Description

Technical Field

[0001] The utility model relates to the field of mechanical seals, and particularly to a sealant device for inlaying a sealing ring. Background Art

[0002] Inlay rings are widely used in the field of mechanical seals. When two different materials are inlaid, the metal seat of the inlay ring and the sealing ring are combined together with a certain interference fit. Due to various reasons such as the surface finish and roundness of the inlay area, there may be gaps at the joint between the metal seat and the sealing ring, forming leakage channels. In the prior art, in order to seal the leakage channels, sealant is used for filling. The inlaid seal product is placed in a container filled with glue solution, soaked in the glue solution, and the glue solution is filled into the gaps by means of pressurization. However, it is very easy to occur that the gaps cannot be fully filled, and the leakage channels still exist after filling the glue solution; and a large amount of glue solution is coated on the surface of the inlay ring after filling, and a large amount of manpower is required to remove the surface glue solution, resulting in high labor costs and waste of glue solution.
