AI Technical Summary

⚠Technical Problem

Traditional rubber combination joints are inconvenient to install when connecting flanges, easily cause wear on the sealing surface, and have low installation efficiency, relying on external tools.

⚗Method used

A low-temperature resistant rubber combination joint was designed, comprising a rubber tube body, a connecting flange, and a reinforced sealing gasket. By turning the handle, the diameter of the connector is reduced by driving the transmission threaded sleeve, which, together with the connecting rod, supports the flange connection, simplifying the installation process and improving stability.

🎯Benefits of technology

It simplifies the installation process of rubber combination joints, improves the stability and firmness of connecting flanges, reduces the risk of wear on sealing surfaces, and enhances wear resistance and thermal insulation performance.
