Abstract

The invention discloses a water-cooled shut-off valve installed on a flue gas pipeline, comprising a valve body, the valve body is provided with a valve cavity, the bottom of the valve cavity is provided with an air inlet, and the side wall of the valve cavity is provided with There is an exhaust port, a valve core is arranged in the valve cavity, and the valve core is driven to rise and fall in the valve cavity by a lifting drive mechanism. When the valve core is lowered to the lowest position, the valve core and the air inlet The valve core is provided with a cooling cavity, and the cooling cavity is connected with a circulating water inlet and a circulating water outlet. The valve is simple in structure, has the function of water cooling and self-cooling, is not easily deformed in a high temperature environment, has good sealing effect and reliable operation, and belongs to the field of smelting.

Description

technical field [0001] The invention belongs to the field of smelting, and more particularly relates to a water-cooled shut-off valve installed on a flue gas pipeline. Background technique [0002] The temperature of smelting flue gas is generally above 500-1000 ℃, and some are even higher than 1000 ℃, and the diameter of the flue gas pipeline is very large, often one or two meters, which requires a very large shut-off valve, and these shut-off valves are used in high temperature conditions. After a period of time, the problem of valve core deformation is likely to occur, and it is difficult to solve the problem of flue gas leakage caused by valve core deformation in the prior art. [0003] CN200820227778.6 discloses an aluminum smelting furnace flue gas channel valve, which consists of a support frame located outside the aluminum smelting furnace flue gas channel, a high-temperature buffer cylinder, a sprocket on the support frame, a connecting rod, and a connecting rod and...
