The utility model relates to the technical field of sealing components, and more specifically, to a high-performance sealing component.

Background Art

When the pneumatic transmission system is in use, since the air rod needs to move, there is a certain gap between the cylinder body and the air rod. High-performance pneumatic seals are needed to seal the gap to prevent the medium from flowing out. Commonly used high-performance pneumatic seals are mainly round sealing rings and square sealing rings, etc. They have the advantages of simple structure, easy manufacturing and low cost. Therefore, they are dynamic sealing elements and static sealing elements widely used in pneumatic transmission systems.

Among them, it was found through searching that the utility model patent high-performance pneumatic seal with patent application number CN202223563473.1 includes a cylinder body, one end of which is fixed with a side cover, a piston in the cylinder body moves with a gas rod, the side cover is internally threadedly connected with a mounting shell, and the inner wall of the mounting shell is fixed with a first sealing ring and a second sealing ring;

When the structure is in use, the mounting shell can be initially fixed by threading the mounting shell with the side cover, and the mounting shell can be limited again in conjunction with the setting of the limiting mechanism, so that the first sealing ring and the second sealing ring can be fixed. The double fixation can prevent the first sealing ring and the second sealing ring from being displaced and sliding during use, and the mounting shell, the first sealing ring and the second sealing ring can be disassembled through the limiting mechanism for easy replacement. The corrosion resistance and wear resistance of the first sealing ring and the second sealing ring are enhanced through the anti-corrosion layer and the wear-resistant layer, reducing the probability of damage to the first sealing ring and the second sealing ring after long-term friction. However, the structure is not easy to be quickly installed together when in use, and is not convenient enough during installation.
