                 Gas Stove Pulse Ignition Working Principle (with electric thermocouple, no electric thermocouple)

Open the gas valve, press the knob, the knob bar down to promote the body with the thimble down to move the thimble to push the valve body crank swing to promote the solenoid valve open; At the same time, the knob on the metal sheet with pulse ignition The switch lever is in the keyway of the valve spool. If the knob rotates counterclockwise (clockwise), the valve will rotate in a clockwise direction. Positioning device limit, can not turn), the knob position of the top stall will spin to the step table, from the valve body positioning restrictions, the valve core will rotate along with the knob, the valve spool and the valve body The air holes are aligned and connected. At this point the gas will be through the gas pipe → → → body valve body valve valve → solenoid valve → nozzle → nozzle (mixed with the air) → burner → damper → fire cover (air mixed with the second), the case of After the fire burning. By adjusting the size of the damper (change the air flow cross-section) can change the primary air mixing coefficient, affecting the flame combustion conditions, to prevent the production of yellow flame. As the beginning of combustion, the thermocouple will produce electromotive heat, through the wire into the solenoid valve coil, resulting in a magnetic field so that the solenoid valve to pull, thus maintaining the valve open, so the free hand to adjust the flame size. When the accidental flameout, the thermocouple terminal voltage quickly becomes zero, the solenoid valve coil loss, under the action of the spring, quickly cut off the gas pathway to prevent gas spill. If you want to turn off the gas stove, you can turn the knob clockwise to "off" position can be, this time, the valve spool and solenoid valve will cut off the gas path, the combustion stops, the gas does not spill; knob bar positioning gear swing to the positioning slot The knob can not be rotated.
