Abstract
The utility model relates to an enclosed type flow indicator with an electrode, comprising a casing, the electrode and an insulator. The electrode is arranged in the insulator which is arranged in the casing, and micro gaps are arranged between the electrode and the inner wall of the casing. The fixed end of the casing is provided with external threads, the fixed end is arranged in a liquid pipeline by the external threads, and the sensing end of the other end of the arranged casing is extended into the liquid pipeline. A power supply and a signal device are connected between the leading wire of the electrode and the casing. The utility model has the advantages of simple structure, low cost and reliable work. The structure that the electrode is isolated from fluid in the liquid pipeline is adopted, and the corrosive problem of the electrode is basically solved. The utility model is used for tap water pipelines and pollution discharging pipelines.
Description
The utility model belongs to the fluid parameter field of measuring technique.
In the piping system of tap water and other conveyance fluids, often need measure inlet channel and drainage pipeline and have or not fluid to pass through.Prior art often adopts target formula current indicator and electrode contact current indicator.Target formula current indicator relies on flow action on target and show stream, if dress instead then do not have the stream effect of showing, and stops up easily; Electrode contact current indicator relies on the conductive characteristic that fluid had and shows stream, but in some occasion for example in the blow-off line, electrode corrosion-vulnerable and lose the stream effect of showing.
The closed electrode current indicator that the purpose of this utility model is to provide a kind of electrode and the institute liquid of surveying to completely cut off.
The purpose of this utility model is achieved in that a kind of enclosure-type electrode current indicator, comprises metal shell, electrode and insulator.Metal shell has an endoporus, and electrode is contained on the insulator, and insulator is packed in the metal shell, between electrode and the metal shell endoporus minim gap is arranged.The stiff end of metal shell has external thread, is contained on the fluid pipeline with this external thread, and the other end sensor ends of metal shell stretches in the pipeline.Between contact conductor and metal shell, be connected power supply and telltale circuit.When no liquid in the pipeline circulated, in the metal shell, metal shell and electrode did not come in contact, and circuit is disconnected, and did not have and showed that the stream signal produces; When in the pipeline liquid communication being arranged, stretch into ducted metal shell impression end because of the effect generation that is subjected to liquid stream in the pipeline small deformation tilt, electrode just contacts with metal shell and connects circuit, sends and shows the stream signal.
The utility model has the advantages that simple in structurely, cost is low, adopts electrode and liquid isolation type structure, fundamentally solved the problem that electrode is corroded, so be difficult for to produce fault, reliable operation can be used in waterworks, environmental protection equipment and other conveyings are corrosive the pipeline of fluid.
Fig. 1 is a structural drawing of the present utility model.Fig. 1 is described as follows: 1 is metal shell, and 2 is electrode, and 3 is insulator, and 4 is contact conductor, and 5 is stiff end, and 6 is sensor ends.
