Drain valve base for a basin Description

The invention relates to a drain valve base for a basin, wherein the drain valve base can be inserted into a drain nozzle of the basin and ends at the base in a threaded section for a siphon housing or ring housing.

The invention is used in the basins of sanitary facilities, in particular washbasins, bidets and the like. A conventional drain valve housing made of metal is a complex turned part. This must be installed or cemented into the drain connection, which is a laborious process.

The object of the invention is to provide a drain valve base that is easy to manufacture, easy to assemble and universally applicable.

This object is achieved according to the invention in that the drain valve lower part is designed as a molded part, is completely immersed in the drain nozzle and is sealingly attached to the inner wall of the drain nozzle with a sealing ring.

The invention differs from the prior art in that the molded part can be adapted to any design. Installation with a seal is possible. There is no need for cementing. The position of the drain valve base inside the drain connection allows the valve cone to be submerged so that the bottom of the basin is free.

The drain can be covered by covering the valve cone that is immersed in the drain valve base with a cover.

A secure seal within the drain connection is possible because the sealing ring of the drain valve base engages with a sealing edge of the drain connection. In this way, a seal is achieved by tightening the drain valve base against the siphon housing.

In another way, the drain nozzle can be sealed by having a sealing ring of the drain valve base rest against a conical surface of the drain nozzle.

For sealing in a drain connection with a cylindrical inner wall, the sealing ring is designed as a tapered ring that rests against a conical surface of the drain valve base. This design allows installation in any drain connection.

For a pool with an overflow channel, the drain valve housing is provided with openings for an overflow channel below the sealing ring.

A self-centering seal of the valve cone is ensured by the fact that the head surface of the drain valve base is designed as a conical sealing surface for a valve cone.

DE 202 06 470 Ul describes a valve cone with an integrated overflow. The drain valve base can be adapted to this valve cone in that the drain valve base has a conical sealing surface on the inner wall, which is set lower than the head surface of the drain valve base.

Examples of embodiments are explained using the drawings, which show:

Fig. 1 a drain valve base for a basin with overflow, Fig. 2 a modified example,

Fig. 3 a drain valve base for a basin without overflow, Fig. 4 a modified embodiment and

Fig. 5 shows another embodiment of a drain valve lower part.

Fig. 1 shows a schematic of the drain of a washbasin, a bidet or a similar sanitary facility. In the base 1 of a washbasin there is a drain connection 2, to which an opening 3 of an overflow channel 4 is connected at the side. A sealing edge 5 is incorporated into the drain connection 2 above the opening 3. An essentially cylindrical drain valve lower part 6 is inserted into the drain connection 2 with a sealing ring 7 in between. The head area 8 of the drain valve lower part 6 is designed for the dimensions of the drain connection 2 and is immersed in the drain connection.

At the level of the mouth 3 of the overflow channel 4, openings 9 are provided through which overflow water can flow away. The drain valve lower part 6 ends in a threaded section 10 onto which an internal thread of a siphon housing or ring housing 11 can be screwed. A sealing ring 12 is located between the upper edge of the siphon housing 11 and the lower edge of the drain connection 2. The siphon housing 11 has an inlet opening 13 for a ball rod (not shown). The top of the drain valve lower part 6 is designed as a conical sealing surface 14.

The drain valve lower part 6 described is a molded part. This means that the drain valve lower part 6 can be adapted to any shape. Additional components are not required. Installation in the drain connection is carried out without additional components by clamping between the sealing surface of the drain connection and the ring housing. A seal or sealing compound is not required.

The drain is completed by a valve cone 15 and a cover 16. The valve cone 15, which is completely immersed in the drain connection, sits with a sealing ring 17 on the sealing surface 14 of the drain valve base. An adjusting screw 18 works together with the ball rod (not shown). The cover 16 covers the drain valve base, which is immersed in the drain connection, and engages with guides 19 in the drain connection 2. The cover is thus fixed and is not lifted by the movement of the valve cone.

In the embodiment according to Fig. 2, the inner wall of the drain nozzle 2 is designed as a conical surface 20, against which a conical surface 21 of the drain valve lower part 6 rests in a sealing manner with the interposition of a sealing ring 7.

The embodiment according to Fig. 3 is intended for a basin without an overflow. The overflow water is drained away by a valve cone (not shown) with an integrated overflow device. The drain valve lower part 6 has a conical sealing surface 23 in the area of the inner wall 22, which is set lower than the head surface of the drain valve lower part. This is a prerequisite for the use of a valve cone with an integrated overflow device.

The drain valve lower part according to Fig. 3 is sealed by the sealing ring 7 on a sealing edge 5 of the drain nozzle 2.

In the embodiment according to Fig. 4, a conical sealing surface 20 of the drain nozzle 2 is provided, on which the sealing of the drain valve lower part takes place.

The embodiment according to Fig. 5 can be used with a drain connection of any shape, even with a drain connection 2 with a cylindrical inner wall 24. The outer wall of the drain valve lower part 6 ends at the head end in a widening conical surface 25. A tapered ring 26 rests against this conical surface 25 and is held in place by an adhesive on the drain valve housing before assembly. When the ring housing 11 is tightened onto the threaded section 10, the tapered ring 26 is tightened in a sealing manner.
