Title (EN) SENSOR-EQUIPPED JOINT AND MONITORING SYSTEM USING SAME
(FR) JOINT ÉQUIPÉ D’UN CAPTEUR ET SYSTÈME DE SURVEILLANCE UTILISANT CELUI-CI
(JA) センサ付き継手及びこれを用いた監視システム
Abstract:
(EN) Provided is a sensor-equipped joint capable of reliably detecting looseness of the joint before leakage of fluid. A seal structure is provided with: a joint member that forms a flow path; and a gasket that is opposed to the joint member and that forms a seal with the joint member therebetween. A surface of the joint member that is opposed to the gasket is formed of: a first flat surface; an annular seal projection that projects from the first flat surface; and a second flat surface that is formed at a position more distant from the gasket than the first flat surface is. At least one of the second flat surface and a section of the gasket that is opposed to the second flat surface is equipped with a sensor.
(FR) L'invention concerne un joint équipé d'un capteur capable de détecter de manière fiable le relâchement du joint avant la fuite de fluide. Une structure d'étanchéité comprend: un élément de jonction qui forme un trajet d'écoulement; et un joint qui est opposé à l'élément de jonction et qui forme un joint d'étanchéité avec l'élément de jonction entre eux. Une surface de l'élément de jonction qui est opposée au joint est formée: d'une première surface plate; d'une saillie d'étanchéité annulaire qui fait saillie à partir de la première surface plate; et d'une seconde surface plate qui est formée à une position plus éloignée du joint que la première surface plate. Au moins l'une parmi la seconde surface plate et une section du joint qui est opposée à la seconde surface plate est équipée d'un capteur.
(JA) 継手の緩みを確実に流体の漏洩前に検知できるセンサ付き継手を提供する。 流路を形成する継手部材と、前記継手部材に対向し、前記継手部材との間にシールを形成するガスケットとを備え、前記継手部材のガスケットとの対向面が、第一の平面と、前記第一の平面より突出した環状のシール突起と、前記第一の平面と比べ前記ガスケットとの距離が離れた位置に形成された第二の平面と、からなり、前記第二の平面又は前記ガスケットの第二の平面との対向部の少なくとも何れか一方にセンサが設けられているシール構造である。
