AI Technical Summary

Technical Problem

The existing oxygen generator separator valve has an unstable sealing ring, which is susceptible to external corrosion and leakage. Furthermore, the increased adhesion between the rotating plates may cause jamming.

Method used

The design employs a non-circular mating surface and annular sealing groove. The fixed valve plate is embedded in the groove and is prevented from rotating by the non-circular mating surface. Combined with the T-shaped sealing ring and the annular stepped surface, a multi-point line contact sealing structure is formed.

Benefits of technology

It improves sealing performance, avoids leakage and jamming problems, makes the sealing structure more stable, and facilitates the disassembly and adjustment of the valve plate.
