Title (EN) FLUID-DRIVEN VALVE
(FR) SOUPAPE ENTRAÎNÉE PAR UN FLUIDE
(JA) 流体駆動弁
Abstract:
(EN) Provided is a fluid-driven valve making it easy to continue with continuous monitoring and capable of detecting the leakage of an operating fluid from an actuator even when the actuator is being operated. Pressure sensors (21, 22) are provided on a pressure-bearing surface inside an actuator (3) on which the pressure of an operating fluid acts, and on a non-pressure-bearing surface inside the actuator (3) on which the pressure of the operating fluid does not act, respectively. A position sensor (23) for detecting the position of a valve shaft (9) is also provided.
(FR) L'invention concerne une soupape entraînée par un fluide facilitant la poursuite d'une surveillance continue et apte à détecter la fuite d'un fluide de fonctionnement à partir d'un actionneur même lorsque l'actionneur est actionné. Des capteurs de pression (21, 22) sont placés sur une surface d'appui de pression à l'intérieur d'un actionneur (3) sur lequel agit la pression d'un fluide de travail, et sur une surface qui ne supporte pas l'appui de pression à l'intérieur de l'actionneur (3) sur laquelle la pression du fluide de fonctionnement n'agit pas, respectivement. L'invention concerne également un capteur de position (23) destiné à détecter la position d'une tige de soupape (9).
(JA) 常時監視を続けることが容易で、アクチュエータからの操作流体の漏洩をアクチュエータの作動が行われている場合であっても検知することができる流体駆動弁を提供する。 操作流体の圧力が作用するアクチュエータ(3)内部の受圧面、および、前記操作流体の圧力が作用しないアクチュエータ(3)内部の非受圧面のそれぞれに圧力センサ(21)(22)が設けられている。弁棒(9)の位置を検知する位置センサ(23)が、さらに設けられている。
