Bar Valve Sequential Flow Layout to Reduce Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bar valves experience pressure loss due to the mixing chamber and flow controller being located on opposing ends of the housing, requiring water flows to negotiate significant direction changes, which leads to inefficiencies in flow and pressure distribution.
Innovation Solution
The mixing chamber and flow controller are positioned sequentially along the longitudinal axis of the housing between the inlets and outlet, minimizing direction changes and reducing pressure loss, with a thermostatic temperature controller and flow control actuator for precise temperature and flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mixing chamber and flow controller are located on opposing ends of the housing, then the device can accommodate standard layout requirements, but pressure loss increases due to significant direction changes in water flow
Solution Approach 1:
The patent repositions the mixing chamber and flow controller along the longitudinal axis of the housing, utilizing the length dimension to create a sequential arrangement. This dimensional reconfiguration allows the mixed flow to travel directly from the mixing chamber through the flow controller to the outlet without requiring 180° bends, thereby reducing pressure loss while maintaining manufacturability
2Loss of energy
If the mixing chamber and flow controller are positioned sequentially along the longitudinal axis, then pressure loss is minimized and flow efficiency is improved, but the device complexity increases due to precise positioning requirements
Solution Approach 1:
The patent integrates the mixing chamber and flow controller into a unified sequential arrangement within the housing, merging their functions along the longitudinal axis. This integration reduces the need for complex interconnections and positioning mechanisms, simplifying the overall device while achieving minimized pressure loss through direct flow path configuration

AI summary
A bar valve comprising: an elongate housing having a first inlet located towards a first end of the housing, a second inlet located towards a second end of the housing, and an outlet located between the first inlet and the second inlet; a mixing chamber within the housing, the mixing chamber being configured to receive first and second input flows from the first inlet and second inlet, respectively; and a flow controller configured to receive a mixed flow from the mixing chamber and controllably output an outlet flow to the outlet; the mixing chamber and flow controller being disposed sequentially in a region of the housing between the first end and the outlet, thereby confining, the mixed flow and the outlet flow to the region of the housing between the first end and the outlet.
