In winter, the temperature drops rapidly, and the valve often freezes. At this time, if it is not handled, the pipeline will be prone to failure. Accidents may also occur under some high-risk conditions. Therefore, antifreeze treatment of valves is very important.

Prepare the necessary tools: insulation cotton, iron wire, vice, art knife, and carry an effective gas alarm in the gas area.

According to the size of the valve, use a utility knife to cut appropriate insulation cotton. Then use the vice to cut the wire to be bound. When wrapping the insulation cotton, tear the insulation cotton a little to make it bypass the valve handle and better wrap the valve body. After wrapping the insulation cotton, fix it with iron wire.

In the process of use, if it is found that there is freezing phenomenon and it cannot operate normally, it is prohibited to knock the valve with a wrench or other heavy objects. The correct way is to close the valve, defrost the valve with steam or hot water, and then open the valve.
