る軸封機構。[Claims for Utility Model Registration] An elastic seat ring is stretched around the inner peripheral surface of the annular valve body, and a through hole formed in a diametrically opposed position of the seat ring is passed through, and the valve shaft to which the valve plate is fixed is inserted into the valve body. In a butterfly valve that is pivotally attached to the main body, an annular protrusion is formed on the inner circumferential surface of the through hole of the seat ring to press against the outer circumferential surface of the valve stem and perform a sealing action when the valve stem is inserted. A backup ring is disposed on the outer edge of the through hole of the IJ song, and is rotatable around the valve shaft and has an annular falling part that reaches a protrusion on the circumferential surface of the IJ song. Shaft sealing mechanism.
