Guided Ball Relief Valve Structure for Low Vibration Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relief valves experience vibration and noise due to the ball's movement in multiple directions when opening and closing, and the conical shape of the ball holding portion causes integral vibration with the ball, leading to increased noise.
Innovation Solution
A valve design featuring a guiding part that restricts the valve body's movement to a predetermined direction, preventing swinging and integral movement with the pressing member, thereby minimizing vibration and noise. The guiding part includes an inclined surface that abuts the valve body at two points, ensuring consistent flow path positioning and reducing vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ball holding portion has a conical shape to grip the ball, then the ball can be held securely, but the ball holding portion moves integrally with the ball causing vibration and increased noise
Solution Approach 1:
The pressing member is divided into distinct functional parts: a pressing portion that contacts the ball and a guiding portion that provides directional guidance. This segmentation allows the pressing member to apply force while restricting movement, preventing integral vibration between the ball and holding portion.
Solution Approach 2:
The guiding portion acts as an intermediary structure between the ball and the ball holding portion. It mediates the interaction by providing a constrained path for ball movement, thereby preventing direct integral movement and vibration between the ball and the holding portion.
2Ease of operation
If the ball is allowed to move freely when separated from the wide-width portion, then the valve can open and close, but the ball moves in multiple directions causing vibration
Solution Approach 1:
The guiding portion provides dynamic guidance that adapts to the ball's movement during valve operation. It allows the ball to move freely in the axial direction for opening and closing while dynamically constraining radial movements, thereby preventing vibration during operation.
Solution Approach 2:
The guiding portion changes the effective degrees of freedom available to the ball depending on the operational state. During normal operation, it permits axial movement while constraining radial movement, effectively changing the movement parameters to prevent vibration.
Applied Scientific Principles
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 valve body is prevented from vibrating and swinging, reducing abnormal noise, and the valve operates reliably with improved noise reduction by guiding the valve body in a single direction, maintaining consistent flow path positioning.
Implementation Method 1
a guiding part that separates the valve body away from the valve seat while relatively moving the valve body in a predetermined one direction
Implementation Method 2
a pressing member that presses the valve body toward the valve hole
Implementation Method 3
the valve body closes the valve hole provided in the valve seat

AI summary
A valve of the present disclosure includes a valve seat formed with a valve hole; a spherical valve body; and a pressing member that presses the valve body toward the valve hole, the valve hole being closed by the valve body pressed by the pressing member; where the pressing member includes a guiding part that, when a force opposing the urging force acts on the valve body by greater than or equal to a prescribed value, separates the valve body away from the valve seat while guiding and relatively moving the valve body in a predetermined one direction.
