分析了超压泄压阀水锤防护设备的特点,主要介绍了由双向调压塔创新设计后的新型箱式双向调压塔的特点,并结合一典型输水工程即长距离、高扬程、多起伏、大管径且管道首末端高、中间低的工程案例,采用特征线法,建立水锤计算模型,对分别采用超压泄压阀和箱式双向调压塔两种水锤防护方案进行了对比研究。
The characteristics of overpressure relief valve water hammer protection equipment are analyzed. The characteristics of the new box type bi-directional pressure regulating tower after the innovative design of the bidirectional pressure regulating tower are mainly introduced. Combined with a typical water delivery project that is long distance, high lift, Multi-ups and downs, large diameter and the first and the end of the pipeline high, the middle of the low case, the use of characteristic line method, the establishment of water hammer calculation model, respectively, overpressure relief valve and box type two-way pressure regulating tower water hammer protection programs Conducted a comparative study.
