Although it has good corrosion resistance, due to different usage environments, a single sealing ring cannot provide good corrosion resistance, which reduces its service life. At the same time, during the installation and use process, the sealing ring may be damaged or cracked due to improper operation by the staff, and has low strength and weak deformation resistance.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The outer wall of the sealing ring body is provided with an installation groove for installing and fixing the reinforcement ring. After the reinforcement ring is installed, the outer wall is flush with the outer wall of the sealing ring body for normal use. The reinforcement ring is made of glass fiber, which has high strength, strong tensile strength, high temperature tolerance, and aging resistance, thereby effectively protecting the sealing ring body and playing a beam-forming role, avoiding the sealing ring body from being broken by force, resisting deformation, and extending the service life. At the same time, the reinforcement ring made of glass fiber has good corrosion resistance and can withstand the erosion of various acids, alkalis and chemicals, so it can be used in various acidic and alkaline environments;

[0013] The first corrosion-resistant layer is fluororubber, which has excellent oil resistance, heat resistance and corrosion resistance, so that the sealing ring can be used in high temperature environments and can maintain sealing in corrosive media such as acids, alkalis, and oils.

[0014] The wear-resistant layer is made of polyurethane, which has good wear resistance and corrosion resistance. It has a good wear-resistant effect from the outside to avoid wear of the sealing ring and affect its service life. The inner side of the sealing ring body is fixedly connected with multiple annular edges distributed up and down to increase the friction between the sealing ring body and the external sealing groove, making the sealing ring body more firmly installed.
