Preferably, the thickness of the tetrafluoro gasket is 3-5mm, and the thickness of the graphite plate is 2.0-3.0 mm.
Preferably, the inner side edge of the graphite plate is 1.8-2.2mm away from the inner side edge of the tetrafluoro gasket body; the distance between the outer side edge of the graphite plate and the outer side edge of the tetrafluoro gasket body is 1.8-2.2 mm.
Preferably, the graphite plate is a pure graphite plate or a metal-reinforced graphite plate.
Preferably, the tetrafluoro gasket body is a pure tetrafluoro gasket body, or a modified polytetrafluoroethylene gasket body, or a tetrafluoro-coated gasket body, or an expanded tetrafluoro gasket body.
According to the technical scheme, the utility model discloses inlay in tetrafluoro gasket body and established the graphite cake. The compression resilience performance preferred of graphite cake, consequently inlay the compression resilience performance also preferred of the tetrafluoro gasket that is equipped with the graphite cake, so the utility model provides a tetrafluoro gasket's sealing performance is with regard to the preferred. The PTFE gasket body has good characteristics of corrosion resistance, ageing resistance and the like. Therefore, the tetrafluoro gasket with the tetrafluoro gasket body also has good characteristics of corrosion resistance, ageing resistance and the like. To sum up, the utility model discloses a tetrafluoro gasket not only has good characteristics such as corrosion-resistant, ageing resistance, but also has good sealing performance.

Wherein, 1 is a tetrafluoro gasket body, and 2 is a graphite plate.
Detailed Description
The utility model discloses a tetrafluoro gasket, this tetrafluoro gasket have the compression resilience performance of preferred to the sealing performance of preferred has.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The utility model discloses a tetrafluoro gasket, this tetrafluoro gasket include tetrafluoro gasket body 1, still include graphite cake 2. The graphite plate 2 is embedded in the tetrafluoro gasket body 1. The graphite plate 2 has better compression resilience, so the tetrafluoro gasket embedded with the graphite plate 2 also has better compression resilience. Therefore, the tetrafluoro gasket of the present invention has excellent sealing performance with respect to a general tetrafluoro gasket. In addition, tetrafluoro gasket body 1 cladding is outside graphite cake 2, because tetrafluoro gasket body 1 has good characteristics such as corrosion-resistant, ageing resistance, consequently the utility model discloses a tetrafluoro gasket also has good characteristics such as corrosion-resistant, ageing resistance. To sum up, the utility model provides a tetrafluoro gasket not only has good characteristics such as corrosion-resistant, ageing resistance, still has the compression resilience performance of preferred.
The utility model provides a tetrafluoro gasket body 1 and graphite cake 2 are the integrated shaping. In particular to the molding by the steps of mould pressing, sintering, drying and the like.
The specific structure of the graphite plate 2 is annular, and the annular graphite plate is surrounded around the center of the tetrafluoro gasket body 1. The more preferable design scheme is that the annular structure of the graphite plate 2 is concentric with the annular structure of the tetrafluoro gasket body 1, so that the graphite plate 2 is positioned at the central position of the annular structure of the tetrafluoro gasket body 1. So set up, when using, the tetrafluoro gasket can provide even resilience in the circumference, so can provide more even sealed.
The thickness of the tetrafluoro spacer may be set at 3-5mm and the thickness of the graphite plate 2 at 2.0-3.0 mm. Further, the distance between the inner side edge of the graphite plate 2 and the inner side edge of the tetrafluoro gasket body 1 is 1.8-2.2 mm. The distance between the outer side edge of the graphite plate 2 and the outer side edge of the tetrafluoro gasket body 1 is 1.8-2.2 mm. By the arrangement, the tetrafluoro gasket can be ensured to have enough resilience, and excellent characteristics such as corrosion resistance and ageing resistance can be ensured.
The stone stilt plate 2 may in particular be a pure graphite plate, a metal-reinforced graphite plate. The pure graphite plate has the characteristics of acid and alkali corrosion resistance, high temperature resistance and the like. The metal reinforced graphite plate has higher structural strength.
The tetrafluoro gasket body 1 is specifically a pure tetrafluoro gasket body, or a modified polytetrafluoroethylene gasket body, or a tetrafluoro-coated gasket body, or an expanded tetrafluoro gasket body.
