Description

Technical Field

[0001] This utility model relates to the field of pH rotary valve technology, and in particular to an innovative pH rotary valve system. Background Technology

[0002] Currently, some instruments use pH electrodes in series with multiple rotary valves, which significantly increases costs. Furthermore, when using multiple selector valves to achieve these functions, more tubing is needed to connect the different valves, increasing the external volume of the tubing. In addition, the selector valves must follow a certain arrangement pattern, which is generally controlled by software and is difficult to change once determined. When switching rotary valves, the software must control the rotors of multiple column selector valves to rotate simultaneously, so that each column selector slot connects to the corresponding selector hole almost simultaneously. This process has high requirements for synchronization and accuracy, making the software program more complex and less tolerant of errors.

[0003] Therefore, we propose an innovative PH rotary valve system. Utility Model Content
