Description

Pierwszenstwo: Opublikowano: 8. I. 1966 50262 KI.MKP 4g, 46 F~2*-j F23J Twórca wynalazku: mgr inz. Ryszard Malentowicz Wlasciciel patentu: Zaodrzanskie Zaklady Przemyslu Metalowego im.Marcelego Nowotki, Zielona Góra (Polska) Urzadzenie do regulacji doplywu acetylenu podczas ciecia stali recznym palnikiem Przedmiotem wynalazku jest urzadzenie do regu¬ lacji doplywu acetylenu podczas ciecia stali recz¬ nym palnikiem. Proces ciecia zaczyna sie od na¬ grzewania stali do temperatury topnienia.Nagrzewanie przeprowadza sie normalnym plo¬ mieniem acetylenowotlenowym. Po nagrzaniu stali do temperatury topnienia w chwili wlaczenia strugi tlenu, zmniejsza sie zapotrzebowanie na acetylen, poniewaz znaczna czesc ciepla wytwarza sie przez utlenianie i spalanie sie stali. 10 wu tlenu, nastepuje jednoczesne zamkniecie dyszy 4, kulka 5 poprzez popychacz 3, który jest sprzezony z pokretlem 1. Wówczas acetylen dostaje sie do palnika w zmniejszonej ilosci przez dysze reduk¬ cyjna 7.Wynalazek moze byc zastosowany do kazdego palnika jako typowe wyposazenie. Oszczednosc ace¬ tylenu w wyniku zastosowania omawianego urza¬ dzenia jest dosc znaczna.W palnikach dotychczas stosowanych do ciecia stali brak jest urzadzenia do samoczynnej regulacji ilosci doplywajacego acetylenu. 1S PLPrize: Published: 8.

Ryszard Malentowicz Patent owner: Zaodrzanskie Zaklady Przemyslu Metalowego named after Marceli Nowotka, Zielona Góra (Poland) Device for The present invention relates to a device for the regulation of the acetylene supply during steel cutting with a hand torch. The cutting process begins with heating the steel to its melting point. The heating is carried out by normal oxygen-acetylene flame. When the steel is heated to the melting point when the oxygen stream is turned on, the acetylene demand is reduced as much of the heat is generated by oxidation and combustion of the steel. 10 in oxygen, the nozzle 4 is closed simultaneously, the ball 5 is closed through the pusher 3 which is coupled to the knob 1. The acetylene then enters the burner in a reduced amount through the reduction nozzles 7. The invention can be applied to each burner as a typical accessory. Acethylene savings as a result of the use of the device in question are quite significant. In the burners previously used for cutting steel, there is no device for the automatic regulation of the amount of incoming acetylene. 1S PL

Claims

1. Patent claim The device for controlling the acetylene supply according to the invention is shown by way of example in the drawing.

2. They are attached with the yoke 2 to the torch body and the acetylene feed line is connected to terminals 8 and 9.

3. After starting the cutting process, acetylene reaches the burner in two ways, through reduction nozzles 7 and nozzles

4. As soon as the melting point of steel is reached, when turned on with knob 1, a device for controlling the supply of acetylene during cutting steel with a hand torch, mounted on its body, characterized by the fact that it is provided with two nozzles (7) and (4). ) supplying acetylene to the burner, with the first nozzle (7) being the main supply of acetylene, while the second (4) operated by a knob (1), a pusher (3) and a ball (5) with a spring (6) supplying acetylene to the burner It disappears only when the demand for acetylene is increased, that is, until the steel is heated to its melting point. 5026250262 RSW "Press", Wr.
