| 滴灌系统的输配水管道一般有干管、支管、毛管组成，其作用是为各级管道输送所需流量。 The drip irrigation system generally consists of trunk pipe, branch pipe and capillary pipe. Its function is to transport the required flow for pipelines at all levels. 目前滴灌所用管道大都为能承受一定的水压力、抗老化性能强的塑料管，干管一般采用农用UPVC管，管长一般为6米或12米，一端扩口，两管采用承插方式连接，胶圈止水。 At present, most of the drip irrigation pipes are plastic pipes which can withstand certain water pressure and have strong anti-aging performance. The main pipes are generally agricultural UPVC pipes, the length of which is generally 6 meters or 12 meters, one end of which is enlarged, the two pipes are connected by socket, and the apron is used to stop water. 支管和辅管在滴灌系统中起控制滴灌带适宜长度、划分轮灌区的作用。滴灌系统中的支管和辅管一般采用PE管材。 Branches and auxiliary pipes play an important role in controlling the suitable length of drip irrigation belt and dividing the rotation irrigation area in drip irrigation system. PE pipes are commonly used in branch and auxiliary pipes of drip irrigation system. |
