AI Technical Summary
Technical Problem
Traditional gas pipeline sealing rings cannot self-repair, leading to sealing failure, high maintenance costs, and complex and unreliable external glue injection repair operations.
Method used
A self-healing gas pipeline sealing ring was designed, comprising a coaxially arranged annular groove and a connecting channel. An internal piston structure and spring provide pre-tightening force. By rotating a screw to puncture the glue capsule, the glue can automatically seep out and cure, forming a sealing layer.
Benefits of technology
It achieves automatic repair function of the sealing ring, improves sealing reliability and service life, reduces maintenance costs, and is suitable for high pressure and corrosive environments.

Abstract
This invention provides a self-healing gas pipeline sealing ring, comprising a sealing ring body. The sealing ring body has a first annular groove and a second annular groove arranged coaxially inside, with the first annular groove located outside the second annular groove. The first annular groove and the second annular groove are connected by multiple connecting channels. A retractable piston structure is provided within the first annular groove, and a spring is provided inside the piston structure to provide a constant preload force. A groove is provided on the outer side of the sealing ring body, and a threaded groove is provided at the bottom of the groove. This invention is simple and reliable, solving the problem of traditional sealing rings' inability to self-repair and overcoming the drawbacks of complex external adhesive injection operations. It significantly improves the reliability and service life of gas pipeline seals, and is particularly suitable for harsh working environments such as high pressure and corrosive conditions.
