Space, on the other hand because the atomic structure of lead is more close, can be stopped part ray, reduce ray to operator
The injury of member, the setting of compensation block can increase to be compensated to ray, reduces the possibility that joint edge erosion effect occurs.
Further set：Is arranged with end cap on the described one end of main detection section away from auxiliary detection section, hold the external diameter of cap with
The internal diameter of pipe fitting is identical.
By using above-mentioned technical proposal, needed during due to detection by radiographic source centering, when the diameter of main detection section is less than
During the internal diameter of pipe fitting, the setting of end cap can help main detection section to be always positioned at the middle of pipe fitting, so as to facilitate operating personnel
Centering is carried out to radiographic source.
Preferably, the diameter of the compensation block is identical with holding the diameter of cap.
By using above-mentioned technical proposal, on the one hand the effect of compensation block is to reduce the possibility that side erosion occurs, on the other hand
Centering can be carried out to main detection section with abutting end cap, therefore the diameter of compensation block identical can make main detection section with the diameter of end cap
Center in pipe fitting.
Another object of the present utility model is to provide a kind of ray inspection machine, its have can special detection internal diameter exist
The advantage of 9.5mm~12.5mm pipe inside fillets.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of ray inspection machine, with any one above-mentioned ray inspection machine imaging frock.
In summary, the utility model has the advantages that：
Source rod can be placed in pipe fitting, and leave detection needed for gap, can reach special detection internal diameter 9.5mm~
The effect of 12.5mm pipe inside fillets, moreover it is possible to which the quality to imaging is detected, while the emission of ray can be reduced, is reduced
The ray damage healthy to operating personnel.
