Embodiment Construction

[0037] The drain valve 1 shown in the figures is designed for combination with a sanitary water tank (not shown), especially a concealed water tank. Conventional drain valves for sanitary water tanks are located inside the tank and are accessible for maintenance or repair purposes through inspection ports provided above the toilet or urinal.

[0038] In contrast, the drain valve 1 according to the invention is designed such that, in the assembled state, it is arranged below the water tank and thus outside the water tank. Therefore, the drain valve 1 realizes the migration of the inspection opening above the toilet or urinal in the traditional concealed water tank to a position behind the toilet or urinal, so that the inspection opening is completely covered by the toilet or urinal.

[0039] The drain valve 1 has a closed valve housing (drain valve housing) 2 which is provided with an inlet 3 and an outlet 4 . The inlet 3 is delimited by a connecting piece 5 which is preferabl...

Abstract

The invention relates to a drain valve for sanitary water tanks, especially concealed water tanks, said drain valve has: a valve housing (2) with a drain opening (4), wherein the drain opening (4) passes through a valve seat ( 6) defined; and the valve body (7) sealingly placed on the valve seat (6) in the closed state of the drain valve, wherein the valve housing (2) has In the housing chamber (11) containing water. In order to be able to place the drain valve outside the cistern and to be able to access it for its maintenance and disassembly through an inspection opening that can be covered by the toilet or urinal, the invention proposes that the valve body (7) is provided with a secondary chamber (12), the containment volume of the auxiliary chamber for water is smaller in the open state of the drain valve (1) than in the closed state of the drain valve (1), wherein the auxiliary chamber (12) is made of flexible and / or The moving wall section defines, and wherein the secondary chamber (12) is associated with a secondary drain valve (16), which in a first state allows water to flow into the secondary chamber (12) and in a second state allows Water flows out from the auxiliary chamber (12).

Description

technical field [0001] The invention relates to a drain valve for a sanitary flush tank, in particular a concealed tank, comprising: a valve housing with a drain opening, wherein the drain opening is delimited by a valve seat; and sealingly sealed in the closed state of the drain valve A valve body placed on the valve seat, wherein the valve housing has a housing chamber for receiving water arranged upstream of the valve seat in the outflow direction. Background technique [0002] Cisterns for toilets or urinals are known in various embodiments. Conventional sanitary water tanks, in particular concealed water tanks, have a tank in which inspection openings are formed in the front wall or top side. Functions such as drain and fill valves are installed in the tank through inspection ports. The inspection opening is usually combined with an operating panel which has one or two movably mounted operating buttons for triggering the flushing. The inspection hatch enables access ...
