The valve body is welded by steel plates and forging flanges. The valve disc of the existing butterfly valve is set on the valve stem, and the valve stem is driven by an electric device or manually. When it is used in the energy flue gas recovery system of the catalytic cracking unit, the service life is relatively short when it is used under high-temperature conditions of 680℃-1100℃. Therefore, it is necessary to dissipate heat from the valve during use to avoid excessive temperature of the valve affecting the normal use of the valve.
