For, air inlet port is different with the position of air outlet, and vacuumizing effect and note hydrogen effect are more preferable.Reaction kettle 1, which is used to place, to be needed
The optical fiber of hydrogen is carried, hydrogen purge pipe 7 is provided with reaction kettle 1, hydrogen purge pipe 7 is arranged on kettle cover 11；Pneumatic vacuum pump 2
After carrying out vacuumize process to reaction kettle 1, pneumatic hydrogen pressurization pump 3 is completed to carry hydrogen process in high pressure hydrogen injection reaction kettle 1
Hydrogen is discharged by the hydrogen purge pipe 7 afterwards.
Pneumatic vacuum pump 2 and pneumatic hydrogen pressurization pump 3 are to produce a kind of new, efficient, clear of negative pressure using positive pressure source of the gas
Clean, economic, small-sized vacuum component, this cause the place for having compressed air or in a pneumatic system at the same needs just
The place of negative pressure, which obtains negative pressure, to be become very easily and conveniently, it is often more important that during vacuumizing or injecting hydrogen,
Using gas-powered, no electric arc and spark, are entirely used for the place of inflammable, explosive liquid or gas, safe operation.Reaction
The top of kettle 1 is additionally provided with the safety valve 8 for preventing hypertonia in reaction kettle 1, when the pressure value in reaction kettle 1 exceedes peace
The value set in full valve 8, the meeting releasing pressure automatically of safety valve 8, prevents the danger produced due to hypertonia.

As shown in Fig. 2, Fig. 2 is the flow diagram that a kind of optical fiber of the utility model carries hydrogen methods.A kind of optical fiber carries hydrogen side
Method, specifically includes following steps：
1. the kettle cover 11 of a reaction kettle 1 is opened, it would be desirable to which the optical fiber for carrying hydrogen is placed in reaction kettle 1, then by kettle cover 11
Tightened with nuts and bolt.
2. vacuumize process is carried out to reaction kettle 1 using pneumatic vacuum pump 2, until vacuum is less than -0.09MPa.When up to
The first valve 23 is closed after to desired vacuum, then pneumatic vacuum pump 2 is closed, by vacuum meter 6 come observing response kettle 1
Interior vacuum.Amount of oxygen at this time in reaction kettle 1 is extremely low, then by hydrogen injection reaction kettle 1, since hydrogen accounting is much big
In the explosion limit scope of hydrogen, security risk is greatly reduced.Vacuum values requirement is less than -0.09MPa.The explosion of hydrogen
The limit is 4%-74.2%, this is and air mixture ratio, that is, when hydrogen containing 4%-74.2% in air, is met bright
Fire explodes.When vacuum is less than -0.09MPa, air is only original 10% in reaction kettle, and when injecting hydrogen, reaction kettle is
More than 1Mpa is can reach, hydrogen accounting in reaction kettle is 99% at this time, much exceedes the scope of 4%-74.2% greatly.When being added to
More than 10MPa, hydrogen accounting in reaction kettle is 99.9%.
3. pair reaction kettle 1 closes 6 valve of vacuum meter before injecting air, 5 valve of pressure gauge is opened, and is increased by pneumatic hydrogen
Press pump 3 injects high pressure hydrogen in reaction kettle 1, until pressure value reaches 10-12MPa.When reaching required pressure value, close anti-
The air intake valve of kettle 1 is answered, pneumatic hydrogen pressurization pump 3 is closed, closes the 3rd valve 34.Pressure value is 10-12MPa.With load hydrogen
The increase of pressure, standard single-mode fiber light sensitivity are bigger.But for producing fiber grating, if carrying the too conference of hydrogen pressure causes to make
Fiber grating cost is excessive, while carries hydrogen pressure and increase so that carrying hydrogen operation process increase danger.Based on selection low cost and
Mode easy to operate, so selection 10-12MPa is load hydrogen pressure value.
4. reaction kettle 1 keeps high pressure to place 10-20 days, carry out carrying hydrogen processing；Preferably, reaction kettle 1 keeps high pressure to place
14 days.Many experiments prove that the effect for carrying 14 days hydrogen time is best：Place the fiber in reaction kettle 1 and carried by different time
Hydrogen, carry hydrogen time when being respectively 72 small, 120 it is small when, 168 it is small when, 336 it is small when, 480 it is small when, 648 it is small when, from figure 3, it can be seen that
The concentration of hydrogen tends to saturation in optical fiber at about 14 days, then lengthens load hydrogen and the concentration of hydrogen in optical fiber is not also increased significantly
Add.Therefore, it can most be taken into account when carrying 14 days hydrogen time and carry hydrogen effect and cost.
5. completing optical fiber carries hydrogen process, the second valve 13 on hydrogen purge pipe 7 is then gently twisted, hydrogen is discharged, etc.
When pressure in reaction kettle 1 is equal with atmospheric pressure, you can kettle cover 11 is opened, takes out optical fiber.
The utility model single can carry out 2 myriametre optical fiber carrying hydrogen processing, and it is extremely low that ultrahigh in efficiency and optical fiber carry hydrogen cost, from
And saving fund reduces the cost of fiber grating.On the other hand, different valves is respectively adopted to be vacuumized, inject hydrogen
With discharge hydrogen, vacuumize process is carried out to the air of reaction kettle 1 before load hydrogen every time, ensure that the vacuum before injection hydrogen
Degree, ensure that the effect vacuumized, it is ensured that carry the security of hydrogen operation.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent replacement, improvement and so on, should be included in the guarantor of the utility model
Within the scope of shield.
