Before the temperature drops, it is necessary to carry out a comprehensive insulation work on the valve device to make "winter preparation".

Get the tools you need: thermal cotton, wire, pliers, box cutter, and a valid gas alarm in the gas area.

Use a box cutter to cut the appropriate insulation cotton to the size of the valve.Use pliers to cut the wire for binding.When wrapping the insulated cotton, tear the insulated cotton slightly so that it goes around the valve handle to better wrap the body.After wrapping the insulation cotton, secure it with wire.

If freezing phenomenon is found during the use of the valve, do not use a wrench or other heavy objects to hit the valve.The correct procedure is to close the valve and defrost it with steam or hot water before opening it.

If the valve is not used for a long time, the medium in the pipe should be completely removed to prevent the pipe and valve from freezing.It is the duty and responsibility of every enterprise to ensure production safety.Valve antifreeze this matter, can be big or small, we must not because of a moment of negligence, caused an irreversible situation.
