ト部構造。 An eccentric butterfly valve seat structure in which either the valve body 1 or the valve body 4 is provided with an annular metal sheet 11 for sealing between the two,
When the annular metal sheet 11 is closed, the outer circumference 11A of the annular metal sheet 11 becomes the inner circumference 11B.
A concave groove 12 formed in the shape of a disc spring that is deflected and deformed so as to be relatively displaced in the axial direction relative to the valve body 1 or the valve body 4, and into which the annular metal sheet 11 is fitted and held is formed into a concave groove 12. A seat part structure of an eccentric butterfly valve, which is formed on the circumference of the eccentric butterfly valve, and the annular metal sheet 11 is loosely fitted into the recessed groove 12.
