Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a partially enlarged view a of fig. 1.
The sealing gasket comprises a sealing gasket body 1, an annular inner bone ring 2, a fiber net 3, an annular outer bone ring 4, an inner hole 5, a closed annular groove 6 and an annular convex strip 7.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely preferred embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
As shown in fig. 1, the embodiment of the present invention includes a gasket body 1 made of rubber.
The sealing pad body 1 is provided with a plurality of inner holes 5 corresponding to the sealing medium orifices, is positioned in the hole edge of the inner holes 5, is internally provided with an annular inner bone ring 2, and an inner sealing area is reserved between the annular inner bone ring 2 and the hole edge of the inner holes 5.
An annular outer bone ring 4 is arranged on the outer edge of the sealing pad body 1, and an outer sealing area is reserved between the annular outer bone ring 4 and the outer edge of the sealing pad body 1; the thickness of the sealing gasket body 1 where the annular inner bone ring 2 and the annular outer bone ring 4 are located is thinner than that of other areas. The high-temperature-resistant resin coating on the outer surface of the sealing gasket body 1 can improve the high-temperature-resistant effect of the sealing gasket body 1.
