Regulation valve

摘要

Regulation valve (10) for a liquid medium like water, especially for drinking water, comprising: a valve housing (11) providing a valve inlet chamber (12) and a valve outlet chamber (13); a valve insert being positioned within said valve housing (11), said valve insert comprising a valve body (18), a valve plunger (19) and a first spring element (20) being positioned between the valve body (18) and the valve plunger (19), whereby said valve body (18) provides a valve seat (21) for said valve plunger (19) and whereby said first spring element (20) provides a first spring force which tends to lift up said valve plunger (19) from said valve seat (21); a thermo element (22) being positioned directly in the flow of the liquid medium and carrying said valve plunger (19), said thermo element (22) provides a thermo element force acting on the valve plunger (19) depending on the temperature of the liquid medium within the valve housing (11), whereby said thermo element force provided by said thermo element (22) is acting against the first spring force provided by said first spring element and thereby tends to press said valve plunger (19) against said valve seat (21); a mounting support (14) for said thermo element (22), said mounting support (14) dividing the valve inlet chamber (12) of the valve housing (11) in a first valve inlet sub-chamber (12a) and a second valve inlet sub-chamber (12b), whereby the second valve inlet sub-chamber (12b) in positioned between the first valve inlet sub-chamber (12a) and the valve outlet chamber (13); a second spring element (25) being positioned in the first valve inlet sub-chamber (12a) and acting on the mounting support (14) in such a way that the second spring element (25) provides a second spring force which presses the mounting support (14) against a stroke (26) provided by the housing (11).
