Siphon for sewage or the like i liquids. "L ·.

In the case of sewage siphons with two centrifugal pumps, each pump must be in the two pressure lines each have a backflow flap, so off fluid cannot escape from the common pressure line *

If one arranges a separation, especially with small flow rates, that the centrifugal pump only receives roughly pre-cleaned material to be conveyed these do not clog, although the coarse additions of rubbish without to flow through the centrifugal pump, can not clog - have to but the varied wastewater the pump to the collecting tank flow through, whereby the Purapen impeller offers resistance and the Throughput is throttled. , "Sinking chamber Sine improvement, however, that in the pressure pipe between / SlfiftSSaSSä and Centrifugal pump a chamber was arranged, amplifies the inflow of liquid, because an opening flap creates an outlet in the collecting space.

If two pumps are arranged with backflow flaps, operation is not possible because the backflow flaps are under pressure Do not depressurise the settling chamber and keep the inlet flap as well as the flap between the pump and the collecting chamber closed.

This inconvenience with the arrangement of two pumps is now because of it that helped between the. two pressure ports, the named Pum = pen a ^ lamp housing is inserted and that the flap housing has a pendulum flap inside and in its end positions either the right or left not in operation circle = sel pump shut off at the seats that continue to operate both Pum = pen the pendulum flap reaches a vertical central position and that as a result, the sink chamber is depressurized via the pendulum flap and the overflow flap opens with every interruption of operation Wastewater α, like via the inlet flap in. Immediately to the collecting space Drain reaches. Further training consists in the fact that the Pendulum flap instead of dej? two sealing washers also by a hai = bated sealing ball can be replaced.

The subject of the invention is illustrated in an exemplary embodiment in the illustration.

The mode of action is as follows:

Wastewater or the like arrives from the inlet line 1. in antechamber 2 and open inlet flap 15 in. settling chamber 5 further through separating insert 6, open flap 22, pendulum flap 2?; 32 centrifugal pumps 757 ¹ UHd suction elbow 2g ^ 29 ", pump sumps 28j28 '" into the collecting space 13, Ms in In a known manner, the automatic activation of a centrifugal pump takes place. The pendulum flap 32 closes the pressure side of the centrifugal pump 7 ″ or 7fjuntil it is switched off again. If both centrifugal pumps are in operation, the pendulum flap 32 goes to its middle position _t tro "at _y from one or two centrifugal pumps in operation. Inlet flap 15 ß && ti is closed and pressure flap 17 is open. Entrance to the collecting space 13. The pendulum flap 32 can also have a hailed sealing ball instead of the sealing disks.
