The micro irrigation spray heads is an important part of the micro irrigation system. It is closely connected with the quality of spraying and the reliability of the operation of the whole system. It adopts composite the technology of hyperboloid refraction. A series of micro sprinkler heads hanging upside down have been developed, which consist of four parts of inserted pole, joint, micro pipe and nozzle. Adopting the standard size connection, all the parts can be replaced and modified; By changing the size of the nozzle, we can give a rise to a series of products with a variety of flows and specifications; Change the passageway design of the runner. According to the existing structure form and working principle of the butterfly micro sprinkler, it can be generally divided into four types of jet, centrifugal refraction and gap.

3. The use of refraction atomized micro sprinkler head or double side wheel micro sprinkler head for irrigation boasts big spraying radius, and good atomization effect. Compared with the drip irrigation zone, drip irrigation pipe, drip arrow and drip head in the china irrigation filter system, it is less affected by terrain, and can meet the irrigation needs under different conditions.
