valve-closing time

The results indicated: Adopting the synchronous measure method of high distinguishing two-CCD for the very first time, the details of the flow field which is behind reversed tainter valve were acquired;

研究成果表明：首次采用高分辨率双CCD同步测量方法，获得了反弧门后精细的水流流场；

Equipped with flow regulator in system, electro-hydraulic proportional speed regulating valve can decrease leveling time in high speed gear, and ensure leveling accuracy in low speed gear.

系统中设有流量调节环节，电液比例调速阀在快挡可以缩短整个调平时间，在慢挡可以保证调平精度。
