Conventional high-temperature high steam pipeline creep measurement points is installed, using the method for pipeline external surface circumference decile, it is determined that The position at creep measurement points center, and make measuring point seat centering.Each pair of measuring point in same section should be at perpendicular with conduit axis On same section.This method has following deficiency in implementation process:1st, the different creep measurement pointses in same section are it is difficult to ensure that same On one section;2nd, section with conduit axis it is difficult to ensure that vertical;3rd, Equal round girth and determination creep measurement points center are compared It is time-consuming.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, provides herein a kind of compacted for high temperature and high pressure steam pipeline Become the instrument of measuring point installation, it has the characteristics that high installation accuracy, simple to operate, efficiency high, repeatable utilization.
In order to achieve the above object, the present invention is realized in:
A kind of installation tool for jet chimney creep measurement points, including " mouth " shape framework, air-bubble leveling ruler, caliber regulation spiral shell Bar, U-typed pawl, the supporting screw rod of creep measurement points seat;For " mouth " shape frame hub on jet chimney, creep measurement points seat is screwed in creep measurement points On the supporting screw rod of seat, air-bubble leveling ruler is set on the side of " mouth " shape framework four, caliber adjusting screw rod is set in " mouth " shape framework surrounding, The caliber adjusting screw rod is located on two symmetry axis of " mouth " shape framework;Entirely " mouth " shape framework is fixed by U-typed pawl On pipeline.
The application method of the installation tool for jet chimney creep measurement points, including
Step 1, " mouth " shape frame hub on jet chimney,
Step 2, four creep measurement points seats are screwed on the supporting screw rod of creep measurement points seat,
Step 3, observation " mouth " shape frame upper side air-bubble leveling ruler, adjusting screw rod observation " mouth " shape frame upper side air-bubble leveling ruler, " mouth " shape frame upper side frame is adjusted to level,
Step 4, regulation caliber adjusting screw rod, creep measurement points seat are pressed on jet chimney, and adjust U-typed pawl " mouth " shape Framework is fixed perpendicular to jet chimney axis;
Step 5, creep measurement points seat and jet chimney welded.
This installation tool is applied to the pipeline of different tube diameters, efficiency high, can be applied to not by adjusting caliber adjusting screw rod Creep measurement points with caliber is installed, and can install a section creep measurement points simultaneously, rapidly and efficiently, is repeated and is utilized.
