Pipeline Insertion Guide Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion apparatuses for pressurized pipelines face challenges in efficient installation, durability, and minimizing fluid leaks, particularly due to wear and tear issues that require frequent replacement of parts and increase the risk of leaks during operations.
Innovation Solution
The insertion apparatus features an insertion guide with a guide seal packing and coupling nut, combined with a connection adapter that forms a sealed union joint, allowing for efficient assembly and installation while enabling easy replacement of damaged components, thus extending the life of the more expensive parts and reducing the risk of fluid leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insertion apparatus uses traditional connection methods with multiple parts, then it provides basic functionality, but it increases the risk of fluid leaks and reduces installation efficiency
Solution Approach 1:
The patent combines multiple connection components (adapter, seal, coupling elements) into an integrated connection assembly where the seal is incorporated directly into the adapter structure. This merging of components reduces the number of separate parts that could potentially leak while maintaining reliable sealing through the integrated design.
2Duration of action of stationary object
If the insertion apparatus uses wear-resistant materials for all parts, then it improves durability, but it increases the cost and complexity of the apparatus
Solution Approach 1:
The patent applies different material properties to different parts of the connection assembly based on their specific functional requirements. The adapter uses materials optimized for structural integrity and connection stability, while the seal uses materials specifically selected for wear resistance and sealing performance. This localized material selection improves overall durability without requiring all components to be made from expensive, wear-resistant materials.
3Reliability
If the insertion apparatus uses a sealed connection design, then it minimizes fluid leaks, but it makes maintenance and part replacement more difficult
Solution Approach 1:
The patent segments the connection assembly into distinct, modular components (adapter, seal, coupling elements) that can be independently replaced. The seal is designed as a separate element that can be accessed and replaced without dismantling the entire connection structure, maintaining sealing integrity while facilitating easy maintenance.
4Ease of operation
If the insertion apparatus uses a simple connection design, then it enables easy assembly and disassembly, but it increases the risk of fluid leaks
Solution Approach 1:
The patent incorporates pre-formed sealing elements and pre-configured connection geometries that ensure proper sealing alignment during assembly. The seal is pre-positioned in the adapter with alignment features that guide correct installation, allowing for quick assembly while maintaining reliable sealing performance without complex alignment procedures.
