When an assembly oil pipeline is interconnected with a product oil pipelines,pressure regulating valve should be used to protect assembly pipelines by throttling and reducing pressure. In order to determine the security and reliability of a new type pressure regulating valve,numerical simulation was conducted to study the interior flow field in the pressure regulating valve. Based on computational fluid dynamics,visualization of the velocity and pressure distributions was obtained by simulating inner flow field under different openings,and the theoretical flow characteristic curve was determined. The valve was tested in the laboratory bench. The error between experimental result and simulation result was 11.5%,proving the rationality of the simulation results. The velocity and pressure contoursand the quick-opening type flow characteristic curve of the valve were presented. The new type pressure regulating valve had good abilities of throttling and reducing pressure,and could be safely and reliably used in pipelines docking.
