What is the section of the screw under the water gas linkage valve of the gas water heater for what

Function: This is used to adjust the minimum water pressure of the starting water heater.

A screw connects the plastic tympanic membrane inside.

The left side of the eardrum is connected to the right side, which controls the left and right water pressure of the tympanic membrane, and further controls and adjusts the push rod strength connecting the tympanic membrane.

Note: If you want to ensure the constant flow rate, it is recommended not to use a bypass valve, but to use a bypass pipe and add an orifice plate for flow limiting, which is better. The main consideration was that the valve does not need to be opened and closed frequently, and there is no need for flow regulation, so it is easy to leak.

Like the gas stove, the gas water heater is the first to ignite, and then release the gas, the water-gas linkage valve can touch the ignition switch, but the reason why it can't be turned on is that the water-gas linkage valve has been unable to further release the gas. Supplements).

Causes of abnormal operation of water-gas linkage valves:

The fouling of the inside of the water heater and the hot water pipeline causes the blockage of the hot water pipeline, resulting in a large flow back pressure of the water channel and insufficient pressure difference in the linkage device.

Treatment: It is recommended to clean and descale immediately, and you can buy a set online.

For gas water heaters, do not remove the scaler, use it to inject descaling agent into the water heater to clean the inside of the water heater and the inside of the hot water pipeline.

This is used to adjust the minimum water pressure of the starting water heater; One screw connects to the left side of the plastic tympanic membrane, and the other connects to the right side, controls the left and right water pressure of the tympanic membrane, and further controls and adjusts the push rod strength connecting the tympanic membrane.

This is above the water inlet of the water-gas linkage valve, right?

My family's is the same as yours. Pick the whole screw in the lower position of the micro switch and move it. That's it.

Has it been like this ever or has it been a recent occurrence? Because the minimum starting water pressure of the machine is adjusted when it leaves the factory.

There should be two places where this can be corrected.

The micro switch part, this part is generally fixed, you can see if there is a margin for adjustment. There is also the possibility of adjusting the gap with the lever that pushes the micro switch.

Water tray, I don't know how to adjust it.

In addition, note: the starting water volume is adjusted too small, because this water heater cannot automatically adjust the temperature, and the water temperature may be too low and cause scalding. If this is the case all the time, it is recommended that it is best not to make adjustments, and the manufacturer must have a reason to adjust to this value.

Is it that the water-gas linkage valve has to be changed to a keen one after a long time?

Since your kitchen can be lit and the water output is larger, it proves that there is a problem with the water output of the shower in the bathroom, which is generally too small, you remove the shower and use the pipe switch directly to see if it can ignite, if it can be ignited, it is the problem of the water from the shower. It is estimated that if you are not good at handwork, don't dismantle the water-gas linkage assembly, as long as the micro switch is not rusted and deformed, don't fix it at will, it's not the problem, it's just that the ignition time is sooner or later. And you can't pinch it too much, you have to have enough room to be safe!

Water-gas linkage is both dynamic temperature control and safety control.

This kind of problem is the most common problem with water heaters, and it is necessary to check the water flow control part to ensure that you have no problem getting out of the water without ignition!

So first the periphery and then the water heater, first simple and then complex! This avoids unnecessary tossing or even man-made damage without solving the problem!
