Die-Cast Thermostatic Valve Body With Reinforcing Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing thermostatic valves face challenges in achieving lightweight designs due to limitations in profile machining, which results in excessive material usage and increased production costs.
Innovation Solution
The thermostatic valve is designed using die-casting technology, allowing for the integration of a main valve body, connecting tube portions, and a mounting base portion. This approach enables the removal of redundant materials, reduces weight, and saves production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If profile machining is used to manufacture the thermostatic valve, then the structural strength can be maintained, but the weight reduction and material saving are limited
Solution Approach 1:
The patent changes the manufacturing method from profile machining to die casting, fundamentally altering the production parameter. This enables complex three-dimensional structures to be formed directly during casting, achieving weight reduction by removing redundant materials while maintaining structural integrity through the die casting process capabilities.
Solution Approach 2:
The valve body is divided into functional regions (main body, mounting base, connecting tubes) that are integrated through die casting. This segmentation allows each region to be optimized independently for weight reduction while the die casting process integrates them into a unified structure, eliminating the need for separate machining operations on each component.
2Loss of substance
If die casting is used to form the valve body, then the weight can be reduced and material waste minimized, but the structural strength may be compromised
Solution Approach 1:
Reinforcing ribs are strategically positioned at critical stress zones within the die-casted valve body. This local quality enhancement ensures that strength is concentrated where needed most, compensating for the potentially reduced overall strength of die-casted components compared to machined parts, while maintaining material efficiency throughout the rest of the structure.
Solution Approach 2:
The valve body utilizes a composite structure combining the die-casted base material with integrated reinforcing ribs. This composite approach creates a heterogeneous internal structure where different regions have different material densities and properties, optimizing both weight reduction and structural strength simultaneously.
3Ease of manufacture
If die casting is employed to manufacture the valve body, then production costs can be reduced, but additional design considerations are required to ensure structural integrity
Solution Approach 1:
The design merges multiple functions into the die-casted valve body structure, including integrating the mounting base, connecting tubes, and reinforcing ribs as integral parts of the single casting. This merging eliminates the need for separate manufacturing and assembly operations, reducing production costs despite the increased complexity of the die casting mold design.

AI summary
A thermostatic valve comprises a valve body (100) formed by die casting. The valve body (100) comprises: a valve main body (500) forming a valve cavity; a plurality of connection tube portions (101, 102, 103, 104); and installation base portions (201, 202) adjacent to the connection tube portions. Each of the connection tube portions comprises a straight tube section (10a) connected to the valve main body (500). A reinforcement member (40R) is provided between the straight tube section (10a) of the connection tube portion and the installation base portion adjacent to the connection tube portion. The valve body is formed by die casting, and respective parts of the valve body can be processed according to actual size requirements with no redundant material, thereby realizing a light weight of the thermostatic valve. Providing the reinforcement member satisfies a strength requirement when using die casting.
