Description

Die Erfindung bezieht sich auf ein Abwasserrohr mit Reinigungsöffnung und Rückstauklappe. Dabei wird die Reinigungsöffnung durch einen an einem Grundkörper angeformten Aufsatz gebildet, der durch einen Deckel verschlossen ist. Am Grundkörper sind einlaufseitig bzw. ablaufseitig Stutzen zum Anschluß der Abwasserleitung vorgesehen. Einlaufseitig ist im Grundkörper eine Rückstauklappe eingebracht.The invention relates to a sewage pipe with a cleaning opening and backflow flap. The cleaning opening is formed by an attachment molded onto a base body and closed by a cover. On the inlet or outlet side, connectors are provided on the base body for connecting the waste water line. A backflow flap is installed in the main body on the inlet side.

Abwasserrohre dieser Art werden in die Abwasserleitungen von Gebäuden eingebaut. Durch die Rückstauklappe soll ein Rückfluß von Wasser aus der Kanalisation vermieden werden. Die Reinigungsöffnung ermöglicht eine Reinigung des Grundkörpers hinter der Rückstauklappe. Von Fall zu Fall werden Abwasserrohre dieser Art auch mit zwei Rückstauklappen ausgerüstet, die jeweils eine zugeordnete Reinigungsöffnung haben. In besonderen Bedarfsfällen werden diese Abwasserrohre auch mit Einrichtungen versehen, in denen die Rückstauklappe in ihrer Schließstellung verriegelt werden kann. In Fällen, wo im Leitungssystem nur eine Reinigungsöffnung benötigt wird, kann der Grundkörper auch ohne RückstauklappE eingesetzt werden.Sewage pipes of this type are installed in the sewage pipes of buildings. The backflow flap is intended to prevent water from flowing back out of the sewage system. The cleaning opening enables the body to be cleaned behind the backflow flap. From case to case, sewage pipes of this type are also equipped with two backflow flaps, each with an assigned cleaning opening. In special cases, these sewage pipes are also provided with devices in which the backflow flap can be locked in its closed position. In cases where only one cleaning opening is required in the pipe system, the base body can also be used without a backflow valve.

Aus einem Prospekt "Univa-Staufix (Kessel KG)"ist ein Abwasserrohr der beschriebenen Art bekannt. Der Grundkörper dieses Abwasserrohres weist eine relativ große Baulänge auf, da die Stutzen angeformt sind und der Grundkörper für den Einbau von einer Rückstauklappe und wahlweise von zwei Rückstauklappen ausgelegt ist. Als Verriegelungsvorrichtung für die Rückstauklappe ist bei diesem bekannten Abwasserrohr ein zweiarmiger Hebel vorgesehen, für dessen Gelenklagerung im Deckel ein Hohlraum gebildet ist.A waste water pipe of the type described is known from a brochure "Univa-Staufix (Kessel KG)". The basic body of this sewage pipe has a relatively large overall length, since the nozzles are integrally formed and the basic body is designed for the installation of a backflow flap and optionally two backflow flaps. In this known sewage pipe, a two-armed lever is provided as a locking device for the backflow flap, for the articulation of which a cavity is formed in the cover.

Die Erfindungsaufgabe besteht in einer Vereinfachung des Grundkörpers im Hinblick auf eine wirtschaftliche Fabrikation bei einem Abwasserrohr mit Regulierungsöffnung und Rückstauklappe der eingangs genannten Art.The task of the invention is to simplify the basic body with regard to economical production in the case of a sewage pipe with a regulating opening and a backflow flap of the type mentioned at the beginning.

Die Lösung dieser Aufgabe besteht in einer Kombination folgender Merkmale:

  • Die Stutzen sind besonders hergestellte Formteile, die am Grundkörper angeschraubt werden können, wobei an den Stutzen einerseits und am Grundkörper andererseits Flansche zur Aufnahme von Befestigungsschrauben angeformt sind. Um die Einlauföffnung des Grundkörpers herum ist ein Dichtungsring gehalten, dem eine am Einlaufstutzen angeformte Widerlagerfläche zugeordnet ist. Um die Ablauföffnung des Grundkörpers herum, welche den gleichen Durchmesser wie die Einlauf Öffnung hat, ist außen eine Widerlagerfläche gebildet, für einen am Auslaufstutzen gehaltenen Dichtungsring. Am Grundkörper ist gleich hinter der Einlauföffnung ein Sitz für die Rückschlagklappe gebildet.
The solution to this task consists of a combination of the following features:
  • The nozzles are specially manufactured molded parts that can be screwed onto the base body, with flanges for receiving fastening screws being formed on the nozzle on the one hand and on the base body on the other. A sealing ring is held around the inlet opening of the base body and is associated with an abutment surface formed on the inlet connector. Around the outlet opening of the base body, which has the same diameter as the inlet opening, an abutment surface is formed on the outside for a sealing ring held on the outlet nozzle. A seat for the non-return valve is formed on the base body directly behind the inlet opening.

Bei dem Abwasserrohr nach der Erfindung ist der Grundkörper sehr einfach und von einer relativ kurzen Baulänge, weil die Stutzen nicht angeformt sind und weil er nur für eine Rückstauklappe ausgelegt ist. Entsprechend der Vereinfachung des Grundkörpers ergibt sich eine Vereinfachung der Spritzform und dem zufolge ein geringerer Kostenaufwand der Werkzeugkosten als dies bei Abwasserrohren nach dem Stand der Technik der Fall ist. Die Stutzen werden bei der Montage des Abwasserrohres angeschraubt, wofür angeformte Flansche und Befestigungsschrauben mit Muttern zur Verfügung stehen. Am Grundkörper sind der einlaufseitige Dichtungsring und die auslaufseitige Widerlagerfläche passend ausgebildet. Daher besteht die Möglichkeit, an einem ersten Grundkörper ausgangsseitig einen zweiten Grundkörper anzusetzen und anzuschrauben, wenn ein Abwasserrohr mit zwei Rückstauklappen benötigt wird. Der Übergang von den Stutzen in den Grundkörper und umgekehrt ist zumindest im Bodenbereich gerade, also ohne Absatz. Der Boden des Grundkörpers ist gegenüber dem Sitz der Rückstauklappe nach unten abgesetzt. Das Wasser kann also durchströmen, ohne einen nennenswerten Widerstand zu erfahren.In the sewage pipe according to the invention, the base body is very simple and of a relatively short overall length because the nozzles are not formed and because it is only designed for a backflow flap. In accordance with the simplification of the base body, there is a simplification of the injection mold and consequently a lower cost of the tool costs than is the case with sewage pipes according to the prior art Technology is the case. The sockets are screwed on when installing the sewage pipe, for which molded flanges and fastening screws with nuts are available. The sealing ring on the inlet side and the abutment surface on the outlet side are designed to match. It is therefore possible to attach and screw on a second base body on a first base body if a waste water pipe with two backflow flaps is required. The transition from the nozzle to the base body and vice versa is straight, at least in the floor area, that is to say without a step. The bottom of the body is set down from the seat of the backflow flap. The water can therefore flow through without experiencing any appreciable resistance.

Weil, gemäß der weiteren Erfindung, die Rückschlagklappe an einer einsetzbaren Leiste gelenkig befestigt ist, besteht die Möglichkeit im Bedarfsfalle auch ein Abwasserrohr in vereinfachter Form ohne Rückstauklappe zur Verfügung zu stellen.Because, according to the further invention, the non-return valve is articulated to an insertable bar, there is the possibility, if necessary, of providing a simplified sewage pipe without a non-return valve.

Gemäß der weiteren Erfindung wird zur Aufnahme der Leiste ohne Vergrößerung der Bauhöhe dadurch Raum gewonnen, daß der Sitzdurchmesser etwas geringer ist, als der Durchmesser der Einlauföffnung, wobei der Sitz unten auf gleicher Höhe ist wie die Einlauföffnung, oben jedoch etwas abgesetzt. Durch diese Anordnung bleibt die Bauhöhe des Abwasserrohres so gering wie möglich. Die Verringerung des Durchflußquerschnittes jedoch bleibt, da sie auf den oberen Durchflußbereich beschränkt ist, ohne nennenswerten Einfluß.According to the further invention, space is gained to accommodate the bar without increasing the overall height in that the seat diameter is somewhat smaller than the diameter of the inlet opening, the seat being at the same level as the inlet opening at the bottom but somewhat offset above. With this arrangement, the overall height of the sewage pipe remains as low as possible. The reduction in the flow cross-section, however, remains without any noteworthy influence, since it is limited to the upper flow range.

Das für den Durchfluß des Wassers erforderliche Gefälle bleibt auch im Bereich der Böden zweier aneinandergekuppelter Grundkörper erhalten, weil gemäß der weiteren Erfindung am Grundkörper die Ablauföffnung gegenüber der Einlauf Öffnung etwas nach unten abgesetzt ist.The gradient required for the flow of water also remains in the area of the bottoms of two coupled base bodies, because, according to the further invention, the drain opening on the base body is set down somewhat from the inlet opening.

Wenn für die Rückstauklappe eine Verriegelung gewünscht wird dann wird der Grundkörper mit einem Deckel ausgerüstet, der eine Verriegelungsvorrichtung nach der Erfindung aufweist. In einem solchen Deckel ist lotrecht verschieblich eine Stange gelagert, an der unten ein Riegel angebracht ist. Die Stange kann von außen betätigt werden. Wenn der Riegel mit Hilfe der Stange nach unten geschoben ist, wobei er an angeformten Leisten des Grundkörpers geführt ist, dann liegt er derart an der Rückstauklappe an, daß diese in der Verschlußstellung gehalten ist. Eine solche Ausführung einer Verriegelungsvorrichtung ist sehr einfach und erfordert keinen besonderen Aufbau oder Vergrößerungen des Deckels.If a locking is desired for the backflow flap then the base body is equipped with a cover which has a locking device according to the invention. In such a cover, a rod is slidably mounted, on which a latch is attached below. The rod can be operated from the outside. If the bolt is pushed down with the help of the rod, whereby it is guided on molded strips of the base body, then it lies against the backflow flap in such a way that it is held in the closed position. Such a design of a locking device is very simple and does not require any special construction or enlargement of the cover.

Im folgenden wird ein Ausführungsbeispiel der Erfindung beschrieben unter Bezugnahme auf die Zeichnungen.

In the following an embodiment of the invention will be described with reference to the drawings.
  • Fig. 1 shows a longitudinal section through a sewage pipe according to the invention with two backflow flaps.
  • FIG. 2 is a view of the main body of this sewage pipe in the direction II of FIG. 1
  • 3 is a plan view of the base body in the direction of arrow III of FIG. 2

Bei dem Abwasserrohr, wie es auf Fig. 1 dargestellt ist, ist ein Stutzen 20 an eine Abwasserleitung eines Gebäudes angeschlossen. Vom Stutzen 20 wird das Abwasser in einen Grundkörper 10 geleitet. Dieser Grundkörper ist mit einer Rückstauklappe 14 ausgerüstet, die vom Druck des zufließenden Wassers hochgeschwenkt wird, sodaß eine Einlauföffnung 16 des Grundkörpers mehr oder weniger geöffnet wird.In the sewage pipe, as shown in Fig. 1, a nozzle 20 is connected to a sewage pipe of a building. From the nozzle 20, the waste water is passed into a base body 1 0. This base body is equipped with a backflow flap 14, which is pivoted up by the pressure of the inflowing water, so that an inlet opening 16 of the base body is opened more or less.

Von dem Grundkörper 10 gelangt das Wasser in einen daran angeschlossenen zweiten Grundkörper 10' der ebenfalls mit einer Rückstauklappe 14 ausgerüstet ist. Die beiden Grundkörper 10 und 10' sind identisch. Über eine Ablauföffnung 18 im Grundkörper 10' fließt das Wasser in einen Ablaufstutzen 25, der an die häusliche Abwasserleitung angeschlossen ist.The water passes from the base body 10 into a second base body 10 'connected to it, which is also equipped with a backflow flap 14. The two base bodies 10 and 10 'are identical. Via an outlet opening 18 in the base body 10 ', the water flows into an outlet connection 25 which is connected to the domestic sewage line is closed.

Der Grundkörper 10 sowie der identische Grundkörper 10' weisen in ihrem unteren Bereich einen zylindrischen Querschnitt auf. Im oberen Bereich ist ein Aufsatz 11 angeformt, durch den eine in der Draufsicht rechteckige oder quadratische Reinigungsöffnung gebildet ist. Die Öffnung ist durch einen Deckel 12 abgeschlossen. Deckel und Grundkörper sind durch lösbare Schrauben miteinander verbunden. Die Schrauben sind durch Flansche 12a, die am Grundkörper bzw. am Deckel angeformt sind, gest-eckt.The base body 10 and the identical base body 10 'have a cylindrical cross section in their lower region. In the upper area an attachment 11 is formed, through which a cleaning opening which is rectangular or square in plan view is formed. The opening is closed by a cover 12. The lid and base body are connected to each other by removable screws. The screws are inserted through flanges 12a, which are formed on the base body or on the cover.

Ringsum die Einlauföffnung 16 des Grundkörpers ist außen eine Nut geformt, die einen weichen Dichtungsring 17 (Gummiring) aufnimmt. DiesemDichtungsring ist eine am Einlaufstutzen 20 angeformte Widerlagerfläche 21 zugeordnet. Die Verbindung zwischen dem Einlaufstutzen 20 und dem Grundkörper 10 wird ebenfalls durch.Schrauben hergestellt, zu deren Aufnahme an dem zu verbindenden Teil Flansche 10a bzw. 22 angeformt sind. Zur Zentrierung des Einlaufstutzens mit der Einlauföffnung 16 sind im Anschluß an die Widerlagerfläche 21 bzw. im Anschluß an die Nut, die den Gummiring aufnimmt, konische Flä-chen angeformt.A groove is formed on the outside around the inlet opening 16 of the base body, which receives a soft sealing ring 17 (rubber ring). An abutment surface 21 integrally formed on the inlet connection 20 is assigned to this sealing ring. The connection between the inlet connection 20 and the base member 1 0 is also produced durch.Schrauben, are molded to the receptacle on the member to be bonded flanges 10a and 22 respectively. To center the inlet connection with the inlet opening 16, conical surfaces are formed in connection with the abutment surface 21 or in connection with the groove which receives the rubber ring.

Am Grundkörper ist auslaufseitig eine kreisrunde Ablauföffnung 18 angeformt, vom gleichen Durchmesser wie die Einlauf Öffnung 16, jedoch etwas nach unten versetzt. Der Boden des Grundkörpers schließt direkt an diese Ablauföffnung an.A circular drain opening 18 is formed on the outlet body on the outlet side, of the same diameter as the inlet opening 16, but offset somewhat downwards. The base of the base body connects directly to this drain opening.

Außen ist um die Ablauf öffnung herum eine Widerlagerfläche 19 gebildet, mit den gleichen Abmessungen wie die Widerlagerfläche 21 des Einlaufstutzens. Auch die Widerlagerfläche 19 wird von einer angeformten konischen Fläche zur Zentrierung umgeben.Outside, an abutment surface 19 is formed around the drain opening, with the same dimensions as the abutment surface 21 of the inlet connector. The abutment surface 19 is also surrounded by a molded conical surface for centering.

Grundkörper 10 und Grundkörper 10' sind wie dargestellt miteinander verbunden, mit Hilfe von Verbindungsschrauben, die von den Flächen 10a aufgenommen werden.Base body 10 and base body 10 'are connected to one another as shown, with the aid of connecting screws which are received by the surfaces 10a.

Auch der Ablaufstutzen 25 ist in der gleichen Weise mit dem Grundkörper 10' verbunden., Die Abdichtung wird durch einen Dichtungsring 26 bewerkstelligt, der von einer am Stutzen 25 angeformten Nut aufgenommen ist. Die Innenfläche des Stutzens 25 schließt sich ohne Absatz an die Ablauföffnung 18 an.The drain connector 25 is also connected to the base body 10 'in the same way. The sealing is accomplished by a sealing ring 26 which is received by a groove formed on the connector 25. The inner surface of the sleeve 25 joins with no shoulder on the drain opening 1 8.

Am Grundkörper ist gleich hinter der Einlauföffnung 16 eine gleichfalls kreisrunde Sitzöffnung gebildet, deren Kreis aber einen etwas kleineren Durchmesser hat. Im Bodenbereich geht die Einlauföffnung jedoch absatzlos in die Sitzöffnung über. Oben ergibt sich der Übergang durch eine im Querschnitt keilfömige konische Fläche.An equally circular seat opening is formed on the base body immediately behind the inlet opening 16, but the circle of which has a somewhat smaller diameter. In the floor area, however, the inlet opening merges seamlessly into the seat opening. At the top there is the transition through a conical surface which is wedge-shaped in cross section.

Die Sitzöffnung wird durch einen angeformten Sitzring 15 umgeben, um den herum ein Gummiring 15a gehalten ist.The seat opening is surrounded by a molded seat ring 15 around which a rubber ring 15a is held.

Die Rückstauklappe 14 ist schwenkbar an einer Leiste 13 gelagert, die ihrerseits bei abgenommenem Deckel in eine Ausnehmung des Grundkörpers eingesteckt werden kann. Die Leiste 13 ist durch den Deckel gehalten. Die Rückstauklappe 14 ist so geneigt, daß sie auf Grund ihres Eigengewichtes am Gummiring 15a anliegt. Mit Hilfe eines Riegels 30 kann die Rückstauklappe 14 in ihrer geschlossenen Stellung verriegelt werden, was zur Folge hat, daß kein Wasser mehr über den Einlaufstutzen 20 in den Grundkörper einfließen kann. Der Riegel 30 ist an einer Stange 31 befestigt, die in einer Büchse am Deckel lotrecht beweglich geführt ist, und von außen betätigt werden kann. Auf Fig. 1 ist der Riegel 30 voll ausgezeichnet in seiner obersten Stellung dargestellt, wobei die Rückstauklappe frei ist. Durch nach unten drücken der Stange 31 wird der Riegel 30 in die gestrichelt gezeichnete Stellung gebracht, in welcher er an der Rückstauklappe 14 anliegt und diese fest hält. Diese Stellung kann durch angeformte Verrastungselemente fixiert sein. Der Riegel ist in Nuten 32 geführt, die (Fig. 3) am Grundkörper angeformt sind. Die Leisten des Grundkörpers sind durch Leisten im Deekel fortgesetzt.The backflow flap 14 is pivotally mounted on a bar 13, which in turn can be inserted into a recess in the base body when the cover is removed. The bar 13 is held by the lid. The backflow flap 14 is inclined so that it lies against the rubber ring 15a due to its own weight. With the help of a bolt 30, the backflow flap 14 can be locked in its closed position, with the result that no more water can flow into the base body via the inlet connection 20. The bolt 30 is attached to a rod 3 1 , which is guided vertically movably in a sleeve on the cover, and can be actuated from the outside. In Fig. 1, the latch 30 is shown fully excellent in its uppermost position, the backflow flap is free. By pushing down the rod 31, the bolt 30 is brought into the position shown in broken lines, in which it rests on the backflow flap 14 and holds it firmly. This position can be formed by Locking elements to be fixed. The bolt is guided in grooves 32 which (FIG. 3) are formed on the base body. The strips of the basic body are continued by strips in the Deekel.

Der Boden des Abwasserrohres weist im Anschluß an den Sitzring 5 eine stärkere Neigung als.dahinter im Anschluß an die Ablauföffnung 18 auf. Die Strömung im Bereich der Rückstauklappe wird dadurch vergrößert und das Wegspülen von Ablagerungen begünstigt. Wenn der Riegel 30 in seiner unteren Stellung an der Rückstauklappe 14 anliegt, dann besteht eine Verrastung zwischen einer Ausnehmung 30a, die am Riegel gebildet ist, und einem entsprechenden Nocken 14a an der Rückstauklappe. Diese Verrastung hebt sich selbsttätig auf, wenn der Riegel nach oben bewegt wird. Die Rückstauklappe kann dabei etwas folgen, da sie in ihrem Gelenk an der Leiste 13 in lotrechter Richtung etwas Spiel hat. Die Rückstauklappe kann, wenn sie längere Zeit geschlossen ist, am Gummiring 15a festkleben. Durch eine geringfügige lotrechte Bewegung soll sich die Rückstauklappe vom Gummiring lösen, ohne daß sich der Gummiring seinerseits vom Sitzring abhebt.The bottom of the sewage pipe has a greater inclination after the seat ring 5 than behind it after the drain opening 18. This increases the flow in the area of the backflow flap and favors the washing away of deposits. When the latch 30 bears against the backflow flap 14 in its lower position, there is a latching between a recess 30a which is formed on the bolt and a corresponding cam 14a on the backflow flap. This latching is canceled automatically when the bolt is moved upwards. The backflow flap can follow something because it has some play in the vertical direction in its joint on the bar 13. The backflow flap can stick to the rubber ring 15a if it is closed for a long time. The backflow flap should come loose from the rubber ring by a slight vertical movement without the rubber ring itself lifting off the seat ring.
