Problems solved by technology

Because metal beryllium is usually pressed by powder metallurgy, the material is very brittle, has poor ductility, and is difficult to bend, so it is not suitable for the exit window material of X-ray tube with large radiation angle.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0024] like Figure 1-2 As shown, a titanium window structure X-ray tube includes a casing 1, an anode assembly and a cathode assembly 3, and the anode assembly includes an anode cap 2 and an anode target assembly 4, and the anode target assembly 4 and the anode cap 2 Welding (brazing); the anode assembly also includes a titanium window 5 which surrounds and is welded to the exit window of the anode cap 2 .

[0025] Further, the titanium window 5 is formed by bending a titanium strip with a thickness of 0.01-0.3 mm.

[0026] Further, the anode cap 2 adopts a thin-waisted anode cap structure with large ends and a small middle. ...

Abstract

The invention discloses an X-ray tube adopting a titanium window structure. The X-ray tube comprises a casing, an anode assembly and a cathode assembly, wherein the anode assembly further comprises an anode cap and an anode target assembly, and the anode target assembly is welded with the anode cap; the anode assembly further comprises a titanium window which surrounds and is welded at an exit window of the anode cap. A titanium tape is taken as the exit window of the X-ray tube, can realize equivalent inherent filtration with a beryllium window in a certain thickness, has good extensibility and welding performance and can be tightly connected with the anode cap with the large exit window, and the X-ray tube can output X rays at the large radiation angle and meets the demands of X-ray inspection equipment for the large radiation angle of rays.

Description

technical field [0001] The invention relates to an X-ray tube, in particular to an X-ray tube with a titanium window structure. Background technique [0002] At present, the existing X-ray tubes generally use metal beryllium as the exit window. Because metal beryllium is usually pressed by powder metallurgy, the material is very brittle, has poor ductility, and is difficult to bend. It is not suitable for the exit window material of X-ray tubes with large radiation angles. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide an X-ray tube with a titanium window structure. A titanium strip is used as the exit window of the X-ray tube. The titanium strip can achieve the equivalent inherent filtering of a beryllium window with a certain thickness and has good ductility And welding performance, so that the free bending of the titanium strip can be closely attached to the anode cap with a large-angle groove, and ...
