Description

KAISERLICHESIMPERIAL

PATENTAMPATENTAM

Auf der Zeichnung sind ein Längsschnitt eines Theiles des Wasserstandszeigers und ein Querschnitt nach A-B von demselben dargestellt. The drawing shows a longitudinal section of part of the water level pointer and a cross section to AB of the same.

Die Spindel S des Wasserstandsventiles C hat an der Abschlufsfläche desselben eine Verlängerung, welche mit ihrer breiten Seite in den Kanal pafst und für die Aufnahme einer Spiralfeder D und des von derselben offen gehaltenen Rückschlagventiles V am Ende rund gedreht ist. Zerbricht das Wasserstandsglas, so schliefst der ausströmende Dampf (oder eine andere Flüssigkeit) das Rückschlagventil V unmittelbar. Die Spiralfeder D mufs schwach genug sein, um bei einem geringen inneren Ueberdruck sofort nachzugeben.The spindle S of the water level valve C has an extension on the closing surface of the same, which fits with its broad side into the channel and is turned round at the end to accommodate a spiral spring D and the check valve V held open by the same. If the water level glass breaks, the escaping steam (or another liquid) closes the non-return valve V immediately. The spiral spring D must be weak enough to give way immediately in the event of a slight internal excess pressure.

Wird der Kesselbetrieb eingestellt, so schliefst man durch Drehen der Spindel S das Wasserstandsglas durch das Ventil C ab, wobei das Ventil V mit der Verlängerung in den Kessel hineingeht; dadurch, dafs letztere sich hierbei dreht, befreit sie den Kanal von Schlamm u. dergl. und verhütet dessen Verstopfen.If the boiler operation is stopped, the water level glass is closed by turning the spindle S through the valve C , the valve V with the extension going into the boiler; in that the latter rotates in the process, it frees the channel of sludge and the like and prevents it from clogging.

Diese Vorrichtung kann aufser an Dampfkesseln auch an Reservoirs angebracht werden, in welchen kostbare oder gefährliche Flüssigkeiten enthalten sind.This device can be attached to reservoirs in addition to steam boilers, which contain precious or dangerous liquids.

Claims (1)

Patent-Anspruch:Patent claim: An Wasserstandszeigern, bei welchen am Ende einer rechteckigen Verlängerung einer Schraub-ventilspindel ein in den Kessel hineinragendes Rückschlagventil angebracht ist, die Verbindung von Spindel und Ventil durch einen in einem Schlitz des Ventiles geführten Querstift unter Einschaltung einer Schraubenfeder zwischen Spindel und Ventil.At water level pointers, where at the end of a rectangular extension a Screw valve spindle a non-return valve protruding into the boiler is attached, which Connection of spindle and valve through a cross pin guided in a slot in the valve with the insertion of a helical spring between the spindle and the valve.
