Technical field
The present invention relates to pipe detection field, and in particular to the pipeline quality detection means based on spectral technique.
Background technology
Pressure pipeline refers to all pipelines for bearing internal pressure or external pressure, regardless of medium in its pipe.Pressure pipeline is pipe
A part in road, pipeline are to convey, distribute, mix, separate, discharge, measure, control and prevent flow of fluid, by
Pipe, pipe fitting, flange, bolt connection, pad, valve, other component parts or pressure-containing parts and set of bearings into assembly.
Because pressure pipeline needs to bear very big fluid pressure, progress XRF inspection regular to pressure pipeline is needed when in use
Survey, exclude potential safety hazard.
But the XRF detector of existing portable hand-held formula is when in use, power very little, when X ray is in pipeline
When diffusing reflection occurs for surface, the spectral signal received is very faint so that testing result is not accurate enough.
The content of the invention
The technical problems to be solved by the invention be the XRF detector of existing portable hand-held formula when in use,
When in pipe surface diffusing reflection occurs for X ray, the spectral signal received is very faint so that and testing result is not accurate enough,
Purpose is to provide the pipeline quality detection means based on spectral technique, solves the above problems.

4th spectral receiver；The disk body is shaped as cylinder, and X-ray emitter, the first spectral receiver, the second spectrum connect
Device, the 3rd spectral receiver and the 4th spectral receiver is received to may be contained within end face of the disk body away from cross bar；The X-ray emission
The axis of device overlaps with the axis of disk body, and the first spectral receiver, the second spectral receiver, the 3rd spectral receiver and the 4th
Spectral receiver is arranged to remote by entering to the distance of X-ray emitter；The spectral collector is electrically connected to control device；Institute
The diameter for stating disk body uses 30~60cm.
In the prior art, the XRF detector of portable hand-held formula when in use, power very little, when X ray is in pipeline
When diffusing reflection occurs for surface, the spectral signal received is very faint so that testing result is not accurate enough.During present invention application,
When needing to carry out x-ray fluorescence analysis to pipeline, car body is pushed at pipeline, due to being delivered by carrier of car body
Rather than hand-held, it is possible to carry the larger high power x-ray generator of quality；By spectral collector alignment pipe
Road, by control device unlatching spectral collector, the X-ray emitter in spectral collector launches X ray, X ray to pipeline
Diffusing reflection occurs on pipeline, because disk body is arranged to cylinder, and the first spectral receiver, the second spectral receiver, the 3rd
Spectral receiver and the 4th spectral receiver are arranged to remote by entering to the distance of X-ray emitter, so that irreflexive X
It when ray is covered in card, can largely be gathered, improve the intensity of the spectral signal received, so that detection
As a result it is more accurate.
Further, first spectral receiver, the second spectral receiver, the 3rd spectral receiver and the 4th spectrum connect
The quantity for receiving device be two and more than, and the first spectral receiver, the second spectral receiver, the 3rd spectral receiver and the 4th
The quantity of spectral receiver is identical.
Further, first spectral receiver, the second spectral receiver, the 3rd spectral receiver and the 4th spectrum connect
The distance that the area of receipts device each arrives X-ray emitter to it is directly proportional.
During present invention application, the first spectral receiver, the second spectral receiver, the 3rd spectral receiver and the 4th spectrum connect
The distance that the area of receipts device each arrives X-ray emitter to it is directly proportional, for example the area of the first spectral receiver is 1cm2, away from
From being 1cm with a distance from X-ray emitter, the area of the second spectral receiver is 5cm2, the distance apart from X-ray emitter is
5cm, by that analogy.Due to more remote apart from X-ray emitter, irreflexive X-ray intensity is weaker, then is arranged such spectrum acquisition
After device, the spectral receiver away from X-ray emitter can also effectively gather the spectrum of X ray, improve accuracy of detection.
Further, X ray generator is set in the car body, and the outer wall of car body sets lead interlayer；The X ray
Generator is electrically connected to control device and X-ray emitter.
Further, the thickness of the lead interlayer is 10~15cm.
In the prior art, the x-ray fluorescence analyzer of hand-held when in use, can produce radiation, be set because hand-held limits
Standby quality, causes the radiation of the x-ray fluorescence analyzer of hand-held can not be effectively isolated, and caused radiation, can not more than 0.02mSy/h
Long-term use, long-term use can influence user health.During present invention application, X ray generator is arranged in car body, not only may be used
To carry more powerful X ray generator, while lead interlayer is set on car body, when the thickness of lead interlayer is 15cm
When, car body external detection to radiation value be about 0.05 μ Sy/h, even if user for a long time use, the dose of radiation of 1 year
No more than 0.15mSy, well below internationally recognized personal security's Dose standard 20mSv, so as to improve the security of equipment.
The present invention compared with prior art, has the following advantages and advantages：
Pipeline quality detection means of the invention based on spectral technique, the intensity of the spectral signal received is improved, from
And make it that testing result is more accurate.
