Problems solved by technology
[0003] During the long-term multiple sealing process, especially in the harsh testing environment, the sealing ring is prone to wear or premature aging damage. Therefore, the sealing ring needs to be replaced. The unreasonable structural design of the existing sealing components is likely to cause the sealing The ring replacement steps are cumbersome and the performance of the replaced sealing ring is not as good as before.

The invention discloses a downward-pressing type annular sealing assembly. The downward-pressing type annular sealing assembly comprises an upper sealing mounting plate, an upper sealing framework and an upper sealing ring, wherein a receding through groove penetrating through the upper surface and the lower surface of the upper sealing mounting plate is formed in the upper sealing mounting plate, so that the upper sealing mounting plate is of an annular structure, the upper sealing framework and the upper sealing ring are embedded in the lower surface of the upper sealing mounting plate and surround the edge of the receding through groove, the lower surface of the upper sealing mounting plate is provided with an upper sealing mounting groove which is arranged around the edge of the receding through groove, and the upper sealing framework is detachably installed in the upper sealing mounting groove. According to the downward-pressing type annular sealing assembly, the disassembly and assembly steps are simplified, and through the nested structural design, on one hand, stable supporting force can be provided for a lower sealing ring, and on the other hand, the replaced lower sealing ring can maintain the sealing property similar to that of the original sealing ring.
Description
technical field [0001] The invention relates to the field of non-standard automation, in particular to a push-down annular sealing assembly. Background technique [0002] In the leak detection in the field of non-standard automation, it is well known that sealing components with different structures are used to seal the workpiece to be tested. In the process of researching and realizing the sealing of the workpiece to be inspected, the researchers found that the sealing components in the prior art have at least the following problems: [0003] During the long-term multiple sealing process, especially in the harsh testing environment, the sealing ring is prone to wear or premature aging damage, so the sealing ring needs to be replaced. The unreasonable structural design of the existing sealing components is likely to cause the sealing The ring replacement steps are cumbersome and the performance of the replaced sealing ring is not as good as before. [0004] In view of this...
