Oval Disc Valve for Multi-Passage Flow Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valves require multiple units to control communication between multiple pipelines, increasing costs, installation complexity, and maintenance difficulties.
Innovation Solution
A single oval disc valve with a simple structure that controls communication between multiple flow passages by rotating between two positions, allowing different pairs of passages to be connected or disconnected, with a rotatable mechanism and a L-shaped plate for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple conventional valves are used to control communication between multiple pipelines, then the control capability is achieved, but the cost, installation complexity, and maintenance difficulty increase significantly
Solution Approach 1:
The patent combines multiple valve functions into a single integrated valve body with multiple flow passages (first, second, and third flow passages). A single disc component performs the function of multiple separate valves by selectively blocking different passage combinations, thereby reducing the total number of valve units required while maintaining full control capability.
Solution Approach 2:
The single valve design provides multi-functionality by enabling control over multiple pipeline communications through one valve unit. The disc can be positioned to achieve different flow configurations (first and second passages connected, or first and third passages connected), making the single valve universal for controlling multiple pipeline paths.
2Adaptability or versatility
If multiple conventional valves are installed to control multiple pipelines, then the communication control is achieved, but the installation and repair difficulty increases
Solution Approach 1:
By merging multiple valve functions into a single integrated unit with a common valve body and shared disc mechanism, the patent reduces the number of components that need to be installed, positioned, and maintained. The unified structure simplifies installation procedures and reduces the complexity of repair operations compared to managing multiple separate valves.
3Adaptability or versatility
If multiple valves are used to control multiple pipelines, then the path control capability is achieved, but the cost increases greatly
Solution Approach 1:
The patent consolidates multiple valve units into a single valve assembly, reducing the total quantity of valve components required. This merging approach directly reduces material costs, manufacturing costs, and procurement costs while maintaining the capability to control multiple pipeline paths through the multi-passage design.
