The invention discloses an electric high-temperature and high-pressure water-cooled regulation butterfly valve, and belongs to the technical field of design of water-cooled butterfly valves. The electric high-temperature and high-pressure water-cooled regulation butterfly valve comprises a valve clack, valve bodies, valve clack shafts, a rotation mechanism and a position display mechanism. Cooling water passageways formed by spiral round steel are arranged in the valve clack and valve body water jackets. The valve clack shafts include the first valve clack shaft and the second valve clack shaft. The valve clack is connected with the position display mechanism through the first valve clack shaft. The valve clack is connected with the rotation mechanism through the second valve clack shaft. Regulation and rotation of the valve clack are remotely controlled by an electric actuation barrel. The rotation angle of the butterfly valve is converted into an electric pulse through a rotation encoder and is output in the form of a digital quantity, and therefore precise control over the opening degree of the butterfly valve is achieved. The water-cooled butterfly valve can adapt to regulation of high-temperature and high-pressure gas pipelines in the industry; meanwhile, remote electric control can be achieved, and the electric high-temperature and high-pressure water-cooled regulation butterfly valve is safe, reliable and high in precision; and when the butterfly valve breaks down, troubleshooting, maintenance and replacement can be conveniently and rapidly conducted through the electric actuation barrel and the rotation encoder, cost is low, the electric high-temperature and high-pressure water-cooled regulation butterfly valve is convenient to use and saves time, and experiments are not influenced.
