Description
Technical field
The utility model relates to the target bar of target type meter, particularly target type meter is spacing and protection mechanism.
Background technology
Target type meter measuring principle is the numerical value corresponding relation that the power that the flow of fluid and target piece are subject to has determination.Typically
Power conversion has three kinds of patterns：The sensor type and strain-type of force balance type, micro-displacement.
The power switching mechanism for the target type meter that the utility model is related to is exactly strain-type.
As shown in Figure 1, target type meter is by including target piece 1, target bar 3, strain-gage pickup 6, signal transacting shows table
First 8.
Target bar 3 is slender rod piece, for a long time by fluid force, is easily bent or even fractures, and causes flow measurement not
It is accurate or can not measure, to avoid target bar 3 from bending as far as possible, the limit component of target bar 3 is designed with actual applications.
The position-limit mechanism of prior art target bar 3 is made up of 4 connecting rod 3a, limiting plate 3b, connecting rod 3a upper ends and method
Orchid 4 is coordinated by screw thread to be fixedly connected, and connecting rod 3a lower ends coordinate with limiting plate 3b screw threads to be fixedly connected, limiting plate 3b central parts
On be provided with spacing hole, target bar 3, which is through in limiting plate 3b spacing hole, limits the oscillating quantity of target bar 3.
Above-mentioned prior art, connecting rod 3a is connected with the screw thread of flange 4, not only needs the auger shell pit on flange 4, increases
Sequence is processed, it is necessary to which first connecting rod 3a is screwed on flange 4 during assembling, the insertion limiting plate 3b of target bar 3 centers spacing hole
In, reassemble fixed limiting plate 3b, assembling process wastes time and energy, complex.Meanwhile, connecting rod 3a sheets are as elongated class bar
Part, by fluid force when long, be also easily bent or even fracture.
The position-limit mechanism of above-mentioned prior art target bar 3 can only limit the swing position of target bar 3, it is impossible to avoid fluid to target bar
3 impact forces, therefore flow is larger or during higher flow velocity, the position-limit mechanism of the target bar 3 can not be played to protection target bar 3
Effect.
Utility model content
The purpose of this utility model is to be improved for above-mentioned prior art deficiency there is provided one kind is rational in infrastructure, is protected
Effect is good, target type meter Ba Gan limit protections mechanism easy for installation.
The utility model target type meter Ba Gan limit protections mechanism, includes by target piece 1, target piece connecting rod 2, target bar 3, limit
Position pipe 5；
The upper end of position-limiting tube 5 is provided with internal thread 51, and the upper end of position-limiting tube 5 passes through under internal thread 51 and strain gauge transducer 6
The outer stud 61 at end, which coordinates, to be fixedly connected；
Target piece connecting rod 2 is fixedly connected on the central part of target piece 1, right on the front side wall and rear wall of the lower end of position-limiting tube 5
Horizontal direction should be offered（I.e. measurement pipe 7 is axial）Through hole 52a, 52b, target piece connecting rod 2 is slidably matched through the lower end of position-limiting tube 5
Through hole 52a, 52b on, on the end of the rear wall external target piece connecting rod 2 of position-limiting tube 5 be provided with spacing ring 21, to prevent target piece connecting rod
2 move forward extraction, and the lower end of target bar 3 is fixedly connected with target piece connecting rod 2 in position-limiting tube 5.
The utility model is simple and reasonable for structure.Position-limiting tube 5 coordinates fixed connect with the outer stud 61 that the lower end of sensor 6 is carried
Connect, position-limiting tube 5 is fixedly mounted with sensor 6 by the platen 62 on sensor 6 and pipe flange, and target piece 1 is placed in survey
In buret 7, install simple and convenient.
The rigidity of the utility model position-limiting tube 5 and stability are strong, can bear larger flow and indeformable.Target bar 3 is spacing
It can avoid the active force by fluid in pipe 5, the unrestricted position of target bar 3 mouthful effect, therefore flow is larger, flow velocity is very fast or long
During time effect situation, target bar 3 will not also bend and breakage phenomenon, it is ensured that and protective action spacing to target bar 3.
