detailed information

文丘里施肥器又名文丘里吸肥器。其工作原理是通过调节球阀，利用管道收缩段使管道两端形成压差，从而使化肥吸入管道系统。

Venturi fertilizer injector is also called venturi fertilizer sucker. It follows the working principle that a pressure difference at both ends of the pipe is formed by regulating the ball valve and by using the pipe shrinkage section to suck fertilizer into the pipe system.

产品型号：Φ32、Φ40、Φ50、Φ63、Φ75、Φ90。

Model: Φ32, Φ40, Φ50, Φ63, Φ75, Φ90.

产品优点：①文丘里施肥器构造简单（由塑料管件、球阀、吸肥蛇皮管组成），造价低廉，使用方便。

②主要适用于小型微灌系统（适合小面积使用）。

③不需要外加动力设备。

④较压差式施肥罐来说，它的特点是可以保持肥液浓度的稳定。

Product advantages: ① Venturi fertilizer injector is of a simple structure (composed of plastic pipe fittings, ball valve and flexible conduit) and low cost. It can be used conveniently.

② The product is mainly applicable to small micro irrigation system (small area).

③ The product does not need additional power equipment.

④ Compared with the pressure difference fertilization tank, it can keep the fertilizer concentration stable.

文丘里施肥器的安装、使用要求：

Requirements for installation and use of venturi fertilizer injector:

文丘里施肥器与过滤器配套使用；安装顺序为先施肥，后过滤。防止未完全溶解的化肥流入管道系统堵塞滴头；在施肥器与水源之间要安装逆止阀，防止农药肥液污染水源；灌溉完毕后应用清水冲洗等。

Venturi fertilizer injector is used together with filter. Fertilizer application is before filter. It can prevent fertilizer not dissolved completely flowing into the pipe, otherwise the dropper will be blocked. A cut-off valve shall be installed between the fertilizer injector and the water source, in case of water pollution caused by pesticide fertilizer solution. The product shall be flushed with clean water after irrigation.
