Pipe Connection Seal Support for Adjustable Clamping and Pull-Out Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connection devices struggle to create a permanently tight and pull-out-proof connection for pipes with varying outer diameters, particularly in water pipes experiencing high pressures and soil movements, as clamping rings often compromise sealing and tensile strength.
Innovation Solution
A pipe connection device with a sleeve, clamping body, adjustable clamping ring, and seal system, featuring a seal carrier and securing wedges with guide devices, ensures a mechanically stable and sealed connection by adjusting the inner diameter and using braking elements to prevent pull-out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clamping ring with adjustable inner diameter is used to adapt to different pipe outer diameters, then adaptability is improved, but sealing reliability and tensile strength deteriorate
Solution Approach 1:
The clamping ring is divided into multiple clamping segments that can move relative to each other, allowing the inner diameter to be adjusted while maintaining structural integrity. Each segment can be independently positioned to adapt to different pipe diameters without compromising the overall sealing and tensile strength of the connection
Solution Approach 2:
A seal carrier is introduced as an intermediary component between the seal and the clamping ring. The seal carrier provides a stable mounting surface for the seal, ensuring reliable sealing independent of the clamping ring's adjustable diameter, thus resolving the conflict between adaptability and sealing reliability
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 device provides a secure, leak-proof connection that maintains sealing integrity even under high pressures and soil movements, preventing pipe disconnection without requiring hard stops or complex assembly.
Implementation Method 1
the seal extends with a sleeve section in a ring shape between the sleeve and the clamping ring in order to seal this area
Implementation Method 2
the clamping ring is designed in such a way that it is clamped between the sleeve and the clamping body and pressed towards the pipe end by tensioning or tightening the clamping means
