Abstract
The utility model discloses a mechanical seal washer which comprises a silica gel ring and a hard alloy frame, wherein a clamping groove is installed on the outer surface of the silica gel ring along the surrounding direction, the hard alloy frame is located inside the clamping groove, and the upper surface and the lower surface of the silica gel ring are provided with annular grooves. Compared with an existing seal gasket, the mechanical seal washer utilizes the hard alloy frame to enhance hardness and avoid excessive deformation, provides a releasing space for compression deformation of a rubber body through installation of the annular grooves, prevents the rubber body from being damaged, and improves sealing effect.
Description
Technical field
