1, the valve should be placed in ventilated and dry inside the chamber, the ends of the valve passage to jam.
2, if the storage time is longer, should be inspected periodically, and regular cleaning and after cleaning to besmear antirust oil.
3, after the installation, we must also regularly check whether the valve and aging degree of normal work.
The main inspection projects include: (
Sealing surface wear.
The stem and stem nut abrasion of trapezoidal thread.
Packing is outdated failure, if any, should be replaced in a timely manner.
Valve repair after assembly, should carry on the sealing performance test.
Valve should also regularly to inject grease inside, can use for longer periods of time, the right and orderly maintenance and maintenance of the valve, valve can make the function of normal and can increase the service life, some things tend to ignore.
First, at the time of injection oil, tend to ignore the quality of the oil, oil quality is very important, some grease is not only the valve without protection, may also have side effects, so in choosing a grease, try to choose better grease.
How much to the injection valve, if less injection, sealing surface due to the lack of lubricant and speed up the wear and tear.
Inject more fat, will cause the valve plug, affect the normal work, but also can cause the waste oil, when to inject grease valve should be according to the different valve size and instructions for injection, can according to the size of the valve size capacity, calculated, then the proper injection.
Second, when to inject grease valve, often ignore the problem of pressure.
When the injection pressure is too low, can lead to seal failure, or pressure is too high, note oil mouth can easily plug.
