The invention relates to a control circuit for controlling the shutoff of fuel gas supply of a solenoid valve in emergency situation. The invention solves the problem that the fuel gas supply solenoidvalve cannot be automatically shut off when a direct-current power supply stops power supply after the commercial power fails on the premise of not needing to consume additional electrical energy fora long time. The invention provides the fuel gas shutoff solenoid valve controller, which is connected with a capacitor (C), wherein the capacitor (C) forms a charging circuit with the direct-currentpower supply (VDC) on one hand, and forms a discharging circuit with the solenoid valve (L) on the other hand; and a coil (J1) of a relay is connected with a power supply terminal, so that the switching between the charging circuit and the discharging circuit can be performed according to the power supply/power failure stage of the direct-current power supply (VDC).
