Mechanical seal device

The utility model provides a mechanical seal device includes: axle sleeve, axle sleeve set up in the circumference outside of pivot to rotate along with the pivot is synchronous, the rotating ring, the fixed setting of rotating ring is rotated on the axle sleeve and with the axle sleeve is synchronous, quiet ring, quiet ring axial displaceable are moved to another place and are set up the circumference outside in the axle sleeve, and quiet ring has first end and second end, and the first end and the rotating ring looks butt of quiet ring coordinate, the flange, the fixed circumference outside that sets up at the axle sleeve of flange, elastic component, elastic component are located between the second end of flange and quiet ring, and the elastic component adds the axial force towards the rotating ring to quiet circulating application, the quiet ring structure of splining, quiet ring splines the structure setting between flange and quiet ring. The technical scheme of the utility model solve quiet ring sum rotating ring effectively and had the unbalanced pressure within a definite time, and leaded to the problem of the easy wearing and tearing of seal face of rotating ring and quiet interannular.
