The invention discloses a gate valve capable of being remotely controlled and relates to the technical field of gate valves. The gate valve comprises a valve body and a valve deck. The valve body andthe valve deck are fixedly connected through first screws and first nuts. The center of the valve deck is rotationally connected with a valve rod. One end of the valve rod is fixedly connected with awedge disc through a fixing block. The top of the valve deck is fixedly connected with a fixing cover. One side of the inner wall of the fixing cover is fixedly connected with a motor. The inner wallof the fixing cover is horizontally and fixedly connected with a supporting plate. One side of the top of the supporting plate is fixedly connected with a communicating device. The side, away from thecommunicating device, of the top of the supporting plate is fixedly connected with a rectifier. By means of the gate valve capable of being remotely controlled, the problems that the mounting positions of certain gate valves are remote, workers need to walk to the gate valves to operate the gate valves when the gate valves need to be operated, the timeliness is poor, shuttling back and forth needs to consume a long time, in addition, manpower manual operation is needed when existing gate valves are opened and closed, and time and force are consumed are solved.
