Description
Gegenstand der vorliegenden Erfindung ist ein Sicherheitsventil mit Druckhebel oder Federbelastung, insbesondere für hohe Flüssigkeits- oder Gasdrücke in Heizkesseln, Badeöfen, Boilern oder Rohrleitungen usw., bei welchem das Wesen darin besteht, daß im Ventilgehäuse ein Steigrohr für das auf Druck gebrachte flüssige oder gasförmige Medium von niedriger oder erhöhter Temperatur angeordnet- ist, dessen Austrittsmündung eine gummiartige Membran verschließt, die von einem Gewichtshebel belastet ist, wobei das bei Überdruck aus dem Steigrohr strömende flüssige oder gasförmige Medium durch einen das Steigrohr umschließenden, im Ventilgehäuse . angeordneten mantelförmigen Hohlraum, dessen lichtes Querschnittsmaß an seiner engsten Stelle demjenigen des zylindrischen Steigrohrs entspricht, ausströmt.The present invention is a safety valve with Pressure lever or spring loading, especially for high liquid or gas pressures in boilers, bath stoves, boilers or pipes, etc., in which the essence consists in the fact that a riser pipe for the pressurized liquid in the valve housing or gaseous medium of low or elevated temperature is arranged, its A rubber-like membrane closes the outlet mouth, which is controlled by a weight lever is loaded, with the liquid or flowing out of the riser pipe at overpressure gaseous medium through a pipe that surrounds the riser in the valve housing. arranged shell-shaped cavity, the clear cross-sectional dimension at its narrowest point corresponds to that of the cylindrical riser pipe, flows out.
Der Gewichtsarm ist an dem Deckel des Ventilgehäuses angelenkt, der zugleich die Abdichtung des letzteren bewirkt, indem er auf die ringförmige Sitzfläche der Membran preßt. Der Deckel mit dem Gewichtsarm ist um die Achse des Ventils drehbar.The weight arm is hinged to the cover of the valve housing, the at the same time the sealing of the latter is effected by placing it on the annular seat the membrane presses. The cover with the weight arm can be rotated around the axis of the valve.
Die Zeichnung veranschaulicht den Erfindungsgegenstand in einer beispielsweisen Ausführungsform; es zeigt Fig. i einen senkrechten Schnitt durch das Ventil und Fig. 2 eine Teilzeichnung zu Fig. i.The drawing illustrates the subject matter of the invention in an exemplary manner Embodiment; It shows Fig. i a vertical section through the valve and FIG. 2 shows a partial drawing of FIG.
Das Sicherheitsventil besteht aus dem Ventilgehäuse i, welches durch einen Deckel 2 mittels einer Überwurfmutter 3 verschlossen ist. An dem Deckel 2 ist der Belastungshebel 4 mittels der Tragarme 5 schwenkbar angebracht und trägt einen Stempel 6, der auf die gummiartige Membran 7 drückt. Dabei wird die Mündung des unter Druck stehenden Innenraumes des zylindrischen Steigrohres 8 verschlossen gehalten. Die Membran 7 ruht auf einer oberen Ringfläche 9 des Ventilgehäuses i, die versenkt ist. Diese Versenkung ist dazu benutzt;. einerseits der Membran eine unverschiebbare, zentrische Lage bei Lösung des Deckels 2 zu sichern und andererseits diesem mittels seines zylindrischen Ansatzes io eine zentrische Führung zu geben, die die Verschließung des Ventilgehäuses mit der Überwurfmutter 3 wesentlich erleichtert. Das lichte Querschnittsmaß des Steigrohres 8 entspricht dem ringförmigen Querschnitt des Hohlraumes zwischen Steigrohr 8 und Ventilgehäuse i an der engsten Stelle, so daß keine Stauung des unter hohem Druck austretenden Flüssigkeits- oder Gasstromes eintreten kann.The safety valve consists of the valve housing i, which is closed by a cover 2 by means of a union nut 3. The loading lever 4 is pivotably attached to the cover 2 by means of the support arms 5 and carries a stamp 6 which presses on the rubber-like membrane 7. The mouth of the pressurized interior of the cylindrical riser pipe 8 is kept closed. The membrane 7 rests on an upper annular surface 9 of the valve housing i, which is sunk. This sinking is used for this. on the one hand to secure a non-displaceable, central position of the membrane when the cover 2 is released and on the other hand to give it a central guidance by means of its cylindrical extension, which makes it much easier to close the valve housing with the union nut 3. The clear cross-sectional dimension of the riser pipe 8 corresponds to the annular cross-section of the cavity between the riser pipe 8 and valve housing i at the narrowest point, so that no stagnation of the liquid or gas flow exiting under high pressure can occur.
Infolge der zentrischen Führung des Deckels 2 kann bei geringer Lösung der Überwurfmutter 3 der Belastungshebel 4 in irgendeine bestimmte Winkelstellung innerhalb 36o' gebracht werden.As a result of the central guidance of the cover 2, with a low solution the union nut 3 of the loading lever 4 in any specific angular position be brought within 36o '.
Das Sicherheitsventil sichert einen unbedingt dichten Abschluß. Die beweglichen Metallteile kommen mit der Flüssigkeit oder dem Gas nicht in Berührung, so daß keine Oxydation derselben erfolgen kann, womit die Wirkungsweise des Ventils auch bei nicht unterworfener Überwachung gesichert ist.The safety valve ensures an absolutely tight seal. the moving metal parts do not come into contact with the liquid or gas, so that no oxidation of the same can take place, with which the mode of operation of the valve is secured even if it is not subject to supervision.
Die Auswechselung der Membran ist ohne Abnahme des Ventilgehäuses vom Sicherungsobjekt leicht ausführbar.The membrane can be replaced without removing the valve housing easily executable by the backup object.
Es versteht sich, daß an Stelle des Gewichtshebels mit Gewicht auch die Ausführung mit Druckfedern möglich ist.It goes without saying that in place of the weight lever with weight also the execution with compression springs is possible.
