Definitions

  • a device of this type is known from DE-A-195 01 739. It has the advantage that without disassembling the lower part from the upper part of the nozzle plate in the lower part sealing O-ring is easily replaceable. When using the nozzle bar, like when rinsing or when replacing the nozzle plate, there is a risk, however, that the O-ring slips out of its bearing groove. This applies in particular if the Nozzle bar for reasons of expediency in the overall concept of the device must be installed overhead or at an angle in the needling device.
  • the invention has for its object the device according to the genus further develop that the O-ring in any position or with every use of the nozzle bar no matter whether in the intended use or when rinsing or. Like. Held in its bearing groove but still z. B. easily after damage is interchangeable.
  • a positioning strip can be inserted into the repair groove. So it becomes when assembling an O-ring First the longitudinal plate with the tensioned O-ring in the only insert the nozzle bar open lengthways and then the positioning strip along the back of the longitudinal strip into the repair groove as well inserted. The O-ring moves with the longitudinal plate in the plane of the Bearing groove, evenly over the entire length of the nozzle bar. Is the positioning strip only the O-ring from the spacers is inserted push down, with which it is inserted into the bearing groove.
  • the U-shaped bearing groove should be conical towards the outside, towards the opening, so it narrows be dovetail-shaped. It is particularly advantageous if the open side of the bearing groove seen in cross section in its clear opening larger than the O-ring, which is held tight on the longitudinal plate, but smaller than that The diameter of the relaxed O-ring is dimensioned. In this case, the O-ring no longer slip out of the bearing groove, even in the most unfavorable position nevertheless easily replaceable without dismantling the nozzle bar.
  • the housing of the nozzle bar consists of an upper part 1, which is connected to the lower part 2 is often screwed over the length by screws, not shown, from below.
  • the upper part 1 has two bores 4 and 5, of which the upper one Pressure chamber 4 and the lower one is a pressure distribution chamber 5, which is another Construction can also be omitted. Both chambers are here on one end open and screwed tight again through the covers 6 and 7. At the other end, the pressure chamber 4 has an opening 4 'through which the under Pressurized fluid is introduced.
  • the pressure distribution chamber 5 is on this End face also screwed liquid-tight by a cover 5 '.
  • the two Chambers 4 and 5 are separated from one another by an intermediate wall 8.
  • the length of the nozzle bar connects a large number of those shown in FIG Flow bores 9 in the intermediate wall 8, the two chambers, so that the in the pressure chamber 4 flowing liquid evenly distributed over the length in the Pressure distribution chamber 5 flows out.
  • the pressure distribution chamber is open at the bottom, and by the pressure distribution chamber 5 compared to the diameter of the bore narrow slot 10, which also extends over the length of the beam.
  • the upper part 1 is screwed to the lower part 2 firmly and in a liquid-tight manner.
  • the tightness is brought about by the O-ring 11.
  • a spring projection 23 which in a corresponding Groove 24 of the lower part 2 is fitted.
  • a bearing groove 12 ′′ is again introduced, in which the O-ring 12 for sealing of the nozzle plate 14 shown in FIG. 10.
  • Slot 13 introduced, which is only very narrow in its upper region and only little more than the width of the effective nozzle openings of the nozzle plate 14 open leaves.
  • the upper part 1 has the spring projection 23 at its lower end. This leaves with its outer edges 25 space for the nozzle plate 14. When pressurized with liquid it is pressed against the O-ring 12 by the liquid pressure and sealed to the slot 13. It may now be necessary for this O-ring 12 must be replaced. To dismantle the lower part 2 from the upper part 1 and thus To avoid loosening the many screws necessary over the length of the nozzle bar, is in the spring projection 23 on the bearing groove 12 '' for the O-ring 12 opposite surface milled a repair groove 26, which then through the edges 25 is limited.
  • the repair groove 26 extends in the amount of the entire length and Width extension of the bearing groove 12 '' for the O-ring 12 of the lower part 2 and corresponds in height slightly more than the thickness of the O-ring 12.
  • a dimensionally appropriate longitudinal plate 27 can be inserted, which on the Bearing groove 12 '' of the lower part 28 associated with the lower part 28 is an O-ring clamping device having.
  • the O-ring clamping device consists of two spacers 29 and 30, which are attached to the underside of the longitudinal plate 27 and one shown in FIG. 9 Diameter corresponding to the distance between the two bearing grooves 12 '' exhibit.
  • the outer contours are Spacers 29, 30 are provided with an annular groove 33, which is the diameter of the clamped held O-rings 12 is adapted.
  • a spacer can also be cylindrical be formed to lighten the O-ring 12 from the spacers 29, 30 deport.
  • the longitudinal plate 27 has a width that is apparent from FIG. 7 Worked larger, so that the tensioned O-ring 12 after covered at the top and thus also held firmly on the longitudinal plate 27.
  • a hand-insertable insertion end 31 provided at the ends of the longitudinal plate 27.
  • the bearing groove 12 ′′ is for the O-ring 12 formed at the end faces of the nozzle bar open overall, that is, at the end faces is no external limitation for the bearing groove also present there with the inner contact surface for the O-ring 12.
  • FIGS. 1-4 are the spacers 29, 30 for the O-ring much further apart on the longitudinal plate 27 attached when the z. B. from Fig. 4 resulting end position of the O-ring 12 in the bearing groove corresponds to 12 ''. In this way, the O-ring 12 is held strongly stretched on the longitudinal plate 27. This causes the diameter of the O-ring to be reduced.
  • the longitudinal plate together with the O-ring 12 in the repair groove 26 moved in the direction of the bearing groove 12 '' and thus the elongated O-ring 12 in the two bearing grooves 12 '' are introduced.
  • This movement of the longitudinal plate 27 is - evenly distributed over the length of the nozzle bar - facilitated by a positioning strip 32, which is longer than the longitudinal plate 27 according to FIG. 1 and 1, 3 and 6, 8 inserted above the longitudinal plate 27 in the repair groove 26 becomes. 1, 3, the O-ring 12 to roll down from the spacers 29, 30, thereby forcibly according to Fig. 3 must jump into the bearing groove 12 ''. Then the positioning strip 32 4 to remove, the longitudinal plate 27 to lift and then this out pull out the repair groove 26.
  • FIGS. 7-10 An essential feature of the device shown is shown in FIGS. 7-10.
  • the bearing groove 12 '' for the O-ring 12 is not rectangular in the base of the groove, but rather dovetail-shaped. It is essential that the outside of the bearing groove is open 12 '' as shown here in cross section larger in its clear opening than the O-ring (FIGS. 7 and 8) held taut on the longitudinal plate 27, but smaller than the diameter of the relaxed O-ring 12 (Fig. 9 and 10) is dimensioned. If that is, the O-ring that is reduced in cross-section by stretching through the clear opening is moved and then expands again after being freed from the spacers 29, 30, 9, 10 the O-ring is then held firmly in the bearing groove 12 ′′ and can no longer remove itself from it.
