The heating exhaust valve is rusty and can t be unscrewed, and the cast iron heating exhaust valve i

The heater needs to be deflated after a period of use, but if the deflation valve is corroded, it is extremely difficult to treat. Next, let's talk about what to do if the heating vent valve is rusty?

1. What should I do if the heating vent valve rusts to death?

1. After the rust dies, it can not be screwed strongly, it should be dripped or injected into the oil to wash and lubricate for a while, and then screw.

2. The brush can be dipped in diesel fuel to wash off rust.

3. Use a dense and hard wire brush to remove serious rust, grease, and plaster on the surface of the steel workpiece.

4. Wipe each part with non-woven fabric or precision filter paper dipped in pure alcohol until there is no dirty color.

5. First of all, drop a few drops of vinegar on the thread of the air release valve to let the vinegar soak into the air release valve; Cut a small piece of rag, soak it in vinegar and wrap it around the air vent valve; Use a convenient bag to cover the wet rag that wraps the air release valve, or you can wrap and tie it tightly, the purpose is to prevent the vinegar on the rag from volatilizing and dissipating or dripping; Leave it for 24 hours, then open the convenience bag, remove the rag, and you can easily unscrew the air valve.

What should I do if the heating bleed valve is leaking?

2. What should I do if the heating vent valve leaks?

1. There are many situations of exhaust valve leakage, which can be investigated from the outside to the inside, from simple to complex, to see if there is a problem. Generally speaking, the first thing to check is the exhaust valve, if the valve of the exhaust valve is not closed tightly enough, it may cause the exhaust valve to leak. Then turn it off again and tighten it with a tool.

2. Secondly, there is a possibility that the air in the exhaust pipe is not discharged, and there is a large amount of air in the floor heating pipe, which will also cause the exhaust valve to leak. At this time, you can exhaust in stages, unscrew the valve a little, do not open it all, drain the air and twist it, after a while, and drain it again until all the air in the pipe is discharged, and the water is discharged into the pipe, and it is discharged, so that the exhaust valve will not leak.

3. The heating season in winter has passed, and there is no need for heating in summer, and after a long time, there may be water rust in the exhaust valve, which rusts the exhaust valve, so that once the heating is sent, the pressure increases, and it will leak. You can loosen the exhaust valve and clean the exhaust valve port to solve this problem.

Heating. 4. If the valve plate in the exhaust valve is displaced, it may also cause water leakage. When the exhaust valve is deflated, the air pressure in the exhaust pipe is reduced, and the water leakage will be smaller.

5. If the exhaust valve is copper or alloy, because it has a screw mouth, it will be used for a long time, and the thread may seep out. You can unscrew the exhaust valve, wrap the thread with a sealed raw meal tape, increase the density, and then screw it on, and there will be no water leakage.

6. There is a rubber gasket at the internal connection of the exhaust valve, the rubber is easy to age, if the gasket is broken or aged, it will lose its toughness, and it may also cause water leakage. Replace it with a new one, and it won't leak. There are many ways to solve the problem, and it depends on the symptoms of the situation.

How to unscrew the cast iron heating exhaust valve after rusting:

1. First of all, confirm the material of the air release valve, and only then can there be a correct solution according to the material, which is a copper air release valve. The material used for the radiator a long time ago was brass, and the method used after the brass rusted was different from the method of other materials.

2. Second, confirm the degree of rust of the brass release valve, if it is a shallow layer of rust, it is very easy to deal with, if it is very rusty and is about to break, this time it can only be replaced, here is how to deal with a shallow layer of rust. <>

3. For shallow rust, you can remove the rust by using the method of thermal expansion and cold contraction, at this time you should prepare a candle, a lighter, a toothpick, and a wet rag.

4. Light the candle first, put it at the interface of the gas release valve, burn it with a flame for about 3-4 minutes, and then wipe it back and forth with a wet rag, connect it several times, this will hear the sound of the candle, pay attention to the outer flame of the fire when using the candle.

5. Use a wet towel to wipe back and forth a few times and then use a toothpick to remove the burned brass slag little by little, focusing on the rejection of back and forth in one position, at this time you can hear the sound of bubbling gas, and then gently twist the air release valve by hand, and the air release valve can be opened.

6. For brass rust, alcohol, vinegar, edible oil methods are not good, this is what I have tried, if it is other materials, then you have to find the corresponding method to solve it well.

After the rust dies, it can not be screwed strongly, it is necessary to drip or inject oil to wash and lubricate for a while, and then twist, or the brush can be dipped in diesel to wash off the rust and then drip into the oil for lubrication.

Gently tap the top of the handle with the smallest hammer, knock a few times, knock a few times, and twist until it is loose.

Is that the little copper exhaust valve?

Just spray it with a rust loosening agent.

Hello, kiss <>

Thank you very much for your patience <>

For you to inquire: the solution to the rust of the radiator release valve screw is as follows:1

After the rust dies, it can not be screwed strongly, it should be dripped or injected with oil to wash and lubricate for a while, and then screwed. 2.The brush can be dipped in diesel fuel to wash off rust.

First take a brush to dip the diesel fuel to remove the rust stains on the surface, and then add or inject oil substances such as rust loosening agent in the rusted place, wait for it to slide for a while, and then take a hard steel wire to remove the air release valve and the rough screw outer layer of the rough scratch carefully floating rust, grease, plaster, etc., and finally take a non-woven fabric or precision filter paper dipped in alcohol to wipe the parts one by one, to ensure that there are no stains, then use a wrench to unscrew it. I hope my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress. Finally, I wish you good health and a good mood!

The rust of the heating exhaust valve can be opened by using the principle of thermal expansion and cold contraction, which is introduced as follows:

For shallow rust, the rust can be removed by the method of thermal expansion and cold contraction, at this time a candle, a lighter, a toothpick, and a wet rag can be prepared.

Light the candle, put it at the interface of the air release valve, burn it with a flame for about 3-4 minutes, and then wipe it back and forth with a damp rag, connect it several times, this will hear the sound of the candle, pay attention to the outer flame of the fire when using the candle.

Wipe back and forth with a wet towel a few times and then use a toothpick to remove the burned brass slag little by little, focusing on the rejection of back and forth in a position, at this time you can hear the sound of bubbling gas, at this time gently twist the air release valve with your hand, and the air release valve can be opened.

Notes:

1. After the heating is over, the heating user should not discharge the water in the system, and need to carry out "full water maintenance" on the radiator and pipes, especially for steel radiators. Full water maintenance is to use the water in the radiators and pipes to effectively isolate the air, reduce the risk of erosion of the radiators and heating pipes, and can prolong the service life of the heating system.

2. During the heating period, in order to prevent the inner wall of the radiator and pipe from being oxidized and corroded, the heating company will add chemicals to the heating water to neutralize the ions in the water and adjust the pH.

1. After the rust dies, it can not be screwed strongly, it should be dripped or injected into the oil to wash and lubricate for a while, and then screw.

2. The brush can be dipped in diesel fuel to wash off rust.

3. A dense and hard wire brush can be used to remove serious rust, grease, and plaster on the surface of the steel workpiece.

4. Non-woven fabric or precision filter paper can be wiped with pure alcohol until there is no dirty color.

Note: Apply paint to the heating valve. This prevents the valve from being directly connected to the air and prevents the valve from rusting.

And do not leave the heating valve in a humid air environment, which is prone to rust. The valve should also be cleaned regularly. If you see dirt such as foreign objects, oil stains, water droplets, dust, etc., you can wipe it with a cloth to keep the heating valve clean.

Add a few drops of carbonated drink or vinegar and try it in a few minutes.

Add a few drops of lube, moisten for a few hours, and try again.

It really doesn't work, go buy some oxalic acid, put a few drops on it, and try it after a while.

Pour some oil on the top, you can tighten it in the direction of tightening and then loosen it, several more times.

The safest thing to do is to change the exhaust valve or buy a rust remover.

The valve and the release valve are rusty and cannot be screwed, do not force it, otherwise it will damage the valve and the release valve, and the consequences will be very serious. Jin Flagship suggested that the main valve should be turned off and a professional master should be found to replace the valve and air release valve.

Rust removal with rust loosening agent can also be used to soak in hydrochloric acid or sulfuric acid to remove rust, but the two have strong corrosiveness, pay attention to safety in the treatment process, and do anti-corrosion measures after cleaning, it is not as convenient as using rust loosening agent.

The heating exhaust valve is rusty and can't be broken, and the following methods can be solved:

1. If the heating valve is rusted to death, we can drip some oil, whether it is engine oil or edible oil, or some other lubricating oil, in short, after dripping into it, we can screw its valve.

2. If you really can't screw it, we can use a brush to gently brush out some rust on the outside or directly use a steel wool ball to rub off all the rust on the outside, and then add some lubricating oil to try to unscrew the valve again.

3. If the above two methods are still inseparable from the valve, then we can drop a few drops of vinegar in a plastic bag, and then soak the plastic bag in a wet bag, cover the valve, and then wrap it with a damp cloth.

Precautions for the use of heating

1. In the process of using heating, we must do a good job of indoor heat dissipation, if the indoor heat dissipation can not be successful, it is likely to cause certain harm to the heating and reduce its use of organisms.

2. In the process of using the heating, the heating must be exhausted regularly, if there is air in it, it is likely that the heating will not be able to supply heat if it is not discharged in time.

3. If you want to change one direction of the radiator, you should also ask professional personnel to help us operate it to prevent yourself from transforming it and bringing unnecessary losses to your home.
