The utility model discloses the data that record are accurate, and the accuracy is high.
Description
Technical field
The utility model relates to angularity survey instrument technical field, is specifically related to a kind of spherical tank angularity Special tool for checking.
Background technology
Angularity survey instrument of the prior art is confined to check Dg nominal diameter to be less than or equal to pressure vessel and the boiler of 3000mm.Range of application is narrow, function singleness.Further, in embody rule process, make template inspection accuracy by hand low, can not guarantee that data are authentic and valid.
Utility model content
In order to solve the deficiency that prior art exists, the utility model provides a kind of of many uses, easy to operate, spherical tank angularity Special tool for checking that accuracy rate is high.
Its technical scheme is:
A kind of spherical tank angularity Special tool for checking, comprises middle chi 1, vernier slice 2, middle chi clamp nut 3, main scale clamp nut 4, main scale 5, chi frame 6, measuring jaw 7, outer survey end 8, chord length reference graduation 9, action reference graduation 10, interior survey end 11, calibrated scale 12; Measuring jaw 7 is fixedly connected on chi frame 6, on chi frame 6, main scale 5 is embedded in the middle of chi frame 6 and measuring jaw 7, locked by main scale clamp nut 4, vernier slice 2 is fixedly connected on main scale 5, middle chi 1 is embedded in the middle of main scale 5 and vernier slice 2 locked by middle chi clamp nut 3, and outer survey end 8 and interior survey end 11 distribute the two ends of measuring jaw 7, indicate chord length reference graduation 9 at main scale 5, indicate action reference graduation 10 at vernier slice 2, be marked with calibrated scale 12 at middle chi 1.
The beneficial effects of the utility model:
The utility model compared with prior art, has the following advantages:
1, the data recorded are accurate, and degree of accuracy is high.
2, field practice proves, measuring method is proper, and for defects assessment, personnel provide precise information, guarantees spherical tank safe operation.
3, for inspection industry creates economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of spherical tank angularity Special tool for checking;
Fig. 2 is the schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in more detail.
As Figure 1-Figure 2, a kind of spherical tank angularity Special tool for checking, comprises middle chi 1, vernier slice 2, middle chi clamp nut 3, main scale clamp nut 4, main scale 5, chi frame 6, measuring jaw 7, outer survey end 8, chord length reference graduation 9, action reference graduation 10, interior survey end 11, calibrated scale 12; Measuring jaw 7 is fixedly connected on chi frame 6, on chi frame 6, main scale 5 is embedded in the middle of chi frame 6 and measuring jaw 7, locked by main scale clamp nut 4, vernier slice 2 is fixedly connected on main scale 5, middle chi 1 is embedded in the middle of main scale 5 and vernier slice 2 locked by middle chi clamp nut 3, and outer survey end 8 and interior survey end 11 distribute the two ends of measuring jaw 7, indicate chord length reference graduation 9 at main scale 5, indicate action reference graduation 10 at vernier slice 2, be marked with calibrated scale 12 at middle chi 1.
The principle of work and power of the present utility model and parameter declaration:
Physical dimension: 1200 × 120 × 10 scope of applications: 50m
3≤ V≤5000m
3v is spherical tank volume E be angularity Dg be nominal diameter L is chord length;
Principle: angularity refers to the maximal clearance E between the actual circular arc of a certain regulation chord length being symmetrical in detected weld and standard circular arc.This angularity detection ruler is with two measuring jaws tips and be in chi tip 3 representation theory circular arcs in reference position, and the readout that in using, chi slippage reflects measures gap and the angularity of actual circular arc and theoretical circular arc.
Using method: by nominal diameter and the respective standard requirement of tested spherical tank, measuring jaw spacing is adjusted to the corresponding graduation position that main scale marks.According to field condition, in container or outside container, detection ruler is affixed across detected weld and chamber wall, in slippage, chi makes it to be affixed with detected weld one lateral edges housing, read the difference E1 of the corresponding nominal diameter action reference graduation line shown in chi zero graduation to left or right vernier slice now, in like manner, translation dipping records the difference E2 that middle chi is positioned at weld seam opposite side, then in E1 and E2, absolute value the greater is detected weld angularity E.
Embodiment
As shown in Figure 2, certain 1000m
3spherical tank, middle chi in weld seam both sides 1., 2. position record E1=1.5mm respectively, E2=-2.0mm,
Then E=E2=-2mm gets | E1| and | the greater in E2|,
Symbol "+", "-" of angularity represent weld seam evagination and indent respectively.
The above; be only the utility model preferably embodiment; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.
