ニカルシール。 A non-rotating seal ring axially biased by a spring slides closely against a rotating mating ring supported by a flange of a sleeve mounted on the shaft, sealing the fluid on the outer diameter side of its sliding surface. In the internal flow type mechanical seal, the flange is
an outer flange portion that bends and extends from the sleeve toward the outer diameter side; and an inner flange portion that extends toward the inner diameter side with an appropriate gap between the inner surface of the outer flange portion that is folded inward from the outer diameter end of the outer flange portion; An internal flow type mechanical seal characterized in that a mating ring is tightly fitted into the inner flange.
