Valve Actuator Suspension Structure for Clean Vertical Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve actuating devices in water filtration systems are complex, difficult to operate, and prone to secondary pollution due to their intricate structure, which complicates the separation of the valve seat and body, hindering the smooth flow of liquids.
Innovation Solution
A valve actuating device with a simple structure featuring a body and suspension device, such as a claw with a protrusion and connecting arm, that penetrates through holes in the valve seat to separate the valve body from the seat, allowing liquid flow and easy operation by hand, without additional fixing, and can be made of materials like PP, PE, or nylon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spiral axial movement mechanism is used to actuate the valve, then the valve can be opened and closed, but the structure becomes complicated and operation becomes difficult
Solution Approach 1:
The patent extracts the complex spiral axial movement mechanism and replaces it with a simple lifting motion. The valve body is separated from the valve seat through vertical displacement only, removing unnecessary rotational and axial components while achieving the same valve opening function.
Solution Approach 2:
Instead of using a spiral motion that combines rotation and axial movement, the patent inverts the approach by using pure vertical lifting motion. The valve body is lifted straight up from the valve seat through the through-hole, achieving valve opening without any rotational component.
2Object-affected harmful factors
If the valve structure is complex, then the valve can be sealed properly, but it causes secondary pollution and is difficult to operate from inside the liquid container
Solution Approach 1:
The patent segments the valve body from the valve seat, allowing the valve body to be completely separated and lifted through the through-hole. This segmentation enables simple external operation without complex internal mechanisms, reducing the risk of secondary pollution from complicated internal structures.
Solution Approach 2:
The patent changes the operational dimension from internal spiral motion to external vertical lifting. By moving the valve body vertically through the through-hole from the outside, the operation becomes simpler and less prone to causing secondary pollution compared to internal mechanisms.
3Productivity
If the valve body is tightly sealed to the valve seat, then the valve closes properly, but it hinders smooth liquid flow when open
Solution Approach 1:
The patent designs the valve body with a lifting action that preliminarily separates it from the valve seat through the through-hole before full opening. This preliminary separation ensures smooth liquid flow path is established early, while the valve body maintains sealing capability when closed through proper positioning.
