Claims

[Claims for Utility Model Registration] (1) A body, a cap fastened to the body, a valve body housed within the body and rotated to open, close, or adjust fluid flow; A rotary valve consisting of an annular plate-shaped seat ring which is sandwiched between the valve body and the inner periphery of which is in sealing contact with the valve body, and the seat ring is directly sandwiched between the body and the inner edge of the cap. A rotary valve featuring (2) A gasket that simultaneously seals between the body or the cap and the seat ring and between the body and the cap is housed outward from the inner edge of the body or the cap that sandwiches the seat ring. 2. The rotary valve according to claim 1, further comprising an annular stepped portion. (3) An annular stepped portion for accommodating a gasket for sealing between the body or the cap and the seat ring is provided outward from the inner edge of the body or the cap that sandwiches the seat ring, and further outward. 2. A rotary valve according to claim 1, further comprising an annular step for accommodating a gasket sealing between said body and said cap. (4) The gasket that seals between the body and the cap has a cross-sectional shape such as a U-shape, a U-shape, or a V-shape so that the sealing performance is improved by the pressure of the fluid. rotary valve. (5) The rotary valve according to any one of claims 1 to 4, further comprising a shim for adjusting the relative position between the seat ring and the valve body between the inner edge portion of the body that clamps the seat ring and the seat ring. (6) The rotary valve according to any one of claims 1 to 5, wherein the seat ring comprises a holder portion held between the body and the cap, and a seat portion in sealing contact with the valve body.
