ABSTRACT:
A flow diffuser is shown for use with a flow control valve which produces laminar flow patterns in the fluid upon exiting the control valve. The flow diffuser is formed from a cylindrical body and is situated inside a flow control valve. Fluid enters the flow diffuser after passing the poppet. The inlet opening for the flow diffuser is on the axis of the body. The flow is then radially diverted through a plurality of outlet passages. The outlet passages converge to return the flow to a single stream. The walls of the outlet passage are defined by vanes within the body of the flow diffuser. Upon exiting the flow diffuser the fluid enters a transition zone until reaching the outlet port of the flow control valve. The flow diffuser eliminates turbulence, thereby reducing energy loss in the flow, wear on the valve, and noise.
