[China Instrument Network Industry Focus] In the past two days, the small partners in the south of the coordinates should all be concerned about the warning of cooling. It is reported that a strong cold wave will sweep across most of China. Its fierce cooling, the temperature is low, are the strongest this year. In this cold weather, in addition to people need to keep warm, the common water meter gas meters and wire hoses in life have also become very “fragileâ€, and antifreeze work needs to be done in advance.
Natural gas pipelines are seriously affected by freezing. Natural gas contains saturated vapor-phase water and even liquid water. Continuous low-temperature weather will cause gas hydrates to clog valves and pipelines, and users will appear frozen on the gas meter, making it impossible for residents to use gas normally. Some gas company maintenance personnel said that when the situation is serious, it is necessary to handle more than 200 frozen gas meters every day.
What is even more worrying is that there are more serious consequences than the impact on the lives of residents. Natural gas pipelines are prone to flammable explosions after they are unable to transport gas normally. On January 17, after a heavy snowfall in Jilin City, Jilin Province, a large-scale natural gas leak and explosion occurred in a residential area, causing serious losses.
Therefore, it is imperative to do a good job of preventing ice jams. However, we must also remind the residents that when they encounter frozen conditions, they must not dismantle the gas equipment or water the pipes with boiling water, so as to avoid serious consequences. It is the safest practice to seek help in a timely manner and seek professional advice.
The frozen water table is the most vulnerable. During the snowfall in Hangzhou, Zhejiang last week, the water industry group carried out more than 600 repairs, of which more than 95% were repaired due to the surface water pipes and water meters that were broken due to low temperature weather. Case.
This requires real-time monitoring of water pressure at the waterworks and pumping stations to maintain the water pressure within a reasonable range of values. This will ensure that the tap water is delivered to the residents' homes and that the bursting of the water pipes is prevented by the high water pressure.
At the same time, residents can also do antifreeze and warm-keeping measures for water equipment at home. For example, it is necessary to check whether the door of the water meter is closed; at night, close the windows of the kitchen, toilet and shade room to ensure that the room temperature is above 0°C; there is heating in the home and the door leading to the balcony can be opened to ensure the room temperature. Raise the balcony temperature.
Correct "free" and "don't" antifreeze
If it is found that the water pipe in the home has been frozen, the steel pipe can be poured with warm water, especially in the elbow, you can also use a hair dryer to bake, but do not bake at the same point for a long time; aluminum plastic pipe can be wrapped in a towel and slowly Sprinkle with warm water, do not use fire to bake or blanch with boiling water. For exposed water supply pipes, they can be tied with cotton cloth or professional insulation materials and sealed with a plastic film. When the temperature is too low, the faucet in the house can be twisted slightly to make the water flow into a line, which can reduce the degree of freezing of the pipeline and the water meter.
As a precision meter for water, a water meter has its own vulnerability. Therefore, when the meter is subjected to freezing ice, the measures taken must be more careful to prevent damage to the meter.
After the thawed water meter is in use, if there is a clear error indication, Xiao Bian suggests that you have better get the water meter inspection office to carry out inspection and maintenance again to ensure normal use.
If you do not want to be in trouble, Xiao Bian has a more direct approach. At present, there is an anti-freezing water meter on the market. This type of water meter has a very high cold-resistance capacity. Installing such a water meter can prevent the water meter from being frozen to some extent.
Xiao Bian concludes many people are still impressed by the cold weather in southern China in 2008. The snow brought different degrees of disaster to 20 provinces (autonomous regions and municipalities). The freezing rain caused serious road and transmission lines to freeze. Impaired power, train detainment, and other adverse effects. Although this cooling will not be so serious, it still deserves attention. I hope everyone can do a good job of prevention in advance and try to minimize the negative impact of the cold weather on life.
