Claims

[Scope of utility model registration request]

(1) A deep widening groove is formed in at least one of the peripheral edge of the valve body or the inner circumferential surface of the valve body, and an elastic sheet having a space formed along the entire length in the longitudinal direction is fitted into the deep widening groove, and the elastic sheet The seat mounting structure of the butterfly valve is constructed by inserting a hard core material into the space of the elastic sheet to press the elastic sheet against the groove wall of the deep widening groove and prevent the elastic sheet from being pulled out from the deep widening groove. A structure for attaching a seat to a butterfly valve, characterized in that a hard member that contacts the hard core material is provided in the space of the elastic sheet.

(2) The width of the elastic sheet is approximately the same over the entire length, and when the core material is being inserted into the space, the width is wider on the side where the core material is inserted into the space, and the width is wider on the side where the hard core material is inserted into the space. The seat installation described in claim (1) of the utility model registration, which is between the middle and the middle, is a structure.
