CONE TYPE MULTI-PERFORATED LAMINATE ORIFICE

摘要

The present invention relates to a cone type multi-perforated laminate orifice. The cone type multi-perforated laminate orifice comprises: a first orifice that is formed in a funnel shape and has a first inflow surface part with a gradually increasing diameter toward a downstream side in a flow direction of fluid and first inflow holes formed along the peripheral direction of the first inflow surface part; a second orifice that is formed in a funnel shape and has a second inflow surface part with a gradually increasing diameter toward the downstream side in the flow direction of the fluid and second inflow holes formed along the peripheral direction of the second inflow surface part; and a gasket disposed between the first and second orifices, wherein a virtual line extending in the direction of fluid vertically passing through the first and second inflow holes meets the inner circumferential surfaces of the first and second inflow surface parts.
