Claims

[Scope of Claim for Utility Model Registration] (1) A valve seat structure in a valve in which a valve seat is provided in a valve port provided in a passage from an inlet to an outlet so that the valve seat can be opened and closed, and the valve seat is located on the side of the valve case body. A separate valve seat body formed in the shape of a cylindrical ring is press-fitted into the seat fitting portion, and an arc-shaped valve seat portion with an edge curved outward or inward is attached to the upper end of the cylindrical ring of the valve seat body. A valve seat structure characterized by being formed. (2) The valve seat structure according to claim 1, wherein the outer diameter of the cylindrical portion of the valve seat body is formed to be slightly larger than the inner diameter of the valve seat fitting portion on the main body side, and is defined to have a size with a press-fitting allowance. (3) The valve seat structure according to any one of claims 1 to 2, wherein the fitting position of the valve seat body with respect to the valve seat fitting portion is variably set up and down.
