FLUID CONTROL VALVE

A valve (10) for controlling a flow of a fluid between a first environment (E1) to a second environment (E2) is provided. The valve (10) includes a frame (14) that fits within an aperture (18) in a divider (22) separating the first environment from the second environment. Additionally, the valve inc...

Zusammenfassung:	A valve (10) for controlling a flow of a fluid between a first environment (E1) to a second environment (E2) is provided. The valve (10) includes a frame (14) that fits within an aperture (18) in a divider (22) separating the first environment from the second environment. Additionally, the valve includes at least one gate (30) mounted and movable within the frame (14) to control a flow of the fluid between the first environment and the second environment through the aperture (18). The gate (30) includes a surface (5), wherein at least one portion of the surface includes a rough texture (70). The rough texture (70) reduces coherent vortex shedding of the fluid as the fluid passes over the gate surface (5). L'invention concerne une soupape (10) destinée à commander l'écoulement d'un fluide entre un premier environnement (E1) et un second environnement (E2). La soupape (10) comprend un cadre (14) pouvant être logé dans une ouverture (18) à l'intérieur d'un diviseur (22) séparant le premier environnement du second. En outre, la soupape comprend au moins une grille (30) montée mobile dans un cadre (14) afin de commander un écoulement de fluide entre le premier environnement et le second à travers l'ouverture (18). La grille (30) comprend une surface (5) dont au moins une partie comprend une texture rugueuse (70). Cette texture rugueuse (70) réduit le décollement des tourbillons cohérents du fluide à mesure que le fluide passe sur la surface de la grille (5).
