Description
Technical field
The utility model relates to sealing apparatus, in particular to the sealing-in lathe of a kind of metal and glass.
Background technique
CT machine is a kind of multiple functional condition detection instrument, and with the development of technology, CT machine is with high resolution and directly
See, accurate diagnosis effect and popularized, be widely used in medical field.CT bulb, also referred to as X-ray
Pipe, is the core component in CT machine, and for generating X-ray, the technical perfection of CT bulb whether directly affects the work effect of CT machine
Fruit.X-ray tube mainly includes anode, cathode and glass shell, and anode includes target disc, shaft, rotor and bearing, and cathode includes lamp
Silk, cathode taps and cathode stem.Its working principle is that: the filament made of tungsten wire can emit sufficient amount of electricity at high temperature
Son, as electron source；Under the forceful electric power field action formed between anode, cathode plus the high pressure by tens kilovolts to several hundred kilovolts,
Accelerate electronics and forms high-speed electron flow；The effect of anode is to attract electronics and accelerate electronics, and bang the electronics of high-speed motion
Hit target disc target surface, target surface is subjected to electron bombardment it is made sharply to be obstructed generating X-ray.The electrode system of entire X-ray tube is encapsulated in
In the glass shell of high vacuum, glass shell to support yin, yang the two poles of the earth and provide high-velocity electrons flight and high temperature filament it is normal
Vacuum environment necessary to working.
