Das vorliegende Absperrventil für Gas- und Oelleitungen sperrt den Gas- bezw. Oelzuflufs selbstthätig ab, sobald die Temperatur der Umgebung bis auf eine bestimmte Höhe gestiegen ist. Es besteht aus einem Ventilkörper mit kegelig zulaufendem Ventilsitz, abnehmbarer Boden- ynd Kopfschraube und einem Ventilkegel, dessen Spindel durch die Kopfschraube hindurchgeht und oberhalb der Kopfschraube von einem Knopf oder Steg aus leicht schmelzbarem Metall gehalten wird. Sobald die das ^Ventil umgebende Temperatur eine gewisse Höhe erreicht hat, schmilzt der Knopf oder Steg, das Ventil wird unter der Wirkung einer Feder auf seinen Sitz geprefst und sperrt dadurch den Gas- oder Oelzuflufs ab.The present shut-off valve for gas and oil lines blocks the gas resp. Oil influx automatically decreases as soon as the temperature of the environment has risen to a certain level is. It consists of a valve body with a tapered valve seat, removable Boden- ynd head screw and a valve cone, its spindle through the head screw passes through and above the cap screw from a button or bar made of easily meltable Metal is held. As soon as the temperature surrounding the valve has reached a certain Has reached height, the button or web melts, the valve is under the action of a The spring is pressed onto its seat and thereby blocks the gas or oil supply.
Das Ventil ist in zwei verschiedenen Ausführungen gezeichnet. Das Ventilgehäuse A, Fig. ι und 2, ist mit einem kegelig zulaufenden Ventilsitz B versehen, in welchen der Ventilkegel C hineinpafst. Letzterer ist in den Sitz B eingeschliffen. Das Ventilgehäuse A ist unterhalb -B durch eine Schraubenkappe B1 geschlossen, während der oberhalb B befindliche Stutzen A1 durch eine Kappe D geschlossen ist, durch welche der Ventilstift C1 des Ventils C hindurchgeht. Auf der Kappe D befindet sich ein Bock E, welcher einem Knopf F aus leicht schmelzbarem Metall als Auflager dient. Der Knopf F ist von dem Bock E durch eine Scheibe F1 aus Hartgummi oder einem anderen, die Wärme nicht leitenden Stoff geschützt, um das Schmelzen des Knopfes zu bewirken, sobald die umgebende Temperatur auf den Schmelzpunkt des Knopfes gestiegen ist, ohne dafs das Schmelzen durch den Einflufs des kälteren Metalles des Bockes E verzögert würde.The valve is drawn in two different versions. The valve housing A, Fig. 1 and 2, is provided with a tapered valve seat B , into which the valve cone C fits. The latter is ground into seat B. The valve housing A is closed below -B by a screw cap B 1 , while the connecting piece A 1 located above B is closed by a cap D through which the valve pin C 1 of the valve C passes. On the cap D there is a bracket E, which serves as a support for a button F made of easily meltable metal. The button F is protected from the bracket E by a disk F 1 made of hard rubber or some other material that does not conduct heat, in order to cause the button to melt as soon as the ambient temperature has risen to the melting point of the button without melting would be delayed by the influence of the colder metal of the bracket E.
Durch ein Loch des Knopfes F und die ringförmige Schutzscheibe F1 und den oberen ringförmigen Theil des Bockes E hindurch geht eine Schraube f, welche mit ihrem unteren Ende in den Ventilstift C1 eingeschraubt ist und mit ihrem Kopf auf dem Knopf F liegt. Wenn nun die Temperatur auf den Schmelzpunkt des Knopfes F gestiegen ist, schmilzt der Knopf, und der Ventilkegel C fällt theils durch seine eigene Schwere, theils durch die Wirkung der Feder C2, welche zwischen der Unterlegscheibe g der Kappe D und dem Boden des hohlen Ventilkegels C angeordnet ist, nach unten. Der Kegel C fällt auf den Ventilsitz B, sperrt dadurch den Gasoder Oelzuflufs ab und verhütet auf diese Weise z. B. eine weitere Verbreitung des Feuers durch den Austritt von Gas oder OeI. A screw f, which is screwed with its lower end into the valve pin C 1 and lies with its head on the button F , passes through a hole in the button F and the annular protective disk F 1 and the upper annular part of the bracket E. When the temperature has risen to the melting point of button F , the button melts, and the valve cone C falls partly due to its own weight, partly due to the action of the spring C 2 , which lies between the washer g of the cap D and the bottom of the hollow Valve cone C is arranged downward. The cone C falls on the valve seat B, thereby shutting off the gas or oil supply and in this way prevents z. B. a further spread of the fire through the escape of gas or oil.
Um den Ventilkegel wieder in seine frühere gehobene Lage zurück zu bringen, schraubt man die untere Kappe -B1 ab, hebt C in die Höhe, setzt aufi7"1 einen neuen Knopf F und stellt die Verbindung zwischen diesem und dem Kegel C durch die Schraube f her.In order to bring the valve cone back to its previous raised position, unscrew the lower cap -B 1 , lift C up , put a new button F on i 7 " 1 and establish the connection between this and the cone C through the Screw f her.
In Fig. 3 und 4 ist der Knopf F der vorigen Construction durch einen Steg ,F2 ersetzt, welcher durch einen Schlitz des Ventilstiftes C1 hindurchgesteckt ist und auf einem auf der Kappe D angeordneten Wärmeschutzring f2 liegt. Auch hier fällt der Ventilkegel C herab,In FIGS. 3 and 4, the button F of the previous construction is replaced by a web, F 2 , which is inserted through a slot in the valve pin C 1 and lies on a heat protection ring f 2 arranged on the cap D. Here, too, valve cone C falls down,
sobald die umgebende Temperatur auf den Schmelzpunkt des Steges F2 gestiegen ist.as soon as the surrounding temperature has risen to the melting point of the web F 2.
Claims (1)
An dem unter i. gekennzeichneten Ventil:i. A valve, consisting of the valve housing A with a tapered seat B, the valve cone C, the pin C 1 of which goes through the upper, removable cap -D, and an easily meltable button F or web F 2 , which the valve cone C on the cap D assists and drops automatically when the temperature has risen to the melting point of the button.
At the under i. marked valve:
Ventils zu beeinflussen.b) the arrangement of the heat protection ring F 1 as a washer for the easily meltable button F or bar F 2 , so that the melting point of the latter is not caused by the metal
To influence the valve.
