During the Spring Festival, the safety of gas use is worrying, and gas safety accidents have entered a period of high incidence, such as the valve is not closed and the hose is falling off. When residents use gas facilities, they tend to ignore some supporting equipment, such as the inspection of pressure reducing valves, self-closing valves, valves in front of stoves, and hose stoves. These neglected equipment often pose potential safety hazards. Gas companies recommend citizens to check frequently.

The pressure reducing valve sealing ring should be changed frequently

Recently, the reporter learned from the gas repair center of the gas company that in recent years, there have been hidden safety hazards in household gas use, and more than 60% of the reasons for safety accidents are caused by the failure of the pressure reducing valve or the loss or damage of the rubber sealing ring. Therefore, it is very important to use the pressure reducing valve correctly. According to the staff of the gas company, when installing the pressure reducing valve, pay attention to the alignment and threading, and then rotate the handwheel in the reverse direction (counterclockwise). "The rubber sealing ring at the intake pipe end of the pressure reducing valve is an important part to prevent gas leakage. Every time the LPG cylinder is replaced, check whether the sealing ring is in good condition. If it is deformed or damaged, it must be replaced."

In addition to the pressure reducing valve, the hose is also an important part of the gas equipment. "Residents came home from get off work and found a smell of coal. After closing the valve, the smell did not dissipate for a long time," a staff member of the gas company said of a case. "We went to the door to check in time and found that the leather pipe was seriously aged, and the gas continued to leak from the cracks. At the same time, it was found that the pressure reducing valve also leaked slightly.” According to professionals, the service life of non-metallic liquefied gas hoses is generally two years, and it is easy to age or even crack after a long time, and it is easy to cause safety hazards such as gas leakage, so Regular inspections and replacements are required, at least every two years. When using non-metallic hoses, there shall be no joints in the middle, and shall not pass through walls, windows and doors. "Because of the low safety factor of rubber hoses, some cities in my country have banned the sale of ordinary hoses and forced the use of metal hoses with a higher safety factor. The price of metal hoses is slightly more expensive than ordinary rubber hoses, but they are safe and reliable. Sex is greatly improved.”

Do not manually switch the self-closing valve

With the Spring Festival approaching, the consumption of natural gas has also reached its peak. Residents in some communities in Gaomi had insufficient natural gas pressure and could not turn on the fire. The gas company reminds: When the pressure is insufficient, residents should not force open the safety self-closing valve of the gas pipeline by themselves. It is best to contact the natural gas company to solve the problem. It is understood that the safety self-closing valve is a valve that automatically closes under abnormal gas supply conditions. It is an automatic protection device and cannot be manually operated as a switch valve. Under normal conditions, the green scale line should be exposed. If there is a gas failure at home, you should first check whether the reset button (black knob on the outside) of the self-closing valve is in the normal position. After the fault is cleared and the gas supply returns to normal, the reset button should be restored to the position of the green scale line before it can be normal. use.

"When the gas consumption peaks, the pressure is relatively low, the flame of the gas stove is not strong enough, and the cooking taste is worse," said Ms. Shan, a citizen. The reporter learned that due to the sharp increase in gas consumption during the heating season, especially at the end of the gas supply pipeline In the community, it is easy to have a situation of insufficient pressure. When the natural gas pressure is insufficient, the safety self-closing valve installed in the household will automatically close. Some residents may forcefully open the self-closing valve and turn on the gas stove at the same time as it is convenient for a while, which will pose a great safety hazard and may cause accidents. Therefore, remind residents that if such a situation occurs at home, it is best to close the safety self-closing valve in the home and contact the gas company as soon as possible to solve it.

After running out of gas, first close the front valve of the stove

According to the staff of the gas company, in addition to the wrong use of the self-closing valve, not closing the valve in front of the stove is also a "common problem" among citizens. The so-called valve in front of the stove refers to the red copper knob under the self-closing valve. The natural gas should be in an upright state during normal use. After use, the valve in front of the stove should be closed in a horizontal direction, and then the valve of the natural gas stove will be closed. Otherwise, it will not burn out. of gas may leak. Since many people do not have the habit of closing the valve in front of the stove after cooking every day, the valve is blocked and difficult to twist. The staff recommends dripping oil for lubrication.

"When using gas, you should pay attention to ventilation, and never close the doors and windows of the kitchen due to the high outdoor temperature. At the same time, someone must take care of you when using gas, so as to prevent the soup from overflowing and extinguishing the flame, or the danger of the flame being blown out by the wind." The staff of the gas company The public is reminded that when using gas appliances, they must be switched off as they are used, especially during holidays, they must carefully check the gas appliances before going out to work, and tell children not to play with the gas appliances.
