Description

本発明は、シース測温抵抗体やシース熱電対などのシース温度計を保護管内に挿着して構成される温度測定器に係り、特に、温度検出のタイムラグを小さくできる優れた応答性を示し、例えば重合体反応器の温度測定などに好適に用いられる温度測定器に関する。   The present invention relates to a temperature measuring device configured by inserting a sheath thermometer such as a sheathed resistance thermometer or a sheathed thermocouple into a protective tube, and in particular, exhibits excellent responsiveness capable of reducing the time lag of temperature detection. For example, the present invention relates to a temperature measuring device suitably used for measuring the temperature of a polymer reactor.

この種の温度計測器としては、従来、保護管とシース温度計の先端の隙間に良熱伝導性金属を充填してこれらの密着性を向上させたものや、保護管とシース温度計の先端接合部にネジを設けてこれらの密着性を向上させたものが提案されている(例えば、特許文献1、2参照。)。応答性の改善には、保護管外径と挿入長の比率(アスペクト比)をできるだけ大きく取ること以外に、シースと保護管の熱的接触をできるかぎり確保することが肝要であり、上記提案により熱的接触が確保され、応答性の改善に貢献できる。   Conventionally, this type of temperature measuring instrument has a good thermal conductivity metal filled in the gap between the tip of the protective tube and the sheath thermometer to improve their adhesion, or the tip of the protective tube and the sheath thermometer. The thing which provided the screw | thread in the junction part and improved these adhesiveness is proposed (for example, refer patent document 1, 2). In order to improve responsiveness, it is important to ensure the thermal contact between the sheath and the protective tube as much as possible, in addition to taking the ratio between the outer diameter of the protective tube and the insertion length (aspect ratio) as large as possible. Thermal contact is ensured, contributing to improved responsiveness.

しかしながら、良熱伝導性金属を充填するもの(特許文献1の提案)では、熱伝導の向上により応答性が向上するものの、良熱伝導性金属として液体金属が使用され、取付方向が常に下方向でなければならず上方向や横方向に取り付けると充填した良熱伝導性金属が漏れ出てくること、良熱伝導性金属が変質した場合にはその特性が変化するために長期的に安定した温度測定が困難となるといった問題がある。また、保護管とシース温度計の先端接合部にネジを設けたもの(特許文献2の提案)では、簡単に脱着できるものではなく、さらに埃等がネジ部に噛み込んだりすれば、脱着が不可能となる場合もある。   However, in the case of filling with a good heat conductive metal (proposed in Patent Document 1), the response is improved by improving the heat conduction, but a liquid metal is used as the good heat conductive metal, and the mounting direction is always downward. If it is installed in the upward or lateral direction, the filled metal with good heat conductivity will leak, and if the metal with good heat conductivity changes, its characteristics will change and stable for a long time. There is a problem that temperature measurement becomes difficult. In addition, in the case where a screw is provided at the joint portion between the protective tube and the sheath thermometer (proposed in Patent Document 2), it cannot be easily detached, and if dust or the like bites into the threaded portion, it can be detached. It may not be possible.

これに対し、シース温度計の検出部の外径と保護管の内径との隙間を特定の範囲内とすることで、上記液体金属等の充填物が存在せずネジ込み等の構造もなく、保護管からのシース温度計の脱着が容易であるとともに優れた応答性も維持できる温度測定器が提案されている(特許文献3参照)。しかし、このような微小隙間を設けるものでは応答性の更なる向上には一定の限界があるとともに、製造管理・コストもかかり、保護管が外部から振動を受けた場合には熱的接触状態が不安定となって応答性にズレが生じる虞もある。   On the other hand, by making the gap between the outer diameter of the detection part of the sheath thermometer and the inner diameter of the protective tube within a specific range, there is no filling such as the above liquid metal and there is no structure such as screwing, There has been proposed a temperature measuring device that can easily attach and detach a sheath thermometer from a protective tube and can maintain excellent responsiveness (see Patent Document 3). However, in the case of providing such a minute gap, there is a certain limit to further improving the response, and manufacturing management and cost are also required. When the protective tube receives vibration from the outside, the thermal contact state is not achieved. There is also a risk that the response will be shifted due to instability.

そこで、本発明が前述の状況に鑑み、解決しようとするところは、シース温度計と保護管との熱的接触を確保し、温度検出における優れた応答性を発揮できるとともに、保護管内へのシース温度計の脱着作業を容易に行うことができ、製造・管理コストも大幅に削減できる温度測定器を提供する点にある。   Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the thermal contact between the sheath thermometer and the protective tube is ensured, and excellent responsiveness in temperature detection can be exhibited and the sheath into the protective tube can be exhibited. The object of the present invention is to provide a temperature measuring instrument that can easily remove and install the thermometer and can greatly reduce the manufacturing and management costs.

本発明は、前述の課題解決のために、シース温度計を保護管内に装着してなる温度測定器において、押圧部材を用いてシース温度計を保護管内壁に圧接させたことを特徴とする温度測定器を構成した。ここで、前記押圧部材が、シース温度計の外周面上に、長手方向に沿って外方に湾曲した形状の線状または板状のバネ材であり、これを1つ又は長手方向に複数設け、当該バネ材の湾曲形状部を保護管内壁に当接変形させ、その弾性復元力によりシース温度計外周面のバネ材と反対側の部位を保護管内壁に圧接する構成であることが好ましい。   In order to solve the above-mentioned problems, the present invention provides a temperature measuring device in which a sheath thermometer is mounted in a protective tube, and a temperature characterized by pressing the sheath thermometer against the inner wall of the protective tube using a pressing member. A measuring instrument was constructed. Here, the pressing member is a linear or plate-like spring material curved outward along the longitudinal direction on the outer peripheral surface of the sheath thermometer, and one or a plurality of the spring members are provided in the longitudinal direction. The curved shape portion of the spring material is preferably brought into contact with and deformed against the inner wall of the protective tube, and the elastic thermosetting force is used to press the portion of the outer surface of the sheath thermometer opposite to the spring material against the inner wall of the protective tube.

また、前記バネ材の少なくとも一端側を、前記シース温度計外周面に対して長手方向に摺動する自由端とし、該自由端に略T字状ないし略Y字状に左右に膨出した摺動受け部を設けてなるものが好ましい。   Further, at least one end side of the spring material is a free end that slides in the longitudinal direction with respect to the outer peripheral surface of the sheath thermometer, and a slide that bulges left and right in a substantially T shape or a substantially Y shape at the free end. What provided the moving part is preferable.

また、前記バネ材が、長手方向に湾曲形状部を二つ以上連設してなり、これら湾曲形状部の間の所定位置を前記シース温度計外周面に固定するとともに、両端側をそれぞれ前記シース温度計外周面に対して長手方向に摺動する自由端としてなるものが好ましい。   Further, the spring material is formed by connecting two or more curved shape portions in the longitudinal direction, fixing a predetermined position between the curved shape portions to the outer peripheral surface of the sheath thermometer, and both ends on the sheath side. What becomes a free end which slides to a longitudinal direction with respect to a thermometer outer peripheral surface is preferable.

或いは、前記バネ材の一端側を前記シース温度計外周面に固定するとともに、他端側を前記シース温度計外周面に対して長手方向に摺動する自由端としてなるものも好ましい実施例である。   Alternatively, a preferred embodiment is one in which one end side of the spring material is fixed to the outer surface of the sheath thermometer and the other end is a free end that slides in the longitudinal direction with respect to the outer surface of the sheath thermometer. .

以上にしてなる本願発明に係る温度測定器は、押圧部材によりシース温度計外周面の任意の部位を保護管内壁に圧接させることで、確実且つ容易に直接的な熱伝導を行い、温度検出における優れた応答性を発揮することができる。また、バネ材の湾曲形状部を保護管内壁に当接変形させ、その弾性復元力によりシース温度計外周面のバネ材と反対側の部位を保護管内壁に圧接させる構成とすることで、簡単な構造で確実且つ容易に直接的な熱伝導を行い、温度検出における優れた応答性を発揮することができる。また、バネ材のサイズや数を設定するだけでシース温度計の任意の長さ部位を保護管内壁に圧接させることが可能であり、用途や保護管、シース温度計の種類やサイズに応じて適した熱的接触状態を容易且つ低コストに得ることができる。   In the temperature measuring device according to the present invention as described above, direct heat conduction is reliably and easily performed by pressing any portion of the outer surface of the sheath thermometer against the inner wall of the protective tube by the pressing member, and in temperature detection. Excellent responsiveness can be exhibited. In addition, the curved shape part of the spring material is contacted and deformed to the inner wall of the protective tube, and the elastic restoring force is used to press the portion of the outer surface of the sheath thermometer opposite to the spring material to the inner wall of the protective tube. It is possible to perform direct heat conduction reliably and easily with a simple structure and exhibit excellent responsiveness in temperature detection. In addition, it is possible to press the length of the sheath thermometer to the inner wall of the protective tube simply by setting the size and number of the spring material, depending on the application and the type and size of the protective tube and sheath thermometer. A suitable thermal contact state can be obtained easily and at low cost.

また、脱着操作は、外周面上にバネ材を取り付けたシース温度計を保護管内に挿着/離脱させるだけの簡易な操作で可能となり、またバネ材は長手方向に延びる線状又は板状のバネであるため脱着の際に保護管内壁が多少荒れていてもバネ材の引掛かりや歪みが生じることもなくスムーズに操作でき、屈曲した保護管に対して追従できる自由度もある。また従来の提案のような充填物の漏れ出しの虞やネジ部の固着等の虞もなく、また挿着状態においてはバネ材はシース温度計の外周面上に安定した姿勢が維持され、振動等によっても熱的接触状態は安定し、応答性のブレもほとんど生じない精度の高い測定が可能となる。   In addition, the detachment operation can be performed by a simple operation of simply inserting / removing a sheath thermometer with a spring material on the outer peripheral surface thereof into / from the protective tube, and the spring material is a linear or plate-like shape extending in the longitudinal direction. Since it is a spring, even if the inner wall of the protective tube is somewhat rough during attachment / detachment, it can be operated smoothly without catching or distorting the spring material, and there is a degree of freedom to follow a bent protective tube. In addition, there is no risk of leakage of the packing material or sticking of the screw portion as in the conventional proposal, and in the inserted state, the spring material maintains a stable posture on the outer peripheral surface of the sheath thermometer, and vibration is generated. The thermal contact state can be stabilized even by the above, and highly accurate measurement with little responsive blurring can be performed.

また、バネ材の自由端に略T字状ないし略Y字状に左右に膨出した摺動受け部を設けたので、該摺動受け部がシース温度計の外周面上を長手方向に移動してバネ材のスムーズな変形が可能となり、またその弾性復元力が安定してシース温度計に作用する。また、この変形容易性により保護管内への挿着操作が極めて容易となり、安定した弾性復元力の作用により保護管内壁への良好な圧着状態が確保される。   In addition, since a slide receiving portion bulging left and right in a substantially T or Y shape is provided at the free end of the spring material, the slide receiving portion moves in the longitudinal direction on the outer peripheral surface of the sheath thermometer. Thus, the spring material can be smoothly deformed, and its elastic restoring force stably acts on the sheath thermometer. In addition, due to the ease of deformation, the insertion operation into the protective tube becomes extremely easy, and a good crimping state to the inner wall of the protective tube is ensured by the action of a stable elastic restoring force.

また、バネ材が長手方向に湾曲形状部を二つ以上連設してなり、これら湾曲形状部の間の所定位置をシース温度計外周面に固定するとともに両端側を自由端としたので、シース温度計の比較的長い範囲を保護管内壁に安定且つ均一に圧着させることが可能となる。   In addition, the spring material is formed by connecting two or more curved portions in the longitudinal direction, and a predetermined position between the curved portions is fixed to the outer surface of the sheath thermometer and both ends are free ends. A relatively long range of the thermometer can be stably and uniformly crimped to the inner wall of the protective tube.

また、バネ材の一端側をシース温度計外周面に固定するとともに、他端側を自由端としたので、シース温度計の比較的短い範囲に絞って保護管内壁に圧着させることができ、例えば先端部に感温長さがあるシース測温抵抗体などの場合に特に有効である。   In addition, since one end side of the spring material is fixed to the outer surface of the sheath thermometer and the other end side is a free end, it can be crimped to the inner wall of the protective tube by narrowing to a relatively short range of the sheath thermometer, for example This is particularly effective in the case of a sheathed resistance temperature detector having a temperature sensitive length at the tip.

次に、本発明の実施形態を添付図面に基づき詳細に説明する。   Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図1(a)は、本発明に係る温度測定器の全体構成を示す図であり、図1〜7は第1実施形態、図8は第2実施形態を示し、図中符号1は温度測定器、2はシース温度計、3は保護管、4はバネ材をそれぞれ示している。   FIG. 1A is a diagram showing an overall configuration of a temperature measuring device according to the present invention. FIGS. 1 to 7 show a first embodiment, FIG. 8 shows a second embodiment, and reference numeral 1 in the drawing denotes temperature measurement. 2 is a sheath thermometer, 3 is a protective tube, and 4 is a spring material.

第1実施形態の温度測定器1は、図1(a),(b)に示すように、シース温度計2を保護管3内に装着して構成されるものであり、特に、シース温度計2の外周面20上の径方向所定角度部位20aに、長手方向に沿って外方に湾曲した形状の湾曲形状部5,5を備えるバネ材4を設けて、当該バネ材4の湾曲形状部5,5を保護管内壁30aに当接変形させ、その弾性復元力によりシース温度計外周面20のバネ材4と反対側の部位20bを保護管内壁30bに圧接させたことを特徴としている。   As shown in FIGS. 1A and 1B, the temperature measuring device 1 according to the first embodiment is configured by mounting a sheath thermometer 2 in a protective tube 3, and in particular, a sheath thermometer. The spring material 4 including the curved shape portions 5 and 5 having a shape curved outward along the longitudinal direction is provided at a predetermined radial angle portion 20a on the outer peripheral surface 20 of the second circumferential surface 20, and the curved shape portion of the spring material 4 is provided. 5 and 5 are brought into contact with and deformed against the inner wall 30a of the protective tube, and a portion 20b of the outer surface 20 of the sheath thermometer opposite to the spring material 4 is pressed against the inner wall 30b of the protective tube by its elastic restoring force.

なお、シース温度計2は、従来から公知の種々の用途に応じた各種シース熱電対やシース測温抵抗体などを適用でき、保護管3についても前記シース熱電対やシース測温抵抗体などとともに従来から使用されている公知のものを使用できる。また、用途としては、上記した技術分野の説明において重合用反応器に好適であることを挙げたが、本発明はこのような用途に限定されるものではなく、例えば耐食性が高く被処理物へのコンタミ(汚染)を防止できるがその反面応答性に課題があるガラスライニング温度計に適用すると、応答性の高い温度計を得ることができ好ましい。また、バネ材4は、これらシース温度計2と保護管3の寸法等に応じて、上記弾性復元力よる圧接機能を発揮しうるような適宜な寸法(太さ、形状)に設定すればよい。   The sheath thermometer 2 can be applied with various sheathed thermocouples and sheathed resistance thermometers according to various conventionally known applications, and the protective tube 3 together with the sheathed thermocouples and sheathed resistance thermometers, etc. The well-known thing used conventionally can be used. In addition, as an application, it has been mentioned that it is suitable for a polymerization reactor in the above description of the technical field, but the present invention is not limited to such an application. For example, it has high corrosion resistance and can be processed. However, when applied to a glass lining thermometer having a problem in response, a thermometer having high response can be obtained. Further, the spring material 4 may be set to an appropriate size (thickness, shape) that can exert the pressure contact function by the elastic restoring force according to the dimensions of the sheath thermometer 2 and the protective tube 3. .

バネ材4は、屈曲した線材より構成されており、図2にも示すように、長手方向に湾曲形状部5,5が二つ連設され、これら湾曲形状部5,5の間のシース温度計外周面20上に当接する所定位置(略中央位置)40がシース温度計2の外周面20上の所定角度部位20aに固定されている。またバネ材4の両端側は、それぞれ外周面20(所定角度部位20a)に対して長手方向に摺動する自由端41,41とされている。したがって、保護管3内にバネ材4を設けたシース温度計2を挿着する際、バネ材4の湾曲形状部5,5は保護管内壁に押されて弾性復元力を溜めつつ潰されるように変形するが、各自由端41が外側に移動し、スムーズに前記変形を許容するのである。   The spring material 4 is composed of a bent wire, and as shown in FIG. 2, two curved portions 5 and 5 are connected in the longitudinal direction, and the sheath temperature between the curved portions 5 and 5 is A predetermined position (substantially central position) 40 that contacts the total outer peripheral surface 20 is fixed to a predetermined angle portion 20 a on the outer peripheral surface 20 of the sheath thermometer 2. The both ends of the spring material 4 are free ends 41 and 41 that slide in the longitudinal direction with respect to the outer peripheral surface 20 (predetermined angle portion 20a). Therefore, when the sheath thermometer 2 having the spring material 4 provided in the protective tube 3 is inserted, the curved portions 5 and 5 of the spring material 4 are pushed by the inner wall of the protective tube so as to be crushed while accumulating elastic restoring force. However, each free end 41 moves outward to allow the deformation smoothly.

また、バネ材4は、具体的にはステンレス等の金属線材を屈曲加工して構成されている。ここで、金属線材をとくに熱伝導の優れた金属材料とすれば、保護管内壁30bに直接圧接されるシース温度計外周面20の反対側部位20b以外に、保護管内壁30aに当接する湾曲形状部5,5を介してシース温度計2に熱伝達することができる点で好ましい。ただし、バネ材4の材料は変形により弾性復元力が生じるものであれば特に限定されず、金属材料以外の素材で構成することも可能である。また、バネ材4を線状で構成するもの以外に、例えば図4に示すように、板材で構成することも可能である。   The spring material 4 is specifically formed by bending a metal wire such as stainless steel. Here, if the metal wire is a metal material having particularly excellent heat conduction, a curved shape that contacts the protective tube inner wall 30a in addition to the portion 20b opposite to the outer surface 20b of the sheath thermometer that is directly pressed against the protective tube inner wall 30b. This is preferable in that heat can be transferred to the sheath thermometer 2 through the portions 5 and 5. However, the material of the spring material 4 is not particularly limited as long as an elastic restoring force is generated by deformation, and may be composed of a material other than a metal material. Further, in addition to the spring material 4 configured in a linear shape, for example, as illustrated in FIG. 4, it may be configured by a plate material.

このバネ材4は、シース温度計2の外周面20の所定角度部位20a上に長手方向に沿って設けられ、該バネ材4の湾曲形状部5が保護管内壁30aに当接することで、そのバネ材4の弾性復元力の反力によりシース温度計2の同じく外周面20の180°反対側の部位20bが保護管内壁30bに圧着されることとなる。バネ材4の外周面20(所定角度部位20a)上への取り付け方法は、本例では溶接等により固定しているが、それ以外に、例えばシース温度計外周面20上に係止用の突起を設け、該突起にバネ材4に設けた係合穴を係止させることでバネ材4を長手方向に移動不能に係合するように取り付けることも好ましい実施例である。同じく係合状態に取り付ける方法として、湾曲形状部5,5の内側の立ち上がり部分に係止される突起をそれぞれ設け、両方から挟み込むように係合することも好ましい。   The spring material 4 is provided along the longitudinal direction on a predetermined angle portion 20a of the outer peripheral surface 20 of the sheath thermometer 2, and the curved shape portion 5 of the spring material 4 abuts against the protective tube inner wall 30a, Due to the reaction force of the elastic restoring force of the spring material 4, the portion 20 b on the opposite side of the outer peripheral surface 20 of the sheath thermometer 2 is pressed against the inner wall 30 b of the protective tube. The method of attaching the spring material 4 onto the outer peripheral surface 20 (predetermined angle portion 20a) is fixed by welding or the like in this example. In addition to this, for example, a locking projection on the outer peripheral surface 20 of the sheath thermometer It is also a preferred embodiment to attach the spring material 4 so as to be immovably engaged in the longitudinal direction by locking the engaging hole provided in the spring material 4 to the protrusion. Similarly, as a method of attaching to the engaged state, it is also preferable to provide protrusions to be latched at the rising portions inside the curved shape portions 5 and 5 and engage so as to be sandwiched from both.

バネ材4の両端側の自由端41,41には、それぞれ略T字状に左右に膨出した摺動受け部6が設けられており、この摺動受け部6がシース温度計2の外周面20の所定角度部位20a上を長手方向に移動することで湾曲形状部5のスムーズな変形が可能となるとともに、その弾性復元力が安定してシース温度計2に作用することとなる。この変形容易性により保護管内への挿着操作が極めて容易となり、安定した弾性復元力の作用は保護管内壁30bへの良好な圧着を担保し、温度計測の優れた応答性を確実に発揮させるものである。   The free ends 41, 41 on both ends of the spring material 4 are provided with slide receiving portions 6 that bulge to the left and right in a substantially T shape, respectively, and this slide receiving portion 6 is the outer periphery of the sheath thermometer 2. The curved portion 5 can be smoothly deformed by moving in the longitudinal direction on the predetermined angle portion 20a of the surface 20, and the elastic restoring force stably acts on the sheath thermometer 2. Due to this ease of deformation, the insertion operation into the protective tube becomes extremely easy, and the action of the stable elastic restoring force ensures good pressure bonding to the protective tube inner wall 30b, and reliably exhibits excellent responsiveness of temperature measurement. Is.

この摺動受け部6は、本例ではバネ材4を構成している線材の両端側をそれぞれ左右に折り畳むように往復変形させて形成されているが、シース温度計外周面20の所定角度部位20a上から周方向にすべり落ちない受け機能を奏する形状であれば、例えば口形にしたりその他の形状に構成することも可能である。また、図5に示すように摺動受け部6を略Y字状に形成することが好ましい実施例である。T字状の摺動受け部6では、シース温度計2を保護管3へ挿入してシース温度計外周面20上をスライドさせる際、横ずれして保護管内壁に接触する場合があり、保護管内壁にギャップが生じていたり内壁の加工が粗いときには、このような接触によって摺動受け部6が保護管内壁に引っかかり破損する虞があるが、図5のように略Y字状に構成すれば、上記横ずれを防止して破損を未然に回避でき、シース温度計2の保護管3への挿入をスムーズに好適に行うことができる。特に、図5では外周面20を包み込むように曲線的な略Y字状に構成されており、外周面20上のよりスムーズなスライド移動を可能としている。   In this example, the sliding receiving portion 6 is formed by reciprocatingly deforming both ends of the wire constituting the spring material 4 so as to be folded left and right. As long as the shape has a receiving function that does not slide in the circumferential direction from the top of 20a, it can be formed into a mouth shape or other shapes, for example. Further, as shown in FIG. 5, it is a preferred embodiment that the sliding receiving portion 6 is formed in a substantially Y shape. In the T-shaped sliding receiving portion 6, when the sheath thermometer 2 is inserted into the protective tube 3 and slid on the outer surface 20 of the sheath thermometer, it may be laterally displaced and contact the inner wall of the protective tube. When there is a gap in the wall or when the inner wall is rough, the sliding receiving portion 6 may be caught by the inner wall of the protective tube due to such contact, but if it is configured in a substantially Y shape as shown in FIG. The lateral displacement can be prevented to prevent breakage, and the sheath thermometer 2 can be inserted into the protective tube 3 smoothly and suitably. In particular, in FIG. 5, it is configured in a curved substantially Y shape so as to wrap around the outer peripheral surface 20, thereby enabling a smoother sliding movement on the outer peripheral surface 20.

また、当該摺動受け部6を別途構成して溶接等で線材両端側に取り付けて構成しても勿論よい。また、上述したようにバネ材4を板材で構成する場合には、図4に示すように同じく略T字状に左右に膨出した形状としてもよいが、板材の幅によってはこのような膨出形状を構成せずに湾曲形状部5と同じ幅の端面を摺動受け部6として機能させることも可能となる。また、このようにバネ材4を板材で構成する場合においても、横ずれを防止するべく摺動受け部6を略Y字状に構成したり、少なくとも当接部分にシース熱電対2の外周面を一部受け入れる凹状部を設けておくことが好ましい。   Of course, the slide receiving portion 6 may be separately configured and attached to both ends of the wire by welding or the like. Further, when the spring material 4 is formed of a plate material as described above, it may have a substantially T-shaped bulge shape as shown in FIG. 4, but such a bulge may be formed depending on the width of the plate material. It is also possible to cause the end face having the same width as the curved shape portion 5 to function as the slide receiving portion 6 without configuring the protruding shape. Further, even when the spring material 4 is formed of a plate material in this way, the slide receiving portion 6 is configured in a substantially Y shape to prevent lateral displacement, or the outer peripheral surface of the sheath thermocouple 2 is provided at least at the contact portion. It is preferable to provide a concave portion to receive a part.

バネ材4の湾曲形状部5は、本例では二つ設けているが、三つ以上連設してもよい。この場合、本例と同様、何れかの湾曲形状部間の所定位置でシース温度計外周面20の所定角度部位20aに固定或いは係合させることが好ましい。また、図3に示すように、湾曲形状部5を一つ又は複数設けるとともに、自由端41と反対側の端部を固定端としてシース温度計外周面に固定又は係合させるように構成してもよい。図3のように湾曲形状部5を一つのみ設けたものでは生じる弾性復元力はシース温度計2の一部の範囲となるが、シース熱電対の場合など測温点が先端など一部に限定される場合はその測温点の部位を保護管内壁に圧接させるべく、このような一つのみの湾曲形状部5を位置させるように構成することも有効である。湾曲形状部5の数が少ないと保護管内への脱着の際の抵抗が小さくなり作業性が向上する。   Although two curved portions 5 of the spring material 4 are provided in this example, three or more curved portions 5 may be provided continuously. In this case, as in this example, it is preferable to fix or engage with the predetermined angle portion 20a of the outer surface 20 of the sheath thermometer at a predetermined position between any of the curved portions. Further, as shown in FIG. 3, one or a plurality of curved portions 5 are provided, and the end opposite to the free end 41 is used as a fixed end to be fixed or engaged with the outer surface of the sheath thermometer. Also good. As shown in FIG. 3, the elastic restoring force generated in the case where only one curved shape portion 5 is provided is in a part of the range of the sheath thermometer 2, but the temperature measuring point is partly in the tip, such as in the case of a sheath thermocouple. In a limited case, it is also effective to configure such that only one curved shape portion 5 is positioned so that the temperature measuring point is pressed against the inner wall of the protective tube. When the number of the curved portions 5 is small, the resistance at the time of attachment to and removal from the protective tube is reduced and workability is improved.

シース温度計2の外周面20へのバネ材4の取り付けは、以上の説明のように固定或いは係合により支持する方法以外に、例えばバネ材4の全体が所定距離だけ長手方向に自由に移動できるように拘束して取り付けることも可能である。例えば、シース温度計2の外周面20上に長手方向に所定距離離してバネ材4を当止させる一対の突起を設け、これら突起間を移動できるようにバネ材4を取り付けるようにしてもよい。また、図4に示すようにバネ材4が板材から構成される場合には、該バネ材4に長穴を設け、これに係合する突起を外周面20上に設けて長穴の長さだけバネ材4が移動できるように構成したものでもよい。   The attachment of the spring material 4 to the outer peripheral surface 20 of the sheath thermometer 2 is not limited to the method of supporting it by fixing or engaging as described above. For example, the entire spring material 4 is freely moved in the longitudinal direction by a predetermined distance. It is also possible to restrain and attach as possible. For example, a pair of protrusions for stopping the spring material 4 at a predetermined distance in the longitudinal direction may be provided on the outer peripheral surface 20 of the sheath thermometer 2 and the spring material 4 may be attached so as to be able to move between these protrusions. . In addition, when the spring material 4 is made of a plate material as shown in FIG. 4, a long hole is provided in the spring material 4, and a protrusion that engages with the long hole is provided on the outer peripheral surface 20 to thereby determine the length of the long hole. It may be configured such that only the spring material 4 can move.

以上、本実施形態ではシース温度計2の外周面20上にバネ材4を1つのみ設けた例について説明したが、シース温度計2や保護管3の長さ、用途、種類に応じて、長手方向に複数のバネ材を連設するようにしてシース温度計2のより長い任意の範囲を保護管内壁に圧着させるようにすることも好ましい例である。   As described above, in the present embodiment, the example in which only one spring material 4 is provided on the outer peripheral surface 20 of the sheath thermometer 2 has been described, but depending on the length, application, and type of the sheath thermometer 2 and the protective tube 3, It is also a preferable example that a plurality of spring materials are continuously arranged in the longitudinal direction so that an arbitrary longer range of the sheath thermometer 2 is crimped to the inner wall of the protective tube.

また、以上の例ではバネ材4として、湾曲形状部5の一端側をシース温度計2の外周面所定角度部位20aに固定し、他端側の自由端41を外周面20(所定角度部位20a)に対して長手方向に摺動するように構成したが、その他の例として、例えば図6に示すように、一端側の所定位置40を同じくシース温度計2の外周面所定角度部位20aに固定するとともに、当該固定された部位から略V字状ないし略C字状に折り返して斜め上方に延びる湾曲形状部5を構成し、その端部が上下方向に自由に移動する自由端41としたものも好ましい。図中(a)ではこのようなバネ材4を複数設けた例、図中(b)では比較的長いバネ材4を一つ設けた例を示しており、いずれも先端側から基端側に折り返した湾曲形状部5を設けているが、中央部を固定し、両端側にそれぞれ先端側から基端側に折り返したものと基端側から先端側に折り返したものとよりなる一対の湾曲形状部を設けたものも勿論可能である。   In the above example, as the spring material 4, one end of the curved portion 5 is fixed to the outer peripheral surface predetermined angle portion 20a of the sheath thermometer 2, and the free end 41 on the other end side is fixed to the outer peripheral surface 20 (predetermined angle portion 20a). However, as another example, for example, as shown in FIG. 6, a predetermined position 40 on one end side is fixed to the outer peripheral surface predetermined angle portion 20a of the sheath thermometer 2 as well. In addition, a curved portion 5 is formed that folds back from the fixed portion into a substantially V shape or C shape and extends obliquely upward, and the end portion is a free end 41 that freely moves in the vertical direction. Is also preferable. In the figure, (a) shows an example in which a plurality of such spring materials 4 are provided, and (b) in the figure shows an example in which one relatively long spring material 4 is provided, both from the distal end side to the proximal end side. A folded curved portion 5 is provided, but the central portion is fixed, and a pair of curved shapes each consisting of a folded portion from the distal end side to the proximal end side and a folded portion from the proximal end side to the distal end side at both ends. Of course, it is possible to provide a part.

また、さらに他の例として、例えば図7に示すように、バネ材4を環状または両端が固定される略C字状に形成することも可能である。図中(a)は環状に構成したもの、図中(b)は略C字状に構成したものを例示しており、何れも湾曲形状部5は中央位置が山形に屈曲した略五角形の形状とされているが、保護管内壁30aに当接して全体が変形しやすい形状であれば、その他の形状、例えば曲げ部分のRを小さくして菱形に近い形状にしたり、逆に緩やかにカーブする長円形状にすることも好ましい。尚、上記図6、7に示す例においても、バネ材4は丸棒等の線状で構成するもの以外に平板等の板材で構成することも勿論可能である。   As still another example, as shown in FIG. 7, for example, the spring material 4 can be formed in an annular shape or a substantially C shape in which both ends are fixed. In the figure, (a) illustrates an annular configuration, and (b) illustrates an approximately C-shaped configuration, and in both cases, the curved portion 5 has a substantially pentagonal shape with a central position bent in a mountain shape. However, as long as the shape is in contact with the inner wall 30a of the protective tube and is easily deformed, other shapes, for example, the bent portion R is reduced to a shape close to a rhombus, or conversely gently curved. An oval shape is also preferable. In the examples shown in FIGS. 6 and 7, the spring material 4 can of course be constituted by a plate material such as a flat plate in addition to the wire material such as a round bar.

また、上記実施形態においては押圧部材としてバネ材を利用した場合について説明したが、これに限定されず、例えば押圧部材として、スポンジ状の樹脂片や、ゴム片等を利用しても良い。なお、これらの押圧部材を利用する場合も、シース温度計の任意の部位と保護管が直接接触するように配置し、押圧部材が接触部分に介在しないようにすることが好ましい。   Moreover, although the case where a spring material is used as the pressing member has been described in the above embodiment, the present invention is not limited thereto, and for example, a sponge-like resin piece, a rubber piece, or the like may be used as the pressing member. Even when these pressing members are used, it is preferable that an arbitrary part of the sheath thermometer and the protective tube are arranged so as to be in direct contact so that the pressing member is not interposed in the contact portion.

次に、図8に基づき本発明の第2実施形態を説明する。   Next, a second embodiment of the present invention will be described based on FIG.

本実施形態では、図8(a)に示すように、バネ材4の湾曲形状部5を挟んだ一端側の所定位置40がシース温度計2外周面20上の所定角度部位20aに固定されるとともに、他端側がシース温度計2の先端部21よりも先端側に延出した自由端41とされている。そして、保護管3内にバネ材4を設けたシース温度計2を挿着する際、図8(b)に示すようにバネ材4の延出した他端側の自由端41が保護管3の底壁30cに当接することで、該自由端41からバネ材4が縮まる方向に押され、図8(c)に示すように当該バネ材4の湾曲形状部5が保護管内壁30a側に更に突き出るように屈曲して頂部が当接してさらに変形し、当該変形したバネ材4の弾性復元力の反力によりシース温度計2の同じく外周面20の180°反対側の部位20bが保護管内壁30bに圧接されることとなる。   In the present embodiment, as shown in FIG. 8A, a predetermined position 40 on one end side of the curved portion 5 of the spring material 4 is fixed to a predetermined angle portion 20 a on the outer peripheral surface 20 of the sheath thermometer 2. At the same time, the other end is a free end 41 extending from the distal end portion 21 of the sheath thermometer 2 to the distal end side. When the sheath thermometer 2 provided with the spring material 4 is inserted into the protective tube 3, the free end 41 on the other end side where the spring material 4 extends is the protective tube 3 as shown in FIG. 8b, the spring material 4 is pushed from the free end 41 in the direction of contraction, and the curved portion 5 of the spring material 4 moves toward the protective tube inner wall 30a as shown in FIG. 8C. Furthermore, the portion 20b on the opposite side of the outer peripheral surface 20 of the sheath thermometer 2 is 180 ° away from the inside of the protective tube by the reaction force of the elastic restoring force of the deformed spring material 4 by bending so as to protrude further. It will be pressed against the wall 30b.

このような構成によれば、バネ材4の他端側の自由端41が保護管底壁30cに当接して湾曲形状部5が湾曲して保護管内壁30aに当接させるものであるから、変形前のバネ材2と保護管内壁30aとの間に隙間を有する寸法に設定することができ、シース温度計2の装着作業をよりスムーズに行うことが可能となるのである。バネ材4は線材でも板材でもよく、素材その他の変形例等についても上記第1実施形態と同じであるので、その説明は省略する。尚、本例では湾曲形状部5を固定される位置40と自由端41との間に一つのみ設けているが、これに限らず二つ以上連設したものでもよい。   According to such a configuration, the free end 41 on the other end side of the spring material 4 is in contact with the protective tube bottom wall 30c, and the curved portion 5 is bent to be in contact with the protective tube inner wall 30a. It is possible to set a dimension having a gap between the spring material 2 before deformation and the inner wall 30a of the protective tube, and it is possible to perform the mounting operation of the sheath thermometer 2 more smoothly. The spring material 4 may be a wire material or a plate material, and the material and other modified examples are the same as those in the first embodiment, and the description thereof will be omitted. In this example, only one curved portion 5 is provided between the fixed position 40 and the free end 41. However, the present invention is not limited to this, and two or more curved portions may be provided continuously.

以上、本発明の実施形態について説明したが、本発明はこうした実施例に何ら限定されるものではなく、本発明の要旨を逸脱しない範囲において種々なる形態で実施し得ることは勿論である。   Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention.

次に、本発明に係る実施例1と他の構造の比較例1〜4について、応答速度を試験した結果について説明する。尚、何れもシース温度計はシース測温抵抗体とした。   Next, the results of testing the response speed of Example 1 according to the present invention and Comparative Examples 1 to 4 having other structures will be described. In all cases, the sheath thermometer was a sheath resistance thermometer.

実施例1は図1に示した構造のものであり、比較例1は、図5(a)に示すようにストレートのシース温度計102をストレートの保護管103内に隙間を介して挿着した従来からの通常の構造である。比較例2は、図5(b)に示すようにシース温度計102の先端をリング状に屈曲形成し、該先端のリング部を保護管先端の内壁103a(底壁)に押し付けた構造のものである。比較例3は、図5(c)に示すように保護管103先端の縮径部分103bを熱伝導に優れたタンタルで構成し、その縮径部分103bに微小隙間を介してシース温度計102の先端側を内装したものであり、上述した特許文献3に相当するものである。比較例4は、図5(d)に示すようにシース温度計102の外周面に薄板状のフィン107を取り付け、これを保護管103内壁に沿わせるようにし、該フィン107を介して保護管からシース温度計に熱伝導させる構造のものである。   Example 1 has the structure shown in FIG. 1, and Comparative Example 1 has a straight sheath thermometer 102 inserted into a straight protective tube 103 through a gap as shown in FIG. 5A. It is a conventional normal structure. Comparative Example 2 has a structure in which the tip of the sheath thermometer 102 is bent in a ring shape as shown in FIG. 5B, and the ring portion at the tip is pressed against the inner wall 103a (bottom wall) at the tip of the protective tube. It is. In Comparative Example 3, as shown in FIG. 5C, the diameter-reduced portion 103b at the tip of the protective tube 103 is made of tantalum having excellent heat conduction, and the diameter-reduced portion 103b of the sheath thermometer 102 is interposed through a minute gap. The front end side is built in and corresponds to the above-mentioned Patent Document 3. In Comparative Example 4, as shown in FIG. 5 (d), a thin plate-like fin 107 is attached to the outer peripheral surface of the sheath thermometer 102 so as to be along the inner wall of the protective tube 103, and the protective tube is interposed via the fin 107. It is a structure which conducts heat to a sheath thermometer.

試験は、92℃温水循環槽へ実施例1、比較例1〜4の各温度測定器を瞬時に挿入し、測温抵抗体の温度上昇を時間(秒)で計測した。結果を下記表1に示す。   In the test, each temperature measuring device of Example 1 and Comparative Examples 1 to 4 was instantaneously inserted into a 92 ° C. hot water circulation tank, and the temperature rise of the resistance temperature detector was measured in time (seconds). The results are shown in Table 1 below.

Figure 0005188310
Figure 0005188310

表1から分かるように、本発明の実施例1では、63.20%まで30秒ほど、90%まで1分程度で達しており、充分な応答速度を備えていることが分かる。これに対し、比較例1は、63.20%まで上昇するのに4分近く、90%まで上昇するのに8分以上かかっており、かなり遅れている。これはシース測温抵抗体の測温部分が直接保護管内壁に接することがなく、空気層の存在により側面部からの伝熱も時間がかかり応答速度が悪いためである。   As can be seen from Table 1, in Example 1 of the present invention, 63.20% is reached in about 30 seconds and 90% is reached in about 1 minute. On the other hand, in Comparative Example 1, it took nearly 4 minutes to increase to 63.20% and took more than 8 minutes to increase to 90%, which is a considerable delay. This is because the temperature measuring part of the sheath resistance thermometer does not directly contact the inner wall of the protective tube, and due to the presence of the air layer, heat transfer from the side surface takes time and the response speed is poor.

比較例4はフィンを介して接触したものであるが、間接的な伝熱であるが故に応答速度の向上効果も僅かであったと予測できる。比較例2は直接接触しており比較例1、4よりも応答性は向上しているが、90%まで2分以上経過しており充分ではない。これはシース測温抵抗体が保護管底面でのみ接するため、測温部分までの伝熱時間がかかるためと予測できる。比較例3は他の比較例の中では最も応答性が良かったが、それでも90%まで2分近く要している。   Although the comparative example 4 was contacted via the fin, it can be predicted that the effect of improving the response speed was slight because of indirect heat transfer. Comparative Example 2 is in direct contact and has improved responsiveness compared to Comparative Examples 1 and 4, but it is not sufficient since 90 minutes and 2 minutes have passed. This is because the sheath resistance thermometer is in contact only with the bottom surface of the protective tube, and it can be predicted that heat transfer time to the temperature measuring portion is required. Although the comparative example 3 was the most responsive among the other comparative examples, it still takes nearly 2 minutes to 90%.

以上の結果より、測温部分であるシース外周面を直接保護管内壁に圧接させている本発明は、応答性が極めて優れていることが分かる。尚、比較例3の先端部分は他の部分と異なる材質(タンタル)により構成して螺合等により組み付けたものであるが、このような組み付け部は被処理物のコンタミ(汚染)の原因となるとともに該先端部が腐食する原因ともなるが、本発明ではこのような先端部分やその組み付け部が存在せずに、通常のストレート保護管の内部にシース温度計をバネ材とともに内装して容易に構成できるため、被処理物のコンタミや腐食等の虞もない。   From the above results, it can be seen that the present invention in which the outer peripheral surface of the sheath, which is a temperature measuring portion, is directly pressed against the inner wall of the protective tube is extremely excellent in responsiveness. The tip portion of Comparative Example 3 is made of a material (tantalum) different from that of the other portions and assembled by screwing or the like. Such an assembled portion causes contamination (contamination) of the object to be processed. However, in the present invention, there is no such tip portion or its assembly portion, and a sheath thermometer is easily installed with a spring material inside a normal straight protective tube. Therefore, there is no risk of contamination or corrosion of the object to be processed.
