High-temperature molten salt butterfly valve

The utility model provides a high-temperature molten salt butterfly valve. The high-temperature molten salt butterfly valve comprises a valve body, a first baffle is movably connected into the valve body in a sleeved mode, a threaded rod is movably connected to the top of the first baffle in a sleeved mode, a pipeline is fixedly connected to the side face of the valve body in a sleeved mode, an adjusting box is fixedly connected to the top of the valve body, and a first gear is movably connected into the adjusting box in a sleeved mode. According to the high-temperature molten salt butterfly valve, by arranging the first gear, when the butterfly valve needs to be opened and closed, the rotating motor is started to drive the first gear to rotate through the second gear, namely, the threaded rod is driven to move up and down, and the threaded rod drives the first baffle to move up and down; therefore, the opening and closing effect of the interior of the valve body is achieved, the problem that long-time operat
