Description
Technical field
The utility model is the unsteady leather cup mechanism of the pipe leakage corrosion detector of online detection pipeline metal loss degree, relates to measurement and the pipe-line system technical field of measuring magnetic variable, thickness linear dimension.
Background technique
All can there be corrosion to a certain degree in buried steel pipeline, the particularly service time steel pipe more of a specified duration of operation, for guaranteeing the buried pipeline security of operation, all wants regularly pipeline to be done online corrosion usually and detects.Corrosive pipeline detects and all uses interior detection mode at present, mainly is flux-leakage detection method.No matter detection mode in which kind of must have leather cup mechanism on the detector, it is the power resources that detector moves in pipeline, and the detector that moves in gas pipeline and oil transport pipeline is not quite similar to the requirement of leather cup.In gas pipeline, drive leather cup and should select light-duty leather cup, main cause is that detector moves in gas pipeline, the running resistance of the detector huge variation that do not have through elbow, wall thickness change, valve etc. the time, otherwise gently then cause the detector fluctuation of service, heavy then may cause the damage of detector to pipeline.Abroad had about the huge acceleration of detector and pipeline was hit the report of wearing.The tension force of leather cup is the main cause that causes the detector running resistance to increase.In addition, be to guarantee the security of operation of pipeline, the design of leather cup should guarantee to produce earial drainage under certain pressure, like this, in case that card takes place in detector is stifled, pipeline can be owing to pressure does not increase too high booster or stopping transportation.And existing leather cup mechanism is because unreasonable structure, and leather cup is rapid wear not only, easily causes the detector fluctuation of service, and the tension force of leather cup is big, and easily card is stifled, and dynamic performance is not good enough.
The model utility content
The purpose of this utility model is the unsteady leather cup mechanism of good, the durable pipe leakage corrosion detector of dynamic performance of a kind of online detection pipeline metal loss degree of design.
Leather cup requires to be designed to manage internal interference and cooperates, and the main consideration of leather cup design is to guarantee that it always can keep in touch with pipe wall, and the remaining quality problems that need to consider are that it is flexible.Require leather cup in certain caliber scope, to the local deformation bore, provide enough driving forces from largest tube internal diameter (tolerance limit); But must possess enough flexiblely, so that overturn (for example the valve in the pipeline is partly closed) when detector blocks, flowing in the pipeline will can not interrupted fully.Therefore, must consider the section shape of hardness, the leather cup/resistance of inner tube wall generation and the thickness of definite leather cup of leather cup material.
In view of the above, structure of the present utility model is that leather cup 4 is fixed on the relocation mechanism as shown in Figure 1.Relocation mechanism is made up of leather cup float plate 5, leather cup floating shelf end plate 6, leather cup floating shelf 8, screw 9, screw 10, ring leather cup floating shelf 8 is linked by a plurality of screws 10 and leather cup floating shelf end plate 6, and between leather cup floating shelf 8 and leather cup floating shelf end plate 6, leave annular space, be sandwiched in ring leather cup float plate 5 in the space and become loose fit, and that leather cup 4 is clipped between leather cup platen 3 and leather cup float plate 5 outward edges by a plurality of double-screw bolts 1, locking nut 2 is fixing, and whole relocation mechanism is fixed on the detector body by a plurality of screws 9, screw 10.
For wear-resisting, respectively add a wear-resisting wearing plate 7 in two inboards, outer end of leather cup floating shelf end plate 6 and leather cup floating shelf 8, it is to be made by polytetrafluoroethylmaterial material.
4 one-tenth hollow bowls of leather cup (dish) shape wherein, the transition of the bowl end to bowl group is circular arc, makes with polyurethane material, and hardness is that international rubber hardness degree grade IRHD A-D ratio-10 is to 100 degree.
Wherein double-screw bolt 1 adopts stud; Locking nut 2 adopts 2 type non-metallic insert locking nuts; Screw 9, screw 10 adopt hexagon socket cap head screw.
The utility model is because leather cup 4 is fixed in the outward edge of leather cup float plate 5, and leather cup float plate 5 is clipped in the space between leather cup floating shelf 8 and the leather cup floating shelf end plate 6, and slip that can two degrees of freedom, just can make leather cup 4 in pipeline, do moving of upper and lower, left and right, to improve the passing capacity in pipeline.
Therefore the utility model can improve the passing capacity of detector in pipeline greatly because leather cup 4 is fixed on the relocation mechanism; And leather cup 4 can provide enough driving forces, can overturn when detector blocks again, guarantees the security of operation of pipeline, has improved the dynamic characteristic of detector greatly.
