Abstract
The utility model relates to a wear-resistant graphite packing ring, which comprises a ring-shaped packing ring body. The packing ring body is provided with an inner circumferential surface, an outer circumferential surface, an upper end face and a lower end face. The wear-resistant graphite packing ring is characterized in that at least one of a combination part of the outer circumferential surface and the upper end face of the packing ring body and a combination part of the outer circumferential surface and the lower end face of the packing ring body is provided with a wear-resistant ring. Compared with the prior art, the wear-resistant graphite packing ring has the advantages that due to the arrangement of the wear-resistant ring, wear of edges and corners of the graphite packing ring in friction and collision processes can be reduced, the rate of leakage can be decreased, and the service life of the graphite packing ring can be prolonged.
Description
Technical field
The utility model relates to a kind of sealing carbon packing ring, belongs to the Sealing technical field.
Background technique
Carbon packing ring is applicable to the mechanical seal of the industries such as oil, chemical industry, generating, can be used for sealing medium.The quality of evaluating graphite packing ring is to use sealing to be as the criterion.Common graphite packing has inner peripheral surface, outer circumferential face, upper-end surface and lower end surface in the form of a ring, by pure flexible graphite paper, after shearing, in mould graphite paper is twined the ring-type graphite packing that compacting forms through spirality.General section is square, also can be that wherein an end face is the v-shaped structure of the conical surface.It can referenced patent number be the Chinese utility model patent " expanded graphite packing ring " (notice of authorization number be CN202056304U) of ZL201120186863.4.
Graphite material itself is more crisp, frangible, moreover, two corner angle positions of the upper-end surface of carbon packing ring and outer circumferential face connecting part and lower end surface and outer circumferential face connecting part easily cause wearing and tearing run into friction and collision in installation and using process after, cause sealing to reduce, cause leakage, be necessary the wear resistance of the corner of carbon packing ring is improved for this reason, thereby the reduction leakage probability, and then improve its working life.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of wear-resisting carbon packing ring for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of wear-resisting carbon packing ring, comprise packing ring body in the form of a ring, this packing ring body has inner peripheral surface, outer circumferential face, upper-end surface and lower end surface, and the connecting part that it is characterized in that the connecting part of described packing ring body outer circumferential face and upper-end surface and outer circumferential face and lower end surface has one of at least wear ring.
The cross section of described packing ring body can be rectangle, also can be that described packing ring body upper-end surface is that the conical surface forms V-arrangement.
As preferably, the connecting part of the outer circumferential face of described packing ring body and the connecting part of upper-end surface and outer circumferential face and lower end surface all has wear ring.
As preferably, described wear ring is spiral helicine steel wire ring.Because the steel wire ring inner hollow has the gap, graphite packing can fill, and helps the combination of steel wire ring and packing ring body.Can certainly adopt other wear-resisting ring structures, as abrasion resistant fibrous, abrasive rubber etc.
As preferably, the exterior edge face of described steel wire ring flushes with the outer circumferential face of packing ring body.
The upper-end surface of described steel wire ring flushes with the upper-end surface of packing ring body, or the lower end surface of described steel wire ring flushes with the lower end surface of packing ring body.
Institute's steel wire ring and graphite packing take shape in one in mould inner pressure system.Graphite packing is penetrated in the gap of steel wire ring hollow, in conjunction with close and firm more.
Compared with prior art, the utility model has the advantage of: because the existence of wear ring, the wearing and tearing in friction and collision process of the edge of carbon packing ring are less, thereby leak-down rate reduces, and then improved its working life.
Description of drawings
Fig. 1 is the example structure schematic diagram.
Fig. 2 is the structural representation of steel wire ring among Fig. 1.
Fig. 3 is embodiment's partial sectional view.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, wear-resisting carbon packing ring in the present embodiment comprises packing ring body 1 in the form of a ring, this packing ring body 1 has inner peripheral surface 12, outer circumferential face 13, upper-end surface 11 and lower end surface (nothing illustrates among the figure), and the outer circumferential face 13 of packing ring body 1 all has wear ring 2 with the connecting part of 11 connecting parts, upper-end surface and outer circumferential face 13 and lower end surface.
In conjunction with shown in Figure 3, the cross section of the packing ring body 1 in the present embodiment is rectangle, also can be that packing ring body upper-end surface is that the conical surface forms V-arrangement.
Wear ring 2 in the present embodiment is spiral helicine steel wire ring.The exterior edge face of two steel wire rings all flushes with the outer circumferential face 13 of packing ring body 1.Above the upper-end surface of a steel wire ring flush with the upper-end surface 11 of packing ring body, below the lower end surface of a steel wire ring flush with the lower end surface of packing ring body.
With reference to shown in Figure 3, steel wire ring and graphite packing take shape in one in mould inner pressure system again.Graphite packing is penetrated into steel wire ring inside, in conjunction with close and firm more.
Because steel wire ring firmly is combined on the corner of packing ring body, the wearing and tearing in friction and collision process of the edge of carbon packing ring are less like this, thereby leak-down rate reduces, and then improved its working life.
