One-Way Valve Structure for Easier Plugging Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of one-way valves with a plugging function is inconvenient due to the need to install multiple parts in a narrow flow port, particularly with integrated valve bodies that require snap springs, making the process cumbersome and prone to errors.
Innovation Solution
A one-way valve design featuring a plugging portion and valve body that are processed independently, allowing for separate assembly of the piston portion on the valve body before connection, which avoids the need for assembly in a narrow flow port and facilitates easier assembly by using an elastic member to control the piston head's movement and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an integrated valve body is used to achieve plugging function, then the plugging function is integrated, but the assembly operation becomes inconvenient and complex
Solution Approach 1:
The valve body is divided into separate components: the main valve body and the plugging portion are processed independently and then connected. The piston portion is assembled on the valve body first, and then the plugging portion is connected separately. This segmentation allows each component to be manufactured and assembled independently, avoiding the complexity of assembling multiple parts through a narrow flow port while maintaining the integrated plugging function.
2Adaptability or versatility
If multiple parts are installed in a narrow flow cavity, then the plugging function is achieved, but the assembly process becomes cumbersome and error-prone
Solution Approach 1:
The valve structure is segmented into distinct components that can be assembled in a logical sequence. The piston portion is assembled on the valve body first, followed by connecting the plugging portion. This reduces assembly complexity by avoiding the need to install multiple small parts through a narrow flow port simultaneously.
Solution Approach 2:
The piston portion is assembled on the valve body before the plugging portion is connected. This preliminary assembly step allows for easier access and manipulation of components during assembly, reducing the risk of errors and making the overall process less cumbersome.
3Adaptability or versatility
If assembly is performed at the flow port, then the one-way valve function is achieved, but the assembly operation is very inconvenient
Solution Approach 1:
The valve body is segmented into the main valve body and the plugging portion, allowing assembly to be performed on the main valve body where access is easier, rather than through the narrow flow port. The plugging portion is then connected separately, maintaining the one-way conduction function while improving assembly convenience.

Function Achieved in This Case
This design simplifies the assembly process, reduces the risk of errors, and enhances the sealing capacity and structural stability of the one-way valve by allowing independent processing and connection of the plugging portion and valve body, making the assembly more efficient and reliable.
Implementation Method 1
an elastic member, which is disposed inside the flow cavity, wherein a first end of the elastic member abuts against the valve body, and a second end of the elastic member abuts against the limiting cap
