The high-vacuum cavity provided by the utility model solves the problem of complexity in the prior art, ensures that repeated contrast tests are performed in a vacuum environment, is simple in operation, reduces the experiment waiting time, and can realize accurate positioning of the experiment device at the same time.
Description
Technical field
The utility model relates to the vacuum system field, is specially a kind of high vacuum cavity that can be used for Experiments of Optics rotation switching.
Background technology
Experiments of Optics need to occur in clean vacuum system, consider accuracy and the anti-interference of experiment, Experiments of Optics generator first, second can not be installed in vacuum system simultaneously, Experiments of Optics generator first, second need to be arranged in vacuum system respectively.Yet when Experiments of Optics generator first, second is carried out to the repetition contrast experiment, repeatedly open vacuum tank, can destroy vacuum environment, experiment simultaneously is very complicated, and the stand-by period is longer, for repeating contrast test, bring very large difficulty.Therefore Experiments of Optics generator first, second is arranged on respectively in two separate vacuum Cang Jia, second, realizes the independent experiment of Experiments of Optics generator first, second by the switching to vacuum Cang Jia, second.
Because high-vacuum tube route stainless steel is made, do not possess larger strain.Therefore when carrying out the switching of vacuum Cang Jia, second, need the central cavity of a vacuum cavity as rotation switching location, under the prerequisite that does not affect beam direction, carry out the switching of vacuum Cang Jia, second, thereby realize learning the independent experiment of experiment generator first, second.
The utility model content
The purpose of this utility model is to provide a kind of high vacuum cavity that can be used for Experiments of Optics rotation switching, with complexity and the long problem of stand-by period that solves prior art.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of high vacuum cavity that can be used for Experiments of Optics rotation switching, it is characterized in that: include triangle vavle, triangle vavle wherein on three walls, be respectively equipped with a welding bench, each welding bench is provided with a through hole, three through holes mutually run through in triangle vavle, the center line of three through holes intersects mutually, one of them through hole is as main optical path, another two through holes are as secondary light path, be welded with one section stainless steel tube on each welding bench, the mouth of pipe of each stainless steel tube is respectively facing to its corresponding through hole, the other end of each stainless steel tube is welded on respectively the tail end of a high vacuum metal sealing flange.
Described a kind of high vacuum cavity that can be used for Experiments of Optics rotation switching, it is characterized in that: the welding manner between described stainless steel tube and welding bench, high vacuum metal sealing flange is argon arc welding.
Operation principle of the present utility model is:
Two secondary light paths are respectively secondary light path first, secondary light path second, and triangle vavle is arranged on whirligig, drives the rotation of triangle vavle by whirligig.Triangle vavle can be changed to vacuum Cang Jia, second rotary cutting on the optical main axis of vacuum line, can realize accurate location simultaneously.Main optical path adopts stainless steel tube and high vacuum metal sealing valve to form, and by high vacuum metal sealing valve, realizes installing with the sealing of front end vacuum pipe.Secondary light path first adopts stainless steel tube and high vacuum metal sealing valve to form, and by high vacuum metal sealing valve, realizes installing with the sealing of vacuum Cang Jia.Secondary light path second adopts stainless steel tube and high vacuum metal sealing valve to form, and by high vacuum metal sealing valve, realizes installing with the sealing of vacuum storehouse second.
High vacuum cavity of the present utility model requires design, manufactures according to vacuum technique, in cavity, can realize high vacuum environment.While being switched between secondary light path first, secondary light path second, can be unimpeded from the light beam of primary optical axis, can not be subject to stopping of cavity inner wall.
The utility model has the advantages that:
The utility model is repeated rotation switching by triangle vavle and major and minor light path thereof, has guaranteed that the repetition contrast test carries out under vacuum environment, simple to operate, has reduced the experiment stand-by period, the accurate location that can realize experimental provision simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of high vacuum cavity that can be used for Experiments of Optics rotation switching, include triangle vavle 1, main optical path 2, secondary light path first 3, secondary light path second 4, be designed with welding bench 5 on triangle vavle 1 wall, welding bench 6, welding bench 7, be designed with three through holes that mutually run through in triangle vavle, Plane Angle between three through hole center lines is determined by design angle, main optical path 2 includes high vacuum metal sealing flange 8 and stainless steel tube 9, high vacuum metal sealing flange 8 tail ends and stainless steel tube 9 one ends weld by argon arc welding, welding bench 5 on the other end of stainless steel tube 9 and triangle vavle welds by argon arc welding, secondary light path first comprises high vacuum metal sealing flange 10 and stainless steel tube 11, and high vacuum metal sealing flange 10 tail ends and stainless steel tube 11 1 ends weld by argon arc welding, and the welding bench 6 on the other end of stainless steel tube 11 and triangle vavle welds by argon arc welding, secondary light path second comprises high vacuum metal sealing flange 12 and stainless steel tube 13, and high vacuum metal sealing flange 12 welds by argon arc welding with stainless steel tube 13 1 ends, and the welding bench 7 on the other end of stainless steel tube 13 and triangle vavle welds by argon arc welding.
