Concrete, after this structure installment is between adjacent vacuum tube, the guide shell arranged is as the fluid flow passageway of FlexbleJoint ripple compensation section, make flowing medium can partly or entirely by the ripple compensation section flowing through FlexbleJoint in this fluid flow passageway, this ripple compensation section is on FlexbleJoint for deformation-compensated bellows segment, like this, guide shell can effectively reduce or stop the wash away fluid flowing that rub and occur in ripple compensation section of fluid to ripple compensator section in FlexbleJoint and stir, and the structural type that one end of above guide shell is free end does not affect ripple compensation section pipeline axially deformation-compensated, make this structure under the prerequisite not affecting deformation-compensated effect, reach the object extending the FlexbleJoint life-span.
Further technological scheme is:
The for the benefit of uniformity that flows in flowline of fluid, is beneficial to and reduces the vibrations of pipeline and the stressed of even FlexbleJoint each point, the axis of described guide shell and the axis collinear of FlexbleJoint.
The structural type realizing Flange joint adjacent vacuum pipe is convenient to as a kind of, with being convenient to, FlexbleJoint and guide shell are arranged as a whole structural type, make the pipe fitting of FlexbleJoint and guide shell integrally structure, be beneficial to installation and the replacing of user, the linkage structure that described FlexbleJoint two ends are used for being connected with two ends vacuum tube is respectively compensator flange, any one end of described guide shell is fixed on the center bore inner wall face of any one compensator flange, and the other end of guide shell is between the two ends of another compensator flange.Above structure forms the connection of each pipe fitting or pipeline section in pipeline by the structural type all arranging interior pipe flange at the inner pipe end of adjacent vacuum pipe abutting end.
For making can to realize good sealing with the endoporus of FlexbleJoint outside guide shell, to reduce the effect of fluid to FlexbleJoint ripple compensation section, with the concentricity being beneficial to maintenance guide shell and FlexbleJoint, be beneficial to the stationarity of fluid in flow process, be beneficial to and reduce pipeline vibrations, the fixed end of described guide shell is provided with round speaker mouth, the external diameter of described round speaker mouth is equal with the center hole internal diameter of compensator flange, and the external diameter of guide shell remaining part is less than the bore inner diameter of FlexbleJoint.
Seal as one and be connected reliably, and being convenient to the Placement of realization, described round speaker mouth is welded to connect by circumferential weld with corresponding compensator flange.
The utility model has following beneficial effect:
In the utility model, after this structure installment is between adjacent vacuum tube, the guide shell arranged is as the fluid flow passageway of FlexbleJoint ripple compensation section, make flowing medium can partly or entirely by the ripple compensation section flowing through FlexbleJoint in this fluid flow passageway, this ripple compensation section is on FlexbleJoint for deformation-compensated bellows segment, like this, guide shell can effectively reduce or stop the wash away fluid flowing that rub and occur in ripple compensation section of fluid to ripple compensator section in FlexbleJoint and stir, and the structural type that one end of above guide shell is free end does not affect ripple compensation section pipeline axially deformation-compensated.
Therefore the structure that the utility model provides is under the prerequisite not affecting deformation-compensated effect, the object extending the FlexbleJoint life-span can be reached, be beneficial to the rate of fault and maintenance cost that reduce whole pipeline.
