Valve Pipeline Structure With Segmented Flow Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline structures with valves experience unstable fluid flow due to interference from internal components, leading to blockages and flow disruptions.
Innovation Solution
A pipeline structure with a flow controller that includes a connection pipe with separate inlet and outlet channels, an accommodation part with upper and lower flow chambers, and a flow controller that selectively enables or interrupts fluid communication between these chambers, using a magnetic system to manage fluid flow without interference from elastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flow controller with elastic pad is disposed in the pipeline to control flow supply, then flow control capability is improved, but internal components interfere with fluid communication causing unstable flow
Solution Approach 1:
The flow chamber is divided into upper and lower sections separated by an elastic pad, with dedicated inlet channels for each section. This segmentation isolates the elastic pad's deformation to specific zones, preventing interference with overall fluid communication stability.
Solution Approach 2:
A magnetic field is introduced as an intermediary control mechanism to actuate the flow controller, replacing direct mechanical contact with the elastic pad. The magnetic field enables remote control of the elastic pad deformation, eliminating mechanical interference in the fluid path.
2Ease of operation
If internal components of the flow controller are disposed in the fluid path, then flow control function is achieved, but blockages occur causing unstable flow supply
Solution Approach 1:
The elastic pad is extracted from direct contact with the main fluid path and positioned within the flow chamber, actuated by magnetic field rather than mechanical push. This removes the primary blockage source from the critical fluid communication path between inlet and outlet.
Solution Approach 2:
The mechanical actuation system is replaced with a magnetic field-based actuation system. The magnetic field remotely controls the elastic pad without requiring mechanical components in the fluid path, eliminating mechanical interference and blockage risks.
3Device complexity
If elastic pad deformation is used to control fluid communication, then flow control is simplified, but elastic deformation interferes with stable fluid communication
Solution Approach 1:
A magnetic field is introduced as an intermediary control mechanism to actuate the flow controller, replacing direct mechanical contact with the elastic pad. The magnetic field enables remote control of the elastic pad deformation, eliminating mechanical interference in the fluid path.
Solution Approach 2:
The control mechanism changes from mechanical displacement to magnetic field strength variation. By changing the magnetic field parameters (strength, direction), the elastic pad deformation is precisely controlled without mechanical contact, maintaining simplicity while improving stability.

AI summary
A pipeline structure (1) includes a connection pipe (10) and a flow controller (20). The connection pipe (10) includes inflow and outflow passages (100, 200) and an accommodation part (300) that is located therebetween and has upper and lower flow chambers (311, 312) in fluid communication with each other, first and second inlet channels (320, 330) and an outlet channel (340). The first inlet channel (320) is in fluid communication with the inflow passage (100) and the upper flow chamber (311), and is formed by a side wall standing at the inflow passage (100). The second inlet channel (330) is in fluid communication with the inflow passage (100) and the lower flow chamber (312). The outlet channel (340) is in fluid communication with the lower flow chamber (312) and the outflow passage (200). The flow controller (20) enables or interrupts fluid communications between the upper and lower flow chambers (311, 312) and between the second inlet channel (330) and the lower flow chamber (312).
