Water quality analyzer with function of accurately adding reagents into water sample

Abstract

The invention discloses a water quality analyzer with a water sample reagent adding precision function, which can realize the water sample reagent adding precision function of the water quality analyzer through the cooperative use of a storage test tube, a U-shaped tube and a sample adding guide tube. A method comprises steps: a water sample is injected into the storage test tube, the volume of the injected water sample is observed through first scales, after water sample injection work is finished, the storage test tube is sealed through a first sealing plate, a reagent is injected into the sample adding guide tube, and the volume of the injected reagent is observed through second scales; a second piston, a connecting seat and a baffle plate are matched for use, so that the detection efficiency of the water quality analyzer can be effectively improved; an upper top plate is pressed downwards, so that a second sliding pipe moves downwards, and the ends, away from the connecting seat, of the three baffles rotate upwards through a first connecting ring and a rotating shaft; according to the invention, the problems that a water sample reagent adding precision function of the water quality analyzer cannot be realized and the detection efficiency of the water quality analyzer is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of water quality analysis, in particular to a water quality analyzer with the precise function of adding reagents to water samples. Background technique [0002] Human beings cannot live without water, and the quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, not only between countries, but also between different regions of the same country, Th...

Problems solved by technology

[0005] The problem to be solved in one aspect disclosed by the present invention is: how to solve the inability to realize the precise function of water sample adding reagents of the water quality analyzer; Precise function of sample adding reagents; inject the water sample into the storage test tube, observe the volume of the injected water sample through the first scale bar, after the water sample injection work is completed, seal the storage test tube through the first sealing plate, and inject the reagent into the In the sample adding conduit, observe the volume of the injected reagent through the second scale bar. After the reagent injection is completed, seal the sample adding conduit through the second sealing plate; The first connecting ring and the rotating shaft make the end of the three sets of baffles away from the connecting seat rotate downwards, and the end of the three sets of baffles close to the connecting seat turns upwards, so that there is a gap between the connecting seat and the second piston; open the regulating valve, so that A passage is formed between the sampling conduit and the storage test tube, and the regulating valve plays the role of isolation. The handle is pressed down, and the first piston is driven down through the third slide tube, and the pressure generated makes the reagent in the sampling conduit pass through the U-shaped tube. It enters the storage test tube and falls into the water sample through the gap between the connecting seat and the second piston, which can accurately and quickly mix the reagent and water sample, which solves the problem that the water quality analyzer cannot be added in the existing solution. Reagent precision function;
