PURPOSE: A disc valve for the cut-off of a turbo charger of a large-sized engine for a ship is provided to open a disc after soot attached on the surface of the disc is removed and to cut off the flow of exhaust gas. CONSTITUTION: A disc valve for the cut-off of a turbo charger of a large-sized engine for a ship comprises a valve body(10), first and second high-pressure air supply pipes(30), valves(50), a high-pressure air and soot discharge pipe, and a high-pressure diffusing member(40). The first and second high-pressure air supply pipes are inserted into first and second holes of the valve body. The high-pressure air and soot discharge pipe is inserted into a third hole of the valve body. The valves are respectively assembled in the first and second high-pressure air supply pipes and the high-pressure air and soot discharge pipe and supply or cut off high-pressure air. The high-pressure diffusing member diffuses the high-pressure air flowing into the valve body in all directions.
