METHOD AND DEVICE FOR WORK INSIDE PIPES

PROCÉDÉ ET DISPOSITIF PERMETTANT DE RÉALISER DES OPÉRATIONS À L'INTÉRIEUR DE TUYAUX
(JA)
配管内作業装置および方法
Abstract:
(EN)
Disclosed are a "method and device for work inside pipes" for very-high-powered travel inside pipes. The disclosed device is provided with an ring-shaped pressure-boundary seal, the free edges of which contact the inside walls of a pipe. The pressure-boundary seal divides the space inside the pipe into two spaces, space A and space B. The end of space A near the pressure-boundary seal is connected to a suction pump via a hose. The end of space A near the pressure-boundary seal is also connected to space B via a vacuum-breaking valve mechanism that adjusts the negative pressure inside space A. The other end of space A, away from the pressure-boundary seal, is closed. The hose is disposed inside space B.
(FR)
La présente invention concerne un procédé et un dispositif permettant de réaliser des opérations à l'intérieur de tuyaux, adaptés à des déplacements à très haute énergie à l'intérieur de tuyaux. Le dispositif de l'invention est doté d'un joint annulaire d'arrêt de pression dont les bords libres viennent en contact avec les parois intérieures d'un tuyau. Le joint d'arrêt de pression divise l'espace compris à l'intérieur du tuyau en deux espaces, l'espace A et l'espace B. L'extrémité de l'espace A proche du joint d'arrêt de pression est reliée à une pompe d'aspiration via un tuyau souple. L'extrémité de l'espace A proche du joint d'arrêt de pression est également reliée à l'espace B via un mécanisme de clapet de cassage du vide qui régule la pression négative dans l'espace A. L'autre extrémité de l'espace A, opposée au joint d'arrêt de pression, est fermée. Le tuyau souple est disposé à l'intérieur de l'espace B.

【課題】配管内における走行駆動力が非常に大きい「配管内作業装置および方法」を提供する。 【解決手段】配管の内壁にその自由端部分が接触する環状の圧力境界シールを備え;圧力境界シールは、配管の内部の空間を、圧力境界シールを境界として、空間Aと空間Bの二つの空間に分割しており;空間Aの圧力境界シールに近接した一方の端部は、ホースを介して吸引ポンプに連通されており;且つ、空間Aの圧力境界シールに近接した一方の端部は、空間Aの内部の負の圧力を調整する真空破壊弁機構を介しても空間Bに連通されており;空間Aの圧力境界シールから離れた他方の端部は閉止されており;空間Bには、ホースが配置されている。
