After entering the winter, the temperature drops rapidly, and the valve often freezes. If it is not handled at this time, the pipeline is prone to failure. If it is in some high-risk conditions, accidents may also occur. Therefore, Flow Check Valves Factory introduces the anti-freezing techniques of valves:
Before the temperature drops, it is necessary to carry out an all-around heat preservation work on the valve device to make "preparation for winter."
Prepare the necessary tools: insulation cotton, iron wire, vise, utility knife, and carry an effective gas alarm in the gas area.
According to the size of the valve, use a utility knife to cut suitable insulation cotton. Use a vise to cut the wire that needs to be tied up. When wrapping the thermal insulation cotton, tear the thermal insulation cotton a little bit so that it bypasses the valve handle to better wrap the valve body. After wrapping the insulation cotton, fix it with iron wire.
In the process of use, if you find that there is a freezing phenomenon and can not operate normally, do not knock the valve with a wrench or other heavy objects. The correct way is to close the valve, use steam or hot water to thaw the valve before opening 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. Ensuring safe production is an obligation and responsibility of every enterprise. The anti-freezing of valves can be big or small, and we must not cause an irreversible situation because of momentary negligence.
