Description
Patentiert im DeutschenPatented in German
Bei Kraftfahrzeugen, die mit in flüssigem oder gasförmigem Zustand verdichteten Treibgasen, wie Ruhrgasol, Butan, Propan, Methan, betrieben werden, bilden die auf dem Fahrzeug mitgeführten Druckflaschen dann eine Gefahr, wenn bei Bränden die Flaschen übermäßig erhitzt werden, so daß der Flascheninhalt sich stark ausdehnt und infolge Absperrung oder starker Drosselung der Zuleitungen zum Motor nicht oder nur ungenügend rasch entweichen kann und dadurch die Flaschen zur Explosion bringt.In the case of motor vehicles that use propellant gases compressed in a liquid or gaseous state, such as Ruhrgasol, butane, propane, methane, are operated, form the on the vehicle Pressure cylinders carried along are a danger if the cylinders are used excessively in the event of a fire be heated so that the contents of the bottle expands and as a result of blocking or strong throttling of the supply lines to the motor can not or only insufficiently quickly escape and thereby makes the bottles explode.
Es sind daher Sicherheitsventile entwickelt worden, welche sich bei Überschreiten eines bestimmten Überdruckes selbsttätig öffnen und den Flascheninhalt ins Freie entweichen lassen. Hierbei hat sich die neue große Gefahr ergeben, daß sich die ausströmenden Gase entzünden und durch die entstehenden sehr hohen Temperaturen die Druckflaschen trotz der geschaffenen Öffnung zur Explosion gebracht werden.There are therefore safety valves have been developed, which are exceeded when a open automatically at a certain overpressure and the contents of the bottle escape into the open permit. Here the new great danger has arisen that the outflowing Gases ignite and, due to the resulting very high temperatures, the pressure bottles be made to explode despite the opening created.
Es muß daher für die Fortführung der austretenden Gase aus dem Bereich der Fla· sehen durch eine besondere Ableitung gesorgt werden. Die bisher bekannten Ventile sind nun entweder so entwickelt worden, daß das von Hand betätigte Absperrventil und das Sicherheitsorgan zur Abführung der ausströmenden Gase getrennte Leitungsanschlüsse besitzen. Hierdurch werden die Kosten der Anlage größer, und es ist wahrscheinlich, daß sich der Zeitaufwand für den Flaschenwechsel zwecks Ergänzung des Gas Vorrates so erhöht, daß der Betrieb unwirtschaftlich wird; auch entsteht vor allem die Gefahr, daß die Sicherheitsventile vom Bedienungspersonal aus Bequemlichkeit nicht an die Ableitung angeschlossen werden, so daß die bei Bränden auftretende Gefahr sich vergrößert. It must therefore be used for the continuation of the gases escaping from the area of the fla see to be taken care of by a special derivative. The valves known so far are has now either been developed in such a way that the manually operated shut-off valve and the Safety device for discharging the escaping gases, separate line connections own. This increases the cost of the installation and is likely to that the time required to change the cylinder to supplement the gas supply so increased that the operation becomes uneconomical; there is also above all the danger that the safety valves are not connected to the discharge by the operating personnel for the sake of convenience connected, so that the risk of fire increases.
Es sind auch Ventilausführungen bekanntgeworden, bei denen das Absperrventil durch eine auf bestimmten Höchstdruck einstellbare Feder geschlossen wird und so gleichzeitig als Sicherheitsventil wirkt. Derart federbelastete Überdruckventile neigen im Treibgasbctrieb erfahrungsgemäß zu Undichtigkeiten durch Korrosion der Dichtungsflächen oder vom 30. Oktober 1935 abThere are also valve designs are known in which the shut-off valve by a spring adjustable to a certain maximum pressure is closed and so at the same time acts as a safety valve. Such spring-loaded pressure relief valves tend to operate in the propellant gas experience has shown that there are leaks due to corrosion of the sealing surfaces or from October 30, 1935

Gegenstand der vorliegenden Erfindung ist nun ein Ventilkörper, der Sicherheks- 5* und Absperrventil in eine öffnung münden läßt, in dem aber beide Ventile getrennt voneinander in üblicher Weise ausgebildet sind ; und parallel geschaltet werden. Wenn das .; Sicherheitsventil in Tätigkeit tritt, strömen die Gase in die gemeinschaftliche Leitung, die normalerweise der Zuführung der Gase vom Absperrventil zum Motor dient, und werden an einer geeigneten Stelle durch ein weiteres in die Gasleitung eingebautes Sicher- *5 heiitsventil ins Freie abgeführt.The present invention is now a valve body which Sicherheks- 5 * and shut-off valve in an opening can be open, but both valves are formed separately in a conventional manner in which; and connected in parallel. If that .; When the safety valve comes into operation, the gases flow into the common line, which normally serves to supply the gases from the shut-off valve to the engine, and are discharged into the open at a suitable point through another safety valve built into the gas line.
Die beiliegende Abbildung zeigt den Ventilkörper α mit dem normalen Absperrventil b und dem im vorliegenden Fall aus einer Reiß^ scheibe bestehenden selbsttätigen Sicherheitorgan c. Normalerweise strömen die Gase aus der Zuleitung d durch das geöffnete Absperrventil b in die Ableitung e. Tritt das Sicherheitsorgan bei unzulässigem Überdruck in Tätigkeit, so geht der Gasweg durch die "/5 zerreißende Reißscheibe c ebenfalls nach e. Eine gemeinsame Rohrleitung / führt sodann '/. das Gas in beiden Fällen aus dem Bereich der Druckfiaschen fort.The accompanying illustration shows the valve body α with the normal shut-off valve b and the automatic safety device c, which in the present case consists of a tear disk. The gases normally flow from the supply line d through the open shut-off valve b into the discharge line e. If the safety device comes into action in the event of an impermissible overpressure , the gas path goes through the tearing disc c also to e. A common pipeline / then leads' /. The gas in both cases continues from the area of the pressure bottle.
