How to make sure that the gas tank is full of gas, and how to see if the gas tank is still gas

That's the expiration time of the 4-year inspection, and it's safe now; 2.It is the sound of gas flowing when the gas rushes out due to internal pressure, which is normal. Attention should be paid to the usual use:

First, the gas tank should not be placed in a place that is easy to heat up, such as frequent exposure to the sun, and the side of the gas stove (more than a meter away, a little farther away). Second, after use, we must pay attention to close the stove and tank gate valves. Remember!

"Gas tank" is a steel mobile pressure vessel, with the most dangerous, its wall thickness is only about millimeters (the new cylinder factory calibrated wall thickness), unusual, it is always under pressure from the internal medium, normal use of the internal pressure (i.e. pressure) megapascal (5 12 kgf square centimeter), the entire cross-section to withstand about 1000 kg of tension.

The gas tank is injured by collision, exposure and medium corrosion during long-term filling, transportation and use, which will produce fatigue cracks, pits, deformation, corrosion thinning and other defects, which are the direct causes of the accident. Have you ever seen a "gas canister"** scene?

The gas tank will be destroyed twice in an instant, starting with the rupture of the tank body and the physical **, the liquid petroleum gas will instantly expand 250 300 times into a gaseous state, generating a shock wave, like a mine**. The petroleum gas that becomes a gaseous state is quickly mixed with the air, and when the concentration in the air drops to 3 11%, in case of open flame, it will produce chemical **, and the entire gas space ** will burn, producing a huge shock wave, harming lives, burning property, destroying buildings, and bringing secondary disasters.

Starting from the protection of people's lives, the "Regulations on the Safety Supervision of Special Equipment" promulgated by the People's Republic of China lists liquefied petroleum gas cylinders as statutory supervised equipment. "Gas tank" is not a permanent durable product, professional and technical personnel after a large number of accident case analysis and scientific tests, measured the safe use of "gas tank" is only 15 years, during this period every 4 years to carry out a regular inspection, in order to find out the defects, this is the safety guarantee for you and your family, but also the "gas cylinder safety technical supervision regulations" provisions.

At present, the sales price of LPG cylinders on the market is about 100 yuan, which is less than the cost of a shirt. I would like to remind you that when you buy "gas canisters", you have to go to a fixed store, not a free market, where there are many fake and shoddy goods.

Do not sell the cylinders you eliminated as ordinary scrap iron, and do not dispose of them yourself, which is prone to accidents, and send the cylinders to the local Bureau of Quality and Technical Supervision or the boiler and pressure vessel inspection institute for destructive treatment, otherwise, it will fall into the hands of others, may be refurbished, and then flow into the market to harm others.

<> gas is indispensable to us, whether it is for stir-frying in our kitchen or using boiling water for bathing.

help. With the progress of society and economic development, there are generally more people using natural gas now. So how do we determine the amount and surplus of gas?

In fact, there is usually a display on the gas tank, and we only need to check the remaining amount through the indication above. So let's introduce how to check the indicated remaining amount of gas canister.

Method 1: If there is a query button on the table installation, press this button to see it. Or use the gas purchase card to insert the gas meter into the card slot in reverse.

A prompt will be displayed, which can also be seen at this time. If the meter has been powered off, then the meter will not be written after the power is off, because the internal valves will also close at the same time after the motherboard is not working. It will take a few minutes to power it on again, and you will be able to see the remaining amount at this time.

Method 2: If the display value decreases at any time, when the remaining gas volume in the gas meter is low to the alarm gas volume set by the gas company, the gas meter will send an alarm to notify the user to purchase gas, and the LCD screen will be used at the same time.

The alarm number is displayed. If you continue to use the meter until the remaining gas volume in the meter reaches zero, the controller will automatically close the gas meter valve. Only the IC card with the purchased gas capacity can be inserted.

After the gas meter is charged, the gas meter valve can be opened to resume gas supply.

Method 3: Generally, the IC card gas meter has two parts to display, one part is the mechanical counter part, which is the cumulative amount of the gas meter, and the other part is the liquid crystal display.

When an IC card is inserted or a button on the gas meter is pressed, information such as the remaining amount is displayed on the LCD monitor.

The above is the specific solution of how to look at the remaining instructions of the gas canister, I believe you will learn it soon.

There are 3 steps to see if there is gas in the gas tank, which can be judged by the pressure gauge and other aspects. Here are the detailed steps to see if the gas tank is still available:

Steps.

Look at the gas tank pressure gauge.

Look at the pressure gauge on the gas canister, the pointer on it points to red, which means that the gas canister is empty.

Listen to the sound of the gas canister opening.

Turn the switch on and listen for the sound of "sizzling", if the sound becomes weaker, it means that the gas tank is insufficient.

Shake the gas cylinder slightly.

Shake the gas cylinder slightly, whether there is a very liquid flowing sound, the more ** the more the gas is. end

Generally, the household gas tank is filled with about 60 catties of gas.

The empty tank of the household gas tank is 30 catties, and you can fill 24-30 catties to let the limbs gas. According to the national standard, the filling capacity of liquefied gas must reach at least 29 kilograms to be considered sufficient, that is, the weight of the tank is 59 kilograms. Considering the air pressure and other issues, the inflation capacity cannot exceed the standard, with 29 catties as the upper limit.

Generally, the gas canned gas is about 29 kilograms, and the filling weight is 30 kilograms.

Gas Tank (LPG Cylinder):

It is a cylinder for storing gas, the wall thickness of the cylinder is about millimeters, the internal pressure is megatalc Pascal, the safe use period is limited to 15 years, and it needs to be checked regularly every four years.

Methods for identifying if a gas tank is filled with gas:

1. Whether the cover is full or not should be weighed, and there are standards for different cans to be filled.

2. The liquefied gas tank is a storage tank used to store liquefied gas, and the pressure is very high when there is a physical attack on the liquefied gas, and the slightest improper operation may cause **, the pressure of liquefied gas at 20 degrees Celsius is megapascals, and the pressure of 40 degrees Celsius can reach megapascals. The maximum pressure of the liquefied gas cylinder is MPa. If the volume of liquefied gas remains the same, the pressure will increase by megapascals for every 1 degree Celsius increase in temperature, so only 85% of the cylinder can be filled per source, that is, kilograms.

Method: 1. Check the pressure gauge on the gas tank, and there is basically no gas when it reaches red;

2. When you turn on the switch, you will hear a sizzling sound, and the sound will be weaker and there will be less gas;

3. Shake the gas cylinder to see if there is an obvious sound of liquid flowing, the more the sound is, the less gas in it.
