Replace the gas hose should note the following

(1)hose connection, turn off the Safety Valve, and then using a dedicated gas nozzle joints, then code with throat tightened.
(2) The hose length should be less than 2 meters. Hoses must not produce bend, stretch, foot and so on. Cracked, aging of the hose should not be used.
(3) The hose should not be installed at the following locations: a flame and radiant heat of the place, shelter. Hose, not across the windows, through the use of the house off the wall.
(4) Do not close the hose and the stove. For desktop stove, do not hose or across the disc below, should step aside bypass hose if the next, do not let the flames burn from a height to. Embedded stove, hose not close below the stove. Hoses should naturally droop under cooktop, maintain a distance of more than 10 cm in length should not be more than two meters, to avoid being blown fire burned.
(5) installed hose, soapy water to detect leaks. Open the gas valve switch to see if there is a continuous bubbling, and if so, it indicates that leakage and unsafe.

Total natural gas off only after cooking hobs bad valve does not close.

Total  natural gas valves off only after cooking hobs bad  does not close.
Because when the next total gas valves open when the switch is on the stove, there will be natural gas leak, very dangerous.
After each use of gas stoves, gas imports should turn off valve, then close the valve on the stove.
Suggest:
1, regular checks of gas appliances connected to gas pipeline and hose whether compressed, aging, the interface is loose, whether or rat chewed a sharp object, such as the occurrence of the above phenomenon should immediately contact the gas company.
2, regular replacement hose. According to the gas safety regulations and technical specifications, the hose should be replaced once every two years. Due to the quality of various different hose brand, for the user's own safety, it is recommended to replace the hose once a year, you should consciously do this.

Out, the day forgot to turn off the gas valve how to deal with

General household gas pipeline has three valves, one valve, the second is the conductance valve, the third is gas stove switch. No problem as long as the valve switch, pipes do not leak, theoretically any valve is closed, and will not leak. The reason plus three valves act on multiple insurance. Back to your question, the situation in your home is now only  

gas stove valves

switch is off, in theory, is not airtight. But to be safe, you'd better go home during the day, do not turn on the lights, do not smoke when you entered the room, where there are lights the fire point should be prohibited. After opening the door, the first not to go, stop the door for a while, breathing for a while, whether it can smell the stench? Are chest? Natural gas odorant added to the gas, it is smell, if there is taste, indicating that leak, leave the door way of handling a distance phone call the gas company, called its processing. After processing the doors and windows to ventilate the room are open, natural gas is not toxic, but more people gathered asphyxia anoxia damage.

Gas stove before the valve is generally in what position

Valve is best not to put the cupboard, the Gas Valves pipeline should not be placed in a relatively airtight appliance, reason is flammable and explosive gas valve leak is a very easy device on cabinet leaks do not know gathered to a certain extent it will encounter fire, explosion, a gas pipeline design and installation allowed, unauthorized changes to the individual's own problems not related to the gas supply sector.

Forgot to turn off the gas stove switch, but the gas valve off what are the consequences?

This should be from the gas stove valve in use to distinguish. When not in use under the gas stove in the situation is safe. Because the gas route is to go through the gas valve and then after stoves, if the valve is closed there is no gas stoves through. But if it is the case both eyes kitchen stove is in use and the other of which has a valve opens distinguished. If you are with a stove flame protection device with automatic protection devices because there is no shut-off valve on the side stoves gas leak does not occur. But do not have stoves flameout protection device eyes as with stoves will appear on the right side of the stove cooking, left the stove will always leak phenomenon. This is very dangerous. Even with stoves flameout protection device is not recommended without closing the two valves on the stove. Valves on the stove valves and piping must be closed with the end to ensure safety.

What are the characteristics of gas burners

1 )
High thermal efficiency: can adapt to pressure fluctuations, self-adjusting time with wind (ie the Gas Valves pressure, wind suction once more; small gas pressure, a little wind suction), combustion, high thermal efficiency;
2) Safety: The burner is equipped with a small fire. The boiler starts, the first point of a small fire, when a small fire to normal and stable combustion, automatic control system only open the main gas valve, fuel can enter the boiler normal combustion, deflagration phenomenon does not produce;
3) fuel adaptability: This kind of burner simply replace a few parts can be used in natural gas, liquefied petroleum gas, coal gas, liquefied petroleum gas and other types of mixed gas valve.

After the use of natural gas shut off valve gas stove is not right?

After each use of gas stoves, you should close the valve on the stove, you can not close the gas valve form, but you should always check the connecting hoses to whether there are air leaks between the stove. Identify problems in time. Suggest:
1, regular checks of gas appliances connected to gas pipeline and hose whether compressed, aging, the interface is loose, whether or rat chewed a sharp object, such as the occurrence of the above phenomenon should immediately contact the gas company.

2, regular replacement hose. According to the gas safety regulations and technical specifications, the hose should be replaced once every two years. Due to the quality of various different hose brand, for the user's own safety, it is recommended to replace the hose once a year, you should consciously do this. Hose replacement should note the following:
(1) hose connections, use a dedicated gas nozzle joints, then code with throat tightened.
(2) The hose length should be less than 2 meters. Hoses must not produce bend, stretch, foot and so on. Cracked, aging of the hose should not be used.
 (3) The hose should not be installed at the following locations: a flame and radiant heat of the place, shelter. Hose, not across the windows, through the use of the house off the wall.

Embedded stove, hose not close below the stove. Hoses should naturally droop under cooktop, maintain a distance of more than 10 cm in length should not be more than two meters, to avoid being blown fire burned.
(5) installed hose, soapy water to detect leaks. Open the gas switch, to see if there is a continuous bubble, and if so, it indicates leaks and unsafe.
3, the use of natural gas should be ignited after opening the gas. Not once lit, switch to quickly turn off gas stoves, should not be deflated after ignition. With automatic ignition stove, will promote the switch knob in direction, the direction of rotation indicated by the arrow, the ignition and adjust the flame size.
4, the use of natural gas stove valve. do not stay away from and observe in order to prevent the flames are boiling water overflow interest or blown off. And pay attention to the kitchen ventilation to keep indoor air fresh.
5, after use, pay attention to closed gas stove or water heater switch, while the valve is closed before the table, to ensure safety.
6, in the course of the gas supply in case of sudden interruption of natural gas switch should be closed to prevent air mixing within the conduit. Should resume gas supply in the air inside the tubes before use emissions.
7. Do not store flammable and explosive materials in the installation of gas pipelines and gas facilities in the room.
After 8, stoves and other gas facilities failure, do not disassemble, contact the gas company, the gas company sent specialized personnel for repair.
 9. Do not tied to the gas pipeline pets, rope, wire or hanging objects take, likely to cause loosening occurs at the interface gas pipeline under the action of gravity, causing a gas leak.
 10, installation of indoor gas pipeline facilities, and keep ventilation, maintain good air circulation. Do not rest or sleep during the installation of indoor gas pipeline facilities is prohibited to do the bedroom.
 11, before going to sleep at night, when you go out for a long time or a long time do not use gas, please check the stove valve is closed, and turn off the gas meter valve before the good.

 13, often with soap and water, detergent behind or detergent and other tests indoor gas equipment connectors, switches, hoses and other parts, to see whether the leak, do not use open flame leak.
 14, stove burners perforations often with thin wire to clean, to prevent blockage of tempering.
15, education of children do not play with the valve or gas facility switch on the gas pipeline to avoid damaging the stove or forget to close the valve.
 16, qualified families can be equipped with a small fire extinguisher or a small amount of powder extinguishing agent, to prevent gas accidents.

Natural gas stove inhalation valve to the inside is how it all about?

gas stove valves should be flame protection problems,
First, try to change two batteries, battery power is low can cause suction and

Gas Control Valve

is not maintained, there will be what you said.
Second, adjusting the throttle, to make the middle of the fire burning fire tray flame protection to the needle for the job (that is, the middle of which a non-ignition of the needle)
Third, check the needle flame protection following cable is loose or fall off.

Valves on gas stoves how to adjust

1, the principle of the two intake valves is to control the air volume, helps regulate the fire burning.
2, if you turn off the Gas Cooker valves, there is no air enters the combustion, the flame will be extinguished or incomplete combustion waste gas source.
If the valve is adjusted to the maximum amount of wind caused by bad Assembly source of ignition and gas waste.
3. If a gas stove valves closed an open, because the stove has two hoops, closing and opening a supra a burning situation will arise.
4, adjusting the good will leak but there will be inadequate combustion waste gas source, adjust the flame when you use the color blue fire better.
