The invention relates to an intelligent safety valve. Traditional safety valves usually adopt traditional driving methods to detect water flow and control valve closing, for example, an American invention US 2012/0153195, the traditional methods are prone to resulting in impact between a piston head and a passage, and wear of the piston head and the passage is prone to occurring and leading to deterioration of a safety factor when the time of use becomes longer. In addition, reset is realized by the contact between a reset button and a piston, but the direct contact method is prone to resulting in wear and seizure and a decrease in the stability of a safety valve structure. In view of the above shortcomings, the intelligent safety valve is provided, the intelligent safety valve comprises ashell and a reset button, wherein a water inlet is formed in one end of the shell, the water inlet communicates with a water inlet channel, a water outlet is formed in the other end of the shell, andthe water outlet communicates with a water outlet channel; the reset button is arranged on one side of the shell and is used for resetting the safety valve; and an impeller is arranged in the water inlet channel and rotates coaxially with a first helical gear arranged outside the water inlet channel.
