    摘要: The invention relates to a valve (1) for regulating a fluid flow (2), in particular a fibrous material suspension flow (2.1) preferably guided in a machine (200) for producing a fibrous material web, in particular a web of paper, cardboard or packaging paper. The valve comprises a hollow body (3) having a substantially, at least in sections, rotationally symmetrical cavity (4) with a longitudinal axis (4.L). Said cavity has at least one inlet opening (5) having a longitudinal axis (5.L) and an inlet channel (5.1), a variable and substantially rotationally symmetrical passage area (6) and an outlet opening (7) with an outlet channel (7.1). The valve also comprises a valve stem (8), which is preferably rotationally symmetrical, has in particular a valve disc (9), can be coaxially displaced in the cavity (4) of the hollow body (3), preferably by means of at least one actuating means (10), and is capable of varying the passage area (6) as a consequence of a displacement (V). The valve (1) according to the invention is characterised in that the valve stem (8) is guided in the axial direction (R) by means of at least two at least radially acting bearing units (11.1, 11.2) having a degree of freedom required for the displacement (V).

    摘要: The invention relates to a valve (1) for regulating a fluid flow (2), in particular a fibrous material suspension flow (2.1) preferably guided in a machine for producing a fibrous material web, in particular a paper, cardboard or packaging paper web, said valve comprising a hollow body (3) having a cavity (4) which at least in some sections is substantially rotationally symmetrical and has a longitudinal axis (L.4). Said cavity includes at least one inlet opening (5) having a longitudinal axis (L.5), a rotationally symmetrical confuser (6) and a cylindrical or approximately cylindrical constriction (7). The valve further comprises a preferably rotationally symmetrical valve rod (8) which can be moved coaxially in the cavity (4) of the hollow body (3) preferably by means of at least one actuating means (10), can vary the open confuser surface (A.6) as a result of a displacement (V), and in particular comprises a valve disc (9) with a valve disc diameter (D.9). The valve (1) according to the invention is characterised in that the cylindrical or approximately cylindrical constriction (7) in the cavity (4) of the hollow body (3) is dimensioned such that at least in an operating position (B), preferably in a closed operating position (BG) of the valve (1), a minimum volume flow (V
    min ) can be generated between the movable valve rod (8) and the cylindrical or approximately cylindrical constriction (7) when an open minimum annular surface (A
    min ) can be generated, which has a value of ≥ 0.1%, preferably ≥ 1%, in particular ≥ 4% of the maximum volume flow (V
    max ) of the valve (1).
