1)  close slowly
缓闭
1.
The floodgate valve installed on the pipeline may realize two stages closure while there is no operating power,floodgate valve may close to 2/3 fast while lose electrical power,the rest 1/3 of it can close slowly,which not only prevented the fluid.
中小型常用闸阀采取液控缓闭装置的设想目的,是想解决常用闸阀在开启工作后,因故电源突然中断,工作机械失去动力(如水泵),管路中的液体失去动力源将会快速倒流,安装于管路的闸阀在无操作电源时能实现两阶段关闭,即停电瞬间闸阀快速关闭2/3,余1/3缓慢关闭,既避免流体快速倒流损坏工作设备和动力设备;又避免快速关断水流发生水锤现象。
2)  slowly closing
缓慢关闭
1.
Computed results revealed that the surge shaft can prevent occurrence of negative pressure effectively provided that adopt slowly closing pattern of the valve .
计算表明,调压井可有效地防止负压产生,只要水泵出口阀采用缓慢关闭方式,管道将不会产生较大的正水锤,也不会引起水泵反转速飞逸破坏。
3)  slow-closure-type valve
缓闭阀<液>
4)  slow closing device
缓闭装置
5)  slow butterfly valve
缓闭式蝶阀
1.
Based on the method of characteristics, with the methods of numerical value simulation and according to the factual situation, the computer simulation and spot test research on eliminating the water hammer effect by slow butterfly valve in Huilong high-lift water supply proiect have got a well-fit result.
基于特征线法理论,利用数值求解方法,结合实际,进行了回龙高扬程供水工程缓闭式蝶阀消除水锤的计算机仿真和现场测试研究,取得了二者相互吻合的结果,得出了缓闭式蝶阀消除水锤效果良好,可满足该供水工程安全运行的结论,从根本上消除了水锤消除器与逆止阀联合控制水锤引起的拒动作和实际运行中带来的高能耗的影响,对高扬程及长距离供水的安全生产意义重大。
6)  slow closure back pressure valve
缓闭止回阀
1.
Research on action of slow closure back pressure valve in water delivery system with air cushion surge tank;
设置气压式调压室的输水系统中缓闭止回阀作用的研究
