PROBLEM TO BE SOLVED: To solve the problem in which, in a conventional fire power adjusting device, it is necessary that an opening/closing valve is provided besides a solenoid safety valve; however, this opening/closing valve further requires a mechanism for driving a valve body, that is a motor and a solenoid coil, so that space occupied by the fire power adjusting device and the opening/closing valve becomes wider and cost of the opening/closing valve becomes high.SOLUTION: In a fire power adjusting device in which a solenoid safety valve whose valve body is adsorbed and held by an electromagnet and a fire power adjusting part for increasing/decreasing a flow rate are incorporated in series, which forcibly opens the solenoid safety valve by one motor and which adjusts a flow rate of gas passing through the fire power adjusting part by increasing/decreasing aperture of the fire power adjusting part, the opening/closing valve is incorporated in series with respect to the fire power adjusting part, and the opening/closing of the opening/closing valve is performed by the motor by interlocking the aperture of the fire power adjusting part and the opening/closing of the solenoid safety valve. |
