The utility model discloses an alumina material cut-off gate valve device, which belongs to the technical field of gate valves and comprises a cut-off pipe, a manual gate valve and a pneumatic gate valve, the cut-off pipe is arranged in the middle of an alumina material pipe, and two ends of the cut-off pipe are respectively connected with the manual gate valve and the pneumatic gate valve. The cut-off pipe, the manual gate valve and the pneumatic gate valve are all coaxially arranged with the aluminum oxide material pipe, and reinforcing plates are respectively arranged in the manual gate valve and the pneumatic gate valve. The device has the advantages that the manual gate valve is matched with the pneumatic gate valve, an aluminum oxide material pipeline can be cut off before overhaul, aluminum oxide materials are completely cut off, the situations of material leakage and the like are avoided, meanwhile, due to the arrangement of the two gate valves, one gate valve can be used as a main cut-off mode, the o
