Definitions

  • ABSTRACT [22] Filed: May 25, 1972 A spray nozzle having an internal bore for spray liquid and a transverse deflector plate disposed in the path of [211 App! 256678 the liquid jet from the nozzle.
  • the deflector plate is mounted on a rod extending axially through the bore of [52] US. Cl. 239/524 the nozzle and rigidly mounted by a spider having ra- [51] Int. Cl B05b 1/26 dial legs and a peripheral ring from which the legs ex- [58] Field of Search 239/518, 524, 521-523 tend both radially and axially.
  • a feature of the invention is the provision of means for maintaining a uniform spray pattern around the entire 360 of the spray.
  • the invention is applied to a nozzle of the type including an element having a central bore adapted to eject a jet of liquid axially and a radially curved concentric deflector plate disposed in the path of the jet for deflecting the jet into a radial spray extending around its entire periphery.
  • the deflector plate is supported on a rod extending axially through the bore of the nozzle.
  • An object of this invention is to provide novel and improved centering means for a supporting rod for the deflector plate in nozzles of the above type.
  • the rod is mounted in a spider having a set of radial legs carried by a peripheral ring.
  • the ring is adapted to be clamped against the end of the nozzle element by a coupling member.
  • the legs of the spider are of a width to extend axially beyond the ring with their outer edges machined to fit accurately in the bore of the nozzle. The legs thus serve to center the rod and deflector plate and the outer ring serves to clamp the same securely in place in centered position.
  • FIG. 1 is an axial section through a nozzle embodying the invention
  • FIG. 2 is a detail section taken on the line 2--2 of FIG. 1 showing the construction of the supporting spider
  • FIG. 3 is an axial section similar to FIG. 1 illustrating a further embodiment of the invention.
  • the device is shown as embodying a nozzle element of generally standard construction having a rim 11 at its leading end and an axial bore having a tapered wall 12 at its leading end and a cylindrical wall 13 atits trailing end from which the liquid is discharged in the form of a jet.
  • the element 10 At its base the element 10 has an externally threaded coupling portion 14 and an outer surface 15 tapering to the discharge end.
  • An axial rod extends through the bore of the element 10 and is supported by a spider having a series of radial legs 21 and an integral peripheral ring 22.
  • the ring 22 is machined to fit accurately against the rim 1] of the element 10 and is of a thickness to be clamped by a coupling member 25 between the rim 11 and the end of a supply pipe 26.
  • the pipe 26 carries a flange 27 to be engaged by the coupling member 25 which is threaded onto the threaded portion 14 of the element 10.
  • the radial legs 21 extend axially beyond the ring 22 and have outer edges 28 which are machined to fit accurately against the tapered wall 12 of the element 10 so as to center the spider and the rod 20 when inserted in the bore of the element and to be clamped rigidly in place when so centered by means of the coupling member 25.
  • the surface of the ring 22 which engages the rim ll of the nozzle element is accurately machined for holding the rod 20 and deflector disc 30 in rigid axial alignment with the nozzle element 10.
  • the rod 20 carries at its trailing end a deflector disc 30 having a symmetrically curved forward surface 31 adapted to deflect the liquid of the jet radially in all directions to form a 360 spray pattern.
  • the accurate centering of this deflector ensures a uniform spray pattern around the entire periphery of the nozzle.
  • the deflector disc 30 is shown as threaded onto the rod 20 and may be fixed in adjusted position by a set screw 33.
  • the rearward surface 34 of the deflector disc 30 is shown as convex to improve the air flow thereover if used to pass an air stream through the spray zone as in a gas washing apparatus.
  • the nozzle is, however, adapted for general use where a 360 spray pattern is required.
  • the rod 20 and the deflector plate 30 are accurately centered and positioned during assembly by the contact in surfaces of the outer portions 28 of the legs 21 and the tapered surface 12 of the bore in the element l0 and are securely and rigidly clamped by the ring 22 against the rim 11 of the nozzle element.
  • the parts may be removed and replaced in a similar manner and, when so clamped in position, the deflector disc 30 is accurately centered without further manual adjustment.
  • FIG. 3 The embodiment of FIG. 3 is similar to that above described and corresponding parts have been given the same reference numbers with the suffix a.
  • the outer edges 28a of the spider legs 21a are shown as seated against the corresponding tapered bore 12a of the nozzle element with the retaining ring 22a spaced from the end 11a of the nozzle element 10a.
  • a coupling member 40 is threaded onto the leading end of the nozzle element 10a and has an inner peripheral flange 41 which engages the retaining ring 22a and exerts pressure for seating and centering the spider in the bore 12a of the nozzle element.
  • the surface of the flange 41 which engages the ring 22a is accurately machined to hold the rod 20a and disc 30a in accurate axial alignment with the nozzle element 10a.
  • the supply pipe 26a is threaded into the coupling member 40.
  • a spray nozzle having an axial bore for ejecting a jet of liquid, a transverse'deflector plate disposed in the path of said jet and a supporting rod for said plate extending axially through said bore, a supporting spider for said rod having a set of radial legs and a peripheral ring carrying said legs, said nozzle having an end rim against which said ring is adapted to be seated and said legs having outer end portions shaped to fit accurately in said bore of said nozzle for centering the spider and rod.
  • a nozzle asset forth in claim 1 in which said bore is tapered and the outer end portions of said legs are said rim of said nozzle.
