Expansion Vessel Connection With Integrated O-Ring Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure expansion vessels require complex and time-consuming manual application of sealing materials like hemp or sealing tape for a pressure-tight connection to a line network, necessitating skilled assembly personnel.
Innovation Solution
The connecting piece of the pressure expansion vessel features a radially projecting annular projection with a circumferential sealing surface, accommodating a sealing element that forms a seal between the connecting piece and the tubular fitting, eliminating the need for manual sealing and enhancing the sealing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual sealing with hemp or sealing tape is used for connecting the expansion vessel to the line network, then a pressure-tight connection can be achieved, but the assembly process becomes complex and time-consuming, requiring skilled personnel
Solution Approach 1:
The sealing element is pre-installed on the connecting piece during manufacturing, positioned in advance to perform the sealing function. This eliminates the need for assembly personnel to manually apply sealing materials, simplifying the assembly process while ensuring reliable pressure-tight connection.
Solution Approach 2:
The connecting piece is designed to be self-sealing through the integrated sealing element that automatically forms a seal when the connecting piece is screwed into the tubular fitting. The system serves itself by incorporating the sealing function directly into the connecting piece, eliminating the need for external sealing materials and manual sealing operations.

AI summary
The tank (1) has a tank inner area divided into water and gas areas (4, 5) by a separating unit, where the water area is connected with a tube-shaped molded part of a distribution network over a connecting piece (7) in a pressure-tight manner. The connecting piece has a radially projecting ring-shaped attachment piece that has a circulating sealing surface on a side of the network, where the side is turned towards the molded piece. A sealing unit i.e. O-ring seal, lies at the sealing surface and arranged on the connecting piece, where the sealing surface is formed by a circulating groove.
