What to do if that red hat on the switch on the gas falls off?

The red hat on the switch on the natural gas in your home has fallen, so you have to turn off your natural gas meter, otherwise it will run out of gas, in case the cigarette butt slips away, there will be a solid barrier, please go to the person in charge of the natural gas public study in time to come to An. Good.

It doesn't matter if the red hat falls off, there is also an internal valve inside, which can only be unscrewed with a special wrench of natural gas company, or you can install the red hat yourself and press it the notch.

1. Natural gas mainly refers to all gases that naturally exist in nature at present, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (mainly including oilfield gas, gas field gas, mud volcanic gas, coalbed methane and biogenerated gas, etc.). The definition of "natural gas" has long been commonly used, but it is actually a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas.

Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.

2. There will be a red button on the natural gas device, and this red button is not particularly small, so you can clearly see where it is. The natural gas red button is the emergency stop switch, press it to turn off, and unscrew it in a clockwise direction. Basically, we don't need to bother with it anymore, so that it can stay on and make it easier for us to use natural gas.

If you need to go far away, then you need to turn this switch off in case of accidents.

Hello, the red hat on the switch on the gas has fallen off, you can just press it when there is no gas, or you can change the gas canister again.

This red button on the natural gas meter is an emergency button, for example, if you have a gas leak, press it to turn off all the switches.

The red button on the diagram is the valve of natural gas, this red button valve is responsible for whether to draw out the gas, press it to close, there is no natural gas after closing, if you want to connect to natural gas, you press it and there is natural gas.

Uses of Natural Gas:

1. Natural gas can be mainly used for power generation, and the waste emission level of gas turbine power plants fueled by natural gas is much lower than that of coal-fired and oil-fired power plants, and the power generation efficiency is high, the construction cost is low, and the construction speed is fast; In addition, the gas turbine has fast start-stop speed, strong peak regulation capacity, low water consumption, and saves land occupation.

2. The emission levels of carbon monoxide, nitrogen oxides and hydrocarbons of natural gas vehicles are much lower than those of gasoline and diesel engine vehicles, with no carbon deposit, no wear and tear, and very low operating expenses, which is an environmentally friendly vehicle.

3. Natural gas can also be used as a chemical raw material. There are nearly 20 varieties of primary processed products with natural gas as raw material, such as synthetic ammonia, methanol, and carbon black, and more than 50 varieties of important chemical products after secondary or tertiary processing, such as formaldehyde, acetic acid, and dimethyl carbonate. The chemical production plant using natural gas as raw material has low investment, low energy consumption, less land occupation, less personnel, good environmental protection and low operating costs.

4. Natural gas is widely used in civil and commercial gas cookers, water heaters, heating and refrigeration, and is also used in papermaking, metallurgy, quarrying, ceramics, glass and other industries, and can also be used for waste incineration and drying and dehydration treatment.

For gas leakage prevention, if there is a gas leak, it will automatically jump down to prevent natural gas leakage.

This is a safety valve for natural gas.

When there is a leak in natural gas, the valve automatically closes, cutting off the pipeline. To return to normal, you need to press the red button to reset the valve.

Extended Information: In rooms that have been connected to natural gas, users are not allowed to use other fuels, such as bottled liquefied gas.

The length of the natural gas hose should not exceed 2 meters, the rubber hose shall not penetrate the wall and cross the room, and be regularly inspected and replaced, and the hose shall be replaced in time if it is found that the hose is aging, cracked, tortuous or damaged, and it is strictly forbidden to use expired hoses.

Gas appliances must be turned off after each use; It must be confirmed that it is in the closed position before each use before ventilation and ignition.

When cooking, there should be a special person in the kitchen to take care of the soup to prevent the soup from overflowing and extinguishing the fire, which may cause natural gas leakage.

Before going out and going to bed at night, remember to close the valve in front of the gas source stove, and if you don't use the gas appliance for a long time, be sure to close the valve in front of the meter.

In case of sudden interruption of gas supply, the gas appliance switch and the ball valve in front of the stove should be closed at the same time until the normal gas supply is connected, and then it can be continued to be used.

The red button on the natural gas unit is the main valve of the natural gas, which can cut off the pipeline where the natural gas enters by pressing it once, and pressing it again opens the transmission channel and the natural gas can enter again.

Precautions]: When using natural gas, you must ensure that there is no leakage of natural gas, otherwise it is extremely easy to have accidents.

This red button is for the solenoid valve, and its function is to cut off the gas leakage when the gas leaks to avoid further gas leakage.

This should be a solenoid valve, is it energized and the gas leakage alarm system is connected together, if so, it is a safety solenoid valve, when the gas leakage alarm, this is to automatically turn off the gas source.

It should be that the gas alarm triggers the gas shut-off device in other parts at the same time, so as to stop the gas supply.

It is recommended to carefully inspect the entire gas line to see what other valves are connected to the gas alarm. If the gas meter used is a fully automatic electronic meter, the meter itself also has a shutdown function, and the meter needs to be reset.

If you can't handle it well, you should report to the gas company for repair and let it send service personnel to deal with it. Gas-related accidents are very demanding to deal with, and once they are not handled well, they are prone to use hazards.

When gas is detected (the gas concentration is 5% of the lower limit of natural gas, that is, the concentration of natural gas in the air, the * control system inside the sensor and the alarm will issue a "sound and light" alarm command, and the alarm indicator light will brighten up and flash, and send out an intermittent alarm sound. Therefore, it is necessary to install gas alarms, tomorrow and accidents no one knows which will come first, prevention is better than prevention, life is precious, give yourself a safe guarantee for your family. In terms of limit, the general combustible gas is dispersed in the air to the limit range, and it is easy to cause it once there is an open flame ignition.

Therefore, if you look at it from the perspective of leakage, the higher and narrower the lower limit is, the safer it is, and in addition, higher than the upper limit will not. The combustible gas and main components commonly used in life are as follows: Natural gas:

Methane is predominant, ranging from 70%-90% depending on the gas source. Generally speaking, the approximate limit of natural gas ** is 5-15%. Liquefied Gas:

The full name is liquefied petroleum gas, mainly short-chain alkanes, with a small amount of olefins, different batches, different cracking methods, and different oil results. It is generally believed that the limit is in coal gas: carbon monoxide is the mainstay, and water gas will contain a certain proportion of hydrogen, and the content is different in different production methods.

Because it contains carbon monoxide, it is easy to cause carbon monoxide poisoning. Until today, we have never left the car, the equipment, the gas, and the gas industry."

I hope mine can help you.

How to use:

When using, use.

The user will insert the card into the card table (note: insert the card direction, open the battery box cover, require the chip side of the card to face up, insert it vertically, and then pull out the card after the LCD screen displays the number), and the gas purchase amount in the card is automatically entered into the table.

Red buttons:

The switch, the handle is open parallel to the organ, and the tube is closed at a right angle of 90 degrees.

Green handle switch:

It's a pressure valve, don't worry about it, just connect the gas pipe of the gas stove directly.

Natural gas]: 1, the definition of "natural gas" that has been commonly used for a long time is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.

2. The main use of natural gas is as fuel, which can make carbon black, chemicals and liquefied petroleum gas, and propane and butane produced by natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low-molecular-weight hydrocarbons and non-hydrocarbon gases.

3. Natural gas is a general term for the mixed gas with hydrocarbons as the main body in the underground rock reservoir, with a specific gravity of about that, lighter than air, and colorless, tasteless and non-toxic.

The main components of natural gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane and butane, in addition to hydrogen sulfide, carbon dioxide, nitrogen and water vapor and a small amount of carbon monoxide and trace amounts of rare gases, such as helium and argon. Before the natural gas is delivered to the end user, in order to help with leak detection, mercaptans, tetrahydrothiophene, etc. are used to add odors to the natural gas.

4. Natural gas is one of the safer gases, it does not contain carbon monoxide, and it is lighter than air, once it leaks, it will immediately diffuse upward, and it is not easy to accumulate to form ** gas, and the safety is relatively higher than that of other combustion gases.

5. Natural gas can suffocate people after the content in the air reaches a certain level. Natural gas is not as toxic as carbon monoxide, and it is inherently harmless to humans. However, if natural gas is in a state of high concentration and the oxygen in the air is not enough to sustain life, it can still cause death, after all, natural gas cannot be used for human breathing.

As a fuel, natural gas can also be caused by the occurrence of **.

The top handle is the switch, the handle is parallel to the organ is open, and the tube is closed at a right angle of 90 degrees, the machine below is the gas meter, the gas meter is linked to the wiring is an automatic gas flu switch, that is to say, you usually do not need to open and close the gate, as long as you turn on the switch on the gas stove, this small switch will automatically open when it senses the flow of gas, on the contrary, you turn off the gas stove switch and automatically close it without gas flow, this does not care about it is automatic, the second picture below is a pressure valve, Leave it to chance, just connect the gas pipe of the gas stove to it.

The green handle is an ordinary gas valve, straight line and 90 degrees are switches, the principle and tap water valve should be similar, it is estimated that there is a difference in sealing and safety, and gas is more required to be safe.

The red button is an emergency shut-off solenoid valve, which is different from the common red emergency switch that controls electricity, and the electrical appliance is pressed to cut off the power urgently. The gas is the upper left safety detection device detects gas leakage, fire and other dangerous and unexpected situations, automatically controls the solenoid valve to turn off the gas, opens the protective cover when it returns to normal, and presses the red button to resume the gas opening.

The emergency shut-off device also uses a motor to close the upper lever valve, but the solenoid valve is more agile and safer.

This is not an alarm, this is a gas leak-proof self-closing valve.

Gas alarms generally look like this, the white object on the right side of the picture below. The connection between the gas alarm and the leak-proof self-closing valve should be connected together.

The alarm is generally connected to electricity, and after sensing the leakage of combustible gas (natural gas, liquefied gas, coal gas, biogas, etc.) in the room, or emitting an alarm sound, and automatically closing the leak-proof self-closing valve.

After eliminating the danger that there is no combustible gas in the room, the gas alarm will stop the alarm, and then manually pull out the red button to restore the gas supply.

In addition: this connection is more dangerous, there should be a self-closing valve (both pressure regulation) before the yellow knob switch, if the gas pressure is too large or too small will cause the self-closing valve to close, and the leak-proof self-closing valve above will not close.

The natural gas alarm can be installed on the gas pipeline, the red button is the solenoid valve, when there is a gas leakage, it will automatically cut off the gas, and lift it when the ventilation is restored.
