1 Inch Venturi

Meanwhile,  1-inch Venturi injector can inject liquid fertilizer and other water solvents into the pipe network of the irrigation system. So this kind of fertilizing device was widely applied in micro-irrigation, drip irrigation, and micro-spray systems.

1. Low cost, easy operation, stable fertilizer concentration, free extra power ;
2. Realize fertilizing in proportion to maintain a constant nutrient concentration;
3. Realize the integration of irrigation & fertilization and save fertilizer and manpower;
4. PP material with high resistance to chemicals used in agriculture;
5. Built-in check valve to prevent the injection liquid backflow;
6. Adaptable to all micro-irrigation, drip irrigation, and micro-spray systems;
7. Easy installation, operation, and maintenance.

Use three-way, elbow, and other parts to connect the Venturi fertilizer injector in parallel to the main valve of the main waterway.
Turn down the waterway main valve when working, it will form a differential pressure which makes the water flow through the branch
of the Venturi injector. The Venturi tube is a kind of converging passage that gradually widens (see diagram). When the water flow
Through the narrow Venturi pipe’s throat, the flow rate could increase and the pressure could decreased. When there is a smaller diameter pipe accordingly equipped in the Venturi tube’s throat, the created negative pressure would draw the liquid fertilizer into the pipe system to fertilize from the exposed fertilizer bucket. The switch valve at the entrance can adjust the
proportion of the intake of water and fertilizer.
