A New Design of Spray Nozzle to Save Energy and Transform between Low Pressure and High Pressure Automatically

LIU Xiao-yang(College of Environmental Science and Engineering,Hohai University,Nanjing,Jiangsu 210024)  
Sprinkler technique is widely used in farmland irrigation in China.Commonly-used sprinkler such as fixed sprinkler,rotational sprinkler and multi-hole pipe sprinkler can not transform between low pressure and high pressure automatically.Consequently,they can't simultaneously meet the needs of far range and near range.Pulsed sprinkler can irrigate the cropland interruptedly and evenly,however,the price of it is so high that most farmers can't afford to buy it.From the perspective of saving energy,a new sprinkler device was designed that could transform between low pressure and high pressure automatically.Because of its low cost and flexible operation,this design would be widely used in rural areas in China.
