Description
Die bei Reduzierventilen, Sicherheitsventilen usw. allgemein verwendeten Gummimembranen gestatten infolge der geringen Festigkeit des Gummis nur eine geringe Belastung der Membran. Metallmembranen, wie sie für hohe Belastungen verwendet werden, haben dagegen den Nachteil, daß sie außerordentlich unelastisch sind, sich also auch bei hoher Belastung nur wenig durchbiegen.The rubber diaphragms commonly used in reducing valves, safety valves, etc. allow only a low load on the membrane due to the low strength of the rubber. Metal diaphragms, like they are used for high loads, however, have the disadvantage that they are extremely are inelastic, so they only bend slightly even under high loads.
Vorliegende Erfindung zeigt eine Membran, welche die Vorteile einer Gummi- und einer Metallmembran in sich vereinigt, also hohe Elastizität und hohe Widerstandskraft.The present invention shows a membrane which has the advantages of a rubber and united by a metal membrane, i.e. high elasticity and high resistance.
Im wesentlichen beruht' die Erfindung darauf, daß die Membran aus einer elastischen dichten Platte und einer bzw." mehreren versetzt übereinandergelagerten Rosettenfedern gebildet ist, die die Membran elastisch abstützen. Essentially, the invention is based on the fact that the membrane consists of an elastic dense plate and one or more staggered rosette springs is formed, which elastically support the membrane.
Das im folgenden näher beschriebene und auf beiliegender Zeichnung dargestellte Ausführungsbeispiel soll die Erfindung erläutern.The exemplary embodiment described in more detail below and shown in the accompanying drawing is intended to explain the invention.
Abb. ι zeigt eine der Erfindungsidee entsprechende
Membran im Schnitt.
a5 Abb. 2 zeigt eine Rosettenfeder im Grundriß. Fig. Ι shows a membrane corresponding to the idea of the invention in section.
a 5 Fig. 2 shows a rosette spring in plan.
Die Membran Abb. ι ist entsprechend der Erfindung aus einer hochelastischen Platte (Gummi o. dgl.) α und zwei Rosettenfedern b gebildet. Die Rosettenfedern b werden zweckmäßig so übereinander angeordnet, daß die Lappen c der einen Feder die Ausschnitte d der anderen Feder überdecken. Die Anordnung zweier Rosettenfedern übereinander ist besonders zweckmäßig, da dadurch die Platte α vollständig abgedeckt wird (der noch offene zentrale Teil, welcher durch die Federn nicht erfaßt wird, kann durch ein besonderes Plättchen e zwischen Federn und Platte α abgedeckt werden). Die Platte a nimmt also bei dieser Anordnung nicht den Druck auf, sondern hat lediglich den Zweck abzudichten, während die Rosettenfedern dem Druck auf die Membran den nötigen Widerstand entgegensetzen. Gegenüber einer starren Metallmembran hat eine Rosettenfeder entsprechend der Erfindung den Vorteil, daß die in einer geschlossenen Metallmembran auftretenden Zugspannungen fortfallen. Die Verbindung einer dichten Platte mit Rosetten- 5<> federn ergibt also eine auch für hohe Belastungen widerstandsfähige und elastische Membran.The membrane Fig. Ι is formed according to the invention from a highly elastic plate (rubber or the like) α and two rosette springs b . The rosette springs b are expediently arranged one above the other so that the tabs c of one spring cover the cutouts d of the other spring. The arrangement of two rosette springs on top of one another is particularly useful, as it completely covers the plate α (the central part which is still open and which is not covered by the springs can be covered by a special plate e between the springs and plate α ). The plate a does not take up the pressure in this arrangement, but only has the purpose of sealing, while the rosette springs oppose the necessary resistance to the pressure on the membrane. Compared to a rigid metal membrane, a rosette spring according to the invention has the advantage that the tensile stresses occurring in a closed metal membrane are eliminated. The connection of a tight plate with rosette springs results in a membrane that is resistant and elastic even for high loads.
