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

Ripple glass bulb X-ray tube
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.
Description of the drawings

Structural representations of the Fig. 2 for the X-ray tube of the embodiment of the present invention 2.
Specific embodiment
Below with reference to accompanying drawing, the invention will be further described, it should be noted that the present embodiment is with this technology side Premised on case, detailed embodiment and specific operating process are given, but protection scope of the present invention is not limited to this reality Apply example.
Embodiment 1
Fig. 1 show the ripple glass bulb X-ray tube of 250kV supertension.Including glass shell 101, cathode assembly 103 and sun Pole component 102, the outer surface of the glass shell 101 are provided with bellows-shaped structure 1011.
Further, the two ends 1012 of the glass shell 101 are provided with flat cylindrical structure, and respectively with the anode unit 103 sealing-in of part 102 and cathode assembly.
Further, the thickness of the glass shell 101 is 1.0~3.0mm.
Further, on the glass shell 101 with ray eye point 104 just to position using seamlessly transitting structure 105。
Negative and positive interpolar powers up 250kV high pressure, and ray tube working beam is 1mA.Test result shows:Under this Parameter Conditions Can continuous-stable work, meet rigors of the real time scan working method to device micro discharge.
Embodiment 2
Fig. 2 show the ripple glass bulb X-ray tube of 320kV supertension.Including glass shell 201, cathode assembly 203 and sun Pole component 202, the outer surface of the glass shell 201 are provided with bellows-shaped structure 2011.
Further, the two ends of the glass shell 201 are provided with flat cylindrical structure 2012, and respectively with the anode unit 203 sealing-in of part 202 and cathode assembly.
Further, the thickness of the glass shell 201 is 1.0~3.0mm.
Further, on the glass shell 201 with ray eye point 204 just to position using seamlessly transitting structure 205。
Negative and positive interpolar powers up 320kV high pressure, ray tube working beam 1mA.Test result shows:The energy under this Parameter Conditions Enough continuous-stable work, meets rigors of the real time scan working method to device micro discharge.
250kV is anode construction from the different of 320kV X-rays tubular construction maximum, as shown in Fig. 1,2 102 and 202; Purpose is to ensure that glass bulb meets different pressure demands along surface-potential gradient.
The ripple glass bulb X-ray tube operation principle:Cathode assembly focus emission thermoelectron, thermoelectron are high by anode assemblies Piezoelectricity field action high velocity bombardment plate target produces required X-ray, and corrugated glass shell plays support negative and positive the two poles of the earth and keeps pipe interior The effect of vacuum.
