Gas supply circuit
Working principles
When the machine is connected to the gas supply, the gas passes in sequence the
following parts: 1. Gas inlet 2. Flameout protector 3. Electromagnetic valve 4. Gas
rate adjustment valve 5. Gas nozzle 6. Being ignited by the high-voltage spark plug
and burning at the burning head 7. Current occurs in the thermocouple due to the
heat output by gas burning. 8. The thermostat activates an electric circuit to enable
the small electromagnetic valve in the flameout protector magnetizing the armature
of flameout protection valve, the gas passes through and burns continuously.
