Specific embodiment
Following description is substantially merely exemplary and is not intended to limitation the utility model, application and purposes.It should
Understand, in all these attached drawings, similar appended drawing reference indicates identical or similar part and feature.Each attached drawing only shows
The design and principle for illustrating to meaning property the embodiments of the present invention, might not show each implementation of the utility model
The specific size and its ratio of mode may illustrate this by the way of exaggeration in the specific part in specific attached drawing or figure
The correlative detail or structure of each embodiment of utility model.
Fig. 1 is the solid for being equipped with the flowtube 10 of the coriolis mass flowmeters of supporting element according to prior art
Figure.As shown in Figure 1, when supporting element 21 is installed on flowtube 10, the buckled zone that needs that supporting element 21 is made to pass through flowtube 10
Domain 11.
Fig. 2 be according to prior art supporting element 21 pass through coriolis mass flowmeters flowtube 10 buckled zone
Along the sectional view for extending axis interception of flowtube 10 when domain 11.Fig. 3 is the perspective view of supporting element 21 according to prior art.
Fig. 4 is the front view of supporting element 21 shown in Fig. 3.As shown in Figure 3 and Figure 4, it is in oblong sheet shaped piece that supporting element 21 is overall.Supporting element
21 openings 22 with cylinder corresponding with flowtube 10, the opening 22 extend along the thickness direction of supporting element 21.
Refer again to Fig. 2, wherein OD is the outer diameter of flowtube 10, and R is the bending radius of flowtube 10, and T is supporting element 21
Thickness, H are the minimum diameter that may pass through the opening 22 of the supporting element 21 in bending region 11 of flowtube 10.It is readily apparent that
If you do not need to pass through bending region 11, the 22 diameter H of being open only needs the outer diameter OD of equal or slightly larger than flowtube 10.And work as
When supporting element 21 is needed across bending region 11, the 22 diameter H of being open needs outer diameter OD much larger than flowtube 10.Moreover, removing
Outside the outer diameter OD of flowtube 10, the 22 diameter H and thickness T of the radius of curvature R of flowtube 10 and supporting element 21 that is open is also same
Shi Xiangguan.As described above, the diameter H of opening 22 needs the outer diameter OD much larger than flowtube 10, brought problem is: supporting
When the bending region 11 that part 21 passes through flowtube 10 reaches straight tube region 12, the gap between opening 22 and flowtube 10 is excessive,
The welding being unfavorable between the two is for example brazed.And due to the excessive gap, the support chip 21 and flowtube of the prior art
10 are difficult to keep vertical.
Fig. 5 is the perspective view of another supporting element 31 according to prior art.Fig. 6 is facing for supporting element 31 shown in Fig. 5
Figure.Fig. 5 and supporting element shown in fig. 6 31 have the gap 33 in the side band of opening 32.This gap 33 is supportted greatly in a pre-installation, makes to prop up
Support member 31 passes through bending region 11.After part 31 to be supported reaches straight tube region 12, then using making gap 33 by the way of clamping
It reduces.Although this mode, which solves the problems, such as that the diameter H of opening 32 is excessive, is unfavorable for welding such as soldering, due to supportting greatly
Gap 33 makes supporting element 31 produce plastic deformation, so it is difficult to ensure that the consistency of production.

It is equipped with insertion piece 44.Each insertion piece 44 is made of two semi-circular shape parts.The Internal periphery of insertion piece 44 is rounded, thus with
The outer surface of flowtube 10 matches.The internal diameter of the Internal periphery of insertion piece 44 is slightly larger than the outer diameter of flowtube 10, consequently facilitating weldering
It connects, and is easy that support component 40 is made to keep vertical with flowtube 10.Additionally, it is envisioned that each insertion piece is not necessarily required to
It is to be made of two semi-circular shape parts, can also be made of any two complementary ring parts, as long as they are constituted together
One complete annulus.Obviously, to be easily installed, opening greater than the ring part of 180 degree in thus configured insertion piece
Mouth needs the outer diameter greater than flowtube.
During installation, so that flowtube 10 is passed through the opening 42 of supporting element 41, supporting element 41 is placed in, flowtube 10 is carried out
The predetermined position of support.Later, by two semi-circular shape parts of insertion piece 44 be respectively placed in supporting element 41 and flowtube 10 it
Between, form it into a complete annulus.Insertion piece 44 is connect with flowtube 10 for example, by welding, by each of insertion piece 44
Part connects, and insertion piece 44 is connect with supporting element 41, and support component 40 is made to keep vertical with flowtube 10.
The support component of the utility model can according to need the form using variation.
Figure 12 is the perspective view of the alternative embodiment of support component according to the present utility model.Figure 13 is according to this reality
With the perspective view of the supporting element in the alternative embodiment of novel support component.Figure 14 is support according to the present utility model
The perspective view of insertion piece in the alternative embodiment of component.As shown, supporting element 51 is total in alternative embodiment
Body is rectangle sheet shaped piece.The opening 52 of supporting element 51 is in rectangle.Correspondingly, the outer profile of insertion piece 54 is in rectangle, thus with
The opening 52 of supporting element 51 matches.The Internal periphery of insertion piece 54 is rounded, to match with the outer surface of flowtube 10.
Alternatively, according to actual needs, the outer profile of supporting element can have any shape.Alternatively, only
Want easy to process, convenient for welding, the opening of supporting element is not necessarily round, and can be any shape.Alternatively, insertion piece
