双向调压塔在长距离密闭输水管线中的应用

Application of bidirectional pressure regulating tower in long distance sealed water conveyance pipeline

调压塔调控是长距离输水管道水锤防护最有效、最直接的手段。本文通过大伙房水库输水二期工程干线双向调压塔的运行实践,分析了在典型工况下调压塔超压溢流和负压补水的平压调控特性,认为双向调压塔在长距离、密闭有压输水管线系统中的应用是安全可靠的,可供类似工程参考。

Regulation and control of the pressure regulating tower are the most effective and direct means of water hammer protection in long-distance water conveyance pipelines.The regulation characteristics of the over-pressure overflow and the negative pressure water supply under typical working conditions are analyzed based on the operation practice of the bidirectional pressure regulating tower of Dahuofang Reservoir in the stage II project of the water conveyance project.It is believed that the bidirectional pressure regulating tower is safe and reliable in the application of long-distance sealed pressure conveyance pipeline system,which can be used as reference for similar projects.
