DRUCKREGELVENTIL MIT MEHRFACHEM STRÖMUNGSDIFFUSOREN

摘要

A flow-through pressure regulator includes a retainer that secures a diaphragm relative to a seat, and includes an intermediate portion, an end portion and a base portion. The intermediate portion extends along a longitudinal axis and is fixed with respect to the seat. The end portion extends from the intermediate portion and includes a concave surface facing the seat. The regulator includes multiple flow diffusers such that the end portion includes at least one aperture having a flow axis that is oblique to the longitudinal axis so as to reduce noise due to fluid flow and/or the seat forms a passage having an increasing cross-sectional area from an inlet to an outlet.
