Abstract

PURPOSE:To prevent oil leak and excessive abrasion by superposing the cylindrical sealing rings in concentric form and floating-holding said sealing rings by an O-ring and a snap ring in the cylinder part of a gland cover inserted into a stuffing box. CONSTITUTION:A gland cover 2 is installed onto the rear edge surface of a stuffing box 1 through a gasket 15, and inserted into the stuffing box 1 through an O-ring 14, having the outer peripheral surface of a cylindrical part 9 as fitting part. In the cylinder part 9, the cylindrical sheet ring 5 made of hard material are superposed in concentric circular form through an O-ring 12, having the rear edge surfaces as fitting surface, and floating held onto the front edge part by fitting a snap ring 10 for restricting the shift to the atmosphere side, and turn is suppressed by a pin 11. The sheet ring 5 is pressed by a trailing ring 7 having a spring 8 and an O-ring 13 interposed, by a stopper 6 fixed onto a rotary shaft 3. Therefore, the generation of excessive abrasion and seizure is prevented, and the leak on sealed edge surface can be prevented.
