Description

Technical Field

[0001] This utility model belongs to the technical field of detection and sampling devices, and specifically relates to a metrological detection and sampling device. Background Technology

[0002] Unknown liquids require testing before use to ensure safe handling. Currently, liquid testing often involves using a sampler to extract the liquid and then sending it into testing equipment. However, when testing liquids, a single reaction solution often cannot determine the liquid type, requiring multiple reaction solutions to be tested simultaneously. However, different reaction solutions require different quantities of liquid, and it is impossible to accurately measure the amount of liquid poured from different samplers when adding liquid to the reaction solution. Furthermore, the unknown liquid is exposed, posing a safety risk. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a measurement and sampling device.

[0004] This utility model is achieved through the following technical solution: A metrological sampling device includes several reagent tubes, characterized in that: the surface of the reagent tubes is provided with scale lines, the bottom of the reagent tubes is connected to an output hose, the top of the output hose is provided with an output valve, a tube plug is installed on the top of the reagent tubes, the tube plug is connected to an input hose, the bottom of the input hose is provided with an input valve, the end of the input hose is provided with an input threaded connector, and the end of the output hose is provided with an output threaded connector.

[0005] The upper part of the reagent tube is integrally provided with a retaining ring, the reagent tube is inserted into the support arm, the support arm is fixed on the rotating shaft, and the rotating shaft is installed on the base.

[0006] An airbag is connected to the output hose.

[0007] The beneficial effects of this utility model are: the liquid is sent into the reagent tube through the threaded connector, and the liquid is also sent from the reagent tube into the reaction liquid through the threaded connector, thus avoiding the liquid being exposed throughout the process. The measurement is accurate when inputting liquid from the reagent tube into the reaction liquid, and the liquid in the reagent tube can be sent into different reaction liquids. While ensuring safety, it makes sampling, measurement and detection faster and more accurate. Attached Figure Description

[0008] The present invention will be further described below with reference to the accompanying drawings.

[0009] Appendix Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram, 1 is the reagent tube, 2 is the graduation line, 3 is the output hose, 4 is the output valve, 5 is the tube plug, 6 is the input hose, 7 is the input valve, 8 is the input threaded connector, 9 is the output threaded connector, 10 is the retaining ring, 11 is the support arm, 12 is the rotating shaft, 13 is the base, and 14 is the airbag. Detailed Implementation

[0010] The attached figure shows a specific embodiment of this utility model. This embodiment includes several reagent tubes 1, with scale lines 2 on the surface of the reagent tubes 1, an output hose 3 connected to the bottom of the reagent tubes 1, an output valve 4 at the top of the output hose 3, a tube plug 5 installed at the top of the reagent tubes 1, the tube plug 5 connected to an input hose 6, an input valve 7 at the bottom of the input hose 6, an input threaded connector 8 at the end of the input hose 6, and an output threaded connector 9 at the end of the output hose 3.

[0011] The upper part of the reagent tube 1 is integrally provided with a retaining ring 10. The reagent tube 1 is inserted into the support arm 11, and the support arm 11 is fixed on the rotating shaft 12. The rotating shaft 12 is installed on the base 13. The output hose 3 is connected to the air bag 14.

[0012] Using the metering and sampling device of this invention, connect the input threaded connector 8 to the connector of the original liquid storage tank, open the input valve 7, pour the liquid into the reagent tube 1, close the input valve 7, and disconnect the input threaded connector 8. Connect the output threaded connector 9 to the connector of the reaction tank storing the reaction solution, open the output valve 4, and the liquid in the reagent tube 1 can enter the reaction tank. While the liquid is outputting, the output volume can be determined at any time by the scale line 2. When the required volume is reached, close the output valve 4. To make the liquid volume entering the reaction solution more accurate, squeeze the air bag 14 to allow all the residual liquid to enter the reaction solution. Insert the reagent tube 1 into the hole of the support arm 11, and lock the retaining ring 10 on the support arm 11, so that the reagent tube 1 is suspended at a high point, which facilitates the smooth entry of liquid into the reaction solution. When there are multiple reaction solutions, if the liquid volume in one reagent tube 1 is insufficient, the rotating shaft 12 can be rotated to make the empty reagent bottle 1 face outward and the reagent bottle 1 with liquid inward, so that the liquid in the reagent bottle 1 can be sent into the reaction solution.
