Water heater accessories liquefied gas water heater intake valve solenoid ZD131 3V valve.
With the continuous development of society, most urban households have used gas water heaters. It is convenient and fast, and can provide hot water at any time, even in winter, you can take a bath, wash your face, wash vegetables, cook, etc. comfortably at home even in winter. And we all know that in the gas water heater, the solenoid valve is its core component and one of the most important components. The solenoid valve of the gas water heater is mainly used to control the ignition of the gas water heater, so what is the working principle of the solenoid valve of the water heater? What are the main functions? Let's take a look.
The working principle of the solenoid valve of the gas water heater
First of all, when cold water enters the water heater, it will pass through the water-gas linkage valve body. Under the action of a certain pressure of the water flow, the water-gas linkage valve and the micro switch can be pushed to turn on the power, and the pulse controller will be activated at the same time. At this time, the gas solenoid valve is opened, 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 send it to the pulse controller. The pulse controller will open the solenoid valve by maintaining the current and maintain the normal combustion of the burner.
If the burner is not successfully ignited, the pulse controller will not receive the flame signal, so that the solenoid valve cannot be opened normally by maintaining the current.
The role of the solenoid valve of the gas water heater
1. The solenoid valve mainly plays the role of water and gas linkage. According to the normal start-up procedure, the micro switch will be activated when the water is passed first, and then the power will be turned on; then it will ignite, about 3 seconds, and the solenoid valve will start to attract, so that it can supply gas for burning. To understand it simply, it is to pass water first, then igniting, and finally supply gas. If there is no solenoid valve, the gas will be directly supplied when the water is passed. In this way, if the ignition is delayed, the gas will fill the entire combustion chamber, and an explosion will occur upon ignition. The consequences are very serious.
2.The solenoid valve of the water heater plays a double protective role. When the cold water enters the water heater, the water membrane is affected by the water pressure, which will turn on the power of the whole machine, and at the same time push the spring top cover to the left. This spring top cover is another switch for controlling the gas source. Therefore, when the water membrane produces scale and slag due to long-term use, it may not be able to return to the original position, so that the gas switch cannot be turned off. If there is no solenoid valve at this time, then the switch will always be on, gas leakage will occur, and there will be potential safety hazards.
