A sealing process

Abstract

This invention discloses a sealing process, including pretreatment to clean impurities from the surface of the sealing element; pre-assembly to check for deformation of the pretreated sealing element; if no deformation is found, pre-assembly is performed; if deformation exists, the deformed surface of the sealing element is repaired to maintain consistent gaps between the sealing elements, followed by pre-assembly; adhesive application to apply adhesive to the gaps between the sealing elements using an adhesive application device; and evaluation to assess the uniformity, thickness, and curing degree of the coating. The adhesive application device includes a uniform coating component for smoothing the sealant. This application uses an adhesive application device to apply sealant to the gaps between the sealing elements, and the uniform coating component simultaneously smooths the sealant during the application process, completing both steps simultaneously, thus improving sealing efficiency. Furthermore, the immediate smoothing of the sealant after application ensures a uniform distribution of sealant around the weld, significantly reducing the probability of re-contamination around the weld and guaranteeing a tight seal.
