AI Technical Summary
The existing sealed cavity design of pressurized plugging fixtures causes the leaking medium to diffuse irregularly, making it impossible to accurately guide it to the leak point, resulting in low targeting and sealing reliability of the glue injection sealing operation.
It adopts a segmented sealing cavity design, forming an independent leak-sealing cavity through the clamping components and the partition. The leaking medium itself is used to trigger the discharge of the sealing adhesive, achieving precise positioning and sealing, and avoiding the irregular diffusion of the medium.
It improves the accuracy and reliability of the glue injection operation, enhances the precision and response speed of the sealing operation, and reduces the waste of sealing glue.
