摘要： PROBLEM TO BE SOLVED: To improve swirling force of water flow while suppressing clogging with foreign substances.SOLUTION: A fixed swirler 10 comprises a cylindrical tube 11 and a swirler structure 12. The swirler structure 12 is constituted of an inner cylindrical body 13, swirling flow generation vanes 14 and a turbulent flow generation stage portion 15. The turbulent flow generation stage portion 15 is caused to protrude inward in a radial direction from an inner wall surface 11A of the cylindrical tube 11 at a position in an axial direction corresponding to uppermost upstream end portions 14B of the swirling flow generation vanes 14. By such a configuration described above, since turbulent flow can be generated upstream the swirling flow generation vanes 14 by the turbulent flow generation stage portion 15, water flow passing through inter-vane flow passages 16 is reduced without forming swirling flow. Accordingly, even a small number of swirling flow generation vanes 14 can sufficiently generate the swirling flow and clogging with foreign substances can be suppressed by increasing opening areas of the inter-vane flow passages 16.

摘要： PROBLEM TO BE SOLVED: To prevent flow passages among vanes from being clogged with foreign substances without causing a disturbance of swirling flow.SOLUTION: A fixed swirler 10 comprises a cylindrical tube portion 11 and a plurality of vanes 12 that protrudes inward in a radial direction from an inner wall surface 11A of the cylindrical tube portion 11. Inter-vane flow passages 13 are provided among the plurality of vanes 12 adjacent to one another. Further, the fixed swirler 10 is configured such that each of interval dimensions among the vanes 12 adjacent to one another becomes a maximum value at each position corresponding to the inner wall surface 11A of the cylindrical tube portion 11 and becomes smaller than the maximum value at each position inwardly spaced apart from the inner wall surface 11A in the radial direction. On account of this, foreign substances can be smoothly discharged downstream from among respective vanes 12 by utilizing movement of the foreign substances reaching the vanes 12 from an upstream side to positions of the inner wall surface 11A by centrifugal force and clogging with the foreign substances can be prevented.
