detailed information

When drip irrigation is carried out in the shed, water outlets are generally set inside each shed. Devices such as filtration and fertilization can be connected from the water outlet. The following describes the connection of pipe fittings and equipment in detail.

According to the area of greenhouse, reasonably divide the wheel irrigation group. Select a pipe with economic and reasonable pipe diameter on the basis of meeting irrigation water demand as the main pipe.

First, install the head of the whole drip irrigation system. After the pipe (PE pipe) at one end of the water outlet, use a PE outer wire to lock and directly connect a PVC inner wire ball valve of the corresponding model. Because the PVC inner wire ball valve and Venturi fertilizer applicator are inner wire fittings, one iron pair of wires can be used to connect them. In order to ensure the tightness of the connection, an appropriate amount of raw material belt needs to be wound during the connection. The other side of the venturi fertilizer applicator is screwed and connected with the mesh filter (laminated filter) of the outer wire. Finally, the mesh (laminated) filter of the outer wire is locked and connected with the PE pipe through a PE inner wire locking straight through, and a complete set of head is installed.

After the water transmission pipeline is connected from the head, the pipeline shall be arranged according to the irrigation zoning. In the greenhouse, PE pipe (or PVC pipe) can be selected as the water transmission pipeline. Generally, there is no trenching in the shed, and the pipeline is laid on the ground. The branch pipe generally adopts PE pipe or soft belt (convenient for drilling and connecting drip irrigation belt / pipe).

The last is the installation of end emitters, commonly used as drip irrigation belt or drip irrigation pipe. For the shed with PE pipe as branch pipe and drip irrigation belt for drip irrigation, the corresponding model of punch shall be used first（ Φ 16) Punch holes in the PE pipe, then install the upper pull ring bypass or reverse bus (positive bus) bypass, and then connect the drip irrigation belt with the bypass. Pipe fittings with valves can also be used, which is more convenient to control during use. The end of the drip irrigation belt can be connected with a pull ring plug, or a section of the drip irrigation belt can be cut. The end of the drip irrigation belt can be folded several times and stuffed into the cut drip irrigation belt, which makes the connection more convenient.

在大棚内的做滴灌时，一般每个大棚内部设有出水口。过滤施肥等装置便可从出水口进行连接。下面详细介绍一下管件器材连接情况。
根据大棚面积，合理的划分轮灌组。选择一种在能满足灌溉需水量的基础上，比较经济合理的管径的管材作为主管。
首先安装整套滴灌系统的首部，从出水口一端管（PE管）后，先使用一个PE外丝锁紧直通连接一个对应型号的PVC内丝球阀，因PVC内丝球阀与文丘里施肥器均为内丝管件，故可采用一铁对丝将其进行连接。为了保证连接的密封性，连接时需要缠绕适量的生料带。文丘里施肥器另一侧与外丝的网式过滤器（叠片式过滤器）进行拧紧连接。最后将外丝的网式（叠片式）过滤器通过一个PE内丝锁紧直通与PE管锁紧连接，一套完整的首部便完成了安装。
输水管道从首部连接出后，根据灌溉分区布置管道，大棚温室内，输水管可选用PE管（或PVC管均可），一般棚内不进行挖沟，管道铺设于地面。支管一般采用PE管或软带（便于打孔连接滴灌带/管）。
最后是末端灌水器的安装，常用的为滴灌带或滴灌管。对于采用PE管为支管、采用滴灌带进行滴灌的大棚，连接时先用相应型号的打孔器（Φ16）在PE管上打孔，然后安装上拉环旁通或反母（正母）旁通，然后将滴灌带与旁通连接，也可以采用带有阀门的管件，使用时更便于控制。滴灌带末端可以用拉环堵头连接，也可以剪断一段滴灌带，将滴灌带末端折叠几次后塞入剪断的滴灌带中，连接更为便捷。
