Ball Valve Trim Assembly With Noise-Suppressing Ring Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ball valves in industrial facilities often experience excessive vibration due to high fluid flow rates, leading to loud noise that exceeds acceptable safety levels, and existing countermeasures are labor-intensive and costly.
Innovation Solution
The development of a noise-suppressing trim for ball valves that simplifies the manufacturing process by eliminating the need to heat the throttling ball, thereby reducing labor and costs, and incorporating noise-reducing elements that are either integral to the annular ring or secured separately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional trim installation methods are used, then noise suppression is achieved, but labor intensity and production costs increase due to heating requirements
Solution Approach 1:
The noise suppression features are merged directly into the throttling ball component itself, creating an integrated design where the trim pieces containing noise-suppressing features are formed as part of the ball rather than being separate components requiring heating for installation
Solution Approach 2:
The noise suppression function is extracted and embodied directly in the throttling ball through integrally formed trim pieces, eliminating the need for separate heating and installation processes that were previously required for attached trim components
2Object-affected harmful factors
If traditional trim installation methods are used, then noise suppression is achieved, but assembly time increases due to heating and pre-heating processes
Solution Approach 1:
The trim pieces are merged with the throttling ball in an integral construction, allowing the noise suppression features to be built-in during the primary manufacturing process rather than requiring separate heating and installation steps that extend assembly time
Solution Approach 2:
The noise suppression features are incorporated into the throttling ball design during the initial manufacturing stage, so that when the ball is assembled into the valve, the noise suppression functionality is already in place without requiring additional heating or preparation steps

AI summary
A trim device for a ball valve that is configured to reduce noise. The trim device may embody a portion of an annular ring. This portion may include a noise-suppressing element, for example, openings of a shape that can modify flow of material as it passes through the ball valve. In one implementation, the portion of the annular ring fits into an opening in a throttling ball, preferably without heating the throttling ball.
