Abstract
The utility model discloses a high-precision measuring cup structure comprising a cup body, a sample inlet, a sample outlet and an overflow port, wherein, the cup body comprises an upper cup body and a lower cup body; and the diameter of the upper cup body is smaller than that of the lower cup body. Compared with the prior art, the cup body of a measuring cup is set into a shape with thin top and thick bottom, so that the problem that the precision of an internal fluid level of an original vertical-barrel-type cup body is hard to control can be solved, the sampling precision can reach 0.2 percent, and the high-precision sampling requirement of an on-line autotitrator can be satisfied completely. In addition, the high-precision measuring cup structure also has the beneficial effects of simple structure, easy manufacture, low use cost, etc.
Description
Technical field
The utility model relates to a kind of Measuring glass structure, specifically, relates to a kind of high-precision fixed measuring cup structure that is used for on-line automatic titrator.
Background technology
The sampling mode of on-line automatic titrator has: 1) directly sample is added in the measuring cup by peristaltic pump; 2) at first sample is added in the Measuring glass by peristaltic pump, add in the measuring cup again after quantitatively by Measuring glass.Because there is the timing sampling poor repeatability in peristaltic pump, and exist service time long more, poorer and working time of its accuracy and repeatability is long also can to make defective such as pump line distortion, therefore directly sample is added the problem of the sampling mode existence sampling poor accuracy of measuring cup by peristaltic pump, be difficult to satisfy the titrimetric requirement of high accuracy.At present, on-line automatic titrator adopts the quantitative sampling device that Measuring glass is set for can satisfy the sampling precision requirement.Existing Measuring glass structure is a straight barrel type list cup, and cup is provided with injection port, outlet and overfall, and there is the problem of level control difficulty in this straight barrel type structure, because liquid level is slightly mutually weaker up and down, all can cause very mistake.Therefore, existing on-line automatic titrator still exists sampling precision not high, can not satisfy the problem of high accuracy titrimetry requirement, a kind of high-precision fixed measuring cup of market in urgent need.
The utility model content
The purpose of this utility model is to be to provide a kind of high-precision fixed measuring cup structure, to solve the high-accuracy sampling requirement of on-line automatic titrator.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
The high-precision fixed measuring cup structure that the utility model provides comprises cup, injection port, outlet and overfall, and it is characterized in that: described cup is made up of last cup and lower cup body, and the diameter of last cup is less than the diameter of lower cup body.
Described injection port and overfall are located on the cup, and outlet is located at the bottom of lower cup body.
The described cup of going up is provided with dashpot.
Compared with prior art, the utility model is made as up-thin-low-thick shape by the cup with Measuring glass, solve the problem that the interior liquid level of original straight barrel type cup is difficult to control accuracy, made sampling precision can reach 2/1000ths, can satisfy the high-accuracy sampling requirement of on-line automatic titrator fully.In addition, the utility model also has simple in structure, handling ease, the low beneficial effect that waits of use cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. cup; 1-1. last cup; 1-2. lower cup body; 2. injection port; 3. outlet; 4. overfall; 5. dashpot.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed, complete explanation:
Embodiment
As shown in Figure 1: the high-precision fixed measuring cup structure that the utility model provides, comprise cup 1, injection port 2, outlet 3 and overfall 4, described cup 1 is made up of last cup 1-1 and lower cup body 1-2, and the diameter of last cup 1-1 is less than the diameter of lower cup body 1-2; Described injection port 2 and overfall 4 are located on the cup 1-1, and outlet 3 is located at the bottom of lower cup body 1-2, and upward cup 1-1 is provided with dashpot 5.
After sample was added in the cup 1 by injection port 2, unnecessary sample can fall by overfall 4 overflows, to play further quantitative effect.Because cup of the present utility model is up-thin-low-thick shape, overfall is located on the thin last cup of diameter, more little according to diameter, highly to more little this principle of capacity impact of volume, therefore, Measuring glass structure of the present utility model can make sampling precision reach 2/1000ths, can satisfy the high-accuracy sampling requirement of on-line automatic titrator fully.
Claims (3)
