Property wall contacts with the outer shroud wall of annular flake.Turning distribution plate drives annular flake to rotate, and the inner ring wall of annular flake is tight
Paste the ring wall surface of annular air dividing plate and the outer shroud wall of rotating distribution plates.
The present invention is further improved, the optimization technique measure taken is：Annular supporting plate top is fixed with annular oil
Groove, annular flake are arranged in annular oil groove with shell fragment support.
The present invention is further improved, the optimization technique measure taken is：Pacify on the upper ring wall surface of annular oil groove
Equipped with seal groove, seal is installed in the seal groove；Seal contacts sealing with the lower wall surface of rotating distribution plates.
Beneficial effect
Based on above technical scheme, the ring plate sealing device of Regenerative Combustion System rotating type change valve of the present invention, at least have
There is one of following beneficial effect：
1, rotary spool drives annular flake to rotate, and annular flake is close to annular under the elastic reaction of arc spring lamination and divides gas
The outside wall surface of plate is slided, and seals the leakage-gap between annular air dividing plate and rotating distribution plates；
2, annular flake is arranged in annular oil groove, and lubricating oil reduces annular flake and the friction of annular air dividing plate outside wall surface
Coefficient, while play sealing function；
3, seal groove is installed on the upper wall surface of annular oil groove, seal is installed in seal groove, adds sealing effectiveness,
The leakage of untreated exhaust gas is prevented to greatest extent.
