The reflector appearance is divided into two sections, and epimere is an outside diameter d
7Be slightly larger than import mouth outside diameter d
1Externally threaded cylinder arranged, hypomere is the regular hexagon cylinder; Endoporus is divided into three sections: the endoporus epimere is slightly larger than import mouth outside diameter d for its internal diameter
1Cylindrical hole, the import mouth inserts in this hole with its hypomere; The endoporus stage casing is the up big and down small turbination reflection cavity of internal diameter, and its upper-end inner diameter equals import mouth endoporus hypomere bottom diameter d
4, endoporus stage casing bottom diameter d
5Less than upper-end inner diameter d
4, the side of reflection cavity is middle reflecting surface; The endoporus hypomere is a cylindrical outlet, the outlet inner diameter d
6Greater than import mouth endoporus stage casing inner diameter d
3The outlet upper surface is higher than the bottom in reflection cavity turbination hole, form a conical reflecting surface down that external diameter is up-small and down-big between the upper end-face edge of outlet and the turbination endoporus bottom edge, the sideline of the conical cross section of following reflecting surface and the angle between the horizontal line equal the sideline of cross section of reflecting surface round taper hole and the angle α between the horizontal line, the appearance of reflector also can be divided into two sections, epimere is the cylinder that external diameter is slightly larger than import mouth external diameter, and hypomere exports the up big and down small inverted cone body of internal diameter greater than reflector less than reflector epimere external diameter lower end external diameter for the upper end external diameter.
The hypomere of import mouth inserts in the reflector endoporus epimere, is one with the adhesive bonds.Reflector is installed in the screwed hole and is located with the external screw thread of its epimere nozzle of packing into.In operation, when liquid stream was flowed through reflection cavity from the top down, part liquid was through the reflection of upper, middle and lower reflecting surface, and impingement flow makes it become liquid bullet at a high speed and flows through the liquid stream at reflection cavity middle part, is flowed out by outlet and washes away working face.
Beneficial effect: the present invention is used for drilling well, coal mining, cutting, flushing operation.Compared with the prior art, the energy loss of the import mouth guiding gutter fluid of flowing through significantly reduces, and its rate of energy loss is reduced to 2-4% by the 10-12% of prior art; The impulsive force of liquid bullet stream improves 15-20% than prior art, when other conditions are identical, has improved scouring capability, reduces operating cost, and compared with the prior art obvious improvement is arranged.
