AI Technical Summary
Technical Problem
The outer ring of traditional sealing rings is easily scratched and damaged, which can lead to breakage in severe cases. In addition, they have poor anti-slip performance and connection stability.
Method used
Design an oil pipe sealing ring with a spiral drainage groove. It adopts a structure of No. 1 oil pipe, No. 2 oil pipe and flange ring, combined with a tensioning mechanism, retaining ring and connecting bolts. The spring force is used to make the sealing ring fit tightly, and the fluid flow is guided by the spiral groove to enhance the sealing effect.
Benefits of technology
