Abstract
A kind of type metal expansion joint of condensate water-proof corrosion, including being located at the adapter tube at type metal expansion joint both ends and the work bellows of the metal material positioned at middle part, it further include cydariform bellows and middle adapter, the medium outflow side of work bellows is arranged in cydariform bellows, the arrival end of cydariform bellows and the outlet end soldering of middle adapter, the adapter tube soldering of the outlet end and outlet end of cydariform bellows, the outlet end for the bellows that works and the arrival end soldering of middle adapter.The utility model adds a drum type bellows in work bellows side, cydariform bellows uses the stainless steel compared with thick wall to make, cydariform bellows has better resistance to corrosion and deeper interior trough compared to work bellows, cydariform bellows has retained condensate liquid, condensate liquid is avoided to enter work bellows, it is thus eliminated that work bellows is condensed the drawbacks of aqueous corrosion, the service life of type metal expansion joint is improved.
Description
Technical field
The utility model relates to a kind of components for pipe-line system, the especially type metal expansion joint of condensate water-proof corrosion.
Background technique
The enterprises such as steel mill, power plant, chemical industry pipe-line system generally uses type metal expansion joint, due to transmission medium temperature compared with
Height changes with pipeline internal and external temperature during media flow, will form condensate liquid in pipeline, condensate liquid is flow backwards in pipeline
Into in the core component work bellows of type metal expansion joint, and accumulate at the trough in work bellows.Contain in condensate liquid
Be corrosive substance, due to accumulate in the condensate liquid in metal bellows it is not volatile and discharge, the condensate liquid pair accumulated for a long time
Metal bellows generates corrosiveness, then makes metal bellows that corrosion and damage occur, affects the normal use longevity of bellows
Life.
Utility model content
The purpose of this utility model is that aiming at the disadvantages of the prior art, a kind of avoidable condensed water is provided and enters metal wave
The type metal expansion joint that line pipe, the condensate water-proof to improve service life corrode.
Problem described in the utility model is realized with following technical proposals:
A kind of type metal expansion joint of condensate water-proof corrosion, including being located at the adapter tube at type metal expansion joint both ends and positioned at middle part
The work bellows of metal material, further includes cydariform bellows and middle adapter, and work bellows is arranged in cydariform bellows
Medium outflow side, the arrival end of cydariform bellows and the outlet end soldering of middle adapter, the outlet end and outlet of cydariform bellows
The adapter tube soldering at end, the outlet end for the bellows that works and the arrival end soldering of middle adapter.
The type metal expansion joint of above-mentioned condensate water-proof corrosion, the cydariform bellows is stainless steel material, and cydariform bellows is
Unicast section, the wave that the wave of cydariform bellows is wider than work bellows is wide, and the wave height of cydariform bellows is greater than work bellows
Wave height, the wall thickness of cydariform bellows are greater than the wall thickness of work bellows.
The type metal expansion joint of above-mentioned condensate water-proof corrosion, the cydariform bellows are arranged right below drain valve.
The type metal expansion joint of above-mentioned condensate water-proof corrosion further includes guide shell, and guide shell setting is in work bellows and drum
In shape bellows.
The utility model accumulates aiming at the problem that condensed water is easily corroded metal bellows to be improved, in metal material
Work bellows side add a drum type bellows, cydariform bellows is not using more preferably compared with thick wall, corrosion resistance
The steel that becomes rusty makes, and cydariform bellows has deeper interior trough compared to work bellows, and cydariform bellows has retained condensate liquid, avoided
Condensate liquid enters work bellows, it is thus eliminated that work bellows is condensed the drawbacks of aqueous corrosion, improves type metal expansion joint
Service life.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Each list of reference numerals in figure are as follows: 1, adapter tube, 2, cydariform bellows, 3, middle adapter, 4, work bellows, 5, water conservancy diversion
Cylinder, 6, transport pull rod, 7, drain valve.
Specific embodiment
Referring to Fig. 1, type metal expansion joint described in the utility model includes adapter tube 1, the metal material positioned at middle part positioned at both ends
The work bellows 4 of matter further includes cydariform bellows 2 and middle adapter 3.The medium of work bellows is arranged in cydariform bellows
Outflow side, the arrival end of cydariform bellows and the outlet end soldering of middle adapter, the outlet end of cydariform bellows and outlet end
Adapter tube soldering, the outlet end for the bellows that works and the arrival end soldering of middle adapter.In work bellows and cydariform bellows
Equipped with guide shell 5, right end (close to the input end of work bellows) and the adapter tube soldering of guide shell.In middle adapter and far from drum
Setting transport pull rod 6 between the adapter tube of shape bellows.The stainless steel material production that pipe cydariform bellows selects corrosion resistance strong, drum
Shape bellows is unicast section, and the wave that the wave of cydariform bellows is wider than work bellows is wide, and the wave height of cydariform bellows is greater than work
Make the wave height of bellows, the wall thickness of cydariform bellows is greater than the wall thickness of work bellows.Cydariform bellows in the present embodiment
Wall thickness is 6 millimeters.It is arranged right below drain valve 7 in cydariform bellows, can be convenient and timely exclude to accumulate in cydariform bellows
Interior condensed water.After cydariform bellows is arranged, the condensate liquid flow backwards in pipeline is flowed into cydariform bellows, and condensate liquid is avoided to enter
Work bellows, it is thus eliminated that the drawbacks of condensed water anticorrosion work bellows.
