摘要
介绍一种喷灌的压力、流量控制设备的工作原理、组成、特点 ,以及它的设计依据 .设计的压力、流量控制装置是由表面开有曲线孔的空心阀芯与弹簧的配合实现调压 .它适用于山区喷灌 ,使喷灌有良好的均匀度 ,提高了喷灌质量 .同时对设备的实验装置也作了介绍 .
A new type of equipment for spray irrigation pressure and flow rate control is introduced, including its operational principle, components, characteristics and the design basis. The flow rate control device moderates the pressure through the cooperation of a hollow valve core with a spring. The device is suitable for spray in mountain areas, and can help improve the spray homogeneity and quality. Meanwhile experimental installation of the equipment is also described.
