Gas circuit switching device for digital display module of oil-gas sliding casting disc

The utility model relates to a digital display module gas path switching device for an oil-gas sliding casting disc, which effectively solves the problem that specific gas path information on each crystallizer cannot be displayed. Comprising a body fixed to a casting disc, a plurality of first gas paths communicated with a crystallizer are arranged in the body, adjusting valves are arranged on the first gas paths, the first gas paths are provided with second gas paths in parallel, the second gas paths are connected with the same display module, the connecting points of the second gas paths and the first gas paths are located behind the adjusting valves, and gas valves are arranged on the second gas paths; the device is simple and ingenious in structure and convenient to use, gas path information on the corresponding crystallizer is displayed on the display module, each gas path can be conveniently adjusted and controlled, communication between the gas paths and the display module is cut off in a non-adjusting
