For the maintenance of the valve, can be divided into two situations: one is the custody, another is the use of maintenance.
a, custody,
the purpose of custody, is to keep the valve in the custody of the damage, or lower quality.
1。 Valve, should be in good order, small valve on top of the shelf, large valves can be lined up on the ground in the warehouse, not heap crib, don't let the flange junction surface contact with the ground. This not only for beautiful, protects the valve from damaged. To avoid the improper storage and handling as into unnecessary loss.
2。 To not use the valve in the short term, we should remove the asbestos packing, lest produce electrochemical corrosion, damage to the valve stem.
3。 Just into the library for the valve to check, such as in the process of transportation into the rain water or dirt, try to wipe clean, then to the store.
import and export with wax paper or plastic seal, valve into the dirt in case.
4。 To be rusty in the atmosphere valve machining surface to tu rust-proof oil, to protect it.
5。 Placed outside the valve, must cover the linoleum or tarpaulin items such as rain, dust. The warehouse where the valve to keep clean and dry.
(2).
use the purpose of the maintenance in operation and maintenance, is to extend the service life of the valve and assure reliable opening and closing.
1。 Stem thread, often with stem nut friction, to apply p redictors oil, molybdenum disulfide or graphite powder, lubrication.
2。 Don't often open/close the valve, but also to turn the handwheel, regularly add lubricant to the valve stem threads, in case of biting.
3。 Outdoor valves, to be on the valve stem and cases, in case of rain, snow, dust tarnishing.
4。 Such as mechanical valve system to move, to add lubricating oil transmission on time and maintain the cleanness of the valve.
5。 To regularly check and maintain the valve parts integrity. Such as hand wheel fixed nut off, should be used to match neat, can't do, otherwise you will grind garden stem top four sides, gradually lose with reliability, and can't start.
6。 Don't rely on the valve support other heavy things, don't stand on the valve.
7。 Stem, especially the threaded portion, often should clean and add new lubricant, prevent the dust of the hard stuff wear thread and stem surface, affect the service life.
