Fig. 3 be embodiment illustrated in fig. 1 in the schematic representation of inside and outside seal ring.
Fig. 4 be embodiment illustrated in fig. 1 in the schematic representation of stacked seal ring.
[embodiment]
See also Fig. 1 and Fig. 2, it is a preferred embodiment of the present invention, dynamic seal apparatus of the present invention is installed between rotating shaft 100 and the casing 200, and is sheathed in the rotating shaft 100, and it comprises a pedestal 1, seal ring group, spring ring 2, adjusts packing ring 3, spring washer 4 and pressing plate 5.
Described pedestal 1 in the form of a ring, its exterior edge face caves inward and forms a cavity 12, described seal ring group, spring ring 2, adjusts packing ring 3, spring washer 4 and pressing plate 5 and all is installed in the cavity 12 of pedestal 1.In the outermost end of pedestal 1, promptly cavity 12 opening ends are provided with an annular groove (not indicating among the figure), and described pressing plate 5 is arranged in described annular groove.Described adjustment packing ring 3 and spring washer 4 wherein, adjust the exterior edge face that packing ring 3 is stacked and placed on the seal ring group, and spring washer 4 are stacked and placed on the exterior edge face of adjusting packing ring 3 between pressing plate 5 and seal ring group.
Described seal ring group comprises along radially inside and outside inner seal ring 6, the outer seal ring 7 that is provided with of rotating shaft 100, and the stacked seal ring 8 that axially is stacked and placed on inside and outside seal ring 6,7 exterior edge faces along rotating shaft 100.
The internal diameter of described inner seal ring 6 is corresponding with the diameter of rotating shaft 100, and described outer seal ring 7 is sheathed on the outer rim of inner seal ring 6, and its internal diameter is corresponding with the external diameter of inner seal ring 6.Please together consult Fig. 3, on described inside and outside seal ring 6,7, along the circumferential direction be evenly equipped with a plurality of flutings 62,72 respectively, described fluting 62,72 is respectively through between the inside and outside footpath of inside and outside seal ring 6,7, thereby inside and outside seal ring 6,7 can be moved radially, changing the requirement that cooperates of its internal diameter and rotating shaft 100, thereby reach the purpose of sealing.In order to prevent that liquid from outwards flowing out along fluting 62,72, influence sealability, 62,72 the position of slotting on the inside and outside seal ring 6,7 is interlaced along circumference, thereby makes the mobile of liquid become difficult, even can not flow.
Described stacked seal ring 8 can further improve airtight quality, and it has further limited flowing of liquid.Please together consult Fig. 4, the internal diameter of described stacked seal ring 8 is corresponding with rotating shaft 100 diameters, along the circumferential direction also offer a plurality of flutings 82 on it, described fluting 82 is also through between the inside and outside footpath of stacked seal ring 8, and the position of fluting 72 is corresponding on its position and the outer seal ring 7.
Be inserted with a guide finger 9,10 in the fluting 62,72 of described inside and outside seal ring 6,7 respectively, one end of described guide finger 9,10 is fixed on the pedestal 1, wherein, the guide finger 10 that is inserted in outer seal ring 7 flutings 72 also is inserted in the fluting 82 of stacked seal ring 8, thereby each seal ring is positioned and channeling direction.
Outer edge surface in described outer seal ring 7 and stacked seal ring 8 along the circumferential direction offers a groove (not indicating among the figure) respectively, described spring ring 2 is sheathed in the described groove, described spring ring 2 can make each seal ring remain contact condition with rotating shaft 100 and liquid, and moving radially of each seal ring makes liquid seal in casing 200.
Dynamic seal apparatus of the present invention is when work, inside and outside seal ring 6,7 and stacked seal ring 8 keep in touch, seal with rotating shaft 100 tightly under the effect of spring ring 2, wherein, inner seal ring 6 keeps sealing with rotating shaft 100 under the radial effect of outer seal ring 7; And spring washer 4 makes adjustment packing ring 3, stacked seal ring 8, outer seal ring 7, inner seal ring 6 eliminate axial clearances, keep sealing.Can retainer shaft when the inside and outside seal ring 6,7 of dynamic seal apparatus of the present invention and stacked seal ring 8 are in running order to move radially, they can be with rotating shaft 100 free floatings, therefore, the working life of dynamic seal apparatus of the present invention is higher, sealability is better, especially is fit to be installed in the relatively harsher place of higher seal request, environment.Above-mentioned seal ring group can select for use graphite material to make, thereby brings into play the characteristics that graphite material is wear-resistant, greasy property is good well.
As other mode of executions of the present invention, the quantity of slotting on each seal ring of the present invention can be provided with more than one according to actual use occasion, in the above-described embodiments, three flutings is set preferably on each seal ring.
