Claims

[Scope of Claim for Utility Model Registration] A conduit section consisting of a piping pipe in which a shaft hole through which a valve stem is inserted is formed at diametrically opposed positions, and a hole in the conduit section that is aligned with the position of the hole through which the valve stem is inserted. two bearing blocks that abut and are fastened to each other while sealing on both opposing outer peripheral surfaces, and a disc-shaped valve body that is placed within the conduit section and opens and closes the flow path by coming into contact with and separating from the inner circumferential surface of the conduit section. and a valve stem that pivotally supports the valve body, wherein both ends of the valve stem extend outward from the conduit section and are pivotally supported by the bearing block.
