Abstract
The utility model relates to a tungsten-rhenium thermoelectric couple for a vacuum furnace. The special tungsten-rhenium thermoelectric couple for the existing certain vacuum furnaces adopts a solid structure, once a couple wire is broken, the whole thermoelectric couple is discarded, also the special tungsten-rhenium thermoelectric couple for certain vacuum furnaces adopts an old platinum-rhodium-platinum thermoelectric couple structure mode, and the service life is not long and is generally about half a year. The tungsten-rhenium thermoelectric couple comprises a thermal couple body, a couple wire body and a connecting flange, wherein the thermal couple body is formed by welding of a connecting seat and a connecting tube; the couple wire body is provided with the couple wire, a dual-core ceramic tube and an alundum tube in sequence from inside to outside; the couple wire body is arranged in the connecting tube of the thermal couple body; the alundum tube of the couple wire body is connected with the connecting seat of the thermal couple body by inorganic silicon rubber; the bottom part of the connecting seat of the thermal couple body is connected with the connecting flange by bolts, and an insulating seat is arranged between the bottom part of the connecting seat of the thermal couple body and the connecting flange and is provided with a wire-guiding seat; and the couple wire is connected with the wire-guiding seat by nuts. The tungsten-rhenium thermoelectric couple is convenient to replace the couple wire body, thus saving cost, and greatly prolonging the service life which is about two years.
Description
Technical field
The utility model belongs to metallurgy industry, is specifically related to a kind of Wolfram rhenium heat electric couple that is used for vacuum drying oven.
Background technology
In existing vacuum drying oven, measurement of furnace temperature about 1200 ℃～1600 ℃ is mainly with B idol (platinum rhodium-platinum thermocouple), along with domestic Development of Materials, Wolfram rhenium heat electric couple is development rapidly also, in antivacuum stove, obtained widespread use, but in vacuum drying oven, use seldom, the enterprise of domestic a part of professional production thermopair, the special-purpose Wolfram rhenium heat electric couple of the vacuum drying oven of producing adopts the hypostazation structure, and thermo wires one disconnected whole thermopair all takes to fall, and therefore uses also to be restricted, the enterprise of next a part of professional production thermopair, the special-purpose Wolfram rhenium heat electric couple of the vacuum drying oven of producing adopts the version of old-fashioned platinum rhodium-platinum thermocouple, and serviceable life is not long, generally about half a year.
The utility model content
The technical matters that the utility model solved provides a kind of replacing convenience of vacuum drying oven, Wolfram rhenium heat electric couple of saving cost of being used for.
For solving above-mentioned technical matters, the technical scheme that the utility model is taked:
Special character of the present utility model is: comprise thermocouple body, thermo wires body, joint flange, the thermocouple body is made of Connection Block and connecting pipe welding, the thermo wires body sets gradually thermo wires, twin-core ceramic pipe, alundum tube from inside to outside, the thermo wires body is arranged in the connecting pipe of thermocouple body, and the alundum tube of thermo wires body is connected by the Connection Block of inorganic silica gel with the thermocouple body, the bottom of the Connection Block of thermocouple body is connected with joint flange by bolt, and be provided with insulating base between the two, be inserted with wire holder on the insulating base, thermo wires is connected by nut and wire holder.
