摘要:
The invention concerns an oxyacetylene cutting apparatus comprising a support element (10) produced from a stainless steel block which cannot be deformed, a heating element (20) permanently fixed against a bottom surface (19) of the support element (10), which heating element is produced from a massive copper block wherein are provided passages for gas fluids and the cooling fluid which communicate directly with the support element (10) corresponding conduits. At least one nozzle (30) is precisely positioned in two coaxial bores (31, 32) provided in the support element (10) and the heating element (20) respectively, the nozzle being connected to a conduit (14.6) supplying oxygen for cutting. A retaining element (40) is preferably used to enhance the precise positioning of the nozzle (30).

摘要:
L'invention concerne un dispositif de réglage pour un chalumeau à gaz alimenté en fluide gazeux par des circuits d'alimentation associés. Conformément à l'invention, le dispositif de réglage (100) comporte, pour chaque circuit d'alimentation, une boucle de régulation (110; 120; 130) permettant une régulation individuelle du fluide gazeux associé lors du fonctionnement du chalumeau à gaz (C); chaque boucle de régulation comprend un capteur de débit et/ou de pression (111; 121; 131) intégré au chalumeau et un ensemble de régulation (112; 122; 132) intercalé sur le circuit d'alimentation associé, ledit ensemble de régulation étant commandé, de préférence par un automate (140) dès qu'un écart par rapport à une valeur de consigne est signalé par un capteur. Application notamment aux techniques de décriquage, de sondage, d'oxycoupage, ou de traitements de surface.
