AI Technical Summary
Existing leak-sealing devices for tube heat exchangers are prone to jamming during removal and material deformation can cause water leakage, making them difficult to effectively seal leaks.
The design employs a sliding frame and an inner groove base. By using a sliding bar to push the sliding frame, the empty pressure ring is moved to a suitable position in the pipeline. The medium is then used to increase the volume of the compressed air ring chamber to fit the inner wall, achieving a leak-stopping effect and preventing jamming.
It improves the sealing effect, avoids jamming during removal, and enhances the reliability and efficiency of the sealing device.
