Claims (1)
弁本体に回動自在に取着した弁軸に固着“ した弁板
を前記シートリング内側において回動開閉させるように
したものにおいて、 前記弁軸を弁板に取着した位置における弁板外面に形成
した１次シール用の円形平坦部に少なくとも１個の円形
溝を夫々形成するとともに、弁外から前記円形溝に潤滑
剤を圧封入してなる中心型ちょう形弁のシール機構。[Claims for Utility Model Registration] An elastic seat ring is stretched around the inner peripheral surface of an annular valve body, and a valve plate fixed to a valve shaft rotatably attached to the valve body is rotated inside the seat ring. In a device configured to be opened and closed dynamically, at least one circular groove is formed in each of the circular flat portions for a primary seal formed on the outer surface of the valve plate at the position where the valve stem is attached to the valve plate, and A sealing mechanism for a central butterfly valve in which a lubricant is pressure-sealed into the circular groove.
