Abstract
The utility model discloses a combined electrode for an electromagnetic flow-meter, which comprises an electrode stem and an electrode saddle, wherein external threads are formed at one end of the electrode stem, and internal threads are formed at the other end of the electrode stem; the internal threads are formed at one end of the electrode saddle; and the electrode stem and the electrode saddle are connected through screw threads. The compound electrode is divided into two parts; and if one part is damaged, as long as the corresponding part is replaced, the other part can still be used continuously, so that the production cost can be lowered. Furthermore, as the electrode saddle of the compound electrode is made of rare metal and the electrode stem is made of stainless steel, compared with prior art, the consumption of rare metal is reduced greatly, the production cost is lowered, and the processing difficulty of stainless steel is smaller as compared with the rare metal.
Description
Technical field
The utility model relates to the electrode of using on a kind of electromagnetic flowmeter, is specifically related to a kind of detachable electrode.
Background technology
At present, electromagnetic flowmeter is used widely in the flow measurement of liquid, generally comprises electrode, sensor etc.The signal voltage of flowmeter is to apply the magnetic field that exciting current produces and between pair of electrodes, produce through fluid.Symmetry is installed two potential electrode on the same circular section of measuring tube.The electrode shape of traditional electrical magnetic flowmeter is the different Rotary-table of two ends diameter, and wherein the big end of electrode contacts with measured medium towards the tube wall inboard, and the small end of electrode is exposed to outside the tube wall through the electrode mounting hole that is provided with lining, does not contact measured medium.According to the difference of measured medium, the electrode material is generally metal materials such as containing molybdenum stainless steel, Hastelloy B, Hastelloy C, titanium, tantalum, platinumiridio.When the electrode material was rare metal, its manufacturing cost was high, difficulty of processing is big.And if electrode is when being damaged, its sealing variation needs whole replacing electrode, has further increased cost.
The utility model content
The technical matters that the utility model will solve is that the electrode cost on the existing electromagnetic flowmeter is high, provides the low electromagnetic flowmeter of a kind of cost to use compound electrode.
The technical scheme of the utility model realizes in the following manner: a kind of electromagnetic flowmeter is used compound electrode; Comprise electrode stem and electrode saddle; Electrode stem one end is provided with external thread, an end is provided with internal thread; One end of electrode saddle is provided with internal thread, links to each other through screw thread between electrode stem and the electrode saddle.
Said electrode stem is the electrode stem of stainless steel, and the electrode saddle is the electrode saddle of rare metal.
The described electrode of the utility model is divided into two parts and forms, if wherein a part is damaged, only needs to change appropriate section and gets final product, and a part still can continue to use in addition, can reduce production costs.In addition, the electrode saddle is the rare metal material in the utility model, and electrode stem is a stainless steel, compared with prior art, has significantly reduced the consumption of rare metal, has reduced production cost, and has compared rare metal, and the stainless steel difficulty of processing is little.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The described electromagnetic flowmeter of the utility model comprises electrode stem 1 and electrode saddle 2 with compound electrode; Electrode stem 1 one ends are provided with external thread, an end is provided with internal thread, and an end of electrode saddle 2 is provided with internal thread, link to each other through screw thread between electrode stem 1 and the electrode saddle 2.
Said electrode stem 1 is the electrode stem of stainless steel, and electrode saddle 2 is the electrode saddle of rare metal.
In the use; Electrode stem 1 is in the same place through being threaded with electrode saddle 2, and the lower end of electrode saddle 2 contacts with fluid to be measured, and the upper end of electrode stem 1 is exposed at the outside of measuring tube; The nut of on the electrode stem that exposes 1, screwing on can make electrode stem 1 well be fixed on the measuring tube.Have more the difference of measured medium, can select the electrode saddle 2 of unlike material preparation.
