As shown in FIG. 3, in a conventional thermocouple device, a thermocouple element 3 including a heat contact 1 and two thermocouple wires 2 connected to the heat contact 1 is provided in a protective tube 4. It is configured by storing. The insulating tube 5 that insulates and holds the thermocouple wire 2 is formed of an insulating heat-resistant material, and has two through holes 8 that pass through the two thermocouple wires 2 and that hold them insulated from each other. (FIG. 4) is formed in the axial direction. The insulating pipe 5 is formed by connecting a plurality of single insulating pipes 5a (the dimensions of which are, for example, L 1 = 9 to 100 mm and D 1 = about 4 mm in FIG. 5) in the axial direction. There is.
【０００３】 さらに、絶縁管５の先端側には単体絶縁管５ａと同様の貫通孔８（図５）を有 する短い先端絶縁管５ｂ（その寸法は、例えば、図５において、Ｌ2＝約６mm） が接続されており、先端絶縁管５ｂの先端には熱接点１を収納して保護するため のＶ字状の切込み９（その深さは、例えば、図５において、Ｈ1＝約２mm）が形 成されている。そして、絶縁管５の貫通孔８に通され絶縁保持された２本の熱電 対素線２は、保護管４の上部の端子箱６に設けられた２つの端子７に接続されて いる。[0003] Further, a short tip insulating tube 5b (its dimensions have the same through-hole 8 (FIG. 5) and the single insulating tube 5a at the tip end of the insulating tube 5, for example, in FIG. 5, L 2 = about 6 mm), and a V-shaped notch 9 for accommodating and protecting the thermal contact 1 at the tip of the tip insulating tube 5b (the depth is, for example, in FIG. 5, H 1 = about 2 mm ) Is formed. Then, the two thermocouple wires 2 which are passed through the through holes 8 of the insulating tube 5 and insulated and held are connected to the two terminals 7 provided on the terminal box 6 above the protective tube 4.
【０００４】 そして、上記のように構成された従来の熱電対装置においては、熱接点１が、 先端絶縁管５ｂに形成された切込み９と保護管４の底部との間に形成される空間 に収納保持されるとともに、絶縁管５とその先端側に接続された先端絶縁管５ｂ （以下、絶縁管５を構成する単体絶縁管５ａと先端絶縁管５ｂとを合わせて単に 「絶縁管」と呼ぶ場合がある）が、熱接点１と端子７とを接続する熱電対素線２ により吊り下げられたような状態で保護管４内に保持されている。In the conventional thermocouple device configured as described above, the heat contact 1 is provided in the space formed between the notch 9 formed in the tip insulating tube 5b and the bottom of the protection tube 4. The insulation tube 5 is housed and held, and the tip insulation tube 5b connected to the tip side of the insulation tube 5 (hereinafter, the single-piece insulation tube 5a and the tip insulation tube 5b constituting the insulation tube 5 are simply referred to as "insulation tube". However, it is held in the protective tube 4 in a state in which it is suspended by the thermocouple wire 2 connecting the thermal contact 1 and the terminal 7.
【０００５】[0005]
しかし、上記従来の熱電対装置においては、 先端絶縁管の長さが短く、熱 接点１の近くに絶縁管５と先端絶縁管５ｂの継目１０が存在するため、シリカや アルカリの蒸気やヒューム、あるいはＣ０などを含有する雰囲気ガスが継目１０ から絶縁管５及び先端絶縁管５ｂの内部に侵入して熱電対素線２を浸食するため 、熱電対素線２の、継目１０に対応する部分（継目部分）付近の組織が脆くなり 、しかも、 絶縁管５及び先端絶縁管５ｂが熱電対素線２により保持されてい るため（すなわち、絶縁管の全重量が熱電対素線２に加わっているか、あるいは 、絶縁管の全重量が加わっていないまでも相当な荷重が加わっているため）、重 量負荷が集中するとともに、加熱冷却による熱応力も加わり、継目部分付近で熱 電対素線２が断線してしまうという問題点がある。 However, in the above conventional thermocouple device, since the length of the tip insulating tube is short and the joint 10 between the insulating tube 5 and the tip insulating tube 5b exists near the heat contact 1, vapor of silica or alkali, fumes, Alternatively, since the atmospheric gas containing C0 or the like enters the insulating pipe 5 and the tip insulating pipe 5b from the joint 10 to erode the thermocouple wire 2, the portion of the thermocouple wire 2 corresponding to the joint 10 ( The structure around the joint becomes brittle, and the insulating tube 5 and the tip insulating tube 5b are held by the thermocouple element 2 (that is, the total weight of the insulating tube is added to the thermocouple element 2). Or, since a considerable load is applied even if the total weight of the insulation pipe is not applied), the heavy load is concentrated and the thermal stress due to heating and cooling is also applied, and the thermocouple wire 2 is added near the joint. Is broken There is a problem that the Mau.
【０００６】 この考案は、上記従来の熱電対装置の問題点を解決するものであり、絶縁管内 への雰囲気ガスの侵入を抑制するとともに、熱電対素線への重量負荷を軽減する ことにより、熱電対素線の断線を防止して、熱電対装置の耐久性を向上させるこ とを目的とする。This invention solves the problems of the above-mentioned conventional thermocouple device, and suppresses the invasion of atmospheric gas into the insulating tube and reduces the weight load on the thermocouple wire. The purpose is to prevent breakage of the thermocouple wire and improve the durability of the thermocouple device.
【０００７】[0007]
上記の目的を達成するために、この考案の熱電対装置は、熱接点と、前記熱接 点から導出され、先端に先端絶縁管を接続した絶縁管内に挿入することにより互 に絶縁保持された２本の熱電対素線とを備えた熱電対素子を保護管内に収納して 形成した熱電対装置において、熱電対素線を絶縁保持する絶縁管の先端部に接続 された先端絶縁管の長さを長くして、熱接点に近い部分に絶縁管と先端絶縁管の 継目が形成されないようにするとともに、先端絶縁管の先端部に切込みを形成し 、該切込みの深さを深くして、保護管の底部に先端絶縁管の先端部が当接した状 態において、保護管の底部と該切込みとにより形成される空間内に熱接点を収納 できるようにしたことを特徴としている。 In order to achieve the above-mentioned object, the thermocouple device of the present invention is insulated from each other by being inserted into an insulation tube which is led out from the heat contact point and the heat contact point and has a tip insulation tube connected to the tip.

The present invention is characterized in that the heat contact can be housed in the space formed by the bottom of the protection tube and the cutout in a state where the tip of the tip insulating tube is in contact with the bottom of the protection tube.
【０００８】[0008]
この考案の熱電対装置は、熱電対素線の熱接点側の部分が挿入される先端絶縁 管の長さが長いため、熱接点に近い部分に絶縁管と先端絶縁管との継目がなく、 シリカやアルカリの蒸気やヒューム、あるいはＣ０などを含有する雰囲気ガスが 継目から絶縁管の内部に侵入して熱電対素線の組織を部分的に脆化することを効 果的に防止することができる。 In the thermocouple device of the present invention, since the length of the tip insulating tube into which the part of the thermocouple wire on the side of the heat contact is inserted is long, there is no joint between the insulating tube and the tip insulating tube in the part near the heat contact. It is possible to effectively prevent the atmosphere gas containing silica, alkali vapor, fume, or C0 from entering the inside of the insulating tube from the joint and embrittleing the structure of the thermocouple wire partially. it can.

【００１０】[0010]
以下、この考案の実施例を図に基づいて説明する。図１は、この考案の一実施 例にかかる熱電対装置を示す断面図である。図１に示すように、この実施例の熱 電対装置は、熱接点１と、この熱接点１と接続する２本の熱電対素線（この実施 例では白金線）２とを備えた熱電対素子３を、保護管４内に収納することにより 形成されている。熱電対素線２を絶縁保持する絶縁管５は、ハイアルミナ質の耐 火材料から形成されており、その直径Ｄ2（図２）は、約４mmであり、２本の熱 電対素線２を貫通させ、これを互に絶縁して保持する直径約１mmの２つの貫通孔 ８がその軸方向に形成されている。この絶縁管５は、継目が生じないように一体 に形成されたものを用いてもよく、また、従来例のように、単体絶縁管５ａ（図 ３）を複数個、軸方向に接続して形成したものを用いることも可能である。そし て、絶縁管５の貫通孔８に通され絶縁保持された２本の熱電対素線２は、保護管 ４の上部の端子箱６に設けられた端子７に接続されている。An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a thermocouple device according to an embodiment of the present invention. As shown in FIG. 1, the thermocouple device of this embodiment includes a thermoelectric contact 1 and two thermocouple wires (platinum wire in this embodiment) 2 connected to the thermoelectric contact 1. It is formed by housing the paired element 3 in the protective tube 4. The insulating tube 5 that insulates and holds the thermocouple wire 2 is made of a high-alumina refractory material, and has a diameter D 2 (Fig. 2) of about 4 mm and two thermocouple wires. Two through holes 8 having a diameter of about 1 mm are formed in the axial direction so as to pass through the two holes and hold them insulatively. The insulating tube 5 may be integrally formed so that no seam is formed, or, as in the conventional example, a plurality of single insulating tubes 5a (FIG. 3) are connected in the axial direction. It is also possible to use what was formed. Then, the two thermocouple wires 2 which are passed through the through holes 8 of the insulating tube 5 and are insulated and held are connected to the terminals 7 provided on the terminal box 6 above the protective tube 4.
【００１１】 さらに、絶縁管５の先端側には、先端絶縁管５ｂが接続されており、その長さ は、従来の先端絶縁管５ｂの長さＬ2＝約６mm（図５）より相当に長く、例えば 、図２において、Ｌ3＝約１００mmの長さに形成されており、従来例の先端絶縁 管５ｂ（約６mm）とそれに隣接する単体絶縁管５ａ（例えば、約９mm）（図５） とを合わせた長さより大幅に長くなっている。したがって、先端絶縁管５ｂの先 端部（熱接点１を露出させた位置）から約１００mmの距離の絶縁管５との継目１ ０までは継目が存在しない。Further, a tip insulating tube 5b is connected to the tip side of the insulating tube 5, and its length is considerably longer than the length L 2 of the conventional tip insulating tube 5b = about 6 mm (FIG. 5). The length is long, for example, L 3 = about 100 mm in FIG. 2, and the tip insulating tube 5 b (about 6 mm) of the conventional example and the single unit insulating tube 5 a adjacent to it (for example, about 9 mm) (FIG. 5) ) Is significantly longer than the combined length. Therefore, there is no seam from the tip of the tip insulating tube 5b (the position where the heat contact 1 is exposed) to the seam 10 with the insulating tube 5 at a distance of about 100 mm.
【００１２】 また、先端絶縁管５ｂの先端（下端）には、熱接点１を収納する空間となるＶ 字状の切込み９が形成されており、この切込み９は、先端絶縁管５ｂの先端部を 保護管４の底部に当接させた状態で熱接点１を収納することが可能な深さ（その 寸法は、例えば、図２において、Ｈ2＝約３．５mm）に形成されている。Further, a V-shaped notch 9 serving as a space for accommodating the thermal contact 1 is formed at the tip (lower end) of the tip insulating tube 5b, and the notch 9 is a tip portion of the tip insulating tube 5b. Is formed to have a depth (the size is, for example, H 2 = about 3.5 mm in FIG. 2) in which the thermal contact 1 can be accommodated in a state where the thermal contact 1 is brought into contact with the bottom of the protective tube 4.
【００１３】 上記のように構成されたこの実施例の熱電対装置においては、先端絶縁管５ｂ の長さが長く、熱接点１に近い部分に継目がないため、シリカやアルカリの蒸気 やヒューム、あるいはＣ０などを含有する雰囲気ガスが継目から内部に侵入して 熱電対素線２を浸食するようなことがなく、熱電対素線２の部分的な脆化を確実 に抑制することができる。In the thermocouple device of this embodiment configured as described above, since the length of the tip insulating tube 5b is long and the portion near the heat contact 1 is seamless, silica or alkali vapor or fume, Alternatively, the atmospheric gas containing C0 or the like does not intrude into the interior from the joint to erode the thermocouple wire 2, and it is possible to reliably suppress partial embrittlement of the thermocouple wire 2.
【００１４】 また、先端絶縁管５ｂの先端部に十分な深さの切込み９が形成されているため 、先端絶縁管５ｂの先端部を保護管４の底部に当接させた状態で、熱接点１を、 該切込み９と保護管４の底部との間に形成される空間内に収納することができる ため、絶縁管５を保護管４に挿入し、先端絶縁管５ｂの先端部を保護管４の底部 に当接させることにより、熱電対素線２にかかる重量負荷を確実に排除すること ができる。Further, since the notch 9 having a sufficient depth is formed at the tip of the tip insulating tube 5b, the thermal contact is made while the tip of the tip insulating tube 5b is in contact with the bottom of the protection tube 4. 1 can be accommodated in the space formed between the notch 9 and the bottom of the protective tube 4, so the insulating tube 5 is inserted into the protective tube 4 and the tip of the tip insulating tube 5b is protected by the protective tube. By making contact with the bottom portion of the thermocouple wire 4, the weight load on the thermocouple wire 2 can be reliably eliminated.
【００１５】 したがって、この考案によれば、熱電対素線の部分的な脆化を抑制し、かつ、 熱電対素線にかかる重量負荷を排除することにより、熱電対素線の断線を防止し て、耐用回数を大幅に向上させることができる。Therefore, according to the present invention, it is possible to prevent the thermocouple wires from breaking by suppressing partial embrittlement of the thermocouple wires and eliminating the weight load applied to the thermocouple wires. Thus, the service life can be greatly improved.
【００１６】 なお、この考案にかかる熱電対装置を、耐火物の荷重軟化試験（還元性雰囲気 下、１７２０℃まで昇温）に実際に使用した場合において、従来の熱電対装置の 耐用回数が２１回であったのに対して、この考案の実施例にかかる熱電対装置は ４６回の使用に耐えることを確認することができた。When the thermocouple device according to the present invention is actually used in a load softening test of refractory (heated up to 1720 ° C. in a reducing atmosphere), the conventional thermocouple device has a service life of 21 times. It can be confirmed that the thermocouple device according to the embodiment of the present invention can withstand 46 uses.
【００１７】 このように、この考案の熱電対装置は、還元性雰囲気の耐火物高温焼成炉や、 試験炉などの温度測定に有効に利用することができる。また、この考案の熱電対 装置は、還元性雰囲気の場合に限らず、中性雰囲気や酸化性雰囲気の場合にも用 いることが可能である。As described above, the thermocouple device of the present invention can be effectively used for temperature measurement of a refractory high temperature firing furnace in a reducing atmosphere, a test furnace, or the like. The thermocouple device of the present invention can be used not only in a reducing atmosphere but also in a neutral atmosphere or an oxidizing atmosphere.
【００１８】 上記実施例においては、先端絶縁管の長さを、約１００mm、切込みの深さを約 ３．５mmにした場合について説明したが、この考案の熱電対装置においては、先 端絶縁管の長さＬ3は５０mm以上であることが望ましく、また、切込みの深さＨ2 は、測定の精度などを考慮すると、約３〜７mmの範囲にあることが好ましい。但 し、必ずしもこれらの数値に制約されるものではなく、使用条件などに応じて適 切な値を設定することが可能である。Although the length of the tip insulating tube is set to about 100 mm and the depth of the cut is set to about 3.5 mm in the above embodiment, the tip end insulating tube is set in the thermocouple device of the present invention. It is preferable that the length L 3 is 50 mm or more, and the depth H 2 of the cut is preferably in the range of about 3 to 7 mm in consideration of measurement accuracy and the like. However, it is not necessarily limited to these numerical values, and it is possible to set an appropriate value according to usage conditions.
【００１９】 さらに、上記実施例においては、絶縁管５，先端絶縁管５ｂの構成材料として 、耐熱性、耐食性に優れたハイアルミナ質の耐火材料を用いた場合について説明 したが、この考案の熱電対装置においては、絶縁管の材質は必ずしもハイアルミ ナ質の耐火材料に限られるものではなく、耐熱性などの基本的特性を備えた種々 の材料を用いることが可能である。Further, in the above-mentioned embodiment, the case where a high alumina refractory material excellent in heat resistance and corrosion resistance is used as a constituent material of the insulating tube 5 and the tip insulating tube 5b has been described. In the device, the material of the insulating tube is not necessarily limited to the high-alumina refractory material, but various materials having basic characteristics such as heat resistance can be used.
【００２０】 また、熱接点、熱電対素線、保護管などの材質についても、特別の制約はなく 、使用目的や使用条件などに応じ、種々の材料を用いて構成することが可能であ り、またその形状についても特別な制約はない。There are no particular restrictions on the materials of the heat contacts, thermocouple wires, protective tubes, etc., and various materials can be used according to the purpose of use and conditions of use. Also, there is no special restriction on its shape.
【００２１】[0021]
上述のように、この考案の熱電対装置は、先端絶縁管の長さを長くして、熱接 点に近い部分に継目が形成されないようにするとともに、先端絶縁管の先端部の 切込みの深さを深くし、先端絶縁管の先端部を保護管の底部に当接させた状態で 、熱接点を保護管の底部と切込みとの間に形成された空間に収納できるようにし ているので、絶縁管内への雰囲気ガスの侵入を防止するとともに、熱電対素線に かかる重量負荷を除去して熱電対素線の断線を防止し、熱電対装置の耐久性を大 幅に向上させることができる。 As described above, in the thermocouple device of the present invention, the length of the tip insulating tube is increased so that the seam is not formed in the portion close to the heat contact point, and the depth of the notch at the tip of the tip insulating tube is increased. By making the depth deeper and making the tip of the tip insulation tube abut on the bottom of the protection tube, the heat contact can be stored in the space formed between the bottom of the protection tube and the notch. In addition to preventing atmospheric gas from entering the insulation tube, removing the weight load on the thermocouple wire to prevent breakage of the thermocouple wire, the durability of the thermocouple device can be greatly improved. .
