Description
Dampfkesselspeiseregler mit Ausdehnungsrohr. Die Erfindung betrifft eine Verbesserung des Dampfkesselwasserstandsreglers mit Ausdehnungsrohr nach Patent q.oa28o. Die Verbesserung besteht darin, daß, um an Stelle eines Doppelkolbens im Speiseventil zwei Ventilkegel verwenden zu können, am Verbindungsstück zwischen dem langen Arm des einen Übersetzungshebels und, dem das Speiseventil steuernden Übersetzungshebel anstatt des unteren Bolzenloches ein länglicher Schlitz mit einer Stellschraube angeordnet ist. Man kann dadurch einen beliebigen toten Gang des oberen Übersetzungshebels erzielen. `'Fenn der lange Arm des Übersetzungshebels durch Ausdehnen des Metallrohres gehoben wird, muß sich der Hebel erst eine bestimmte Höhe leer heben, ehe er den das .Speiseventil steuernden Hebel zum Öffnen des Speiseventils mithebt. Aber beim geringsten Zusammenziehen des Ausdehnungsrohres sinken sofort beide Hebel gleichzeitig, wodurch ein schnelles Schließen des Speiseventils eintritt, ein weiteres Sinken des Hebels nimmt der tote Gang auf.Steam boiler feed regulator with expansion pipe. The invention relates to an improvement of the steam boiler water level regulator with expansion pipe according to the patent q.oa28o. The improvement is that in order to replace a double piston in the Feed valve to be able to use two valve cones on the connector between the long arm of one transmission lever and the one that controls the feed valve Transmission lever instead of the lower bolt hole an elongated slot with a Adjusting screw is arranged. You can use it to create any dead corridor of the upper one Achieve translation lever. `` 'Fenn the long arm of the transmission lever by stretching it out of the metal pipe is lifted, the lever must first be empty a certain height before he pulls the lever controlling the feed valve to open the feed valve with. But at the slightest contraction of the expansion pipe they sink immediately both levers at the same time, causing the feed valve to close quickly, a further drop of the lever takes up dead gear.
In der Abbildung ist ein Längsschnitt des Speiseventils mit der Hebelanordnung in vergrößertem Maßstab dargestellt.The figure shows a longitudinal section of the feed valve with the lever assembly shown on an enlarged scale.
Die Wirkungsweise der Vorrichtung ist die bekannte. Füllt sich durch Sinken des Kessel-Wasserstandes das Ausdehnungsrohr mit Dampf, so wird durch die Ausdehnung des Rohres der lange Arm des Übersetzungshebels i gehoben und zugleich Verbindungsstück 1, bis Stellschraube x den unteren Bolzen pl- berührt. Durch weiteres Heben des Hebels i wird nun auch der das Speiseventil o. dgl. steuernde Übersetzungshebel g gehoben und das Speiseventil zum Speisen des Kessels geöffnet, bis durch Steigen des Wasserstandes im Kessel das Ausdehnungsrohr sich wieder mit Wasser füllt und durch seine Abkühlung und Zusammenziehen ein gleichzeitiges Sinken des langen Armes des Übersetzungshebels i und des das Speiseventil o. dgl. steuernden Übersetzungshebelsg eintritt. Dadurch wird das Speiseventil wieder geschlossen.The mode of operation of the device is known. If the expansion pipe fills with steam as the boiler water level drops, the expansion of the pipe lifts the long arm of the transmission lever i and at the same time the connector 1 until the adjusting screw x touches the lower bolt pl-. By further lifting the lever i, the transmission lever g that controls the feed valve or the like is lifted and the feed valve is opened to feed the kettle, until the water level in the kettle rises and the expansion pipe fills with water again and it cools down and contracts simultaneous sinking of the long arm of the transmission lever i and the transmission lever g which controls the feed valve or the like occurs. This closes the feed valve again.
