Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-way globe valves in hydraulics are structurally complex, expensive, and lack high accuracy in mixing modulation, with suboptimal control of the second fluid's flow rate.
Innovation Solution
A three-way valve with a cruciform valve body and internal control/blocking means that can be switched between configurations to optimize the flow rate and pressure of the first fluid, optionally mixing it with a second fluid, while being constructively simple and easily modulated.

Engineering Contradiction Analysis
1Ease of operation
If a three-way globe valve is used to regulate fluid flow and mixing, then the flow rate can be controlled, but the structural complexity increases and manufacturing cost rises
Solution Approach 1:
The valve is divided into two independent control mechanisms: a first flow control element for regulating the first fluid and a second flow control element for regulating the second fluid. Each control element operates independently within the same valve body, allowing simplified control of complex multi-fluid flow regulation without requiring a complex single mechanism
Solution Approach 2:
The valve body serves multiple functions simultaneously: it houses both flow control elements, provides mixing chamber functionality, enables independent regulation of two different fluids, and maintains pressure control. This multi-functionality reduces the need for separate components that would increase structural complexity
2Ease of operation
If a three-way globe valve is used for fluid mixing, then flow regulation is possible, but manufacturing cost increases
Solution Approach 1:
By segmenting the control functions into two separate but integrated control elements, the valve can be manufactured using standardized components and assembly processes. The modular design allows for easier manufacturing and assembly compared to a single complex regulating mechanism
Solution Approach 2:
Instead of using a single complex globe valve mechanism to regulate both fluids, the invention inverts the approach by using two simpler control elements that independently regulate each fluid stream. This inversion simplifies the manufacturing process while maintaining regulatory capability
3Ease of operation
If a three-way globe valve is used for fluid mixing, then flow control is achieved, but mixing modulation accuracy decreases
Solution Approach 1:
The segmentation of control functions into two independent control elements allows each element to be optimized for precise regulation of its respective fluid. This independent control enables accurate modulation of mixing ratios without the mechanical interferences that limit single-mechanism valves
Solution Approach 2:
The valve design incorporates feedback mechanisms where the position and flow characteristics of each control element can be monitored and adjusted to achieve precise mixing modulation. This feedback capability ensures high accuracy in controlling the proportion of mixed fluids
