Detailed ways

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby defining the protection scope of the present utility model more clearly. .

Please refer to Figures 1 to 5. A high-pressure combined sealing ring includes a sealing ring body 1 and an inner ring 2. The sealing ring body 1 is provided with an installation groove 3 on the inner wall. A wear-resistant layer 4 is provided on the outside of the sealing ring body 1. The side wall of the grinding layer 4 is adhered to the heat insulation layer 5, the side wall of the heat insulation layer 5 is adhered to the reinforcing layer 6, the side wall of the reinforcing layer 6 is adhered to the anti-corrosion layer 7, and the side wall of the anti-corrosion layer 7 is adhered to the anti-slip layer 8. The wear-resistant layer 4 is used to protect the sealing ring body 1 so as to avoid excessive wear during use, thereby protecting the sealing ring body 1 and extending its service life;

Two support plates 602 are installed inside the reinforcement layer 6, so that the movable rod 603 pushes the support plate 602 to move under the action of the spring 605, thereby pushing the sealing ring body 1 to fit the workpiece, which can ensure the sealing performance of the sealing ring body 1. A positioning rod 606 is installed between the two support plates 602. Several positioning sleeves 604 are installed in the middle of the positioning rod 606.
