Modular Valve Block Assembly for Tool-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing process valves require complex maintenance procedures, necessitating the removal of outer actuators and the availability of various manifold or valve block sizes, leading to high maintenance costs and inventory management challenges.
Innovation Solution
A modular valve body design with a module connection and locking mechanism that allows for tool-free assembly and disassembly, enabling customizable valve blocks with simplified maintenance and reduced production costs through a twist-and-plug motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional process valves are used with fixed valve blocks, then structural stability is maintained, but maintenance complexity increases and inventory management becomes difficult
Solution Approach 1:
The valve body is divided into modular sections with standardized module connections that allow individual valve bodies to be separated and reconfigured. The module connection includes standardized locking elements and sealing sections that enable easy segmentation and reassembly of the valve block without requiring complex tools or procedures.
2Adaptability or versatility
If multiple valve block sizes are kept in stock for maintenance, then replacement flexibility is improved, but inventory costs increase
Solution Approach 1:
The module connection is designed with universal dimensions and features that allow the same standardized valve body modules to be used across different valve block configurations. The standardized opening sizes, module connection interfaces, and locking mechanisms enable a single set of modular valve bodies to replace multiple fixed-size valve blocks, eliminating the need to maintain various sizes in inventory.
3Ease of operation
If modular valve bodies with locking mechanisms are used, then assembly ease is improved, but sealing reliability may be compromised
Solution Approach 1:
The sealing function is extracted as a separate, dedicated component within the module connection - specifically the sealing section with sealing elements that are independent from the locking mechanism. This separation allows the sealing elements to be optimized for fluid-tight performance while the locking elements focus solely on mechanical connection and positioning, ensuring both assembly ease and sealing reliability without compromise.

AI summary
A modular first valve body (100a) for a process valve is proposed. The valve body (100a) comprises at least one internal fluid channel (102) which fluid-carries and connects at least two openings of the valve body (100a). At least one of the openings is surrounded by a module connection (200) that can be connected to a mating module connection of another valve body.
