摘要
介绍了新型双壁滴灌带的工作原理与结构 ,研究了双壁滴灌带的水力性能、设计特征以及田间应用设计 ,并对其田间应用情况及效益进行了分析。结论认为 :该产品的壁厚 0 .15～ 0 .2 5mm ,爆破压力 45 0kPa、出水均匀度在 90 %以上 ,流态指数 0 .77,具有较好的抗堵塞性能和降低工程投资。
The principle and structure of a new type of double_wall drip tape are introduced. The hydraulic properties, design characteristics and field application design are researched, and the situation of field application and its benefit are also analyzed. It is concluded that the thickness of this product is 0.15～0.25 mm, the explosion pressure is 450 kPa, the uniformity of water application is above 90 %, and the fluid state index is 0.77. So it has good properties of anti_block, decrease cost of project and high uniformity of water application.
