Floor drain

The innovation concerns a floor drain for draining wet rooms or wet cells. Such drains are equipped with an odor trap in accordance with the Bor's regulations, the liquid barrier of which is formed by an upper flow and an engaging bell submerged in the liquid.

Recently, there has been a growing demand for the floor drain to be lockable. The suggestion has therefore been made to make the bell adjustable in height and to provide its underside with a sealing ring. The valve spindle is mounted in the inlet grate (DE-U 75 01 550). The bell must be guided to the standpipe firmly connected to the drain housing to prevent it from twisting.

In another known Atri design, the valve plate is located on the lower edge of the standpipe that protrudes into the drain connection.

The task of avoiding these disadvantages of the known designs and in particular of introducing a closable odor trap that can also be replaced later is solved according to an innovation in that the standpipe is detachably inserted into the bottom of the drain by means of a sealing ring, that the bell is detachably connected to the standpipe and that the valve plate is located on the underside of the bell and, when closed, sits on the upper edge of the standpipe. The valve plate is now located in a place where it does not impede the flow and therefore does not become dirty. The valve spindle is short and easy to reach. The bell can easily be removed from the standpipe to check the valve plate and the seal.

Construction details of the valve and odor trap can be found in the example of the innovation described below. In Fig. 1, the new floor drain can be seen in section in Fig. 1, the odor trap in plan view and in Fig. 3 a detail in view Z of Fig. 2 can be seen. The drain housing 1 has, as usual, a connection piece 2 for the drain pipe 3 at the bottom and a fixed flange 4 at the top for tightly clamping a tensioning strip 5. Above the tensioning strip 5 there is a soundproofing and impact sound insulation 6, which is covered by a second tensioning strip 8 connected to an upper part 7. The adaptation to the floor covering 9 is achieved by an attachment piece 11 covered by the inlet grate 10 and infinitely height-adjustable.

The odor trap 12 consists of a rolling

standpipe 14 inserted into the drain connection 2 with upper overflow edge 15 and the overlapping bell 16. Both are spaced apart and connected by radial ribs 17, the lower edge of which is also the stop for the installation position of the odor trap 12. The ribs 17 have bevels 18 at the top with which they are screwed to the bell 16 (Fig. 3). Vertical slots are provided in the edge of the bell for this purpose.

The bell is perforated at the top for a valve spindle 19, which is adjustable in a flanged nut 20. The valve plate 21 attached to the lower end of the spindle contains a sealing ring 22, with which the standpipe and thus the floor drain can be closed. This closure not only serves to retain undesirable liquids, but also to test the tightness of the connected pipe 3. The valve is operated using the handle 23. The handle is also the grip by which the entire odor trap can be pulled.
