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 section 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 instead 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 sewer 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.
  • Backflow closures which either either dispose of the wastewater under gravity over the gradient directly into the sewer system, and pump in a backwater situation with shut-off located in the closed position via the pump into the sewer, or operated as a lifting system and wastewater, regardless of a backwater situation, via a backflow loop pump into the sewer system, are known ( EP 2 154 300 A1 . Fig. 2 and Fig. 1 ; EP 1 035 262 A2 . DE 33 13 458 A1 . Page 9).
  • disposal by means of the pump is possible only via the outlet of the backflow stopper and directly into the channel or via the outlet and the backflow loop into the channel.
  • the invention has for its object to provide a backwater valve of the type mentioned, which is indeed operable with a sewage lifting function, but with low energy requirements.
  • Part of the task is also to create a backwater valve that is universally different user requirements, that is, a user with increased safety needs allows operation with the sewage lifting function, however, a user with lower safety requirements, the operation with the gravity disposal and a draining function from the drain directly into the sewer system allows, always the advantage of gravity disposal should be given without energy use, as long as there is no backwater situation.
  • the reverse flow connection of the backflow stopper offers the optional or permanent option of disposing of wastewater from the backflow loop in a backwater situation, and thus the increased safety standard of a lifting system.
  • this advantage is always paired with the still given possibility to dispose of waste water on the downgrade only by gravity and without energy needs, as long as no backwater situation exists.
  • increased safety standard of the backflow stopper in operation only energy is required for driving the at least one pump, if this is denied by either a backwater situation or by the user intentional gravity disposal. Even in the case a pump failure or power failure, the disposal of wastewater thus remains possible as long as no backwater situation occurs.
  • 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 flap also closes due to the backwater, so that the backwater can not propagate into the building. 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.
  • a user may bring the flap deliberately in the closed position and block in this before prolonged absence, or the flap is automatically brought in the event of a backwater situation, determined by appropriate sensors, in the closed position and blocked in this, the risk of pushing back To capture wastewater in the building. It may also be expedient to bring the flap, as long as there is no backflow situation, in the open position and hold in this, so that accumulating water flows undisturbed only by gravity with the least possible resistance and impurities contained therein and the flap is not inadmissible heavily polluted ,
  • 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 backflow loop connection can be closed, for example by a plug, and the backflow trap with gravity disposal and a normal pump disposal bypassing the shutoff in the downgrade or in the drain and from there directly into the sewer operated.
  • 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.
  • a particularly important idea of the invention is that the possibility of gravity disposal always bidding backwater between the wastewater lifting function and downstream of the shutoff directly into the downgrade or the drain disposal wastewater pumping function is convertible or convertible.
  • the backflow stopper thus offers the user the choice between the very safe sewage lifting function and the somewhat less secure direct pumping function, in each case in the event of a backflow situation or if a user deliberately brought the shut-off element into the closed position. 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 discharge nozzle which runs from the pump delivery side to the backflow loop connection, can be exchanged for another discharge connection which connects the delivery side of the pump with the downward slope or the outlet of the backflow closure, downstream of the shut-off element.
  • the user or the installer can retrofit the backwater valve before installation, or retrofit even in the installed state, by exchanging a pressure port for the other pressure port and the respectively unnecessary port is closed.
  • the delivery side of the pump can be connected to the backflow loop connection as well as to the downstream side of the shutoff element in the downward gradient via pressure connection.
  • a mechanically or motor actuated pump path switching device This may be a valve arrangement, a flap arrangement or a tap arrangement, for example.
  • the backflow loop connection of the backflow closure can be connected or connectable to a backflow loop of a building wastewater disposal system connected to a sewage system.
  • the backflow loop extends, preferably up to above the backflow level of the building-wastewater disposal system, so that even in the case of a backwater situation is excluded that wastewater is pushed back into the backflow through the backflow loop.
  • the backflow loop may only lead upwards over a limited height, and not necessarily beyond the backflow level. Nevertheless, then the risk is very low that a backwater pushes back wastewater on this backwater level, or is ensured by appropriate check means that no wastewater is pushed back in a backwater situation to the delivery side of the pump.
  • the backflow loop could not lead directly into the sewer or a pipe of the sewer, but within the backwater stopper only in its expiration.
  • 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 backflow loop, preferably, extends within the shaft and downstream of the flap is guided back into the main body or the drain.
  • two parallel pumps may be provided in the intermediate part, each being connected to a backflow loop on the delivery side (redundancy principle in the event of a pump malfunction).
  • a backflow flap are arranged on the delivery side, preferably in the respective discharge port, and / or in the region of the return flow loop connection. Specifically, when the backflow stopper is operated with the sewage lifting function, the backflow damper during maintenance or cleaning ensures that wastewater remaining in the backflow loop in the rising part can not flow 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.
