Description
Auf Grund von Erfahrungen, die im Betrieb der elektrischen Heißwasservorrichtungen gemacht wurden, muß nicht nur im Einlauf dieser Heißwasservorrichtungen ein 1Sicherheitsventil angeordnet sein, sondern auch die zu den Verbrauchsstellen führende Heißwasserleitung muß .gegen das Auftreten schädlicher Drücke gesichert sein. Diese Vorschrift wird durch das Doppelsicherheitsventil nach der Erfindung in einer platz- und werkstoffsparenden Weise :gelöst, indem die beiden Ventilsitze an den Stirnflächen seines kurzen Rohrstutzens angeordnet sind, von dem der Ablaufstutzen ins Freie rechtwinklig abzweigt, wobei eine Wand in der 'Symmetrieebene zwischen den beiden Ventilsitzen die beiden. Teile des Gehäuses voneinander trennt, von denen der .eine mit dem Einlauf und der andere mit dem Ablauf zu den Verbrauchsstellen verbunden ist, und wobei zwei Membranen als Verschlußstücke dienen, die mit ihrem Rand zwischen dem-vom Wasser bespülten Gehäusehauptteil und je einer eirischraubbaren Kappe eingespannt sind, in der die einstellbaren Belastungsfedern mit ihren Spannvorrichtungen untergebracht sind.Based on experience gained in the operation of electric hot water devices a safety valve must not only be installed in the inlet of these hot water devices be arranged, but also the hot water pipe leading to the consumption points must be secured against the occurrence of harmful pressures. This rule will by the double safety valve according to the invention in a space and material-saving Way: solved by attaching the two valve seats to the end faces of its short pipe socket are arranged, from which the outlet nozzle branches off into the open at right angles, wherein a wall in the 'plane of symmetry between the two valve seats the two. Parts the housing separates from each other, of which the .one with the inlet and the other is connected to the drain to the consumption points, and with two membranes serve as locking pieces, the rinsed with their edge between the water Housing main part and each one egg screw cap are clamped in which the adjustable loading springs are housed with their clamping devices.
Die Erfindung wird an Hand der Zeichnung an einem Doppelventil erläutert, das in der Zu- und Abführungsleitung eines Heißwasserboilers eingebaut ist. Fig. i, z und 3 zeigen dasselbe Ventil in verschiedenen Ansichten.The invention is explained using the drawing on a double valve, which is installed in the supply and discharge line of a hot water boiler. Fig. i, z and 3 show the same valve in different views.
Das 'Sicherheitsdoppelventil besteht aus dem Ventilgehänsehauptteil 4 mit dem kurzen Rohrstutzen 3o, dessen beide 'Stirnenden als Ventilsitze dienen und von dem der Ablaufstutzen 7 ins Freie abzweigt. Eine Wand 3a trennt die beiden Räume 16 -und 17 voneinander, von denen der eine mixt dem Kaltwassereinlauf i i, der andere mit dem zu den Verbraucherstellen führenden Rohr 9 verbunden ist, wie Fig. 3 zeigt.The 'safety double valve consists of the main valve body part 4 with the short pipe socket 3o, the two front ends of which serve as valve seats and from which the outlet nozzle 7 branches off into the open. A wall 3a separates the two Rooms 16 and 17 from each other, one of which mixes the cold water inlet i i, the other is connected to the pipe 9 leading to the consumer points, such as Fig. 3 shows.
Auf .den Ventilsitzen ruhen die Membranen 18 und 19 mit ihrer metallischen Abstützung 2o und 2 i, die durch die Feder 25 einstellbar belastet sind. Mit ihrem Rand sind sie im Gehäuse eingespannt, und zwar durch die Kappen 33, die mit dem Gehäusehauptteil 4 verschraubt sind. Der Einstellmechanismus für die Belastungsfedern mit dem Widerlager z7 und der plombierbaren 'Steilspindel 24 bietet keine Besonderheiten. The membranes 1 8 and 1 9 rest on the valve seats with their metallic supports 2o and 2 i, which are loaded adjustable by the spring 25. With their edge they are clamped in the housing, namely by the caps 33 which are screwed to the main housing part 4. The adjustment mechanism for the loading springs with the abutment z7 and the sealable 'steep spindle 24 offers no special features.
Entsteht ein schädlicher Überdruck auf der Speisewasserzuführung oder Heißwasserabflußseite, so pflanzt sich dieser Überdruck in das Innere des Gehäuses 4 fort und hebt eine der beiden Membranen oder beide zusammen gegen die Kraft der Federbelastung ab, so daß der Überdruck durch den `Stutzen 3o und den Abzweig 7 ins Freie in das Auffanggerät 3 5 entweichen kann.If there is a harmful overpressure on the feed water supply or Hot water discharge side, this overpressure is planted in the interior of the housing 4 and lifts one of the two membranes or both together against the force of the Spring loading, so that the overpressure through the `` connection 3o '' and branch 7 can escape into the open air into the fall arrester 3 5.
