A gate member cooperates with the discharge orifice and is movable along the discharge orifice in order to present a closing surface to the extremity thereof, whereby the opening area of said discharge orifice can be varied for controlling the flow rate to the collecting main. The gate member is a spherical cap with a concave closing surface. The gate member is configured to pivot around a pivoting axis to expose the discharge orifice and to cover the discharge orifice, respectively.
