Durch diesen Löschmittelbehälter wird also der elektrochemische Vorgang einer Potentialdifferenz zwischen zwei Metallen innerhalb eines Elektrolyten ausgenutzt. Die zusätzlich angeordnete Elektrode kann auswechseln bar im Inneren des Behälters angebracht sein.

In addition to pure water ko = eu, especially salt solutions, e.g. B. with Manesiumchloriä Kalziümohloid Batri'ambica. rbona salty SchsumMtellSsunges network sayings and the like * into consideration. Such fillings are aggressive and make a good one Errosionssahntz necessary for the protection of the interior of Leitongen Containers and the like Among other things, leading is used for galvanizing. a. or a laek cover. Am nooh o * carefully manufactured Above. However, g is not satisfactory in all cases. The present invention relates to a chemical container far or fire extinguishing systems with a facility tungz = corrosion protection: Lm essentially thereby it is in the solvent container in an electrically conductive connection with this an additional electrode is arranged, their building material, preferably magnesium for an extinguishing agent container made of steel, on which acts as an electrolyte fire-resistant medium is coordinated in such a way) that the metal to be protected des Extinguishing agent container on a corrosion preventing electrical potential is maintained. With this extinguishing agent container, the electrochemical process of a potential difference between two metals within an electrolyte is used. The additionally arranged electrode can be exchanged in the interior of the container.

Es hat sich gezeigt, dass auch für Feuerlosohgeräte und-anlagen sowie für deren bauteile die mit ihren Füllungen häufig über lange Zeiträume aufbewahrt bleiben, im Gefahrenfalle jedoch den hohen Anforderungen an Einsatzbereitschaft und an störungsloses Arbeiten wichtiger Teile. wie Steig- bzw. Überfüllrohre, Ventile usw. genügen müssen, Anoden aus vor allem Magnesium bzw. Magnesiumlegierungen bei den aus Kostengründen meist gebräuchlichen Behältern aus Eisen bzw. Stahl einen zuverlässigen Korrosionsschutz ergeben und die in die Lösung wandernden Zersetzungsprodukte keine Störung verursachen.It has been shown that also for Feuerlosohgeräte and systems as well for their components, which are often kept with their fillings for long periods of time remain, in case of danger, however, the high demands on operational readiness and for the trouble-free operation of important parts. such as riser or overfill pipes, valves etc. must suffice, anodes made mainly of magnesium or magnesium alloys the most common containers made of iron or steel for reasons of cost result in reliable corrosion protection and the decomposition products migrating into the solution do not cause any disturbance.

Gegenüber einer Verbleiung oder Verzinkung mit den damit verbundenen Schwierigkeiten eines einwandfreien Schutzes bietet sonach der erfindungsgemässe Schutz durch Anordnung einer leicht auswechselbaren Hilfselektrode gerade bei Feuerlöschgeräten und-anlagen aller Art, wie Handfeuerlöschern, Löschtanks, Schaummittelbehältern, Zumischbehältern, Rohrleitungen dieser Apparaturen und dergl. die Möglichkeit einer Anordnung, die in der Herstellung besonders einfach ist und störungsfrei auch bei den üblichen Anforderungen an Loschbereitschaft bei längerer Aufbewahrung genügt.Compared to lead or galvanization with the associated difficulties of perfect protection, the protection according to the invention offers by arranging an easily replaceable auxiliary electrode, especially in fire extinguishing devices and systems of all kinds, such as hand fire extinguishers, extinguishing tanks, Foam compound containers, admixing containers, pipelines for these Apparatus and the like. The possibility of an arrangement which is particularly simple to manufacture and which satisfies the usual requirements for readiness to erase in the case of longer storage without disruption.

Die Auswechselbarkeit der Elektrode, z. B. durch Einschrauben, Einklemmen eines Magnesiumstabea in einen sowieso auswechselbaren Deokelstutzen und dergl. gibt jederzeit die Möglichkeit, den sich mehr oder weniger aufzehrenden Körper der Anode auszutauschen, ohne Störungen befürchten zu müssen.The interchangeability of the electrode, e.g. B. by screwing in, clamping a Magnesiumstabea in a replaceable Deokerstutzen anyway and the like. gives the possibility at any time of the more or less consuming body of the Replace anode without worrying about malfunctions.

Selbstverständlich ist eine Übungsgemägse Überwachung erforderlich. Es finden jedoch nicht, wie bei den bisher bekannten Anordnungen für Rohrleitungen schädliche oxydische Ablagerungen, Verkrustungen und dergl. statt. Die Abbildung zeigt als Beispiel einen w ro euerldscher für eine gen trostaiöhere Füllung, z. B Magnsiumchloriilösuni. Der Behälter 1 ist aus Stahlblech, die Elektrode 3 aus Magnenixat mit 2 soll die Füllung angedeutet sein. Die Elektrode 3 ist leitend und auswechselbar mit dem metallischen behälter verbunden, das Druckrohr ist mit 4 und dem Drehgriff 5 bezeichnet.Of course, monitoring in accordance with the exercise is required. However, unlike the previously known arrangements for pipelines, harmful oxidic deposits, encrustations and the like do not take place. The illustration shows a w ro euerldscher as an example for a gen trostaiöhere filling, z. B Magnesium chloride solution. The container 1 is made of sheet steel, the electrode 3 of magnesium nixate with 2 the filling should be indicated. The electrode 3 is Conductively and interchangeably connected to the metal container, the pressure tube is denoted by 4 and the rotary handle 5.
