Definitions

  • the invention relates to a nozzle with the features specified in the preamble of claim 1.
  • the starting point of the invention are those nozzles in which a separate nozzle head is attached to a component forming a flow channel by means of fastening means. So it is e.g. customary, in each case to provide a thread on the component containing the flow channel and on the nozzle head, in order to screw the component forming the flow channel to the nozzle head. These nozzles require a relatively large production cost. In addition, especially those nozzles in which the flow channel-containing component is screwed into the nozzle head, the disadvantage that the nozzle head increases the cross-sectional dimensions of the nozzle, which can result in the nozzle under cramped installation conditions due to the cross-sectional dimensions of the nozzle head worst case not applicable at all.
  • the invention has for its object to provide a nozzle with small cross-sectional dimensions, which is easier to produce compared to the previously known nozzles. Another object of the invention is to provide a related method of manufacturing a nozzle.
  • the basic idea of the invention is, in the case of a nozzle whose flow channel opens into a nozzle head, to fasten the nozzle head on the output side of the flow channel in a material-locking manner on a component forming the flow channel. That is, the nozzle head having at least one discharge port for discharging a fluid is connected to the flow channel-containing member by means of, for example, an adhesive, soldering or welding connection. Accordingly, in the nozzle according to the invention no separate or formed on the components to be fasteners are required, which significantly reduces the cost of producing the nozzle according to the invention over that of previously known nozzles.
  • the nozzle head is attached to a surrounding the flow channel end side of the component.
  • the nozzle head rests against the component at least in an edge zone surrounding the flow channel, wherein the contact surfaces of component and nozzle head are glued, welded or soldered together.
  • the cross-sectional dimensions are only slightly larger than the inner cross-section of the flow channel, since the nozzle heads must overlap the edge of the flow channel only to a small extent. In this way, the nozzle cross section is advantageously dependent only on the cross section of the component containing the flow channel.
  • a particularly slender embodiment of the nozzle according to the invention can be achieved if, as is also advantageously provided, the flow channel is formed by a tube, at the downstream end of which the nozzle head is arranged.
  • the nozzle head can advantageously have at least two outlet channels which are angled towards one another such that the center axes of the outlet channels intersect outside the injection nozzle.
  • this embodiment of the nozzle head causes a collision of the fluid jets flowing through the outlet channels, which ultimately leads to an atomization of the fluid and thus to a broad and fine distribution of the fluid.
  • the distance of the crossing point of the center axes of the outlet channels from the nozzle is smaller than the diameter of an outlet channel. This has the consequence that the fluid jets flowing through the outlet channels partially collide already within the nozzle head, which expediently has on its outer side a trough-shaped recess in which the outlet channels open together.
  • a good flow of the outlet channels formed on the nozzle head can advantageously be achieved in that the inner cross section of the flow channel widens at its downstream end.
  • the cross section of the flow channel increases conically in an end region in the direction of the nozzle head adjoining the flow channel.
  • a chamfer is preferably formed on the inner diameter of the nozzle at the downstream end of the tube to form such a cross-sectional widening.
  • the nozzle according to the invention is then, if, according to a further advantageous embodiment, a sheet metal part forms the nozzle head.
  • a sheet metal part forms the nozzle head.
  • the use of a sheet metal part as a nozzle head is particularly useful when the nozzle head is attached to a surrounding the flow channel end face.
  • a component provided with at least one outlet opening, which forms the nozzle head is brought into abutment against an end face of a pipe and welded to the pipe through the component on the side facing away from the pipe.
  • a through-welding of the component is provided, with which the component or the nozzle head is welded to the end face of the tube.
  • the through-welding of the nozzle head is particularly simple if it is formed by a flat sheet-metal part.
  • the nozzle head is expediently welded in a circular manner to the pipe via the end face of the pipe.
  • the component forming the nozzle head is welded to the tube by means of a laser beam welding, since good deep welding with a very small beam diameter is possible with laser beam welding methods and these methods can be easily automated.
  • the heat is relatively low, so that the discharge channels can be processed before welding.
  • this is expediently chamfered at its downstream end at its inner diameter. The chamfering can be done for example by sinking or other cutting methods.
  • the component to the pipe is preferably on the Component, preferably formed by drilling, the at least one outlet opening.
  • a tube 2 forms a flow channel 4.
  • a nozzle head 6 is firmly bonded, which will be discussed further below. Since the illustrated nozzle is intended for use in a hot environment, the tube 2 is surrounded radially by a heat sink 8, with which the heat absorbed by the nozzle can be returned to the environment of the nozzle.
  • FIG. 2 In particular Fig. 2 can be seen, two outlet channels 10 and 12 are formed on the nozzle head 6, which are aligned such that a center axis B of the outlet channel 10 and a center axis C of the outlet channel 12 cross outside of the nozzle at a crossing point D.
  • both the central axis B of the outlet channel 10 and the central axis C of the outlet channel 12 is chamfered at an equal angle of approximately 30 ° to the central axis A of the tube 2.
  • the intersection point D of the center lines B and C is so on the center line A of the tube 2.
  • the intersect Outlet passages 10 and 12 extends at the downstream end of the tube 2 in the direction of the nozzle head 6 initially in a conical section 16, which merges into a cylindrical portion 18.
  • the nozzle head 6 is located on the downstream end face of the tube 2 flat and is connected there with a weld 20 through the nozzle head 6 through to the tube 2 cohesively.
  • the executed as a laser beam welding weld 20 extends in a circle over the entire end face of the tube 2, so that the nozzle head 6 is continuously connected to the tube 2 gas and liquid-tight.
