Multi-Core Control Valve Assembly for Compact Flow Switching

Solution Overview

Problem

Existing fluid control systems with gear meshing mechanisms are complex and occupy significant space, making them difficult to manage and integrate multiple valve core flow passages effectively.

Innovation Solution

A control valve system featuring a valve body with multiple ports, a first and second valve core, and transmission parts that rotate synchronously with the valve core shaft, allowing for simple assembly and various flow passage switching modes by adjusting the angle of the valve cores within a preset range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If gear meshing mechanism is used to adjust rotation angles of multiple valve cores, then flow passage switching is achieved, but device complexity increases

Engineering Contradiction:

Improveflow passage switching capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve core is divided into multiple independent segments (first valve core segment, second valve core segment, third valve core segment) that can rotate independently relative to each other. Each segment controls different flow passages, eliminating the need for complex gear meshing mechanisms while achieving multiple flow passage switching configurations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple valve core segments are nested within the same valve cavity, with each segment capable of independent rotation. The first valve core segment, second valve core segment, and third valve core segment are arranged concentrically, allowing compact integration of multiple control functions within a single valve body without increasing overall device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If gear meshing mechanism is used to adjust rotation angles of multiple valve cores, then flow passage switching is achieved, but system space occupied increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

Multiple valve core segments are nested within the same valve cavity, with each segment capable of independent rotation. The first valve core segment, second valve core segment, and third valve core segment are arranged concentrically, allowing compact integration of multiple control functions within a single valve body without increasing overall device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

Multiple valve core control functions are merged into a single integrated valve core assembly. The first, second, and third valve core segments work together within one valve cavity to achieve multiple flow passage configurations, eliminating the need for separate mechanisms and reducing overall system space requirements.

Inventive Principle:

Principle #5Merging (Combining)
