来自热塑性管道
通常，配电网（干线、副干线和歧管）由PN 6.0和10.0 bar的热塑性管道和配件（PVC、PE、PP等）组成。然而，对于主管、支管和歧管，也可以使用其他类型的管道，例如快速连接的轻型钢管。过去，永久组装的埋地刚性PVC管用作主管，14.2第14章-滴灌加压灌溉技术图14.1-主管、歧管和滴灌支管。潜艇和消防栓在水面上的要求位置升起。最近，50–75 mm HDPE管道（PN 6.0 bar）已在小型农场的整个配电网络中使用。也可以使用直径较大的聚乙烯管，但成本比相同尺寸的刚性PVC管高。系统压力范围为2.0至3.0巴。因此，所有滴灌系统可分为低压、局部、固体永久或季节性安装系统。滴水器（滴水器）滴水器是由优质塑料制成的小型滴水器。它们安装在频繁空间的小型柔性PE管（软管）上。水在约1.0巴的压力下进入发射器，并以1.0–24升/小时的低速率在零压力下以连续液滴的形式输送。
根据耗散能量
（压力）。滴头分为两类：•孔口型，小流量面积为0.2–0.35 mm2；•长径型，流动面积相对较大，为1–4.5 mm2。这两种类型均采用不同的机构和工作原理制造，如涡流二极管、隔膜或浮板用于孔滴，迷宫式路径用于长径型。现在市场上所有的滴头都是乱流滴头。水滴的特点还在于与侧面的连接类型：在线，即借助冲头插入管壁；如果切割管道以手动或机器插入滴头。在线多出口发射器还可以提供四到六个“意大利面”管出口。供应商应规定的规格为：•在推荐的工作压力下，通常为1.0 bar，发射器排放（流速）；•发射器流量与压力变化之间的关系，以及具有不同间距和坡度的发射器管道的最佳长度；•连接类型；•过滤要求；•变异系数（cv）（发射器的制造变异性）。滴水器可以作为一个单独的项目提供，而不是内置在管道中，请参阅
From thermoplastic pipes
In general, the distribution network (trunk, sub trunk and manifold) consists of thermoplastic pipes and fittings (PVC, PE, PP, etc.), PN 6.0 and 10.0 bar. However, for main pipes, sub pipes and manifolds, other types of pipes can also be used, such as quick connect light steel pipes. In the past, permanently assembled buried rigid PVC pipes were used as main pipes, 14.2 Chapter 14 - Drip irrigation pressurized irrigation technology Figure 14.1 - Main pipes, manifolds and drip irrigation branches. Submarines and fire hydrants are raised at the required position on the water surface. Recently, 50 – 75 mm HDPE pipes, PN 6.0 bar, have been used throughout the distribution network in small farms. Polyethylene pipes with larger diameters can also be used, but at a higher cost than rigid PVC pipes of the same size. The system pressure range is 2.0 to 3.0 bar. Therefore, all drip irrigation systems can be classified as low pressure, local, solid permanent or seasonal installation systems. Drippers (Drippers) Drippers are small drippers made of high-quality plastic. They are installed on small flexible PE pipes (hoses) in frequent spaces. Water enters the emitter at a pressure of about 1.0 bar and is delivered as a continuous droplet at zero pressure at a low rate of 1.0 – 24 l/h.
According to dissipated energy
(pressure). Drippers are divided into two categories: • Orifice type, with a small flow area of 0.2 – 0.35 mm2; • Long diameter type with relatively large flow area of 1 – 4.5 mm2. Both types are manufactured using different mechanisms and operating principles, such as vortex diodes, diaphragms or floating plates for hole drops, and labyrinth paths for long diameter types. Now all drippers on the market are turbulent drippers. The characteristics of the water drip also lie in the connection type with the side: online, that is, insert the pipe wall with the help of a punch; In case the pipe is cut to insert the dripper manually or by machine. On line multi outlet emitters can also provide four to six "spaghetti" tube outlets. The specifications that the supplier shall specify are: • At the recommended operating pressure, usually 1.0 bar, the emitter discharges (flow rate); • The relationship between emitter flow and pressure change, and the optimal length of emitter pipeline with different spacing and slope; • Connection type; • Filtration requirements; • Coefficient of variation (cv) (manufacturing variability of emitters). Dripper can be provided as a separate item, not built in the pipe, refer to
