Gas is the main assistant of the cook and fireman, it will not be cold and hungry with him. Knowledge of 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 do not know what to do when the gas valve in the kitchen is leaking 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 bad smell comes 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, no taste or color. Therefore, before pumping it into the pipes leading to consumers, it is odorized - saturated with a substance with a specific, bad smell, which is harmless to humans and helps us to know about gas leakage 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?

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. Turn off household appliances, open the window, put out the fire (you can’t use candles 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 a way already known to you with soapy water. 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.
What should I do if I smell gas in the kitchen? It is highly likely that this is leaking the gas valve, which is located directly in front of the device.
As soon as you smell it, you should call the emergency service, because the gas is very explosive.
But it is also worth knowing how to deal with such situations yourself. If the faucet is to blame for the leak, then it is better to replace it, for polypropylene pipes fitfrialen 63 ball valve. But it may be enough just to lubricate the faucet.To do this, we will study in detail the instructions on how to scrupulously lubricate the tap.
Tools and materials that we need in the work:
Flat slot screwdriver
Rag
Gag
Graphite, grease or technical vaseline
Soap
We act in order:
1. Examine the gas faucet, paying attention to how the main body of the faucet is made. It can be made in the form of a conical shape with a hole through, or pressed by a twisting spring using a special plug.
2. Turn off the gas supply to the house or apartment about the possibilities, this minimizes the possibility of an accident. If the gas could not be shut off, then you can work like that. Just need to take into account important rules:
Unplug all electrical appliances from the socket;
Ask all people not involved to leave the room, if possible, from the premises.
Make sure there are no open flames in the room and never smoke while you work.
3. Next, unscrew and remove the valve from the tap and plug it with a gag to reduce the gas flow. Carefully remove all old grease with a dry cloth and apply new grease without sealing the holes.
4. After everything is done, you need to very quickly replace the gag in the gas valve with the shutter. Carefully twist the spring and clamp it with a stopper. We resume the gas supply if you blocked it earlier.
5. Ventilate the room well. Then prepare a soap solution and apply to the faucet. If there are no bubbles, then you have done the job. But still, when there are bubbles, try to reassemble the faucet again and check the leak in the same way. If the problem persists in this case, call the gas service immediately. Since even the smallest leak can lead to a destructive explosion.
A positive feature of Soviet gas valves is their long term operation and maintainability. However, such a faucet requires regular maintenance, since the tightness of such a device is ensured by grinding the faucet plug to the body, read more about this in our article.
The appearance of a smell of gas in the area of \u200b\u200bthe plug valve is by no means a reason to replace it, however, you still have to call a representative of the gas service to eliminate the cause of the leak.
This article describes step by step the revision process of the two most popular gas plug cone valves: coupling and tension. Note that this article is not a call to action, but is offered for informational purposes only, since gas hazardous work must be carried out by specialized organizations that have the necessary permits. It will be useful to those who wish to see for themselves the quality of the valve revision carried out by the gas service.
Preparatory work
Before proceeding with the revision of the gas valve, it is necessary to find out whether the valve is really the source of the leak. To do this, it is necessary to soap the tap by applying foam to the joints. We find gas passages to make sure that the faucet is really the cause of the leak.
Note. Hose leading to gas equipment, was specially removed to show that a gas leak from the outside very often means a leak in the faucet itself. Because the options to lubricate the body with grease for outer surface, glue with plasticine and others folk methods do not completely solve the problem, but only create the illusion of security.
To carry out an audit, there is no need to remove the gas valve from the gas pipeline. In this article, this is done solely for the sake of clarity of the process. However, it is necessary to shut off the gas supply to the gas pipeline and relieve pressure, as well as warn the neighbors to turn off all gas-consuming devices!
Required Tool
To perform an audit, you will need the following tool:
- wide flat screwdriver
- open end wrench No. 17
- grease for gas taps
- rag
Note. In the absence of a special gas lubricant, it is quite possible to replace it with graphite lubricant. It is undesirable to use grease, because its properties are highly dependent on temperature.
The process of revision of the tap cork cone coupling
Loosen the screw plug with a flat screwdriver.
We take out the spring.
With a flat screwdriver, turn the tap plug a little, pressing on it. Hold the cork with the finger of the second hand. When it is jammed, you can tap the screwdriver a little with a hammer.
Note. Do not damage with a screwdriver inner surface faucet and do not drop the cork, to avoid scratches and nicks!
We take out the cork.
Wipe the faucet body and plug with a rag. Dried grease can be removed with gasoline or alcohol.
Use a screwdriver to remove the remnants of the old grease from the cork.
Apply a thin layer of lubricant to the cork.
We place the lubricated cork in the body.
We fill the grease into the cavity where the spring is located.
We place the spring in the groove of the cork.
Lubricate the threaded plug and screw it into the housing for several turns with a screwdriver. The spring should fit into the groove on the plug.
Tightening the screw plug with a screwdriver, we adjust the smoothness of the tap. We check by turning the plug with a screwdriver. The crane should not turn with effort, but it should not go too easily.
The process of revision of the cork tap
Holding the faucet plug with a handle, unscrew the locknut and nut in turn with the 17th key.
Remove the restrictor.
We press a finger on the cork pin, turning the cork with a handle. When the plug is jammed, you can tap the stud a little with a hammer, after screwing the nut onto it, so as not to damage the thread. You need to hit the nut!
We take out the cork.
Cleaning of the plug and body, followed by lubrication and assembly, is carried out in the same way. sleeve valve. We clean the restrictive washer from the old grease.
Apply grease to the valve body at the contact point of the limiting washer.
We put the limiting washer on the groove of the stud. To do this, put the tap plug in the half-open position.
We screw the nut with a slot to the tap plug.
Clamping the nut, we adjust the degree of tension of the valve. We check by turning the faucet handle. The crane should not turn with effort, but it should not go too easily. We tighten the locknut.
Once again, we check the smoothness of the move.
Results of the work done
After gas supply and control soaping, no gas leaks were found! The tap is airtight and began to work much more pleasantly, without jamming!

If it’s fast and homely, then it’s possible with a CV joint, and lithol, but if it’s good, then ...
Grease LZ-GAZ-41 (TU 0254-322-00148820-98) is intended for lubrication of plug valves of household gas equipment. Has the ability lap the rubbing surfaces, improving the tightness of the taps as they work.
Lubricant LZ-GAZ-41 has high temperature and chemical resistance, is insoluble in water, non-aggressive to valve materials household gas stoves.
Lubricant LZ-GAZ-41 is made on the basis of mineral oil thickened with lithium-calcium soap with the addition of anti-corrosion and antioxidant additives and solid fillers - molybdenum disulfide and acetylene black.
When such a thing was needed, I went to Gorgaz (on Krasnoznamennaya St.), thinking of catching some uncle-repairman there and asking him for a bit of this bullshit ... Having walked a little along the fence (they had lunch or something) suddenly discovered his brother as such an uncle (IMG:style_emoticons/default/blink.gif) (I didn't even know that he already works there)... but another one could turn up. (IMG:style_emoticons/default/smile.gif)
Now there seems to be a shop there, in the same building, but are there any lubricants there ...?
By the way, there is no need for special heat resistance, the main thing good seal and long-term reliability.
In principle, you can take a small needle file and cut a soft lead from a simple pencil.
Knead it with the same lithol or cyatim and it will be a type of heat-resistant lubricant.
Graphite does not add heat resistance at all.
Valves are lubricated with grease operating temperature up to 150 degrees, this is not a heat-resistant grease at all.
Lubricant resistance is determined by the soap agent, not the graphite.
Theorists? Graphite grease is better. Even with many years of use, if it dries up, it is removed more easily than a sticky ordinary one.
When operating with the oven door ajar (when drying mushrooms, for example), more heat is supplied to the faucets than usual. So it’s better not to engage in perversion, but to buy a normal lubricant, since the thing is quite inexpensive.

More, how much?
Mobilgriz is much better than the one that the gas workers have.
And what about graphite? Drying depends on the base and soap.
More, how much?
Not higher than 150 degrees in any case, otherwise the handles will burn out and melt.
Mobilgriz is much better than the one that the gas workers have.
I don't understand, are you a gas or air conditioner?
Can you help me install a simple split system if I buy it? How much do your services cost? Look outside and indoor unit I'll set it up where it suits me. All electrics by myself. There are either four or five wires. I only need to connect the tubes, pump out the air, and so that everything floats correctly. I don't have such a tool.
