Modular Globe Valve Housing for Unified Casting and Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing valve technologies require different casting molds for various valve types and applications, leading to high costs and time-consuming changes, as well as inefficient manufacturing and assembly processes due to the need for specific cover designs for cone and cage valves.
Innovation Solution
A modular valve housing system that uses a standardized housing corpus and cover with interchangeable adapters for different functional or construction configurations, allowing the same housing to be adapted for various valve types and applications, reducing the need for multiple casting molds and simplifying manufacturing and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different casting molds are used for various valve types (cone valves and cage valves), then each valve type can have its specific cover design, but manufacturing costs increase and mold changes become time-consuming
Solution Approach 1:
The housing corpus is designed with a universal structure that can accommodate both cone valves and cage valves through standardized mounting interfaces. The cover is designed as a universal component that can work with different valve types, eliminating the need for separate casting molds for each valve configuration and reducing manufacturing costs while maintaining adaptability
2Reliability
If specific cover designs are created for cone and cage valves, then each valve type can be optimized for its specific function, but the number of casting molds increases and assembly time increases
Solution Approach 1:
The valve system is segmented into modular components: a standardized housing corpus, interchangeable valve elements (cone valve or cage valve), and a universal cover. This segmentation allows the cover and housing to remain constant while only the specific valve element needs to be changed, significantly reducing mold change time and assembly time while maintaining functional optimization for each valve type
3Adaptability or versatility
If multiple casting molds are maintained for different valve types, then various valve configurations can be produced, but inventory costs increase and production efficiency decreases
Solution Approach 1:
A universal housing corpus and cover design serves multiple valve types, allowing the production system to use a single mold for the housing and cover while only changing the specific valve element (cone or cage) to produce different valve configurations. This dramatically improves production efficiency by eliminating repeated mold changes while maintaining the ability to produce various valve types

AI summary
In a valve housing modular system, different configurations for a globe valve arranged to adjust a process fluid flow are provided. The globe valve can have a globe valve member movable in translation along a stroke axis. The system can include a housing corpus with a process fluid inlet and outlet, a process fluid passage arranged therebetween, and an actuating opening to introduce the rod for actuating the globe valve member along the stroke axis; and a housing cover for covering the actuating opening. The system can include different adapters for the different functional/structural configurations.
