Abstract

The invention aims at providing a liquid path system based on unit metering and a use method thereof. The liquid path system has the functions of fetching liquid, mixing and discharging the liquid at the same time, guarantees accurate metering and is convenient to use. In order to achieve the effects, the liquid path system comprises an upper solenoid valve, a reaction container, a lower solenoid valve, a liquid level sensor, a multi-position valve, a three-way valve and a peristaltic pump. Through the structure, the liquid path system has the following benefits as follows: a volume metering mode of an extraction unit is achieved through a hard plastic guide pipe connected between a public hole of the multi-position valve and the liquid level sensor; the whole liquid path system only makes use of one liquid level sensor; and a reagent is metered and directly enter the reaction container to be subjected to processes of mixing, reacting, testing and the like.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a liquid circuit system based on unit metering and a using method thereof. Background technique [0002] Water is the source of life and an important material basis for the realization of economic and social sustainable development strategies. Water quality monitoring is an important basis for water resources management and protection, and it is an urgent need for continuous deepening of environmental protection and continuous strengthening of supervision. The core of water quality monitoring is to use water quality analyzers to monitor water quality online. [0003] In fluid analysis, the design of the hydraulic system is extremely important, which directly affects the sensitivity of the method and the accuracy of the analysis results. For water quality analyzers, the liquid circuit system must have the functions of accurately extracting reagents, being resistant to strong...
