Description
Technical field
The utility model relates to a kind of liquid samplers.
Background technique
Liquid sampling is the most common operation in Chemical Manufacture, it is often necessary to be sampled analysis, mesh to different liquid
Preceding sampling mode the most easy is sampled by pipettor, and pipettor is generally glass tube, directly by liquid relief when sampling
Device is inserted into canned or barreled liquid, after liquid enters in pipettor, is blocked the upper port of pipettor with finger, by liquid relief
Device is removed from liquid, and due to the difference of the inside and outside atmospheric pressure of pipettor, some sample liquids can be stored in pipettor,
It finally unclamps finger the liquid being stored in pipettor is fitted into sample bottle.But if hand during above-mentioned sampling
Refer to upper port is pressed it is poorly sealed, in pipette sample liquids will it is easy to appear unrestrained problems, and due to pipettor
During being inserted into liquid, what the inlet opening of pipettor was always on, the inlet opening of pipettor reaches destination layer position
The liquid for unavoidably having layer position shallower in the process enters in pipettor in advance, this can reduce the precision of sample liquids, and then to behaviour
The sampling result analysis for making personnel causes to judge by accident.
Utility model content
The purpose of this utility model is to provide a kind of liquid samplers, for solving in the prior art to different depth
When destination layer position liquid is sampled, there are the lower technical problems of sampling precision.
To achieve the above object, the technical solution of the utility model liquid sampler is:

In there is the problem of uplink due to the pressure action by liquid.
Further, the lower end for taking fluid cylinder, which is provided with, is adapted and for the tapered of cone insertion with the cone
The slot bottom position of tapered slot is arranged in slot, the inlet opening.Sealing contact surface is increased, leakproofness is improved.
Further, the closeouts releasable connection is in the lower end of center-pole.So that liquid sampler convenient disassembly, favorably
In the maintenance of liquid sampler.
Further, the upper end for taking fluid cylinder is provided with upper end cover, is provided on the upper end cover and passes through for center-pole
Pilot hole.So that center-pole has preferable guiding performance.
Further, the return springs are the reset spring being set in section of stretching out, are set in the upper section of stretching out
It is equipped with the Stop structure for being pressed on reset spring on the upper end cover.So that integral arrangement mode is fairly simple.
Further, the upper end of the upper section of stretching out is provided with handle, and the handle constitutes the Stop structure.Handle
Setting facilitate the pushing to center-pole.
Further, it is provided on the side wall for taking fluid cylinder for observing the scale value for taking fluid cylinder decentralization depth.So that
Taking the decentralization depth of fluid cylinder can be presented in face of operator in time and intuitively, meet the liquid to different target layer position
Sampling demand.
