Description
Technical field
The present invention relates to a kind of for combustion turbine exhaustion diffuser, for compensating and the expansion joint of thermal expansion between regulating gas turbine and exhaust section and vibration.
Background technique
Existing for combustion turbine exhaustion diffuser at present, its structure of expansion joint of compensation and the thermal expansion between regulating gas turbine and exhaust section and vibration is all made up of two sections of bellowss and middle adapter, 2 road circumferential welds are needed between bellows and middle adapter, this makes the reliability of this expansion joint good not, particularly vibration resistance, and the weight of product is also larger.
Summary of the invention
Object of the present invention is exactly for above-mentioned the deficiencies in the prior art, and provide a kind of reliability high, vibration resistance is good, product weight light for combustion engine system compound band precompressed mechanism expansion joint.
The technical solution used in the present invention is as follows:
A kind of for combustion engine system compound band precompressed mechanism expansion joint, it is characterized in that it includes bellows, one end and first of described bellows is taken over one end and is connected, and the bellows the other end is connected with one end of conical pipe; The inner side of described bellows is provided with inside lining sleeve, and inside lining sleeve one end is connected to described first nozzle inner wall, and the inside lining sleeve the other end is positioned at inside described conical pipe assembly, and rod assembly two ends are connected to the inwall of inside lining sleeve and conical pipe assembly respectively.
Described first adapter outer wall is provided with the first steel plate, and conical pipe assembly outer wall is provided with the second steel plate, is provided with safety cover outside bellows, and the two ends of safety cover are connected to described first steel plate and the second steel plate respectively.
Described conical pipe assembly outer wall is provided with hanger.
Described conical pipe assembly inwall is connected with the second adapter, and the second adapter is in described inside lining sleeve between the port that should hold and conical pipe assembly.
The outside of described first adapter, safety cover and conical pipe assembly is provided with thermal insulation layer, and corresponds to the second adapter position inside conical pipe assembly and be also provided with thermal insulation layer.
The connecting port place of described first adapter is provided with the first ring flat-plate, and the connecting port place of described conical pipe assembly is provided with the second ring flat-plate.
Described conical pipe assembly osculum end is connected with bellows 1, and its big opening end inwall is provided with supporting component.
Beneficial effect of the present invention has:
Product reliability is high, vibration resistance is good, quality of product is lighter, the pre-modified gear of expansion joint band and transport erecting device, facilitate in-site installation and regulate displacement, outer shield is detachable, is convenient to inservice inspection, product bore large (more than DN2000), the ring flat-plate that two ends, left and right are arranged also is convenient to field pipes abutting joint.Due to the structure adopting intermediate wavelet to instead of former middle adapter, the wall ratio middle adapter wall thickness of small echo is thin, so weight can lighten.And because that small echo middle instead of the structure of former middle adapter, compare middle adapter, decrease 2 road circumferential welds between bellows and middle adapter, and the moment of inertia of small echo is larger, so vibration resistance is better.
