A kind of application method of high-precision regulation titration outfit, comprising the following steps:
Step 1:
Beaker is placed on eccentric turntable, screw rod is rotated, beaker is fixed on eccentric turntable by two arc fixed blocks
Upper middle position, to beaker and glass burette inside instill experiment liquid；
Step 2:
Turning handle is rotated, is rotated by governor gear group band nutating gear, glass piston is opened, so that in glass burette
The experimental liquid in portion is flowed out by outlet tube,
Because rate of titration, which is opened size by glass piston, to be influenced, for the aperture of more accurate control glass piston,

8. a kind of application method of high-precision regulation titration outfit according to claim 1, which is characterized in that including following
Step:
Step 1:
Beaker is placed on eccentric turntable (7), rotates screw rod (7b), is fixed on beaker by two arc fixed blocks (7b2)
Middle position on eccentric turntable (7) instills experiment liquid to beaker and glass burette (3) are internal；
Step 2:
It rotates turning handle (5b), is rotated by governor gear group (5d) band nutating gear (3b2), open glass piston (3b), make
Glass burette (3) internal experimental liquid is obtained to flow out by outlet tube (3a),
Because rate of titration, which is opened size by glass piston (3b), to be influenced, for opening for more accurate control glass piston (3b)
Degree can will lift operation panel (5e1), so that mandril (5e) is detached from limiting slot (5c1), then push and pull turning handle (5b), selection speed regulation
Some gear on gear set (5d) engages connection with transmission gear (3b2), each tooth for including due to governor gear group (5d)
Tooth number is uniformly distributed identical, therefore different gears is selected to engage with transmission gear (3b2), and turning handle (5b) rotates a circle glass piston
The aperture of (3b) is also different, and being precisely controlled for rate of titration may be implemented in this way；
Step 3:
When rate of titration is slower, the liquid that outlet tube (3a) oozes is easily sticked to the exit outlet tube (3a) and is not easy to fall,
At this moment air pump (8) are opened, air-flow is blown into air blowing chamber (6c) inside by annular air channel (6d) and gas outlet (6d1), logical
Over-blowing air cavity (6c) top curve end face guiding, air-flow are blown downwards along outlet tube (3a) outer wall vertical, by titration liquid from out
It blows off liquid pipe (3a) outlet；
Step 4:
It opens water pump (9a), water flow enters water channel (6e) inside by water inlet pipe (9b), water inlet (6e1), due to water channel
After (6e) scrapes the arc end (6e3) of one end of sap cavity (6b) axis backwards and to scrape sap cavity (6b) inner wall tangent, therefore water flow is gone out
Arcuately end (6e3) enters scrape the inside sap cavity (6b) after spiral edge scrape sap cavity (6b) inner wall and flow downward, sap cavity will be scraped
Titration liquid on (6b) inner wall enters inside beaker from the outflow of lower liquid mouth (6a)；
Step 5:
Start decelerating motor (10), decelerating motor (10) drives eccentric turntable (7) to rotate by eccentric shaft (10a), due to bias
Axis (10a) axis is not arranged on the same straight line with eccentric turntable (7) axis, therefore the eccentric drive beaker of eccentric turntable (7) is eccentric
Rotation, shakes manually instead of operator.
