Pipe Branch Connection Sealing for Interior Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices fail to achieve a reliable seal between a main pipe and a secondary pipe when the secondary pipe is mounted from the interior of the main pipe, leading to insufficient sealing and mounting difficulties.
Innovation Solution
A ring-shaped sealing element is provided that can be pressed against the main pipe, either directly or via mechanical connection elements, to ensure a secure seal, with various configurations allowing it to adapt to the inner wall or face surface of the wall opening, and can be combined with a cylindrical connection piece and fitting housing for easy mounting and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the secondary pipe is inserted through the wall opening and a sleeve is rolled on flat, then the mounting can be performed, but the sealing of the secondary pipe to the main pipe is insufficient
Solution Approach 1:
The connection device is divided into separate functional components: a connection piece with external thread for mounting, and a separate sealing element (gland) that can be adjusted independently. This segmentation allows the sealing function to be optimized separately from the mounting function, enabling reliable sealing through adjustable compression of the sealing element against the main pipe's inner wall.
Solution Approach 2:
The sealing element's compression degree can be adjusted by tightening the connection piece, changing the physical state of the sealing element from loose to compressed. This parameter adjustment enables the sealing element to adapt to different pipe dimensions and achieve reliable sealing under varying conditions.
2Reliability
If the sealing element is pressed against the main pipe by the connection piece, then the sealing quality is improved, but the mounting complexity increases
Solution Approach 1:
The sealing element is integrated with the connection piece such that the same component (connection piece) serves both to mount the secondary pipe and to compress the sealing element against the main pipe. This merging eliminates the need for separate mounting and sealing mechanisms, reducing overall device complexity while maintaining reliable sealing.
Solution Approach 2:
The connection piece performs multiple functions: it provides the external thread for mounting the secondary pipe, and simultaneously acts as a compression mechanism for the sealing element. This multi-functionality reduces the number of components needed and simplifies the overall device structure while achieving both mounting and sealing objectives.
3Reliability
If the sealing element is adapted to the inner wall of the main pipe, then the sealing effectiveness is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The sealing element's outer diameter can be adjusted or selected to match the inner diameter of the main pipe. This parameter adjustment allows the sealing element to adapt to different pipe dimensions without requiring complex adaptive mechanisms, reducing manufacturing precision requirements while maintaining sealing effectiveness.
Solution Approach 2:
The sealing element is designed to be compressible, allowing it to dynamically adapt to the inner wall contour of the main pipe when compressed by the connection piece. This dynamic adaptation capability enables the sealing element to conform to slight variations in pipe dimensions without requiring high manufacturing precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a simple and effective sealing of the connection site, ensuring a reliable seal during the mounting of the secondary pipe, even when accessed from the interior of the main pipe, by using a ring-shaped sealing element that adapts to the main pipe's dimensions and is pressed into place by the connection piece.
Implementation Method 1
the sealing element is pressed by the connection piece against the main pipe and seals the wall opening with respect to the through-flowing medium
