摘要： A structure of a gland packing box is enhanced in the lubricating function and cooling function of the seal part, by forming at least one disclocating part for partly dislocating in the axial direction a gland packing of the gland packing box. The dislocating part is located on the fitting face of a gland packing holding member for fitting in the axial direction the gland packing externally mounted on a rotary shaft in the packing box. The dislocation causes part of the annular gap formed between the inside of the gland packing holding member and the outside of the rotary shaft to overlap with the internal surface of the gland packing in the circumferential direction, and forces a fluid to be sent into the inner surface of the overlapping gland packing along with rotation of the rotary shaft.
摘要翻译：密封部件的润滑功能和冷却功能增强了压盖包装盒的结构，通过形成至少一个位移部分，以沿轴向部分脱位压盖包装盒的压盖填料。脱位部位于压盖填料保持部件的嵌合面上，用于沿轴向安装在外部安装在包装箱的旋转轴上的压盖填料。位错导致形成在压盖填料保持部件的内部和旋转轴的外侧之间的环状间隙的一部分与压盖密封件的内周面在圆周方向重叠，并迫使流体被送入内部重叠压盖填料的表面以及旋转轴的旋转。

摘要： By improving a metal gasket having a corrugated portion which is advantageous in sealing property, a non-asbestos gasket in which the sealing property is further improved is provided. A non-asbestos gasket has a three-layer structured sealing portion S configured by: a core layer 1A which is made of a plate of a metal, and which is formed into a concentric circle-like corrugated shape; and surface layers 2, 3 which are made of expanded graphite, and which are stacked on the front and back faces of the core layer, respectively. In an outer circumferential end of the sealing portion S, the core layer 1A is protruded from the front and back surface layers 2, 3 toward an outer diameter side. In an inner circumferential end of the sealing portion S, the front and back surface layers 2, 3 are protruded from the core layer 1A toward an inner diameter side, thereby covering the core layer 1A.
摘要翻译：通过改进具有有利于密封性能的波纹部分的金属垫片，提供了进一步提高密封性能的非石棉垫片。非石棉垫片具有三层结构的密封部分S，该三层结构密封部分S由以下部分构成：由金属板制成并形成为同心圆状的波纹形状的芯层1A; 以及由膨胀石墨制成并分别堆叠在芯层的前表面和后表面上的表面层2,3。在密封部S的外周端，芯层1A从前后表面层2,3向外径侧突出。在密封部S的内周端部，前表面层2,3和后表面层2,3从芯层1A向内径侧突出，从而覆盖芯层1A。
