Air-Liquid Mixing Valve of the Sprayer Based on the Two-Phase Flow Theory

To increase the insecticide effect and to decrease the environmental pollution, the automatic control air liquid mixing valve was designed based on the two phase flow theory in fluid dynamics.The experimental result showed that this valve to make the medicine liquid nebulous can avoid the droplet leak of the sprayer in the engine idling time and the low engine speed. The tiny nebula can be easily absorbed by the leaf.
