DRAINAGE DEVICE IN ASSEMBLY, DRAIN DEVICE HOUSING FOR USE IN SUCH DEVICE IN ASSEMBLY AND SEWER SIPHON FOR USE IN SUCH DEVICE IN ASSEMBLY Russian patent published in 2019 - IPC E03F5/04 

FIELD: water supply; sewerage.

SUBSTANCE: group of inventions relates to the field of drain devices. Sewage siphon (100) comprises a first drain channel located between inlet (110) and outlet (130), which comprises, if seen in direction of flow, first closing wall (115) for covering uppermost part of drain channel and second closing wall (125) located at certain distance from first closing wall and intended for covering the lowest part of first drain channel. First and second closing walls overlap if seen in horizontal direction. Sewage siphon comprises an elongated main body. Inlet (110) essentially passes along the length of the first flat surface of the main body, which is set by the first closing wall (115). Second closing wall (125) is located in the main body. Outlet (130) is located on second flat surface (135) of main housing, located opposite first flat surface and at certain distance from second closing wall (125), due to which water will enter the main housing, flowing through barrier formed by second wall (125), in direction of outlet (130) on second flat surface (135), which forms external boundary of main housing. Drain device assembly comprises above described sewer siphon (100) and housing (200) drain device for installation in the floor, equipped with a recess for placement in it of the above sewer siphon (100). Said recess is configured so that outlet (130) or each of outlets (130) of sewer siphon (100) is connected to second drain channel (220) provided on drain device body. Drain device body (200) is shaped so that after its installation into the floor it is possible to easily extract sewage siphon (100) from the recess. Recess is connected to collector zone (210) located on inlet (110) side. Manifold area (210) is located at least partially under floor, which is laid after installation of drain device housing into it.

EFFECT: provides for compactness of siphon with high flow rate, availability and possibility of removal for effective cleaning and maintenance.
