Description
Technical field
The utility model relates to the angle probe that is used for the two-way flaw detection of steel pipe contact ultrasound wave, relates in particular to the detection of diameter of steel tube greater than pipe material more than the 60mm.
Technical background
It is one of detection means commonly used during steel pipe detects that UT (Ultrasonic Testing) detects, and enters the hyperacoustic variation that is detected workpiece such as steel pipe by ultrasonic probe emission and acceptance and realizes being detected the detection of workpiece.Generally adopt angle probe for diameter than the flaw detection of big steel pipe, angle probe be utilize compressional wave on wedge and workpiece interface wave mode conversion and in workpiece, produce a kind of probe of required shear wave wave mode.Regulation according to the 4.2nd of steel tube supersonic flaw detecting standard GB/T5777-96: the flaw detection of steel pipe contact method must be carried out two-way test, should carry out on two reverse directions of pipe when promptly detecting a flaw.Chinese patent 01253844.2 discloses the two-way angle probe of a kind of steel tube supersonic flaw detecting, and the more original single syncline probe efficient of this two-way angle probe doubles.But for the signal that guarantees probe can effectively import in the steel pipe, must apply couplant (machine oil) in steel tube surface, the method that generally adopts is that the flaw detection operator coats machine oil at the steel tube flaw detection position earlier at present, and then implement to detect a flaw, this method has not only increased flaw detection operator's workload, and flaw detection efficient is low, and because steel pipe is a curved surface, machine oil runs off very fast, the coupling effect of influence flaw detection.
Summary of the invention
The utility model has overcome the defective that existing steel tube flaw detection angle probe need manually be smeared couplant (machine oil), provide a kind of steel tube supersonic flaw detecting oil-filling type two-way angle probe, this angle probe can spray couplant, couplant is sprayed on steel tube surface, probe has the good coupling effect with steel pipe when guaranteeing steel tube flaw detection, can shorten the flaw detection time, improve flaw detection efficient, alleviate flaw detection operator labour intensity.
The utility model is achieved in that the two-way angle probe of a kind of steel tube supersonic flaw detecting oil-filling type, comprise that shell, tapered wedges, two groups of wafers, dampings absorb piece and electrode, one group of wafer that staggers mutually respectively is equipped with in band circular arc tapered wedges both sides, it is characterized in that oil storage box being housed at the opposite side of shell counter electrode, the external oil pipe of oil fuel tube is equipped with on oil storage box top, the oil storage box bottom has atomizer, and atomizer is a pancake.
In the two-way angle probe of above-mentioned steel tube supersonic flaw detecting oil-filling type, described oil storage box is close to angle probe shell one side, and oil storage box is pancake and joins together with shell.
The utility model is to have increased oil storage box on the basis of existing steel tube supersonic flaw detecting with two-way angle probe, oil storage box and angle probe shell are combined, when flaw detection, spray couplant in steel tube surface from oil storage box, improved the coupling effect of probe and steel pipe, reduce omission, the wrong report of flaw detection, reduce operation steps, alleviate the flaw detection labor intensity, shorten the steel tube flaw detection time, improve the flaw detection work efficiency.
