After entering winter, the temperature drops rapidly, and the valve often freezes. If this magic is not handled, the pipeline is prone to failure. If it is in some high-risk conditions, accidents may also occur. Therefore, the anti-east treatment of the valve is very important. Before the temperature drops, it is necessary to carry out an all-round thermal insulation work on the valve device to make "winter preparations". Prepare the required tools: thermal insulation cotton, iron wire, vise, utility knife, and carry an effective gas alarm in the gas area. Depending on the size of the valve, use a utility knife to cut the appropriate insulation. Then use the vise to cut the wire that needs to be tied. When wrapping the thermal insulation cotton, tear the thermal insulation cotton a little so that it goes around the valve handle to better wrap the valve body. After wrapping the insulation, secure it with wire. In the process of use, if it is found that there is a phenomenon of freezing and it cannot operate normally, do not hit the valve with a wrench or other heavy objects. The correct way is to close the valve, thaw the valve with steam or hot water, and then open the valve. If the valve is not used for a long time, the medium in the pipeline should be completely removed to prevent the pipeline and valve from freezing.
