Casing pressure grinding device of sealing ring with positive conical surface

摘要: A casing pressure grinding device of a sealing ring with the positive conical surface comprises an internal inserting structure and external sleeving which can be matched in holding mode connected fastened through connecting structure. The is axial externally-convex table provided on radial side one end outwards-extending structural body taking central axis as rotation center. same direction working capable making contact non-sealing ring. other standard perpendicular to axis, internally-concave hole being mode, angle equal or larger than that surface. peripheral cylindrical diameter suitable for machined According surface, only has about several points dozens points, microns largest cutting quantity direction, very high quality demand over face specially positive-cone-shaped conveniently accurately face.
