配水器是一种设置在取水口上,当其上游水位在一定范围内变动时引取流量基本不变的取水设备。它结构简单,运行可靠,管理方便,既能量水又能配水,造价也比较低。它既可以用在自动化灌区中,也可以用在传统灌区的取水口或分水口上。在国外,配水器有很多型式和型号,而且都已在各国取得专利。近几年来,我们根据其工作原理和性能要求,作了一些试验研究,目前已研制出单扉型和双扉型二种配水器,试验证明,其性能曲线同国外同类产品基本相同。 The water distributor is a kind of water intake equipment which is set on the water inlet and takes the flow basically unchanged when the water level in the upstream is changed within a certain range. Its structure is simple, reliable operation, easy management, both water and water, the cost is relatively low. It can be used in both automated irrigation areas and water intakes or water intakes in traditional irrigation areas. There are many types and models of water dispensers in foreign countries, and all of them have been patented in various countries. In recent years, according to its working principle and performance requirements, we made some experimental studies. At present, we have developed two types of single-door and double-door two water dispensers. The test proves that their performance curves are basically the same as those of similar foreign products.
