AI Technical Summary
Thermal pipelines are prone to damage in high temperature, high pressure and corrosive environments. Existing seals are not firmly connected to the pipelines, leading to leaks and low efficiency of conventional emergency repairs.
A sealing tube with an annular groove and an annular air bladder was designed. High-pressure gas was introduced through the air inlet channel to drive the elastic seal, causing the annular air bladder to expand and tightly fit against the inner wall of the pipe, forming a stable radial sealing force. A guide tube was used to assist in installation to achieve rapid sealing.
It enables rapid repair of thermal pipelines, effectively blocks media leakage, improves repair efficiency, ensures system operation safety, prevents gas leakage, and ensures continuous and stable sealing process.

Abstract
Claims
1. A pipe seal for rapid repair of a heat pipe, characterized in that include: A sealing tube (10) has an annular groove (12) on both sides of its circumferential surface, and an annular airbag (20) is bonded in the annular groove (12). A flange (30) is fixedly fitted onto the surface of the sealing tube (10) and located between two sets of annular grooves (12). The flange (30) is provided with a moving channel (34), a sealing channel (32) and an air inlet channel (31) from the inside to the outside. An elastic sealing element is provided in the sealing channel (32). A flow channel (35) is provided in the sealing tube (10) between the moving channel (34) and the annular airbag (20). Gas is introduced into the intake channel (31). When the gas pressure in the intake channel (31) overcomes the elastic force of the elastic seal, the elastic seal moves downward into the moving channel (34), so that the intake channel (31) and the moving channel (34) are connected. The gas enters the annular airbag (20) through the moving channel (34) and the flow channel (35).
2. The pipe seal for quick repair of a thermal conduit according to claim 1, characterized in that: Both sides of the sealing tube (10) are integrally formed with guide tubes (11), and the diameter of the guide tubes (11) gradually decreases in the direction away from the sealing tube (10).
3. The pipe seal for quick repair of a thermal conduit according to claim 2, characterized in that: The elastic seal includes a sealing plug (33) adapted to the sealing channel (32) and a spring (36) disposed at the bottom of the sealing plug (33) and the moving channel (34).
4. The pipe seal for quick repair of a thermal conduit according to claim 3, wherein: It also includes an abutment rod (37) disposed at the bottom of the sealing plug (33).
5. The pipe seal for quick repair of a thermal conduit according to claim 4, characterized in that: The diameter of the air intake channel (31) is smaller than that of the sealing channel (32), and the diameter of the sealing channel (32) is smaller than that of the moving channel (34).
