One Way Valve Assembly with Radial Gap for Easy Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional one-way valves are difficult to assemble and disassemble, especially when the valve seat is welded to a container's sidewall, which hampers installation and replacement efficiency and increases production costs.
Innovation Solution
A one-way valve design featuring a valve seat with an outer and inner circular base and radial ribs, along with a valve member comprising a membrane and rod portion, where the rod can be inserted through a gap in the inner circular base, allowing for easier assembly and disassembly by accommodating deformation for fluid flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve seat is welded to the container sidewall to ensure secure mounting, then the mounting reliability is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The valve seat is divided into two separate parts: a base member that is welded to the container sidewall, and a valve body that can be independently assembled and disassembled. The membrane is then assembled to the valve body, allowing the membrane assembly to be easily replaced without affecting the welded connection to the container.
Solution Approach 2:
The membrane assembly (including the membrane and valve body) is extracted as a separate removable component from the welded base member. This allows the membrane to be easily replaced by detaching it from the base member through the opening, while the base member remains permanently secured to the container.
2Reliability
If the membrane is tightly secured to the valve seat to ensure sealing, then the sealing performance is improved, but the ease of replacement deteriorates
Solution Approach 1:
The valve assembly is segmented into a permanent base member (with welded connection to container) and a removable valve body with membrane. This segmentation allows the membrane to be easily replaced by removing the valve body from the base member, while maintaining proper sealing when assembled.
Solution Approach 2:
The membrane and valve body are extracted as a removable assembly from the welded base member. The valve body can be detached from the base member through the opening, allowing easy membrane replacement while ensuring proper sealing when reassembled.
3Reliability
If the valve structure is made complex to improve fluid control, then the fluid control performance is improved, but the production efficiency deteriorates
Solution Approach 1:
The valve is segmented into modular components (base member, valve body, membrane) that can be manufactured separately and assembled. This modular approach maintains fluid control functionality while simplifying manufacturing and assembly processes, thereby improving production efficiency.
Solution Approach 2:
The base member with welded connection serves multiple functions: providing structural support, ensuring secure mounting to the container, and serving as a mounting platform for the valve body. This multi-functionality reduces the need for additional components, simplifying the overall structure and improving production efficiency.

AI summary
A one way valve is revealed. The one way valve includes a valve seat and a valve member supported by the valve seat. A hole is mounted at a center of the valve base while an outer circular base is disposed around the hole and an inner circular base is arranged at a center of the hole. The inner circular base has a circular sidewall around an opening. At least one gap is radially formed on the circular sidewall and the gap is vertically penetrating the circular sidewall. The valve member consists of a membrane portion and a rod portion extended from one side of the membrane portion. Thereby the rod portion is passed through the gap of the inner circular base to be set into the opening of the inner circular base.
