The utility model ensures the resilience of the gasket by arranging the spring between the first metal layer and the second metal layer, and the graphite layer is arranged between the metal layer and the stainless steel layer, so that the gasket can be stably used for a long time under harsh working conditions, is rarely required to be maintained, and can prolong the service life and improve the use effect of the gasket; the utility model has the advantages of simple structure, stable performance and longer service life.
Description
Technical Field
The utility model relates to a gasket technical field especially relates to a compound graphite gasket.
Background
The gasket is a material used for strengthening the seal between two planes, and is used for preventing the two objects from leaking due to pressure, corrosion and natural expansion and contraction of the pipeline caused by the mechanical seal between the two objects. The graphite gasket is formed by cutting or punching a pure graphite plate or a metal reinforced graphite plate, has a plurality of excellent sealing performances, can be stably used for a long time under harsh working conditions, and needs little maintenance. In the prior art, the graphite gasket is composed of an inner metal ring and an outer metal ring and a graphite ring nested in the middle and is sealed through the graphite ring, but the inner metal ring and the outer metal ring of the gasket are easy to wear and deform after being contacted with a connecting piece for a long time, and have large deformation in an environment with large temperature change, so that the gasket is difficult to be applied to occasions with high sealing requirements for a long time. The particles generated by metal abrasion are not suitable for the fields with higher requirement on cleanliness, such as the fields of food, medicine, component production and the like.
Therefore, a graphite composite gasket capable of buffering impact and friction between the graphite gasket and a connecting piece and reducing pollution caused by gasket abrasion is urgently needed.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a composite graphite gasket for solving the above problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides a compound graphite gasket, includes the gasket body, the inside and outside both sides of gasket body are provided with the rubber circle, the inside of gasket body is provided with the spring to be located the outer both sides of spring are provided with the first graphite device and the second graphite device of sinusoidal wave structure.
The utility model discloses preferred, first graphite device includes first metal level, first graphite layer and first stainless steel layer, the both sides on first graphite layer are connected respectively first metal level with first stainless steel layer.
The utility model discloses preferred, second graphite device includes second metal level, second graphite layer and second stainless steel layer, the both sides on second graphite layer are connected respectively the second metal level with second stainless steel layer.
The utility model discloses it is preferred, the rubber circle respectively with first metal level the second metal level first stainless steel layer with the second stainless steel layer passes through the connecting piece and connects.
The utility model discloses it is preferred, first metal level with be provided with a plurality of springs between the second metal level.
The beneficial effects of the utility model reside in that:
the utility model ensures the resilience of the gasket by arranging the spring between the first metal layer and the second metal layer, and the graphite layer is arranged between the metal layer and the stainless steel layer, so that the gasket can be stably used for a long time under harsh working conditions, is rarely required to be maintained, and can prolong the service life and improve the use effect of the gasket; the utility model has the advantages of simple structure, stable performance and longer service life.
Drawings
Fig. 1 is a schematic structural view of a composite graphite gasket according to the present invention;
fig. 2 is a sectional view a-a of fig. 1.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 and 2: a composite graphite gasket comprises a gasket body 2, rubber rings 1 are arranged on the inner side and the outer side of the gasket body 2, a spring 8 is arranged in the gasket body 2, and lie in the outer both sides of spring 8 and be provided with sinusoidal structure's first graphite device and second graphite device, first graphite device includes first metal level 3, first graphite layer 4 and first stainless steel layer 2, first metal level 3 and first stainless steel layer 2 are connected respectively to the both sides on first graphite layer 4, second graphite device includes second metal level 6, second graphite layer 7 and second stainless steel layer 5, second metal level 6 and second stainless steel layer 5 are connected respectively to the both sides on second graphite layer 7, rubber circle 1 respectively with first metal level 3, second metal level 6, first stainless steel layer 2 and second stainless steel layer 5 pass through connecting piece 9 and connect, be provided with a plurality of springs 8 between first metal level 3 and the second metal level 6.
In summary, the utility model ensures the resilience of the gasket by arranging the spring between the first metal layer and the second metal layer, and the graphite layer is arranged between the metal layer and the stainless steel layer, so that the gasket can be stably used for a long time under harsh working conditions, the maintenance is rarely needed, and the service life and the use effect of the gasket can be improved; the utility model has the advantages of simple structure, stable performance and longer service life.
The present invention can be implemented by various modifications without departing from the spirit and spirit of the present invention, and the above description is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, and all the equivalent structural changes made by using the contents of the present invention and the accompanying drawings are included in the scope of the present invention.
