[ Focus on Chemical Machinery and Equipment Network ] The cold wave that has not been encountered for many years has not only made the general public feel cold, but also many water meters and water pipes have also been injured
.
In the face of the cold wave, in addition to people needing to keep warm, the water meters and water pipes that are common in life have become "fragile", and anti-freezing work needs to be done in advance

Water meter, whose foreign name is water meter, is a meter for measuring water flow.
Most of it is the cumulative flow measurement of water.
It is generally divided into two types: volumetric water meter and velocity water meter.
It originated in the United Kingdom.
The development of water meters has a history of nearly 200 years.
, When selecting the water meter specifications, you should first estimate the size and flow range of the flow rate used under normal circumstances, and then select the water meter with the most common flow rate closest to this value as the first choice
.

The cold current is coming and the temperature drops sharply.
In order not to affect the normal water use of the majority of users, please take timely anti-freezing and heat preservation measures for indoor and outdoor tap water facilities.
Outdoor tap water pipes (water meters) can be wrapped with cotton, linen and other fabrics, and doors and windows are closed.
Turn on the water and let the small water flow to prevent it from freezing.
Pay attention to "heat preservation" for the water meter
.

　　The anti-freezing measures of the water meter mainly consist of the following aspects: "Keep dry"
.
Residents of the cottage should pay attention to the dryness in the water meter well and avoid sewage soaking the water supply facilities
.

　　"Close doors and windows"
.
In rooms with water meters and other water supply facilities, close the windows at night to ensure that the indoor temperature is above zero degrees Celsius
.
If water meters and other water supply facilities are installed in the corridor, please pay attention to close the corridor doors and windows
.

　　"Empty the water"
.
When the residents of the bungalow do not use water at night, they must close the water supply valve in front of the water meter in time to drain the water in the pipeline to prevent the water pipe from freezing and cracking
.
If you are away from home for a long time, you can close the valve in front of the water meter before leaving home to drain the water in the pipeline
.

　　"Clothing and wearing a hat"
.
Water supply facilities for water supply pipes, taps, etc.
shall be exposed with scrim, plastic foam, bedding and other insulation materials bandage
.
The outdoor water meter well should be filled with sawdust, cotton wool or other thermal insulation materials, covered with plastic sheet, and the water meter well cover should be covered, which can effectively prevent the water meter and gate valve from freezing
.

Insulation Materials

　　"Warm thaw"
.
For frozen faucets, water meters, and pipes, it is advisable to wrap warm water (not higher than 30 degrees Celsius) on the faucet first, pour it with warm water (not higher than 30 degrees Celsius) to thaw the faucet, then unscrew the faucet, and use warm water to slowly pour the faucet along the faucet.
Pour to thaw the pipe
.
If it is poured to the water meter, there is still no water flowing out, indicating that the water meter has also been frozen.
At this time, wrap the water meter with a hot towel and pour it with warm water to defrost the water meter
.
You can also use a hair dryer to bake and thaw
.
But do not pour it with hot water or bake it with fire, otherwise it will damage the water meter and water pipe
.
Users can store water in advance at night in winter to prevent water inconvenience caused by freezing of water pipes the next morning
.

　　The cold wave that has not been seen for many years has not only made the general public feel cold, but also many water meters and water pipes have also been injured
.
In the face of the cold wave, in addition to people needing to keep warm, common water meters and water pipes in life have become "fragile".
You need to do anti-freezing work in advance, and do you know how to "warm" the water meters?
