Specific embodiment
Illustrate embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this specification
Other advantages and efficacy of the present invention can be easily understood for disclosed content.The present invention can also pass through in addition different specific realities
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints and application, without departing from
Various modifications or alterations are carried out under spirit of the invention.It should be noted that in the absence of conflict, following embodiment and implementation
Feature in example can be combined with each other.
It should be noted that illustrating the basic structure that only the invention is illustrated in a schematic way provided in following embodiment
Think, only shown in schema then with related component in the present invention rather than component count, shape and size when according to actual implementation
Draw, when actual implementation kenel, quantity and the ratio of each component can arbitrarily change for one kind, and its assembly layout kenel
It is likely more complexity.
Embodiment one
As shown in Figure 1, the present embodiment provides a kind of dual-seal electrode for electromagnetic flowmeter, which includes
Electrode column 22 and electrode tip holder 21 are provided with one on an end face of electrode tip holder and extend to form from electrode tip holder to far from electrode tip holder direction
Taper platform；Electrode column is set on taper platform；Taper platform is gradually reduced from electrode tip holder to far from electrode tip holder direction；On taper platform
It is provided with first sealing structure 3 for being surrounded on the setting of taper platform；It it is provided with one on the end face of electrode tip holder is surrounded on electrode tip holder and set
The second seals structure 4 set, second seals structure and taper platform are located at the same side of electrode tip holder.
In this present embodiment, the first sealing structure is to be surrounded on the annular notch formed in the middle part of taper platform, the annular notch
Form a line structure.
The present invention is combined application to the sealing structure of electrode, using double sealing structure, to issuable first
Leakage after layer seal failure is again sealed off, and enhances the sealing effect of electrode significantly.
In this present embodiment, taper platform includes the extension diameter section I211 set gradually, undergauge section 212 and extension diameter section II213；Expand
Diameter section I, undergauge section and extension diameter section II are structure as a whole.Preferably, undergauge Duan Weiyi cylindrical body.Further, extension diameter section I
Maximum gauge is equal to the diameter of undergauge section, and the diameter of undergauge section is less than the minimum diameter of extension diameter section II.
In this present embodiment, second seals structure is an annular convex platform 214 being arranged along the edge of electrode tip holder end face.Ring
Shape boss and taper platform, electrode tip holder form a groove structure.
Annular convex platform is R corner structure as a further modification of the present embodiment,.
The installation of dual-seal electrode is as shown in Figure 2.The hole that processing φ d1 is bored on insulation lining, then by electrode from survey
Insertion outside buret, electrode is metal material, and insulation lining is plastics, and electrode material is harder than insulation lining material, in general,
Since the α cone angle and waterline of electrode are to the contention effect of insulating materials, it is close that insulating materials forms sealing ring-i.e. first at waterline
Seal structure, medium are flowed at waterline and are blocked, and form first layer sealing.
If insulated, lining production is defective, and the sealing at waterline goes wrong, and has a small amount of medium to break through first layer sealing,
Enter the groove structure of h1 depth along the conical surface of taper platform.Due to the R corner structure insertion insulation lining of the φ d3 of enclosed electrode, insulation
Lining enters groove structure, becomes the sealing ring of depth h1, outer diameter φ d3, the medium leaked out is kept off in the inside again, is not allowed
It continues to leak.It is illustrated in fig. 3 shown below.
