Description
Technical field
The utility model relates to a kind of reference electrode that recycles, and belongs to the oil and gas pipeline technical field.
Background technology
Mainly adopt cathode protecting process control pipeline to corrode outward for buried steel pipeline; the indispensable measurement integral part of reference electrode impressed current type cathodic protection system; if reference electrode occurs unusual; to cause potentiostat measurement signal mistake; cause the potentiostat output abnormality, pipeline can't obtain galvanic protection and effectively protect.The multiple conventional reference electrode of using in the present engineering; be applicable to the area that geographic climate is more moistening; and in the desert, dry area such as Gobi desert, barren beach; this conventional reference electrode has a strong impact on work-ing life because internal solution runs off; reference electrode life-time service internal solution and soil intermediate ion exchange in addition, cause ionic soil, cause reference electrode to lose efficacy; the potentiostat operation irregularity, cathodic protection system smooth working for a long time.Need a kind of reference electrode that is applicable to dry area and can regularly replaces internal solution for this reason.
Improve the reference electrode reliability, reduce potentiostat operation irregularity situation, guarantee that the pipeline cathode protection system is effective, prolong the pipeline service life.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of reference electrode that recycles.
A kind of reference electrode that recycles, insulated shell is connected with lower end cover with upper end cover; Fill copper/saturated copper sulphate solution in the enclosed space of insulated shell and upper end cover and lower end cover; Copper electrode is placed in the copper-bath;
Copper electrode connection electrode line; Electrode wires is installed in the electrode wires sealing cover; The electrode wires sealing cover is connected with upper end cover; Water filling port, water port are stamped in the upper end; Pass the water filling conduit in the water filling port; One end of water filling conduit is in the bottom of insulated shell; Water port is passed drainage duct;
Pottery infiltration module is connected with lower end cover.
Copper electrode is spiral-shaped.
Wherein shell 1 and upper end cover 2, lower end cover 3 are formed the agent structures of reference electrodes jointly, and material therefor is insulating material such as high-strength PVC, engineering plastics ABS or synthetic glass.
The utility model is the galvanic protection reference electrode that is applicable to dry areas such as desert, Gobi desert, barren beach.Relating to the field is to adopt the galvanic protection of impressed current type.
The utility model characteristics in:
1) increases the recycle system, both can regularly replace the reference internal solution again, the measuring error of avoiding ionic soil to cause for reference electrode in time replenishes copper/saturated copper sulphate solution;
2) adopt porosity is littler, density is higher high-performance ceramic as the ion-exchange passage, reduce the loss of solution, improve reference duration of service greatly;
3) reference electrode internal copper electrode adopts volution, can increase the area of ion and copper electrode reaction, makes reference potential more stable.
The utility model has the advantages that the utility model circulation reference electrode has overcome the deficiency of existing reference electrode, solve reference by the increase recycle system and replenished, changed copper/saturated copper sulphate solution problem, the realization reference electrode recycles, and avoids ionic soil to cause measuring error.Adopt high-performance ceramic as the ion-exchange passage, reduce the loss of solution.Adopt the volution copper electrode, increase the area of ion and copper electrode reaction, make reference potential more stable.Improve the reference electrode reliability, reduce potentiostat operation irregularity situation, guarantee that the pipeline cathode protection system is effective, prolong the pipeline service life.Use for reference existing reference electrode structure, the increase recycle system has solved reference and has replenished, changed copper/saturated copper sulphate solution problem, makes it be suitable for the use of dry area more.
