Description
Technical field
The present invention relates to a kind of X-ray tube, and in particular to a kind of titanium window construction X-ray tube.
Background technology
Current existing X-ray tube is typically using metallic beryllium as exit window.Because metallic beryllium is typically with powder smelting
Gold compacting is formed, and material is very crisp, and ductility is very poor, it is difficult to carry out Bending Processing, and uncomfortable cooperation large radiation degree angle X-ray tube goes out
Penetrate window material.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of titanium window construction X-ray tube, is penetrated using titanium band as X
The exit window of spool, titanium band can be realized with the equivalent inherent filtration of certain thickness beryllium window and with good ductility and welding performance,
So as to realize with free bending being brought into close contact titanium with the anode cap with wide-angle groove, X-ray large radiation degree angle is realized
Output, meets x-ray inspection equipment to ray large radiation degree angle demand.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of titanium window construction X-ray tube, including shell, anode assemblies and cathode assembly, the anode assemblies are also included
Anode cap and anode target assembly, the anode target assembly are welded with the anode cap；The anode assemblies also include titanium window, institute
Titanium window is stated to surround and be welded at the exit window of the anode cap.
Further, the titanium window is formed by the titanium band bending of 0.01~0.3mm thickness.
Further, the anode cap is using the thin waist type anode cap that two ends are big, centre is small.
Further, the titanium band is pure titanium vacuum material.
Further, the outgoing groove width of anode cap is 3~5mm, and the thickness range at the exit window of anode cap is 4~6mm,
Titanium window is 14~16mm with the distance range of target center；
Further, titanium window is connected with anode cap by the way of spot welding adds and rushes nest.
The beneficial effects of the present invention are：
1st, titanium band has good ductility and welding performance, can be by free bending and the anode cap with wide-angle groove
It is brought into close contact, meets the ray demand that radiancy angle is not less than 100 °.
2nd, the characteristics of titanium has low atomic number, low-density, with certain thickness beryllium in 0.01~0.3mm thickness ranges
Window inherent filtration is equivalent, can produce the spectral distribution close with Conventional X-ray tubes, therefore using titanium window as exit window, can
To realize not interfered with while the output of X-ray large radiation degree angle the performance of X-ray tube.
3rd, effective deaeration can be realized using pure titanium vacuum material.
4th, thin waist type anode cap is prevented effectively from the electric discharge generation of welding titanium band tip burr, improves the high pressure of ray tube
Stability.
5th, (anode cap outgoing groove width scope is 3~5mm, sun to reduce anode cap outgoing groove width, increase titanium window and target center distance
Thickness range is 4~6mm at polar cap exit window, and titanium window is 14~16mm with the distance range of target center), titanium window is used with anode cap
Spot welding adds rushes work holdup skill connected mode, can effectively increase titanium band exit window thermal conduction characteristic, improves ray tube functional reliability.

Specific embodiment
Below with reference to accompanying drawing, the invention will be further described, it is necessary to explanation, the present embodiment is with this technology side
Premised on case, detailed implementation method and specific operating process is given, but protection scope of the present invention is not limited to this reality
Apply example.
As shown in Figure 1-2, a kind of titanium window construction X-ray tube, including shell 1, anode assemblies and cathode assembly 3, the sun
Pole component includes anode cap 2 and anode target assembly 4, and the anode target assembly 4 is welded (soldering) with the anode cap 2；It is described
Anode assemblies also include titanium window 5, and the titanium window 5 surround and is welded at the exit window of the anode cap 2.
Further, the titanium window 5 is formed by the titanium band bending of 0.01~0.3mm thickness.
Further, the anode cap 2 is using the thin waist type anode cap that two ends are big, centre is small.
Further, the titanium band is pure titanium vacuum material.
Further, as shown in figure 3, the outgoing groove width D of anode cap is 3~5mm, the thickness T at the exit window of anode cap
Scope is 4~6mm, and titanium window is 14~16mm apart from L scopes with target center, and titanium window is with anode cap by the way of spot welding adds and rushes nest
Connection.
The titanium band of 0.01~0.3mm thickness is chosen, can be realized and the equivalent inherent filtration of certain thickness beryllium window, and titanium band has
Good ductility and welding performance, can realize closely being connected with the anode cap with wide-angle groove, as Figure 4-Figure 6, sun
The groove 21 not less than 100 degree can be opened on polar cap, so as to realize that X-ray large radiation degree angle exports.In operating voltage 160kV, beam
Under conditions of stream 2mA, output of the X-ray radiation angle not less than 100 degree can be realized, meet x-ray inspection equipment big to ray
Radiancy angle demand.
The operation principle of titanium window construction X-ray tube：Cathode assembly focus emission thermoelectron, thermoelectron receives anode assemblies high pressure
Electric field action high velocity bombardment anode target assembly and produce X-ray.Anode cap can effectively stop that secondary electron is sputtered；Anode clevis is
X-ray exit portal, is capable of achieving the output of X-ray large radiation degree angle；Titanium window can ensure the abundant transmission of X-ray and stop secondary electron
Sputtering.
