How to tell if there is an air leak in the cylinder?

Hello, mainly from the following aspects.

First, it is necessary to grasp which places are prone to air leakage, and check the connection parts. In general, cylinder angle valves.

There is a fault, the pressure reducing valve.

Air leakage can be caused by the handwheel not being tightened, the sealing rubber ring falling off or being damaged, the hose aging, burning, cracking or the connection being too loose, and the sealing of the cooker rotor door is not tight.

2. When you walk into the kitchen and smell the strong LPG.

When you smell it, you will immediately think that it is an air leak. At this point, you don't have to panic, first of all, open the doors and windows to reduce the concentration of LPG in the room. Then, use a soft brush and brush dipped in soapy water to apply the parts that are prone to air leakage one by one, and find that the continuous foaming is the air leakage point.

If there is no abnormality in the area prone to air leakage, it is necessary to check the cylinder body again.

3. If it is found that the connection parts are not tight and the air is leaking, adjust them to no air leakage. If the seal diagram of the pressure reducing valve is deformed or the hose is cracked, replace it with a new one. If the rotor door of the cooktop is not tightly sealed, butter can be applied.

If it is a failure of the angle valve, pressure reducing valve or crack in the cylinder body, it cannot be dealt with by itself, and it must be sent to the ** station for repair and replacement.

Fourth, in the process of checking and dealing with air leaks. There must be no open flame indoors, no electrical appliances, no convenience? It is not possible to directly detect leaks with open flames.

1. Quickly close the valve of the gas stove switch and gas pipeline. If it is indeed a liquefied gas cylinder, move it to an open space outside for ventilation;

Indoors.

2. Extinguish all fires, it is strictly forbidden to open or close (especially when it is closed, let him open and close, there will be sparks) any household appliances, and do not use indoor fixing**and moving**;

3. Open doors and windows immediately for ventilation;

4. Call the gas company in a safe place to report for repair** and wait for the arrival of rescue personnel, if the leakage is serious, you should evacuate quickly and call "119" to the fire department at the same time;

When it comes to safety, I don't dare to answer casually, and it won't be wrong to open the window for ventilation.

What type of gas cylinder, close the main valve.

The most straightforward way:

The first step is to smell with your nose, if there is a leak, it must be very smelly.

Step 2: Find out where you think it will leak and apply soapy water, if it bubbles, it will leak.

The most likely place for air leaks:

1. Cylinder angle valve (the inner sealing ring is damaged or aging);

2. The bottom of the cylinder (the bottom of the cylinder is rusted and thinned due to contact with moisture, and it cannot withstand the pressure of liquefied gas and leaks).

Try it with a lighter.

If it doesn't explode, it doesn't leak

Apply soapy water to areas where you feel like they might be leaking, if they do, they will bubble :)
