Do-it-yourself stainless steel thermos valve repair

In detail: do-it-yourself stainless steel thermos valve repair from a real master for the site my.housecope.com.

The principle of operation of the thermos lid is very simple. You press the button, the valve opens and the contents of the tilted thermos are poured through the hole into another container. The button is returned to its place using the internal spring of the valve.

Some manufacturers make it harder thermos button device, adding small details to the design that allow the button to work more smoothly, to ensure better tightness of the cover. But the more parts in the assembly, the higher the probability of failure of any little thing that will affect the operation of the valve as a whole.

The lid valve also has a number of disadvantages, which are due to possible clogging of the overflow, accumulation of deposits and, accordingly, the appearance of unpleasant odors.

Users of thermoses come out of the situation in different ways. Someone with a selected frequency cleans the lid of a thermos with a button, soaking the device in a solution of baking soda, others load the lid into the dishwasher, and still others perform a complete disassembly of the structure and mechanical cleaning of each component part.

All parts of the cover valve are made of food-grade plastic. On the one hand, you get a guarantee that harmful substances will not get into the liquid, but on the other hand, the strength of the plastic is low, and the valve mechanism and buttons wear out quickly.

In case of damage that is not associated with deformation of the valve and you only need to restore the connection of the structure or install the dropped part in place, you can do the repair yourself. Therefore, if Thermos button broken, do not rush to buy a new one, but try to disassemble the cover using our tips.

Video (click to play).

Let's consider three options for the device cover with a button. The first design is the simplest, with a minimum of details and everything is intuitive.

Here, the repair of the thermos button will consist in the usual disassembly and cleaning of the valve from deposits:

Unscrew the clamping ring counterclockwise. We apply sufficient force, but without the use of a metalwork tool. The ring is quite fragile and if there are signs of the part sticking, then soak the lid in hot water for a couple of minutes.
Take the valve out of the body.
We push the valve mechanism to do further disassembly.
We get three large fragments of the mechanism, it remains to get to the spring, button and other auxiliary parts.
We increase the set of parts with further disassembly of the button itself (usually it is fixed with fasteners).
Carefully push out the valve stem so as not to damage the retaining ring, we still need it for further assembly of the cover.

And here we have all the details that should be washed from deposits. As we can see, there is practically nothing to break here, only if the spring or retaining ring does not burst from wear. These spare parts can be picked up from other mechanisms or purchased at a hardware store.

VIDEO INSTRUCTION

The next version of the cover is complicated by the presence of a second button, but here, too, the manufacturers have provided for the possibility of disassembly. Rather, they did not begin to seal the mechanism, as happens when marketers of companies want to sell as many products as possible.

In this case, it is necessary to pry off the cover with a thin metal blade or other object.
The device has hidden latches that can be damaged if manipulated too harshly. Be careful.
As soon as you remove the cover, all the details will be freely available. To ensure that reassembly does not cause difficulties, we advise you to take a photo of the parts in the assembled state.

And that's why it was necessary to clean the valve. These are deposits that have accumulated over the year of operation of the thermos. Follow simple rules, and your health will be completely safe, and the thermos will last for many years.

Faced a similar problem.

I asked my wife to sew a cover.

The inside of the cover is made of flannel fabric.

Outside - from black leatherette.

Between these “shells” I placed a “insulation” made of cut-to-size parts of an old gymnastic rug.

The upper edging of the cover is made of denim, inside of which there is a cord for tightening the cover.

I have been ice fishing for over 10 years.

Perfectly keeps the temperature and does not rattle in the backpack.

Protects the body of the thermos from damage.

Drill at least two holes with a diameter of 3-5 mm in the outer part of the thermos body and blow mounting foam into them. The foam will fill in the voids and since it is a good heat insulator, it will retain heat well.

There are several options to repair an all-metal Chinese thermos:

First, opening the lower cover of the upper shell, get to the nipple and restore the vacuum by pumping out air with a powerful compressor. I will say right away that not every household compressor can do this, then it will be necessary to flatten and sunk the nipple in order to maintain a vacuum in the inner flask of the thermos. This is the most efficient way to repair.

The second way is to open the bottom cover of the case, cut out the bottom and pick up the required size of the thermos flask, just insert it inside the non-working one. Then fix it there with mounting foam and close the housing cover. This option is also quite effective and a thermos with a new flask will still serve.

The third and most ineffective way is to open the housing cover, remove the nipple and fill the entire space between the walls of the housing through the resulting hole with something insulating, for example, grated foam or cork. But after such a repair, it will be possible to keep only cool drinks or water in it, but hot tea will cool down very quickly, so that the thermos will lose its properties almost completely.

In general, there are several repair options - choose, in any case, you don’t need to throw away a stainless steel thermos, its parts can be used in everyday life, since food stainless steel is a high-quality and expensive material, it will be possible to make various kinds of almost eternal containers from them (cups, mortars, flasks , vases, ashtrays, etc.).

Sorry if it’s in the wrong section. I have a Biostal thermos. The valve button began to sink. It opens, but it’s problematic to close, it doesn’t snap back (the red one should have risen). Maybe someone dismantled this miracle device.

Try to hold it in warm water for a long time (it helped me, though I have a thermos from another office)

I’m afraid that when you do disassemble this valve, you will be shocked by the “virgin purity” of its insides

I didn’t deal with such a thermos, but I had to disassemble the Chinese valves - there are 15 parts there, although it looks simple

To begin with, hold the side edges of the cork with one hand, and with the palm of the other hand, resting on top, where the button is, try to unscrew the upper part of the valve in a counterclockwise direction. Further it will be easier to understand.

A side question, sorry. If there are different brands of thermoses with valves, then all of them (thermos) do not hold heat well? My 1.5 liter is enough for 2 hours, then the water is warm.

Most thermoses keep the temperature just fine. If the metal does not hold, then there can be two reasons: 1-violation of the vacuum between the walls of the flasks. Those. air got in. 2-inaccurate arrangement of the flasks among themselves, contact of the walls of the inner with the outer is possible. But this was a very long time ago, when the technology of metal flasks was just being worked out. This happened at the Ashinsky and Samara thermoses in the 90s.

Thank you. Thermos brand Vitesse. He didn’t keep warm from the very beginning, it turns out to be a marriage. Previously, there was a Tourist 1.5 l, they were very pleased with him. Unfortunately, by chance it was lost. A new one costs 800 rubles.

maybe someone will need it
ran into a similar problem, the red ring wouldn't snap back
the valve is disassembled like this - you need to pry (and not twist) the black ring on top with a sharp knife
the effort must be good, but the lid is strong - it will not break
minimum details inside, nothing complicated
I didn’t see any pornography inside, it’s just that all the details were in the raid
cleaned it all up and put it back together
worked like new

PS The thermos was bought back in 2007, but after 2010 it was not used much, the problem with the valve only got hotter now

Thanks, perovsky, I disassembled it, the mechanism, like in a fountain pen, there was a molding burr on the orange clutch, I cleaned it with the same knife I opened it, assembled it, everything works, nothing sticks, biostal thermos.

A short overview of a budget thermos in the price of up to $ 5 "A-Plus" 0.5 l stainless steel. Forgot to add to the review.

Which companies can be trusted so that as a result of use there is no question why the thermos does not keep warm?

Good afternoon, dear readers of my blog! I am glad to share interesting information again and today we will try to figure out together why the thermos does not keep heat and what to do about it.

Several of my friends complained that they were disappointed with the thermal dishes of well-known companies - they say that they have been using them for several months, and the heat almost does not hold on. Assuming that such a problem may await me in the future, I decided to take preventive measures. It turned out that the trouble can be corrected, but it is better not to let it happen. However, first things first.

There was little information on the Internet - only complaints and assumptions.But almost no suggestions to solve the problem. Then I began to interview friends who have such dishes. Everyone noted that at first the thermos did an excellent job with its direct duties and only after a while it stopped retaining heat. At first, I relied on my assumptions, which were partially justified.

In my opinion, the cause of poor thermal insulation can be:

From everything I saw, I concluded: a thermos, even a completely metal one, is a thing that requires delicate operation. Falls, bumps, shocks can lead not only to damage to the glass flask, but also to the disappearance of the vacuum and cracks in the valve plug.

Usually in such cases there is no question what to do - of course, buy a new thermos. That's what I thought until recently.

But some of my friends came up with creative solutions to the problem, and this is what they came up with.

A stubborn acquaintance of mine did a radical, permanent - as he suggests - solution to the problem with the vacuum. He simply filled the space between the walls of the inner and outer cylinders with mounting foam. How right he was about the durability of the thermos after such a repair - time will tell. But I found this way interesting. I'll have to try it on an inexpensive plate. In any case, now my friend's thermos is not so afraid of falling.

So far, I have not experimented, but tried to find out in advance which thermos keeps heat better - so as not to get into a mess, advising or buying such dishes as a gift.

To give a detailed answer to the question of how long food and drinks should remain hot in a thermal vessel, several nuances must be taken into account.

Flask material. Traditionally, it is considered that it is in thermal glass that heat is retained longer. This is 50% true, since glass has less heat transfer + silver coating plays a role.
The remaining 50% of thermos efficiency is based on vacuum. And if the model is made of stainless steel, then everything is 100%. So first of all, you need to make sure that the vessel is completely sealed and the vacuum is not broken.
The size of the vessel also plays an important role - the larger the volume, the slower the heat will leave it. But this item is relevant provided that the thermos is filled to the top.
Models in the form of a siphon - with a pump - keep drinks hot for no longer than 6 hours. This is obvious, because their cork is not 100% tight.

Summing up all the facts, I came to the conclusion that thermoses of well-known brands keep the temperature best of all, and it doesn’t matter if their glass or metal flasks. The main thing is high-quality vacuum. Firstly, a popular manufacturer will not risk its reputation and make a low-grade product. Secondly, when purchasing branded thermal cookware, you can always be sure that a defective model will be exchanged for you at any time, as some manufacturers give a guarantee for their products up to 100 years. For example, Stanley (USA). But this is only possible if you buy the product directly from official representatives of the company or the manufacturer itself.

I monitored the Russian market in search of the best brand and today it is:

"Amet" and "Biostal", production Russia. These firms have been familiar to the domestic manufacturer for more than a dozen years. We can say that this is an affordable quality that has stood the test of time. The advantage of Russian brands is that they are not counterfeited, and you can always find the full address of the company on the box.
Famous for 110 years brand Thermos. The brand concerns are located in England, Canada and the USA. But at the moment, the manufacturer has moved its factories to China. Do not be afraid of the inscription "Made in China", the main thing is that the coordinates of the manufacturer are indicated.
The German brand LaPLAYA is quite trustworthy - today in Russia they are produced by only one official company-distributor of Cold Technologies 2000.

It is difficult to say which of the listed companies keeps heat best, but customer reviews are only positive.

Never buy a thermos in the market, from your hands or in subway passages - no one is responsible for the quality of the goods in such places. Let's learn together, see you soon!

If you want to be in the know, I'm on instagram, where I post new articles that appear on the site.

Thank you for your attention! Sincerely, Rostislav Kuzmin.

Friend thank you very much. I spent an hour picking a thermos, I couldn’t figure out what was broken)

Krasava, the video is clear and necessary, not garbage on the Internet. Thank you for your help )

How long does your thermos keep warm? To keep boiling water for how long?

Thank you very much the video helped.

Many thanks. I didn’t believe that the quick-mount dowel head would fit on this cone, but it did.

Hammer . We will keep in mind. Come in handy.

Tell me how to fix a leak from a thermos. It leaks a little when I turn it over.

Well done! Thanks for the vid! I will also repair it myself, only the spring has gone somewhere (.

THX! My case turned out worse. When, when unloading from the car, the thermos fell out of the backpack and hit the lid almost vertically on the asphalt, then, as it turned out later, the aforementioned “cone” broke off. In its place, I screwed the screw of the required D (you can use a bolt) with a hemispherical head, since there was already a hole in the hollow valve stem, where the “cone” was made by the tide. (And if it wasn’t, then I would have drilled it.) You don’t need to cut the thread, the plastic is soft enough. Yes, the “native” retaining ring is fixed with the screw head even better than the “native cone”. And, of course, it is better to use a bronze or anodized screw or bolt; the shape of the head, so that the counterpart is centered, can be given by peeling.

Thank you, dear man 🙂 I learned how to disassemble the cover and finally, for the first time, in years. eleven cleaned the lid of tea leaves accumulated there over the years (or whatever it was). And then almost nothing flowed through the cork

Why didn’t I disassemble the button? Do I need it?

My puck is holding, but my spring has flown. I need to insert it back, but the puck can’t be removed. I don’t understand how to get it.

respect and respect to the author. thought kabzdets thermos, annet)))))

I have a slightly different build. the pin is not under the cone, but rectangular. I decided to put this docking on hot melt adhesive.

Huge thank you man.

well done, how much dowel?

What kind of deer do they put? I don't understand at all)

Hello. I have this thing that has fallen off, it has ceased to fit tightly and the thermos is now leaking. what to do with it?

Thank you fellow countryman helped, we have a Ramadan post, that’s exactly how I had an image, thanks,

He cursed, cursed, tried to do something, climbed into YouTube and, both of you! From the heart!)))

as an option, you can also find a retaining ring in size, you just need a stainless one. In general, brilliant, simple, reliable and fast.

I have another problem with the thermos please help

How do you make sure your thermos doesn't leak?

THANK YOU SO MUCH BROTH.

My brother gave me such a thermos, he says, they say, it flows. I watched this video and it turned out that the gum is on the contrary, turned it over and does not flow :)

Thanks, it's helpful! Checked how the sealing gum is holding up. (wife accidentally removed the thermos while rinsing).

super way! My thermos is also broken. I will repair. Thank you

and if the pressure valve broke off from the stem, how can it be repaired?

Why can't a person find the desired videos on Youtube? The thing is that a person cannot come up with something new and look for it. He ran out of fantasy. He has already reviewed many different channels, and he no longer wants to watch anything (from what he watched before), but what to do in this situation?
To find a Youtube video that suits your needs, be sure to keep looking. The harder the search is, the better your search result will be.
Remember that you only need to find a few channels (interesting ones), and you can watch them for a whole week or even a month.Therefore, in the absence of imagination and unwillingness to search, you can ask your friends and acquaintances what they are watching on Youtube. Maybe they will recommend original vloggers they like. You, too, may like them, and you will become their subscriber!

From an old thermal underwear I sewed a type of cover, I put a thermos into a cut-off sleeve from a “fur short coat”, then into this cover, boiling water on ice until the evening, a day later - normal tea, and then it becomes cold.

Perhaps a cover made from a tourist rug will be more effective (it can be made from neoprene if it is accidentally left lying around). It can be made from building insulation (porous, sold in rolls), but it is flimsy for wear.

And it is possible about the process of removing the plastic bottom in more detail?

here’s the finished device .. the bottom didn’t want to be removed, but it scrolled .. I cut it slightly with a knife with a psycho, took it off when I put it in place, glued the cut and tape around the perimeter .. although I think if I lowered the bottom into boiling water, I would take it off without a cut

Dima, I heard that you can’t pour boiling water over a thermos under a gum (cork). It can be inflated a little and micro cracks will appear.

So it was, just the person did not have time to instruct.

Not in the trash! I had such a case, and since the thermos was very expensive as a memory of a good person, I did the following:
Turn over and drill 4 holes at 90 degrees (large)
Between them are small 2-3 things
You drive foam sealant into the large ones so that it climbs out of the small ones
You put it upside down for a couple of days near the battery
Cut off what comes out
Keeps warm even better!

I tried to remove the bottom cover, but there is only access to the spout, and there is no space between the flask and the walls of the case, the edge is rolled on the machine. As I understand it, you need to drill the flask (first) ?.

I bought a second metal thermos in the Freken Bok store so as not to carry my fisherman back and forth when I was going fishing at the dacha. It costs 1000 rubles, yesterday I took it fishing, for testing - as a result, by the end of the day - the water is a little warm, the thermos is new, the lid fits snugly, so, drill and foam?

As for China, you are wrong, in 2003 I took a Chinese thermos, so it is still normal, boiling water all day, but the one I bought now does not hold. I’ll go with the old one, it’s just that the volume has ceased to suit, a liter is not enough for the whole day. Or maybe someone knows where there are not Chinese thermoses? In my opinion, everything is Chinese now. In the spring I bought a cool lamp in Amsterdam, and brought it home, began to consider it - made in PRC / True, it works and looks like normal

In Eldorado, I have a TERMOS thermos, I have a brown metallic, it keeps boiling water on ice for a day, the second is hot, I haven’t tried the third. The main thing is that the cork is not automatic, but twisted.

Made in China. The price is about 2000 rubles.
