TECHNICAL FIELD
[0001] The utility model relates to the field of pH electrode, especially a flow cell for installing pH electrode. BACKGROUND
[0002] At present, in the continuous production process of food, medical treatment, metallurgy, chemical industry and the like, the requirement of detecting the pH value in fluid medium is more and more, and the reliability and accuracy of pH value detection are also higher and higher. The sample measured by the on-line pH analyzer can truly and accurately reflect the pH value of the fluid medium, and is convenient for the maintenance personnel to calibrate and maintain it regularly, so the installation mode of the pH electrode is particularly important. The installation mode of the electrode of the on-line pH analyzer can generally adopt the sinking installation or the flow cell installation. If the container is flammable and explosive, toxic and harmful, and strong corrosive medium, then the sinking installation is not suitable, and the flow cell installation is adopted. The usual method is to set a sampling pipe, install the flow cell on the sampling pipe, and then install the electrode on the flow cell.
[0003] The traditional flow cell is directly installed on the sampling pipe, and the electrode is installed on the base and inserted into the sampling pipe, but when the electrode of different sizes is replaced, the base needs to be welded and modified on site, which increases the workload. In addition, the particulate impurities in the solution can accumulate at the bottom of the pipe and cannot be discharged, causing electrode pollution and inaccurate measurement. When the equipment is overhauled or needs to be emptied for a short period of time, the pH electrode will be exposed to the air for a long time, causing damage and increasing the operating cost of the equipment.
