全射流喷头产业化开发中的问题及其改进

全射流喷头属于中国独创，在隙控式射流元件结构方面达到国际领先水平，江苏大学与企业合作，已产业化生产出IOPXH型塑料全射流喷头，但它还存在着一些问题．通过试验提出了8个需要改进的方面，最主要要解决的3个方面是：修改空心轴与连接套配合的尺寸；两片四氟圈相互之间的配合，上片与连接套静配合，与空心轴动配合，下片与空心轴静配合；信号水取水孔、信号水流入孔和反向接嘴补气孔要适当小，起到节流与节气的作用，增大驱动力矩．改进后可望能将科研知识转化成产业化产品．

Problems and improvements in batching process of complete fluidic sprinkler

Complete fluidic sprinkler is a new type sprinkler which was originated in China. The production achieves international lead in crack controlled and jet-flow element construction. Cooperated with enterprise, Jiangsu University has manufactured IOPXH plastic sprinklers, but there are still some problems. After experiment, eight respects were put forward to improve the working condition. There are three respects that are most important. Firstly, hollow shaft and connected case must be matched. Secondly, the two fluorine circle should be movable fitted, and motionless fit for upper fluorine circle and matching size, and for down fluorine circle and hollow shaft, Third, outflow and inflow holes of signal water and nourish hole should be small enough to reduce flow and gap, and heighten driving resultant moment.
