1) flap valve
拍门
1.
Study on Dynamic Characteristics of Flap valve and Hydraulic Buffer;
大型拍门液压缓冲装置试验研究
2.
The spherical floating flap valve develops from the ball-shell-type flap valve.
球面浮箱式拍门是在球壳形拍门基础上经改进提出的一种新型拍门,它吸收了球壳和浮箱式拍门的优点,结构轻巧、运行阻力和闭门撞击力小。
3.

结合湖北樊口泵站大型拍门模型试验 ,介绍了拍门及液压启闭系统模型相似设计方法 ;运用微机动态测试系统实测了不同装置扬程下两种不同渐变缓冲方案的拍门动态参数及启闭机油缸内压力变化过程 ,根据模型试验结果合理确定了樊口泵站拍门技术改造中截流渐变回油口槽道面积方
2) board
[英][bɔ:d] [美][bɔrd]
拍门
1.
Reduction of water column separation accompanying transient flow at two points by intercepted one-way water&board;
单向注水与拍门削减断流弥合水锤的试验研究
2.
The experiments indicate that the waterhammer due to separated cavities collapsing at two points can be reduced by intercepting air,or installing elevated-dropped board or,adopting them simultaneously,but the range of pressure reduction and eparation length is distinct.
试验表明 ,泵系统瞬变过程中在两处断流处单独注气 ,或在系统末端仅设置升降式拍门 ,或同时进行注气和拍门操作 ,都可削减两处的断流弥合升压 ,但削减压力的幅度及各处断流的长度不同 :单独采用注气措施对削减系统首端的断流弥合水锤压力最有效 (aA ≈ 0 。

怪得春光不来久，胡中风土无花柳。天翻地覆谁得知，
如今正南看北斗。姓名音信两不通，终日经年常闭口。
是非取与在指撝，言语传情不如手。
