KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Vorrichtung bezweckt, ein Verbrennen der Arbeiter durch den aus einem gebrochenen Rohr strömenden Dampf zu verhüten, und besteht aus einem Ventilgehäuse A, welches an das Absperrventilgehäuse B der Dampfleitung C angeschlossen ist und entweder mit dem Dampfdom D eines Kessels oder dem Dampfsammler einer Kesselbatterie in Verbindung steht.The device aims to prevent the workers from being burned by the steam flowing out of a broken pipe and consists of a valve housing A, which is connected to the shut-off valve housing B of the steam line C and either with the steam dome D of a boiler or the steam collector of a boiler battery Connection. Das Ventilgehäuse A trägt einen cylindrischen Aufsatz G mit darin sich dampfdicht bewegendem Kolben E, welcher durch eine Stange mit dem Ventilkegel H verbunden ist. Ueber dem Kolben E mündet ein mit Ventil versehenes schmiedeisernes Rohr K, welches zu dem Dom des Kessels oder dem Dampfsammler führt, während unter dem Kolben ein mit Ventil versehenes Rohr L mündet, welches zu der Rohrleitung C führt. Die Mündung des Rohres L im Aufsatz G liegt so, dafs der Kolben in der tiefsten Stellung dieselbe vollständig verschliefst.The valve housing A carries a cylindrical attachment G with a piston E which moves in a steam-tight manner and which is connected to the valve cone H by a rod. Above the piston E opens a valve-provided wrought-iron pipe K, which leads to the dome of the boiler or the steam collector, while a valve L , which leads to the pipeline C, opens under the piston. The mouth of the tube L in the attachment G is so that the piston closes it completely in the lowest position. Sobald infolge eines Bruches in der Dampfleitung Dampf aus dem Rohr C tritt, treibt der in dem Rohr K befindliche, Kesselspannung besitzende Dampf den Kolben E abwärts, wodurch das Ventil H geschlossen wird, so dafs der Dampf aus dem Dampfkessel zur Rohrleitung nicht strömen kann. Der Kolben E hat eine um so viel gröfsere Fläche als der Ventilkegel H, dafs der Dampf des Rohres K im Stande ist, das Ventil zu schliefsen und die Feder O, welche dazu dient, das Gewicht des Ventilkegels mit Stange auszugleichen, zusammenzudrücken und in dieser Lage zu erhalten, bis das Absperrventil B geschlossen ist.As soon as steam emerges from pipe C as a result of a break in the steam pipe, the steam in the pipe K, which has boiler voltage, drives piston E downwards, whereby valve H is closed so that the steam cannot flow from the steam boiler to the pipe. The area of the piston E is so much larger than that of the valve cone H that the steam from the tube K is able to close the valve and the spring O, which serves to counterbalance the weight of the valve cone with the rod, is able to compress and in this Position until the shut-off valve B is closed. Patent-Anspruch:Patent claim: Ein in die Dampfleitung eingeschaltetes Ventil, welches von einem Dampf kolben bethätigt wird, dessen Cylinder einerseits mit dem Dampfkessel, andererseits mit der Dampfleitung derart in Verbindung steht, dafs bei einem Bruch in der Leitung der Kolben das Ventil schliefst.A valve connected to the steam line, which is actuated by a steam piston whose cylinder on the one hand with the steam boiler, on the other hand with the steam pipe is in such a connection that in the event of a rupture in the line of the piston the valve slept.
