Ventilen.Valves.

Um das Umherspritzen von heifsem Wasser und Dampf nach einem Bruch des Wasserstandsglases zu verhindern, ist folgende Vorrichtung getroffen:About the splashing of hot water and steam after breaking the water level glass To prevent this, the following device is in place:

Zwischen den Abschlufshähnen A A\ die das Wasserstandsglas gegen den Kessel abschliefsen, und dem ersteren sind Ventilgehäuse C eingeschaltet, deren Durchgänge sich schliefsen, sobald ein Ueberdruck von unten nach oben wirkt, die aber im anderen Falle geöffnet sind. Da nun Wasser und Dampf bei gewöhnlichem Betrieb des Kessels durch diese Ventile strömen müssen, so schliefsen sich dieselben sofort nach Bruch des Glases, durch den Druck im Kessel gehoben, und verhindern jeden Austritt von Wasser und Dampf, beseitigen also jede Gefahr für den Wärter. Valve housings C are switched on between the shut-off cocks AA \, which close the water level glass against the boiler, and the former, the passages of which close as soon as an overpressure acts from below upwards, but which are open in the other case. Since water and steam have to flow through these valves during normal operation of the boiler, they close immediately after breakage of the glass, raised by the pressure in the boiler, and prevent any escape of water and steam, thus eliminating any danger to the keeper.

Dieser Zweck, zugleich aber auch eine leichte Reinigung und dadurch sichere Wirkung . des ganzen Apparates, wird durch folgende Construction erreicht:This purpose, but at the same time easy cleaning and therefore safe effect. of whole apparatus, is achieved by the following construction:

Die Hähne A A1, von denen der obere der leichteren Zugänglichkeit wegen einen Handgriff von oben, der untere einen solchen von unten hat, haben zunächst zwei Bohrungen b b1 einander gegenüber, um nach Lösung der Schrauben BB1 ein Durchstofsen durch den Kanal α bis in den Kessel zu ermöglichen. Um einen Viertelkreis versetzt, findet sich in demselben Querschnitt des Kükens, Fig. 3, eine ' Oeffnung c. Wenn c vor den Kanal a gestellt ist, wie in Fig. 1 gezeichnet, tritt gleichzeitig die Oeffnung d, Fig. 4, vor die Einmündung e in das Ventilgehäuse C. Wasser und Dampf gelangen dann durch das Ventil D in das Wasserstandsglas, so dafs dieses richtig functionirt. Um dieses beim ersten Anlassen zu erlangen, braucht man nur von unten oder oben durch die Oefmungen b b1 direct den Druck in das Glas zu lassen. Sobald aber der Druck im Glase aufhört, also beim Zerspringen desselben, schliefsen sich sofort beide Ventile und verhindern jeden Austritt.The taps AA 1 , of which the upper one has a handle from above for easier access and the lower one from below, initially have two holes bb 1 opposite each other to allow a passage through the channel α to in after loosening the screws BB 1 to enable the boiler. Offset by a quarter of a circle, there is an opening c in the same cross section of the plug, FIG. 3. If c is placed in front of the channel a , as shown in Fig. 1, the opening d, Fig. 4, occurs at the same time in front of the junction e in the valve housing C. Water and steam then pass through the valve D into the water level glass, so that this works properly. In order to achieve this when starting the glass for the first time, one only needs to let the pressure directly into the glass from below or above through the openings bb 1. But as soon as the pressure in the glass ceases, i.e. when it bursts, both valves close immediately and prevent any leakage.

Um nun ein unbedingt sicheres Arbeiten der Ventile zu erreichen, ist es nothwendig, dieselben durch Durchblasen von Ablagerungen von Schlamm und Schmutztheilen zeitweise zu reinigen. Da dies durch Oeffhen des Abflufshahnes F nicht bewirkt werden kann, weil sich dabei die Ventile schliefsen, so sind noch die kleinen Hähne E angebracht. Dreht man einen der Hähne A oder A1, so dafs die Oeffnung α abgeschlossen ist, und stellt die Oeffnung f vor den Kanal e, öffnet gleichzeitig den Ausströmungshahn E, wie Fig. 2 gezeichnet, so tritt Dampf oder Wrasser durch Glas und Ventilgehäuse und strömt durch E und die Bohrung g der Hähne A A1 nach unten aus, so dafs jeder Schmutz beseitigt werden mufs.In order to achieve an absolutely safe operation of the valves, it is necessary to clean them from time to time by blowing through them with deposits of sludge and debris. Since this cannot be done by opening the drain cock F , because the valves close, the small cocks E are still attached. By turning one of the taps A or A 1; so that the opening is completed α, and adjusts the opening f before the channel e, simultaneously opens the Ausströmungshahn E, as shown in FIG. 2 drawn, as occurs steam or W r ater through glass and Valve housing and flows out through E and the bore g of the taps AA 1 downwards, so that any dirt must be removed.

Patent-Anspruch:Patent claim: An einem beim Bruch des Glases selbstthätig schliefsenden Wasserstandszeiger: die Wiederöffnung des durch einseitige Belastung geschlossenen Ventiles durch Herstellung der Verbindung des Kesselausflufskanales mit einem oberhalb des Ventiles mündenden Nebenkanal D in Verbindung mit der Durchblasevorrichtung mittels Communication der Kanäle e und g durch die Hahnbohrung f. On a water level indicator that closes automatically when the glass breaks: the reopening of the valve, which has been closed by one-sided loading, by establishing the connection between the boiler outlet channel and a secondary channel D opening above the valve in connection with the blow-through device by means of communication between channels e and g through the tap hole f.
