The basic working principle of the gas water heater is that cold water enters the water heater and flows through the water-gas linkage valve body. Under the action of a certain pressure difference of the flowing water, the water-gas linkage valve is pushed and the DC power supply micro switch is pushed at the same time. Turn on the power and start the pulse igniter, and at the same time open the gas transmission solenoid valve, and continue to automatically re-ignite through the pulse igniter until the ignition succeeds and enters the normal working state. This process lasts for about 5 to 10 seconds. When the gas water heater encounters problems such as lack of water or insufficient water pressure, lack of electricity, lack of gas, excessive hot water temperature, accidental flameout, etc. during the working or ignition process, the pulse igniter will automatically cut off by detecting the signal fed back by the sensor needle. When the power supply and gas transmission solenoid valve are short of power supply, they immediately return to the original normally closed valve state, which means that the gas path has been cut off at this time, and the gas water heater is closed for safety protection.
