When the liquid does not need to be diluted, it can flow directly from the normally open end to the common end of the valve 16. The second dilution valve 15 is connected with the common end of the valve of the multi-way valve 16, the normally closed end of the valve of the multi-way valve 16 is connected to the liquid discharge pipe 17, the normally open end of the valve of the multi-way valve 16 is connected to the lower end interface of the flow cell 5, and the upper interface of the flow cell 5 is connected to the common end of the evacuation valve 2.
Principle of operation
In the process of extracting pure water, the valve of the pure water pipe 9 and the valve of the emptying valve 2 are opened, the peristaltic pump 18 rotates to extract pure water from the valve of the pure water pipe 9 to enter the ten-row valve, the pure water flows through the water sample detector 13 from the interface above the ten-row valve, flows into the inlet of the peristaltic pump 18, flows to the first dilution valve 14 and the second dilution valve 15 from the outlet of the peristaltic pump 18, and after passing through the dilution valves, if the valve of the liquid discharge pipe 17 is opened, the liquid is directly discharged from the valve of the liquid discharge pipe 17, so that the ten-row valve and the waterway part are cleaned; if the valve of the drain pipe 17 is not opened, the normally open end of the valve of the multi-way valve 16 flows to the flow cell 5, and when the flow cell 5 is full, the normally open end flows to the common end of the drain valve 2 from above the flow cell 5, and then flows to the waste pipe 3 from the common end of the drain valve 2 for draining.
In the sampling process, the peristaltic pump 18 rotates to draw a sample from the sample tube 7, flows to the peristaltic pump 18 through ten rows of valves, flows to the first dilution valve 14 and the second dilution valve 15 from the peristaltic pump 18, determines whether dilution is required by the first dilution valve 14 and the second dilution valve 15, opens the valves of the first dilution valve 14 and the second dilution valve 15 when dilution is required, stores the sample in a normally closed end, flows to the flow cell 5 directly without dilution, flows to the waste discharge tube 3 from an outlet above the flow cell 5 after flowing to the flow cell 5, and flows out of the waste discharge tube 3. The liquid to be diluted is stored in the normally closed end between the first dilution valve 14 and the second dilution valve 15, pure water is pumped from the normally open ends of the first dilution valve 14 and the second dilution valve 15 to the common end of the multi-way valve 16, and the redundant liquid is discharged from the normally closed end liquid discharge pipe 17 of the multi-way valve 16 to the liquid discharge pipe 17 to be a non-toxic liquid discharge pipe.
The process of extracting the agent is consistent with the process of extracting the sample (without dilution). The mixing process is to close all valves to form a loop in the waterway, and the liquid flows and mixes in the loop. The loop is as follows: the port above the flow cell flows to the common port of the valve of the evacuation valve 2, the common port of the valve of the evacuation valve 2 flows to the common port below the ten rows of valves, then flows out of the common port above the ten rows of valves, flows to the inlet of the peristaltic pump 18, flows from the outlet of the peristaltic pump 18 to the common port of the valve of the first dilution valve 14, flows to the valve of the multi-way valve 16 after flowing through the valves of the first dilution valve 14 and the second dilution valve 15, and flows to the port below the flow cell 5 from the common port of the valve of the multi-way valve 16, thus completing the whole loop mixing.
