进入冬季以后，气温迅速下降，阀门经常会出现冻结的情况。此时如果不加以处理，管道就很容易出现故障。如果是在一些高危工况，还可能发生事故。因此，阀门的防冻处理是非常重要的。
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.
在气温下降之前，就要对阀门装置进行一次保温工作，做好“过冬准备”。
Before the temperature drops, the valve device shall be insulated to make "winter preparation".
准备好所需工具:保温棉、铁丝、老虎钳、美工刀，在煤气区域还要携带更好的煤气报警器。
Prepare the necessary tools: insulation cotton, iron wire, vice, art knife, and carry a better gas alarm in the gas area.
根据阀门的大小，用美工刀裁剪合适的保温棉。再用老虎钳剪好需要捆绑的铁丝。包保温棉时，将保温棉撕开一点，使之绕过阀门手柄，更好的包裹阀体。包好保温棉后，用铁丝将它固定好。
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.
在使用的过程中如果发现有冻结现象而无法正常运作时，切忌用扳手或其他重物敲击阀门。正确的做法是将阀门关闭，用蒸汽或热水将阀门解冻之后再开启阀门。
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.

长期不使用阀门，应该*排除管道内的介质，防止管道和阀门冻结。保障生产，是每个企业应尽的义务与责任。阀门防冻这件事情，可大可小，我们切不可因为一时的大意疏忽，造成不可挽回的局面。
If the valve is not used for a long time, the medium in the pipeline should be removed to prevent the pipeline and valve from freezing. It is the duty and responsibility of every enterprise to ensure safe production. The valve antifreeze can be either big or small. We must not create an irreparable situation due to temporary carelessness.
