Lots of side tubes are radially installed in spherical water distribution house, and the external end of each side tube is equipped with a nozzle which refract the water flow around, the result of which a big sphere come into being. In the time of spraying, the water outlook is like the ball-flower of dandelion, which is quite splendid and spectacular. Owing to the fairly fine nozzle orifice diameter, the requirement on the water quality is relatively demanding. The water should be filtered, otherwise the nozzle is subject to blockage easily, which affects the spraying effects. This kind of nozzle can be applied to various kinds of fountains...This kind of nozzle is widely used in the spray ponds both indoors and outdoors.
