Sicherheitsventil mit Lenkerführung für den Ventilträger.Safety valve with handlebar guide for the valve carrier.

Patentiert im Deutschen Reiche vom 25. Dezember 1923 ab.Patented in the German Empire on December 25, 1923.

Für diese Anmeldung ist gemäß dem Unionsvertrage vom 2. Juni 1911 die Priorität auf Grund der Anmeldung in der Schweiz vom 3. Januar 1923 beansprucht.According to the Union Treaty of June 2, 1911, priority is due to this application of the registration in Switzerland of January 3, 1923.

Sicherheitsventile an Wassergefäßen leiden unter dem Nachteil, daß die Führung des Ventilkegels, d.i. die Ventilspindel, sich; mit der Zeit mit Kalkablagerangen oder Sandkömern versetzt. Dadurch öffnen oder schließen die Ventile nicht mehr sicher. Außerdem entstehen. z.B. bei Ventilen mit Druckfedern unerwünschte Reibungen durch schiefen Druck auf den Ventilkegel, so daß aus diesem Grunde die Wirkungsweise ebenfalls unsicher erfolgt. Zur Verhütung dieser Übelstände hat man daher schon vorgeschlagen, bei solchen Ventilen den Ventilträger mit einem führenden Lenker zu versehen. Diese einseitige Lenkeranordnung am Ventilkörper gibt aber auch nicht eine einwandfreie Führung für denselben.Safety valves on water vessels suffer from the disadvantage that the leadership of the Valve cone, i.e. the valve stem, itself; over time with lime deposits or sand grains offset. As a result, the valves no longer open or close safely. aside from that develop. E.g. in the case of valves with compression springs, undesired friction caused by leaning Pressure on the valve cone, so that for this reason the mode of operation is also unsafe he follows. In order to prevent these inconveniences, it has therefore already been proposed to include the valve carrier in such valves to provide a leading handlebar. This unilateral link arrangement on the valve body but also does not give impeccable guidance for the same.

Die Erfindung betrifft nun ein Sicherheits-The invention now relates to a security

ventil mit Lenkerführung für den Ventilträger, welches sich durch die Anordnung zweier ein Gelenkparallelogramm bildender Lenker kennzeichnet,'so- daß es vollständig reibungsfrei arbeitet und daher keinerlei- Aufsicht oder Wartung erfordert. Diese Eigenschaften sind z. B. für unter Druck stehende elektrische Heißwasserspeicher im Haushalte von großer Wichtigkeit.valve with handlebar guide for the valve carrier, which is achieved by the arrangement of two a link forming an articulated parallelogram characterizes' so that it is completely frictionless works and therefore does not require any supervision or maintenance. These properties are z. B. for pressurized electrical hot water tanks in households of great Importance.

ίο In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Mit α ist ein Wassergefäß, welches gegen Überdruck geschützt werden soll, bezeichnet. Am Ventil selbst bezeichnet b den Ventilköxper, c den Druckstutzen und d den Abwasserstutzen, e ist die Abschlußmutter mit einer aufgebauten Stange k\ f ist der Ventilteller mit einer Dichtungsauflage g. An dem Ventilteller / sitzt der Stift k, welcher gelenkig mit der Spindel / verbunden ist. t und m sind Führungslenker, die einerseits mit der Stange k, anderseits mit der Spindel/ gelenkig verbunden sind und so ein Gelenkparallelogramm bilden, η ist eine Zugfeder, ο eine Regulierschraube und ρ eine Reguliermutter zur Regelung der Spannung der Feder n. ίο In the drawing, an embodiment of the subject of the invention is shown. A water vessel, which is to be protected against overpressure, is designated with α. On the valve itself, b denotes the valve body, c the pressure connection and d the waste water connection, e is the locking nut with a built-up rod, k \ f is the valve disk with a sealing pad g. The pin k, which is articulated to the spindle /, is seated on the valve plate /. t and m are guide links that are articulated on the one hand to the rod k and on the other hand to the spindle / and thus form a joint parallelogram, η is a tension spring, ο a regulating screw and ρ a regulating nut to regulate the tension of the spring n.

Sobald der Druck im Gefäß d den Ventilteller / hebt, verschwenken sich die Lenker I und m um ihren Drehpunkt an der Stange k und gelangen mit dem Ventilteller / und der Spindel / in die strichpunktiert gezeichnete Lage. Die Spindelachse ist annähernd parallel zu ihrer Ruhelage verschoben worden. Die Öffnung in der Ventilmut- ter für den Durchgang der Ventilspindel/ ist dabei so groß, daß dieselbe genügend Spiel hat und nicht mit ihr in Berührung kommt. Hier liegt eben der Vorteil der vorliegenden Einrichtung, denn es ist wichtig, daß die Ventilspindel nicht in einer Gleitführung, etwa in einer Stopfbüchse, geführt werde, damit nicht der eingangs genannte Übelstand des Sperrens oder Versetzens der Ventilspindel eintrete.As soon as the pressure in the vessel d lifts the valve disk /, the links I and m pivot around their pivot point on the rod k and, with the valve disk / and the spindle /, move into the position shown in dash-dotted lines. The spindle axis has been moved approximately parallel to its rest position. The opening in the valve nut for the passage of the valve spindle / is so large that it has enough play and does not come into contact with it. This is the advantage of the present device, because it is important that the valve spindle is not guided in a sliding guide, for example in a stuffing box, so that the aforementioned inconvenience of locking or relocating the valve spindle does not occur.

Die Zugfeder λ könnte natürlich auch durch eine Druckfeder ersetzt werden, welche z. B. von oben auf die Ventilspindel drücken würde.The tension spring λ could of course also be replaced by a compression spring, which z. B. would press from above on the valve spindle.
