The invention discloses an electronic control variable-pressure gas overflow valve. The electronic control variable-pressure gas overflow valve is arranged in a shell of which the pressure is to be regulated, and comprises a valve seat, a metal valve plate and a rolling diaphragm, wherein the valve seat is hermetically and fixedly connected with the shell; the rolling diaphragm is arranged in a step hole in the shell; the metal valve plate is arranged on the rolling diaphragm; an excitation mechanism is arranged at the bottom of a sealed structure, and is connected with an external current controller; the excitation mechanism generates magnetic force under the control of the current controller, and attracts the metal valve plate, so that the valve seat is pressed by the metal valve plate; the sealed structure is formed in an inner cavity of the shell; when the acting force of gas in the shell on the metal valve plate exceeds the magnetic force of excitation exciting mechanism, the sealed structure is opened, and the gas is discharged from an air-bleed hole in the shell.
