VANNE, ENSEMBLE VANNE ET PROCÉDÉ POUR MODIFIER UNE VANNE

摘要

The invention relates to a valve for liquid with a valve housing (1) defining a valve chamber (2) connecting an inlet (10) to an outlet (11). A valve obturator (3) is movably located in the valve chamber (2). The valve includes a valve seat (5) cooperating with the valve obturator (3). The valve further includes a first throttling plate (6), which throttling plate (6) has an opening (9) there through. The opening (9) determines the flow capacity and the flow characteristic of the valve. According to the invention, the throttling plate (6) is a component that retains the valve seat (5) in position in the valve and is located at a distance (d) from the valve obturator (3). The invention also relates to a valve set including the invented valve and at least one further throttle plate. The invention also relates to a method for modifying the capacity and/or characteristic of the valve.
