Curved Connection Fitting Reduces Pressure Loss in Water Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking and process water systems experience significant pressure losses when the ring main flow is reintroduced into the riser pipe string, leading to inefficiencies and low volume flow, especially when no water is drawn from connected consumers.
Innovation Solution
The ring main flow is reintroduced into the riser pipe string in an arcual manner, approximating a tangential approach, and the threading-out process occurs in a bend, minimizing pressure losses. Additionally, a guide element and offset central axes within the connection fitting reduce flow resistance, and smaller outlet and threading openings enhance flow velocity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ring main flow is reintroduced straight into the riser pipe string at an angle of no more than 75° to the main flow direction, then the connection fitting is easier to install, but considerable pressure losses still occur
Solution Approach 1:
The threading-in or threading-out channel opening into the line channel opens in the form of an arc or a segment of a circle, allowing the ring main flow to approach the main flow direction tangentially. This curved geometry eliminates sharp angles and creates a smooth flow transition, significantly reducing pressure losses while maintaining ease of installation
2Stability of the object's composition
If the ring line is introduced at an angle of approximately 90° to the main flow direction, then the flow separation is reduced, but the connection fitting becomes more complex and pressure losses increase
Solution Approach 1:
The arc-shaped or segmental threading-in/threading-out channel opening creates a gradual flow transition that maintains flow stability without requiring a 90° introduction angle. The curved geometry allows the ring main flow to merge smoothly with the main flow direction, achieving flow stability with minimal pressure loss
3Quantity of substance
If a narrowing of the cross section is generated to create a Venturi effect, then negative pressure is generated to increase volume flow, but the connection fitting becomes more complex and pressure losses increase
Solution Approach 1:
The curved, arc-shaped threading channel opening naturally guides the ring main flow to approach tangentially, creating efficient flow patterns without requiring Venturi effect narrowing. This geometric solution increases volume flow through improved flow dynamics while avoiding the complexity and pressure losses associated with cross-sectional narrowing

Function Achieved in This Case
This configuration significantly reduces pressure losses and increases the volume flow through the system, ensuring efficient water distribution even when no water is drawn from connected consumers, while being easy to install and produce.
Implementation Method 1
the ring main flow approaches the main flow direction in the riser pipe line approximately tangentially, so that the pressure losses are further reduced
Implementation Method 2
the parts of the flow separate approximately tangentially through the riser pipe, so that the pressure losses are also further reduced
