カニカルシール。A floating seat is supported on a mounting part such as a flange fixed to the end of the housing into which the rotating shaft is inserted, and a seal ring provided on the rotating shaft side is appropriately elastically biased to press and slide into contact with the floating seat. In this mechanical seal, the outer diameter portion and inner diameter portion of the floating seat, which have different seal diameters, are airtightly supported with respect to the flange side mounting portion through sealing members such as O-rings, and A part of the sealing fluid to be pressurized and fed into the cavity is introduced between both the seal members and the flange mounting portion on the rear end surface of the floating seat, and the pressure contact force on the flange mounting surface of the rear end surface of the floating seat is reduced. A mechanical seal characterized by reducing the amount of water.
