1. The purpose of maintenance is to extend the service life of the fluorine-lined globe valve and to ensure reliable opening and closing.
2. For the fluorine-lined globe valve outdoors, a protective sleeve should be added to the valve stem to prevent rain, snow, dust and rust.
3. The thread of the fluorine-lined globe valve stem often rubs against the stem nut. It is necessary to apply a little yellow dry oil, molybdenum disulfide or graphite powder for lubrication.
4. If the fluorine-lined stop valve is mechanically on standby, add lubricating oil to the gearbox on time.
5. Do not rely on the valve to support other heavy objects, and do not stand on the fluorine-lined globe valve.
7. Always keep the fluorine-lined globe valve clean.
8. Frequently check and maintain the integrity of the other parts of the fluorine-lined globe valve. If the fixing nut of the handwheel falls off, it must be fully equipped and cannot be used properly. Otherwise, it will grind the four sides of the upper part of the valve stem, and gradually lose the reliability of coordination, and even fail to operate.
9. The stem of the fluorine-lined globe valve, especially the threaded part, should be wiped frequently, and the lubricant that has been soiled by dust should be replaced with a new one, because the dust contains hard debris, which is easy to wear the thread and the surface of the stem. Affect the service life.
