Definitions

  • the invention has for its object to provide a blasting unit for sandblasting equipment that is able to withstand the aggressive flow of an air-jet mixture, in particular an air-sandblasting mixture, in a conceivably simple construction, i. that is, the jet piece should not only be long-lasting but also functionally reliable with simple and convenient operability.
  • a connection piece 9 which can be connected to a compressed air source (not shown) via a coupling indicated at 10.
  • a compressed air source not shown
  • a connection piece 9 From the connecting piece 9, the above-mentioned pressure pipe 7, which opens into the pressure chamber 2, branches off, and on the other hand, a supply pipe 13 connected via a hose 11 to a jet piece indicated at 12.
  • the blasting piece 12 arranged at the free end of the hose 11 is provided with a blasting nozzle 14.
  • the blasting material leading outlet nozzle 8 opens into the supply nozzle 13 which is pressurized with compressed air and leads to the jet piece 12.
  • the supply connection 13 is expediently passed under the container 1 in the form of a pipe bend.
  • the blasting unit 12 is provided with a shut-off device designated as a whole as 18.
  • the shut-off device 18 can be actuated by hand and has two defined switching positions in which the passage to the jet nozzle 14 should either be completely open or completely closed.
  • the shut-off device 18 is provided with a switching lever 19, the movement of which is limited by two stop surfaces 20 and 21, which are offset here by approximately 90 ° relative to one another.
  • the shut-off element 18 is separated from the jet nozzle 14 by a short piece of hose 22, so that despite the lengthening of the jet piece 12 caused by the shut-off element 18, sufficient mobility of the jet nozzle 14 is ensured.

Claims (2)

  1. Embout de projection (12) pour appareil de sablage, constituant l'élément d'extrémité d'une gaine (11) unique raccordée à l'appareil de sablage correspondant et comprenant essentiellement, dans le sens de l'écoulement, un raccord de tuyau, un organe de fermeture (18) pouvant prendre deux positions extrêmes différant de 90°, un élément de tuyau (22) et une buse de projection (14), caractérisé par la combinaison des caractéristiques suivantes:
    a) l'organe de fermeture (18) est une soupape conique;
    b) l'enveloppe (25) de la soupape conique comporte, pour le raccordement du tuyau (11) unique venant de l'appareil de sablage et pour l'élément de tuyau (22), deux tubulures (32, 33) semblables pour le raccord à la buse de projection (14);
    c) la noix (26) de la soupape conique est en alliage dur tandis que l'enveloppe (25) et ses tubulures (32,33) sont en fonte malléable;
    d) le trou de passage (27) de la noix (26) se prolonge, lorsque la soupape conique est ouverte, par des sections d'écoulement (34) de plus grand diamètre et contigües;
    e) la section d'écoulement (34) située du côté entrée a un diamètre intérieur supérieur au diamètre intérieur du tuyau (11);
    f) les tuyaux (11, 22) sont assemblés bout à bout avec les tubulures (32, 33) de l'enveloppe, des manchons (35) étant vissés sur les tubulures (32,33) et étant reliés, par des goupilles (36) aux tuyaux (11, 22) de telle manière que lors du vissage des manchons (35) les faces frontales des tuyaux s'appliquent hermétiquement contre les tubulures (32,33) de l'enveloppe.
