description The utility model discloses an air bag type ceramic butterfly valve which comprises a base, an O-shaped ring, a lower valve shaft, a valve body, a ball, an air bag valve seat, a first pressing ring, a valve element, a pin, a second pressing ring, a valve seat sealing ring, a screw, a valve rod, padding, a pressing plate, a worm gear case, an air bag sealing ring and an inflation hole. After the air bag valve seat is inflated after the valve plate is closed, the air bag sealing ring is in contact with the valve seat sealing ring due to air pressure, and the valve is sealed; when the valve is opened, the air pressure of the air bag valve seat is firstly released, the air bag sealing ring is separated from the ceramic sealing surface of the valve seat sealing ring, then the valve plate is opened, and the valve plate does not generate friction with the sealing ring when being opened, so that abrasion is prevented, and friction sparks are eliminated; as the valve seat sealing ring is made of structural ceramics, t
