トリング抜き治具。 The seat ring removal jig is used to remove the seat ring of a mechanical seal installed in the shaft hole of the equipment housing to the outside of the machine.The seat ring is divided by a notch that extends in the axial direction at the front and tapers inwardly. It has a cylindrical body having a plurality of divided pieces each having an outer diameter protrusion formed at the tip thereof, a female screw threaded at least at the rear of the inner circumferential surface, and a handle on the outer diameter of the rear end. A member is fixedly installed, and a male thread that engages with the female thread is screwed on at least the rear part of the outer circumferential surface, and the inner cylinder is inserted into the body so as to be able to move back and forth in the axial direction. A seat ring removal jig, characterized in that the split piece is flexibly deformed to expand and contract its diameter by the tip of the inner cylinder that slides in the axial and circumferential directions while coming into contact with the tapered inner peripheral surface of the split piece.
