At present, the quantitative injector detected applied to oil product has not been reported, the sample introduction for detecting oil product micro-moisture
Pin is generally 1mL syringe sampling pins, and the sample introduction needle does not have quantitative loop, it is impossible to accurate quantitative analysis, has the following disadvantages：
1st, syringe cone core easily drops；
2nd, vision and experience reading need to be leaned on by drawing the volume of oil sample, and for the experimenter lacked experience, reading is often not
It is accurate；
3rd, the parallel oil sample volume drawn twice is difficult to be consistent, and causes the difference of Parallel testing result twice and can not expire
Foot《Transformer oil and steam turbine oil determination of moisture method (coulomb method) GB/T7600-2014 in operation》Precision is wanted
Ask, cause to detect data invalid.
The content of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art to detect that oil product is micro there is provided one kind
The quantitative injector of moisture, can be corrected to fixed volume at any time, simple in construction, easy for installation.
To solve above technical problem, a kind of technical scheme that the utility model is taken is：
It is a kind of detect oil product micro-moisture quantitative injector, including outer syringe, be placed in outer syringe push rod, positioned at outer
The long syringe needle of syringe bottom and the graduation mark for being engraved in outer needle cylinder surface, outer syringe outer sheath are equipped with quantitative cutting ferrule, quantitative cutting ferrule
Including fixed geometrical clamp on the outside of outer syringe, the U-shaped quantitatively bar that is connected mutually is slided up and down with geometrical clamp and for limiting fixation
Folder and the positioner of U-shaped quantitative both bars relative position, the top of push rod are located at below the cross bar of U-shaped quantitative bar, U-shaped quantitative
Graduation mark is carved with the montant of bar.
Preferably, through hole is offered on geometrical clamp, two montants of U-shaped quantitative bar are located in through hole respectively, positioning dress
Put and communicated including being opened in geometrical clamp side with through hole and the circular hole perpendicular with through hole direction, regulation spiral shell is provided with circular hole
It is female.
Preferably, anti-skidding sealing ring is set between geometrical clamp and outer syringe outside.
Due to the use of above technical scheme, the utility model has the following advantages that compared with prior art：
The utility model is equipped with quantitative cutting ferrule in outer syringe outer sheath, and quantitative cutting ferrule includes fixed consolidating on the outside of outer syringe
The U-shaped quantitative bar that clamp and mutually being slided up and down with geometrical clamp is connected, the top of push rod is located at below the cross bar of U-shaped quantitative bar, U-shaped
Graduation mark is carved with the montant of quantitative bar, fixed volume can be corrected at any time, can ensure that each sampling volume is consistent,
Reduce because of the experimental error that sampling volume different band is come, it is simple in construction, it is easy for installation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein：1st, outer syringe；2nd, push rod；3rd, geometrical clamp；4th, U-shaped quantitative bar；5th, adjusting nut；6th, anti-skidding sealing ring.
Embodiment
The utility model is described in further details below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the utility model is a kind of detects the quantitative injector of oil product micro-moisture, including outer syringe 1, puts
In the push rod 2 in outer syringe 1, the long syringe needle positioned at the outer bottom of syringe 1 and the graduation mark for being engraved in the outer surface of syringe 1, long syringe needle
The middle and lower part of microwater device electrolyte can be deep into, it is ensured that the moisture in oil product fully participates in cell reaction, the outer outer sheath of syringe 1
Equipped with quantitative cutting ferrule, quantitative cutting ferrule, which includes fixing in the geometrical clamp 3 in the outer outside of syringe 1, with geometrical clamp 3, mutually slides up and down what is be connected
U-shaped quantitative bar 4 and the positioner for limiting geometrical clamp 3 and U-shaped quantitative both bars 4 relative position, the top of push rod 2 is located at
Below the cross bar of U-shaped quantitative bar 4, graduation mark, scale ascending arrangement from top to bottom are carved with the montant of U-shaped quantitative bar 4.
In the present embodiment, through hole is offered on geometrical clamp 3, two montants of U-shaped quantitative bar 4 are located in through hole respectively
Interior, positioner, which is specifically included, to be opened in the side of geometrical clamp 3 and is communicated with through hole and the circular hole perpendicular with through hole direction, in circular hole
