Description

Nach dem Hauptpatent wird das in gewöhnlichen Niederdruckacetylenentwicklern erzeugte Gas dadurch auf einen erhöhten, zum Betriebe von Hochdruckgasschmelzschweißbrennern geeigneten Druck gebracht, daß es mittels eines Gasstrahlgebläses verdichtet wird, als dessen Treibmittel nach dem Dis- - sousgasverfahren aufgespeichertes Acetylen von entsprechend hoher Spannung dient.
Gegenstand vorliegender Erfindung ist eine Abänderung dieses Verfahrens, welche darin besteht, daß an Stelle des aus Dissousgasflaschen entnommenen Acetylengases ein anderes brennbares Gas verwendet wird, das sich ohne Anwendung des Dissousgasverfahrens in Druckbehältern speichern läßt. Solche Gase, wie z. B. Wasserstoff, Methan, Blaugas, sind zwar für die in Betracht kommende Art der Hochdruckgasschmelzschweiao ßung dem reinen Acetylengas an sich nicht vollkommen gleichwertig, indessen kann bei dem mäßigen Verdünnungsgrade, welchen das Acetylengas durch die Verwendung solcher Gase als Treibmittel in einem zu seiner Veras dichtung dienenden Strahlgebläse aus seiner Aufmischung mit dem verdichteten Acetylengas ergibt, in unschädlichen Grenzen gehalten werden. Dies ist um so leichter möglich, als solche Treibgase mit höherem Druck als Dissousacetylengas zur Verfügung stehen und ohne Gefahr mit solchem in dem Gasstrahlgebläse mit entsprechend größerer Mengenförderleistung angewendet werden können.According to the main patent, the gas generated in ordinary low-pressure acetylene generators is brought to an increased pressure suitable for operating high-pressure gas fusion torches by compressing it by means of a gas jet blower, whose propellant is acetylene with a correspondingly high voltage, which is stored according to the dissolving gas process.
The subject of the present invention is a modification of this process, which consists in using another combustible gas instead of the acetylene gas taken from dissous gas bottles, which gas can be stored in pressure vessels without using the dissous gas process. Such gases, such as. B. hydrogen, methane, blue gas, are indeed not completely equivalent to pure acetylene gas for the type of high-pressure gas melting welding in question, however, with the moderate degree of dilution, which the acetylene gas by the use of such gases as propellants in one of its Veras The jet blower used to seal the seal results from its mixing with the compressed acetylene gas, must be kept within harmless limits. This is all the more easily possible since such propellant gases are available with a higher pressure than dissous acetylene gas and can be used without danger with such propellant gases in the gas jet blower with a correspondingly larger volume delivery rate.

Durch die Anwendung solcher brennbaren, mehr oder weniger hoch gespannten Gase ist es möglich, dem Acetylengas annähernd gleichwertige Schweißgase von einem für die Hochdruckgasschweißung geeigneten Druck mit einfachen Mitteln unter weiterer Verminderung der Explosionsgefahrquellen herzustellen. Die nach der Erfindung anzuwendenden Gase lassen sich außerdem in vielen Fällen leichter und billiger beschaffen als Dissousgas und mit einfacheren Mitteln und geringerer Gefahr auf den erforderlichen Betriebsdruck verdichten.By using such flammable, more or less highly stressed gases is it is possible to use welding gases which are approximately equivalent to acetylene gas from one for the High pressure gas welding suitable pressure with simple means with further reduction the sources of explosion hazard. To be used according to the invention In many cases, gases are also easier and cheaper to obtain than dissous gas and with simpler means and less risk of the required operating pressure condense.
