The trapezoidal threads, stem nuts, and sliding parts of the support bracket of the Ting Yang brand pneumatic control valve, as well as the bearing parts, gear and worm gear meshing parts, worm gear meshing parts, and other cooperating moving parts, all need to have good lubrication conditions to reduce friction between components and avoid serious wear. Some parts of the pneumatic control valve are specially equipped with oil cups or nozzles. If they are damaged or lost during operation, they need to be repaired and equipped in a timely manner, and the oil circuit should be ensured to be unobstructed. Lubricating parts should be regularly oiled according to specific conditions. Valves that are frequently opened and have high temperatures should be refueled every week to a month; For valves that are not frequently opened and have low temperatures, the refueling cycle can be extended appropriately.

Pneumatic control valve is a type of valve that uses compressed gas as its power source, a cylinder as its actuator, and accessories such as valve positioners, converters, solenoid valves, holding valves, gas storage tanks, and gas filters to drive the valve, achieving on/off or proportional regulation. It receives control signals from industrial automation control systems to adjust various process parameters of pipeline media, such as flow rate, pressure, temperature, and liquid level. The characteristics of pneumatic control valves are simple control, fast response, and inherent safety, without the need for additional explosion-proof measures.

Lubricants include butter, engine oil, disulfide keys, and graphite. High temperature valves are not suitable for using engine oil or butter, as they will melt and lose due to high temperatures. Instead, they should be injected with disulfide keys and wiped with graphite powder. For exposed parts that require lubrication, such as trapezoidal threads, gears, etc., if grease such as butter is used, it is easy to get dirty. However, using disulfide keys and graphite powder for lubrication is less likely to get dirty, and the lubrication effect is much better than butter. Graphite powder is not suitable for direct application and can be mixed with a small amount of engine oil or water to form a paste for use. The oil sealed plug valve needs to be filled with oil according to the specified time, otherwise it is prone to wear and leakage.
