Abstract
The utility model discloses a kind of reinforced graphite seal ring, be made up of multilayer coating structure layer and graphite layer, described clad and graphite layers are every setting, described clad is provided with multiple polygonal coupling hole, described attachment hole is provided with hangnail, described hangnail one end connects clad, and the other end embeds in graphite layer.Achieve the connection between clad and graphite layer by stamping forming hangnail in sealing ring, and by hangnail, graphite layer is fixed, prevent from skidding between layers, improve the sealing reliability of seal ring.
Description
Technical field
The utility model relates to valve seal technical field, particularly a kind of reinforced graphite seal ring.
Background technique
Be arranged on the characteristic that the steam line of power station or the ducted valve of petroleum chemical industry poisonous gas all have himself, the steam line in thermal power plant is mainly drawn from turbine body or boiler-steam dome, therefore has the extreme damage of High Temperature and steam water two phase flow; And in chemical industry poisonous gas pipeline, sealingly secure is most important equally.Seal ring, as the important component part sealed in valve glue container class equipment, has more and more higher requirement to the performance of seal ring.The material being commonly used to mechanical seal ring at present mostly adopts graphite material, it has good self-lubricating property, and friction factor is low, excellent anti-corrosion performance, heat-conducting property is excellent, linear expansion coeffcient is low, and the excellent and easy feature such as processing of heat resistance, but, the seal ring made with graphite material but has a fatal weakness, that is that mechanical strength is very low with regard to it, very fragile, very easily embrittlement and cracked under uneven pressure.Therefore, usually need to add graphite fiber or wire in graphite to improve its mechanical property, but because graphite cross-section size is comparatively large in this seal ring, make to be in best anti-yield situation during its work, because face integrity is poor, the life-span is very short.
Model utility content
The utility model solves the problem that above-mentioned graphite connects between layers, provides a kind of structure simple, manufactures reinforced graphite seal ring easy to process.
For solving the problems of the technologies described above, the utility model have employed a kind of reinforced graphite seal ring, be made up of multilayer coating structure layer and graphite layer, described clad and graphite layers are every setting, described clad is provided with multiple attachment hole, described attachment hole is provided with hangnail, and described hangnail one end connects clad, and the other end embeds in graphite layer.
Further, in the utility model, the hangnail of described clad last point of attachment hole is positioned at the left side of clad, and another part is positioned on the right side of clad.
Further, in the utility model, described attachment hole is circular.
Further, in the utility model, described attachment hole is triangle.
Further, in the utility model, described hangnail passes through impact briquetting.
Further, in the utility model, described clad adopts Thin Stainless Steel steel plate.
Further, in the utility model, described coating thickness is 0.03 ~ 0.05mm, and described graphite layer thickness is 0.7 ~ 1.2mm.
Further, in the utility model, on described attachment hole, hangnail height H is 0.45mm.
The beneficial effect that the utility model has:
1, multi-layer combined type structure is adopted, easy to process, and improve the overall mechanical strength of seal ring.
2, realize the connection between clad and graphite layer by stamping forming hangnail, and by hangnail, graphite layer is fixed, achieve the integrity being increased each several part by external force constraint, improve the sealing reliability of seal ring.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 4 is clad and graphite layer linkage structure partial schematic diagram in Fig. 3.
In figure: 1, seal ring, 2, attachment hole, 3, clad, 4, graphite layer, 5, hangnail, H, hangnail height.
Embodiment
Referring to figs. 1 through 4, for a kind of reinforced graphite seal ring, sealing ring 1 is made up of multilayer coating structure layer 3 and graphite layer 4, clad 3 and graphite layer 4 interval are arranged, clad 3 is provided with multiple attachment hole 2, attachment hole 2 is provided with hangnail 5, hangnail 5 one end connects clad 3, and the other end embeds in graphite layer 4.
In the utility model, the hangnail 5 of clad 3 last points of attachment holes 2 is positioned at the left side of clad 3, another part is positioned on the right side of clad 3, the graphite layer 4 adjacent with these clad 3 both sides makes clad 3 be connected with the graphite layer 4 of both sides by the hangnail 5 of clad 3 both sides, and the graphite layer 4 of both sides is fixed by the hangnail 5 of clad 3.
Embodiment one: as shown in Figure 1, and in the utility model, attachment hole 2 adopts round structure.
Embodiment two: as shown in Figure 2, and in the utility model, attachment hole 2 adopts equilateral triangle structure.
Hangnail 5 on clad 3 described in the utility model passes through impact briquetting, in impact briquetting process, the connection hole flange of clad 3 forms hangnail 5, and hangnail 5 is under certain effect power, embed in graphite layer 4, thus by hangnail 5, clad 3 is connected with graphite layer 4.
Clad 3 in described seal ring 1 adopts 316 sheet metals of 0.03 ~ 0.05mm, and described graphite layer 4 thickness is 0.7 ~ 1.2mm; On described attachment hole, hangnail height H is 0.45mm.
In seal ring 1 described in the utility model, graphite layer 4 thickness is 0.05mm, and clad 3 thickness is 1.15mm, successively superposes by graphite layer 4 and clad 3 interval the graphite-seal ring 1 that composition thickness is 16mm.
The utility model is not limited to above-described embodiment; on the basis of technological scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some of them technical characteristics to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
