Description
Technical field
The present invention relates to a kind of x ray generator, relate in particular to a kind of sectional-drum-shape X-ray source that can be applicable in the X-ray-scanning images of object imaging field such as medical treatment, flaw detection, safety inspection.
Background technology
At present, x-ray inspection equipment mainly contains two kinds of forms with the agent structure shape of x-ray source, and a kind of is the polyhedron form of casting or sheet metal welding fabrication, and another kind is the cylinder form of machine-shaping.Though but adopt which kind of agent structure shape form, present x-ray source main body in the practical application of this area can be divided into tube head, the form of high-pressure generating circuit in single housing and tube head, high-pressure generating circuit and adhere to the different housings parts separately and be connected this two kinds of forms by high-tension cable.Single housing form is that X-ray tube, voltage doubling rectifing circuit, sample circuit etc. are supported by structural member, and fixing seal is at one independently in the housing.The major defect of the x-ray source of the single housing form of this kind is: housing adopts casting processing shaping rear interior cavity rough surface and is difficult for carrying out secondary operations; Owing to be single housing X ray energy full-shield protection, must adopt the stereotype of same thickness to make, the weight of x-ray source is increased greatly, be difficult for making high-octane x-ray source in the practical application; Because the restriction of version is difficult for realizing preferably the High-Voltage Insulation shielding and is not easy to maintenance.Tube head, high-pressure generating circuit split by the form that high-tension cable connects, have alleviated the weight of ray generation part, but owing to be to be connected by high-tension cable with high-pressure generating circuit, move, carrying is very inconvenient, often needs to disintegrate, and is very easy to produce fault.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of in light weight, be easy to process, can realize High-Voltage Insulation shielding and sectional-drum-shape X-ray source easy to maintenance.
Technical scheme of the present invention is achieved in that a kind of sectional-drum-shape X-ray source is mainly by swelling part, positive multiplication of voltage sample circuit district, limit, the X-ray tube rest area, marginal multiplication of voltage sample circuit district, seal socket five big parts are formed, place X-ray tube in the X-ray tube rest area, just, being provided with high pressure in the marginal multiplication of voltage sample circuit district takes place and sample circuit, wherein also comprise the supporting structure that assembling is required, the High-Voltage Insulation protector that the High-Voltage Insulation protection is required, X ray shielding protection spare and sealing ring, wherein swelling part is assemblied on the end face in multiplication of voltage sample circuit district, positive limit, positive multiplication of voltage sample circuit district, limit is assemblied on the left side of X-ray tube rest area, marginal multiplication of voltage sample circuit district is assemblied on the right side of X-ray tube rest area, and seal socket is assemblied in the right side in marginal multiplication of voltage sample circuit district.
Wherein X-ray tube is placed on the axis of whole sectional-drum-shape X-ray source, has guaranteed the quality uniformity of X ray in shooting angle.
Wherein the tube head of X-ray tube adopts flange to be connected with positive multiplication of voltage sample circuit district, limit and marginal multiplication of voltage sample circuit district, and high-voltage conducting wires passes oxidation stereotype protective baffle plate.
The sectional area emphasis of placing X-ray tube carries out X ray and reveals protection, and the multiplication of voltage sample circuit segmentation of positive and negative two ends can be carried out the generality protection; X-ray tube is positioned on the interior axis of cylindric sectional area, and does not have other high voltage components and parts in the zone; Positive limit multiplication of voltage sample circuit, marginal multiplication of voltage sample circuit symmetry two ends distribute.Single-ended asymmetric or symmetrical placement high pressure generation in two ends and sample circuit make the High-Voltage Insulation protection easily, are convenient to maintenance.
Compared with prior art the invention has the beneficial effects as follows:
1, the sectional-drum-shape structural design makes X ray exit direction flexibility and changeability, is applicable to that various types install and use;
2, the subregion that X ray is revealed is protected, and on the basis that guarantees fully effectively protection, has reduced complete machine weight widely, mobile, convenient in carrying, reliability height;
3, X-ray tube is placed on the axis of circular cylindrical shell body component, realized the quality uniformity of X ray in shooting angle, effectively improved the image processing effect in complete machine later stage,, made the High-Voltage Insulation protection realize easily owing to there are not other high voltage components and parts in the zone;
4, the multiplication of voltage sample circuit is placed at the symmetry two ends, makes the High-Voltage Insulation protection easily, is convenient to maintenance; Segmentation assembly type cylindrical in shape structure has reduced difficulty of processing, has reduced cost;
5, utilize the sectional-drum-shape X-ray source of this invention can make the high-energy x-ray source that 200kV is above and have actual use value.
