Description
Technical Field
[0001] This utility model relates to the field of flange sealing technology, and in particular to the auxiliary sealing ring structure of anti-drip pipe flanges. Background Technology
[0002] In industrial production and various pipeline systems, flange connections are widely used due to their ease of installation and disassembly. However, with the development of industrial technology, equipment operating conditions are becoming increasingly demanding, requiring higher performance from sealing components in terms of high temperature, high pressure, and strong corrosion resistance. To address these challenges, anti-drip pipe flange sealing rings have emerged, aiming to provide more reliable sealing performance, reduce leakage risks, and ensure the safe and stable operation of pipeline systems. The anti-drip pipe flange sealing ring market is currently driven by both technological upgrades and expanding demand, with high-performance materials, intelligent integration, and green manufacturing as its core development directions. It is breaking through technological bottlenecks through industry-academia-research collaboration and continuous technological innovation.
[0003] Flange sealing rings undergo elastic deformation under external pre-tightening force, tightly filling the microscopic gaps between the flange faces to form a seal and prevent leakage. Existing technologies often use fixed structures for sealing protection, which have complex internal structures, are difficult to install, and are complicated to disassemble during later maintenance projects, increasing maintenance time costs, reducing maintenance efficiency, decreasing practicality, and narrowing the scope of application.

The sealing ring 21 squeezes the rubber gasket 20 to deform it, achieving a better seal. When the air pump 203 is started, the fixed block 204, which is fixedly connected to the air pump 203, moves the drive plate 205, allowing the drive plate 205 to slide horizontally left and right along the displacement groove 202 on the fixed frame 201. The limit groove 206 and the first column 207 and the second column 208 cooperate with each other to make the hollow tube 210 and the fixed rod 209 rotate in different directions.
