Definitions

  • the present invention relates to a nozzle, particularly for large-diameter pipes provided with large water delivery.
  • irrigation nozzles for normal pipes having a diameter of half an inch up to a diameter equal to three quarters of an inch.
  • Such nozzles are married at one extremity with a union which is in turn connected to the pipe at the other extremity.
  • Such coupling between the nozzle and the union is generally made with a quick-action coupling of a female part, in particular the union, with a male part, the nozzle.
  • Nozzles of the known type include an inner tubular casing which can be supplied with an irrigation liquid at one extremity and provided with radial openings for the outflow of the liquid at the other extremity, an external sleeve defining with said internal casing a delivery chamber of the liquid communicating with said openings and which can be screwed on and unscrewed from the same in order to close and open in an adjustable way a central outflow passage.
  • US-A-4 785998 discloses a water spraying nozzle of the above mentioned known type, further including constantly open axial outlets in a terminal wall of the sleeve to produce a plurality of axial secondary jets at reduced pressure around the main central jet.
  • the object of the present invention is that of accomplishing an irrigation nozzle, particularly for large-diameter pipes, which also allows opening and closing of outlets for secondary jets.
  • an irrigation nozzle particularly for large-diameter pipes, comprising first means for the creation of an axial jet having variable length and conformation, said first means comprising an internal tubular casing which can be supplied with an irrigation liquid at one extremity and provided with radial openings for the outflow of the liquid at the other extremity and an external sleeve which defines with said internal casing a delivery chamber of the liquid communicating with said openings and can be screwed on and unscrewed from the same to adjustably close and open a central outflow passage, and second means for the creation of a plurality of axial secondary jets at reduced pressure round said main jet, said second means comprising a terminal wall of said sleeve provided with a plurality of circumferentially spaced axial holes, characterized in that said second means further comprise a cap rotatably superimposed over said terminal wall of the sleeve and in turn provided with a similar plurality of circumferentially spaced axial holes which can be align
  • the nozzle of the present invention thus adds to the possibility of having a long low-pressure main jet or, as an alternative, a circular high-pressure jet in the shape of a fan as for the traditional nozzles, also that of producing in combination with or as alternative to said main jet a plurality of secondary low-pressure jets which, even if the delivery is high, as in the case of large-diameter pipes, form an irrigation pattern having a comparatively limited force so as to avoid damage to plants and flowers to be irrigated. It is thus possible to irrigate at a distance while, at the same time, also watering areas which are nearer to the point of outflow of the main jet or it is possible to provide for the possibility of watering without any damage extremely near areas such as flower-beds, etc..
  • the irrigation nozzle indicated as a whole with 20 comprises an internal tubular casing 1 which can be supplied with an irrigation liquid at one extremity 2 and provided with radial openings 3 for the outflow of the liquid at the other extremity 4.
  • the nozzle 20 also comprises an external sleeve 5 which has a terminal wall 30 traversed by circumferentially spaced holes 11, an internal annular part 26 and an external lateral wall 31 which can be screwed on and unscrewed from said internal casing 1.
  • the sleeve 5 defines with said internal casing 1 a delivery chamber 6 of the liquid communicating with said radial openings 3.
  • By screwing and unscrewing the sleeve 5 closing and opening is effected of a central passage 7 for the outflow of the liquid which is defined between said internal annular wall 26 of the sleeve and a terminal appendix 27, substantially in the shape of a mushroom, of the internal casing 1.
  • the closed position is defined by the engagement of said internal annular wall 26 of the sleeve 5 with an annular gasket 35 applied to the base of the terminal appendix 27 of the internal casing 1. Between the internal casing 1 and the external lateral wall 31 of the sleeve there is accomplished a further hydraulic seal by means of an annular gasket 37.
  • a cap 10 formed by a lateral annular wall 39 rotatably coupled to the external lateral wall 31 of the sleeve 5 and a front annular wall 39 traversed by a plurality of circumferentially spaced holes 9 which can be aligned or otherwise with said holes 11 of the front annular wall 30 of the sleeve 5 for their opening or closing in relation to the angular position of the cap 10.
  • the rotation of the cap 10 is allowed between two extreme angular positions defined by the engagement of an axial protuberance 41 of the lateral wall 38 of the cap 10 with a lateral protuberance 48 of the external lateral wall 31 of the sleeve 5.
  • the holes 9 on the annular wall 39 of the cap 10 are surrounded by divergent walls 42 which define a V-shaped channel for the direction of the individual jets issuing from the holes.
  • Fig.s 2, 3, 7, 8 show the system for connecting the nozzle 20 to a quick-action union 44 for a large-diameter flexible pipe.
  • Said union 44 comprises a tubular casing 52, which can be fastened to a flexible pipe 70 by means of a ring nut 50 which is screwed onto a threaded part 53 to hold the flexible pipe, fitted over an extremity, not shown, of said tubular casing 52.
  • Said union 44 is endowed with an internal lateral wall 37 in which there is obtained a plurality of axial grooves 23, circumferentially spaced, each of which has at its side a respective seat 60 for receiving, by an axial sliding action and subsequent rotation, a rib 22 forming part of a plurality of circumferentially spaced ribs, protruding in a radial direction opposite the extremity 2 of the internal casing 1.
  • each of the ribs 22 is held inside its respective seat 60 by the engagement of one extremity 64 of the respective rib 22 against a shoulder 65 of the respective lateral wall 60.
  • the nozzle 20 is provided with a slidable tang 25 to which is attached a control cursor 24 and which can be inserted into the ribs 23 of union 44 to lock the nozzle 20 in the rotated position.
  • the secondary jets can replace the main jet by executing the closing of the central passage 7 by rotation of sleeve 5.
