By using above-mentioned technical proposal, when public ring flange and mother law orchid chuck clamping are on access panel, sealing ring by
It squeezes, internal diameter becomes smaller, so that the inner diameter abutment of sealing ring on heat exchanger tube, thus further improves through hole and changes
Leakproofness between heat pipe.
Further, the sealing ring is bonded with graphite linings relative to the two sides of male ring flange and female ring flange respectively.
By using above-mentioned technical proposal, when public ring flange and mother law orchid chuck clamping, graphite linings are squeezed, and are made with this
It obtains male ring flange and female ring flange closely fits in sealing ring.
In conclusion the utility model has the following beneficial effects: between weld-ring makes between female ring flange and heat exchanger tube
Gap is filled, and when male ring flange and female ring flange locking, weld-ring is filled in through hole, using between through hole and weld-ring
Conflict, with this reach sealing heat exchanger tube and through hole between gap the advantages of, improve and sealed between heat exchanger tube and through hole
Property.
