弁を同一軸心上の主弁軸および副弁軸とでそれぞ
れの弁を回動し開閉できるように枢支して構成す
る副弁内蔵式蝶弁形において、上記副弁軸を前記
副弁の取付孔に対して進退自在にスプライン結合
するとともに、位置固定ネジを該副弁表面から前
記スプライン結合部まで延出して該副弁軸を前記
副弁に固定接続して構成したことを特徴とする副
弁内蔵式蝶形弁における副弁構造。 A sub valve is fitted in the center of the main valve, and both main and sub valves are pivoted to the main valve shaft and the sub valve shaft on the same axis so that each valve can be rotated to open and close. In the butterfly valve type with a built-in valve, the sub-valve shaft is spline-coupled to the mounting hole of the sub-valve so as to be movable forward and backward, and a position fixing screw is extended from the surface of the sub-valve to the spline joint portion to connect the sub-valve. A sub-valve structure in a butterfly valve with a built-in sub-valve, characterized in that a shaft is fixedly connected to the sub-valve.
