Abstract
The utility model relates to a three-dimensional compensator for coal dust. The three-dimensional compensator for the coal dust comprises two groups of corrugated pipe assemblies, lining pipes and connecting pipes. Each corrugated pipe assembly comprises a corrugated pipe, the connecting pipe II, an annular plate, a lug plate, a nut and a pull rod, two ends of the corrugated pipe are respectively connected with the annular plate and the lug plate through the connecting pipe II, and the annular plate is connected with the lug plate through the nut and the pull rod; one end of the corrugated pipe assembly I is connected with the connecting pipe I, one end of the corrugated pipe assembly II is connected with a connecting pipe III, and the corrugated pipe assembly I is connected with the corrugated pipe assembly II through a middle connecting pipe; the connecting pipe I is connected with the lining pipe I, the lining pipe I is connected with the middle connecting pipe, the middle connecting pipe is connected with the lining pipe II, and the lining pipe II is connected with the connecting pipe III. The three-dimensional compensator for the coal dust is used for coal dust conveying pipelines, deflection angle displacement of the compensator is large, axial displacement of the compensator is large, and large displacement produced in the process of operation of pipeline devices can be effectively compensated and absorbed. The three-dimensional compensator for the coal dust is simple in structure, convenient and practical, long in service life and convenient to manufacture, install and maintain.
Description
Technical field
The utility model relates to the 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, industries such as electric power, building materials, heating power generally all need be installed and used the three-dimensional tube compensator in pipeline.The three-dimensional tube compensator has ball compensator and corrugated expansion joint usually, three-dimensional compensator can be done radial angle displacement and axially straight-line displacement, its deflection angle is big, axial displacement is big, produce in the time of effectively compensating and absorb the operation of equipment such as boiler than big displacement quantity.The three-dimensional corrugated expansion joint that install in existing power plant and cement plant is generally at cigarette wind or pulverized coal channel design, the structure relative complex of three-dimensional tube compensator, make and install all inconvenient, three-dimensional corrugated expansion joint uses leakage phenomenon just easily took place in three to five years, thereby must change compensator, cause the working life of compensator short, safeguard that the replacing workload is big, the cost height.
The model utility content
At the deficiency of above existing three-dimensional corrugated expansion joint, the purpose of this utility model provides a kind of three-dimensional corrugated expansion joint that is exclusively used in power transportation pipe.
The purpose of this utility model is achieved by the following technical solution:
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 the 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, are connected with pull bar by nut between ring flat-plate and the otic placode; Described compensator comprises two groups of bellows components, and wherein, an end of bellows component I connect to be taken over I, and an end of bellows component II connects takes over III, is connected by middle adapter between bellows component I and the bellows component II.
As optimal technical scheme of the present utility model, 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 the internal lining pipe II is connected with the adapter III by ring flat-plate.
As optimal technical scheme of the present utility model, be filled with filler between described adapter I and internal lining pipe I and bellows and the adapter II.
