Background technology
Acid buret is a kind of surveying instrument of titrimetry indispensability, just the concentration of measured matter and concrete content very accurately can be calculated, acid buret adularescent and brown two kinds by the consumption of the standard solution shown by known concentration of standard solution and buret.
Existing acid buret filling liquid is all enter from the top of body is filling, because acid buret pipe diameter is little, filling liquid is inconvenient especially; It is all release unnecessary liquid from cock that existing acid buret returns to zero before titration, operates particularly troublesome; Existing acid buret, the scale mark of buret is too sparse, and thus when being many times between two scale marks when liquid level, its concrete decimal place must judge by naked eyes completely, easily occurs error; Existing acid buret; the fixed form of cock and cock inner room mainly contains cock to be tied up with bungee and fixes on cock is overlapped or by the mode of bolt and nut; but; bungee is not easy tighten; solution often can ooze out from cock surface; and rubber warp is because often contact with acids solution or oxidizing solution; easily aging; need often to change, with bolt and nut, the top of cock body arranges screw thread; with nut, cock is fixed in cock cover; need when titration operation frequently to rotate cock, cause nut loosening, solution easily oozes out from cock surface.
Therefore, be necessary to improve existing acid buret, make acid buret structurally more perfect, measurement result is more accurate, meets the needs of operator.
Summary of the invention
In order to overcome Problems existing in background technology, the utility model provides a kind of acid buret, can fill with add liquid from storage spheroid, easy to operate; Energy automatic zero set (AZS), saves solution, accurately can read consumed titer volume, reduces error; Leakage can be prevented.
For achieving the above object, the utility model is implemented by following technical scheme:
A kind of acid buret, comprise body, stopper, water dropper, described body is carved with scale, the top of body is provided with storage spheroid, with the zero graduation line side pipe that is interlinked to the outside in being provided with of level place mutually on the sidewall of body, and communicated with container by pipeline, a slip cap be made up of transparent material described body is equipped with, magnifier is equipped with in the center in slip cap front, the slip cap back side relative with magnifier indicates fine scale line and liquid level position line, described stopper comprises cock cover and cock, described cock comprises cock body and handle, cock body is arranged porose, cock cover is exposed in hole, the inwall in hole is provided with internal thread, bar portion is provided with in hole, the outer wall in bar portion is provided with external thread.
Further, described side pipe angle that is downward and body is 45 °.
Further, the zero graduation line level mutually of described side pipe and bore minimum point in body connection and scale.
Further, described cock body is provided with pad, pad is between hole and cock are overlapped.
The beneficial effects of the utility model:
1. the opening owing to storing up spheroid is comparatively large, thus easy filling solution.
2. liquid feeding completed continuously with zeroing moment, improve work efficiency, can save a large amount of standard solution.
3. owing to being provided with the slip cap for accurately reading liquid level scale on acid buret, can judge liquid level position quickly and easily, and more accurately can determine and read liquid level scale.
4. being threaded by bar portion and hole, is closely fixed on cock in cock cover, after cock body arranges pad, can prevents the seepage of solution further.

Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to facilitate the technical staff to understand.
As Figure 1-4, a kind of acid buret, comprises body 1, stopper 2, water dropper 3, and described body 1 is carved with scale 4, and the top of body 1 is provided with storage spheroid 5, and the opening of storage spheroid 5 is comparatively large, thus easy filling solution when using.
With the zero graduation line side pipe 6 that is interlinked to the outside in being provided with of level place mutually on the sidewall of body 1, and communicated with container 8 by pipeline 7, described side pipe 6 angle that is downward and body 1 is 45 °, the zero graduation line level mutually of described side pipe 6 and bore minimum point in body 1 connection and scale, liquid feeding can be made automatically to complete continuously with zeroing moment, improve work efficiency, save a large amount of titers.
A slip cap be made up of transparent material 9 body 1 is equipped with, magnifier 10 is equipped with in the center in slip cap 9 front, slip cap 9 back side relative with magnifier 10 indicates fine scale line 11 and liquid level position line 12, owing to being provided with the slip cap 9 for accurately reading liquid level scale mark on acid buret, can judge liquid level position quickly and easily, and more accurately can determine and read liquid level scale.
Described stopper 2 comprises cock cover 13 and cock 14, and cock 14 comprises cock body 15 and handle 16, and cock body 15 arranges porose 17, and cock cover 13 is exposed in hole 17, and the inwall in hole 17 is provided with internal thread, is provided with bar portion 18 in hole 17, and the outer wall in bar portion 18 is provided with external thread.Described cock body 15 is provided with pad 19, and pad 19 overlaps between 13 in hole 17 and cock, by being threaded of bar portion 18 and hole 17, cock 14 being closely fixed in cock cover 13, after cock body 15 being arranged pad 19, can preventing the seepage of solution further.
The course of work of the present utility model: before the titration of use acid buret, leakage detection to be carried out to acid buret, cut-out tap 14, near dress water to " 0 " scale, uprightly about two minutes, examine and drip with or without water droplet, then cock 14 is rotated 180 °, more upright two minutes, examine and drip with or without water droplet, to leak as found that there is or cock 14 rotates inflexible phenomenon, then need to take off cock 14 recoat vaseline.If water-tight, cock 14 rotates more flexible, then use standard solution rinse acid buret three times, after rinse completes, fill with from storage spheroid 5 and add solution, bubble-free in acid buret after flushing with zero graduation line, start titration, left hand rotates cock 14, the right hand is jiggled and has been dripped the measured matter of indicator in conical flask, the color change of eye observation measured matter, rate of addition is from fast to slow, stop dripping after the change of measured matter color, if nondiscolouring in measured matter 30s, then illustrate and arrived titration end-point, stop a moment, the scale mark of mobile slip cap 9 to liquid, accurate reading scale, titration completes, cleaning acid buret, reversal of the natural order of things is on burette holder.
