Definitions

  • the invention relates to the use of a cleaning tube of the type specified in the preamble of claim 1.
  • Such cleaning pipes were previously usually used in the continuous pipeline, for example in the basement, whereby there was always access to the cover and, after its removal, to the inspection shaft through an inspection shaft covered on the top. If it became necessary later, e.g. B. due to overloading the sewer network or to protect the building or when installing a sewage lifting system to install a shut-off device, then the built-in cleaning pipe had to be removed with considerable effort and replaced by a cleaning pipe with at least one backflow stopper. This required considerable construction effort. If it became necessary at a later point in time, e.g.
  • Backflow devices for faecal-free sewage contain at least one operational closure in the form of a backflow shut-off flap, which keeps the line closed in the normal state and closes even more tightly in the event of a backflow due to the water pressure, but opens automatically again after the backflow has ended and when water flows in the direction of the drain.
  • Backflow stopper must contain an emergency stopper, with which the line can also be arbitrarily closed by actuation.
  • This emergency seal is also usually formed by a backflow valve. Not all countries require this emergency closure.
  • the on-site effort to convert from one sewage system to the other is expensive and labor intensive for the client.
  • the invention has for its object to provide a cleaning pipe of the type mentioned, with which any on-site effort to convert to the various sewage systems for the client is avoided.
  • the object is achieved according to the invention with the features specified in the characterizing part of protection claim 1.
  • the two kits can be converted to a different sewage system at any time, i.e. for faecal-free wastewater with a backflow risk and for faecal-containing wastewater with a backflow risk, without the need for changes on site. It is only necessary to remove the sealing cover from the cleaning tube and to insert the respective kit into the base body in order to meet the new requirements in a simple and quick manner. This is not only cost-effective for the client and involves little work, but also for the wholesaler, where the inventory is simplified, since the basic body is the same for all sewage systems and only the kits are different from one another.
  • kits are designed so that either the standard regulations applicable in the Federal Republic of Germany or the regulations in other countries are met, i.e. that either an operating lock and an emergency lock or only one operating lock for the respective sewage system is included in the kit.
  • the backflow shutters of the first kit thus meet the requirements of DIN 1997, because the two backflow shutters automatically react to backflow close, but after the backflow has ended, open it again without outside influence.
  • the backflow shut-off flap or the flaps of the second kit are coupled with a rotary actuator, so that they are kept in the open position in accordance with the DIN regulations in the operating position and are only closed in the event of a backflow.
  • the embodiment according to claim 3 is specially tailored to the DIN standards in the Federal Republic of Germany. Theoretically, more than two backflow shutters could also be provided for each cover. However, two are sufficient for the requirements that arise in practice.
  • kits include insert parts that form the sealing seats for the backflow shutters so that the tightness requirements are easily met. Basically, it would be conceivable to provide the cleaning pipe with the basic body in the basic concept with molded sealing seats, in which case no insert parts are then required. That would mean that stop surfaces for the closure flaps are firmly molded into the base body.
  • the insert parts have the advantage that they can be removed even after a long period of operation and, if necessary, replaced or cleaned with new ones.
  • back-pressure flaps on the insert part can be pivoted, preferably lifted out, because this ensures simple and functionally reliable attachment of the back-pressure flaps, which can even be removed and no special storage on the base body or on the cover.
  • the feature of claim 5 is also important because it eliminates the need for additional position securing parts for the insert parts or backflow flaps, and on the other hand the removable parts are immediately obtained when the cover is removed.
  • the lid presses on the insert and covers it shoulder-like for better securing of the position.
  • a safe function with a good sealing effect is achieved in the embodiment according to claim 6.
  • the angle lever offers a heavy weight shift for automatic closing and particularly favorable turning conditions.
  • an externally actuable mechanical and / or electromotive drive is provided in the closure cover of the first kit for the intended closure and, if necessary, lifting of at least one backflow closure flap.
  • This drive acting on the backflow valve is intended for the so-called emergency closure, which can be closed arbitrarily in the event of a backflow. Since the drive is also able to ventilate the backflow flap after the end of the backflow situation, there is no risk that the backflow flap will stick and no longer function properly if there is a long backflow.
  • the embodiment of claim 10 is also expedient, which relates to a sewage system containing faeces, in which at least one backflow flap is automatically moved from the operating position into the closed position via the liquid sensor when a backflow occurs.
  • the base body 2 On the inlet side, the base body 2 has a connection piece 8, while a connection piece 6 is provided on the outlet side.
  • a stump end 9 and a pointed end 7 are connected to the connecting pieces 8 and 6, for example by means of tensioning straps, in order to be able to replace and vary them.
  • the cleaning tube 1 in one piece with the parts 7 and 9.
  • a cover 10 is removably attached and sealed by seals. By lifting the cover 10 you have free access to the inspection shaft 3 and can clean the line unhindered.
  • the cleaning pipe 1 is equally suitable for sewage containing faeces and free of faeces. In the event of a backflow, however, the wastewater backing up from the draining sewer system can reach the connected devices via the cleaning pipe and exit. To prevent this, the cleaning pipe 1 of FIG. 1 is designed such that a backflow device for faecal-free waste water can be used as a first kit A according to FIG. 2.
  • a backflow device for faecal-free waste water can be used as a first kit A according to FIG. 2.
  • This consists of a cover 11, which corresponds with its edge dimensions to that of the cover 10 of FIG. 1, and a first backflow valve 12 and one in Distance behind arranged second backflow flap 13.
  • the cleaning pipe 1, provided that 2 sealing seats are attached or molded in the base body, to create a backflow device for faecal-free waste water.
  • the two backwater closure flaps 12 and 13 are at least functionally connected to the closure cover 11 in a manner not emphasized, ie, if necessary, molded onto it or attached to it. However, it is also conceivable to provide the two backflow shutters 12 and 13 separately from the cover 11 as separate insert parts.
  • the second backwater closure flap 13 with its drive to be explained later can be omitted, as is indicated by the dash-dotted line x.
  • the cover 11 would then look exactly the same in its right half in FIG. 2 as the cover 10 according to FIG. 1.
  • the backflow closure flap 12 has a pivot axis 14 for an L-shaped angle lever 16, to which a disk-shaped flap body 17 with a peripheral seal 18 is attached.
  • the pivot axis 14 can be arranged in a bearing 15, which is either attached to the closure cover 11 or separated from it. The pivot axis 14 can be conveniently lifted out of the bearing 15.
  • the second backflow flap 13 is substantially the same as the first flap 12. Its pivot axis is arranged in a bearing 19.
  • a pressure cam 20 is formed on its angle lever, which has an upper pressure surface and lateral ears 22.
  • a shaft with a square 24 is rotatably mounted, on which a locking cam 21 is arranged, which can cooperate with the pressure surface on the pressure cam 20 and has projections 23 which engage under the ears 22 in a certain rotational position of the square 24, to vent the backflow flap 13.
  • a hand-operated lever 25 is connected to the shaft carrying the square 24 and can be moved back and forth between the positions highlighted by a double arrow. In the position of the hand lever 25 shown in solid lines, the backflow valve 13 locked in their closed position. In the position of the hand lever 25 shown in dash-dotted lines, the backflow valve 13 is freely pivotable.
  • An electromotive drive could also act on the shaft carrying the square 24, so that the emergency actuation of the backflow valve 13 could also be carried out remotely.
  • the cleaning pipe 1 according to FIG. 1 is converted with a second kit B according to FIG. 3, which has a cover 26 corresponding in outline to the cover 10 of FIG. 1. Furthermore, the second kit B included a first backflow valve 27 and a second backflow valve 28, which functionally cooperate with the cover 26 provided at a sufficient distance from one another.
  • Both backflow stop covers 27 and 28 can be attached or attachable to the closure cover 26 or can also form separate insert parts which can be inserted into the inspection shaft 3 of the cleaning tube 1. Provided that appropriate sealing seats are attached or can be inserted in the cleaning shaft 3 of the base body 2, the two backflow shutters 27 and 28 then work together with these sealing seats as backflow closures.
  • the backflow flap 27 in the second kit B according to FIG. 3 has a pivot axis 29 for a pivot lever 30 which is integrally connected to a valve body 34 and contains a guide curve 31 which cooperates with a control member 32 which belongs to a rotary drive 33 which is housed in the closure cover 26.
  • a pot-shaped, elastic sealing element 35 is attached to the valve body 34, which contains a stiffening plate 36 and defines a cavity 37.
  • the backflow shutters 27 and 28 are held in the raised position shown in FIG. 3, because according to the standard regulations the backflow shutters for sewage containing faeces must be open in the normal operating position.
  • a liquid sensor 38 is attached to the closure cover 26 and connects to a control device (not shown) via a signal line that is.
  • the rotary drive 33 is connected to the control device via a line 40.
  • the backflow flap 28 corresponds essentially to the backflow flaps 12 and 13 of FIG. 2. The only difference is that its angle lever 43 is in positive connection via a joint 42 with a pivot cam 41, which is on the square carrying and by means of a hand lever 45 rotatable shaft sits.
  • the second backflow valve 28 with its rotary drive can also be omitted if the respective local requirements only require a single backflow valve 27.
  • the closure cover 26 would then be formed in its right half in FIG. 3 corresponding to the closure cover 10 of FIG. 1.
  • the cleaning pipe 1 of Fig. 1 is converted by means of the first kit A to a backflow stop 1A for faecal-free waste water.
  • the pivot axis 14 of the backflow closure flap 12 is mounted in an upper part 47 of an insert part 48, which is inserted from above into the inspection shaft and secured in position on a seat 50 formed there.
  • the closure cap 11 is placed on the upper part 47 from above and in this way secures the insert part 48 against being pushed out and shifting laterally.
  • the insert part 48 forms a sealing seat 49 for the backflow closure flap 12.
  • an insert 54 is inserted from above and fixed on a seat 51 formed in the base body 2, which forms a sealing seat 55.
  • the upper part of the insert part 54, designated 53, is fixed from above by the closure cover 11.
  • the backflow valve 13 is locked in its emergency closed position, while the backflow valve 12 can pivot freely.
  • FIG. 5 is a backflow from a base body 2 'already explained with reference to FIG. 1' with integrally molded tip end 7 'and stump end 9'.
  • the second kit B is expanded compared to the embodiment of FIG. 3 by insert parts 57 and 61, which form sealing seats 59 and 62 for the two backflow flaps 27 and 18.
  • the insert 57 is supported with a projection 58 on the bearing 50 of the base body 2 'and is secured from above on its upper part 56 by the cover 26.
  • the sealing seat 59 is formed here by a wide foam rubber or soft rubber seal, which cooperates excellently with the cup-shaped sealing element on the backflow flap 27, in order to ensure a perfect sealing seat even with impurities or solid parts jammed between them.
  • the insert part 61 is also fixed from above over its upper part 60 by the closure cover 26 and pressed onto a seat 51 in the base body 2 '.
  • the seats 50 and 51 are otherwise provided in the base body 2 of the cleaning tube 1 according to FIG. 1 from the outset.
  • the pivot axes of the two backflow shutters 27 and 28 are mounted in the embodiment according to FIG. 5 on the upper parts 56 and 60 of the insert parts 57 and 61, respectively.
  • Fig. 5 the backflow device 1B 'for faecal wastewater is shown in its normal working position, in which the two backflow shutters 27 and 28 are held in their open position. If a backflow now occurs, this is determined by the liquid sensor 38 and controls the drive 33 via the control device (not shown) so that it swivels the backflow shut-off valve 27 into its closed position and prevents the waste water from being pushed back beyond the stump end 9 '.
  • the second backflow closure flap 28 can also be brought into the closed position by hand using the handle 45 (emergency closure). It would also be conceivable to operate the second backflow valve 28 remotely with an electric motor drive.
  • the individual components of the embodiments of FIGS. 1 to 5, with the exception of the shafts, drives and seals, consist of a wastewater-resistant plastic, of die casting, of light metal or of cast iron.
