Drain valve for wash basins or the like

The innovation relates to a drain valve for wash basins or the like with a valve stem that can be inserted into the drain opening, which essentially consists of an overflow nozzle with an upper There is a collar and a screw connection piece with a support ring. Heretofore, these parts have been known as brass castings or manufactured as hot-pressed parts. The innovation is based on the fact that parts designed and manufactured in this way had the disadvantage of a relatively high cost of materials and a high weight, and difficult to polish was. In the case of castings, the inevitable rejects were also a disadvantage.

The innovation has set itself the task of eliminating these disadvantages and a drain valve of the fairy type create, which with low material expenditure a low Has weight, does not require any rejects, is easy to polish and has no solder or glue points.

This object is achieved according to the innovation essentially in that as an overflow nozzle and connecting piece of such a drain valve from the collar and support ring separate workpieces and automatic turned parts "are formed. In detail, according to the innovation of the Kraben at the Überleufstutzen and the support ring on the connector. by ring shoulders supported and advantageous, also as automatic turned parts be trained.

Further advantageous details of the innovation can be seen from the drawing, in which the innovation, for example is explained.

It shows:

Fig. 1 shows a drain valve according to the innovation in longitudinal section, and

Fig. 2 and 3 the overflow nozzle and collar

once separated (Fig. 2) and assembled (Fig. 3).

In the illustrated embodiment, the valve plug is denoted by V. The one in the indicated wash basin floor The adjustable vent shaft consists of the collar 1, the overflow nozzle 2 and the connection nozzle 3 with support ring 6th

According to the innovation, each overflow nozzle 2 and collar 1 and connecting piece 3 with support ring 6 than from each other separate workpieces and trained as automatic turned parts! det. The collar 1 is supported by one from the drawing

• Obvious ring projection 20 against a shoulder shoulder 21 of the overflow nozzle 2, while the support ring 6

• is supported on a shoulder 7 of the connecting piece 3.

As can be seen from Fig. 2 and 3, the collar 1 in the Kontage simply pushed onto the overflow nozzle 2 from below and both parts seal each other without Solder or glue connection.

JJie in Fig. 3 marked with ^ rectangular sections are ir. Such drain valves usual overflow opening. \ urz: ve. c :. ~ ζ "· .: Knowing what to do if the Wasct -e: - :.:,.;:. · :: ·; Ί. ': ι: ■:': -..-.- slots drains into the drain

entry.

Nozzle 5 is attached to the socket when it is installed on the wash basin 2 screwed on. The drain valve is sealed against the underside of the sink using a rubber ring 5i which by a support ring 6 from the shoulder 7 of the connector 3 is pressed against the lower edge of the wash basin opening 8.

A ball rod 9 is in the usual Ueise by a pull button or moved up and down from the top of the washbasin by an eccentric lever in order to move the valve cone V to open or close.

The ball rod 9 is guided in a plastic sleeve 10. This plastic sleeve 10 has an external thread Shank 11 and a rectangular head 12. In the rectangular head 12 is a slot-shaped guide 13 for the Ball rod 9 is provided.

The slot-shaped guide 13 is narrower in the middle than above and below. This ensures that the ball rod

9 clearly engages in its end positions "open" or "closed" and thereby opens the valve plug with certainty or keeps closed, which is not always the case with conventional constructions.

The resilience of the plastic material in the narrower central area of the guide 13 is supported by recesses 14 and 15.

When assembling the drain valve, the plastic sleeve

10 from the inside of the nozzle 3 through a hole in the

The wall of the connecting piece is inserted through it and then from the outside by screwing the sleeve 16 onto the threaded shaft 11 attached.

The O-ring 17 seals the ball of the ball rod 9 against about escaping water. A nipple 18 screwed into the internal thread of 16 presses the ball of the ball rod 9 against the O-ring 17, which in turn is held on the end face 19 of the plastic sleeve IO.

All technical details explained in the description and illustrated in the drawing are for the novelty of importance.
