| titleOfInvention | Metal seal structure for non-contact end face seal |
| abstract | The invention discloses a metal sealing structure for a non-contact end face seal, which comprises a rotating shaft, a sealing shell, a moving ring, a static ring, a static ring seat and a metal seal. The parts include the inner seal arm ring and the outer seal arm ring; a V-shaped opening groove is formed between the inner seal arm ring and the outer seal arm ring, and the inner surface of the inner seal arm ring is a raised arc surface, which is recorded as the inner seal Lip, the inner sealing lip cooperates with the static ring seat, the outer surface of the outer sealing arm ring is a raised arc surface, which is recorded as the outer sealing lip, and the outer sealing lip cooperates with the sealing housing; the inner sealing arm ring and the outer sealing arm The rings meet and extend out of the support arm ring, the end face of the support arm ring serves as a positioning surface, and the positioning surface is in close contact with the annular groove. The V-shaped opening groove in the present invention enables close contact between the inner sealing lip and the static ring seat, and between the outer sealing lip and the sealing shell to maintain sealing performance and strong resilience, and has a strong impact on the static ring and the moving ring. The ring has little effect on the performance of disengagement during operation. |
