Abstract
The utility model discloses a quantitative sampling device, which comprises a dosing cup and a solenoid valve, wherein the dosing cup includes a cup body, a sample inlet, a sample outlet and an overflow port, and the sample inlet is connected with the solenoid valve interface through a hose. Due to the arrangement of the overflow port, the dosing cup can further determine the amount of the sample in the dosing cup through overflowing. Accordingly, the quantitative sampling device can improve the sampling accuracy and solve the problem of poor sampling accuracy of a peristaltic pump. Since the dosing cup is usually made of non-deformable materials, the quantitative sampling device can be used repeatedly without being influenced by the duration of service. In addition, the quantitative sampling device has the advantages of simple structure and easy maintenance, and greatly reduces the use cost.
Description
Technical field
The utility model relates to a kind of quantitative sampling device, specifically, relates to a kind of quantitative sampling device that is used for on-line automatic titrator.
Background technology
Existing on-line automatic titrator is directly sample to be added in the measuring cup by peristaltic pump, because there is the timing sampling poor repeatability in peristaltic pump, and service time is long more, poorer and working time of its accuracy and repeatability is long also can to make defective such as pump line distortion, so there is the problem of sampling poor accuracy in above-mentioned on-line automatic titrator.At present, for guarantee the accuracy of on-line automatic titrator sampling as far as possible, the method for pump line is constantly changed in general employing, and this has not only increased the maintenance workload of on-line automatic titrator, has also increased use cost, has reduced the service life of on-line automatic titrator.Therefore, market in urgent need solves the sampling accuracy problem of on-line automatic titrator.
The utility model content
The purpose of this utility model is to be to provide a kind of quantitative sampling device, has the problem of the poor accuracy of taking a sample and satisfies the demand in market to solve 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 quantitative sampling device that the utility model provides comprises Measuring glass and magnetic valve, and described Measuring glass comprises cup, injection port, outlet and overfall, is connected by flexible pipe between outlet wherein and solenoid valve interface.
The injection port of described Measuring glass and outlet are located at the bottom of cup, and overfall is located at the top of cup.
Described magnetic valve is the electromagnetic clamp pipe valve, and the coupled flexible pipe of the outlet of Measuring glass is a rubber hose.
Compared with prior art, the beneficial effects of the utility model are as follows:
1) because Measuring glass of the present utility model is provided with overfall, can be by overflow, thereby improved the accuracy of sampling to the sample second metering in the Measuring glass, solved the problem that there is poor accuracy in the peristaltic pump sampling.
2) make by on-deformable material owing to Measuring glass is many, thereby can make quantitative repeatability not be subjected to the influence of length service time.
3) the utility model is simple in structure, safeguards easily, greatly reduces use cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. Measuring glass; 1-1. cup; 1-2. injection port; 1-3. outlet; 1-4. overfall; 2. magnetic valve; 2-1. solenoid valve interface; 3. flexible pipe.
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 quantitative sampling device that the utility model provides, comprise Measuring glass 1 and magnetic valve 2, described Measuring glass 1 comprises cup 1-1, injection port 1-2, outlet 1-3 and overfall 1-4, injection port 1-2 wherein and outlet 1-3 are located at the bottom of cup 1-1, and overfall 1-4 is located at the top of cup 1-1; Described magnetic valve 2 is the electromagnetic clamp pipe valve, is connected by rubber hose 3 between the outlet 1-3 of Measuring glass 1 and solenoid valve interface 2-1.
When on-line automatic titration, sample is not directly to enter to participate in titration in the measuring cup, but at first enter in the Measuring glass, overfall by Measuring glass falls unnecessary sample overflow, to play further quantitative effect, then sample is added to and carries out titration in the measuring cup, so the utility model improves the sampling accuracy of on-line automatic titrator, solved the existing in prior technology defective.
