用シール弁。In a valve that opens and closes a valve plate whose lower surface is made of a spherical surface by moving along an arc of a substantially spherical surface, a tube seal made of a hollow elastic body is disposed adjacent to the entire circumference of the lower surface of the valve plate. After the plate moves to the closed position, fluid is injected into the inner cavity of the tube seal to inflate the tube seal, bringing the lower part of the valve plate into close contact with the tube seal, sealing off the high pressure gas in the valve chamber, and sealing the tube. A seal valve for a blast furnace, characterized in that the valve is opened after contracting the tube seal and releasing the close contact between the lower part of the valve plate and the tube seal by releasing fluid press-fitted into the internal cavity of the seal.
