Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a shock-absorbing sealing ring. Background Art

[0002] Flange joints have various structural forms. Most joints are "passive" seals under the premise of ensuring that the sealing structure meets the design, manufacturing and maintenance requirements. That is, the required compression rate of the sealing ring in the joint must be maintained under working conditions. Once the compression rate is reduced due to installation problems or loose installation, the sealing effect of the joint will be reduced. This phenomenon is more significant for airtightness, which is the most difficult to seal.

[0003] The Chinese patent document with publication number CN202521089U discloses a sealing ring, which has the dual performance of pressure sealing and active sealing. When the sealing connection is abnormal and the designed sealing conditions are not met, the normal pressure sealing fails, and compensation is made to produce a second seal, so that the sealing structure has a large "redundancy" and improves reliability. Even if other structural parts cannot perform the designed functions well, the sealing function of the original designed rectangular ring body can still be maintained;

[0004] However, the device does not have shock-resistant properties during use, which makes the device body susceptible to vibrations, causing the sealing ring on the device body to vibrate. The sealing ring becomes loose during the shaking process, resulting in a decrease in sealing performance, which needs to be improved. Utility Model Content
