Pneumatic valve maintenance

for the maintenance of the pneumatic valve, can be divided into two situations; For the custody and use of maintenance.
　　
　　（ A) Improper custody

keeping is one of the important reasons for the damage of pneumatic valve.

pneumatic valve, heap can't disorderly crib, small pneumatic valve on top of the shelf, large pneumatic valve can be lined up on the ground in the warehouse, don't let the flange junction surface contact with the ground. Protect the pneumatic valve is not damaged.

in the short term will not enter the use of pneumatic valve, should remove the asbestos packing, lest produce electrochemical corrosion, damage the pneumatic valve stem.

just into the library for pneumatic valves, check, such as in the process of transportation into the rain water or dirt, try to wipe clean, then to the store.

pneumatic valve import and export with wax paper or plastic seal, in case into the dirt.

to rust in the atmosphere of pneumatic valve machining surface to tu rust-proof oil, to protect it.

placed outdoor pneumatic valves, must cover the linoleum or tarpaulin items such as rain, dust. The warehouse where the pneumatic valve to keep clean and dry.
　　
　　（ 2) Use maintenance

use maintenance is to extend the service life of pneumatic valve and ensure reliable opening and closing.

pneumatic valve stem stem nut thread often and pneumatic friction, with a little butter or graphite powder, lubrication.

don't often open/close the pneumatic valve, turn the handwheel, regularly to the pneumatic valve rod thread to add lubricant, in case of biting.

outdoor pneumatic valves, to the pneumatic valve stem and cases, in case of rain, snow, dust tarnishing.

such as pneumatic valve is a mechanical transmission, to add lubricating oil transmission on time and maintain the cleanness of pneumatic valve.

don't rely on pneumatic valve support other heavy things, don't stand on the pneumatic valve.

pneumatic valve rod, threaded portion, in particular, often should clean and add new lubricant, prevent hard sundries in the dust, wear thread and pneumatic valve rod surface, affect the service life.
