Title:
メカニカルシール装置
Document Type and Number:
Japanese Patent JP5039551
Kind Code:
B2
Abstract:
A mechanical seal device capable of preventing a sealing ability from being lowered by the irregular displacement of the seal surface of a sealing ring and by the deterioration of a packing for sealingly fitting the sealing ring by heat generated due to its slidable contact with the sealing ring. The mechanical seal device comprises the rubberlike elastic material annular packing having a joining face fitted peripheral surface (inner peripheral surface) of a stepped hole and an adhesive face on the inner peripheral side of the joining face and having an insertion tip part at its insertion tip inserted into the fitting peripheral surface and the sealing ring for fixing having a fitting surface joined to the adhesive face of the packing, a rear surface fitted to the support face (bottom face) of the stepped hole, and a seal surface on the opposite side of the rear surface. With the rear surface joined to a support surface, a space part is formed between the insertion tip part and the opposite surface thereto on the support surface side. The packing is inserted into the space part to fit the rear surface onto the support face by the elastic force of the packing.
