Valve Head Separate Fluid Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing upper valve parts for sanitary fittings route all water through a filter module, including rinsing and service water, which strains the filter and reduces its service life, as they lack separate control mechanisms for different fluid flows.
Innovation Solution
The design of an upper valve part that allows separate control of two fluid streams in opposite directions by arranging connection channels in the control disk to alternate between inlet and outlet channels, enabling needs-based removal of rinsing and filter water without mixing, with latching means for defined rotational positions and specific channel configurations for efficient fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all water is routed through a filter module, then water quality is improved, but the filter module experiences excessive strain and service life is reduced
Solution Approach 1:
The valve part divides the single water flow into two separate controllable streams: one for filtered water and one for rinsing water. The control disk with differentiated inlet/outlet channels segments the fluid paths, allowing selective routing so that only necessary water passes through the filter module, reducing its strain and extending service life.
2Adaptability or versatility
If a single control mechanism is used for all water outlets, then device complexity is reduced, but separate control of different fluid streams is not achieved
Solution Approach 1:
The control disk serves multiple functions within a single component: it acts as both a control element and a flow distribution element. By incorporating differentiated inlet and outlet channels in the control disk itself, the design achieves separate control of multiple fluid streams without requiring additional separate valve mechanisms, thus maintaining relatively simple device structure while providing versatile control.
3Ease of operation
If connection channels are arranged to allow simultaneous access to multiple outlets, then ease of operation is improved, but mixing of different fluid flows occurs
Solution Approach 1:
Different regions of the control disk are assigned different functions: certain areas contain inlet channels for filtered water while other areas contain inlet channels for rinsing water. The outlet channels are similarly differentiated. This local differentiation ensures that when one outlet is accessed, only the corresponding fluid stream is delivered, maintaining strict separation of fluid flows while allowing convenient access to multiple outlets.

AI summary
The invention relates to a valve head for the simultaneous control of two separate fluid flows for sanitary fittings, comprising a head that accommodates a base having two inlet channels and at least one first outlet channel, and a disc control with a control disc which is displaceable relative to a rotationally fixed flow disc via a rotatably mounted spindle, wherein a second outlet channel is arranged. Connecting channels (31, 32) are arranged in the control disc (3, 3') such that, in two different rotational positions of the control disc (3) relative to the flow disc (4), either a first inlet channel (51) and the first outlet channel (52) or the second inlet channel (53) with the second outlet channel (54) can be connected, with the other inlet channel (53, 51) and outlet channel (54, 52) being closed at the same time.
