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 the accompanying drawings, such as figure 1 As shown, the external structure diagram of the segmented cylindrical X-ray source is composed of five parts: expansion part, positive side pressure doubler sampling circuit area, X-ray tube placement area, negative side pressure doubler sampling circuit area, and sealing ring.

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

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 scan X-ray imaging such as medical treatment, flaw detection and safety inspection. Background technique [0002] At present, the main structure of the X-ray source for X-ray inspection equipment mainly has two forms, one is a polyhedral form formed by casting or welding of metal plates, and the other is a cylindrical form formed by processing. Regardless of the main body structure and shape, the main body of the X-ray source currently in practical applications in this field can be divided into a tube head and a high-voltage generating circuit in a single housing, and the tube head and high-voltage generating circuit belong to different housing components. And connect these two forms through high-voltage cables. The single shell form is to support the X-ray tube, voltage doubler rectifier circuit, sampling circuit, et...
