Abstract[English] A valve device (100), comprising a valve seat (50), and a movable valve member (20) and a fixed valve member (10) which are arranged inside the valve seat, wherein the fixed valve member is provided with a fixed valve member flow channel comprising a plurality of first flow channels (11); the movable valve member is provided with a plurality of closing portions, such that inlets of the plurality of first flow channels are opened or closed simultaneously by means of the plurality of closing portions; and a fluid flowing into a fluid inlet (51) flows through the plurality of first flow channels and is converged and discharged from a first fluid outlet (52). By means of the synchronous opening or closing of the plurality of first flow channels, the valve device significantly improves the switching response speed, and reduces the stroke, such that the stress on the valve device is more uniform, thereby reducing wear and prolonging the service life of the valve device.[French] L'invention concerne un dispositif de soupape (100), comprenant un siège de soupape (50), et un élément de soupape mobile (20) et un élément de soupape fixe (10) qui sont disposés à l'intérieur du siège de soupape, l'élément de soupape fixe comportant un canal d'écoulement d'élément de soupape fixe comprenant une pluralité de premiers canaux d'écoulement (11) ; l'élément de soupape mobile comportant une pluralité de parties de fermeture, de telle sorte que des entrées de la pluralité de premiers canaux d'écoulement sont ouvertes ou fermées simultanément au moyen de la pluralité de parties de fermeture ; et un fluide s'écoulant dans une entrée de fluide (51) s'écoule à travers la pluralité de premiers canaux d'écoulement et est fait converger et évacué par une première sortie de fluide (52). Au moyen de l'ouverture ou fermeture synchrone de la pluralité de premiers canaux d'écoulement, le dispositif de soupape améliore considérablement la vitesse de réponse de commutation, et réduit la course, de telle sorte que la contrainte sur le dispositif de soupape est plus uniforme, ce qui permet de réduire une usure et de prolonger la durée de vie du dispositif de soupape.[Chinese] 一种阀装置(100)，包括阀座(50)以及设置于阀座内的动阀件(20)和定阀件(10)，定阀件设置有定阀件流道，定阀件流道包括多条第一流道(11)，动阀件设置有多个封闭部，以通过多个封闭部同时打开或同时封闭多条第一流道的入口；从流体入口(51)流入的流体流经多条第一流道在第一流体出口(52)汇流排出。该阀装置通过多个第一流道同步开闭，大幅提升了开关响应速度，降低了行程，使阀装置受力更均匀，减少了磨损并延长了阀装置的使用寿命。
