Solid state encapsulation device of X light tube for X fluorescent spectrometer

Abstract

The invention relates to an X-ray tube solid packaging device, comprising an X-ray tube body (2), an inner hexagon screw (3), a sealed rubber flange (4), an end face sealed flange plate (5), an insulating oil (6) and an assembly glue (7); wherein, the inner surface of the end face sealed flange plate is bonded with at least one vacuum hole pressure-reducing rubber (11); the assembly glue (7) is evenly painted at one end (1) without reversed angles of vacuum hole pressure-reducing rubber (1); the vacuum hole pressure-reducing rubber (11) is in the middle of the end face sealed flange plate (5) with sealed ring-shaped slot section; the vacuum hole pressure-reducing rubber (11) comprises a rubber base (111) and a plurality of vacuum cavity (112) therein. Compared with the expansion capsule in the prior art, the vacuum hole pressure-reducing rubber of the invention does not bear the effect of sealing, and effectively reduces the phenomenon caused by that the fatigue deformation, aging, crack and break, etc. of the expansion capsule.

Description

X-ray tube solid packaging device used in X-ray fluorescence spectrometer technical field The invention relates to a sealing part of an X-ray tube used in an X-ray fluorescence spectrometer, in particular to a sealing device which adopts solid vacuum hole pressure-relieving rubber to assist in sealing the X-ray tube. Background technique At present, the oil-immersed sealed X-ray tube is mainly in the form of a rubber telescopic capsule, as shown in Figure 1, an insulating oil expansion part for an X-ray source. It consists of a shell, a sealing ring, a sealing flange, a telescopic capsule, a pressure ring, and a pressure ring. It is characterized in that the telescopic capsule is arranged in the shell, and its opening is outward, and one end is closed and integrated, and the other end is a The flanging plane form, the pressure ring ring and the pressure ring are sequentially arranged on the inner cylindrical surface of the flanging plane of the telescopic capsule, and the ...
