Valve Device for Industrial Filters with Centering Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current valve devices for cleaning industrial filters require rods for assembly, leading to material waste, increased production time, and potential operational issues due to welding residues, as well as tank deformation without clear end stops for proper screwing.
Innovation Solution
A valve device with a monolithic main body and improved lance design that eliminates the need for rods, utilizing a saddle and ring nut assembly with locking fins for secure mounting and centering within the tank, preventing deformation and reducing assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rods are welded to the tank at each valve, then the tank deformation is limited, but the production time increases and material cost increases
Solution Approach 1:
The patent removes the rods from the assembly process entirely. Instead of welding rods to limit tank deformation, the design uses the lance structure itself with integrated features (such as the lance body and mounting brackets) to achieve the same deformation limitation function, thereby eliminating the need for separate rod components and their associated welding operations.
Solution Approach 2:
The patent combines the deformation limitation function into the lance structure itself. The lance is designed with integrated mounting features and structural elements that perform both the air delivery function and the tank deformation limitation function, eliminating the need for separate rod components.

3Stability of the object's composition
If rods are welded to the tank at each valve, then the tank deformation is limited, but welding residues may cause operational problems
Solution Approach 1:
The patent removes the rods from the assembly process entirely. Instead of welding rods to limit tank deformation, the design uses the lance structure itself with integrated features (such as the lance body and mounting brackets) to achieve the same deformation limitation function, thereby eliminating the need for separate rod components and their associated welding operations.
4Device complexity
If the lance is screwed into the valve without end stops, then the assembly is simple, but the operator cannot know when to stop screwing causing excessive deformation
Solution Approach 1:
The patent incorporates end stops or positioning features into the lance or valve assembly that are pre-configured to automatically indicate when the correct screwing depth is reached. This preliminary structural arrangement eliminates the need for operator judgment while maintaining assembly simplicity.
Solution Approach 2:
The lance or valve assembly includes built-in features (such as threaded sections with defined engagement lengths, positioning ribs, or mechanical stops) that automatically control the screwing depth, allowing the assembly to self-regulate without requiring external guidance or complex control mechanisms.
