Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring instruments, in particular to a water sample switching device of an online water quality monitoring instrument. Background Art

[0002] The water sample switching device of the online water quality monitoring instrument is an important part for realizing automatic and continuous monitoring of water quality parameters. At present, the existing online water quality detection instruments on the market can only be used for testing one water sample. However, in the actual operation of the water plant, it is often necessary to simultaneously monitor the water quality of multiple indicators extracted from multiple locations online, such as source water, process water and factory water. This requires the installation of multiple online monitoring devices, which greatly increases the cost and occupies a large amount of site space. It is difficult to install and maintain, and is time-consuming and labor-intensive.

[0003] The announcement number CN209280699U discloses a water sample switching device for an online water quality monitoring instrument, comprising: a box body for accommodating various components; a solenoid valve group arranged in series through a liquid pipeline, comprising a first solenoid valve, a second solenoid valve, a third solenoid valve, and a fourth solenoid valve, any of which is normally open when in operation; a number of straight-through valves corresponding one-to-one to the solenoid valves, for accommodating various types of water samples to be tested; a circuit control system; a liquid pipeline; the solenoid valve group, the straight-through valve, the circuit control system, and the liquid pipeline are arranged inside the box body, the solenoid valve is connected to the corresponding straight-through valve, and the solenoid valve group is electrically connected to the circuit control system. The water sample switching device for an online water quality monitoring instrument of the utility model, based on the technical feature of simultaneously arranging multiple solenoid valves, detects water samples of different water qualities by switching the open and closed working states of each solenoid valve, thereby achieving the goal of using a single device to detect multiple water samples.

[0004] This patent uses multiple solenoid valves to achieve the goal of using a single device to detect multiple water samples. However, different water samples have different compositions. If the residual water samples are not cleaned in time after detection, they will affect the accuracy of other water sample detection. However, this patent does not have a corresponding cleaning device, which results in residual water samples after each detection, affecting the accuracy of the next detection.

[0005] Based on this, a water sample switching device for an online water quality monitoring instrument is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
