Household gas electromagnetic How to reset the valve

Many industries that require gas heating automatic control systems will use gas solenoid valves, whose main function is to automatically control the temperature. How to reset the household gas solenoid valve? What are the advantages of using natural gas?

First, you need to check the gas to make sure there is no gas leakage problem, and then disconnect thesolenoid valve power supply, and finally lift up the dust cover on the solenoid valve, and the solenoid valve is reset. Be careful when lifting the dust cover to avoid damaging the dust cover.

The role of household gas solenoid valve

The solenoid valve mainly plays the role of water-gas linkage. According to the normal starting procedure, first turn on the water, and the micro switch will be activated when the book passes, so that the power can be turned on;then ignite, and in about 3 seconds, the solenoid valve will start to close, so that ventilation and combustion can begin. To put it simply, the water is supplied first, then the electricity is supplied, and finally the ventilation is supplied. If notSolenoid valve, then it will ventilate directly when the water is passed, so that if the ignition is delayed, the gas will fill the entire combustion chamber, If it catches fire, it will explode and the consequences will be very serious.

Working principle of household gas solenoid valve

First of all, when cold water enters the water heater, it will go through the water-gas linkage The valve body, under a certain pressure of the water flow, can push the water-gas linkage valve and the micro switch to turn on the power, and at the same time start the pulse controller. At this time, open the gas solenoid valve and the burner of the gas water heater is ignited. After the burner is ignited, the flame detection element will detect the flame signal and then transmit it to the pulse controller. The pulse controller will open the solenoid valve by maintaining the current and maintain normal combustion of the burner.

If the burner does not ignite successfully, the pulse controller will not receive the flame signal, so it will not be able to maintain the current flow to ensure the normal opening of the solenoid valve.
