Abstract
The utility model discloses a vacuum isolation window for transmitting microwave power. The vacuum isolation window consists of a left flange (6), a right flange (5) and a sealing medium component, wherein the sealing medium component is connected with the left flange (6) and the right flange (5) through a connecting ring (3) and a water jacket (4) and is formed by sealing an alumina ceramic chip (1) and a metal seal sleeve (2); and a molybdenum wire (8) is wound at the periphery of a molybdenum belt (7) of the metal seal sleeve (2). The vacuum isolation window has the advantages that: the vacuum isolation window is simple in structure and convenient to use, can make microwave power pass through and can be sealed and isolated into vacuum; when klystrons or accelerating tubes are replaced, a waveguide system on the rear side of the vacuum isolation window for transmitting the microwave power still keeps the vacuum state, so that the efficiency is greatly improved.
Description
Technical field
The utility model relates to microwave technical field, refers to a kind of vacuum insulating window of Transmission Microwave power particularly.
Background technology
At present; Accelerator is used in fields such as medical treatment very extensively; But during owing to the work of the accelerating tube on the accelerator, radiant quantity is big, need be installed on the special field of safeguard procedures; Microwave power source is far to the distance of accelerating tube, so microwave power is very long from the transmission waveguide system that microwave power source is transported to accelerating tube; The power source (klystron) that on all kinds of accelerators such as irradiation accelerator, medical accelerator, uses all has certain life-span; Sometimes also can unexpectedly damage; Needed the replacement klystron after klystron lost efficacy, when klystron was dismantled, the whole wave guide system of klystron to accelerating tube all can expose atmosphere; Accelerating tube on the medical accelerator is the integral device of assembly welding mostly, if the accelerating tube on the accelerator lost efficacy, needs the replacement accelerating tube, and when accelerating tube was dismantled, the whole wave guide system from the accelerating tube to the klystron can expose atmosphere equally; No matter be to change klystron, still accelerating tube all will vacuumize in the whole transmission waveguide system again, and is long owing to Wave guide system, need take a long time, and could the vacuum in the Wave guide system be extracted into satisfactory vacuum degree.
The utility model content
The purpose of the utility model is exactly the vacuum insulating window of a kind of Transmission Microwave power that will provide a kind of and change conveniently, not need to vacuumize again.
For realizing above-mentioned purpose; The vacuum insulating window of a kind of Transmission Microwave power that the utility model designed; Constitute by left flange 6, right flange 5 and sealing medium assembly; The sealing medium assembly is connected with right flange 5 with left flange 6 through connecting ring 3, water jacket 4, and the sealing medium assembly is made up of alumina ceramic chip 1 and metallic seal sleeve 2; Molybdenum band 7 peripheries of metallic seal sleeve 2 are wound with molybdenum filament 8.
The advantage of the utility model is: the vacuum insulating window of a kind of Transmission Microwave power that is designed is simple in structure, easy to use, can allow microwave power pass through, again can the seal vacuum; When changing klystron or accelerating tube, the Wave guide system of the vacuum insulating window back of Transmission Microwave power still can keep vacuum state, therefore; After having invented this utility model; No matter be to change klystron, or accelerating tube, do not need to vacuumize again in the whole transmission waveguide system; Shortened the time of changing klystron or changing accelerating tube widely, greatly raised the efficiency.
Description of drawings
Fig. 1 is the structural representation of the vacuum insulating window of Transmission Microwave power;
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:
The vacuum insulating window of a kind of Transmission Microwave power as shown in Figure 1 comprises left flange 6 and right flange 5, and the sealing medium assembly; The sealing medium assembly is through connecting ring 3, water jacket 4 and left flange 6 and 5 welding of right flange; The sealing medium assembly is formed by alumina ceramic chip 1 and 2 sealing-ins of metallic seal sleeve, and the alumina content of alumina ceramic chip 1 is 95% to 97.6%, and tighten with molybdenum filament 8 molybdenum band 7 peripheries of metallic seal sleeve 2; Two adpting flanges, the normally monoyang and monoyins at two ends.With border operating position factually, also can manufacture two sun or jack to jack adapter, through the screw of two adpting flanges, realize and the docking of various components and parts with bolt.
On all kinds of accelerators, between power source (klystron) and transmission waveguide, be connected the vacuum insulating window of this Transmission Microwave power, just can open the vacuum insulation of the Wave guide system of this vacuum insulating window back.When therefore changing klystron, the Wave guide system of the vacuum insulating window back of Transmission Microwave power still can keep vacuum state.Be connected this vacuum insulating window between same transmission waveguide and the accelerating tube, just can open the vacuum insulation of the Wave guide system of this vacuum insulating window front.When changing accelerating tube, the Wave guide system of the vacuum insulating window front of Transmission Microwave power still can keep vacuum state, but the vacuum insulating window of this Transmission Microwave power can not influence the transmission of microwave power.
Therefore, invented the vacuum insulating window of this utility model Transmission Microwave power after, no matter be to change klystron, or accelerating tube, do not need to vacuumize again in the whole transmission waveguide system.Shortened the time of changing klystron or changing accelerating tube widely.General replacement once can be saved 2 to 3 day time.Greatly put forward the service efficiency of having done accelerator.
In many other microwave transmission systems, the vacuum insulating window of all available this utility model Transmission Microwave power is made vacuum insulation, and the replacing of instant microwave components and parts makes things convenient for the maintenance and the maintenance of machine.
The foregoing description is a preferred implementation of the present invention; But execution mode of the present invention is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within protection scope of the present invention.
