Abstract
The invention discloses a ripple glass bulb X ray tube. The ripple glass bulb X ray tube comprises a glass shell, a cathode component and an anode component. An external surface of the glass shell is provided with a corrugated structure. In the invention, a corrugated glass bulb is adopted; under a certain entire tube size, a glass bulb edge surface length is long and a glass bulb edge surface potential gradient is small; under a small entire tube size, creepage difficulty of glass bulb accumulation charges can be increased and a voltage withstanding level of an entire tube is improved so as to adapt to an extra high voltage requirement; and the X ray tube becomes an extra high voltage X ray tube.
Description
Technical field
The present invention relates to a kind of X-ray tube, and in particular to a kind of ripple glass bulb X-ray tube.
Background technology
Glass material of the shell mechanism of existing X-ray tube typically from surfacing, in general, X-ray tube tolerance
High-tension ability is closely related along face length and glass bulb diameter with glass shell (glass bulb), and glass bulb is longer along face length, its electricity
Potential gradient is less.Using the glass material of surfacing as shell mechanism, for specific demand extra-high pressure X-ray tube
When, its High-Voltage Insulation level need to could be improved using large-size glass shell, the overall dimensions of X-ray tube certainly will be increased so that
The mechanical performance of ray tube is reduced, and reduces the reliability and stability of work.
The content of the invention
For the deficiencies in the prior art, the present invention is intended to provide a kind of ripple glass bulb X-ray tube, the shell knot of X-ray tube
Structure adopts glass bulb (vacuum sealing glass shell), and is processed into bellows-shaped, in identical glass bulb under the length of face, ripple glass
Shell structure is more much smaller than smooth glass bulb physical dimension, then under the premise of same potential gradient, using ripple glass bulb structure energy
Effectively shorten homogeneous tube size such that it is able to less homogeneous tube size, and glass shell are kept under the resistance to voltage levels for improving glass bulb
With light quality, processing technology be simple, cheap feature.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of ripple glass bulb X-ray tube, including glass shell, cathode assembly and anode assemblies, outside the glass shell
Surface is provided with bellows-shaped structure.
Further, the two ends of the glass shell be flat cylindrical structure, and respectively with the anode assemblies and negative electrode
Component sealing-in.
Further, the thickness of the glass shell is 1.0～3.0mm.
Further, structure is seamlessly transitted with just adopting to position for ray exit direction on the glass shell.
The beneficial effects of the present invention is：
1st, using corrugated glass bulb, there is bigger glass bulb under certain homogeneous tube size along face length, less glass bulb is along face
Electric potential gradient, can increase the electric difficulty of climbing of glass bulb stored charge under less homogeneous tube size, improve the resistance to voltage levels of homogeneous tube, adapt to
The requirement of supertension, so as to become supertension X-ray tube.
2nd, the ripple glass bulb X-ray tube is to be applied to X-ray-scanning images of object to check equipment, and line scanning device requires that ray is
Fan-shaped distribution.X-ray inherent filtration is closely related with glass bulb thickness, if effective rays radiation position glass bulb is corrugated, can be because
Ray is different through thickness of glass, affects the inherent filtration of X-ray.By ray exit direction just to position using smooth
Transition structure, it is ensured that ray inherent filtration is consistent, meets X-ray energy spectrum Even distribution entails.
3rd, traditional glass shell X-ray tube is compared, homogeneous tube size can be greatly shortened using the X-ray tube of ripple glass bulb, be
High voltage radiographic source miniaturization creates conditions.
4th, under the premise of resistance to voltage levels are met, compared with conventional high-pressure X-ray tube, glass bulb contraction in length, the contracting of homogeneous tube volume
It is little, compact structure design is realized, the impact resistance of cast is effectively improved.
5th, two ends are flat cylindrical structure design so as to consistent with conventional pipe with the process for sealing of cathode and anode component, are had
Versatility and easy-operating feature.
