Plastic venturi pipe

Description

Plastic venturi pipes are used for fertilizer and chemical injection along with fertilizer tanks.

Venturi pipes are installed at the head of the irrigation system, and in front of the filter. Venturi is used for fertilizer and chemical injection through drip irrigation systems and is the most efficient and economical way to feed liquid nutrients to the roots of the plants through drip irrigation systems. Fertigation is being done simultaneously along with irrigation. Plants absorb fertilizer more efficiently when it is in liquid form. It’s easy to install and ensures a regulated fertilizer injection.

Working principle

When the water (without fertilizer) enters from the 1st part and reaches the 3rd part, it accelerates with the narrowing of the section. The pressure of the accelerating fluid decreases. Since the pressure is high in the 5th section and low in the 3rd section, fertilizer absorption takes place from the high pressure region to the low pressure region. The amount of fertilization can be adjusted in section 4. When the section on the venturi widens again, the pressure reaches the same value again. Fertilized water is sent to the system from the 2nd part.
