Abstract
The invention provides an adjustable fuel gas valve capable of being turned on and off and ignited synchronously. The adjustable fuel gas valve comprises a valve body, a valve deck, a valve element, a valve rod, a valve rod spring, an electromagnetic valve, a micro-switch, a pressing plate and a transmission part, and further comprises a centre and a valve bottom cover. The transmission part comprises a rotating shaft, an angular drive rod and a transmission foot. The valve bottom cover and the lower end of the valve body are fixedly connected through a screw. A shaft base is arranged in a cavity of the valve bottom cover. A rotating shaft of the transmission part is matched with the shaft base in a rotating mode. The angular drive rod is matched with a valve element body of the electromagnetic valve. The centre penetrates through the valve rod spring and a guide hole in a partition board and extends out of the valve element cavity. The lower end of the centre is arranged in the bottom cavity. The upper portion of the centre is arranged in a counter bore. The centre and the guide hole are matched in a sliding mode and sealed in an air mode. The lower end of the centre is matched with the transmission foot of the transmission part. Due to the structure, a valve rod directly drives an ejector rod driving a transmission rod; when a burner catches a fire accidentally, a thermo-coupler does not generate thermoelectricity, the electromagnetic valve is turned off, fuel gas is cut off and does not pass through the valve element so that the fuel gas can be prevented from being output, and the potential safety hazard is eliminated.
