Abstract

1. Odour trap wherein, in a rectilinearly downwardly extending flow path (A-B) there is, pivotable about an axis (4) disposed outside the flow path (A-B) a flap (1) which, in the position of rest and under the action of a counterweight (5) which counteracts the force of gravity of the flap, bears on the underside of a seating (2) which is inclined obliquely downwardly in relation to the pivot axis (4) of the flap and which pivots downwardly when subjected to the loading of liquid striking it (1) from above, characterised in that the flap (1) and the seat (2) are disposed in a tubular main housing part (6) which is to be incorporated into the fluid pipe, in particular between a water outlet pipe and a sewer connecting pipe, the counterweight (5) being disposed in a housing projection (7) which is laterally adjacent the main housing part (6), and in that one half of the cross-section of the tubular main part (6) engages into the box-like housing projection (7) and in that the casing (13) of the tubular main part (6) in the housing projection (7) has a cut-out (15, 16) which extends over the half cross-section from the seat (2) as far as the bottom end (14) of the housing projection (7) and in that the housing projection (7) is tightly sealed by a removable cover (20) and in that the flap (1) together with the counterweight (5) can, once the cover (20) has been removed, be with-drawn from the housing (6, 7) so that a wire cleaning brush can be introduced through the housing projection (7) and into the cavity in the main housing part (6) which extends under the seat (2) and into the liquid pipe which is adjacent thereto.

Description

Die Erfindung bezieht sich auf einen Geruchsverschluss der im Oberbegriff des Patentanspruchs 1 angegebenen Gattung.The invention relates to an odor trap of the type specified in the preamble of claim 1.

Es ist ein Gully mit einem Geruchsverschluss dieser .Gattung bekannt (US-A-1 328103), bei dem im oberen Teil eines Betonkörpers ein Einlauftrichter und im unteren Teil ein Auslaufraum gebildet ist, der in Strömungsrichtung verjüngt ist und nach Art eines Rohrknies zu einer schräg abwärts verlaufenden Kanalisationsanschlussleitung führt. Die beiden Räume sind durch eine in den Beton eingebettete Metallplatte voneinander getrennt, die mit einer Oeffnung versehen ist, die an den Trichterausgang anschliesst. An der Oeffnung ist ein Rohrstück angesetzt, das in den Auslaufraum hineinragt und unten schräg abgeschnitten ist, wobei sein Rand den Sitz für die Klappe bildet. Der Auslaufraum ist neben dem Rohrstück erweitert, um dort die Klappenschwenkachse und das Gegengewicht aufzunehmen.A gully with an odor trap of this type is known (US-A-1 328103), in which an inlet funnel is formed in the upper part of a concrete body and an outlet space is formed in the lower part, which is tapered in the direction of flow and becomes one in the manner of a pipe elbow leads sewer connection line running downwards. The two rooms are separated from each other by a metal plate embedded in the concrete, which is provided with an opening that connects to the funnel exit. A piece of pipe is attached to the opening, which protrudes into the outlet space and is obliquely cut off at the bottom, its edge forming the seat for the flap. The outlet area is expanded next to the pipe section to accommodate the flap pivot axis and the counterweight.

Bei diesem bekannten Geruchsverschluss ist der Raum unterhalb des Sitzes verstopfungsanfällig und eine Reinigung ist praktisch kaum möglich. Zwar könnte z. B. eine Putzrute durch den Einlauftrichter und durch das Rohrstück hindurch eingeführt werden, beim Zurückziehen würde die Putzrute aber durch die Klappe in dem Rohrstück festgeklemmt. Darüber hinaus ist der Teil des Auslaufraumes, in dem die Klappenschwenkachse gelagert und das Gegengewicht angeordnet sind, überhaupt unzugänglich. Bei plötzlich erheblichem Ablaufwasseranfall oder bei einem Stau des Ablaufwassers können Schlamm oder Fremdkörper in diesen Raumteil gelangen und die Schwenkbarkeit der Klappe und damit deren Verschlusswirkung beeinträchtigen. Dabei könnte dieser Teil des Auslaufraumes neben dem Rohrstück auch dann nicht gereinigt werden, wenn eine Reinigung mit einer Putzrute im übrigen möglich wäre.With this known odor trap, the space below the seat is prone to clogging and cleaning is practically impossible. Although z. B. a cleaning rod through the inlet funnel and through the pipe section, but when pulling back the cleaning rod would be clamped by the flap in the pipe section. In addition, the part of the outlet space in which the valve pivot axis is mounted and the counterweight are arranged is inaccessible at all. If there is suddenly a considerable amount of waste water or if there is a build-up of waste water, sludge or foreign bodies can get into this part of the room and impair the pivotability of the flap and thus its locking effect. This part of the outlet space could not be cleaned next to the pipe section even if cleaning with a cleaning rod would otherwise be possible.

Hier will die Erfindung Abhilfe schaffen. Durch die Erfindung, wie sie im Patentanspruch 1 gekennzeichnet ist, wird die Aufgabe gelöst, einen Geruchsverschluss zu schaffen, der weniger zu Verstopfungen neigt und, falls trotzdem erforderlich, leicht und mühelos, z. B. mit einer Putzrute, vollständig und bis weit in die Kanalanschlussleitung hinein gereinigt werden kann. In den abhängigen Patentansprüchen sind besondere Ausführungsarten dieser Erfindung angegeben.The invention seeks to remedy this. By the invention, as characterized in claim 1, the object is achieved to provide an odor trap that is less prone to clogging and, if necessary, easily and effortlessly, for. B. with a cleaning rod, completely and can be cleaned well into the sewer connection line. Particular embodiments of this invention are specified in the dependent claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass Verschmutzungen den Geruchsverschluss besser passieren können, und dass die Herausnehmbarkeit der Klappe mit dem Gegengewicht eine mühelose, schnelle und vollständige Reinigung ermöglicht, indem z. B. eine Putzrute durch den den Bewegungsraum des Gegengewichts bildenden Gehäuseansatz, in dem auch die Schwenkachsenlager sind, in den Raum unter dem Sitz und weiter bis in die daran anschliessende Flüssigkeitsleitung, insbesondere Kanalanschlussleitung, geführt, hin und her bewegt und wieder zurückgezogen wird.The advantages achieved by the invention are essentially to be seen in the fact that dirt can pass through the odor trap better and that the removability of the flap with the counterweight enables effortless, quick and complete cleaning, for example by B. a cleaning rod through the movement space of the counterweight forming the housing approach, in which the pivot axis bearings are, in the space under the seat and further into the adjoining liquid line, in particular channel connection line, guided, moved back and forth and back again.

In folgenden wird die Erfindung im Zusammenhang mit ihrer vorzugsweisen Verwendung anhand von lediglich ein Ausführungsbeispiel darstellenden, teilweise nur schematischen Zeichnungen näher erläutert.In the following, the invention is explained in more detail in connection with its preferred use on the basis of drawings, which in some cases are only schematic and only show one exemplary embodiment.

  • 3 shows an axial cross section along the line III-III in FIG. 1.

Im gerade abwärts verlaufenden Strömungsweg A-B des dargestellten Geruchsverschlusses sind eine Klappe 1 und der dazu gehörende Sitz 2 angeordnet. Die Schwenkachse 4 der Klappe 1 (vergl. deren Zapfen 3 in Fig. 2) verläuft neben dem Sitz 2 ausserhalb des Strömungsweges A-B. Der Sitz 2 ist in Bezug auf die Klappenschwenkachse 4 schräg abwärts geneigt, d. h. in einer von der Schwenkachse 4 schräg abwärts verlaufenden Ebene angeordnet oder parallel zu einer solchen Ebene, je nach der Lage, welche die Schwenkachse 4 in Bezug auf die Klappenebene hat. Gegen die Schwerkraft der Klappe 1 wirkt ein Gegengewicht 6, dessen Massenmittelpunkt in Ruhelage der Klappe 1 annähernd auf derselben Höhe wie deren Schwenkachse 4 liegt. Die Klappe 1 kann zusammen mit ihrem Zapfen 3 und ihrem Gegengewicht 5 einstückig aus Metall bestehen.A flap 1 and the associated seat 2 are arranged in the straight downward flow path A-B of the odor trap shown. The pivot axis 4 of the flap 1 (see. The pin 3 in Fig. 2) runs next to the seat 2 outside the flow path A-B. The seat 2 is inclined downwards with respect to the flap pivot axis 4, i. H. arranged in a plane running obliquely downward from the pivot axis 4 or parallel to such a plane, depending on the position which the pivot axis 4 has with respect to the flap plane. A counterweight 6 acts against the gravity of the flap 1, the center of mass of which, when the flap 1 is at rest, is approximately at the same height as its pivot axis 4. The flap 1, together with its pin 3 and its counterweight 5, can be made in one piece from metal.

Das Gehäuse des Geruchsverschlusses, das aus Kunststoff oder Metall (Blech oder Guss) bestehen kann, hat einen rohrförmigen Gehäusehauptteil 6, in dem der geradlinige Strömungsweg A-B verläuft, und einen kastenförmigen Gehäuseansatz 7. Das obere Ende 8 des rohrförmigen Teils 6 ist an das (nicht dargestellte) untere Ende eines Wasserablaufrohres anzuschliessen. Das untere Ende 9 des rohrförmigen Teiles 6 ist dicht mit einer (nicht dargestellten) Anschlussleitung einer Kanalisation zu verbinden, so wie bei bekannten Geruchsverschlüssen üblich. Die Klappe 1 und der Sitz 2 sind im rohrförmigen Teil 6, das Gegengewicht 5 die Zapfen 3 und dazugehörige Zapfenlager 10 sind im Gehäuseansatz 7 angeordnet. Eine Querschnittshälfte des rohrförmigen Teils 6 greift zwischen die in Fig. 1 vordere und hintere Wand 11 und 12 des Gehäuseansatzes 7 hinein. Dabei hat die im Ansatz 7 veflaufende Mantelhälfte 13 des rohrförmigen Teils 6 eine Aussparung, die sich vom Sitz 2 bis zum Boden 14 des Ansatzes 7 über den halben Rohrumfang erstreckt so dass die Mantelhälfte 13 unterhalb des Sitzes 2 bis an den Boden 14 herausgeschnitten ist. Der obere Rand der Aussparung ist mit 15, der untere ist mit 16 bezeichnet.The housing of the odor trap, which can be made of plastic or metal (sheet metal or cast iron), has a tubular housing main part 6, in which the rectilinear flow path AB runs, and a box-shaped housing attachment 7. The upper end 8 of the tubular part 6 is connected to the ( not shown) to connect the lower end of a water drain pipe. The lower end 9 of the tubular part 6 is to be tightly connected to a sewer connection line (not shown), as is customary in the case of known odor traps. The flap 1 and the seat 2 are in the tubular part 6, the counterweight 5, the pin 3 and associated pin bearing 10 are arranged in the housing shoulder 7. A cross-sectional half of the tubular part 6 engages between the front and rear walls 11 and 12 of the housing extension 7 in FIG. 1. The jacket half 13 of the tubular part 6 running in the neck 7 has a recess which extends from the seat 2 to the bottom 14 of the neck 7 over half the circumference of the tube, so that the jacket half 13 is cut out below the seat 2 to the bottom 14. The upper edge of the recess is 15, the lower is 16.

Die obere Wand 17 des Ansatzes 7 ist mit einer Oeffnung 18 versehen, deren lichte Weite nicht wesentlich kleiner als die des rohrförmigen Teiles 6 ist. Die oeffnung ist durch einen mittels Schrauben 19 lösbar befestigten Dekkel 20 verschlossen wobei eine Dichtung 21 einen luftdichten Verschluss bewirkt. Die Lager 10 für die Zapfen 3 der Klappe 1 sind an der vorderen bzw. hinteren Ansatzwand 11 bzw. 12 angeordnete U-förmige Lagerschalen, aus denen die Zapfen 3 nach oben herausgehoben werden können. Dies ermöglicht es die Klappe 1 mit ihrem Gegengewicht 5 aus dem Gehäuse 6/7 bei abgenommenem Deckel 20 herauszunehmen, nachdem sie in die strichpunktiert dargestellte Lage geschwenkt wurde. Dazu ist der Abstand des Gegengewichts 5 von der Wand 22 des Gehäuseansatzes 7 so bemessen, dass man das Gegengewicht 5 in Schliesslage der Klappe 1 erfassen kann, um die Klappe 1 mit dem Gegengewicht 5 in die Offenstellung zu schwenken und herauszunehmen. Zu diesem Zwecke könnte das Gegengewicht 5 auch mit einer geeigneten (nicht dargestellten) Handhabe versehen sein.The upper wall 17 of the extension 7 is provided with an opening 18, the clear width of which is not significantly smaller than that of the tubular part 6 is. The opening is closed by a cover 20 which is detachably fastened by means of screws 19, a seal 21 effecting an airtight closure. The bearings 10 for the pins 3 of the flap 1 are U-shaped bearing shells arranged on the front and rear extension walls 11 and 12, from which the pins 3 can be lifted upwards. This enables the flap 1 with its counterweight 5 to be removed from the housing 6/7 with the cover 20 removed after it has been pivoted into the position shown in broken lines. For this purpose, the distance of the counterweight 5 from the wall 22 of the housing attachment 7 is dimensioned such that the counterweight 5 can be grasped in the closed position of the flap 1 in order to pivot the flap 1 with the counterweight 5 into the open position and to remove it. For this purpose, the counterweight 5 could also be provided with a suitable handle (not shown).

Ein Anschlag 23 begrenzt die oeffnungsbewegung der Klappe 1. Die Schenkel der U-förmigen Lagerschalen 10 können federnd sein und oben einen Abstand haben, der kleiner als der Durchmesser der Zapfen 3 ist, so dass diese nur unter Ueberwindung der Federkraft herausgehoben werden, sich aber nicht unerwünscht aus den Lagerschalen 10 lösen können, beispielsweise wenn eine grössere Wasserströmung unsymmetrisch auf die Klappe 1 trifft. Die Seitenwand des Gehäuseansatzes 7 verläuft anschliessend an den Wandteil 22 schräg abwärts (Wandteil 24) zum Boden 14 des Gehäuseansatzes 7 am unteren Rand 16 der Aussparung. Dabei hat der schräge Wandteil 24 von der Schwenkachse 4 der Klappe 1 einen Abstand, der nicht wesentlich kleiner als die lichte Weite des rohrförmigen Teils 6 ist. Der Wandteil 24 dient als Führung für eine Putzrute, die erforderlichenfalls zur Reinigung des unteren Teiles des Geruchsverschlusses und der mit dessen unterem Ende 9 verbundenen (nicht dargestellten) Anschlussleitung der Kanalisation eingeführt werden kann, nachden der Deckel 20 abgenommen und die Klappe 1 mit ihrem Gegengewicht 5 herausgenommen wurde.A stop 23 limits the opening movement of the flap 1. The legs of the U-shaped bearing shells 10 can be resilient and have a distance at the top that is smaller than the diameter of the pins 3, so that they are lifted out only by overcoming the spring force, but are lifted out cannot undesirably detach from the bearing shells 10, for example if a larger water flow hits the flap 1 asymmetrically. The side wall of the housing extension 7 then runs obliquely downwards on the wall part 22 (wall part 24) to the bottom 14 of the housing extension 7 at the lower edge 16 of the recess. In this case, the inclined wall part 24 is at a distance from the pivot axis 4 of the flap 1 that is not significantly smaller than the inside width of the tubular part 6. The wall part 24 serves as a guide for a cleaning rod, which, if necessary, can be introduced for cleaning the lower part of the odor trap and the sewer connection line (not shown) connected to its lower end 9, after which the cover 20 is removed and the flap 1 with its counterweight 5 was removed.

Abweichend vom gezeichneten Ausführungsbeispiel können die Zapfen 3 am Gehäuseansatz 7 und die Lagerschalen 10 an der Klappe 1 angeordnet sein, wobei die letzteren in Klappenruhelage mit der offenen U-Seite nach unten oder schräg nach unten zu richten sind, und der Abstand der Zapfen 3 von der Mantelhälfte 13 des rohrförmigen Gehäuseteils 6 so gross bemessen sein muss, dass die Lagerschalen 10 in der in Fig. 1 strichpunktiert gezeichneten Stellung der Klappe 1 von den Zapfen 3 abgezogen werden können.In a departure from the exemplary embodiment shown, the pins 3 can be arranged on the housing shoulder 7 and the bearing shells 10 on the flap 1, the latter being in the flap rest position with the open U-side pointing downwards or obliquely downwards, and the distance of the pins 3 from the jacket half 13 of the tubular housing part 6 must be dimensioned so large that the bearing shells 10 can be pulled off the pin 3 in the position of the flap 1 shown in broken lines in FIG. 1.

Bei der gezeichneten Ausführungsform verläuft der Sitz 2 an der Innenseite des rohrförmigen Gehäusehauptteils 6. Dadurch ist der lichte Querschnitt des Strömungsweges A-B im Bereich des Sitzes 2, in Strömungsrichtung gesehen, etwas kleiner als ober- und unterhalb des Sitzes 2. Um dies zu vermeiden, ist bei einer nicht gezeichneten Ausführungsform des Geruchsverschlusses die dem Gehäuseansatz 7 gegenüberliegende Umfangshälfte des rohrförmigen Hauptteils 6 mit einer Ausbuchtung versehen, und der Gehäuseansatz 7 ist der Ausbuchtung angepasst breiter ausgeführt, wobei eine Umfangshälfte des Sitzes in der Ausbuchtung und die andere Umfangshälfte unter dem unteren Rand der in Fig. 1 und 3 mit 13 bezeichneten Mantelhälfte des rohrförmigen Gehäusehauptteils angeordnet ist. Die Ausbuchtung ist unterhalb des Sitzes so zu bemessen, dass die Schwenkbarkeit der Klappe 1 gewährleistet ist. Dies ermöglicht es, einen Sitz zu verwenden, dessen lichte Oeffnung, in Strömungsrichtung A-B gesehen, mit dem lichten Querschnitt des rohrförmigen Gehäusehauptteils 6 übereinstimmt oder sogar grösser ist.In the illustrated embodiment, the seat 2 runs on the inside of the tubular housing main part 6. As a result, the clear cross section of the flow path AB in the region of the seat 2, viewed in the direction of flow, is somewhat smaller than above and below the seat 2. In order to avoid this, In a non-illustrated embodiment of the odor trap, the circumferential half of the tubular main part 6 opposite the housing extension 7 is provided with a bulge, and the housing extension 7 is designed to be wider than the bulge, with one circumferential half of the seat in the bulge and the other circumferential half below the lower edge the jacket half of the tubular housing main part designated 13 in FIGS. 1 and 3 is arranged. The bulge is to be dimensioned below the seat so that the pivoting of the flap 1 is guaranteed. This makes it possible to use a seat whose clear opening, as seen in the flow direction A-B, matches or is even larger than the clear cross section of the tubular housing main part 6.

Wenn eine geringfügige Verkleinerung des Strömungsquerschnitts im Bereich des Sitzes 2 in Kauf genommen werden kann, genügt es, den Sitz nur in Richtung quer zur Klappenschwenkachse 4 grösser auszuführen, und die Breite des Gehäuseansatzes 7 beizubehalten. Der Sitz ist dabei an seinem dem Gehäuseansatz 7 gegenüberliegenden etwa halben Umfang in der Ausbuchtung und dieser gegenüber am unteren Rand des in Fig. 1 und 2 mit 13 bezeichneten Randes der oberen Mantelumfangshälfte anzuordnen, er ragt nur an seinen einander parallel zur Klappenschwenkachse 4 gegenüberliegenden Teilen in den Strömungsweg hinein. .If a slight reduction in the flow cross-section in the area of the seat 2 can be accepted, it is sufficient to make the seat larger only in the direction transverse to the valve pivot axis 4 and to maintain the width of the housing extension 7. The seat is to be arranged on its approximately half circumference opposite the housing extension 7 in the bulge and opposite this at the lower edge of the edge of the upper circumferential half designated 13 in FIGS. 1 and 2; it only projects on its parts lying opposite one another parallel to the flap pivot axis 4 into the flow path. .
