TWO-PHASE FLAT STREAM NOZZLE FOR SPRAIED LIQUID

摘要

PURPOSE: To enable a uniform liquid distribution and fine liquid drop distribution by providing a connector for liquid supply with a cylindrical metering inset which has a side hole and infiltrates into a mixing chamber and providing a mouth member with a throttle in a cylindrical hole having a curved bottom. CONSTITUTION: This nozzle is provided with a mixing head 10 having a first connector 13 for a gaseous medium and a second connector 17 for.atomized liquid, a tubular coupling member 20 and the mouth member 22 having a nozzle outlet 28. The end 36 of the mouth member 22 is made circular and is provided with a variable width slit 28 as the nozzle outlet 28. The second connector 17 is provided with the cylindrical blind hole 30 communicating on both sides with respectively one side holes 31 and 32 having a certain angleαwith an abscissa line 33 at the approximate center of the mixing chamber 11. The metering inset 29 of a cylindrical shape infiltrating to the mixing chamber 11 is disposed therein. Further, the mouth member 22 is provided with a stepped cylindrical 38 having the curved bottom 39. The hole step part 37 is provided thereon with the throttle 40 having a centering through-opening 42 of a sharp edge having the diameter smaller than the diameter of the hole 38.
