Gas water heaters are the most commonly used electrical products in our home. Speaking of gas water heaters, we cannot but mention the gas water heater solenoid valves . Do you not know how much you connect to it? Next we take a look at the specific introduction of the gas water heater solenoid valve .
Gas water heater solenoid valve structure
The gas water heater solenoid valve is mainly composed of a base, a fixed iron core, a coil, an armature, and a fixing member. The fixed iron core is set on the base, the coil is positioned on the fixed iron core, and the armature is supported on the fixed iron core, which is a movable connection. The fixing member is fixedly connected with the base and is located above the armature. Two clips extend from both sides of the fixing member, characterized in that the two clips further extend out of the extension portion in the required direction, and correspond to the extending portions of the armature and the two clips. Each point is set to maintain a small gap with the extension of the two clips, and the two pivots are basically concentric with the swing axis of the iron core.
Gas water heater solenoid valve works
The cold water enters the water heater and flows through the water and gas linkage valve body under a certain pressure difference value of the flowing water to push the water vapor linkage valve and push the micro switch to turn on the power and start the pulse controller, and turn on the gas water heater electromagnetic valve, The burner of the gas water heater is ignited; after the burner is ignited, the flame detection element gives a flame signal to the pulse controller by detecting the flame, and the solenoid valve is opened by maintaining the current to maintain the normal combustion of the burner.
If the ignition fails, the pulse igniter is unable to maintain the normal opening of the gas water heater solenoid valve due to no detection of the flame holding current signal, and the solenoid valve is closed to cut off the gas supply. The gas water heater can minimize the frictional resistance of the armature during movement so as to minimize the starting current and voltage, save electric energy and ensure sensitive operation. For the gas-fired water heater adopting the battery, and the self-power generation using the water flow as the power source Gas water heaters are suitable.
Gas water heater solenoid valve function and function
General gas water heater in accordance with the normal start-up procedure is: first through the water, and then start the micro switch, the whole power, and then ignition, in the 1-3 seconds after the ignition, the solenoid valve suction, ventilation, combustion. If the gas water heater solenoid valve is lost, it will be ventilated when the water is turned on. If the ignition is delayed and the gas fills the combustion chamber, deflagration will occur. What is said here is a water vapor linkage of the gas water heater solenoid valve.
The double protection of the gas water heater solenoid valve, that is, the water pressure is activated at the same time, the water film is affected by the water pressure, while pushing the left, at the same time, turned on the power of the whole machine, and also put a spring top cover, top to the left. (This is another switch that controls the air supply.) It is a mechanical action. If there is a dreg in the water film, if the water film does not reach the scale after the scale, if you do not use the gas water heater solenoid valve, it will leak. A safety incident occurred.
Solution of Gas Water Heater Solenoid Valve Fault
The solenoid valve of the gas water heater is actuated by the water pressure to activate the micro switch. The solenoid valve is opened and at the same time the fire is opened. In addition, the pressure regulating valve and the pipeline will not affect the intake air flow, which may cause the fire to burn abnormally. The water pressure is too small. The switch is not energized, and the reed switch can be adjusted so that it can be turned on under low water pressure. The airway is not unobstructed. Check the pressure regulator first and remove the obstruction.
Gas water heater solenoid valve does not work, first take a look at the battery is not to change, if it is a strong row may be the circuit board or solenoid valve is broken, and if it is liquefied gas, it is necessary to see if the pressure is too high Pull down the air pipe on the water heater to see if the solenoid valve has any sound. If there is air pressure, replace it with a decompression valve.
If it is installed battery, replace the battery just fine, strong drain power is the heater igniter is broken, the water pressure is low, increase the booster pump to clean the inlet pipe, remove the nozzle garbage solenoid valve body failure, replace the solenoid valve , Be sure to pay attention to professional maintenance.
Regarding the gas water heater solenoid valve , I will introduce it to you here. I hope I can help you. More information on the decoration is on this site. Please stay tuned.
Gas water heater
Knife Sharpener has stick shape,it is generally selected from medium carbon steel or high carbon steel with magnet .It is high hardness, more wear-resisting, uniform and fine serrated, with good effect of grinding knife. There are a variety of materials for knife sharpener,such as wooden handle,PP handle,ABS handle, etc.
Knife sharpener also has small and portable shape,it is made of diamond, tungsten steel, ceramics. Its hardness is high,with comfortable handle, easy to carry.It is not only suitable for kitchen use, and suitable for outdoor camping.According to the hardness of knife tools, so the harder the hardness of the knife tools to choose the higher hardness of knife sharpener.
