[0002] PH electrodes, conductivity electrodes, and dissolved oxygen electrodes, as a kind of electrochemical analysis instrument, are widely used from routine to professional measurement, involving petroleum, chemical industry, chemistry, pharmacy, food and various other laboratories or production, etc. The above-mentioned electrodes generally use straight insertion type measurement method to measure related medium in large process pipelines (tanks).

[0003] The existing analysis electrode mounting bracket has the following disadvantages during installation: (1) the insertion depth of the electrode cannot be freely adjusted; (2) when the electrode is replaced, the measurement medium cannot be effectively sealed, which may cause leakage of the measurement medium, and the electrode replacement process is complicated; (3) when the measurement medium contains a large amount of grease, organic matter, metal particles and impurities, the electrode surface may be quickly attached with grease and impurities, which greatly affects the measurement result, and even causes the measurement to be impossible, so the electrode needs to be cleaned regularly. The existing cleaning process is complicated and cannot realize online cleaning. Therefore, the existing process needs to be improved, and a retractable analysis electrode mounting bracket with a flushing port is proposed. SUMMARY

[0004] To overcome the shortcomings of the current electrode mounting bracket and improve the convenience of maintenance and replacement of the straight insertion type measurement analysis electrode of the large process pipeline (tank), the present utility model realizes the functions of online electrode flushing and reduces maintenance cost.

[0005] To achieve the above-mentioned purpose, the utility model takes the technical scheme that:

[0007] Furthermore, a flushing port is provided on the mounting pipe with a flushing interface, which can be connected to external flushing water to flush the electrodes.

[0008] Furthermore, the electrode mounting base is connected to the sensor electrode via an internal thread. One end of the electrode mounting base is made into a protective ball cage to protect the sensor electrode, and the other side is connected to a telescopic probe via an external thread.

[0009] Furthermore, a cable locking cap is provided at the end of the retractable probe away from the electrode mounting base to lock the sensor electrode cable and connect to the tail of the retractable probe.

[0010] Furthermore, an anti-slip sleeve is provided at one end of the retractable probe near the cable locking cap to prevent slippage and facilitate insertion and removal of the retractable probe. The anti-slip sleeve is made of rubber.

[0011] Furthermore, the process flange is made of stainless steel and has a welded external threaded connector for connecting to the isolation ball valve; the isolation ball valve is made of stainless steel and has internal threads on both sides for connecting to the process flange and the mounting pipe with a flushing interface.

[0012] Furthermore, the mounting pipe with the flushing interface is made of stainless steel and has external threads on both sides; the flushing interface is set with internal threads and is used to install plugs or stainless steel compression fittings for easy connection to the flushing water pipe.

[0013] Furthermore, the locking ring is made of stainless steel and has a recessed support on one side for locking the probe seal; the probe seal is made of stainless steel and has an external thread on one side for connecting the probe seal locking ring, and an external convex support on the other side for connecting the locking ring.

After closing the isolation ball valve, the retractable probe can be pulled out by unlocking the locking ring to replace or repair the sensor electrode. This improves the convenience of maintenance and replacement of direct-insertion measurement and analysis electrodes in large process pipelines (tanks). After connecting the flushing port to the flushing water pipe, the sensor electrode can be flushed online, extending the electrode life and greatly reducing the labor intensity of instrument maintenance personnel.
