Description

本願は、温度測定装置及びそれを用いた温度測定方法に関する。   The present application relates to a temperature measurement device and a temperature measurement method using the same.

工場やプラントにおいては、各種のトラップや配管が数多く取り付けられており、これらのトラップや配管は、温度測定装置を用いて、絶えず又は定期的にその温度状態がチェックされている。   Many kinds of traps and pipes are installed in factories and plants, and these traps and pipes are constantly or periodically checked for temperature using a temperature measuring device.

従来の温度測定装置は、ケーシングとの間に配置したコイルばねで検出針の先端をケーシングよりも突出せしめ、検出針の外周に断熱部材を配置し、検出針の先端が入る孔を中心に開けた温度センサを断熱部材の上面に載せて配置し、ケーシングと断熱部材の間にコイルばねを配置して温度センサの先端をケーシングよりも突出せしめたものである（例えば特許文献１参照。）。このような温度測定装置によれば、温度センサの中心に開けた孔から検出針の先端をケーシングの先端まで押し込んだ位置で被測定物（例えばトラップや配管）の振動を検出できるとともに、上記温度センサにより被測定物の温度も同時に検出することができる。   Conventional temperature measuring devices use a coil spring placed between the casing and the tip of the detection needle to protrude from the casing. A heat insulating member is placed on the outer periphery of the detection needle, and a hole is inserted around the hole into which the tip of the detection needle enters. The temperature sensor is placed on the upper surface of the heat insulating member, and a coil spring is disposed between the casing and the heat insulating member so that the tip of the temperature sensor protrudes beyond the casing (see, for example, Patent Document 1). According to such a temperature measuring device, it is possible to detect the vibration of an object to be measured (for example, a trap or a pipe) at a position where the tip of the detection needle is pushed into the tip of the casing from the hole opened in the center of the temperature sensor, and the temperature The sensor can also detect the temperature of the object to be measured at the same time.

しかしながら、上記温度測定装置は被測定物表面の測定箇所に直接押し当てるものであるため、作業者により、温度測定装置の押し当て精度が異なり、表面温度の測定結果にバラツキが生じ、測定作業に熟練を要する。そのため、作業者の温度測定装置の押し当て精度が悪いと、正確な温度測定が困難となる。   However, since the above temperature measuring device directly presses against the measurement location on the surface of the object to be measured, the pressing accuracy of the temperature measuring device varies depending on the operator, and the measurement result of the surface temperature varies. Requires skill. Therefore, if the pressing accuracy of the temperature measuring device of the operator is poor, accurate temperature measurement becomes difficult.

本願は、このような事情に鑑みなされたもので、表面温度の測定精度に優れた温度測定装置及び温度測定方法の提供を目的とする。   The present application has been made in view of such circumstances, and an object thereof is to provide a temperature measuring device and a temperature measuring method excellent in surface temperature measurement accuracy.

上記の課題を解決するために、本願に開示する温度測定装置は、熱接点を有する第一部材と、冷接点に接続する熱電対線を有し、前記第一部材と嵌合する第二部材とを備えた温度測定装置であって、前記熱接点は、温度測定対象物に形成されており、前記熱電対線は、前記第一部材と前記第二部材とが嵌合した場合に、前記熱接点と導通する。   In order to solve the above problems, a temperature measuring device disclosed in the present application includes a first member having a hot junction, and a second member having a thermocouple wire connected to the cold junction and fitting with the first member. The thermal contact is formed on a temperature measurement object, and the thermocouple wire is inserted when the first member and the second member are engaged with each other. Conducts with thermal contact.

また、本願に開示する温度測定方法は、熱接点を有する第一部材と、冷接点に接続する熱電対線を有し、前記第一部材と嵌合する第二部材とを備えた温度測定装置を用いた温度測定方法であって、前記熱接点は、温度測定対象物に形成されており、前記第一部材と前記第二部材とを嵌合することにより、前記熱電対線と熱接点とを導通させる。   Moreover, the temperature measuring method disclosed in the present application includes a first member having a hot junction, and a second member that has a thermocouple wire connected to the cold junction and is fitted to the first member. The thermal contact is formed on a temperature measurement object, and the thermocouple wire and the thermal contact are formed by fitting the first member and the second member. Is made conductive.

本願に開示する温度測定装置又は温度測定方法によれば、温度測定装置を構成する第一部材の熱接点は、温度測定対象物（例えばトラップ）に形成されているため、作業者は、第一部材と前記第二部材とを嵌合させることにより、簡単に温度測定対象物の表面温度を測定することができる。そのため、温度測定装置の押し当て精度の違いによる測定結果のバラツキが生じ難くなり、温度測定対象物の表面温度を正確に測定できるようになる。   According to the temperature measuring device or the temperature measuring method disclosed in the present application, since the thermal contact of the first member constituting the temperature measuring device is formed on the temperature measuring object (for example, a trap), By fitting the member and the second member, the surface temperature of the temperature measurement object can be easily measured. Therefore, variations in measurement results due to differences in pressing accuracy of the temperature measuring device are less likely to occur, and the surface temperature of the temperature measurement object can be accurately measured.

各第二端子部１２の先端の左右面にはやすり状のやすり面１２ａがそれぞれ形成され、やすり面１２ａの上側（図１の紙面上側）に、第一端子部２１と導通する導通部１２ｂが形成される。各第二端子部１２は、保持部材１３の通路１３ａに挿通され長手方向に摺動可能となっている。第二端子部１２の他端１２ｃには、熱電対線１１（例えば、アルメル線１１ａ及びクロメル線１１ｂ）が溶接等により接合され、熱電対線１１は冷接点１８に接続されている。   A file-shaped file surface 12a is formed on each of the left and right surfaces of the tip of each second terminal portion 12, and a conductive portion 12b that is electrically connected to the first terminal portion 21 is provided above the file surface 12a (upper side of the drawing in FIG. 1). It is formed. Each second terminal portion 12 is inserted into the passage 13a of the holding member 13 and is slidable in the longitudinal direction.

図２に図１のＸ部の拡大図を示す。なお、図１において、第二端子部１２は断面図として示していない。第二端子部１２のやすり面１２ａの上側（図１の紙面上側）の左右面には、第一部材２０と第二部材１０とが嵌合する際に、保持部材１３の外部に露出して第一部材２０の第一端子部２１と導通する導通部１２ｂが形成される。保持部材１３は、導通部１２ｂを接触保持する。保持部材１３の通路１３ａの内周面には、第二端子部１２の導通部１２ｂが摺動することにより導通部１２ｂを研磨するやすり面１３ｂが形成される。   FIG. 2 shows an enlarged view of a portion X in FIG. In addition, in FIG. 1, the 2nd terminal part 12 is not shown as sectional drawing. When the first member 20 and the second member 10 are fitted to the left and right surfaces above the file surface 12a of the second terminal portion 12 (upper side in FIG. 1), they are exposed to the outside of the holding member 13. A conductive portion 12b that is electrically connected to the first terminal portion 21 of the first member 20 is formed. The holding member 13 holds the conductive portion 12b in contact. On the inner peripheral surface of the passage 13a of the holding member 13, a file surface 13b for polishing the conductive portion 12b is formed by sliding the conductive portion 12b of the second terminal portion 12.

次に、本実施形態の温度測定装置を用いた温度測定方法について、図１〜図３を参照しながら説明する。図３は第一部材２０と第二部材１０とを嵌合させた状態を示す断面図である。なお、図１と同様に、図３において、トラップ１は温度測定の対象位置となる付近のみを示し、トラップ１、第一部材２０及び第二部材１０の一部は断面図として示していない。   Next, a temperature measurement method using the temperature measurement device of the present embodiment will be described with reference to FIGS. FIG. 3 is a cross-sectional view showing a state in which the first member 20 and the second member 10 are fitted. As in FIG. 1, in FIG. 3, the trap 1 shows only the vicinity of the target position for temperature measurement, and the trap 1, the first member 20, and a part of the second member 10 are not shown as sectional views.

第二部材１０をトラップ１の表面１ａに取り付けた第一部材２０側に差し込み、第二部材１０と第一部材２０とを嵌合させると、保持部材１３の押し込みは、保持部材１３の下部１３ｄがストッパー２６の上部２６ｕと当接した位置でストップし、その後の差し込み力により保持部材１３を付勢するコイルばね１４が圧縮する。コイルばね１４の圧縮により、各第二端子部１２の導通部１２ｂは、保持部材１３のやすり面１３ｂ（図２参照）を摺動して保持部材１３の外部に露出する。このとき、第二端子部１２の導通部１２ｂの表面は、保持部材１３のやすり面１３ｂとの接触により研磨される。一方、第二端子部１２の先端面のやすり面１２ａは、第一端子部２１の底面２１ｂに向けて押し込まれ、第一端子部２１のコンタクト部２４の表面は、第二端子部１２のやすり面１２ａの摺動により研磨される。   When the second member 10 is inserted into the first member 20 side attached to the surface 1 a of the trap 1 and the second member 10 and the first member 20 are fitted, the pushing of the holding member 13 is performed at the lower portion 13 d of the holding member 13. Is stopped at a position where it comes into contact with the upper portion 26u of the stopper 26, and the coil spring 14 that urges the holding member 13 is compressed by the subsequent insertion force. Due to the compression of the coil spring 14, the conducting portion 12 b of each second terminal portion 12 slides on the file surface 13 b (see FIG. 2) of the holding member 13 and is exposed to the outside of the holding member 13. At this time, the surface of the conductive portion 12 b of the second terminal portion 12 is polished by contact with the file surface 13 b of the holding member 13. On the other hand, the file surface 12a of the tip surface of the second terminal portion 12 is pushed toward the bottom surface 21b of the first terminal portion 21, and the surface of the contact portion 24 of the first terminal portion 21 is the file of the second terminal portion 12. It is polished by sliding the surface 12a.

やがて、第二端子部１２の先端が第一端子部２１の底面２１ｂに突き当たると、第二端子部１２の導通部１２ｂは、第一端子部２１のコンタクト部２４と導通する位置で摺動を停止する。これにより、第二部材１０の熱電対線１１は、第二端子部１２を介して、第一部材２０の熱電対線２２及び熱接点２３と導通する。各熱電対線（例えば、アルメル線及びクロメル線）によって生じた電位差及び冷接点１８に基づいて、上述した熱電対回路を有する装置は、トラップ１に形成された熱接点２３の温度を検出する。   Eventually, when the tip of the second terminal portion 12 abuts against the bottom surface 21 b of the first terminal portion 21, the conducting portion 12 b of the second terminal portion 12 slides at a position where it conducts with the contact portion 24 of the first terminal portion 21. Stop. Thereby, the thermocouple wire 11 of the second member 10 is electrically connected to the thermocouple wire 22 and the thermal contact 23 of the first member 20 via the second terminal portion 12. Based on the potential difference generated by each thermocouple wire (for example, an alumel wire and a chromel wire) and the cold junction 18, the device having the thermocouple circuit described above detects the temperature of the hot junction 23 formed in the trap 1.

以上のように、本実施形態の温度測定装置を構成する第一部材２０の熱接点２３は、トラップ１に形成されているため、作業者は、第一部材２０と第二部材１０とを嵌合させることにより、簡単にトラップ１の表面温度を測定することができる。そのため、温度測定装置の押し当て精度の違いによる測定結果のバラツキが生じ難くなり、トラップ１の表面温度を正確に測定できるようになる。   As described above, since the thermal contact 23 of the first member 20 constituting the temperature measuring device of the present embodiment is formed on the trap 1, the operator fits the first member 20 and the second member 10 together. By combining, the surface temperature of the trap 1 can be easily measured. Therefore, variations in measurement results due to the difference in pressing accuracy of the temperature measuring device are less likely to occur, and the surface temperature of the trap 1 can be accurately measured.

また、本実施形態によれば、第二端子部１２の先端の左右面にやすり面１２ａがそれぞれ形成され、保持部材１３の通路１３ａの内周面にもやすり面１３ｂが形成されているため、コンタクト部２４の表面や第二端子部１２の導通部１２ｂの表面にサビ、塵、埃等の付着物がある場合でも、やすり面１２ａもしくはやすり面１３ｂとの接点を研磨して、上記のような付着物を除去することができる。これにより、第二部材１０の熱電対線１１と、第一部材２０の熱接点２３との導通が良好となり、トラップ１の表面温度を正確に測定することができる。   Further, according to the present embodiment, the file surface 12a is formed on the left and right surfaces of the tip of the second terminal portion 12, respectively, and the file surface 13b is also formed on the inner peripheral surface of the passage 13a of the holding member 13, Even when there is rust, dust, dust or other deposits on the surface of the contact portion 24 or the surface of the conducting portion 12b of the second terminal portion 12, the contact with the file surface 12a or the file surface 13b is polished as described above. Extraneous matter can be removed. Thereby, the electrical connection between the thermocouple wire 11 of the second member 10 and the hot contact 23 of the first member 20 becomes good, and the surface temperature of the trap 1 can be accurately measured.

なお、上記実施形態においては、第一部材２０や第二部材１０の各構成部材として図１に示したものを使用したが、本願の温度測定装置はこれらに限定されるものではない。上記実施形態では、第二端子部１２を平板状としたが、形状は特に限定はなく棒状とすることもできる。また、上記実施形態では、熱電対線１１，２２としてアルメル線及びクロメル線を例示したが、他の熱電対線にも適用することができる。   In addition, in the said embodiment, what was shown in FIG. 1 was used as each structural member of the 1st member 20 and the 2nd member 10, However, The temperature measurement apparatus of this application is not limited to these. In the said embodiment, although the 2nd terminal part 12 was made into flat form, shape does not have limitation in particular and can also be made into rod shape. Moreover, in the said embodiment, although the alumel wire and the chromel wire were illustrated as the thermocouple wires 11 and 22, it can be applied to other thermocouple wires.

また、上記実施形態では、温度測定対象物としてトラップに適用した例を示したが、配管に適用できる他、電化製品等のあらゆる温度測定対象物にも適用することができる。なお、温度測定対象物の表面に第一部材の熱接点を直接形成しにくい場合等には、温度測定対象物の表面に平坦な測定座を設け、該測定座に第一部材の熱接点を形成することもできる。   Moreover, in the said embodiment, although the example applied to the trap as a temperature measurement object was shown, besides being applicable to piping, it is applicable also to all temperature measurement objects, such as an electrical appliance. If it is difficult to directly form the thermal contact of the first member on the surface of the temperature measurement object, a flat measurement seat is provided on the surface of the temperature measurement object, and the thermal contact of the first member is provided on the measurement seat. It can also be formed.

本願は、温度測定対象物（例えばトラップ）の温度測定装置に適用することができる。   The present application can be applied to a temperature measurement device for a temperature measurement object (for example, a trap).
