Description
Druckbehälter, insbesondere für einen WarmwasserbereiterPressure vessels, in particular for a water heater
Die Erfindung betrifft einen Druckbehälter, insbesondere für einen Warmwasserbereiter, mit einem wasserundurchlässigen Kunststoff-Innenbehälter und einer diesen armierenden Glasfaserbewicklung.The invention relates to a pressure vessel, in particular for one Water heater, with a waterproof plastic inner container and one of these reinforcing fiberglass wrapping.
Bei derartigen Druckbehältern ist der Innenbehälter (Liner) im Blasverfahren hergestellt und als solcher nicht geeignet, größere Wasserdrücke aufzunehmen. Es wurde deshalb vorgeschlagen, den Innenbehälter mit auf ganzer Länge kunststoffgetränkten Glasfäden (Rovings) zu bewickeln. Hierdurch tritt allerdings eine unerwünschte Geruchsbildung im Brauchwasser auf, die durch Diffusion des die Glasfäden tränkenden Kunststoffes, z. B. styrolhaltiges Harz, vorzugsweise vor und während dessen Aushärtung in dem Innenbehälter entsteht. Darüber hinaus ist die vollständige Tränkung der Glasfaserbewicklung mit Kunststoffmasse teuer.In such pressure vessels, the inner vessel (liner) is blown manufactured and as such not suitable to absorb larger water pressures. It it was therefore suggested that the inner container be soaked in plastic over its entire length To wind glass threads (rovings). However, this creates an undesirable odor in the service water, which by diffusion of the plastic soaking the glass threads, z. B. styrene-containing resin, preferably before and during its curing in the Inner container is created. In addition, the glass fiber wrapping is completely impregnated with plastic compound expensive.
Aufgabe der Erfindung ist es, einen Druckbehälter eingangs genannter Art vorzuschlagen, bei dem eine Geruchsannahme des Brauchwassers vermieden ist und dessen Herstellungskosten verringert sind.The object of the invention is to provide a pressure vessel mentioned at the beginning To propose a type in which an odor acceptance of the domestic water is avoided and whose manufacturing costs are reduced.
Nach der Erfindung wird obige Aufgabe dadurch gelöst, daß die Glasfaserbewicklung an Einzel stellen des Innenbehälters mittels stellenweise aufgebrachter Kunststoffmasse fixiert und/oder mittels einer um die Glasfaserbewicklung geschäumten, als Wärmedämmung dienende Kunststoffschicht an dem Innenbehälter gehalten ist. Durch die nur stellenweise Kunststofftränkung der Glasfasern wird der Verbrauch von Kunststoffmasse, z. B. Lösungsmittel (styrol)- haltigen Harzes wesentlich reduziert. Gleichzeitig ist die Geruchsbildung im Brauchwasser durch die Reduzierung der eingesetzten Kunststoff-Tränkmenge vermieden.According to the invention, the above object is achieved in that the glass fiber winding at individual points of the inner container by means of plastic compound applied in places fixed and / or by means of a foamed around the glass fiber wrapping, as thermal insulation Serving plastic layer is held on the inner container. Through that only in places Plastic impregnation of the glass fibers will reduce the consumption of Plastic compound, z. B. Solvent (styrene) - containing resin is significantly reduced. Simultaneously is the formation of odors in the process water due to the reduction in the amount of plastic soaked in the water avoided.
Die um die Glasfaserbewicklung geschäumte wärmedämmende Kunststoffschicht, die insbesondere ein Polyurethan-Mantel ist, wird ein Schutz und ein sicherer Halt der Glasfaserbewicklung an dem Innenbehälter erreicht. In bestimmten Anwendungsfällen genügt auch die um die Glasfaserbewicklung geschäumte Kunststoffschicht allein zur Fixierung der Glasfaserbewicklung.The heat-insulating plastic layer foamed around the glass fiber wrapping, which is in particular a polyurethane sheath, becomes a protection and a secure hold the fiberglass wrapping on the inner container. In certain use cases The plastic layer foamed around the glass fiber wrapping is also sufficient on its own Fixation of the fiberglass wrapping.
Da die Kunststoffmasse, z. B. styrolhaltiges Harz, weitgehend oder ganz entfällt, verringert sich auch die Aushärteenergiemenge und -zeit derselben. Die Festigkeit des Behälters wird dadurch nicht geschwächt, da diese nur durch die Glasfaserbewicklung bestimmt wird. Um einer Verrottung der Glasfasern infolge Wasserdampfdiffusion vorzubeugen, kann der Innenbehälter mit einem wasserdampfdichten Anstrich oder einer wasserdampfdichten Folie versehen sein.Since the plastic mass, e.g. B. styrene-containing resin, largely or completely omitted, the amount and time of curing energy is also reduced. The strength of the container is not weakened as this is only due to the Fiberglass wrapping is determined. About rotting of the glass fibers as a result of water vapor diffusion To prevent this, the inner container can be coated with a water-vapor-proof coating or a be provided with a water-vapor-proof film.
Weitere Ausgestaltungen der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels: Die Figur zeigt einen erfindungsgemäßen Druckbehälter teilweise geschnitten.Further refinements of the invention emerge from the following Description of an exemplary embodiment: The figure shows one according to the invention Pressure vessel partially cut.
Ein Kunststoff-Innenbehälter 1 trägt an seinen sphärisch gewölbten Enden Versteifungskappen 2 und 3. Diese sind von Aluminium-Formteilen gebildet. Sie weisen Ansätze 4 und 5 auf, mittels denen der Innenbehälter in eine Wickelmaschine einspannbar ist. Durch den Ansatz 5 sind die Anschlußelemente, wie Wasserzulauf, Wasserablauf und Heizkörper, geführt.A plastic inner container 1 carries on its spherically curved Ends of stiffening caps 2 and 3. These are made of molded aluminum parts. They have approaches 4 and 5, by means of which the inner container in a winding machine can be clamped. Through the approach 5, the connection elements, such as water inlet, Water drainage and radiator, guided.
Der Innenbehälter 1 mit den Versteifungskappen 2 und 3 ist mit Glasfasern 6 bewickelt. Die Glasfaserbewicklung 6 überlappt die Versteifungskappen 2 und 3. Die Glasfasern sind nur an wenigen Stellen mit Kunststoffmasse getränkt, beispielsweise in den Bereichen 7 und 8 der Versteifungskappen und in einer Zone 9. Dabei liegen in der Zone 9 die Glasfaserenden einer Bewicklung des zwischen den Versteifungskappen 2 und 3 liegenden Teils des Innenbehälters. In den Bereichen 7 und 8 liegen die Enden einer zusätzlichen1 mit der erstgenannten Bewicklung verzopften Kreuzbewicklung des Innenbehalters und der Versteifungskappen Der bewickelte Innenbehälter 1 ist in einen Schutzmantel eingesetzt. Der Freiraum zwischen Schutzmantel 10 und Innenbehälter 1 bzw Glasfaserbewicklung 6 ist mit einem wärmedämmenden Hartschaumstoff 11, beispielsweise Polyurethan, ausgeschäumt. Die Glasfaserbewicklung ist hierdurch an dem Innenbehälter gehalten und gegen äußere Einflüsse geschützt.The inner container 1 with the stiffening caps 2 and 3 is made with glass fibers 6 wrapped. The fiberglass wrapping 6 overlaps the stiffening caps 2 and 3. The glass fibers are only soaked in a few places with plastic compound, for example in areas 7 and 8 of the stiffening caps and in a zone 9 in zone 9, the fiberglass ends of a winding between the stiffening caps 2 and 3 lying part of the inner container. In the Areas 7 and 8 the ends of an additional1 are twisted with the first-mentioned winding Cross-wrapping of the inner container and the stiffening caps The wrapped inner container 1 is inserted into a protective jacket. The space between the protective jacket 10 and Inner container 1 or glass fiber wrapping 6 is made of a thermally insulating rigid foam 11, for example polyurethane, foamed. The fiberglass wrapping is hereby held on the inner container and protected against external influences.
Im Rahmen der Erfindung ist es möglich1 die Einzelstellen, an denen die Glasfaserbewicklung mit Kunststoffmasse getränkt ist, in je nach der Bewicklungsart geeignete Bereiche zu legen. Liegen die kunststoffgetränkten Bereiche auf den Aluminium-Versteifungskappen, dann ist von vornherein ein Eindiffundieren der Kunststoffmasse in den Innenbehälter vermieden.In the context of the invention, it is possible1 the individual points at which the fiberglass wrapping is impregnated with plastic compound, depending on the type of wrapping to lay suitable areas. If the plastic-soaked areas are on the aluminum stiffening caps, then from the start there is a diffusion of the plastic compound into the inner container avoided.
