Specific embodiment
With reference to the accompanying drawing, the present invention is described in more detail.
As shown in Figure 1, ceramic lined electromagnet flow meter sensor high-field electrode encapsulating structure provided by the invention, including pottery
Porcelain liner 1, the ceramic lined are the tubular structure of both ends open, and radially direction offers on the side wall of ceramic lined 1
Two symmetrical mounting holes 101 make its surface metalation using metallization process on the hole wall of two mounting holes 101.
Electrode 2 is equipped in each mounting hole, electrode 2 is the cylindrical structure being prepared by kovar material, the circle
One end of column structure is provided with Gold plated Layer, to increase the corrosion resistance of electrode；The other end offers counterbore 201, for electricity
The connection of pole lead, the electrode 2 are connect by screw with contact conductor.
Wherein, the gap between the metal surface of mounting hole and electrode 2 is 0.05-0.2mm, meanwhile, electrode 2 and ceramic liner
In 1 use Welding；Brazing solder is filled in the gap.
Stainless steel casing in ceramic lined 1 and electromagnetic flowmeter uses hot charging interference mode assembly connection, interference tolerance
For 0.01-0.03mm.
Installation process:
Firstly, electromagnetic flowmeter stainless steel casing is put into high temperature incubator, heating reaches 340 ± 10 DEG C, keeps the temperature 40 points
Clock；Ceramic lined 1 keeps the temperature 30 minutes at 0 DEG C of low temperature incubator；
Later, at the same take out stainless steel casing and ceramic lined 1 Asia envelope tooling platform on be packaged, due in stainless steel
Hole at 340 ± 10 DEG C, in through increasing 0.2mm or so, stainless steel casing is sleeved on ceramic lined 1 at this time, and with ceramics
Installation gap between lining 1 can facilitate installation positioning ceramic lined in 0.15mm；Realize interference fit, make ceramics in
Stainless steel is closely connected up to sealing；Magnitude of interference chooses the excessive ceramic lined after hot charging and is easy pressure break.Magnitude of interference was chosen
Ceramics may be revealed under metal sealing director time service after small hot charging.
Finally, after the installation is completed, room temperature is naturally cooled at normal temperature.
