Problems solved by technology

Due to the hydrostatic and hydrodynamic conditions, this type of drain fitting is disadvantageous because the valve body moves quickly from the flushing position to the closed position, and when the closing body hits the valve seat, a loud noise is generated

Embodiment Construction

[0057]In the drawings, a drain accessory 1 for the water tank is shown. The drain fitting 1 includes a valve body 2 having a sealing element 4 and a float 5, which is fitted with a valve seat. The valve body 2 can be moved from the seat 3 along the center axis M from the seat 3 to the flush position from the seat 3, and moves from the flushing position to the station. In the flushing position, water can flow through the gap between the valve seat 3 and the sealing element 4.

[0058]Further, the drain accessory 1 includes a float chamber 6. The float chamber 6 has an opening 28, and the valve body 2 extends through the opening. The valve body 2 is movably mounted in the opening 28. The float 5 moves substantially within the floating chamber 6 here, and hydraulically cooperates with the float chamber 6.

[0059]The float chamber 6 is configured such that it is completely enclosed by the side wall 34 until the end wall 19 except for at least one control channel 7. The control channel 7 pass...

Abstract

The invention relates to a drain fitting (1) for flushing tanks, comprising: a valve body (2) with a sealing element (4) cooperating with a valve seat (3) and a float (5), wherein the valve body (2 ) together with the sealing element (4) can move from the valve seat (3) along the central axis (M) from the rest position to the flushing position, and from the flushing position to the rest position; and the float chamber (6) with the opening (28) ), through which the valve body (2) extends, wherein the float (5) can move along the central axis (M) in the float chamber (6) and hydraulically cooperate with the float chamber (6). The float chamber (6) comprises at least one control channel (7), once the flushing water level (S) around the drain fitting (1) has dropped to the level of the control channel (7), from the outer area (8) of the float chamber (6) Air can enter the float chamber (6) through this passage, so that the pressure ratio between the float chamber (6) and the outer area (8) of the float chamber (6) can be balanced, wherein, when the pressure ratio is balanced, the float (5 ) can be moved from the flush position to the rest position. The float chamber (6) has a base (9) extending completely around the central axis (M) and a snorkel portion (10) adjoining the base (9). Preferably, viewed transversely to the central axis (M), the cross-section of the snorkel portion (10) is smaller than the cross-section of the base portion (9), wherein the cylindrical portion (11) of the float (5) extends into the snorkel portion (10) .

Description

Technical field[0001]The present invention relates to a drain accessory.Background technique[0002]From the prior art, it is known to trigger drain accessories from the water tank flush. In particular, it is known to selectively trigger a drain accessories for complete flushing or partially rinsing.[0003]For example, EP 0722020 shows this type of flushing device. For partial flushing, a weight that is selectively coupled to the valve body is arranged.[0004]Another drain fitting is known according to DE 10 2007 001 718, which has an extension adjacent to the float chamber. Due to fluid static and fluid dynamics conditions, this drainage fitting is unfavorable because the moving speed of the valve body from the flushing position to the closed position is very fast, and when the body hits the valve seat, a large noise is generated.Inventive content[0005]According to this prior art, it is an object of the present invention to define a drain accessory capable of overcoming the existing te...
