Embodiment
The utility model provides a kind of nozzle inner wall eccentric exposure support frame (hereinafter referred to as support frame), can be by Fig. 1
The source 8 of shown radiographic source is fixed in nozzle inner wall, makes its eccentric exposure suitable for ray detection.
As shown in Figure 2 to 4, support frame is provided with by top transverse slat 2, bottom transverse slat 3, Left-side support plate 1, Right side support
The frame structure that plate 4 surrounds, is additionally provided with foot support 5；The fulcrum of described one end of foot support 5 is arranged on Left-side support plate 1
The left side, the extension that the fulcrum of the other end is connected through a screw thread is arranged on the right of Right side support plate 4.
Wherein, top transverse slat 2 offers first through hole 21, for the source 8 in fixed RF source；Correspondingly, in institute
State bottom transverse slat 3 and offer the second through hole 31, for the pipeline (source is sent to source position by pipeline) in fixed RF source etc..
Afterwards, screwed foot support 5 is stretched out into tensioning, support frame is fixed to tested nozzle inner wall.During operation, pass through source 8
Eccentric exposure is carried out in tested nozzle interior.
