Description

The invention relates to a backflow closure according to the preamble of patent claim 1.

In wastewater disposal technology, for example buildings, a distinction is made between a backflow trap and a lifting system. 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. 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 Rückströmweg by the pump is properly shut off. Only in this case, energy must be used to drive the pump. As a rule, 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. In the event of 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. For this purpose, however, it is known to provide either an emergency power supply and / or redundantly a second pump.

At out DE 93 04 676 U1 and DE 200 02 931 U1 known, generic backflow seals each leads the Rückstauschleife connected to the delivery side of the pump discharge nozzle with check valve to drain the backwater stopper. A direct pumping function in the sequence is not given, which requires higher energy consumption for overcoming the congestion level in the backflow loop for the pump. The pump needs to be operated only in a backwater, since the sewage gravity disposal is given as long as there is no backwater.

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. However, with the use of 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.

At one off US 4,272,640 A known backwater valve, the delivery side of the pump via a welded, two-piece elbow is connected to the drain, wherein on the delivery side of the pump, a flap-check valve is provided. Since the elbow does not run above the delivery side, the pump in the elbow does not need to overcome a damming height, so that it can be operated with less energy consumption in this direct wastewater pumping function. In a backwater situation, however, there is no assurance that the backwater is not pushed back through the check valve and / or the pump into the building, because deposits and / or structural conditions of the check valve and / or the pump does not allow proper shut-off under all operating conditions can.

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 stated object is achieved with the features of claim 1.

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. As a result, with increased safety standard of the backflow stopper, only energy for driving the at least one pump is required during operation when gravitation disposal is either denied by a backflow situation or by the user. However, 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. Suitably, the discharge nozzle, which connects the delivery side of the pump with the Rückstauschleifen 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. Depending on the user's request, the backflow stop can be retrofitted before installation or even when installed. However, even in the case of a pump failure or power failure, 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. If the sewage lifting function is desired, 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.

Suitably, 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. Preferably, the flap is additionally mechanically and / or manually and / or motor in the closed position and / or open position and brought in this durable. Thus, for example, a user before prolonged absence deliberately bring the flap in the closed position and block in this, 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 ,

In an expedient embodiment, 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.

Conveniently, 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.

Alternatively, 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. To switch between the sewage lifting function and the direct pumping function is 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.

In an expedient embodiment, 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.

In an alternative embodiment of the backflow closure, which is intended here for installation in a sewer manhole either in the building or outside the building, 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. On the base body in the form of the channel channel the shaft wall of the upwardly extending shaft is placed, or connected thereto, wherein the Rückstauschleife, preferably, extends within the shaft and is guided downstream of the flap back into the body or the drain. This embodiment offers the advantage that the backflow loop for the higher safety aspect is incorporated into the shaft so that no installation work is required in the ground or in the building here.

In this case, if necessary with regard to regulatory requirements, 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).

In a further expedient embodiment, 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.

In a further expedient embodiment, 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.

For safety reasons, and also to additionally prevent the pushing back of channel gases or infestation of vermin, a second seat and a second flap may be provided in the downward slope upstream of the pump. This flap can swing freely or, optionally, also motor or manually or mechanically brought into the closed position or open position and held in this.

Finally, another important aspect of the backflow closure is that there is integrated a floor drain, expediently in a closure lid of the attachment piece. The floor drain collects surface water and directs it via the snorkel into the downgrade upstream of the shut-off element, from where it is disposed of either by gravity or by the pump. In the case of a backwater situation or a flood can thus penetrating into the building wastewater, for example, by a leaky window or a staircase into the basement incoming Wastewater, are disposed of immediately via the pump, so that water damage is kept within limits.

In summary, a user or installer with the backwater stopper according to the invention is given a universally different requirements in a substantially unmodified basic equipment fulfilling product that is operable not only with minimal energy consumption because of maintaining gravity disposal, even when operating with wastewater lifting function, but also different User requirements can optionally meet.

A backflow valve R in the Fig. 1 and 2 for sewage, in particular faecal wastewater, from a building is operable with a sewage lifting function H, However, if there is a backwater situation, there is the possibility of gravity disposal directly into the sewer K, as long as there is no backwater situation (or a user has not intentionally brought the backwater trap into a closed position).

The backflow valve R in the Fig. 1 and 2 has a base body 1 in the manner of a cleaning tube or inspection tube, which defines at least one inlet 2 and a drain 3, for example in coaxial arrangement, and between them a channel-like slope 6. Inlet and outlet 2, 3 are spigot pipe socket same, relatively large-ßer diameter at which 4 adapter pipe sections 5 can be attached via locking devices, for example, accordingly DE 37 08 552 C2 the applicant.

The downward slope 6 is covered by an intermediate part 8, here with the shape of a round pot, upwards. In the intermediate part 8, at least one pump 9 is removably mounted, the suction side 10 is located above in the downward slope 6, and the pressure or delivery side 11 is placed in the interior of the intermediate part 8. The base body 1 further includes an upper part 17, which sits on the intermediate part 8 and defines, for example, a sealing plane 18 in the form of a flange for floor installation and an insertion collar 19 for a top piece 20, which is closed by a cover 21 and installed in the ground level, when the backflow stopper R in, for example, a basement sole ( Fig. 5 ) is installed. In the embodiment in FIG Fig. 1 is in the cap 21 a bottom drain 22 incorporated, which is connected via a snorkel 23 with the slope line 6 (laterally past the pump 9). The floor drain 22 is an equipment option of the backwater stopper which is in Fig. 2 For example, in its basic configuration is shown.

The backflow lock R has at least one backflow loop connection 13, which in the embodiment shown is placed in a side wall 31 of the upper part 17 and is connected or connectable to the delivery side 11 of the pump 9 via a discharge connection 12. As a result, the backflow preventer R can be operated with the sewage lifting function H, for example, in which a pipe bend 14 is connected to the backflow loop connection 13 to a backflow loop 15 which, for example, via the backflow level 16 upwards and then to the sewage system K or a pipe 7 for Sewer K can be connected. The backflow loop port 13 may be placed at any suitable location in or at the backwater stopcock R.

In the downgrade 6 or in the base body 1, a seat 24 is formed for a shut-off A, which is designed here as a flap 25, which is relative to the seat 24 oscillating between the in Fig. 1 shown open position and in Fig. 2 shown closed position is movable. The return loop connection 13 is structurally separate from the downslope 6 and the shut-off element A. The flap 25 can, optionally, be moved by a flap actuator 26 manually and / or mechanically and / or motor. With the device 26 it is possible, the flap 25 in the in Fig. 1 to bring shown and hold open position, or in the in Fig. 2 bring and hold shown closed position, wherein an actuating arm 33 ( Fig. 2 ) of the device 26 on a corresponding control cam 34 (FIG. Fig. 2 ) or a cam 40 ( Fig. 4 ) can be brought to attack by a rotary movement of a hand lever 32.

The intermediate part 8 forms an in Fig. 1 indicated cover wall 28 for the downward slope 6, wherein, preferably, in this cover wall 28 downstream of the shut-off A in the Fig. 1 and 2 closed connection 27 may be provided to the slope 6. The pump 9 is removably mounted in the intermediate part 8 with a quick-release fastener 29, for example a clamping yoke closure. As an additional option, a slot 51 is formed in the downward slope 6 and in the base body 1, in which a in the Fig. 1 to 4 not shown insert with another seat and a further flap can be mounted, which then functionally function upstream of the pump 9 as Rückstausperre can (see Fig. 6 ).

The in Fig. 1 For example, shown pressure port 12 may be integrally formed with the housing of the pump 9 and extend to the backstroke port 13, or is, as shown, removable and / or interchangeable over in Fig. 4 shown quick release (clamping bracket 39, 40) between the pump delivery side 11 and the return loop port 13 mounted. On the delivery side 11 or in the backflow loop connection 13, a check valve 38 (FIG. Fig. 4 ), which automatically opens when the pump 9 is activated, but otherwise is in the blocking position.

Fig. 2 illustrates the backwater valve R in a basic configuration, in which the base body 1 includes the intermediate part 8 and the upper part 17, but no attachment piece 20 is provided with or without floor drain 2. In Fig. 2 is an operation with the wastewater lifting function H of the backwater stopper R possible because the delivery side 11 of the pump 9 via the discharge port 12 connected to the return loop port 13 is. In Fig. 2 is the flap 25 in the closed position on the seat 24, since for example the hand lever 32 is folded so that the arm 33 holds the flap 25 in the closed position via the cam surface 34. In a backwater situation, indicated by an arrow 35, no sewage can penetrate back into the building. The closed position can also be deliberately set by a user, for example, before a long absence. Waste water in the building must be in the operating position of Fig. 2 be disposed of via the sewage lifting function H, because the normal gravity disposal is blocked on the downgrade 6. In Fig. 2 is connected to the Rückstauschleifen terminal 13, the elbow 14, which is optionally installed together with the backwater valve R in the ground, and then to be connected to the Rückstauschleife 15.

The in Fig. 1 and 2 As shown, the backflow stop R shown can be converted between the in Fig. 1 and 2 shown sewage lifting function H and one in Fig. 3 shown direct pumping function P in the downgrade 6 and the drain 3 downstream of the flap 25. For this purpose in Fig. 3 the backstop closure 13 is closed by a plug 36, and the discharge nozzle 12 is the Fig. 1 and 2 exchanged against a discharge port 37, which connects the delivery side 11 of the pump 9 with the exposed port 27 'in the lid 28, so that pumped by the pump 9 wastewater pumped bypassing the flap 25 via the outlet 3 directly into the sewer. Fig. 3 also illustrates a non-return valve 38 on the delivery side 11. The flap 25 is as in Fig. 2 shown blocked in the closed position, so that here the slope line 6 for the gravity disposal of wastewater from the building is not available, and for disposal always the pump 9 must be put into operation.

In an alternative not shown (similar Fig. 7 ) to the embodiment in FIGS Fig. 1 to 3 For example, a second redundancy pump may be provided in the event of pump failure at the pump 9.

Fig. 4 is an axial section of the embodiment of Fig. 1 of the backflow stopper R and shows the clamping bracket 39, 40, with which the discharge nozzle 12 is installed. In dash-dotted lines with 37, a further embodiment of the backwater valve R is indicated, in which the discharge nozzle 12 to the return loop connection 13 and at the same time in Fig. 3 shown pressure port 37 leads to the exposed port 27 'in the cover 28 (a kind of trouser pipe), wherein at the delivery side 11 of the pump 9 a Pumpweg-Umstellvorrichtung 39 with a manual and / or mechanical and / or motor Umstellbetätigung 39 'is provided. This may be, for example, a valve arrangement, a flap arrangement, a rotary valve, or a tap arrangement, which makes it possible to change the backflow between the two functions: sewage lifting function H and direct pumping function P, without having to make a conversion. In Fig. 4 the flap 25 is brought by means of the hand lever 32 (by hand or motor) in the open position and held on the cam 40 from the arm 33, so that along the downgrade 6 to the drain 3, the normal gravity waste accumulating wastewater, even from the floor drain 22, if provided, is possible at any time, that is, as long as no backwater situation occurs or a user does not bring the flap 25 in the closed position and locked in this. Regardless of whether the backflow stopper R is operated with the wastewater lifting function H or the direct pumping function P, a normal gravity disposal along the downward slope into the sewage system is possible at any time without switching on the pump 9.

Fig. 5 illustrates the integration of the backflow stopper, here with the AbwasserhebeFunktion H, in a wastewater disposal system S of a building G, for example, a basement room 41, in the basement floor or bottom 42 of the backflow preventer R is installed so that it is flush with its top substantially with the bottom 42 and the drain 3 is connected via the connecting pipe 7 with the sewer K. To supply 2 lead manifolds of sinks and toilets. The floor drain 2 receives surface water, which penetrates into the basement room 41, for example, by a leaking basement window 43 in the event of a flood (arrows 44). This wastewater is pumped out by the pump 9, controlled by a corresponding sensor SE, immediately via the backflow loop 15, which is also connected to the sewer K and above the backflow level 16 (for example, the level of the floor outside the building G) leads. A controller CU is connected, for example, to the sensor system SE (and optionally provided servomotors at 26), and has, for example, an input and / or display section (not shown) and / or an audible or optical or electronic warning device connected to another location.

Fig. 6 illustrates another embodiment of the backwater stopper R, which is installed here in a slot M. The main body 1 of the backwater stopper R is formed here as a shaft channel 45, in turn, with the downward slope 6 to the outlet 3, the (not shown) is connected to the sewer. The downslope 6, which communicates with at least one lateral collecting chamber 6 ', is different in this respect from the here Fig. 1 to 4 trained intermediate part 8 covered, in which in Fig. 6 at least one pump 9 and two flap actuators 26, 26 'are installed. The device 26 'may optionally be used to actuate a second flap 47 relative to a second seat 48. The second flap 47 and its seat 48 are suitably contained in an insert part, which in the in Fig. 1 indicated insertion guide 51 in the base body 1 can be used and is located upstream of the pump 9, while the other flap 25 are arranged with its seat 24 downstream of the pump 9. In Fig. 6 the right flap 25 is held in its open position, while the left flap 47 is optionally freely oscillating and in its closed position, just because no wastewater is running. The delivery side 11 of the pump 9 is connected via the discharge nozzle 12 with the here placed within the side wall of the base body 1 backflow loop connection 13, where there may be provided, for example, a manually operable shut-off valve 50. The shaft M with its, for example, approximately cylindrical shaft wall 46 extends over a certain height upwards and is connected via an attachment piece 49 with a shaft crown. The manhole M can be installed in the ground so that the manhole is in the ground, or can be placed in a building or outside a building. The backflow loop 15 extends upwardly within the manhole M, but not necessarily above the backwater level, but over a height given by the manhole depth to eliminate the risk of backpressure being pushed back. The backflow loop 15 leads here within the shaft M through the base body 1 and / or the intermediate part 8 '(nozzle 51) directly into the drain 3. As long as there is no backflow situation, or a user does not deliberately open the flap 25 and / or 47 in the closed position has brought gravity disposal on the downgrade 6 is possible at any time. Only in a backwater situation and / or if a user has deliberately brought the flap 25 in the closed position, the pump 9 must be switched on to dispose of wastewater.

In the embodiment of Fig. 7 that a detail variant too Fig. 6 is unlike Fig. 6 in the intermediate part 8 ', a second pump 9' provided redundantly to the pump 9, and are connected to the delivery sides 11 of the pumps 9, 9 'via two separate discharge nozzle 12 two parallel Rückstauschleifen 15, which unite, for example, above and within the shaft M in the Procedure 3 are performed. The main body 1 forms again the Schachtgerinne 45, on which the in Fig. 6 shown manhole M is placed, namely around the side wall 31 'of the main body 1. The respective backwater loop terminal 13 is thus placed within the side wall 31'. Both pressure port 12 may be assigned manually operable shut-off valves 50.

In the Fig. 6 Otherwise, the embodiment shown can be converted for a direct pumping function P analogous to Fig. 3 , in which the pressure port 12 is exchanged for the discharge port 37, or may be equipped with two discharge ports 12 and 37, between which via the pump path Umstellinrichtung 39 analogous to Fig. 4 optionally switchable.
