TALK ABOUT THE LUBRICATION WORK OF THE VALVE

We are a gate valves manufacturer, and ball valves is one of our products. Let us give you a popular knowledge of valve lubrication.

The trapezoidal thread of the valve, the sliding part of the valve stem nut and the bracket, the bearing part, the meshing part of the gear and the worm gear, the worm screw, and other cooperating parts all need good lubrication conditions to reduce mutual friction and avoid mutual wear. Some parts are specially equipped with oil cups or oil nozzles. If they are damaged or lost during operation, they should be repaired and arranged, and the oil circuit should be cleared.

Lubrication parts should be refueled regularly according to specific conditions. Valves that are opened frequently and the filter temperature is high are suitable for refueling once every one week to a month. Valves that are not opened frequently and the temperature are not high can have a longer refueling cycle. Lubricants include organic oils, butter, molybdenum disulfide and graphite, etc. High temperature valves are not suitable for oil and butter, which will be lost due to high temperature melting, but are suitable for injecting molybdenum disulfide and wiping graphite powder. For exposed parts that need to be lubricated, such as trapezoidal threads, gears, etc., if grease such as butter is used, it is easy to be contaminated with dust, while molybdenum disulfide and graphite powder are used for lubrication, it is not easy to be contaminated with dust, and the lubrication effect is better than butter. Graphite powder is not easy to apply directly, it can be used with a little oil or water. The plug valve with oil filling and sealing should be filled with oil according to the specified time, otherwise it is easy to wear and leak.
