特開２０００−１２１４２５号公報Japanese Patent Laid-Open No. 2000-121425

上記従来技術の弁類の作動状態検出装置は、弁類の被検出部に作動状態検出用のセンサを当接させて取り付けるときに、作動状態検出用のセンサがＵボルト及びナットと共に回転したりずれたりするために、取り付けが困難であるという問題点があった。 In the above-described prior art valve operation state detection device, when the operation state detection sensor is attached to the detected portion of the valve, the operation state detection sensor rotates together with the U bolt and nut. There is a problem that it is difficult to mount due to displacement.

従って、本発明の技術的課題は、被検出部に作動状態検出用のセンサを簡単に取り付けることができる弁類の作動状態検出装置を提供することである。 Therefore, the technical problem of the present invention is to provide an operating state detecting device for valves, which can easily attach an operating state detecting sensor to a detected portion.

上記の技術的課題を解決するために講じた本発明の技術的手段は、被検出部に当接される作動状態検出用のセンサと、作動状態検出用のセンサが連結されると共に一対の挿入孔が設けられ被検出部の片面に位置する保持部材と、被検出部の反対面に位置し上壁と両側壁を有する断面概略コ字状で上壁に一対の挿入孔が設けられると共に一対の挿入孔の間に被検出部の角柱の平面部に当接する平面部が形成され両側壁に被検出部の丸柱の曲面部の両側に当接する断面概略く字状溝部が形成された挟持部材と、挟持部材の一対の挿入孔及び保持部材の一対の挿入孔に両脚部が挿入されるＵボルトと、Ｕボルトの両脚部に取り付けられる一対のナットと、を具備することを特徴とする弁類の作動状態検出装置にある。 The technical means of the present invention taken in order to solve the above technical problem is that an operating state detection sensor abutted on a detected part and an operating state detection sensor are connected and a pair of insertions are made. A holding member which is provided with a hole and is located on one side of the detected part, and a pair of insertion holes provided on the upper wall with a substantially U-shaped cross section having an upper wall and both side walls located on the opposite side of the detected part and a pair A sandwiching member in which a planar portion that abuts against a planar portion of a rectangular column of the detected portion is formed between the insertion holes of the two, and a substantially cross-section groove portion that abuts on both sides of the curved portion of the round column of the detected portion is formed on both side walls And a pair of insertion holes of the clamping member and a pair of insertion holes of the holding member, a U-bolt into which both legs are inserted, and a pair of nuts attached to both the legs of the U-bolt. It is in a kind of operating state detection device.

本発明の弁類の作動状態検出装置は、挟持部材が被検出部の反対面に位置し上壁と両側壁を有する断面概略コ字状で上壁に一対の挿入孔が設けられると共に一対の挿入孔の間に被検出部の角柱の平面部に当接する平面部が形成され両側壁に被検出部の丸柱の曲面部の両側に当接する断面概略く字状溝が形成されたものであり、被検出部と挟持部材の接触面積を大きくできるので、作動状態検出用のセンサがＵボルト及びナットと共に回転したりずれたりすることを防止でき、被検出部に作動状態検出用のセンサを簡単に取り付けることができるという優れた効果を生じる。 The operation state detecting device for valves according to the present invention includes a pair of insertion holes provided in the upper wall and a pair of insertion holes provided in the upper wall with a sandwiching member positioned on the opposite surface of the detected portion and having an upper wall and both side walls. Between the insertion holes, a flat portion that contacts the flat portion of the prism of the detected portion is formed, and a substantially cross-sectional groove that contacts both sides of the curved portion of the round column of the detected portion is formed on both side walls. Since the contact area between the detected part and the clamping member can be increased, the sensor for detecting the operating state can be prevented from rotating or shifting with the U-bolt and nut, and the sensor for detecting the operating state can be easily applied to the detected part. This produces an excellent effect that it can be attached to.
