特徴とする螺形弁。In a spiral valve, a valve body supported and fixed to a lifting rod rotates to open and close within a flow hole of an elastic annular seat ring built into the valve body. A stepped portion is provided on the side surface following the provided annular recess, and an extension portion thinner than the ear portion formed integrally with the side surface of the ear portion of the elastic annular seat ring that fits into the annular recess. and to fit it into the step part, and to completely absorb the movement of the ear part that fits into the annular recess part due to the pressure of the flange during piping. A spiral valve characterized by having a corresponding gap between the two parts.
