HIGH DRAIN PRESSURE RELEASE DAMPER FOR SHIP

摘要

The present invention relates to a pressure reduction device for a high-pressure drain line of a ship capable of reducing the pressure more while maintaining the basic shape and size of a damper pipe, reducing vibration because of the reduced pressure, increasing pressure reduction efficiency, and reducing spatial constraints. The present invention comprises: the damper pipe (10) for reducing the pressure of fluid drained at high pressure; an intake part (20) installed in one side of the damper pipe (10) to introduce the high-pressure fluid into the damper pipe (10); a drain part (30) installed under the damper pipe (10) to drain the fluid having the reduced pressure; and damper plates (40); arranged inside the damper pipe (10) and having multiple holes (41) for guiding the pressure loss of the fluid.
