Description

Vorrichtung an Dampfkesseln, um die Schaulänge des Wasserstandes bis auf den Abstand der Kesselstutzen oder darüber hinaus zu vergrößern Es sind Wasserstandskörper bekannt, mit deren Hüfe unter Benutzung der vorhandenen Wasserstandsstutzen es möglich ist, Wasserstandsschwankungen. in Dampfkesseln Über eine nahezu der Entfernung der Stutzen eritsprechende Länge sichtbar zu machen. Sobald der Wasserspiegel in den Bexeicli des oberen Rohrstutzens tritt, wird der Querschnitt für den DampfdurcIrfluß vom Kessel zu dem Kopf des Wasserstandskörpers vexringert. Infolgedessen können die durch die Abkühlung dauernd im WasserstandskörpeT auftretenden Niederschlagsverluste nicht ersetzt werden, so daß im Wassexstandskörper ringerer Druck herrscht als im Kessel, wodurch der Wasserstand höher, angezeigt wird, als er tatsächlich im Kessel vorhanden ist.Device on steam boilers to keep the visible length of the water level up to increase the distance between the boiler nozzles or beyond. They are water level bodies known, with their hip using the existing water level connection it is possible is, water level fluctuations. in steam boilers about a distance of almost the same To make the length visible. As soon as the water level is in the When the upper pipe socket occurs, the cross section for the steam flow becomes from the boiler to the head of the water level body. As a result, you can the precipitation losses that occur continuously in the water level body as a result of the cooling not be replaced, so that there is less pressure in the Wassexstandskörper than in the Boiler, which means that the water level is displayed higher than it actually is in the boiler is available.

Diese Feblanzeigen werden gemäß der Erfindung dadurch vermieden, daß der Kopf des Wässerstandskörpers duich eine Druckaus-gleichleitung oberhalb der I###s.elstu--tzen mit dem Kesseldampfraum verbunden ist, durch welche die Gleichheit des Druckes im Kessel und im Wasserstandskörper bis zum obersten sichtbaren Wasserstand gewährleistet wird.These February displays are avoided according to the invention in that the head of the water level body duich a pressure equalization line above the I ### pillar is connected to the boiler steam room, through which the equality the pressure in the boiler and in the water level body up to the highest visible water level is guaranteed.

Um eine richtige Wasserstandsan2eige auch in dem Sicherheitsbereich unterhalb des unteren Verbindungsstutzens zwischen Wasserstandskörpern und Dampfkessel. zu gewährleisten, soll gemäß der Erfindung auch das untere Ende des Wasserstandskörpers mittels einer Verbindungsleitung unterhalb der Kessel-stutzen mit dem Wasserraum des Kessels in Verbindung stehen. Hierbei wird man je- doch vorsichtshalber den niedrigst zulässigen Widerstand nicht unterhalb des unteren Verbindungsstutzens vorsehen. Für den Fall, daß der zulässig niedrigste Wasserstand doch einmal unterschritten ist, ermöglicht die Wasserverbindungsleitung den richtigen überblick über den jeweiligen Wasserstand, was im Gefahrsfalle von großer Wichtigkeit ist.To get a correct water level indication in the safety area below the lower connection piece between the water level body and the steam boiler. To ensure, according to the invention, the lower end of the water level body should also be in connection with the water space of the boiler by means of a connecting line below the boiler nozzle. As a precaution, however, the lowest permissible resistance is not provided below the lower connecting piece. In the event that the water level falls below the permissible lowest level, the water connection line enables the correct overview of the respective water level, which is of great importance in the event of danger.

In der Zeichnung ist eine Anordnung geinäß der Erfindung dargestellt, und zwar zeigt Abb. i eine Vorderansicht, Abb.2 eine Draufsicht eines mit dem Erfindungsgegenstand ausgerüsteten Dampfkessels.In the drawing, an arrangement according to the invention is shown, namely Fig. i shows a front view, Fig.2 shows a plan view of one with the subject matter of the invention equipped steam boiler.

Am Kessel a befinden sich die Wasserstandsstutzenb und c, durch die der Wasserstandskörpend an den Dampfraum und Wasserraum des Kesselsa angeschlossen ist. An dem Wasserstandskörperd ist das Schauglase durch Stutzen / und g angeschlossen, die vorteilhaft im rechten Winkel zu den Stutzen b und c stehen. Am Kopf h des Wasserstandskörpers d ist die Druckausgleichleitung i mit dem Absperrventil k angeschlossen, die im Stutzen 1 in den Diampfraum des Kessels a mündet. Am unteren Ende des Wasserstandskörpers,d ist die Wasserverbindungsleitung n mit dem Absperrventilo angeschlossen, die am tiefgelegenen Stutzenp in den Wasserraum des Kesselsa mündet. Die Stutzenb und c können nach öffnung der Sichraubenq und r, die Stutzen f und g nach öffnung der Schräuben s und 1 geradlinig durchgestoßen werden.On boiler a there are water level nozzles b and c, through which the water level body is connected to the steam space and water space of the boiler a. The sight glass is connected to the water level body by connecting pieces / and g , which are advantageously at right angles to connecting pieces b and c. The pressure equalization line i with the shut-off valve k is connected to the head h of the water level body d and opens into the steam chamber of the boiler a in the nozzle 1. At the lower end of the water level body, d, the water connection line n is connected to the shut-off valve, which opens into the water space of the boilera at the low-lying nozzle p. The nozzles b and c can be pushed through in a straight line after opening the locking screws q and r, the nozzles f and g after opening the screws s and 1.
