Title:
TRAFFIC-VARYINGFLOW-ADAPTIVE SPRAY NOZZLE HAVING GUIDING AND SPREADING FUNCTIONSCAPABLE OF GUIDING FLOWS AND CONDUCTING SPREAD
Document Type and Number:
WIPO Patent Application WO/2017/114258
Kind Code:
A1
Abstract:
A traffic-varyingflow-adaptive spray nozzle having guiding and spreading functionscapable of guiding flows and conducting spread comprises a spray pipe (21), a fluid direction-change accelerator (11) connected to the lower part of the spray pipe (21), and a tension eliminator (12) disposed on the fluid direction-change accelerator (11). A water inlet is arranged in the upper portion of the spray pipe (21), and a water outlet is arranged in the bottom of the spray pipe (21). The center position (14) of a waterwardwater-facing surface (13) of the fluid direction-change accelerator (11) is higher than the edge portion (15), and the center position (14) of the waterwardwater-facing surface (13) transits to the edge portion (15) by means of a parabolic surface. The tension eliminator (12) protrudes from the waterwardwater-facing surface (13). A first end of the tension eliminator (12) is close to the center position (14), and a second end of the tension eliminator (12) is close to and protrudes out of the edge portion (15). The thickness of the tension eliminator (12) increases from the top to the bottom, and the thickness of the waterwardwater-facing surface (13) increases from the center position (14) to the edge portion (15). The traffic-varyingflow-adaptive spray nozzle having guiding and spreading functionscapable guiding flows and conducting spread can avoid the problem of non-uniform water spraying caused by that twisted water flows cannot in failure to overcome its water surface tension and gathers together at the water deflector due to the low water level and pressure and insufficient motion energy when a real-timethe water pressure is a non-standard water pressure.
