Description
Technical field
The utility model is related to a kind of sealing element, more particularly to a kind of wear-resistant graphite gasket ring.
Background technology
Sealing element is one of the mostly important component that sealing is realized in valve, graphite because with the good coefficient of expansion and
High temperature resistant, high voltage performance, are widely used in the making of valve sealing element.
However graphite material itself is more crisp, brittle, graphite gasket ring is installed in valve and during use, graphite gasket ring
Upper surface and peripheral surface junction corner angle position encounter friction and collision after easily cause abrasion, lead to the sealing of graphite gasket ring
Reduced performance.
Utility model content
The purpose of this utility model is to provide a kind of wear-resistant graphite gasket ring, reduces graphite gasket ring and is installing and using
Abrasion in journey increases the leakproofness of graphite gasket ring.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of wear-resistant graphite gasket ring includes the gasket ring ontology of annular, and the section of the gasket ring ontology is quadrangle, gasket ring
Be enclosed with circular protective cover on the corner angle position of ontology upper surface and peripheral surface junction, gasket ring body peripheral face it is straight
Radially be gradually reduced is in be obliquely installed shape inwardly.
Using the above scheme, graphite gasket ring is wrapped in the protective cover of gasket ring ontology corner angle position during installation and use
Abrasion of the graphite gasket ring in edges and corners can be effectively reduced, reduces the graphite of abrasion as air-flow or liquid enter in equipment and shadow
The operation of equipment is rung, and the diameter in gasket ring body peripheral face is gradually reduced the installation for facilitating graphite gasket ring upwards, reduces graphite pads
Abrasion on ring corner angle and circumferential surface ensure that with this so that the graphite gasket ring being installed in valve body has good integrality
The good sealing performance of graphite pads ring provides good sealing performance for valve body.
Further preferably：The looped wrap that the protective cover is integrally formed, a side flanging and the pad of protective cover
The upper surface of ring body is bonded, and another side flanging of protective cover is bonded with the peripheral surface of gasket ring ontology.
Using the above scheme, protective cover is integrally formed, and avoids the production of connector when protective cover is set on graphite gasket ring
It is raw so that protective cover is wrapped in the flatness of graphite gasket ring edges and corners, increases the protective action to graphite gasket ring.
Further preferably：The protective cover is protective metal shell.
Using the above scheme, metal phase has good wear-resisting property for graphite, while it can bear higher temperature,
When graphite expands, graphite can be carried out the abrasion that package reduces graphite by protective metal shell well, while can also be with valve body
Inner wall be preferably bonded, provide good leakproofness for valve body.
Further preferably：The thickness of the protective cover is 0.3-0.5mm.
Using the above scheme, for the thickness of protective cover in 0.2-0.4mm, protective cover has good protection to gasket ring ontology
Effect, while making protective cover and the spacing in gasket ring body peripheral face smaller, it during expansion can be to gap convenient for gasket ring ontology
It is timely filled so that graphite gasket ring has good sealing performance.
Further preferably：The ratio of the width and gasket ring body peripheral face width of side flanging is outside the protective cover
1:10。
Using the above scheme, the outer side flanging of protective cover and the width ratio in gasket ring body peripheral face are 1:When 10 so that protection
It covers and is reduced as far as possible with the contact area of valve interior wall, reduce the abrasion of protective cover, while gasket ring ontology is played good anti-
Shield acts on.
Further preferably：The angle of inclination of the peripheral surface of the gasket ring ontology is 5-10 °.
Using the above scheme, angle of inclination enables to gasket ring ontology that can quickly be installed in valve body at 5-10 °,
So that the abrasion of gasket ring ontology during the installation process reaches minimum, while ensureing the good sealing performance of gasket ring ontology.
Further preferably：The surface of the gasket ring ontology is provided with wearing layer.
Using the above scheme, wearing layer can increase the wear-resisting property of graphite, reduce graphite gasket ring and installing or using process
In abrasion, extend the usage time of graphite gasket ring.
Further preferably：The wearing layer is alumina ceramic layer.
Using the above scheme, alumina ceramic layer has good wearability, heat-resisting quantity, barotolerance etc., not only increases
The wear-resisting property of cushioning ring body, moreover it is possible to increase the high temperature high voltage resistant performance of gasket ring ontology to a certain extent, and then increase stone
The durability of ink pad ring.
In conclusion the utility model has the advantages that：
1, the utility model is obliquely installed by peripheral surface gasket ring ontology, integrally formed protective cover, effectively reduce stone
Ink pad ring is convenient for graphite gasket ring Fast Installation in valve body so that graphite gasket ring has in the abrasion of edges and corners and peripheral surface
Good integrality provides good sealing performance for valve body；
2, the setting that the utility model passes through wearing layer so that graphite gasket ring has good wear-resisting property, extends stone
The usage time of ink pad ring, and then increase its durable performance.
