斜接半园孔管式量水计是苏联乌克兰水利科学研究所研制的一种测量流量的量水装置。它的突出特点是:水头损失小,不被泥沙淤积和污物堵塞;结构简单,造价低廉,制造、安装、管理和使用简易;测算方便;在一定的测流范围内,量水性能稳定,有足够的量测精度。因此,它更适宜在水头宝贵、含沙量较大的低压管灌系统上应用。 为深入了解该量水计的量水特性我们进行了试验研究,现就其构造和试验成果介绍如下:
Miter semi-circular hole pipe water meter is the Soviet Union, Ukraine Institute of Hydraulic Science developed a measure of the amount of water flow device. Its prominent features are: the head loss is small, not silt and dirt clogging; simple structure, low cost, manufacture, installation, management and easy to use; easy calculation; within a certain range of measured flow, water and stable performance , There is sufficient measurement accuracy. Therefore, it is more suitable in the head of valuable, large volume of low pressure pipe irrigation system. In order to know more about the quantity and water characteristics of the water meter, we conducted a pilot study on the structure and test results of the water meter.
