Abstract
The invention discloses an enhanced graphitic sealing ring. The enhanced graphitic sealing ring is composed of a plurality of coating layers and graphitic layers, wherein the coating layers and the graphitic layers are arranged at intervals; a plurality of polygonal connecting holes are formed in each coating layer; a barb is arranged on each connecting hole; one end of each barb is connected with the corresponding coating layer, and the other end of each barb is embedded into the corresponding graphitic layer. According to the sealing ring, each coating layer can be connected with the corresponding graphite layer through the corresponding barbs which are formed by punching, the graphitic layers are fixed through the barbs, slipping between the layers is prevented, and the sealing reliability of the sealing ring is improved.
Description
Technical field
The present invention 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.
Summary of the invention
The invention solves the problem that above-mentioned graphite connects between layers, provide a kind of structure simple, manufacture reinforced graphite seal ring easy to process.
For solving the problems of the technologies described above, present invention employs 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 present invention, 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 present invention, described attachment hole is circular.
Further, in the present invention, described attachment hole is triangle.
Further, in the present invention, described hangnail passes through impact briquetting.
Further, in the present invention, described clad adopts Thin Stainless Steel steel plate.
Further, in the present invention, described coating thickness is 0.03 ~ 0.05mm, and described graphite layer thickness is 0.7 ~ 1.2mm.
Further, in the present invention, on described attachment hole, hangnail height H is 0.45mm.
The beneficial effect that the present invention 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.

Fig. 2 is the embodiment of the present invention one structural front view.
Fig. 3 is structure sectional view of the present invention.
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 present invention, 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 present invention, attachment hole 2 adopts round structure.
Embodiment two: as shown in Figure 2, and in the present invention, attachment hole 2 adopts equilateral triangle structure.
Hangnail 5 on clad 3 described in the present invention 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 of the present invention, 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 present invention is not limited to above-described embodiment; on the basis of technological scheme disclosed by the invention; 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 scope of the present invention.
