Abstract
The utility model provides a guiding sleeve and sealing sleeve assembly suitable for the defectoscopy of a HRP model defectoscope, which provides a better solution for the requirement of the smaller steel pipe vibration value of the novel through type ultrasonic defectoscope during the defectoscopy. The guiding sleeve and sealing sleeve assembly comprises the following six parts: an inlet guiding sleeve, an outlet guiding sleeve, a PS1 inlet sealing sleeve, a PS1 outlet sealing sleeve, a PS2 inlet sealing sleeve and a PS2 outlet sealing sleeve. The guiding sleeve and sealing sleeve assembly is characterized in that higher precision is provided to be matched with the probe of the steel pipe defectoscope, the vibration value during the transmission of the steel pipe is maintained within an allowed range for the probe, the probability of misreport and failed reporting is reduced, and the production rate of the defectoscope is greatly improved; moreover, by changing the material, the cost for the spare part is reduced, and good economic benefit can be achieved.
Description
Technical field
The utility model relates to a kind of guide pin bushing, seal cartridge assembly of the HRP of being applicable to type ultrasonic flaw-detecting machine.
Background technology
Because HRP type ultrasonic flaw-detecting machine is a kind of novel through ultrasonic test equipment, inspection speed is fast, highly sensitive when being characterized in detecting a flaw.But the steel pipe that requirement is detected a flaw is in operation and keeps stability high, and amount of jitter is minimum.And present sealing shroud, the inlet guide pin bushing is with PS1 inlet seal cover, between PS1 exit seal cover and the PS2 inlet seal cover, gap value is in various degree arranged all between PS2 exit seal cover and the outlet guide pin bushing, can not make tested steel pipe in the range of control of guide pin bushing and sealing shroud in the inner whole process of probe holder.And the specification of each several part sealing shroud existing problems, can't make tested steel pipe maintain minimum amount of jitter in that roller-way is in service, well beyond the scope that requires of ultrasonic flaw-detecting machine at all.In this case, the phenomenon failing to report, report by mistake very easily appears.Be directed to this kind situation, need redesign defectoscope guide pin bushing, seal cartridge assembly, reduce steel pipe operation amount of jitter.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of guide pin bushing, seal cartridge assembly of the HRP of being applicable to type ultrasonic flaw-detecting machine, so that tested steel pipe amount of jitter in the middle of moving fast reaches the scope that can control, the phenomenon of failing to report, reporting by mistake appears in the minimizing flaw detection.
For achieving the above object, technical solution of the present utility model provides a kind of guide pin bushing, seal cartridge assembly of the HRP of being applicable to type ultrasonic flaw-detecting machine, wherein: described guide pin bushing, seal cartridge assembly include inlet guide pin bushing, outlet guide pin bushing, PS1 inlet seal cover, PS1 exit seal cover, PS2 inlet seal cover, PS2 exit seal cover, described guide pin bushing, seal cartridge assembly are interior hollow cylindrical pipe fitting, the interlude of described inlet guide pin bushing and outlet guide pin bushing is the cylindrical form interior surface of control steel pipe amount of jitter, and their two ends are cone-shaped inner surface; The entrance of described PS1 inlet seal cover and PS2 inlet seal cover is cone-shaped inner surface, and their other end is provided with the outside surface chamfering; The outlet section of described PS1 exit seal cover and PS2 exit seal cover is cone-shaped inner surface, and their other end is provided with the inside surface chamfering.
Effect of the present utility model is that guide pin bushing is used nonmetallic materials instead, has saved manufacturing expense.Because guide pin bushing is designed to nonmetallic materials, be convenient to again change; So the interior hole dimension of guide pin bushing is less than sealing shroud, by according to different steel pipe sizes, regulation different size guide pin bushing, sealing shroud are to reach the purpose of control steel pipe amount of jitter, and the probability of reduced wrong report in the flaw detection, failing to report has been obtained good economic benefit.
