Valve Assembly Closure Cover with Collar Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve arrangements face challenges in maintaining cleanliness during maintenance and replacement of valve units, as the sealing cover's width matches the base body, making handling difficult and increasing the risk of contamination and leaks.
Innovation Solution
The closure cover is designed with a smaller outline than the mounting surface, seated on a collar-shaped elevation of the base body, which acts as a barrier to prevent contaminants and liquids from entering the receiving space, and a sealing surface is formed on the collar to ensure a secure seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the closure cover has the same width as the base body, then the sealing is improved, but the handling during assembly and disassembly becomes more difficult
Solution Approach 1:
The closure cover is segmented into two functional parts: the sealing edge that matches the base body width for proper sealing, and the main body that extends beyond for easy handling. This segmentation allows each part to optimize its function independently.
Solution Approach 2:
The protruding portion of the closure cover acts as an intermediary element between the sealing function and the handling function, providing a grip area that does not interfere with the sealing edge contact with the base body.
2Ease of operation
If the closure cover is removed together with the valve unit, then the assembly and disassembly is simplified, but the risk of contamination increases
Solution Approach 1:
The closure cover is designed with integrated fastening elements that are prepared in advance to allow the valve unit to remain seated on the base body during closure cover removal, preventing contamination before it can occur.
Solution Approach 2:
The fastening function is extracted from the closure cover itself and implemented as separate fastening elements that can be independently manipulated, allowing the closure cover to be removed without necessarily removing the valve unit.
3Ease of operation
If special fastening screws are attached to the closure cap to serve as grip points, then the handling is improved, but the design effort increases
Solution Approach 1:
The handling function is merged into the closure cover structure itself by extending its body beyond the sealing edge, eliminating the need for separate fastening screws to serve as grip points.
Solution Approach 2:
The extended closure cover serves multiple functions simultaneously: it provides the sealing edge contact with the base body, provides integrated grip points for handling, and maintains structural integrity without requiring additional specialized components.

AI summary
The arrangement (1) has a valve carrier channel (57) staying in fluid connection with a valve unit (3) i.e. 5/2-way valve. A closure cover (7) of a valve carrier (2) is detachably attached at a mounting surface (12) of a base body (6). The closure cover exhibits a small outline in a plan view than the mounting surface of the base body. The closure cover rests on a frame-like collar-shaped projection (35) of the base body arranged at the mounting surface. The projection projects in a direction of the closure cover concerning an outside surrounding surface portion (12a) of the mounting surface. The base body is designed as a plate-shaped base body and a disk-shaped base body.
