FIG. 1 is a top sectional view of the structure of the present invention;

FIG. 2 is a front sectional view of the structure of the present invention;

fig. 3 is a top cross-sectional view of the ring structure of the present invention.

In the figure: the rubber ring comprises a ring body 1, a support groove 2, an elastic metal support net 3, a lower isolation ring 4, an upper isolation ring 5, a polytetrafluoroethylene ring layer 6, a silica gel base layer 7, a fluororubber ring layer 8 and a nitrile butadiene rubber base layer 9.

Detailed Description

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 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.

Referring to fig. 1-3, a high oil-resistant rubber seal ring comprises a ring body 1, a supporting groove 2 is annularly arranged at the center of an inner ring of the ring body 1, an elastic metal supporting net 3 is embedded in an inner cavity of the supporting groove 2, the surface of an outer ring of the elastic metal supporting net 3 is tightly matched with the inner cavity of the supporting groove 2, the top and the bottom of the inner cavity of the ring body 1 are respectively and fixedly connected with a lower isolating ring 4 and an upper isolating ring 5, the lower isolating ring 4 and the upper isolating ring 5 are made of fluororubber, the ring body 1 comprises a silica gel base layer 7, a polytetrafluoroethylene ring layer 6 is fixedly connected with the surface of the outer ring of the silica gel base layer 7, a nitrile rubber base layer 9 is fixedly connected with the surface of the inner ring of the silica gel base layer 7, a fluororubber ring layer 8 is fixedly connected with the inner ring of the nitrile rubber base layer 9, and the supporting groove 2, the elastic metal supporting net 3, the lower isolating ring 4, the upper isolating ring 5, the polytetrafluoroethylene ring layer 6 and the fluororubber ring layer 8 are arranged in a matched way, the compression strength, the sealing performance, the high temperature resistance and the corrosion resistance of the sealing ring are improved, the service life of the rubber sealing ring is longer and more oil-resistant, the problems that the rubber sealing ring is damaged in the use process due to the fact that the self strength is lower, the sealing performance is poor, the high temperature and the corrosion resistance are poor, the rubber sealing ring is extremely easy to damage in the use process, the service life of the rubber sealing ring is short, and oil resistance is low are solved, and the rubber sealing ring is worthy of popularization.

When the rubber sealing ring is used, the supporting groove 2, the elastic metal supporting net 3, the lower isolation ring 4, the upper isolation ring 5, the polytetrafluoroethylene ring layer 6 and the fluororubber ring layer 8 are matched for use, so that the compression strength, the sealing property, the high temperature resistance and the corrosion resistance of the sealing ring are improved, the service life of the rubber sealing ring is longer and the rubber sealing ring is more oil-resistant, and the problems that the rubber sealing ring is shorter in service life and is not oil-resistant due to the fact that the self strength of the rubber sealing ring is lower, the sealing property is poorer, the high temperature and the corrosion resistance are poorer, and the rubber sealing ring is damaged in the using process are easily solved; the polytetrafluoroethylene ring layer 6 has high temperature resistance and corrosion resistance, so that the polytetrafluoroethylene ring layer can not react with concentrated acid, alkali or strong oxidant at high temperature; the working temperature of the fluororubber ring layer 8 is minus 40 ℃ and plus 300 ℃, so that the fluororubber ring layer can resist fuel oil, high temperature, Freon, superheated water and steam and has excellent chemical corrosion resistance.

In summary, the following steps: this high resistant oily rubber seal, through setting up support groove 2, elastic metal supporting network 3, lower cage spacer 4, go up cage spacer 5, polytetrafluoroethylene circle layer 6 and fluororubber circle layer 8's cooperation is used, rubber seal has been solved in the use, because of self intensity is lower, and the leakproofness is relatively poor, high temperature and corrosion resistance are relatively poor simultaneously, very easily make rubber seal damage in the use, thereby lead to rubber seal to appear the problem that life is short and not resistant oil.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
