Definitions

  • the invention relates to a backflow closure according to the preamble of patent claim 1.
  • a backflow trap disposes of waste water by gravity over the downhill slope with the shut-off element in the open position directly into the sewage system.
  • the shut-off In a backwater situation, the shut-off is in the closed position, or by influencing a user, so that wastewater is no longer disposable via the downgrade directly into the sewer, but bypassing the shut-off by a pump in the process and from there into the sewer is pumped, wherein the present backwater is prevented by the shut-off on entry into the building, provided that the sudströmweg by the pump is properly shut off. Only in this case, energy must be used to drive the pump.
  • a lifting system does not contain a shut-off element, but the delivery side of a pump is permanently connected to a backflow loop, which optionally runs upwards via the backflow level and then to the sewage system.
  • Accumulating wastewater regardless of whether there is a backwater situation or not, can not be disposed of by the influence of gravity, but only by means of the pump. This means increased energy consumption for the pump, but has the advantage that in a backwater situation there is no danger that the backwater will enter the building.
  • a power failure or a malfunction of the pump there is a risk that wastewater can not be disposed of, but will lead to internal flooding in the building.
  • a backflow trap the wastewater disposed of by gravity over the slope directly into the sewer, in a backwater situation in shut-off befindlichem shut-off pumping wastewater through the pump directly into the sewer, but can be operated by a pressure pipe knee plugged onto the drain even as a lifting system and then accumulating wastewater, regardless of whether there is a backwater or not, only via the pressure tube knee pump up, is out EP 2 154 300 A1 known.
  • the pressure tube elbow no gravity disposal over the downslope in the channel longer possible. This requires significantly increased energy consumption, to dispose of any accumulating wastewater, the pump must be turned on, and then has to overcome the additional dynamic pressure level in the pressure tube knee.
  • the invention has for its object to provide a backwater valve of the type mentioned above, which is universally different needs of users, that is, a user with increased security needs the operation with sewage lifting function and security against the ingress of backwater into the building with higher Can provide energy expenditure, however, allows a user with lower security needs the operation in a backwater situation with a pumping function from the process directly into the sewer and with low energy consumption, while, as long as no backwater situation, using the sewage lifting function or the direct Abpumpfunktion the advantage Gravity disposal should be given without energy input.
  • the reverse flow connection of the backflow stopper offers the possibility of disposing of wastewater arising in a backwater situation via a backflow loop, and thus the increased safety standard of a lifting system.
  • This advantage is paired with the still given possibility of waste water on the downgrade only by gravity and without disposing of energy requirements, as long as there is no backflow situation.
  • the backflow stopper offers the user, with an exchange between the discharge nozzles, the choice between the very safe sewage lifting function and the somewhat less secure direct pumping function in a backflow situation.
  • the discharge nozzle which connects the delivery side of the pump with the remindsleyleifen connection, exchanged for another discharge nozzle, which connects the delivery side of the pump with the downgrade or the drain of the backflow stop, downstream of the shut-off.
  • the backflow stop can be retrofitted before installation or even when installed.
  • the gravity disposal accumulating wastewater remains possible as long as no backwater situation occurs. The user or an installer can thus realize the particular desired solution with essentially the same basic equipment of the backflow closure. As long as no backflow situation exists, or the shut-off is not intentionally brought into the closed position, there is always the possibility of gravity disposal without energy needs.
  • the backflow loop connection connected to the discharge port is connected to a backflow loop of a building wastewater disposal system connected to a sewage system. If the discharge side of the pump in the direct discharge function via the other discharge port connected to the slope, with a backwater, the pump with lower energy consumption is operable because no congestion level must be overcome.
  • the backflow loop can extend upwards beyond the backflow level of the building-wastewater disposal system, so that it is also ruled out in the event of a backwater situation that wastewater is pushed back into the backflow closure via the backflow loop.
  • the backflow loop does not need to lead directly into the sewage system or a pipe of the sewage system, but can run inside the backflow trap in its drain.
  • the shut-off is a relative to the seat swinging hinged flap. Sewage can lift the flap by the flow pressure from the seat and drain. If no sewage arrives, the flap keeps its closed position automatically, so that no bugs or channel odors penetrate into the building. If a backwater situation occurs, then the damper also closes due to the backwater, so that the backwater does not enter the building can reproduce. Then, however, the pump must be switched on for disposal of wastewater.
  • the flap is additionally mechanically and / or manually and / or motor in the closed position and / or open position and brought in this durable.
  • the backflow loop connection of the backflow closure is arranged either in a side wall or inside the side wall of the main body.
  • the backflow loop is connected to the connection or a backflow loop can be connected. If the sewage lifting function is not desired or required, the return loop port can be closed by, for example, a plug, and the gravity discharge backflow stopper, bypassing the shut-off element, will flow into the downgrade or drain directly from there operated the sewer.
  • the discharge nozzle is removable with quick release caps installed on the delivery side and at the backflow loop port.
  • Clamping-iron closures that are manually operable without the aid of tools, for example for cleaning or maintenance, are particularly suitable here.
  • the delivery side of the pump may be connected via the discharge ports to both the return loop port and the downstream side of the shut-off element in the downgrade path.
  • a mechanically or motor actuated pump path switching device This may be a valve arrangement, a flap arrangement or a tap arrangement, for example.
  • This basic equipment of the backflow stop with the discharge nozzle allows an installer or user at any time to set him just appropriate disposal function, that is, either the sewage lifting function or the direct pumping function, but always paired with the foreign energy free gravity disposal.
  • the main body of the backflow closure comprises an intermediate part covering the downward gradient, in which the pump and, preferably, a flap actuating device are provided, and on the intermediate part a top part defining a bottom sealing plane, in whose side wall the backflow loop connection is located, and which, preferably, has an overhead insertion collar for a top piece.
  • This embodiment is suitable, for example, for incorporation into a basement sole, wherein the backflow loop then used with its initial region is also at least installed in the basement sole and connected to the return loop connection.
  • the top piece compensates for the height difference to the bottom level of the basement sole.
  • the main body is designed as a shaft channel, and the main body comprises a gradient section covering the intermediate part, in which at least one pump and, preferably a flap actuator are provided.
  • the shaft wall of the upwardly extending shaft is placed, or connected thereto, wherein the remindshielleife, preferably, extends within the shaft and is guided downstream of the flap back into the body or the drain.
  • two parallel pumps may be provided in the intermediate part, which are each connected on the conveyor side to a backflow loop (redundancy principle in the event of a pump malfunction).
  • a backflow flap is arranged in the region of the backflow loop connection. Specifically, when the backflow stopper is operated with the sewage lifting function, the backflow flap during maintenance or cleaning ensures that no wastewater remaining in the backflow loop in the rising part flows back from the backflow loop port when the pressure port is disconnected.
  • a shut-off valve for example for a shaft, a shut-off valve, preferably manually or by way of a motor, can be provided for similar reasons in the respective pressure port.
