Abstract
The utility model discloses an X-ray tube with various size focuses and two-member filaments. A filament is added on the basis of the single filament of the original size focuses to change the single into a set. The life of the filament is improved to one time. Consequently, the service life of the X ray tube is prolonged.
Description
The utility model relates to a kind of medicine equipment.
The rotating anode X-ray tube and the fixed anode X-ray tube of countries in the world production at present all adopt each filament of big or small focus, and when a filament damaged, function reduced half.When two filaments damaged, X-ray tube was scrapped, and it is the one of the main reasons that present X-ray tube damages.
The purpose of this utility model just is to provide the two group of a kind of novel big or small focus filament X-ray tube, and the life-span of filament is doubled.
The purpose of this utility model is achieved in that on the basis of original big or small focus filament, respectively add a filament, make a filament become one group of filament, four lines of size focus two groups of filaments formation common line that connects together, join by a lead and outside, and four end points of two groups of filament opposite sides, then be separately fixed on the nut, the outside joins fixing by the lead-in wire of two big or small focus filaments by two screws and nut, when a filament damages, lead-in wire is being screwed on another nut by screw, and another filament is played a role.
Be described in further detail below in conjunction with accompanying drawing: figure 1. for X-ray tube (1, for the rotarting anode target surface, 2, be glass shell, 3, be filament lead wire, 4, the cathode terminal cell bodies that are bumped into for two group filaments), 2. figure be the front view (1, for large focal spot filament 2, be little focus filament) of cathode terminal cell body.Figure 3. be circuit diagram (1, be the large focal spot filament, 2, be little focus filament, 3, be common line.
Claims (1)
- A kind of novel X-ray tube has anode, negative electrode, glass shell, big or small focus filament.Its feature just is that big or small focus filament is two group filaments.
