Smell of gas during or after operation of the gas cooker. How to fix a gas leak from a gas cylinder with your own hands Gas burner leaks gas
If one day, while driving, in your car equipped with gas equipment, you heard smell of gas, which is clearly felt, you should immediately take measures to eliminate this malfunction, as well as to establish the cause of its occurrence. How to do this, we will tell in this article.
If the HBO is functioning correctly, there should not be any extraneous odors associated with gas in the cabin and you must understand this, no excuses like: "The car is on gas, it stinks ..." - be shouldn't! Compared to the smell of gasoline gas smell in the cabin can cause a lot of trouble...
If the smell of gas in the cabin appeared shortly after the installation of HBO, this can only indicate one thing - the gas equipment was installed with violations, most likely there is a leak in the connections or in the HBO itself, or components of very poor quality. For example, fuel hoses, reducer, gas cylinder etc. As a rule, installation problems arise in the case of installation gas system"with your own hands" or in some "unfortunate workshop". Such service stations, in pursuit of a client, try to lure those who want install hbo on car at any cost, and in order to reduce the cost of the gas kit, they use low-quality materials, or a fake, which later can cause gas in the cabin and even a great tragedy.
In order for HBO to serve for a long time, and you do not worry about your safety, you should buy only branded components, even if their significance in the system, in your opinion, is very insignificant. In addition, it must be carried out only by qualified specialists at a service station that has all the necessary permits to perform this type of work. Gas supply hoses must have high strength, hoses found somewhere from something to use IT IS FORBIDDEN! Only strong gas hoses and clamps can ensure tightness and save you from gas leaks.
If the smell of gas is heard in the exhaust, this may indicate an incorrectly adjusted gas installation. Each has its own differences, some of them require calibration during operation after a certain time. Go through those regularly. installed on your car, after a period of time set by the manufacturer. Change the gas filter every 10-5 thousand kilometers.
And the last. If you found gas smell in the cabin, that is, a leak while the car is moving - IMMEDIATELY stop, close the valves on the gas cylinder, ventilate the passenger compartment, and continue further movement on gasoline. Moreover, it should be understood that you do not need to go home, not on business, but to a service station that can check, find the source of the gas leak and eliminate it quickly and safely. Take care of yourself and be vigilant!
It doesn't matter where you smelled household gas, in your country house, in an apartment or an entrance on a landing - a gas leak is a serious danger to the property and health of people around you. Gas with prolonged leakage accumulates in a confined space, turning into an explosive mixture that can detonate at any time. That is why we recommend calling the gas service at the slightest smell of gas. But if you live in a country house remotely from gas facilities and calling a gasman to your house is impossible for some reason, then read our article to the end and you will learn how to find a gas leak in the stove and quickly eliminate it.
Gas leakage in the stove occurs for several reasons:
. Hose gasket burst or pressed through;. Hose connection nut loose;
. A hole has formed in the hose;
. The sealing gum of the crane has weakened;
. The gas cock was loose;
. Lack of lubrication of the tap plug;
. The installation of the plate was carried out by an incompetent person.
Household gas has no smell. In order to give it a sharp bad smell: the chemical odorant ethyl mercaptan is added to it. This is done on purpose so that a person can feel an unpleasant smell and respond to its presence, so the first sign of a gas leak in the stove is an unpleasant smell, reminiscent of the smell of rotten eggs.
When you light a gas stove oven or hob burner, a small amount of gas may enter the kitchen area and give the illusion of a leak - this is normal. But if, after turning on the stove and during long cooking, you constantly feel the presence of gas, most likely the tightness has broken somewhere, which requires attention on your part, namely search and elimination.
How to find a gas leak in a stove
ABOUT open the oven door. If the smell of gas has become stronger, a thorough inspection of the gas stove faucet will most likely be required, as from prolonged use, the faucet mechanisms can dry out and leak a little. Read more in this article: Repair and adjustment of gas valves.
IN slide the plate away from the wall. If you smell a strong smell, most likely there is a gas leak in the stove connection. You should purchase a new hose with paronite gaskets and install in place of the old one. If there are no visible defects on the old hose, you can get by with replacing the gaskets alone.
IN the stove is off, the smell of gas from the burners. At the moment, such a malfunction is irrelevant, since gas control is installed on modern stoves. When the tap is turned off, the solenoid valve shuts off the gas supply to the burner and eliminates leakage. In hobs, a leak at this point indicates a poor connection between the gas hose and hob. The gas is lighter than air, it rises and accumulates under the panel. In this case, you can feel a distinct smell around the switch handles. You can always use our services and call our master for diagnostics and subsequent repair of built-in panels.
P search with soapy water. From the dishwashing detergent, prepare a soapy solution with a small foam. Apply the solution to everything threaded connections pipes, hoses. Any bubbles you see indicate a gas leak.
Use the services of professionals. All repair services have gas leak detectors. You can always invite a specialist to your home for diagnostics. If you live in a country house, you can buy such a device for personal use. The leak detector does not take up much space - it is a small portable device that runs on batteries. All you need is the correct setting.
Advice: With be quiet and listen. Gas leakage occurs due to the pressure in the system, which is trying to be released to the outside. If you're lucky, you might be able to hear and locate the leak.
If you feel it is real danger for life and health. When the stove leaks for a long time, blue fuel tends to accumulate in a confined space. This forms an explosive mixture. It can detonate at any favorable occasion. Therefore, any such symptoms are a reason to immediately contact the gas service. And I will tell you what the cause of the breakdown may be so that you do not hang noodles on your ears and teach you how to identify a leak.
Doesn't even give 100% leak protection, however, high quality assembly and components can push this moment indefinitely. That's why I advise you to initially choose good plates.
By the way, I met quite decent options even in budget lines from domestic manufacturers. What do they cost - not without problems, of course, but in terms of reliability, it’s quite a good option. Gorenje equipment demonstrates excellent performance in terms of operation. But, it all works with proper connection.
So let's get back to our sheep. Leaks occur due to the following causal factors:
- hose problems: the hose gasket was squeezed, damaged, the hose gasket burst, the hose connection nut was loosened, the hose itself is full of holes;
- faucet problems: the sealing gum of the tap is worn out, there is no lubrication on the tap plug, it is loose;
- the tightness is broken in the plate due to weakly twisted internal connections. By the way, a seal failure could also occur during transportation;
- incorrect installation, wrong settings . On the one hand, safety and household gas appliances are not allowed to independent work by connection. On the other hand, the expanses of our homeland are full of bearish corners, where handicraft installers openly hack and commit gross violations of safety regulations. In addition, they often miss such a moment that the stove always comes with factory settings - for a gas network or liquefied gas. Perhaps this is the cause of the problem. Gas can pass a cylinder, as a rule, the connection with a flexible hose is vulnerable here, as I mentioned above;
- exploitation violations: milk has escaped in the stove without gas control, you are not around, the flame has gone out, and the gas is coming;
- hotplate defective- there may be a factory marriage, or natural wear and tear. In most cases, it is jammed or replaced with a new one.
How to locate a leak
Actually, the smell of gas may not be felt immediately, especially if a window is open in the room. But, during cooking - quite. In order not to miss this moment, household gas add an additional component - mercaptan. This fragrance is an extremely smelly compound. In theory, it should warn of a leak long before the concentration of blue fuel reaches an extremely dangerous level. But, in practice, anything is possible.
The fact is that natural gas in the bulk is butane, propane, in some quantities there is propylene, ethylene. All this explosive mixture has a psychotropic effect. The person loses sensitivity and does not hear the smell of the perfume.
I'll tell you straight away If you smell gas, turn off the gas supply immediately.. You should not turn on the light, smoke and do anything that can cause a spark. It is better to de-energize the entire apartment altogether and ventilate it well. So at least nothing will blow up. It would be nice to take everything mobile devices, turn off the landline phone.
So, the main methods for detecting a leak are as follows:
- believe your eyes. This is the first and completely official method problem detection. The gas pipes leading to the burners are wetted with soapy water, including the places where the hose is connected to the stove, connections above and below the gas meter. The places where bubbles form are determined by eye. Most often, this is where there is a leak, which is caused by loss of tightness. If you see any small bubble, stop immediately shut-off valve and call the gas workers;
- trust your own ears. If the leak is severe, the blue fuel will whistle distinctly;
- by smell. Actually, this is where we started.
What to do
To begin with, I want to say a few words about the tools and. All gas fittings are made on the basis of alloys (usually bronze) that do not give sparks. This is what should be used for repairs. Of the repair tools, you will need pliers, an adjustable wrench, gas key for stove No. 1, gas key for valve No. 2. Plus, a special paste for insulation.
If the problem is in the burners
If the smell of gas is due to an extinguished flame, and you discovered such a burner too late, turn off the supply and ventilate the kitchen. Feel free to open doors and windows. Then you have to wait until the burner cools down. Here you can blow out the holes, clean them of fat, food debris.
This cleansing is a must. The point is the remnants of salt, or rather sodium, which is contained there. When it heats up gives an intense color in the yellow part of the spectrum. This can be confusing, giving the appearance where it doesn't exist. When everything is ventilated, cleaned and set in place, you can light it again. In case of malfunction, a replacement is carried out with a new one.
If the stove is powered by a cylinder
If the check showed that the leak is coming from the cylinder, call the gas workers and, if there is a balcony, carefully relocate it there, covering it with dense wet sackcloth for greater safety. If the leak is at the connection and there is nowhere to pull the cylinder, you can also cover the hose with a wet rag while waiting for service 104 . By the way, if this thing is hot, it is better not to touch it at all.
Under the supply pipe ½ '', you can build a plug from the old wine cork. Cut her like a cone sharp knife and insert firmly. By the way, you can later extract it with a corkscrew. Any open pipe should be plugged. Additionally, I note that the rag should be just wet, not damp. The fuel is supplied at low pressure and is not able to squeeze moisture out of the fabric. This works for almost any leak.
If the problem is in the hoses
I note right away that the purchase of hoses should be carried out only in specialized certified stores. Visually, they are distinguished by a bright yellow braid. Don't forget that the savings this case- the price of life.
The hoses themselves can be metal corrugated in a yellow plastic sheath or rubber in a metal sheath. The first option is twice as expensive, but it will also last an order of magnitude longer. However, rubber is difficult to damage, it does not crack if accidentally bent. A good rubber hose will also last a couple of decades.
So, if the hose itself is damaged, it should be replaced with a new one. If isolation is the problem, it is restored. Thread isolate linen tow, which is impregnated with a special paste for gas equipment(type "Unipack"). Some craftsmen put Teflon or fum tapes, but over time they will give an insignificant, but still dangerous leak. Leave this option for water pipes.
I note that the new hose cannot be sheathed, no matter how much you want - it must remain available for inspection. The allowable length is up to 4 m. As a rule, this is enough for any kitchen and there should be no problems.
If the shut-off valve is leaking
This is also one of the most common problems that can affect any stove over time.
The valve can be checked like this:
- take key number 2, grab the valve. Using key No. 1, we clamp the nut of the outlet to the plate, carefully unscrewing it;
- apply a soapy solution to the valve nozzle;
- if it pulls, we call the gas workers, shut off the gas supply. Well, if there is a new valve, impregnated linen;
- the master will unscrew the old valve with two keys, quickly plug the pipe, wind the insulation;
- then the installation of a new valve will follow - this is done quickly, in almost seconds;
- the connection is tightened with a key until it is in the correct position;
- correct installation is checked soapy water. Additionally, it is better to paint over the threaded joint with oil and only oil paint.
If you smell gas from under the handle
Here you can do something yourself. But first you need to make sure that the leak comes from the adjusting knobs, using a soapy solution. An indirect sign of this malfunction is the tight travel of the regulators.
If the diagnosis is confirmed, check and lubricate the adjustment mechanism located under the handles:
- having previously cut off the gas supply, the handles are removed, as is the front panel. To do this, just remove the screws and latches;
- then the valves themselves are removed. At this stage, the studs holding the stem are unscrewed;
- take out the plug and spring (I advise you to remember their original position);
- the plug is cleaned of dirt, residues of old grease. Do not take metal needles, knitting needles, this will cause scratches, which will cause even more leakage;
- we process a clean cork with a special graphite lubricant, carefully, so as not to close the holes;
- the stem is also cleaned of dirt, grease, wiped with a dry cloth;
- the plug is inserted into place in its original position, then the spring, the stem is fixed;
- as a result, the functionality of the control valve should be restored, which can be immediately checked. Next, handles and are installed in place.
In addition, I note that during operation, the handle with the stem can pop out of the cork. Here the reason may be the loosening of the connection of the stud, which is fixed with a thread. If a pin is lost, it can be replaced.
If gas poisons from under the nut at the burner
This problem is often found in old gas stoves, in two-burner, Delta, Aksinya. Here you just need to tighten the nut until it stops. Act, as with, should be careful. Otherwise, you can break the thread and the problem will not be fixed. I can say that getting to this node is not so problematic, you can handle it yourself.
conclusions
If you have at least 101 gas stoves, always read the operating instructions. You never know what the manufacturer came up with this time. One more piece of advice: do not be too lazy to study SNiP 2.04.08087 “Gas supply” - here you can also scoop up a bunch of information for your own safety.
I will not tire of repeating that The best way repair is the challenge of a professional gasman. With blue fuel jokes are bad. Don't skimp on qualified help. Such thrift always turns sideways.
Gas - chief assistant cook and stoker, it will not be cold and hungry with him. Knowing the safety rules and behavior patterns during emergencies will save you from troubles and help strengthen your "friendship" with the gift sent to us by Mother Nature. Still don't know what to do when you miss gas cock in the kitchen and how to check if there is a leak? Well then, let's get down to business.
You probably know that natural gas comes to our kitchen directly from the bowels of the earth, naturally, bypassing kilometers of pipes. The main combustible component of the gas is methane. It is he who is a threat to human life if he leaves the pipeline. A 5% concentration of this substance in the air is enough, and if you do nothing, ignition or explosion is inevitable. “Why does everything have to end in fire?” - you ask. As a rule, due to ignorance of the rules of behavior in such situations, people do not stop using electrical devices (sometimes they even turn on the light to understand what kind of unpleasant smell goes from the kitchen), or even at all, when sometimes the gas tap in the kitchen poisons, they bring a lit match to the stove in order to understand which burner is broken.
Worth paying attention! Natural gas, you may be surprised, has no smell, as well as taste or color. Therefore, it is odorized before being pumped into the pipes leading to consumers - it is saturated with a substance with a specific, unpleasant odor, which is harmless to humans and helps us to know about a gas leak from the system.
According to the rules for handling gas, the population is prohibited from dismantling or repairing pipes on their own. But what if the gas faucet in the kitchen skips? First, open the doors, windows. Secondly, stop using electrical appliances. Third, call the appropriate service.
What to do if you suspect a gas leak, but you are not sure about it, do you exclude that everything seemed to you? There is a way to check the correctness of such an assumption. Make a soapy solution and apply it to the faucet or areas where you think gas might be leaking. If, however, there is a breakdown, then bubbles should appear, moreover, of a solid size. Doubt? Do the operation again, because calling the emergency service because of baseless suspicions is also bad, isn't it?
It looks like one of the models of the gas valve
Crane repair and lubrication
Naturally, according to the rules, it is better to invite a master, but many men consider themselves sufficiently "savvy" in order to produce repair work on one's own. Well, this can be, especially if the owner of the house has already dealt with the repair of gas pipelines and specialized equipment.
Consider a version of a mini-repair - lubricating a gas valve.
What will be needed to carry out the work?
- screwdriver;
- gag (made of wood or in the form of a wet cloth in plastic bag);
- lubricant (from graphite or grease);
- textile.
Make sure that nothing interferes with you, you should approach the pipe tightly, if necessary, move the stove away
Of course, it is better to shut off the gas supply for the duration of lubrication. But it happens that this is not possible, then try to lubricate the tap without overlapping. Disable Appliances, open the window, put out the fire (candles should not be used either).
Using a screwdriver, unscrew the plug on the tap, remove the spring, and then the cone. Close the hole with a gag. Remove dirt and old grease from the valve, apply a new mixture. Remove the gag (you need to do this very quickly), replace the shutter, spring and plug. Check the tightness in the way you already know with a soapy solution. No bubbles? It means that you have successfully completed the job, the crane is lubricated and will work properly. If the leak does not stop, call the gas service immediately.
It's important to know! Allow specialists with supporting documents to carry out such work, including a license, to the process of connecting any gas appliances. During the work, be nearby to come to the master to help if necessary. "Armed" with soap, do not forget to check the quality of work.
The faucet has been replaced, it remains only to paint the pipe
Now you know what to do and how to behave, if the gas valve in the kitchen skips, then your house will always be safe.
