Problems solved by technology

The main disadvantages of the X-ray source in the form of a single shell are: the surface of the inner cavity is rough after the shell is formed by casting, and it is not easy to carry out secondary processing; Made of lead plate, the weight of the X-ray source is greatly increased, and it is not easy to make a high-energy X-ray source in practical applications; due to the limitation of the structure, it is not easy to achieve high-voltage insulation shielding and it is not easy to maintain
The tube head and the high-voltage generating circuit are separated and connected by a high-voltage cable, which reduces the weight of the radiation-generating parts. However, since the high-voltage generating circuit is connected by a high-voltage cable, it is very inconvenient to move and carry, and it often needs to be disassembled, which is very easy to generate radiation.

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with accompanying drawing, as figure 1 As shown, the schematic diagram of the external structure of the segmented cylindrical X-ray source is composed of five parts: the expansion part, the positive side pressure doubler sampling circuit area, the X-ray tube placement area, the negative side voltage doubler sampling circuit area, and the sealing ring.

[0030] Such as figure 2 As shown, the expansion part 1 is assembled from a plurality of parts such as a sealing flange and a telescopic capsule to form a closed and telescopic volume, which is assembled in the positive pressure doubler sampling circuit area 2 through a sealing ring 6 and screws. On the end face, it can relieve the need of volume change due to thermal expansion and cold contraction of insulating oil; positive side voltage doubler sampling circuit area 2 is composed of sampling circuit board 8, voltage doubler circuit board 9, ...

Abstract

Being applicable to X ray scan imaging device in areas of safety check, medical examining, non destructive test in industry etc, the disclosed X ray source is composed of expansion part, positive dual voltage sampling circuit area, X ray tube placement area, negative dual voltage sampling circuit area and seal socket. The positive and negative dual voltage sampling circuit areas are distributed on two ends symmetrically. X ray tube is located on central line. Features are: easy of preparing protection of high voltage insulation, convenient for maintenance, reduced weight and evenness of quality within emergence angle of X ray.

Description

technical field [0001] The invention relates to an X-ray generator, in particular to a segmented cylindrical X-ray source which can be applied in the field of line scanning X-ray imaging such as medical treatment, flaw detection and safety inspection. Background technique [0002] At present, there are two main structural shapes of the X-ray source used in X-ray inspection equipment, one is a polyhedron formed by casting or welding of metal plates, and the other is a cylindrical form formed by processing. But no matter what kind of main body structure and shape is adopted, the main body of the X-ray source in the actual application in this field can be divided into the form that the tube head and the high-voltage generating circuit are in a single shell, and the tube head and the high-voltage generating circuit belong to different shell parts And connect these two forms by high voltage cables. In the form of a single housing, the X-ray tube, voltage doubler rectifier circui...
