Velocity Reduction Discharge Plate for Fluid Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems produce fluid discharge with constantly changing diameter and aeration, leading to unpredictable and potentially harmful downstream impacts due to varying velocity and distance traveled, which existing technologies fail to optimize effectively.
Innovation Solution
A velocity reduction discharge plate with radially extending ribs and slots, designed to attach to the outlet of valves or pipes, reduces exit velocity by increasing the slot area to at least four times the inlet cross-sectional area, allowing for uniform discharge and incidental aeration, thereby reducing the horizontal travel distance and impact of the fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed cone valve is used to control fluid flow, then the valve structure is simple, but the fluid discharge produces constantly changing diameter and unpredictable downstream impacts
Solution Approach 1:
The discharge plate segments the fluid flow by introducing multiple radial slots that divide the continuous jet into discrete flow paths. This segmentation creates a blended cylindrical column of aerated water with constant diameter, eliminating the constantly changing conical shape and producing predictable downstream discharge patterns.
Solution Approach 2:
The discharge plate introduces localized aeration through radial slots at specific positions in the flow path. This local quality change transforms the discharge from a dense conical jet to a blended cylindrical column with uniform aerated characteristics, ensuring predictable travel distance and impact.
2Speed
If the valve outlet area is reduced to decrease velocity, then the discharge velocity is reduced, but the discharge coefficient decreases below 0.4
Solution Approach 1:
The discharge plate transitions the flow from a two-dimensional conical jet to a three-dimensional blended cylindrical column by introducing radial aeration slots. This dimensional change allows velocity reduction while maintaining a discharge coefficient greater than 0.4 through the creation of a uniform aerated flow pattern.
3Quantity of substance
If the fluid discharge velocity is high, then the discharge volume is maintained, but the horizontal travel distance increases causing harmful downstream impacts
Solution Approach 1:
The discharge plate converts the harmful high-velocity conical jet into a beneficial blended cylindrical column of aerated water. By introducing radial aeration slots, the system transforms the dangerous concentrated flow into a uniform dispersed flow with reduced horizontal travel distance, eliminating downstream harm while maintaining discharge volume.

AI summary
A discharge for a fluid system has an inlet and an outlet in which a fluid flows from the discharge inlet to the discharge outlet. The discharge inlet has a inlet cross-sectional area. The discharge outlet has a plate. The plate has a plurality of radially extending ribs. The radially extending ribs are equiangularly spaced about a center axis of the plate. The radially extending ribs define a plurality of radially extending slots between the equiangularly spaced apart ribs. The radially extending ribs are dimensioned such that a sum of an area of all of the radially extending slots is greater than the discharge inlet cross-sectional area. When the fluid flows through the plate slots from the discharge outlet, it has a discharge coefficient of greater than 0.4.
