Mixing Valve Temperature Limiting Ring for Simpler Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing valves have a complicated structure with a rotation limiting member that is difficult to assemble and operate, requiring a stopping limiting member and a stopping member to control the rotation angle of the valve rod, which complicates the adjustment of water temperature.
Innovation Solution
A mixing valve design featuring a balance valve assembly, a valve adjusting assembly, a temperature limiting ring, and a valve rod, where the valve rod extends through a limiting opening to limit the rotation angle, allowing for simple adjustment of water temperature through a rotatable valve adjusting assembly and a gap between the valve body and assembly for water output, with a block on the valve rod to limit the maximum water temperature.

Engineering Contradiction Analysis
1Manufacturing precision
If a stopping limiting member and a stopping member are arranged to control the rotation angle of the valve rod, then the rotation angle can be adjusted and limited, but the structure becomes complicated and difficult to assemble
Solution Approach 1:
The patent combines the stopping limiting member and stopping member into a single integrated temperature limiting ring that directly limits the rotation angle of the valve rod. This merging of components simplifies the structure while maintaining the rotation angle control function, resolving the contradiction between control precision and structural complexity.
Solution Approach 2:
The patent extracts the rotation angle control function from the complex multi-component system and implements it through a single temperature limiting ring with a limiting opening. This extraction simplifies the overall structure while preserving the essential function of limiting valve rod rotation to control water temperature.
2Manufacturing precision
If a stopping limiting member and a stopping member are arranged to control the rotation angle, then the rotation angle can be limited, but the assembly and operation become difficult
Solution Approach 1:
By merging the stopping limiting member and stopping member into a single temperature limiting ring, the patent makes assembly easier while maintaining rotation angle limitation capability. The simplified single-component structure is more straightforward to assemble and operate compared to the multi-component original design.
3Temperature
If multiple components are arranged to control water temperature mixing ratio, then temperature control is achievable, but the device complexity increases
Solution Approach 1:
The patent merges multiple temperature control components into a unified valve adjusting assembly that integrates the temperature limiting ring, valve rod, and mixing ratio control in a single assembly. This reduces device complexity while maintaining effective water temperature control capability.
Solution Approach 2:
The valve adjusting assembly is designed to perform multiple functions simultaneously: controlling the mixing ratio of hot and cold water, limiting the maximum water temperature through the temperature limiting ring, and enabling easy adjustment of water temperature. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.

AI summary
A mixing valve includes a balance assembly, and the balance valve assembly includes a hot water outlet and a cold water outlet. A plate assembly includes a first water limiting hole and a second water limiting hole, the valve adjusting assembly is rotatable with respect to the balance valve assembly to adjust an amount of fluid communicating between the water limiting hole and the water outlet to adjust a water temperature. A valve rod is connected to the valve adjusting assembly to drive the valve adjusting assembly to rotate. A temperature limiting ring defines a limiting opening, the valve rod extends through the limiting opening; the valve rod is arranged with a block; the limiting opening limits a rotation angle of the block. A valve body sleeves an outside of the valve adjusting assembly, a gap is defined between the valve body and the valve adjusting assembly.
