Description

KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Das Sicherheitsventil α ist mit der Scheibe b verbunden, welche einen zwischen beiden liegenden Raum c begrenzt und so angebracht ist, dafs der zum Ventil α gelangende Dampf an ihr vorbeigeht. Bei durch Drucküberschreitung hervorgerufenem Heben des Sicherheitsventiles entsteht ein Druckunterschied ober- und unterhalb der Scheibe, wodurch dieselbe nach oben gedrängt wird; der mit hohem Druck nach oben gehende Dampf wirkt bei seiner Strömung auf die Scheibe b, so dafs ein besonders hoher Hub des Sicherheitsventiles herbeigeführt wird.The safety valve α is connected to the disk b , which delimits a space c between the two and is attached in such a way that the steam reaching the valve α passes it. When the safety valve is raised due to the pressure being exceeded, a pressure difference arises above and below the disc, which pushes the disc upwards; the steam, which goes upwards at high pressure, acts on disk b as it flows, so that a particularly high lift of the safety valve is brought about.

Claims (1)

Pa tent-Anspruch:Patent claim: Ein Sicherheitsventil mit einer auf der Druckseite an demselben angebrachten Scheibe b, welche sich in einem seitlich abgeschlossenen Raum c in geringer Entfernung gegenüber der Durchströmöffnung für den Dampf oder dergleichen befindet und deren Durchmesser dem jener Oeffhung ungefähr gleich ist. A safety valve with a disc b attached to it on the pressure side, which is located in a laterally closed space c at a short distance from the through-flow opening for the steam or the like and whose diameter is approximately the same as that of that opening.
