Definitions

  • the invention relates to a cutting torch with a burner head, which accommodates an exchangeable cutting nozzle, according to the preamble of claim 1.
  • a burner tip is surrounded by a sleeve. These two parts are firmly connected to each other by means of a finely threaded thread and sealed against each other ( US Pat. No. 2,897,884 ). Through a central channel in the burner tip of the cutting zone oxygen can be supplied. Fuel gas is passed through channels outwardly formed from the burner tip, which tapers conically over a portion, to an opening of the burner tip. The burner tip is connected to the burner head via metallic seals, for which purpose the burner tip is provided with cone-shaped sealing surfaces.
  • the sleeve To replace the burner tip, which is desirable because of wear or to use a differently configured burner tip or cutting nozzle, the sleeve must be unscrewed and screwed again after inserting the new burner tip close to the burner head, which should be done carefully and can be cumbersome.
  • the heating nozzle should have an outer jacket, which is provided at the upper end with a first O-ring as a sealing ring, which bears sealingly against the Schudüsenfact.
  • an outer peripheral groove for the first O-ring is provided at the upper end of the outer shell, which sealingly bears against the inner wall of an annular groove in the burner head.
  • a circumferential outer collar is provided downstream of the first O-ring, the upper side of which in the assembled cutting torch lies directly against a downwardly directed annular surface of the burner head.
  • At the bottom of the outer collar engages a fixed to the burner head coupling.
