Description
Die Erfindung betrifft eine auf Rohre, Schläuche oder Kanäle vertikal montierbare Vorrichtung zum Zurückhalten aufsteigender Warmluft und aufsteigender Kanalgase in Rohren, Schläuchen oder Kanälen in Gebäudehüllen-Durchbrüchen oder bei Eintritt belasteter Luft gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device on pipes, hoses or channels vertically mountable device for retaining rising hot air and rising channel gases in pipes, hoses or channels in building envelopes breakthroughs or upon entry of contaminated air according to the preamble of claim 1.
Rohre, Schläuche und Kanäle der Haustechnik sowie Flachdachabläufe sind Funktionsöffnungen und werden in der Regel offen und nicht isoliert vom erwärmten Innenraum nach aussen geführt. Das Innenraumklima erwärmt die Luftsäule im Rohrinnern durch Wärmetransmission und lässt diese durch Konvektion aufsteigen und in die Umgebung entweichen. Der Energieverlust eines Sanitärdunstrohres mit einem Durchmesser von 110 mm während einer Heizperiode beträgt für ein Einfamilienhaus zwischen 50-100 Liter Heizöläquivalente.Pipes, hoses and ducts of building technology as well as flat roof drains are functional openings and are usually led outwards and not isolated from the heated interior to the outside. The indoor climate heats the air column inside the pipe by heat transmission and causes it to rise by convection and escape into the environment. The energy loss of a sanitary pipe with a diameter of 110 mm during a heating period amounts to between 50 and 100 liters of heating oil equivalents for a detached house.
Mit der offenen Fallstrangführung und einem Dunstrohr über Dach werden Unterdruck- oder Überdruckzustände, wie sie in Kanalisationssystemen auftreten, verhindert. Unterdruck würde die Siphonierung behindern (den Sperrwasserstand herausziehen) und Kanalgase könnten mit Überdruck in den Sanitärraum geraten.With the open casing strand guide and a roof vent pipe, negative pressure or overpressure conditions, such as occur in sewage systems, are prevented. Vacuum would hinder the siphoning (pull out the water level) and sewer gases could get into the sanitary room with overpressure.
Auch bei durch die Dachisolation geführten Dachgullys hat man das thermische Leck durch den Warmluftaustrag bis jetzt unterschätzt oder sogar nicht beachtet. Ein solches Rohr kann pro Heizperiode Transmissionsverluste von bis zu 100-140 Liter Heizöläquivalente verursachen.
Dachgullys werden in der Regel offen nur mit einem Laubfanggitter versehen montiert. Das Innenraumklima erwärmt die Luftsäule im Rohrinnern durch Wärmetransmission und lässt diese durch Konvektion aufsteigen und in die Umgebung entweichen. Das Regenfallrohr penetriert die Dachisolation wie ein Kamin und verbindet das Innenraumklima mit der Aussenluft. Besonders mit der zunehmenden Isolationsstärke der Gebäudehülle wird das Energieverlust-Potential grösser. Speziell die weitverbreiteten Unterdruck-Entwässerungssysteme ermöglichen das weitgehend gefällslose Verlegen der Regenfallleitungen im Gebäudeinnern. Die warmseitige Rohrabwicklung wird dadurch vergrössert und damit wird auch der Transmissionsverlust entsprechend grösser. Solche Leitungen werden standardmässig nur mit minimaler Schwitzwasserisolation in einer Dicke von 1-2 cm versehen oder unisoliert einbetoniert.
Vergleichbare Energieverlustquellen sind nach aussen führende Ventilationskanäle für die Raumbe- und -entlüftung im Ruhezustand und mit undichten Schliessvorrichtungen. In Mehrfamilienhäusern werden innenliegende Räume einzeln mit Ventilatoren entlüftet.Even with guided by the roof insulation roof gullies, the thermal leak by the hot air discharge has been underestimated or even ignored. Such a pipe can cause transmission losses of up to 100-140 liters of heating oil equivalents per heating period.
Roof gullies are usually mounted open only with a leaf trap grille. The indoor climate heats the air column inside the pipe by heat transmission and causes it to rise by convection and escape into the environment. The downpipe penetrates the roof insulation like a chimney and connects the indoor climate with the outside air. Especially with the increasing insulation strength of the building envelope, the energy loss potential becomes greater. Especially the widespread vacuum drainage systems allow the largely precipitation-free laying of the rainfall pipes inside the building. The warm pipe development is thereby increased and thus also the transmission loss correspondingly larger. By default, such pipes are only provided with minimal condensation insulation in a thickness of 1-2 cm or embedded in concrete without insulation.
Comparable energy loss sources are outwardly leading ventilation ducts for room ventilation in hibernation and with leaky closing devices. In multi-family houses, interior rooms are individually ventilated with fans.
Seit ca. dreissig Jahren sind Unterdruckventile als Ersatz für offene Sanitärdunstrohre im Einsatz. Diese Ventile werden im Gebäudeinnern auf die Fallstränge aufgesetzt. Bei Unterdruck im Fallstrang öffnet sich eine Klappe und Raumluft wird eingesaugt. Diese Ventile sind Einwegventile, weil sie nur den Unterdruck entspannen und sich sofort wieder verschliessen. Überdruck im Kanalisationssystem kann nicht mehr entweichen. Aus diesem Grunde sind sie nicht überall zugelassen. In gewissen Fällen muss beim Einsatz von Unterdruckventilen die Kanalisation beim Hauptstrang trotzdem offen über Dach entlüftet werden, so dass der Schutz vor Wärmeverlust dort entfällt.For about thirty years, vacuum valves have been used as a replacement for open plumbing pipes. These valves are placed on the falling cords inside the building. At negative pressure in the casing, a flap opens and room air is sucked in. These valves are one-way valves because they only relax the vacuum and close immediately. Overpressure in the sewer system can no longer escape. That's why they are not allowed everywhere. In certain cases, when using vacuum valves, the sewer system in the main line still has to be ventilated open on the roof, so that there is no protection against heat loss.
Geruchsbelästigung durch hochsteigende Kanalisations-Entlüftungen aus Sanitärdunstrohren in der Nähe von Terrassen, Balkonen oder Dachgaubenfenster etc. sind an der Tagesordnung. Die nachträgliche Sanierung ist mit grossem Aufwand verbunden.
Bekannt ist auch der relativ grosse Aufwand der Kanalgasabtrennung bei Regenwasser-Fallrohranschlüssen an die Mischkanalisation. Es müssen zu diesem Zweck im Sockelbereich der Regenfallrohre siphonierte Schächte eingebaut werden. Bei mangelhafter Wartung können diese verstopfen. Mit diesem Schacht werden die Kanalgase zurückgehalten. Die aggressiven Kanalgase wirken neben den üblen Gerüchen korrosiv auf die metallenen Fallrohre. Membranventile eignen sich ebenfalls zum Fernhalten von unerwünschtem Luftzutritt in Gebäude oder Maschinen.Odor nuisance through high-rising sewer ventilation from sanitary drainpipes near terraces, balconies or dormer windows etc. are on the agenda. The subsequent renovation is associated with great effort.
Also known is the relatively large expense of sewer gas separation in rainwater downcomers to the mixing sewer. It must be installed for this purpose in the base area of the rainwater pipes siphonierte shafts. In the case of poor maintenance, these can become clogged. With this shaft, the channel gases are retained. The aggressive channel gases have a corrosive effect on the metal downpipes in addition to the bad odors. Diaphragm valves are also suitable for keeping unwanted air in buildings or machinery away.

Die Erfindung hat sich daher zur Aufgabe gemacht, eine auf Rohre oder Kanäle vertikal montierbare Vorrichtung zu schaffen, welche Geruchsbelästigungen, aggressiven Kanalgase und/oder den unnötigen Warmluftabfluss oder Eintritt von belasteter Luft zu unterbinden.The invention has therefore set itself the task of creating a pipe or channels vertically mountable device which odor nuisance, aggressive duct gases and / or the unnecessary hot air outlet or entry of contaminated air to prevent.
Diese Aufgabe wird mit einer auf Rohre oder Kanäle vertikal montierbaren Vorrichtung gemäss den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a pipe or channels vertically mountable device according to the features of claim 1.
Die Erfindung ermöglicht es, dass die Verschlussklappe durch die Ausformung der Schlitze und der als Gelenke fungierenden Biegelinien und die Materialeigenschaften der Membrane sowohl das Durchfliessen von Wasser und Ansaugen von Luft von aussen zulässt als auch nach Beendigung des Niederschlages oder Spülvorgangs sofort in die Ausgangslage zurückklappt. Bei wenig Wasserfluss öffnet sich die Verschlussklappe wenig, bei grossem Wasseranfall wird die Verschlussklappe durch den Fluidfluss vollständig geöffnet.
In geschlossenem Zustand bewirkt die Verschlussklappe einen Warmluftanstau. Die Warmluft bildet unter der Verschlussklappe einen Warmluftpfropfen, der den ständigen Energieabfluss durch die aufsteigende Warmluft an die Umgebung effizient unterbindet. Der Energieverlust reduziert sich auf die Oberfläche zwischen der Kaltseite der Verschlussklappe und Membrane und dem warmseitigen Warmluftpfropfen an der Verschlussklappe entstehende Auskühlung. Der Rohrquerschnittsverlust ist dann vernachlässigbar. Der Warmluftstau erwärmt die Membran und verhindert das Einfrieren der Verschlussklappe im Winter. Eine hydrophobe Ausrüstung, eine Schutzkappe und die vertikale Lage unterstützen die Wintertauglichkeit.The invention makes it possible that the closure flap by the formation of the slots and acting as joints bending lines and the material properties of the membrane allows both the flow of water and suction of air from the outside and immediately after the precipitation or rinsing process folds back into the starting position. If the flow of water is low, the flap does not open very much. In the event of a large amount of water, the flap is completely opened by the fluid flow.
When closed, the flap causes a hot air accumulation. The hot air forms under the flap a hot air plug, which efficiently prevents the constant flow of energy through the rising warm air to the environment. The energy loss is reduced to the surface between the cold side of the flap and membrane and the warm side warm air plug on the flap resulting cooling. The pipe cross-section loss is then negligible. The warm air accumulation heats the membrane and prevents the shutter from freezing in winter. A hydrophobic finish, a protective cap and the vertical layer support the winter suitability.
Wird die Verschlussklappe in Sanitärdunstrohre eingebaut, kann Überdruck nach aussen entweichen, weil bei Druckanstieg die Verschlussklappe nur soweit nach aussen gedrückt wird, dass der Druck entweichen kann. Nach dem Druckausgleich, der nach wenigen Sekunden hergestellt ist, schliesst sich die Verschlussklappe wieder. Wenn im Sanitärfallrohr durch abfliessendes Wasser Unterdruck entsteht, öffnet sich die Verschlussklappe, indem die Klappensegmente sich nach innen verformen und den Querschnitt schlitzförmig öffnen und Luft angesaugt wird. Die Verschlussklappe kann mit herkömmlichen Unterdruckventilen kombiniert eingesetzt werden.
Bei einer vertikalen Anordnung der türchenförmigen Klappen kann eine Erwärmung des Materials keinen Einfluss auf die Dichtigkeit der Verschlusskappe nehmen und bei Frost ist eine Vereisung und damit ein Verschluss der Verschlussklappe dadurch ausgeschlossen, dass Kondenswasser stets entlang der Kanten der Verschlussklappe nach unten rinnt und sich in der tieferliegenden spitzwinkligen Ecke sammelt, wo der Einfluss der Vereisung vernachlässigbar ist. Durch die Druckunterschiede verändert sich die Membran-Oberflächenspannung. Die Kontaktzone der Klappen zur Membran ist gering, sie beschränkt sich auf die Membrandicke. Dies unterstützt die Wintertauglichkeit zusätzlich. Durch Einlegen oder Aufkleben feiner federelastischer Drähte, Metall- oder Kunststoffstäbe oder Eingiessen von Mikro- oder Nanomaterialien in die Membran kann die Festigkeit der Verschlussklappe erhöht werden, ohne deren Elastizität zum Öffnen wesentlich zu beeinträchtigen.
Die wirksame Ventilfläche kann durch die vertikale Membrananordnung und einer freien Wahl der Verschlussklappen-Höhe unabhängig vom Kanal- oder Rohrquerschnitt bestimmt werden. Die wirksamen Ventilflächen können daher viel grösser als der Rohrquerschnitt sein. Es lassen sich folglich auch in sehr klein bemessenen Rohren und Kanälen geeignet gross dimensionierte Verschlussklappen anordnen. Gleichzeitig können Schallübertragungen in schallführenden, nebeneinander liegenden Luftsäulen, z.B. in Mehrfamilienhäusern, durch diese Verschlussklappen unterbrochen und dadurch der Luftschall oder Geräusche auch von die Rohre auf dem Dach einhüllenden Blechabdeckungen verhindert werden.If the flap is installed in plumbing, excess pressure can escape to the outside, because when the pressure rises, the flap is only pushed out to the extent that the pressure can escape. After the pressure equalization, which is made after a few seconds, closes the shutter again. If negative pressure develops in the sanitary downfall pipe due to running water, the closing flap opens as the flap segments deform inwards and open the cross-section like a slit and air is sucked in. The flap can be used in combination with conventional vacuum valves.
In the case of a vertical arrangement of the door-shaped flaps, heating of the material can have no effect on the tightness of the closure cap and icing and thus closure of the closure flap is precluded in the event of frost in that condensation always runs down along the edges of the closure flap and lodges in the flap deeper acute-angled corner collects where the influence of icing is negligible. Due to the pressure differences, the membrane surface tension changes. The contact zone of the flaps to the membrane is low, it is limited to the membrane thickness. This additionally supports the winter suitability. By inserting or sticking fine spring-elastic wires, metal or plastic rods or pouring of micro- or nanomaterials into the membrane, the strength of the flap can be increased without affecting their elasticity to open significantly.
The effective valve area can be determined by the vertical membrane arrangement and a free choice of the flap height regardless of the channel or tube cross-section. The effective valve areas can therefore be much larger than the pipe cross-section. Consequently, it is possible to arrange appropriately sized shutters even in very small pipes and ducts. At the same time sound transmissions in sound-carrying, adjacent air columns, eg in apartment buildings, interrupted by these flaps and thus the airborne noise or noise from the pipes on the roof enveloping sheet metal covers can be prevented.
Die Verschlussklappen können aus einem elastischen Band endlos hergestellt werden und die entsprechende Anzahl von Verschlussklappen beim Konfektionieren vom Band abgeschnitten oder als direkt auf die Tragstruktur aufgespritzte Membran aufgebracht werden. Dadurch lässt sich eine äusserst kostengünstige Herstellung erreichen.The closure flaps can be produced endlessly from an elastic band and the corresponding number of flaps can be cut from the band during assembly or applied as a membrane sprayed directly onto the support structure. As a result, an extremely cost-effective production can be achieved.
In Kombination mit geeigneten Stützprofilen und mehreren Klappen in Serie können grossflächige Ventilmembranen hergestellt werden und in der Lüftungstechnik eingesetzt werden. Die Klappen benötigen keine aktive Steuerung oder Antriebseinheit. Der Betrieb ist deshalb einfach, wartungsfrei und kostengünstig.In combination with suitable support profiles and several flaps in series, large-area valve diaphragms can be produced and used in ventilation technology. The flaps do not require an active control or drive unit. The operation is therefore simple, maintenance-free and cost-effective.
