Disc Valve Radial Projection Rotation Stop Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc valves require precise initial positioning and subsequent testing of the control shaft to ensure the desired media flow, which is time-consuming and costly.
Innovation Solution
The disc valve incorporates a radial projection on the valve disc or control shaft, along with a rotation stop in the housing, to establish a mechanically defined initial position, eliminating the need for subsequent testing by ensuring a known angle of rotation and secure sealing without complex sealing points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If precise initial positioning and subsequent testing of the control shaft are performed, then the desired media flow is ensured, but the assembly time and production costs increase
Solution Approach 1:
The patent applies preliminary action by pre-defining the initial position of the control shaft through a mechanically constrained assembly structure. The control shaft is designed with features that automatically position it in the correct initial orientation during assembly, eliminating the need for subsequent testing and adjustment. This pre-establishment of the correct position resolves the contradiction by ensuring precision without requiring time-consuming post-assembly verification.
Solution Approach 2:
The patent implements self-service through a self-aligning assembly mechanism where the control shaft and valve disc automatically assume their correct relative positions during assembly. The design includes features such as keyed connections or geometric constraints that cause the components to self-position without external intervention or testing, thereby ensuring manufacturing precision while minimizing assembly time.

3Stability of the object's composition
If the valve disc and control shaft are connected torque-proof, then the relative position is maintained, but the assembly complexity increases
Solution Approach 1:
The patent applies asymmetry by incorporating asymmetric positioning features such as keyed connections or non-circular engagement elements between the control shaft and valve disc. These asymmetric features provide torque-proof connection and maintain precise relative positioning while guiding the assembly process, thereby reducing assembly complexity despite the requirement for stable relative position.

AI summary
A disc valve, in particular a multi-way control valve, is provided which has a housing that has an inlet connection and an outlet connection as connections for a liquid and/or gaseous medium. The connections end in respectively different chambers of the housing, at least one valve disc, in particular a ceramic valve disc, which is provided with at least one first through-flow opening and is arranged rotatably mounted in the housing in order to fluidically connect and separate from each other the different chambers depending on its rotational position by means of the through-flow opening, and a control shaft, which is connected torque-proof to the valve disc in the housing. The disc valve is characterized in that the control shaft or the valve disc has a radial projection, and the housing has at least one rotation stop, which is located in the movement path of the radial projection.
