The three-dimensional compensator comprises a corrugated pipe assembly I, a corrugated pipe assembly II, a lining pipe I, a lining pipe II, a connection pipe I, a connection pipe II, and a connection pipe III, wherein each corrugated pipe assembly comprises a corrugated pipe, the connection pipe II, an annular plate, a lug plate, a nut and a pull rod, two ends of the corrugated pipe are connected with the annular plate and the lug plate through the connection pipe II respectively, the annular plate is connected with the pull rod and the lug plate through the nut, one end of the corrugated pipe assembly I is connected with the connection pipe I, one end of the corrugated pipe assembly II is connected with the connection pipe III, the corrugated pipe assembly I is connected with the corrugated pipe assembly II through an intermediate connection pipe, the connection pipe I is connected with the lining pipe I which is connected with the intermediate connection pipe, and the intermediate connection pipe is connected with the lining pipe II which is connected with the connection pipe III. The three-dimensional compensator is special applicable to pulverized coal conveying pipelines, the deflection angle displacement amount and the axial displacement amount of the compensator are large, and large displacement produced when a pipeline device is operated can be effectively compensated and absorbed; the three-dimensional compensator is simple in structure, practical, long in service life, and convenient to manufacture, install, and maintain.
Description
Technical field
The present invention relates to pipeline compensator technical field, especially a kind of three-dimensional corrugated expansion joint that is exclusively used in power transportation pipe.
Background technique
At present, the industry such as electric power, building materials, heating power generally all need to be installed and used three-dimensional tube compensator in pipeline.Three-dimensional tube compensator has ball compensator and corrugated expansion joint conventionally, Three-D compensator can be made radial angle displacement and axial direct linear displacement, its deflection angle is large, axial displacement is large, can effective compensation and produce during the equipment operation such as absorption boiler compared with big displacement quantity.The three-dimensional corrugated expansion joint that install in existing power plant and cement plant is generally for cigarette wind or pulverized coal channel design, the structure relative complex of three-dimensional tube compensator, manufacture and install all inconvenient, three-dimensional corrugated expansion joint uses leakage phenomenon just easily occurs for three to five years, thereby must change compensator, cause the working life of compensator short, safeguard that replacing workload is large, cost is high.
Summary of the invention
Deficiency for above existing three-dimensional corrugated expansion joint, the object of this invention is to provide a kind of three-dimensional corrugated expansion joint that is exclusively used in power transportation pipe.
The object of the invention is by realizing by the following technical solutions:
Three-dimensional coal dust dedicated compensator, comprise adapter, bellows component and internal lining pipe, bellows component is connected with adapter, described internal lining pipe is set in bellows component, described bellows component comprises bellows, takes over II, ring flat-plate, otic placode, nut and pull bar, the two ends of described bellows are connected with otic placode with ring flat-plate respectively by taking over II, between ring flat-plate and otic placode, by nut, are connected with pull bar; Described compensator comprises two groups of bellows components, wherein, one end connecting tubes I of bellows component I, one end connecting tubes III of bellows component II, is connected by middle adapter between bellows component I and bellows component II.
As the preferred technical solution of the present invention, described adapter I is connected with the internal lining pipe I of bellows component I, described internal lining pipe I is connected with described middle adapter by otic placode, and middle adapter is connected with the internal lining pipe II of bellows component II, and internal lining pipe II is connected with adapter III by ring flat-plate.
