Valve Control Chamber Damping via Throttled Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valves with a two-part control chamber experience undesirable oscillations when actuated by pressure medium, leading to noise and potential destruction due to the piston and spring system acting as an oscillating system.
Innovation Solution
The control chamber is divided into two separate chambers, with a throttle connecting them, slowing down pressure medium transition and creating negative pressure to counteract movement, thereby damping the oscillations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressure medium is applied to the control chamber to actuate the valve, then the valve opens and pressure medium can flow from inlet to outlet, but the piston oscillates causing noise and potential destruction
Solution Approach 1:
The control chamber is divided into two separate chambers: a first control chamber and a second control chamber. This segmentation allows the pressure medium to act in a controlled sequence, first building pressure in the first chamber and then transferring it to the second chamber through a throttle, thereby preventing direct uncontrolled action on the piston and eliminating oscillations
Solution Approach 2:
A throttle is introduced as an intermediary element between the first control chamber and the second control chamber. This throttle mediates the pressure medium flow, slowing it down and creating a pressure differential that dampens piston movement and prevents oscillatory behavior while still enabling valve actuation
2Object-generated harmful factors
If the control chamber is divided into two chambers with a throttle, then piston oscillations are damped and noise is reduced, but the device complexity increases
Solution Approach 1:
The throttle serves multiple functions simultaneously: it acts as a flow restriction element, a pressure differential creator, and a damping mechanism. By making this single component multi-functional, the patent achieves oscillation damping without proportionally increasing device complexity
Solution Approach 2:
The second control chamber is effectively nested within the overall valve structure, with the throttle forming a connection pathway from the first chamber. This nested arrangement allows the two-chamber system to be integrated into the existing valve geometry with minimal additional space and structural complexity
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
This solution effectively prevents vibrations in the actuating means, resulting in low-noise and robust valve operation.
Implementation Method 1
the pressure medium is slowed down by a throttle during the transition from the first to the second chamber
Implementation Method 2
a movement of the actuating means creates a negative pressure in the second chamber, since pressure equalization between the first and second chambers cannot take place sufficiently quickly
Implementation Method 3
The piston is biased by a spring in such a way that no pressure medium can flow from the inlet chamber into the outlet chamber
