雾笛
[水运] foghorn
- 雾笛阀门。
Whistle Valve. - 雾笛阀门由铜硅合金制成。
Whistle valves are made of a copper-silicon alloy. - 空气在向下运动过程中受到浮标向上的推力，使阀球将阀门里的气舱密封住，这样迫使气流进入雾笛。
Air is forced up from the buoy counterweight tube during downward motion causing the balls to seal the air ports in the valve, thus forcing the air to flow into the whistle.
