| titleOfInvention | Cathodic protection monitoring device |
| abstract | The utility model discloses a kind of cathodic protection monitoring devices, belong to oil field equipment field.The device includes: hollow base, push rod, valve, reference electrode, measuring instrument.One end of hollow base and the outer wall of storage tank are tightly connected, and hollow base, which is internally provided with, is provided with through-hole along axial centre bore, the side wall of storage tank, and centre bore is connected to through-hole.Push rod seal is set in centre bore, and can be axially moveable in centre bore, and push rod is arranged in for protruding into one end in storage tank in reference electrode.Valve is arranged on hollow base.Measuring instrument is electrically connected with the side wall of reference electrode, storage tank respectively.The utility model can not only complete the monitoring to reservoir walls current potential, and one end by the way that reference electrode to be arranged in push rod, push rod is contacted with centre bore dynamic sealing, during push rod is pulled out and is protruded into, liquid in storage tank can not be revealed, the replacement of reference electrode can be completed without the liquid in outlet storage tank, use is more convenient. |
