Because electric controller 812 electrical control in the vaccum pump motor 41 of aforesaid vacuum device 4 and the instrument container chamber 81 of instrument container 8 is connected, again because operation control panel 83 and electric controller 812 are electrically connected, thus by operator to the corresponding push-botton operation on electrical control electroplax 83, make vaccum pump motor 41 in running order, vacuum pump 42 is driven to work, air in deuterium treatment tank chamber 11 is treated tank lower sub 15 successively, extraction pipe 4211 and air-inlet of vacuum pump 421, until cause the external world by vacuum pump air outlet 422, when the vacuum tightness in deuterium treatment tank chamber 11 reach 100torr namely reach 1333.3Pa time, vaccum pump motor 41 quits work.Negative pressure state in deuterium treatment tank chamber 11 is shown by the data display screen 831 on operation control panel 83, because be provided with the sensor (not shown) for the pressure condition in perception deuterium treatment tank chamber 11 be electrically connected with electric controller 812 on deuterium treatment tank 1.
After aforementioned vacuum pump motor 41 quits work, the deuterium bottle valve 101 on the deuterium bottle 10 illustrated by Fig. 2 is opened by operator, deuterium in deuterium bottle 10 enters deuterium skirt 2, and the deuterium entered in deuterium skirt 2 controls ball valve 51, deuterium reducing valve 52, deuterium under meter 53 and deuterium magnetic valve 54 through the deuterium of opened condition successively and enters deuterium nitrogen mixed gas inlet tube 131.Meanwhile, though by nitrogengas cylinder valve that is not shown in operator's unlatching figure but that can understand completely according to professional general knowledge on the nitrogengas cylinder that, nitrogen in nitrogengas cylinder enters nitrogen skirt 3, and the nitrogen entered in nitrogen skirt 3 enters in deuterium nitrogen mixed gas inlet tube 131 through the nitrogen intake valve 55 of opened condition, nitrogen reducing valve 56, nitrogen gas stream gauge 57 and nitrogen magnetic valve successively.Now, because the gas mixture solenoid electric valve 1311 on the pipeline of deuterium nitrogen mixture gas inlet tube 131 is in opened condition, thus enter in deuterium treatment tank chamber 11 by deuterium nitrogen mixed gas inlet tube 131 by the treated tank top connection 13 of deuterium nitrogen mixed gas that the deuterium introduced by deuterium skirt 2 and the nitrogen introduced by nitrogen skirt 3 are formed, the pressure of deuterium and nitrogen is disclosed by deuterium reducing valve pressure gage 521 and nitrogen reducing valve pressure gage 561 respectively.
Enter into the concentration of deuterium nitrogen mixed gas in deuterium treatment tank 11 and the concentration of deuterium is predicted by the deuterium concentration tester 61 of deuterium concentration detecting mechanism 6, specifically: upper communicating pipe check valve 671 and lower communicating tube check valve 681 be all in closedown and under state that inlet pipe needle-valve 64 and inlet pipe magnetic valve 65 are all in unlatching, deuterium nitrogen mixed gas in deuterium treatment tank chamber 11 is treated tank lower sub 15 successively, tester inlet pipe 62, inlet pipe magnetic valve 65, inlet pipe needle-valve 64 and tester inlet mouth 611 enter deuterium concentration tester 61, the concentration of deuterium is measured by deuterium concentration tester, if the concentration of deuterium is too low, so the open degree of deuterium under meter 53 is strengthened, and the open degree of nitrogen gas stream gauge is reduced simultaneously, vice versa, thus make the concentration of the deuterium in deuterium treatment tank chamber 11 reach processing requirement (being generally 3%).
In addition, deuterium nitrogen mixed gas in deuterium treatment tank chamber 11 enters the tester of deuterium concentration by way of inlet pipe needle-valve 64 before, if the negative pressure pressure in deuterium treatment tank chamber 11 is excessive, so 671,681 gas being introduced vapor pipe 63 by opening upper and lower communicating pipe check valve, draining into the external world (outdoor) by vapor pipe 63.By the observation to treatment tank tensimeter 1321, when after the indicating value such as 685torr that the pressure in deuterium treatment tank chamber 11 reaches required by technique, gas mixture solenoid electric valve 1311 is in closing condition, namely close gas mixture solenoid electric valve 1311, stop introducing deuterium and nitrogen in deuterium treatment tank chamber 11.
To be arranged in deuterium treatment tank chamber 11 and the optical fiber be placed on bearing optical fiber dolly 7 carries out the process of deuterium process, pressure in deuterium treatment tank chamber 11 maintains the scope of 675-685torr, and deuterium concentration is 3%, maintain 24h in this condition, namely optical fiber is done to the deuterium process of 24h.In the treating processes of 24h, if treatment tank tensimeter 1321 shows pressure lower than 675torr, so, implement tonifying Qi by deuterium under meter 53, nitrogen gas stream gauge 57 and gas mixture solenoid electric valve 1311 as aforementioned and grasp deuterium concentration by deuterium concentration tester 61.
When after process 24h, again enable vacuum device 4, carry out second time and vacuumize, the deuterium nitrogen mixed gas in deuterium treatment tank chamber 11 is drained into the external world, is namely discharged by vacuum pump air outlet 422.The Pressure Drop that pending pressure tank table 1321 discloses in deuterium treatment tank chamber 11 opens safety valve 1322 to 100torr, make the pressure in deuterium treatment tank chamber 11 and ambient atmosphere pressure balanced, then open open-close type cover 12, shift out bearing optical fiber dolly 7, the optical fiber completing deuterium process is got from, enter next circulation.
If when using two deuterium treatment tanks 1 resemble shown in Fig. 2 simultaneously, under aforementioned state of being opened by gas mixture solenoid electric valve 1311, so open the transition communicating pipe control valve 91 be positioned on the pipeline of transition communicating pipe 9, to deuterium treatment tank 1 air feed simultaneously on two simultaneously.According to professional general knowledge, two deuterium treatment tanks 1 respectively have corresponding vacuum device 4 and bearing optical fiber dolly 7.
In sum, technical scheme provided by the invention overcomes the shortcoming in prior art, completes invention task, achieves the technique effect referred in the superincumbent technique effect hurdle of applicant objectively.
