A butterfly valve portion having an outer shape substantially the same as the cross-sectional shape of the flow path is swingably provided in the flow path via a swing shaft, and a discharge pipe communicating with the discharge port is connected to the flow path. A valve seat is formed at the opening end by protruding into the passage, and when the butterfly valve part opens the flow passage by swinging the swing shaft in one direction, the side seal of the butterfly valve part closes the discharge pipe. The opening end closes when it comes into contact with the valve seat of the butterfly valve, and the flow path is partially opened or fully closed by swinging in the other direction, and the opening end of the discharge pipe is opened. A butterfly valve characterized by:
