Abstract：Based on theoretical deduction and experiment, this article establishes both functional and emperical formula among throat pressure, front and back pressure difference, outlet pressure and geometrical parameters of parallel connection venturi tube. What is more,through compiling the computer program, it draws the curves of hindering coefficients of front and behind inclinations of venturi tube under the conditions of different throaty diameters or different ranges of throaty pressure, and offers optimum selection parameters of front and behind inclinations of parallel connection venturi tube. This will offer important foundation of theory and practice which will help people design, study the parallel connection venturi tube and popularize its applications to sprinkler irrigation system.
