FLUID FLOW-RESISTANT DEVICE LIMITING FLOW VELOCITY

摘要

PURPOSE: A fluid flow-resistant device for restricting fluid speed is provided to prevent noise, vibration, cavitation, and erosion caused by fluid by restricting the speed of fluid passing through a fluid processing device. CONSTITUTION: A fluid flow-resistant device for restricting fluid speed is arranged in a fluid processing device. The fluid processing device comprises a body(10), a plug(30), a seat ring(40), and a cage(50). Labyrinth grooves are formed on the circumference of one among the plug, the seat ring, and the cage.
