Description

The repair method of ring flange in a kind of x ray generator
Technical field
The present invention relates to x ray generator technical field, more particularly, it relates to the repair method of ring flange in a kind of x ray generator.
Background technology
In engineering construction construction, often the building materials such as pipeline are detected a flaw. X-ray inspection is one of conventional flaw detection means, and x ray generator, can because the damage of its internal high pressure bag need to carry out laid-up as one of the important composition parts of x-ray inspection.
The flange plate type that the pipe bucket of existing x ray generator is traditional seals structure, and namely pipe bucket cylinder upper end open is provided with ring flange, and the high voltage package of x ray generator is fixed on below ring flange by support. The fixed form of support adopts threaded, namely screwed hole is provided below at ring flange, support arranges bolt, and bolt makes support be fixed under ring flange with matching of screw thread.
When changing the high voltage package damaged, it is necessary to the bolt on repeated disassembled and assembled support. Screwed hole on ring flange there will be breakage in repeated disassembled and assembled process, and bolt can not installed because the silk tooth in screwed hole skids, it is necessary to the screwed hole of ring flange is placed under repair. The repair method generally taked is to be strengthened in the aperture of screwed hole with screw tap, re-starts fixing with bigger bolt. The aperture of screwed hole increases, and the degree of depth of screwed hole is not deepened because of the restriction by flange thickness, and the intensity of fixing high voltage package does not then reach designing requirement. Ring flange, through repairing, also can only be replaced with being necessary for several times again, the Financial cost frequently changing increase engineering construction of ring flange. This kind of repair method does not tackle the problem at its root.
