Stop valve

The utility model discloses a stop valve. The stop valve comprises a valve body, an electric control assembly, a flow sensing assembly, a man-machine interaction module and a control module. A water passage is arranged in the valve body; the electric control assembly is used for opening or closing the water passage; the flow sensing assembly is located on the downstream of the electric control assembly and used for forming a sensing signal based on flowing water flow. The man-machine interaction module is used for receiving user operation to obtain and send target flow information and target time information; and the control module is electrically connected with the electric control assembly and the man-machine interaction module, is in signal connection with the flow sensing assembly, receives and stores the target flow information and the target time information, further receives the sensing signal, forms the accumulated water flow and the accumulated water time of the water passage, and controls the operat
