Definitions
- the invention relates to an odor trap of the type specified in the preamble of claim 1.
- a gully with an odor trap of this type is known (US-A-1 328103), in which an inlet funnel is formed in the upper part of a concrete body and an outlet space is formed in the lower part, which is tapered in the direction of flow and becomes one in the manner of a pipe elbow leads sewer connection line running downwards.
- the two rooms are separated from each other by a metal plate embedded in the concrete, which is provided with an opening that connects to the funnel exit.
- a piece of pipe is attached to the opening, which protrudes into the outlet space and is obliquely cut off at the bottom, its edge forming the seat for the flap.
- the outlet area is expanded next to the pipe section to accommodate the flap pivot axis and the counterweight.
- the invention seeks to remedy this.
- the object is achieved to provide an odor trap that is less prone to clogging and, if necessary, easily and effortlessly, for. B. with a cleaning rod, completely and can be cleaned well into the sewer connection line.
- Particular embodiments of this invention are specified in the dependent claims.
- a flap 1 and the associated seat 2 are arranged in the straight downward flow path A-B of the odor trap shown.
- the pivot axis 4 of the flap 1 (see. The pin 3 in Fig. 2) runs next to the seat 2 outside the flow path A-B.
- the seat 2 is inclined downwards with respect to the flap pivot axis 4, i. H. arranged in a plane running obliquely downward from the pivot axis 4 or parallel to such a plane, depending on the position which the pivot axis 4 has with respect to the flap plane.
- a counterweight 6 acts against the gravity of the flap 1, the center of mass of which, when the flap 1 is at rest, is approximately at the same height as its pivot axis 4.
- the flap 1, together with its pin 3 and its counterweight 5, can be made in one piece from metal.
- the housing of the odor trap which can be made of plastic or metal (sheet metal or cast iron), has a tubular housing main part 6, in which the rectilinear flow path AB runs, and a box-shaped housing attachment 7.
- the upper end 8 of the tubular part 6 is connected to the (not shown) to connect the lower end of a water drain pipe.
- the lower end 9 of the tubular part 6 is to be tightly connected to a sewer connection line (not shown), as is customary in the case of known odor traps.
- the flap 1 and the seat 2 are in the tubular part 6, the counterweight 5, the pin 3 and associated pin bearing 10 are arranged in the housing shoulder 7.
- a cross-sectional half of the tubular part 6 engages between the front and rear walls 11 and 12 of the housing extension 7 in FIG. 1.
- the jacket half 13 of the tubular part 6 running in the neck 7 has a recess which extends from the seat 2 to the bottom 14 of the neck 7 over half the circumference of the tube, so that the jacket half 13 is cut out below the seat 2 to the bottom 14.
- the upper edge of the recess is 15, the lower is 16.
- the upper wall 17 of the extension 7 is provided with an opening 18, the clear width of which is not significantly smaller than that of the tubular part 6 is.
- the opening is closed by a cover 20 which is detachably fastened by means of screws 19, a seal 21 effecting an airtight closure.
- the bearings 10 for the pins 3 of the flap 1 are U-shaped bearing shells arranged on the front and rear extension walls 11 and 12, from which the pins 3 can be lifted upwards. This enables the flap 1 with its counterweight 5 to be removed from the housing 6/7 with the cover 20 removed after it has been pivoted into the position shown in broken lines.
- the distance of the counterweight 5 from the wall 22 of the housing attachment 7 is dimensioned such that the counterweight 5 can be grasped in the closed position of the flap 1 in order to pivot the flap 1 with the counterweight 5 into the open position and to remove it.
- the counterweight 5 could also be provided with a suitable handle (not shown).
- a stop 23 limits the opening movement of the flap 1.
- the legs of the U-shaped bearing shells 10 can be resilient and have a distance at the top that is smaller than the diameter of the pins 3, so that they are lifted out only by overcoming the spring force, but are lifted out cannot undesirably detach from the bearing shells 10, for example if a larger water flow hits the flap 1 asymmetrically.
- the side wall of the housing extension 7 then runs obliquely downwards on the wall part 22 (wall part 24) to the bottom 14 of the housing extension 7 at the lower edge 16 of the recess.
- the inclined wall part 24 is at a distance from the pivot axis 4 of the flap 1 that is not significantly smaller than the inside width of the tubular part 6.
- the wall part 24 serves as a guide for a cleaning rod, which, if necessary, can be introduced for cleaning the lower part of the odor trap and the sewer connection line (not shown) connected to its lower end 9, after which the cover 20 is removed and the flap 1 with its counterweight 5 was removed.
- the pins 3 can be arranged on the housing shoulder 7 and the bearing shells 10 on the flap 1, the latter being in the flap rest position with the open U-side pointing downwards or obliquely downwards, and the distance of the pins 3 from the jacket half 13 of the tubular housing part 6 must be dimensioned so large that the bearing shells 10 can be pulled off the pin 3 in the position of the flap 1 shown in broken lines in FIG. 1.
- the seat 2 runs on the inside of the tubular housing main part 6.
- the clear cross section of the flow path AB in the region of the seat 2, viewed in the direction of flow, is somewhat smaller than above and below the seat 2.
- the circumferential half of the tubular main part 6 opposite the housing extension 7 is provided with a bulge, and the housing extension 7 is designed to be wider than the bulge, with one circumferential half of the seat in the bulge and the other circumferential half below the lower edge the jacket half of the tubular housing main part designated 13 in FIGS. 1 and 3 is arranged.
- the bulge is to be dimensioned below the seat so that the pivoting of the flap 1 is guaranteed. This makes it possible to use a seat whose clear opening, as seen in the flow direction A-B, matches or is even larger than the clear cross section of the tubular housing main part 6.
- the seat is to be arranged on its approximately half circumference opposite the housing extension 7 in the bulge and opposite this at the lower edge of the edge of the upper circumferential half designated 13 in FIGS. 1 and 2; it only projects on its parts lying opposite one another parallel to the flap pivot axis 4 into the flow path. .
