Description
同軸配置された二つの管からなる管路の漏れを監視する方法は特許文献1により公知である。この方法では両方の管の間の空間、即ち制御対象空間を外部空気の吸引導入によって真空より高圧の或る圧力状態に保ちながら圧力監視を行っている。この制御対象空間で圧力低下が生じると警報信号が発生され、相応する措置が開始される。
特許文献2には漏洩検知装置が述べられており、この漏洩検知装置によって同軸配置の二つの管の間の空間、即ち制御対象空間の圧力がやはり検出される。検出圧力値が設定された圧力を下まわったり、或いは上まわったりすると漏洩検出装置が応動し、相応する措置を開始することができるようになっている。
Claims (5)
- 液体又は気体状態の極低温高圧媒体用の管路破損安全装置付き真空断熱供給管路であって、外管とその内部に同軸配置された内管との二重管構造を有し、内管の内部空間が極低温高圧媒体の送給流路を形成し、内管と外管との間の空間が供給管路の真空断熱空間を形成しているものにおいて、前記管路破損安全装置が真空断熱空間内の真空圧力自体を管路破損監視に利用するものであって、外管(1)に外向きに突設されたガイド管(5)と、このガイド管(5)内に配置されて前記真空断熱空間に連通するように尾端部で外管(1)に固定された筒状ベローズ(6)と、この筒状ベローズ(6)の先端部に固定された密閉当て板(7)と、この当て板(7)に付設されてベローズ(6)の伸縮による当て板(7)の動きを検出する検知手段とを備え、前記真空断熱空間内が真空減圧状態にある時にはベローズが収縮していて前記検知手段が監視信号を出力しており、前記真空断熱空間内の真空が崩れてベローズが弾性復帰力によって伸張状態に復帰すると前記検知手段からの監視信号が途絶されることを特徴とする真空断熱供給管路。
- 当て板(7)に付設されてベローズ(6)の伸縮による当て板(7)の動きを検出する検知手段が空気圧接触検出器(8)、電気的接触検出器、近接スイッチ又は磁気センサのいずれかを含んでいることを特徴とする請求項1に記載の真空断熱供給管路。
- ベローズ(6)が金属材料又はプラスチック材料からなることを特徴とする請求項1又は2に記載の真空断熱供給管路。
- 請求項1〜3のいずれか1項に記載の少なくとも一つの真空断熱供給管路を有することを特徴とする極低温高圧媒体供給スタンド。
- 管路破損安全装置からの監視信号が途絶えたときにそれに応動して極低温高圧媒体の供給を中断又は中止する回路装置を更に備えたことを特徴とする請求項4に記載の極低温高圧媒体供給スタンド。
