摘要
对小机泵（阀）密封装置的基本结构、工作原理进行了较详细的描述，并对软填料的受力、损耗的机理进行了论述，对密封装置的结构提出了改进意见，简述了软填料在使用、更换过程中的注意事项。
To give a detailed description of the structure and operation principle of small pump (valve) sealing device and to discuss the mechanism of applied force and loss of soft packing. On the basis of theoretical analysis, suggestions for improving the structure of the sealing device are made. Meanwhile, points for attention are briefly described about the use and replacement of soft packing. It provides guidance to field application.
