As society evolves, most urban households use gas heaters. It is easy and fast to provide hot water at all times, and even in the winter it can be comfortable to bathe at home, wash its faces, wash its vegetables, cook, etc. And we all know that the electromagnetic valve is one of the most important components of the gas heater. The electromagnetic valves of the gas heater are mainly used to control the combustion of the gas heater. So what's the working method of the heater's electromagnetic valve? And what's the main effect? Let's look at them together。
Activation of electromagnetic valves for gas heaters
First, when cold water enters the water heater, it passes through the hydrogas conjunction valve, which, with some pressure from the water flow, pushes the hydraulic conjunction valve, the door, and the micromovement switch, and connects the power to the pulse controller. At this point, the gas electromagnetic valve is opened and the gas heater's burner is lit. When the burner ignites, the flame detection element detects the flame signal and transmits it to the pulse controller, which opens the electromagnetic valves by maintaining currents and maintaining normal combustion of the burner。
If the burner does not ignite successfully, then the pulse controller cannot receive the fire signal, so that the normal opening of the electromagnetic valve cannot be guaranteed by maintaining current currents。
The role of an electromagnetic valve for gas heaters
1. Emps primarily act as hydrogas connections. In accordance with normal start-up procedures, first water access, then micro-activated switches are activated by book adoption, so that power is connected; and then, about three seconds later, the electromagnetic valve began to inhale, so that it could burn. It's simple to understand, it's water, electricity, finally air. In the absence of an electromagnetic valve, direct ventilation occurs when the water goes through, so that if the ignition is delayed, the gas will be filled with the entire combustion chamber, and a single fire will explode, with serious consequences。
2. The water heater electromagnetic valves perform a dual protection function. When cold water enters the water heater, the water membrane is subject to water pressure, and it turns the whole machine on, and it pushs the spring top to the left, which is the switch to another control source. It is therefore likely that the membrane will not be able to return to its original position when the water membrane has been used for a long period of time, resulting in sludge and sludge, so that the gas switch will not be turned off. If there were no electromagnetic valves at that time, the switch would remain open, the gas would leak and safety risks would be buried。
Common malfunctions and maintenance techniques
Burning out means that a firearm can work normally. This phenomenon is linked to energy-saving design for firearms. Those who have studied electric science will know that when electromagnetics start, they need larger currents, and when they do, they need smaller maintenance. Firearm controls the opening of the electromagnetic valves, which also have two working circles. It's usually the two circuits that run out of electricity at the time of start-up, so that the electromagnetic valves can be opened, so that they don't need this much power, and they turn off the circuit known as start-up. When the current is activated, it is usually larger and the electromagnetic valve can be activated on its own。
It's a problem to keep the current going. The maintenance of circuits is either too low for battery voltage, or there is a problem with shooting firearms. This failure often occurs in a number of resistant gas water heaters on the market. If you have the skills to maintain electrical appliances, you can also repair firearms yourself。
If you touch the water, burn normal, fire the light, light the fire, but the fire continues, then the fire stops in about 10 seconds, and it stops burning. The fire detection circuits for firearms are generally problematic, mostly because of poor contact between the probe and the guide. In order to prevent the gas from entering the burner without a fire spill causing a hazard, there was a combustion detection probe beside the burner, in addition to two shots. The probe is not made of special materials, but uses flames to connect to the burner, disrupts the conditions for the internal high pressure oscillator of the fire, stops the fire and saves energy, while keeping the electric magnetic valve open. If there is no fire, the internal oscillator is timed to stop firing and the electromagnetic valves are shut down。
The above is a detailed analysis of the working principles and functions of the water heater's electromagnetic valves, which is believed to be of some help in making better use of gas heaters. Gas heaters are very easy to use, and their electromagnetic valves are more rationally designed to ensure safety in our use. However, in the event of a failure of an electromagnetic valve, it is important that specialized maintenance staff be identified and engaged in repair or replacement in a timely manner to avoid hazards。
