Description

The measurement method of minor diameter tankage abutted flange concentricity
Technical field
The invention belongs to machinery industry vessel fabrication manufacture fields.
Background technology
In machinery industry, in tankage manufacturing process, it is often necessary to be symmetrically installed some pipe connecting flanges, exist sometimes The control of the precision of butt tube flange coaxiality, verticality and concentricity proposes relatively high particular/special requirement.About minor diameter The measurement of tankage abutted flange concentricity, the prior art measure the positioning of single pipe connecting flange only with 2 points of drawing chalk lines Size, overhanging height, span centre equidimension, this method measurement cumulative errors are big, concentricity difficulty or ease control, low production efficiency.
Invention content
The object of the invention:The defect for overcoming prior art measurement error big.
Minor diameter tankage abutted flange concentricity survey tool has:It is 1 handle of tape measure or Steel Ruler, 1, platform, contour Cushion block 2,1, square, chalk line or 2, steel wire;
Minor diameter tankage abutted flange concentricity measurement method:
1. vertical stand up of the cylinder 1 that group is installed to burner pipe connecting flange 6 is placed on platform 3, right on the basis of platform 3 first Each 6 height h1 of pipe connecting flange is measured, and checks whether 6 height of each burner pipe connecting flange is consistent, then with each pipe connection method On the basis of 4, the upper and lower, left and right checkpoint 7 of blue 6 trepannings, measure checkpoint 7 to 6 outer circle of pipe connecting flange distance h2 whether phase Deng, and whether the distance h3 for checking left and right checkpoint 7 to 6 sealing surface of burner pipe connecting flange is equal, upper and lower checkpoint to burner Whether the distance h3 of nozzle flange gasket face (surface) equal, check each 6 bolt hole of burner pipe connecting flange whether with respective body centre Line span centre is uniformly distributed.
2. under the premise of 1. an article measurement result is satisfied by requirement, to burner on the basis of 6 trepanning center line of pipe connecting flange 6 bolt hole of pipe connecting flange separates 4 heart lines, and upper and lower line in fundamental disagreement must be with trepanning center line centering.
3. two pieces of equal height cushion blocks 2 are put in two symmetrical pipe connecting flanges, 6 inner wall heart line respectively and at flange sealing surface, and Chalk line 4 is tightened on cushion block 2, measures 6 inner wall of pipe connecting flange to the distance between chalk line 4 h4, every heart line respectively surveys at 6 points, and surveys Platform 3 is measured to the distance between chalk line 4 h5,
4. removing cushion block 2, the bottom that two chalk lines 4 are directly placed to two symmetrical pipe connecting flanges 6 is united as one on line, is drawn Tight chalk line 4, using two 4 intersections of chalk line as the center of circle, whether measurement 6 sealing surface of pipe connecting flange to the distance between center of circle h6 respectively It is equal, it is used in combination square 8 to measure two intersecting lenses, checks whether two docking 6 center lines of pipe flange are vertical.
5. carrying out above procedure measurement to every a pair of symmetrical burner pipe connecting flange 6 successively, two symmetrical pipe connection methods can be checked With one heart whether orchid 6.
This measurement method has the following advantages compared with prior art:
1, meet symmetrical two flange of minor diameter, short distance tankage or measurement and the centering of symmetrical two take overs concentricity, It avoids influencing the processing performance of equipment because error is excessive.
2, survey tool is regular supplies, without in addition investment.
3, easy to operate, it measures size relatively accurate.
