Description

761 61

The present invention relates to a drain with an inlet part with support surfaces for a screen and / or a compression ring and a dam wall arranged between the water trap tongue and an outlet pipe projecting laterally from the inlet part, the water tongue having a part above the dam wall.

In recent years, it has been possible to significantly reduce the overall height of sewers of the type indicated in the introduction, but the structural changes carried out have often resulted in a large reduction in the flow capacity of the well. In other cases, strength and / or manufacturing problems have also arisen.

The object of the present invention has been to eliminate these problems, i.e. in a Mata-15 structural sewer of the type described in the introduction, by simple means to provide a well which obtains good flow capacity and also becomes stable and easy to manufacture, for example from plastic. This is achieved mainly by the fact that the manhole shown in the introduction has acquired the characteristics which appear from the following claim 1.

The invention will be explained in more detail below with reference to the accompanying drawings, in which Figure 1 shows a longitudinal section of a sewer according to the invention, Figure 25 2 shows a cross-section of a well without an installed insert and Figure 3 shows a floor view without said insert.

The floor drain shown in the drawings is made of a plastic material and mainly comprises an inlet 30 part 1 and an outlet pipe 2 projecting laterally from the inlet part. The inlet part is fitted with an insert 3 which forms a water trap tongue 4 when placed in the inlet part 1. A dam wall 5, 35 is further arranged in the inlet part 1 between the water trap tongue 4 and the outlet pipe 2, which together with the water trap tongue 4 forms a water trap in the well, in which water collects up to the level 6.

In order to facilitate the flow of water from the inlet part 1 to the outlet pipe 2, the dam wall is formed or has an outlet part 2 76161 which extends obliquely downwards towards the outlet pipe 2. In addition, the length of the outflow section 7 is half the width of the sections of the inlet section 1. In addition to the preferred flow, this obliquely downwardly directed outflow part 7 facilitates the manufacture of the well so that the mold part belonging to the casting equipment can be pulled obliquely upwards from the inlet part 1, in addition to which the outlet part 7 assists in reinforcing the well inlet part 1.

The flow-through capacity can be improved so that the dam-10 in the wall 5 has a dam section 9 running into the inlet part 1 upwards from the bottom part 8 towards the outlet pipe 2, which at the top turns into an outflow part 7.

The outflow part 7 preferably turns into a substantially vertical part 10 at the bottom, which at the bottom opens into the lower wall parts 11 of the outlet pipe 2 to form a sewage barrier intended to prevent water flow or in any case effectively counteract the flow of water -20 in the formation of tea, but part 10 can in certain cases substantially improve the inhibitory effect.

The flow from the inlet well is facilitated in a particularly large amount if the outflow section 7 extends from a plane at the height of the upper wall parts of the outlet pipe 2 to a level which is at the height of the center 13 of the outlet pipe 2. In addition, the inlet part of the well shown has side wall parts 14 and 15 which extend from the outflow part 7 towards the outlet pipe 2 and terminate completely or partially downwards / inwards towards the center 13 of the outlet pipe 2. The side wall portions 14, 15 extend suitably some distance into the outlet pipe 2 and preferably end in a wall portion 16 substantially parallel to the outflow portion 7.

In order to further ensure that the well has a favorable flow capacity and thus a good "swallowing capacity", regardless of the low overall height, the part of the water trap 4 above the outlet part 7 and in particular above its highest point 17 on its underside 19 3 761 61 runs in a plane in or above the plane of the strainer and / or clamp ring seat 20 of Part 1. Despite this increase, in order to ensure that the downstream background to the inlet part 1 is not impeded, the insert 3 forming the water trap tongue has a downstream edge 21 which is lower than the part 18.

The invention is not limited to the embodiment described above and shown in the drawings, but may vary within the scope of the following claims. Thus, at the level of the inlet part 1, the parts 22 immediately above the outflow part 7 may have an outwardly directed flange 23, the upper side and the lower side 25 of which form an acute angle with each other. In this case, the underside of the flange 23 may be horizontally oriented to burn the well to the horizontal position on the substrate 25, while the upper side 2k may extend downwards / inwards to facilitate downflow into the inlet part 1. The inlet parts 1 are intended for floor covering 26. not shown) and a sieve member (not shown) of a known type. The insert 3 preferably has a groove 27 for the sealing ring 28 and for snaping the flanges into the inlet part. 1. The invention is, of course, applicable to floor drains or other sewers 25 made of a material other than plastic and to a water-locking tongue belonging to an insert which can be installed instead of a fixed water-locking tongue.
