Description

Technical Field

[0001] The present application relates to the technical field of graphite composite gaskets, and in particular to a novel graphite composite gasket. Background Art

[0002] Gaskets are materials used to strengthen the seal between two planes. Through mechanical sealing between two objects, they are used to prevent leakage caused by pressure, corrosion, and natural thermal expansion and contraction of the pipeline. Graphite gaskets are cut or stamped from pure graphite plates or metal-reinforced graphite plates. They have many excellent sealing properties and can be used stably and for a long time under harsh working conditions.

[0003] Graphite composite gasket is also called flexible graphite metal reinforced composite gasket or high-strength graphite gasket. It is a sealing gasket made of a punched metal tooth plate or a punched metal core plate and flexible graphite particles. It is usually made of a flexible graphite composite reinforced plate.

[0004] The existing graphite composite gasket has a mounting hole on its exterior so that the graphite composite gasket can be installed between two objects.

[0005] In the process of implementing the present application, at least the following problems exist in the prior art. For example, the existing graphite composite gasket mounting holes are usually fixed holes, and the holes are arranged at equal intervals. This means that when installing the graphite composite gasket, the mounting holes between the two objects must be aligned to fix the graphite composite gasket. This method is not only cumbersome to operate, but also inefficient, which increases the installation time of the graphite composite gasket. Therefore, a new type of graphite composite gasket is proposed to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present application provides a new type of graphite composite gasket, which has the advantages of strong practicality and easy installation, and solves the problem that the graphite composite gasket must be aligned with the installation hole between two objects before it can be installed.

[0007] In summary, the present application provides the following technical solutions: a novel graphite composite gasket, comprising a graphite composite gasket body, wherein the graphite composite gasket body has an annular mounting opening communicating with upper and lower sides;

[0008] The graphite composite gasket body comprises a heat-conducting braided layer, a graphene layer, a first air-permeable layer, a second air-permeable layer, a flame-retardant layer, an anti-oxidation layer, a first wear-resistant layer and a second wear-resistant layer.

[0009] By adopting the above-mentioned technical solution, the present application facilitates the staff to calibrate the graphite composite gasket body with the mounting hole between two objects when installing it, and it can be installed without adjusting the graphite composite gasket body, which greatly improves the installation efficiency of the graphite composite gasket body, thereby achieving the advantages of strong practicality and easy installation, and effectively solves the problem that the graphite composite gasket must be aligned with the mounting hole between two objects before it can be installed.

[0010] Furthermore, the thermally conductive braided layer is located in the middle, the number of the graphene layers is two, and the two graphene layers are located on both sides of the thermally conductive braided layer.

[0011] The beneficial effect of adopting the above further solution is that the thermal conductivity of the graphite composite gasket body is improved by the two graphene layers.

[0012] Furthermore, the first air permeable layer and the second air permeable layer are respectively connected to one side of the two graphene layers that are separated from each other.

[0013] The beneficial effect of adopting the above further solution is that the heat of the graphite composite gasket body can be quickly dissipated through the installation of the first air permeable layer and the second air permeable layer.

[0014] Furthermore, the flame retardant layer is fixedly connected to a side of the first air permeable layer away from one of the graphene layers, and the first wear-resistant layer is connected to the other side of the flame retardant layer.

[0015] The beneficial effect of adopting the above further scheme is: by installing the flame retardant layer, the graphite composite gasket body can be protected, and the flame retardant layer makes the graphite composite gasket body have a flame retardant effect. At the same time, the first wear-resistant layer and the second wear-resistant layer make the graphite composite gasket body more wear-resistant and not easy to be damaged. The second wear-resistant layer further enhances the wear resistance of the graphite composite gasket body.

[0016] Furthermore, the second breathable layer is connected between the anti-oxidation layer and another graphene layer, the second wear-resistant layer is connected to the outermost side of the anti-oxidation layer, the first breathable layer and the second breathable layer have the same specifications, and pores are provided on the surfaces of the first breathable layer and the second breathable layer.

[0017] The beneficial effect of adopting the above further solution is that heat can be dissipated from the air holes opened on the surfaces of the first air permeable layer and the second air permeable layer, and the graphite composite gasket body is not easily oxidized by the anti-oxidation layer.

[0018] Furthermore, a through hole communicating with the outside is provided in the middle of the graphite composite gasket body, and the graphite composite gasket body is circular in shape.

[0019] The beneficial effect of adopting the above further solution is that the graphite composite gasket body can be better used by opening the through hole.

[0020] Furthermore, an outer sealing edge is embedded on the outer wall of the graphite composite gasket body, and an inner sealing edge is embedded on the inner side of the through hole.

[0021] The beneficial effect of adopting the above further solution is that by arranging outer and inner sealing edges on the outer and inner sides of the graphite composite gasket body, its structural strength can be effectively enhanced, making its structure more compact and preventing it from being easily damaged by extrusion.

[0022] Compared with the prior art, the present application provides a new type of graphite composite gasket, which has the following beneficial effects:

[0023] 1. The new graphite composite gasket is convenient for workers to calibrate the graphite composite gasket body with the mounting hole between two objects when installing it. The graphite composite gasket body can be installed without adjusting it, which greatly improves the installation efficiency of the graphite composite gasket body, thereby achieving the advantages of strong practicality and easy installation, and effectively solves the problem that the graphite composite gasket must be aligned with the mounting hole between two objects before it can be installed.

[0024] 2. The new graphite composite gasket has two layers of graphene, which makes the thermal conductivity of the graphite composite gasket body better. The heat of the graphite composite gasket body can be quickly dissipated by installing the first breathable layer and the second breathable layer. At the same time, the heat can be dissipated from the air holes opened on the surface of the first breathable layer and the second breathable layer. The flame retardant layer makes the graphite composite gasket body have a flame retardant effect by installing the flame retardant layer. The first wear-resistant layer and the second wear-resistant layer make the graphite composite gasket body more wear-resistant and not easy to be damaged. The anti-oxidation layer makes the graphite composite gasket body not easy to be oxidized. At the same time, the second wear-resistant layer further enhances the wear resistance of the graphite composite gasket body. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, the graphite composite gasket body 1 includes a heat-conducting braided layer 11, a graphene layer 12, a first air-permeable layer 13, a second air-permeable layer 14, a flame-retardant layer 15, an anti-oxidation layer 16, a first wear-resistant layer 17 and a second wear-resistant layer 18. The two layers of graphene layers 12 make the thermal conductivity of the graphite composite gasket body 1 better. The flame-retardant layer 15 makes the graphite composite gasket body 1 effectively flame-retardant in the event of an accident, thereby enhancing protection.

[0031] The heat-conducting braided layer 11 is in the middle, and there are two graphene layers 12, and the two graphene layers 12 are located on both sides of the heat-conducting braided layer 11. The first air-permeable layer 13 and the second air-permeable layer 14 are respectively connected to the side away from the two graphene layers 12. By installing the first air-permeable layer 13 and the second air-permeable layer 14, the heat of the graphite composite gasket body 1 can be quickly dissipated.

[0032] It should be noted that the first air permeable layer 13 and the second air permeable layer 14 have the same specifications, and air holes are provided on the surfaces of the first air permeable layer 13 and the second air permeable layer 14.

The second air permeable layer 14 is connected between the anti-oxidation layer 16 and another graphene layer 12, and the second wear-resistant layer 18 is connected to the outermost side of the anti-oxidation layer 16. The anti-oxidation layer 16 makes the graphite composite gasket body 1 less likely to be oxidized, while the first wear-resistant layer 17 and the second wear-resistant layer 18 make the graphite composite gasket body 1 more wear-resistant and less likely to be damaged, and the second wear-resistant layer 18 further enhances the wear resistance of the graphite composite gasket body 1.
