Reducing valve hose stove hidden danger of residents should be diligent in checking

When residents use gas facilities, they often neglect the inspection of some auxiliary equipment such as pressure relief valves, hoses, and stoves. These neglected devices are likely to become invisible killers and pose hidden dangers for safe use of gas.

The author recently learned from the gas company's gas repair center that from January to July this year, the emergency repair center issued a total of 298 police officers to provide assistance for bottled liquefied petroleum gas users. Among them, the user's pressure relief valve leaks, there is no washer, gasket leakage 88, the user's skin leaks, blocked 63. There are also some residents who have used stoves that have exceeded the national deadline for scrapping, and there are also many potential safety hazards.

Last Saturday, there was a gas accident caused by the leakage of a pressure relief valve at 68 Giganton Street. A resident found a gas leak in his home and immediately alerted him after closing the valve. After inspection of the gas 110 door, it was found that the user of the liquefied gas valve had a problem. Fortunately, it was discovered in a timely manner that it did not cause disaster.

More than 60% of the poisoning and explosion accidents that occurred in the past were caused by the lack of pressure relief valves or the loss or damage of rubber seals. Therefore, it is very important to use the pressure reducing valve correctly.

When installing the pressure reducing valve, pay attention to aligning and aligning the screw thread, and then rotate the hand wheel in the counterclockwise direction (counterclockwise direction). The rubber seal on the intake pipe end of the pressure relief valve is an important part to prevent air leakage. Every time the LPG cylinder is replaced, the seal should be checked for its integrity. If it is deformed or damaged, it must be replaced.

In addition to pressure relief valves, hoses are also an important part of gas equipment. On the morning of July 4th, a resident of Mojiaxiang reported that he had a heavy gas smell in his home. After the valve was closed, the flavor had not been dispersed for a long time. After the gas 110 received the alarm, it was checked on the door and it was found that the skin tube was seriously aged and the gas leaked out from the crack. At the same time, there was also a slight leak of the pressure reducing valve. It has been speculated that the user's skin tube took at least 5 years.

According to professionals, non-metallic materials of liquefied gas hose life is generally two years, a long time easy to aging or even cracking, easy to produce gas leaks and other hidden dangers, so regular inspection and replacement, at least two years to replace once. The use of non-metallic hoses must not have an interface, not through the walls, windows and doors. Due to the low safety factor of rubber hoses, some cities in China have already stipulated the prohibition of the sale of ordinary hoses, and forced the use of metal hoses with high safety factors. Metal hoses are slightly more expensive than general rubber hoses, but their safety and reliability are greatly improved.

In addition, the user who uses the embedded gas cooker must pay attention to checking whether the cooker has an automatic flameout protection device and pay attention to the service life. When the gas cooker with automatic flameout protection device is accidentally extinguished in the flame of the burner, the flameout protection device can cut off the gas supply in time so as to avoid the risk of gas leakage. China has always had mandatory requirements for the automatic flameout protection function of embedded gas cookers, but there are still some manufacturers' products that do not meet the standards. Residents must be careful when shopping for cooking appliances. Do not buy cooking appliances without automatic flameout protection. For stoves that have passed the 8 year limit, they should be replaced as soon as possible.
