とを特徴とする溶鉱炉の原料投入口用の開閉弁。A blast furnace is provided with a valve seat around a raw material inlet opened in an inclined manner inside the furnace top of the blast furnace, and a swing valve body that can swing freely is pressed against the valve seat to close the raw material inlet. In the on-off valve for the raw material input port, an arc-shaped groove is formed on the lower side of the swing valve body facing the raw material input port, and an arc-shaped water storage plate is protruded from the groove from the bottom of the groove. What is claimed is: 1. An on-off valve for a raw material input port of a blast furnace, characterized in that the valve is installed upright and has an arc-shaped introduction plate positioned inside and fixed to a water storage plate around the lower side of the raw material input port.
