Abstract

The pressure equalising membrane (2) is built directly into a hot water boiler (1). Changes in vol. during heating are levelled out. The membrane is connected to a blind flange (2), which it itself screwed to the flange (4) of the boiler. The membrane is protected by four rods (5). During the annular cleaning of the boiler, the membrane should be checked and changed if necessary. Since the membrane valve is outside the boiler, the nitrogen pressure in the membrane can be checked at any time. In a hot water heating system, the membrane can be in a separate container if there is no room for it to be built in.

Description

Beim Aufheizen eines Warmwasserboilers, indirekt oder direkt beheizt, dehnt sich das Wasservolumen im Boiler aus, wodurch die Boilerwandung mit einem höheren Druck belastet wird. Deshalb ist ein Sicherheitsventil einge­ baut, das den Überdruck abläßt, mit dem Nachteil, daß bei jedem Aufheizen Wasser verloren geht.When heating a hot water boiler, indirectly or directly heated, the water volume in the boiler expands out, causing the boiler wall to have a higher pressure is charged. Therefore a safety valve is switched on builds that relieves the excess pressure, with the disadvantage that water is lost each time it is heated.

Zweckmäßigerweise wird ein Ausdehnungsgefäß vor den Boiler montiert, in dem der Überdruck sich ausdehnen kann. Dies ist aber vom DVGW nicht zugelassen, da es in dem Ausdehnungsgefäß durch abgestandenes Wasser zur Legio­ nellenbildung kommen kann.An expansion vessel is expediently placed in front of the Boiler installed in which the overpressure can expand. However, this is not permitted by the DVGW because it is in the Expansion tank through stale water to the Legio nellenbildung can come.

Auch entstehen höhere Montagekosten durch die Montage des Ausdehnungsgefäßes.The assembly costs also increase of the expansion tank.

Die Erfindung liegt darin, eine Druckausgleichsmembrane zu konstruieren die umflossen wird, damit sich keine Le­ gionellen durch abgestandenes Wasser bilden können und die Montagekosten für das Ausdehnungsgefäß eingespart werden können.The invention is a pressure compensation membrane to construct the flow around, so that no Le can form gionella by stale water and the installation costs for the expansion tank saved can be.

Gemäß der Erfindung wird dies dadurch erreicht, daß eine Druckausgleichsmembrane direkt in den Boiler eingebaut ist, oder nachträglich eingebaut werden kann, um die Volumenän­ derung beim Erwärmen des Mediums aufzunehmen.According to the invention, this is achieved in that a Pressure compensation membrane is built directly into the boiler, or can be retrofitted to increase the volume change when heating the medium.

Um dies zu erreichen, ist eine Druckausgleichsmembrane mit der Ventilseite an einem Blindflansch befestigt. Zweckmäßigerweise ist oder wird der Blindflansch mit der Druckausgleichsmembrane in die Reinigungsöffnung, bzw. Handloch des Boilers eingeschoben und mit dem Blindflansch am Flansch des Boilers verschraubt. Um eine bessere Führung beim Ein- und Ausbau (z. B. beim Reinigen des Boilers) zu erreichen und die Membrane vor Verletzungen oder Abknicken zu schützen, sind rundum vier oder mehr Stäbe am Flansch befestigt, in der die Membrane gelagert ist. Beim jährlichen Reinigen des Boilers, wie es die DIN vorschreibt, kann auch die Druckausgleichsmembrane überprüft werden und evtl. leicht ausgetauscht werden. Da das Ventil der Membrane außerhalb des Boilers liegt, kann zu jeder Zeit der Druck des Stickstoffes in der Druckausgleichsmembrane überprüft werden. Desgleichen kann die Druckausgleichs­ membrane in einen Heizkessel der Warmwasser-Heizungsanlage, wenn die Größe es erlaubt, eingebaut werden oder in einen separaten Behälter.To achieve this, there is a pressure equalization membrane attached to a blind flange with the valve side. The blind flange is or is expediently included the pressure compensation membrane in the cleaning opening, or hand hole of the boiler inserted and with the Blind flange screwed to the flange of the boiler. Around better guidance during installation and removal (e.g. when Clean the boiler) and reach the membrane Protecting injuries or kinking is all around  four or more rods are attached to the flange in which the Membrane is stored. When cleaning the Boilers, as prescribed by DIN, can also do that Pressure equalization membrane are checked and possibly can be easily replaced. Because the valve of the membrane outside of the boiler, at any time Pressure of nitrogen in the pressure equalization membrane be checked. Likewise, the pressure compensation membrane in a boiler of the hot water heating system, if the size allows it to be built in or in one separate container.

Die Zeichnung gibt zwei Beispiele wiederThe drawing shows two examples

Fig. 1 zeigt einen Warmwasserboiler 1, der einfachheitshalber ohne Wärmetauscher aus der Seitenansicht im Schnitt gezeichnet ist. Unmittelbar über dem Boilerboden ist die Druckausgleichsmembrane 2 in den Boiler 1 eingeschoben. Der Blindflansch 3 der Druckaus­ gleichsmembrane 2 ist mit dem Flansch 4 des Boilers 1 verschraubt. An dem Flansch 3 der Druckausgleichs­ membrane 2 sind vier Stäbe 5 angebracht, in der die Membrane 2 gelagert ist und gleichzeitig ge­ schützt wird für den Ein- und Ausbau beim Rei­ nigen des Boiler 1. Das Ventil 6 der Membrane 2 ist außerhalb des Boiler 1. Fig. 1 shows a hot water boiler 1 , which is drawn for simplicity without a heat exchanger from the side view in section. Immediately above the boiler bottom, the pressure compensation membrane 2 is inserted into the boiler. 1 The blind flange 3 of the pressure compensation diaphragm 2 is screwed to the flange 4 of the boiler 1 . Membrane to the flange 3 of the pressure equalization 2, four rods 5 attached, in which the diaphragm 2 is mounted and at the same time protects ge is for the installation and removal during Rei Nigen of the boiler. 1 The valve 6 of the membrane 2 is outside the boiler 1 .

Fig. 2 zeigt eine ausgebaute Druckausgleichsmembrane 2 mit dem Flansch 3 und den vier daran angebrachten Führungen bzw. Schutzstäben 5, in der die Membrane 2 gelagert ist. Fig. 2 shows a developed pressure compensation diaphragm 2 with the flange 3 and the four attached guides or protective rods 5, in which the diaphragm 2 is mounted.
