Problems solved by technology

This however has a negative effect on the sewage discharge capacity or the volume flow of the branch pipes, which leads to the need for larger diameter branch pipes in order to obtain a comparable sewage discharge capacity
This is again undesirable since a larger installation space would be required

Embodiment Construction

[0028] figure 1 and figure 2 A branch fitting 1 for application in a sewage downpipe of a multi-storey building is shown. Branch fittings 1 are used to connect the sewage supply pipes from a floor into a downpipe which extends from floor to floor, usually over the entire height of the building. The supply pipe is thus connected to the downpipe via the branch piece 1 .

[0029] The branch piece 1 comprises: an upper downpipe part 2 with an inflow opening 3; a deflection part 4 adjoining the upper downpipe part 2; a lower downpipe part 5 adjoining the deflection part 4 and having an outflow opening 6; and at least one feed pipe section 7 through which additional sewage is introduced into the downpipe. The upper downpipe part 2 , the deflection part 4 and the lower downpipe part 5 are surrounded by a wall 11 , 20 . The upper downpipe part 2 of the branch piece 1 is connected to an upper downpipe (not shown) and the lower downpipe part 5 is connected to a lower downpipe (also...

Abstract

A pipe branch piece (1) for a downpipe in which sewage in the form of a sewage layer can be guided on a wall in a fall direction (F) comprises an upper downpipe section, a diverting section, and a lower downpipe section, as well as at least one supply pipe section, wherein the diverting section comprises at least one diverting region (8) and a flow region (12) having a wall (11). The diverting region (8) comprises a diverting surface (10), running along a flow curve or flow line (M) and of curved configuration, for the bundling of the sewage as a jet (S), which flow curve or flow line (M) runs at a first angle (Belta) with respect to the fall direction (F) and at a second angle (Alfa) with respect to a plane (E) extending through the fall direction (F), wherein, as a result of the two angles (Belta,Alfa), the curved diverting surface, with its flow curve or flow line (M), is directed substantially tangentially to the wall (11) of the flow region (12).

Description

technical field [0001] The invention relates to a branch piece for a downpipe according to the preamble of claim 1 . Background technique [0002] Such branch pieces are known from the prior art. For example CH 418067 discloses such a pipe branch. [0003] The applicant also presents on the market a pipe branch under the name Geberit Sovent which, in the form of fittings, offers a cost-effective and technically advanced solution for the drainage of sewage into multi-storey buildings, especially high-rise buildings. into the sewage downspout. [0004] The product Geberit Sovent and branch fittings according to CH 418067 give very good results. Since then, however, the requirements regarding the drainage capacity, the drop height and the dimensions of such branch pieces have increased day by day. [0005] In particular, negative pressure in the supply line should be avoided as far as possible during operation. This negative pressure is generated by the sewage flowing into...
