Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Einrichten eines Übergangs zwischen einer metallischen Armatur und einem Kunststoffrohr der im Oberbegriff des Anspruches 1 genannten Art. Derartige Vorrichtungen finden insbesondere Verwendung bei Versorgungsleitungen für Gas, Wasser und Abwasser. Hier muss ein solcher Übergang geschaffen werden, beispielsweise von einem Absperrschieber, einem Ventil, einem Metallrohr oder dergleichen zur Versorgungsleitung hin.The The invention relates to a device for establishing a transition between a metallic fitting and a plastic tube of the The preamble of claim 1 mentioned type. Such devices find particular use in supply lines for gas, water and sewage. Here, such a transition must be created, for example, from a gate valve, a valve, a metal tube or the like to the supply line.
Derartige Übergänge werden bisher häufig dadurch geschaffen, dass der Metallstutzen auf seiner Außenseite über Verzahnungen oder ähnliches verfügt auf die ein kurzer Kunststoffstutzen aufgepresst wird. Diese Verbindungsstelle wird dann mit einem Schrumpfschlauch gesichert. An den Kunststoffstutzen wird dann mittels einer Schweißmuffe oder eines Stumpfschweißverfahrens das eigentliche Kunststoffrohr angebracht. Diese Methode weist jedoch einige Nachteile auf. Da Kunststoffrohre in verschiedenen Farben, wie beispielsweise blau, gelb oder schwarz für die verschiedenen Medien und mit unterschiedlichen Wandstärken bei gleicher Nennweite verwendet werden, müssen die verschiedensten Armaturen auf Vorrat gehalten werden, da der Kunststoffstutzen die gleichen Eigenschaften wie das Kunststoffrohr mit dem er verbunden werden soll aufweisen muss. Wird der Anschluss zum Kunststoffrohr mittels einer Schweißmuffe hergestellt, und ist die so entstandene Schweißnaht undicht, muss der Bereich des Kunststoffstutzens an dem sich die Muffe befindet entfernt werden. Dann wird eine neue Schweißmuffe aufgesetzt und der Schweißvorgang erneut durchgeführt. Dies kann jedoch nicht beliebig oft, sondern häufig nur zweimal wiederholt werden, da der Kunststoffstutzen nicht zu lang ausgeführt werden darf um die Handhabung beispielsweise in einem Baustellengraben nicht unnötig zu erschweren. Ist die Schweißnaht dann wieder undicht, so muss die gesamte Armatur ausgetauscht werden.Such transitions are so often by now created that the metal stub has on its outside about serrations or similar on the a short plastic stub is pressed on. This connection point is then secured with a shrink tube. On the plastic socket is then by means of a welding sleeve or a butt welding process the actual plastic pipe attached. However, this method points some disadvantages. Since plastic pipes in different colors, such as blue, yellow or black for the different media and with different wall thicknesses must be used with the same nominal diameter, the most diverse fittings kept in stock, since the plastic nozzle the same Properties like the plastic pipe to which it is connected should have to have. If the connection to the plastic pipe by means a welding sleeve made, and is the resulting weld leaking, the area of the Plastic socket on which the sleeve is located. Then a new welding sleeve put on and the welding process carried out again. However, this can not be repeated any number of times, but often only twice because the plastic sockets are not too long allowed to handle, for example, in a construction site ditch not unnecessary to complicate. Is the weld then leaking again, so the entire valve must be replaced.
Bei einer anderen Vorrichtung verfügt der Metallstutzen auf seiner Innenseite über ein Gewinde, in welches ein Kunststoffstutzen geschraubt und dann gesichert wird. Hier ergeben sich jedoch die gleichen Nachteile bezüglich Vorratshaltung und Anzahl der Verschweißungsversuche wie bei der zuvor erwähnten Vorrichtung.at another device has the metal pipe on its inside over a thread, in which a plastic socket is screwed and then secured. Here arise However, the same disadvantages in terms of stock and number the welding tests as in the aforementioned Contraption.
Aufgabe der Erfindung ist es daher, eine Vorrichtung der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, die unabhängig von der Farbe des Kunststoffrohres verwendet werden kann und bei der alle mit dem Kunststoffrohr direkt in Verbindung bringbare Elemente durch einfache Möglichkeiten ausgetauscht werden können. Dies wird erfindungsgemäß durch die im Anspruch 1 genannten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.task The invention is therefore a device that in the preamble of Claim 1 mentioned to develop, regardless of the color of the plastic pipe can be used and at the all elements directly connectable to the plastic pipe through simple possibilities can be exchanged. This is inventively the measures mentioned in claim 1 achieved the following special significance.
Die Kunststoffmuffe ist so im Inneren des Metallstutzens anbringbar, dass sie mit ihrem Außenende herausragt. Gleichzeitig verfügt sie im Umfangs- und/oder Stirnbereich über wenigstens ein Dichtungsmittel. Weiterhin verfügt die Vorrichtung über eine dreiteilige Halteeinrichtung, welche einen Anschlag am Metallstutzen, eine Schulter an der Kunststoffmuffe und einen Klemmring umfasst. Der Klemmring weist hierbei einen Gegenanschlag für den Anschlag und eine Gegenschulter für die Schulter auf, welche jeweils miteinander in Eingriff bringbar sind. Hierdurch entsteht ein Einbauzustand. Die Kunststoffmuffe kann nun im Einbauzustand mit dem Kunststoffrohr verschweißt werden, wobei zwischen diesem Kunststoffrohr und der metallischen Armatur eine dichte und lösbare Verbindung entsteht. Die Abdichtung der Kunststoffmuffe zum Metallstutzen hin entsteht durch das Dichtmittel in Verbindung mit der dreiteiligen Halteeinrichtung. Diese Einrichtung bewirkt, dass das Dichtmittel an dem Metallstutzen verpresst wird, und so die Abdichtung entsteht. Da die Kunststoffmuffe größtenteils im Inneren des Metallstutzens angeordnet ist, ist die gesamte Vorrichtung von der Farbe des verwendeten Kunststoffrohres unabhängig. Es kann somit für jede beliebige Farbe des Kunststoffrohres die gleiche Vorrichtung verwendet werden, was eine enorme Reduktion des Platzbedarfs für die Vorratshaltung bedeutet. Auch wird der Materialaufwand für den bisher benötigten Kunststoffstutzen eingespart.The Plastic sleeve is so attachable inside the metal stub, that she is with her outside end protrudes. At the same time they in the circumferential and / or forehead area via at least one sealant. Further features the device over a three-part holding device, which a stop on the metal nozzle, a shoulder on the plastic sleeve and a clamping ring comprises. The clamping ring here has a counter-stop for the stop and a counter-shoulder for the shoulder on, which are each engageable with each other. This creates a state of installation. The plastic sleeve can now be welded in the installed state with the plastic pipe, between this plastic pipe and the metallic fitting a dense and detachable Connection arises. The sealing of the plastic sleeve to the metal nozzle towards the sealant in conjunction with the three-part Holding device. This device causes the sealant is squeezed on the metal pipe, and so the seal is created. Since the plastic sleeve mostly is arranged inside the metal nozzle, the entire device of the color of the plastic pipe used independently. It can thus be for any Color of the plastic tube the same device can be used which means a huge reduction in the space required for stockpiling. Also, the cost of materials for the previously required Saved plastic nozzle.
Außerdem können alle mit dem Kunststoffrohr unmittelbar in Verbindung stehenden Elemente einfach ausgetauscht werden. Hierzu muss nur die Halteeinrichtung gelöst werden und die Kunststoffmuffe ist aus dem Metallstutzen entnehmbar. Dies ist beispielsweise dann vorteilhaft, wenn die Schweißnaht zwischen der Kunststoffmuffe und dem Kunststoffrohr fehlerhaft ist, beispielsweise weil das Kunststoffrohr nicht sorgfältig genug für den Verschweißungsvorgang vorbereitet wurde. Auch wenn mehrere Verschweißungen fehlerhaft verlaufen sollten, so können immer wieder die entsprechenden Kunststoffmuffen ausgetauscht werden, ohne die gesamte metallische Armatur auswechseln zu müssen.In addition, everyone can easy to connect with the plastic pipe directly related elements be replaced. For this purpose, only the holding device must be solved and the plastic sleeve is removable from the metal nozzle. This For example, it is advantageous if the weld between the plastic sleeve and the plastic pipe is faulty, for example because the plastic pipe is not careful enough for the welding process was prepared. Even if several welds are faulty should, so can repeatedly the corresponding plastic sleeves are exchanged, without having to replace the entire metallic fitting.
Durch die Anordnung der Kunststoffmuffe im Metallstutzen verkürzt sich auch die Baulänge der gesamten metallischen Armatur, was eine einfachere Handhabung, insbesondere auch in räumlich sehr begrenzten Baustellengruben zum Vorteil hat.By the arrangement of the plastic sleeve in the metal nozzle is shortened also the length the entire metallic fitting, allowing for easier handling, especially in spatial terms very limited site pits has the advantage.
Das Kunststoffrohr kann in die Kunststoffmuffe, welche in diesem Fall im Bereich der Innenwände über Heizdrähte verfügt, eingeführt und dort mittels dieser Heizdrähte verschweißt werden wie es auch bei Elektroschweißmuffen üblich ist. Dies hat den Vorteil, dass pro Nennweite des Kunststoffrohres nur noch eine metallische Armatur vorgesehen werden muss, da die Außendurchmesser einer Nennweite auch bei verschiedenen Wandstärken konstant sind.The plastic tube can be inserted into the plastic sleeve, which in this case has heating wires in the region of the inner walls, and welded there by means of these heating wires, as is also customary in electric welding sleeves. this has the advantage that only one metallic fitting must be provided per nominal width of the plastic tube, since the outside diameter of a nominal diameter are constant even with different wall thicknesses.
Bevorzugterweise sind die Heizdrähte bifilar angeordnet, wodurch die elektrischen Anschlüsse auf einer Seite – Idealerweise am äußeren Ende – der Kunststoffmuffe anordnenbar sind und nicht von dem Metallstutzen überdeckt werden. Dies ermöglicht einen besonders einfachen Zugriff auf die Heizdrähte, was den Verschweißvorgang erleichtert.preferably, are the heating wires arranged bifilar, eliminating the electrical connections one side - ideally at the outer end - the plastic sleeve can be arranged and not covered by the metal nozzle become. this makes possible a particularly easy access to the heating wires, what the welding process facilitated.
Alternativ kann das Kunststoffrohr auch mittels Stumpfschweißen an der Kunststoffmuffe angebracht werden. Dies ist besonders bei größeren Nennweite üblich. In diesem Fall benötigt man zwar für jede Wandstärke einer Nennweite eine eigene metallische Armatur; jedoch erübrigt sich für diesen Fall die Anbringung der Heizdrähte und der elektrischen Anschlüsse in der Kunststoffmuffe.alternative can the plastic pipe by butt welding to the Plastic sleeve to be attached. This is common especially with larger nominal width. In needed in this case one indeed for every wall thickness a nominal diameter of its own metallic fitting; however, it is unnecessary in this case the attachment of the heating wires and the electrical connections in the plastic sleeve.
Bei einer besonders bevorzugten Ausführungsform sind der Innenumfang des Metallstutzens und/oder der Außenumfang der Kunststoffmuffe zumindest bereichsweise leicht konisch ausgebildet. Hier hat sich ein Winkel von kleiner oder gleich 7° als günstig erwiesen. Bei einem solchen Winkel tritt Selbsthemmung auf. Außerdem ist die Abdichtung zwischen der Kunststoffmuffe und dem Metallstutzen hier besonders gut, da sich durch weiteres Einschieben der Kunststoffmuffe in den Stutzen der Anpressdruck an den Dichtmitteln erhöhen lässt, so dass eine besonders gut Abdichtung entsteht. Daher ist es auch sehr günstig, an dem konischen Bereich Dichtmittel, beispielsweise in Form von O-Ringen, vorzusehen.at a particularly preferred embodiment are the inner circumference of the metal nozzle and / or the outer circumference the plastic sleeve at least partially slightly conical. Here An angle of less than or equal to 7 ° has proved favorable. In such a Angle occurs self-locking. In addition, the seal between the plastic sleeve and the metal socket here particularly well because by further insertion of the plastic sleeve in the nozzle the contact pressure on the sealant can increase, making a special good sealing arises. Therefore, it is also very cheap to the conical region sealing means, for example in the form of O-rings, provided.
Um ein einfaches Einschieben der Kunststoffmuffe in den Metallstutzen zu ermöglichen, kann der Klemmring so ausgebildet sein, dass durch eine Verdrehung des Klemmringes die Kunststoffmuffe in den Metallstutzen hineingedrückt wird. Um dies zu realisieren, ist besonders die Ausbildung des Klemmringes als Bajonettverschluss geeignet. Wird der Klemmring dann in dieser Position gesichert, so entsteht eine dichte aber lösbare Verbindung zwischen der Kunststoffmuffe und dem Metallstutzen.Around a simple insertion of the plastic sleeve in the metal nozzle to enable the clamping ring can be designed so that by a rotation of the clamping ring, the plastic sleeve is pressed into the metal nozzle. To realize this, is particularly the formation of the clamping ring suitable as a bayonet lock. If the clamping ring then in this Secured position, creating a dense but detachable connection between the plastic sleeve and the metal nozzle.
