Definitions

  • This invention pertains to water-jet cutting systems, and in particular, to such systems which are augmented with an abrasive slurry and, accordingly, are defined as abrasive-jet cutting systems.
  • an abrasive-jet cutting system comprising first means comprising a supply of pressured liquid; a jet-cutting nozzle; first conduit means for communicating said first means with said nozzle for conducting pressured liquid to said nozzle; second means comprising a reservoir of slurry; third means comprising a given slurry-confining and -pressurizing vessel; second conduit means for communicating said reservoir with said vessel for supplying slurry from said reservoir to said vessel for confinement therein; third conduit means for communicating said first means with said vessel for conducting pressured liquid to said vessel for pressurizing vessel-confined slurry; fourth conduit means for communicating said vessel with said nozzle for conducting pressurized slurry to said nozzle; and a given, single, valve, interpositioned between said vessel, said reservoir, and said nozzle, having means operative in a first mode (a) to effect communication between said vessel and said reservoir, and (b) to prohibit communication between said vessel and said nozzle, and having means operative in a second mode
  • an abrasive-jet cutting system comprising first means comprising a supply of pressured liquid; a jet-cutting nozzle; first conduit means for communicating said first means with said nozzle for conducting pressured liquid to said nozzle; second means comprising a reservoir of slurry; third means comprising a plurality of slurry-confining and -pressurizing vessels; second conduit means for communicating said reservoir with said vessels of said plurality thereof for supplying slurry from said reservoir to said vessels for confinement therein; third conduit means for communicating said first means with said vessels for conducting pressured liquid to said vessels for pressurizing vessels-confined slurry; fourth conduit means for communicating said vessels with said nozzle for conducting pressurized slurry to said nozzle; and a given, single valve, interpositioned between said vessels, said reservoir, and said nozzle, having means operative in a first mode (a) to effect communication between one of said vessels and said reservoir, and (b) to prohibit communication between said one vessel and said nozzle, and having means
  • the system 10 comprises a tank 12 which comprises a store of water.
  • a tank outlet line 14 supplies water to an intensifier 16 for pressurization of the water.
  • Lines 18 and 20 conduct the pressured water to an abrasive-jet nozzle 22.
  • a vessel 24 is provided for confining slurry therein, and for pressuring the confined slurry by means of a piston 26 movable therein.
  • Vessel 24 has a return line 38 for water to return to the tank, pursuant to a translation of the piston 26 in the arrowed direction (as the vessel 24 is charged with slurry).
  • a control valve 40 interpositioned therein.
  • Valve 40 is kept in its closed position when vessel 24 is being supplied with pressured water from intensifier 16, and is kept in its open position when vessel 24 is being supplied with a new charge of slurry. To insure these conditions, valve 40 is coupled to valve 32, as the dashed linkage 42 signifies, for coincident operation.
  • a line 44 communicates with line 18, via a throttle valve 46, for the purpose.
  • valves 32 and 40 When the vessel 24 is fully charged with slurry from the reservoir 28, valves 32 and 40 are operated; valve 32 is turned ninety degrees to the left (i.e., counterclockwise), to communicate line 36 with a nozzle inlet line 48, and coincidentally valve 40 is shut off. Pressured water, then, enters the vessel 24 to force the piston 26 downwardly (a) to pressurize the slurry in the vessel 24, and (b) to expel slurry therefrom, into the nozzle 22, via line 48.
  • Nozzle 22 is of the same structure as disclosed in my aforecited co-pending patent application.
  • the Figure 2 system 10a has a pair of vessels 24 and 24a which function alternatively. That is, as one of the vessels is being re-charged with slurry from the reservoir 28, the other is supplying pressured slurry to the nozzle 22.
  • valve 32a interpositioned between the reservoir 28, nozzle 22 and vessels 24 and 24a, serves a dual function. In the positioning shown, it communicates line 34 with line 36, and communicates line 36a with line 48. When turned ninety degrees (in either direction), valve 32a communicates line 34 with line 36a, and line 36 with line 48.
  • valve 40a has two operative positionings, and conducts water therethrough in both. As shown, it communicates fully through line 38, to allow vessel 24 to be re-charged with slurry, and it communicates line 38a with line 44 to expel pressured slurry from the vessel 24a. In its alternative positioning, valve 40a interrupts common flow through both legs of line 38. It connects vessel 24, through one leg of line 38, to line 44, whereby vessel 24 expels pressured slurry to the nozzle 22. Too, in the latter positioning, valve 40a communicates line 38a with the other leg of line 38 to allow vessel 24a to return water to the tank 12.
  • Valves 32a and 40a are ganged for coincident operation via the dashed linkage 42.
