According to the wall-penetrating component, the expansion between the inner casing and the outer casing can be absorbed, the deformation caused by fixing connection is avoided, the stability of the boiler is improved, and the wall-penetrating component is convenient to mount, dismount and maintain.
Description
Technical field
The utility model relates to a kind of Turbo-charged Marine Boiler accessory, particularly relates to a kind of Turbo-charged Marine Boiler member through walls, belongs to the energy source and power industry.
Background technology
Supercharged steam generator refers to after air compressing that the gas-powered compressor of boiler smoke will enter compressor is pressurized to operating pressure and feeds boiler furnace, the burning of boiler is carried out under high positive pressure, burning is strengthened, furnace volume heat release rate increases substantially, greatly strengthened the heat transfer of burner hearth and convection heating surface, reduced steam steel quantity consumption per ton, thereby boiler volume and weight are reduced greatly, it is many that floor space is also little.Existing supercharged steam generator is generally double Shell, during production, various pipelines will be inserted into its inside through double Shell, generally adopt and be welded to connect while passing and between inside and outside shell, produce stress because the coefficient of expansion between ectonexine is different, long-time use can cause the damage of pipeline and shell structure to cause the accident, and maintenance difficult, this structure still needs to be improved.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of Turbo-charged Marine Boiler member through walls.
The technical solution adopted in the utility model is: a kind of Turbo-charged Marine Boiler member through walls, it is characterized in that being respectively equipped with circular hole on the inner casing of supercharged steam generator and shell, be provided with bellows between circular hole, outside diameter of bel is greater than the inner casing Circularhole diameter and is less than the shell Circularhole diameter; Bellows one end is connected with the interior brace of annular of interior receipts, interior brace is fixed by bolts on inner casing circular hole edge by terminal pad in annular, the bellows other end is connected with the outer brace of annular of abduction, and outer brace is fixed by bolts on shell circular hole edge by the outer terminal pad of annular; Be fixed with a pair of concentric ring flange on interior terminal pad, two ring flanges are connected with respectively sleeve pipe, are provided with pipeline in sleeve pipe, are provided with the packing be sealed on pipeline outer wall between ring flange; The pipeline outer end is welded with bolt and is connected to the ring flange on outer terminal pad.
Described inner casing circular hole and shell circular are respectively equipped with interior position limiting convex ring and outer position limiting convex ring.
In described annular, terminal pad is provided with the flange coincide in the inner casing circular hole.
Described bellows is steel material.
Described outer terminal pad is provided with the Pressure gauge be communicated with the bellows interior space
The utility model pipeline only is fixedly connected with shell, when between inner casing and shell, dilatancy being arranged, pipeline relatively with inner casing at packing_seal place telescopic movable, bellows is servo-actuated, the absorption swell increment avoids being fixedly connected with the deformation caused, improve Boiler Stability, the utility model, except the sealing of packing place, also utilizes telescopic bellows to form the second seal cavity outside packing simultaneously, can effectively improve sealing effectiveness and security, installation, convenient disassembly, be convenient to safeguard.
