Copper valve packing maintenance pay attention to what?

Release date:2015-08-07Views:4601

Copper valve packing maintenance

1, packing a direct bearing on whether the key seal leakage occurs when the copper valve switch, if the packing failure, resulting in leakage of the valve is the same failure, especially urea pipeline valves, because a relatively high temperature corrosion comparative interest, packing easy to aging. Strengthen the maintenance can prolong the life of the packing.

2, copper valve at the factory, in order to ensure the elastic filler, generally under static pressure test subject does not leak. After the valve into the pipeline, due to temperature and other factors that may extravasation occur, then we should tighten the timely holding pressure relief valve packing gland nut on both sides, as long as no leakage can later appear extravasation then tight, do not die a tight avoid packing loss of elasticity, loss of sealing performance.

3, some copper valve packing in grease containing molybdenum disulfide, a few months after use, should be added to the appropriate grease, when found in the filler need to be updated, it is timely to increase the appropriate packing to ensure sealing performance. Transmission parts and maintenance NOTE: Copper valves in the switching process, the original grease will be added to the continual loss, coupled with the role of temperature, corrosion and other factors, but also make the lubricating oil constantly dry. Therefore, the valve transmission parts should be regularly checked and found in oil should promptly fill in, to prevent increased wear due to lack of lubricant, causing the drive is not flexible or stuck failure and other failures.
