The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions.according to the high temperature universal type compensator that the utility model proposes, comprise end pipe one, end pipe two, two identical bellowss and two groups of pull bar groups of intervalve and connecting end pipe and intervalve, the two ends of bellows are welded on the pull bar group, one end of two groups of pull bar groups manages one with end respectively, two welding of end pipe, the other end of two groups of pull bar groups is welded to connect with intervalve two ends respectively, end Guan Yiyu intervalve, be the bell and spigot frame of large pipe box tubule between intervalve and end pipe two, in one end insertion end pipe one of intervalve, end pipe two inserts in the intervalve the other end, leave the free gap of certain the sphere of activities between bassoon and tubule.This applicable novel being arranged in the middle of high-temperature pipe, in when, under the effect of high-temperature pipe in power, radial and axial distortion occuring when, high temperature universal type compensator intervalve deflects, distance between end Guan Yiyu end pipe two is dwindled or enlarges, simultaneously the bellows on compensator is compressed or stretch, and the distortion of high-temperature pipe all directions is compensated.
Be the bell and spigot frame of large pipe box tubule between end Guan Yiyu intervalve, intervalve and end pipe two, in one end insertion end pipe one of intervalve, end pipe two inserts in the intervalve the other end, leave the free gap between bassoon and tubule, this gap length is according to amount of deformation size calculative determination, when radial deformation b occurs in end pipe, be enough to power is delivered to by this bell and spigot frame and make a ° of deflection of intervalve generation angle on intervalve, the high-temperature pipe radial deformation is absorbed.When high-temperature pipe generation axial deformation, distance between end Guan Yiyu end pipe two becomes L2 by initial length L1, the high-temperature pipe axial deformation is absorbed, be connected by the pull bar bond pads between end Guan Yiyu intervalve, intervalve and end pipe two, be installed by welding with bellows in the pull bar group, when axial and radial deformation occured high-temperature pipe, inhomogeneous stretching or compression had occured in bellows.
End Guan Yiyu intervalve, intervalve and end pipe two amongs arrange one group of pull bar group, and the pull bar group along the circumferential direction arranges, can by the adjustment of pull bar group with limit every group of amount of deformation that the bellows circumference is different, realize that high temperature universal type compensator amount of deformation is controlled.
The purpose of this utility model and solve its technical problem and can also adopt following technical measures further to realize.High temperature universal type compensator according to claim 1, it is characterized in that being the bell and spigot frame of large pipe box tubule between wherein said end Guan Yiyu intervalve, intervalve and end pipe two, or the nested structure that adopts of conventional FlexbleJoint, this nested structure not only seals, and also must have enough intensity deformation force can be delivered on intervalve.
Advantage of the present utility model
The utility model can improve the high-temperature pipe life-span
Due to the effect of high temperature universal type compensator, can avoid the uncontrollable distortion of pipeline to cause that the pipe lining extruding is damaged, thereby avoid conduit enclosure and FlexbleJoint that inner lining damage causes to burn out, extend pipeline life.
Due to the effect of high temperature universal type compensator, can avoid the uncontrollable distortion of pipeline to cause bellows excessively to stretch or compression and damaging.
In sum, high temperature universal type compensator described in the utility model has above-mentioned many advantages and use value, no matter structurally or larger improvement all arranged on performance, and produced handy and practical effect, and existing compensator has the multinomial effect of enhancement, thus more practical.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer elaboration technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
