1) quick-closure check valve
快闭止回阀
1.
The structure and theory of quick-closure check valve, pilot slow-closure butterfly valve and imperfect-closure check valve are introduced.
通过总结水锤的传统防护措施及其适用性,介绍了快闭止回阀、液控缓闭蝶阀及不完全关闭止回阀的结构和原理,并分析了后两者在高扬程泵站输水系统中的应用及效果,指出了在处理方法上的优、缺点,以及在使用时应注意的问题。
2) 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
3) rapid closing stop valve
快速截止阀;快速关闭阀
4) hydraulic control slow closing check valve
液控缓闭止回阀
1.
In pressure water supply pipeline,because of the designed hump and too rapid closing of hydraulic control slow closing check valve in the outlet,water hammer due to cavities collapsing was generated when the pump was closed.
在压力供水管路系统中,由于设计有驼峰且出水液控缓闭止回阀慢关过程过快,将导致正常关阀停泵时断流弥合水锤的产生。
5) vaporizing slow-close check valve
汽化缓闭止回阀
6) wee-resistance buffer valve
微阻缓闭止回阀
1.
For the long water supply pipeline, the prevention effect of adding hydraulic control butterfly valve at pump exit was better than that of installing wee-resistance buffer valve.
计算结果表明:正负水锤防护措施的有效结合,避免了严重的水锤压力,保证了管道运行的安全;对长供水管道,水泵出口安装液控蝶阀比微阻缓闭止回阀的水锤防护效果好。
