Embodiment Construction
[0034] figure 1 An embodiment of the valve is shown with a valve housing 2 defining an inlet opening 4 and an outlet opening 6 . A spacer 8 is provided in the valve housing 2, which spacer defines a bore in which the valve insert 10 is sealingly mounted.
[0035] The valve insert 10 has a valve insert housing 12 in which a spindle 14 is rotatably supported, the spindle 14 being supported by an adjustment top 16 that is screw-fastened to the valve insert housing 12 . The adjustment top 16 has a protrusion that engages over a portion of the main shaft 14 to axially hold the main shaft 14 in place relative to the valve top 16 . The valve top 16 is screwed securely inside the valve insert housing 12 and can be adjusted there, allowing the spindle 14 to be preset.
[0036] The main shaft 14 is a non-rising main shaft which engages with a setting element 18 which, on the opposite side, cooperates with a valve disc 20 which engages the opening of the setting element 18 by means of...

The invention relates to a valve for drinking water installations, comprising: a valve housing connected to a pipeline; and a regulating piston movable in the valve housing and coupled to a main shaft exposed on the outside of the valve housing, and cooperate on the side opposite to the main shaft with a thermal expansion element which is exposed in the flow path through the valve housing and which rests against the adjustment piston under the preload of the spring element, due to the expansion of the expansion element, the adjustment piston Can move relative to the bore. In the above-mentioned valve, the adjusting piston limits the Kv minimum setting area, and at the Kv minimum position of the adjusting piston, a Kv minimum flow path is formed between the adjusting piston and the bore; The support points on the surface and the flow passage hollow body in the middle define the Kvmax setting area, at the Kvmax position of the adjusting piston, the support points extend up to the bore and the flow passage hollow bodies arranged between the support points define the Kvmax flow road.
Description
technical field [0001] The present invention relates to a valve for drinking water installations. Such a valve is known from DE 10 2011 010 840 A1. Background technique [0002] The present invention particularly relates to valves for regulating the circulation of cold water. A flow path for drinking water is formed in the valve housing, in which flow path a thermal expansion element is exposed which rests against the regulating piston under the preload of the spring element. Due to the expansion of the expansion element, the adjustment piston moves relative to the bore. As a result, temperature-controlled regulation of the flow through the valve takes place. The purpose of this flow through the valve is to set a Kv minimum for the cold drinking water so that only minimal circulation will occur when the drinking water is sufficiently cold. On the other hand, if the temperature of the drinking water increases, the purpose of increasing the circulation through the valve is...
