The basic working principle of gas water heaters

The basic principle of APG gas heater is cold water into the food, water and gas flowing through the joint body under a certain pressure difference between the effect of the flow of water, promote water-gas linkage valves, and a DC power supply while promoting micro switch will power on and start pulse ignition, at the same time open the gas gas solenoid valve, pulse igniter continue through automatic re-ignition until the ignition success so far into the normal working state, this process continuously maintain about 5 to 10 seconds, when a gas water heater in the course of their work or ignition occurs or insufficient water pressure, lack of electricity, lack of gas, hot water temperature is too high, unexpected blow when flameout and other symptoms, pulse igniter feedback signal by detecting the sensor needle, automatically cut off power, gas gas solenoid the case of lack of electricity supply valve immediately reply to the original normally closed valve state, that this time has been cut off the gas passage, shut off the gas heater play a security role. Typically a qualified gas water heater, refers to the performance indicators in line with GB6932-2001 (home gas heaters) Gas Water Heater national standards, from the ignition state to enter the normal operating state of the entire process is fully automated control, without manual adjustments or additional Setting, simply open the cold water switch or turn cold water, and air conditioning apparatus adjustment means getting the right amount of water and the water temperature by adjusting the amount of water, gas water heater immediately within 5 to 10 seconds in a short time into the normal working state, while output hot water, once more unexpected failure, gas water heater will automatically stop working within 10 seconds, and immediately cut off the gas passage to prevent the gas continues to flow, and can not be automatically re-opened, unless artificially clear the fault and restart the gas water heater , in order to work state, so its performance is more secure and reliable
