copper pneumatic valve packing maintenance and direct relationship between the leakage occurred in the copper pneumatic valve when the switch is the key to seal, if the packing failure, cause leakage, pneumatic valve is equal to failure, especially urea pipe pneumatic valve, due to its high temperature corrosion is interested, packing easy ageing.
Strengthen maintenance can prolong the life of the packing.
, copper pneumatic valve in the factory, in order to ensure the flexibility of the packing, generally will be subject to under the static pressure test does not leak.
Pneumatic valve in pipeline, because of factors such as temperature, extravasation, could occur at this time will be in time to tighten the pressure holding pressure pneumatic valve on both sides of the packing gland nut, as long as where it can, will appear later exosmosis tight again, don't close to death at a time, in order to avoid the packing lose elasticity, loss of sealing performance.
and some copper with mos2 lubricating grease in the pneumatic valve packing, when using a few months later, should be in time to join the corresponding grease, when found the packing need to be supplemented, should increase the corresponding packing in time, in order to ensure the sealing performance.
transmission parts maintenance
note: copper pneumatic valves in the process of switch, the original add lubricating oil will continue to loss, coupled with the role of the factors such as temperature, corrosion, also can make lubricating oil in dry up.
Therefore, the pneumatic valve part should be regularly check, found that the lack of oil should be timely add, just in case because of a lack of lubricant and increase the wear and tear, damage or stuck not flexible transmission failure, etc.
