a groove on the outer wall of the steel pipe and fitting a convex ring on the inner wall of the pre-reserved opening filler, combined with a rubber flange and fastening bolts, the leakage problem caused by construction deviation and thermal expansion and contraction of the existing through-wall water-stop ring is solved, realizing the durability and reliability of the sealing structure and simplifying the maintenance process.

AI Technical Summary

Technical Problem

Existing through-wall water-stop rings have become leaky due to construction deviations, vibrations, and thermal expansion and contraction of steel pipes, leading to sealing failures and difficulties in repair, which affect the normal operation of the project.

Method used

A spring-preloaded through-wall water-stop ring is designed. By setting a groove on the outer wall of the steel pipe and matching the convex ring on the inner wall of the reserved opening filler, combined with a rubber flange, a rigid pressure plate and fastening bolts, the spring preload effect is achieved, ensuring a tight fit of the sealing structure.

Benefits of technology

It effectively prevents leakage, improves sealing durability, ensures long-term stable operation of the project, simplifies the maintenance process, and reduces project costs.
