Float Valve Support Structure for Stable Seat Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stability of seating a float on a valve seat in existing valve devices is compromised due to decreased position accuracy of the float seat, leading to instability in valve operation.
Innovation Solution
A valve device design that includes a support system with a base having a frame shape and two float seats, which provides three-point support to the float when it is seated on the valve seat, enhancing stability and maintaining high position accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single float seat is used to support the float on the valve seat, then the structure is simple, but the position accuracy and stability of the float decrease
Solution Approach 1:
The single float seat is divided into two separate float seats (first float seat and second float seat) that are positioned at different locations. This segmentation allows the float to be supported at multiple points, improving position accuracy and stability without requiring a single complex support structure.
Solution Approach 2:
The support system transitions from a single-point support to a multi-point support distributed in different spatial dimensions. The two float seats are arranged at different positions (one at the front end and one at the rear end of the base), creating a three-point support system that enhances positional stability through spatial distribution.
2Stability of the object's composition
If a single float seat is used, then the device structure is simple, but the stability of seating the float on the valve seat decreases
Solution Approach 1:
The support function is segmented into multiple float seats instead of using a single float seat. This allows the float to be stably supported at multiple contact points on the valve seat, preventing instability and ensuring reliable seating even under external shocks or varying fluid conditions.
Solution Approach 2:
Different parts of the support system (first float seat and second float seat) are positioned at different locations to provide localized support where needed. The front float seat and rear float seat each contribute to stability at their respective positions, creating overall system stability through distributed local support points.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The enhanced support system significantly improves the stability of the float's seating on the valve seat, maintaining accurate positioning and ensuring reliable valve operation even under external shocks or varying fluid conditions.
