Description
Technical field
The utility model relates to boiler plant fields, especially a kind of to be used for the radiographic X backshield of small-bore pipe
Device.
Background technique
Radiography refers to and uses X-ray or gamma-rays to detect material and workpiece and using radiographic film as record
A kind of lossless detecting method of medium and display methods.Radiography detection is passed through using X-ray and gamma-ray numerous characteristics
The decaying that the photosensitive related X-ray on radiographic film or gamma-rays occur in tested material or workpiece is observed and recorded to become
Change, to determine that the inside of tested material and workpiece whether there is defect, thus not destroying or not damaging tested material and workpiece
In the case where, assess its quality and use value.
In current thermal power plant, most of to use overcritical or extra-supercritical unit, boiler coils, water-cooling wall are equal
It is designed using path thick-walled pipe, this brings certain difficulty to the radiography of weld seam.Small-bore pipe weld seam because its caliber compared with
Small, when radiography, pipe itself can not cover film completely, this just makes the glue on egative film close to small-bore pipe marginal portion
Piece causes base density plus fog degree to increase clarity reduction, the especially photograph of weld seam shoulder since scattered rays influences to generate side erosion effect
Phase quality, which will receive, to be seriously affected.
To avoid scattered rays side from losing the influence of effect, current conventional method is that square hole will be scratched among lead shield, then will
Lead shield is placed between radiographic source and workpiece, and weld seam exposes from square hole, is shielded using lead shield to scattered rays.But this method lacks
Point is also more: it is then different for the small diameter tube aperture size of different-diameter, therefore need to make several lead shields with meet demand；Lead
Shield that harder ductility is bad, to the weld seam for having reinforcement, lead shield edge is easy to leak through ray；It can be seen that conventional method imaging effect
The disadvantages of difference, low efficiency, wasting of resources.
Utility model content
The utility model is that imaging effect is poor when solving traditional small-bore pipe radiography, low efficiency, the skill of the wasting of resources
Art problem is to provide a kind of for the radiographic X backshield device of small-bore pipe.
The technical scheme adopted by the utility model is including a pair of of relative spacing setting and the adjustable shield machine of spacing
Structure.Small-bore pipe needs compared to traditional different size scratch different square holes, the utility model among different lead shields
Two shielding bodies between the spacing radiographic X shielding demand of small diameter tube that is adjustable, therefore can satisfy plurality of specifications,
The versatility for improving device, reduces production cost, improves efficiency, and present apparatus structure is simple and convenient to operate, is easy to pacify
Dress.
Further, further including elastic clamping mechanism, the shielding body setting is opposed in elastic clamping mechanism
Two sides.Shielding body can be fixed on tested pipe fitting by one side of elastic clamping mechanism, on the other hand, since clamping device has
Elasticity, therefore the spacing between adjustable two shielding bodies, therefore the small diameter tube that can satisfy plurality of specifications is radiographic X
Shielding demand improves the versatility of device.
Further, the elastic clamping mechanism includes U-shaped steel and spring, U-shaped steel is connected by spring and shielding body
It connects.Manufacturing process is simple and convenient to operate, and cost is relatively low.
Further, the shielding body includes sequentially connected steel plate, stereotype and lead rubber slab, the U-shaped steel according to
It is secondary to be connect by spring, steel plate, stereotype and lead rubber slab with tested pipeline.Steel plate provides good rigid for entire shielding body
Property, it is located at shielding body outermost and is connect with elastic clamping mechanism；Stereotype provides good shield effectiveness for shielding body；Lead rubber
Offset plate has good flexibility, can fit closely with tested pipeline, is seamlessly connected shielding body and tested pipeline, avoids ray
From the slit source of pipeline edge.Shielding body has the weld seam of reinforcement that can also accomplish good shield effectiveness weld seam, so that
Shielding body is obviously improved the shield effectiveness of scattered rays.
Further, the steel plate is connect by welding with stereotype, stereotype is connect by adhesive with lead rubber slab.Steel
Plate is connect with stereotype by welding manner, and the hardness of shielding body is further increased, and lead rubber slab holds in the long-term use
Lead rubber slab is changed vulnerable to extrusion deformation, therefore by the way that adhesive is easy to connect.
The beneficial effects of the utility model are:
1, the utility model is used for the radiographic X backshield device of small-bore pipe, compared to traditional different size
Small-bore pipe needs scratch different square holes, the spacing between two shielding bodies of the utility model among different lead shields
The radiographic X shielding demand of small diameter tube that is adjustable, therefore can satisfy plurality of specifications, improves the versatility of device, reduces
Production cost improves efficiency, and present apparatus structure is simple and convenient to operate, is easily installed.
2, the shielding body includes sequentially connected steel plate, stereotype and lead rubber slab, and steel plate is that entire shielding body mentions
For good rigidity, it is located at shielding body outermost and is connect with elastic clamping mechanism；Stereotype provides good screen for shielding body
Cover effect；Lead rubber slab has good flexibility, can fit closely with tested pipeline, make shielding body and the seamless company of tested pipeline
It connects, avoids ray from the slit source of pipeline edge, so that shielding body is obviously improved the shield effectiveness of scattered rays.
