Oxygen generator separation valve
By adopting a non-circular mating surface and annular sealing ring groove design in the oxygen generator's separation valve, the problems of unstable sealing rings and leakage are solved, resulting in better sealing performance and convenient replacement of the valve plate, thus improving the stability and maintainability of the equipment.

AI Technical Summary
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.
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.
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.
