Description

本考案は、回転補償器の技術分野に関し、具体的には、特に長距離工業蒸気パイプラインの回転補償器の補償量指示装置に関する。 TECHNICAL FIELD The present invention relates to the technical field of rotation compensators, and more particularly to a compensation amount indicating device for rotation compensators of long-distance industrial steam pipelines.

回転補償器は、長距離工業蒸気パイプラインの設計、取り付けにおいて、長距離パイプの熱膨張と冷収縮によるパイプの長さの変化を補償する装置として、広く用いられている。実際の工業蒸気パイプラインの運転中で、設計蒸気流量と実際蒸気流量、設計蒸気パラメーターと実際蒸気パラメーターとの間に必然的に差異が存在するため、あるいは設計の考慮が足りない、あるいは取り付けが設計基准に達していない、あるいは補償器が要求に応じて取り付けられていないなどの原因で、回転補償器は長期にわたって過補償状態となり、その結果、補償器の漏れが発生し、財産損失及び人身傷害をもたらすことになる。 Rotating compensators are widely used in the design and installation of long-distance industrial steam pipelines as a device to compensate for changes in pipe length due to thermal expansion and cold contraction of long-distance pipes. During the operation of the actual industrial steam pipeline, there will inevitably exist differences between the design steam flow rate and the actual steam flow rate, the design steam parameters and the actual steam parameters, or the design consideration is insufficient, or the installation is improper. Due to not being up to design standards or the compensator not being installed as required, the rotary compensator will be overcompensated for a long period of time, resulting in compensator leakage, property loss and personal injury. will result in injury.

現在一般的に使用されている回転補償器は、使用開始した後、補償量をはっきりと見て判断することができなく、補償器の不良状態を早期に発見し、早期に対処することができず、回転補償器の補償量に対する監視検査も目視検査だけで回転補償器の変化を監視して、直感的で効果的な監視手段を欠いており、また人によってその監視位置、補償量に対する認識が異なり、補償量の変化に対する見方も異なるため、効果的な早期警報方法が欠けている。 With the rotation compensator currently in general use, it is not possible to clearly see and judge the amount of compensation after the start of use. In addition, the monitoring inspection for the compensation amount of the rotation compensator is only a visual inspection to monitor changes in the rotation compensator, lacking intuitive and effective monitoring means, and human recognition of the monitoring position and compensation amount. different perspectives on changes in compensation amounts, there is a lack of an effective early warning method.

本考案は、従来の回転補償器が、使用開始した後、補償量をはっきりと見て判断することができず、回転補償器の補償量に対する監視検査も目視検査だけで回転補償器の変化を監視して、効果的な早期警報方法が欠けているという問題点に鑑みてなされたものであり、長距離工業蒸気パイプラインの回転補償器の補償量指示装置を提供する。該装置は、回転筒体に指針を取り付け、同心レジューサーに目盛りとタッチスイッチ付きの文字盤を設置することにより、自動の早期警報を実現することができる。 The compensation amount of the conventional rotation compensator cannot be clearly seen and judged after the start of use, and the monitoring inspection of the compensation amount of the rotation compensator is only a visual inspection to detect the change of the rotation compensator. SUMMARY OF THE INVENTION The problem of the lack of an effective early warning method for monitoring is provided to provide a compensation indicator for a long haul industrial steam pipeline rotation compensator.
