Description

Für die Sicherung von Druckbehältern werden vielfach Reißscheiben verwendet, die bei Überschreitung eines bestimmten Drucks reißen, so daß durch Abströmen des Druckmittels der Druck absinkt. Druck .Tear disks are often used to secure pressure vessels used, which tear when a certain pressure is exceeded, so that by flowing off of the pressure medium the pressure drops. Pressure .

Derartige Reißscheiben können entweder aus einer festen ebenen Platte oder aus einem weichen Werkstoff bestehen, der unter dem Druck eine Kugelkalotte bildet. Der Werkstoff wird dabei bis nahe an die Grenze belastet und ist darum außerordentlich empfindlich gegen Einflüsse, z. B. spielt die Stärke, mit der die Reißscheibe eingespannt ist, eine Rolle. Je nach der Stärke der Anpressung wird der Reißdruck um etwa 20 °/o schwanken.Such tear disks can either consist of a solid flat plate or consist of a soft material that forms a spherical cap under the pressure forms. The material is loaded almost to the limit and is therefore extraordinary sensitive to influences, e.g. B. plays the strength with which the tear disk is clamped is a role. Depending on the strength of the pressure, the tear pressure is around 20 ° / o fluctuate.

Die Erfindung bezweckt die Beseitigung dieses Unsicherheitsfaktors: Nach der Erfindung wird die Einspannbohrung größer gehalten als der Durchmesser der beanspruchten Fläche der Reißscheibe. Ferner wird auf der Druckseite eine nachgiebige Ringscheibe eingelegt, die den Anpreßdruck der Einspannung nur so weit auf das eingeklemmte Material der Reißscheibe überträgt, wie die Einspannung selbst reicht. Dadurch wird jede Überbeanspruchung der Reißscheibe an der Kante vermieden.The invention aims to eliminate this uncertainty factor: According to the invention, the clamping bore is kept larger than the diameter the stressed area of the tear disk. Furthermore, on the pressure side there is a flexible one Ring washer inserted, which the contact pressure of the clamping only so far on the clamped Material of the tear disk transfers as the restraint itself is sufficient. This will any overstressing of the tear disk at the edge is avoided.

In der Zeichnung ist ein. Ausführungsbeispiel des Erfindungsgegenstandes in einem senkrechten Schnitt dargestellt.In the drawing is a. Embodiment of the subject matter of the invention shown in a vertical section.

Als Träger der Reißscheibe i dient eine Kapsel 2, die auf einem Absatz 3 in der abgesetzten Bohrung eines Rohrstutzens 4 liegt und durch eine in den Stutzen eingeschraubte Büchse 5 festgespannt ist. Auf der Druckseite wird die Reißscheibe in der Kapsel durch eine etwas nachgiebige Ringscheibe 6 gehalten. DerDurchmesser derRingscheibenöffnung entspricht etwa dem Durchmesser a der Kapselbohrung. Der Durchmesser a ist kleiner als die Einspannbohrung b der Kapsel. Mit 7 ist .ein auf dem Absatz 3 liegender Dichtring und mit 8 eine in der Kapsel e festgeklemmte Schutzscheibe bezeichnet.A capsule 2, which is on a shoulder, serves as the carrier of the tear disk i 3 lies in the remote bore of a pipe socket 4 and through one in the socket screwed-in sleeve 5 is clamped. The tear disk is on the pressure side held in the capsule by a somewhat flexible washer 6. The diameter the washer opening corresponds approximately to the diameter a of the capsule bore. Of the Diameter a is smaller than the clamping hole b of the capsule. At 7 there is a the paragraph 3 lying sealing ring and with 8 a clamped in the capsule e protective disk designated.
