RTO lift valve sealing structure and heat accumulating type thermal oxidation furnace equipment

The utility model discloses an RTO lift valve sealing structure and heat storage type thermal oxidation furnace equipment, the lift valve sealing structure comprises a valve rod, a valve plate, a valve seat, a sealing seat, a sealing ring and sealing elastic pieces, the sealing seat with a sealing hole is installed on the valve seat, the sealing ring is arranged on the sealing seat, and the multiple sealing elastic pieces are arranged on the side, facing the valve seat, of the valve plate at intervals. After the valve plate moves towards one side of the valve seat, at least one sealing elastic piece is attached to the sealing hole to form a first seal, and the valve plate is attached to the sealing ring to form a second seal. And the first sealing and the second sealing are used at the same time, so that the sealing effect is better. And by adopting the double-sealing structure, when the first sealing structure fails, the second sealing structure can also play a role in preventing gas leakage, so that the pos
