通过平衡阀瓣及其“翼型”结构，将水头损失(或位差损失)降到最小程度。流线型阀体，不再需要凹穴来帮助流体直线流通。 - The flow regime , sediment deposition and the loss of head of two head tanks of the sewage pumping station with different dimensions are studied by using a hydraulic model test method
摘要采用水力模拟的方法对两个不同结构尺寸的污水泵站高位井的水流流态、泥沙淤积及水头损失等进行了模型试验。 - In this article , through lab and engineering site trials that the physical data of new type pipe materials is corrected , the results are as follow : ( l ) the expansion coefficient of new plastic pipe materials is more large than that of iron pipe . ( 2 ) new plastic pipe materials have different heat - resisting character and according to the water temperature to choose pipe materials ; ( 3 ) the loss of head of water for new type pipe materials is more smaller than iron pipe and also correct the loss of head of water that calculated by theory ; ( 4 ) probing into the press - resistance character of new plastic pipe materials
本文通过试验室试验及工程现场试验，对新型给排水管材的几个重要的物理性能参数进行实验测定，纠正了以往的错误认识。研究结果表明： ( 1 )新型塑料管材线胀系数远远大于钢管和铸铁管，设计和施工中要严格考虑管道的伸缩； ( 2 )新型塑料管材耐高温性能各不相同，需根据管内水温选定管材； ( 3 )新型管材水头损失远小于钢管，并对原水头损失计算公式进行了修正； ( 4 )对于塑料管材的耐压性能进行了探讨。
