| 摘要: |
| 通过对汤峪水电站的计算分析，确定当导叶无分段关闭装置时，调压阀流量为１．７ｍ3／ｓ，行程５２ｍｍ，导叶快关闭时间１．９９ｓ，导叶慢关闭时间１７．８９ｓ；当导叶设有分段关闭装置时，调压阀流量为１．４４ｍ3／ｓ，行程４４ｍｍ，导叶第一段关闭时间１．８ｓ，导叶两段关闭总时间４．４２ｓ，即能满足要求。 |

| Abstract: |
| By means of calculation and analysis at Tangyu Water Power Station,
some regulated parameters were determined.When the guide vane was not installed with
stage-closing devices,the flow rate of pressure regulating valve was 1.7m3/s,and the
travel was 52 mm with 1.99 s for the fast closing time of the guide vane and 17.895 for
the slow closing time;when the guide vane and operated with stage-closing devices,the
flow rate of the pressure regulating valve was 1.44m3/s,and the travel was 44 mm with
1.85 and 4.425 for the total closing time of the two stages.Both ways could meet the
design requirements |
