Four-Way Ball Valve with Continuous Access Port Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-way ball valves do not allow fluid communication with an access port in all open and closed positions, limiting their functionality in fluid circulation systems.
Innovation Solution
A modified four-way ball valve with a fourth connector and conduit that enables fluid communication between the fourth connector and at least two of the first, second, and third connectors in each position of the ball valve member, enhancing the valve's functionality by allowing fluid communication with the access port in all positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-way ball valve is used with a separate access port, then the valve can provide basic three-way fluid control, but fluid communication with the access port is not available in all valve positions
Solution Approach 1:
The patent introduces a fourth connector positioned in a different spatial dimension (out of the plane of the first three connectors) and provides fluid communication pathways that extend into this fourth dimension. This allows the access port to communicate with the fluid circulation system regardless of the ball valve member's rotational position, as the fluid can travel through the additional spatial dimension provided by the fourth connector and its associated conduits.
Solution Approach 2:
The fourth connector and its associated fluid communication pathways enable the access port to serve multiple functions across all valve positions. The access port can simultaneously provide filling loop access, flushing capability, and system isolation functions regardless of which of the first three connectors are interconnected by the ball valve member, making the valve universally adaptable to various operational requirements.
2Adaptability or versatility
If multiple separate valves are used to achieve four-way fluid control, then complete fluid communication in all positions is possible, but the number of components and space required increases
Solution Approach 1:
The patent merges the functionality of what would traditionally require multiple separate valves into a single integrated four-way ball valve. The body houses all four connectors (first, second, third, and fourth) and the ball valve member provides centralized control of fluid pathways between all connectors, eliminating the need for multiple discrete valve components and reducing overall system space requirements.
Solution Approach 2:
The single four-way ball valve performs multiple fluid control functions that would otherwise require separate valves. The valve can interconnect any combination of the four connectors through the ball valve member's rotational positions, providing universal fluid communication capability within one compact component rather than requiring multiple specialized valves.

AI summary
A modified valve (10) comprises a body (11) having first (18), second (19), third (21) and fourth (23) connectors. The first (18) and second connectors (19) are each adapted for connection to a respective element of a fluid circulation system. A ball valve member (30) is enclosed internally within the body (11) and is arranged for selective rotation between a range of positions. First (31), second (32) and third (33) apertures are provided in the ball valve member (30) and arranged in a configuration so as selectively to permit fluid communication between at least two of said first (18), second (19) and third (21) connectors in each of said range of positions of the ball valve member (30). The ball valve member (30) further comprises a conduit (35) to permit fluid communication between said fourth connector (23) and at least two of said first (18), second (19) and third (21) connectors in each of said range of positions of the ball valve member (30).
