柱塞向上运动过程中能够保持有效的密封，流线型的设计使其在大流量流体中下降过程中可以消除停机时间。
The plunger maintains efficient sealing during upward travel, and streamlined design enables falls against high flow rates to eliminate downtime during cycles.
现场，由于流量控制，UN001 航班至少要延误两小时，请把飞 机从 3 号停机位拖到 28 号。
XXX, Ramp Control, there is at least two-hour delay for UN001 due to flow control, please tow the aircraft from stand 3 to stand 28.
