Definitions

  • 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.
  • 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.
  • 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.
  • sewage pipes of this type are also equipped with two backflow flaps, each with an assigned cleaning opening.
  • these sewage pipes are also provided with devices in which the backflow flap can be locked in its closed position.
  • the base body can also be used without a backflow valve.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the base body is equipped with a cover which has a locking device according to the invention.
  • 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.
  • 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.
  • 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.
  • the base body 10 and the identical base body 10 ' have a cylindrical cross section in their lower region.
  • 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.
  • 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 ist.steren, are molded to the receptacle on the member to be bonded flanges 10a and 22 respectively.
  • conical surfaces are formed in connection with the abutment surface 21 or in connection with the groove which receives the rubber ring.
  • 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.
  • 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.
  • 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.
  • 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.
  • the seat opening is surrounded by a molded seat ring 15 around which a rubber ring 15a is held.
  • 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.
  • the bolt 30 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.
  • 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.
  • 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.
