阀门的表面、阀杆和阀杆螺母上的梯形螺纹、阀杆螺母与支架滑动部位以及齿轮、蜗轮蜗杆等部件,容易沾积许多灰尘、油污以及介质残留等赃物,对阀门会产生磨损和腐蚀。
The surface of the valve, the trapezoidal thread on the valve rod and the valve rod nut, the sliding parts of the valve rod nut and the support, as well as the gears, worm gears and other components, are easy to accumulate a lot of dirt such as dust, oil and medium residues, which will cause wear and corrosion to the valve.
因此经常保持阀门外部和活动部位的清洁,保护阀门油漆的完整,显然是十分重要的。阀门上的灰尘适用于毛刷拂扫和压缩空气吹扫;梯形螺纹和齿间的赃物适用于抹布擦洗;阀门上的油污和残留适用于蒸汽吹扫,甚用铜丝刷洗,直加工面、配合面显出金属光泽,油漆面显出油漆本色为止。疏水阀应有专人负责,每班少检查一次,定期打开冲洗阀和疏水阀底的堵头进行冲洗,或定期拆卸冲洗,以免赃物堵塞阀门。
Therefore, it is obviously very important to keep the exterior and moving parts of the valve clean and protect the integrity of the valve paint. The dust on the valve is suitable for brush brushing and compressed air purging; Dirt between trapezoidal threads and teeth is suitable for wiping with rags; The oil stains and residues on the valve are suitable for steam purging, or even brushing with copper wire until the machined surface and mating surface show metallic luster, and the paint surface shows the natural color of paint. The drain valve shall be in the charge of a specially assigned person, and shall be inspected at least once per shift. The flushing valve and the plug at the bottom of the drain valve shall be opened regularly for flushing, or the valve shall be removed and flushed regularly to prevent dirt from blocking the valve.
润滑剂有机油、黄油、二硫化钼和石墨等。高温阀门不适于用机油、黄油,它们会因高温熔化而流失,而适于注入二硫化钼和抹擦石墨粉剂。
Lubricants include engine oil, butter, molybdenum disulfide and graphite. High temperature valves are not suitable for oil and butter, which will be lost due to high temperature melting, but suitable for injecting molybdenum disulfide and wiping graphite powder.
对裸露在外的需要润滑的部位,如梯形螺纹、齿轮等部位,若采用黄油等油脂,容易沾染灰尘,而采用二硫化钼和石墨粉润滑,则不容易沾染灰尘,润滑效果比黄好。石墨粉不容易直接涂抹,可用少许机油或水调合成膏状使用。注油密封的旋塞阀应按照规定时间注油,否则容易磨损和泄漏。
For exposed parts requiring lubrication, such as trapezoidal threads, gears, etc., if grease such as grease 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 that of yellow. Graphite powder is not easy to apply directly. It can be mixed with a little oil or water to form a paste. The plug valve for oil sealing shall be filled with oil at the specified time, otherwise it is easy to wear and leak.
