- the spray holes propose a spray nozzle, characterized in that having a partial overlap region.
- the injection holes are characterized in that the injection nozzle having an arc-shaped cross section.
- the spray nozzle according to the present invention has the effect that efficient cleaning and deburring work can be performed for inaccessible places such as a deep hole or a closed hole at one end, and the cleaning or deburring work for parts having a large surface area is also quick. Yet, it is possible to process efficiently, and it is also possible to simplify the various auxiliary devices for forming the injection nozzle by washing the entire hole inner diameter only by linear movement.
- the injection nozzle of the present invention has the advantage that it is discharged while forming a strong vortex during the spraying is very suitable for high pressure injection due to its structural characteristics.
- FIG. 1 is a schematic cross-sectional view of a jet nozzle according to the prior art 1;
- Figure 2 is a perspective view showing one embodiment of a spray nozzle according to the prior art 2.
- Figure 3 is an exploded perspective view of the prior art 3.
- Figure 4 is a cross-sectional view showing a nozzle assembly according to the prior art 4.
- FIG. 5 is a schematic configuration diagram of a spray nozzle according to a first embodiment of the present invention.
- Figure 6 is a front view showing the shape of the injection hole formed toward the tip of the injection nozzle as the injection nozzle according to the first embodiment of the present invention.
- FIG. 7 is a front view showing the starting point and the final discharge point of the injection hole together.
- 9 is an exemplary view showing a three-dimensional shape of the injection hole.
- FIG. 10 is a schematic perspective view showing a second embodiment
- injection hole 10a starting point
- the spray nozzle according to the present invention can be used to spray various liquids or gases at high pressure for cleaning or deburring purposes, and is connected to a pipe to which a cleaning liquid is supplied, while processing a hole inner diameter surface of the washing object or processing an object.
- the cleaning work is performed on the outer surface. That is, the injection nozzle can be coupled to the end of the pipe by welding or screw method, the pipe is preferably used to be connected to the drive means is linear movement. Means for linearly moving the pipe and the spray nozzle are optional among various known techniques, and thus description thereof will be omitted.
- the liquid or gas to be injected at high pressure may be any liquid or gaseous phase containing a special component from water.
- the coating liquid may be sprayed onto the inner diameter surface of the deep hole or the one end of the closed hole to be used for surface coating, and the size of the spray nozzle may be increased so that only the liquid or gaseous phase is used.
- it can be used for supplying or discharging a mixture containing a sol substance or particle component.
- Figure 5 shows a schematic configuration of the injection nozzle according to the first embodiment of the present invention, the injection nozzle of the present invention at the end of the pipe (p) to which the material supplied for the purpose of cleaning or deburring, as shown (n) is combined.
- the liquid or gas introduced through the pipe p is moved to the injection nozzle n, and the injection nozzle is provided with a cavity h forming an empty space.
