Anti-Oscillation Braking Mechanism for Livestock Waterer Float Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic float valves for livestock water troughs experience oscillations during filling, leading to operational disruptions, noise pollution, and potential pipe deterioration due to insufficient pressure to instantly counteract water network pressure, causing resonance and wear on system components.
Innovation Solution
The implementation of an anti-oscillation device with a braking mechanism that opposes resistance to the valve's closing movement, ensuring the valve only closes when the water level is sufficient to overcome this resistance, preventing oscillations and maintaining a stable closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional automatic float valve is used to fill the drinking trough tank, then the valve can control water supply based on water level, but oscillations occur during filling when approaching the predefined filling level due to insufficient pressure to counteract network water pressure
Solution Approach 1:
The patent applies preliminary anti-action by introducing a braking means that creates resistance to the valve holder's closing movement before the valve actually closes. This resistance opposes the closing force generated by the float, preventing the valve from slamming shut when water pressure is insufficient to immediately counteract the network pressure. The braking means is configured to provide this counteracting force in advance, eliminating the oscillation problem at its source.
Solution Approach 2:
The braking means acts as an intermediary element between the valve holder and the valve seat. It mediates the closing action by introducing a controlled resistance that smooths the transition from open to closed position. This intermediary mechanism prevents direct impact and oscillation by distributing the closing force over a longer time period, thereby reducing noise and mechanical stress on the system components.
2Productivity
If the valve closes rapidly to stop water flow, then water supply is effectively blocked, but excessive stress is exerted on pipes and valve elements leading to deterioration and potential rupture
Solution Approach 1:
The braking means provides beforehand cushioning by creating a damping effect during the valve closing process. This cushioning resistance is applied before the valve fully closes, absorbing the shock and reducing the impact force on pipes and valve elements. The braking means ensures that the valve closes in a controlled manner, preventing water hammer effects and excessive stress that would otherwise lead to component deterioration or pipe rupture.
3Speed
If the valve holder is allowed to move freely to control water flow, then the valve responds quickly to water level changes, but oscillations are generated that disrupt operation and create noise pollution
Solution Approach 1:
The braking means introduces a dynamic resistance that adapts during the valve closing process. The resistance is not constant but varies based on the valve holder's position and movement speed. This dynamic braking effect allows the valve to respond quickly to water level changes while simultaneously dampening oscillations and reducing noise. The braking means is configured to provide appropriate resistance at different stages of closure, maintaining both responsiveness and quiet operation.
