Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fluid transmission pipelines suffer from poor sealing performance and inability to meet leakage prevention standards, especially in high temperature environments, due to thread connections between pipe fittings.
Innovation Solution
A compression teeth ring connection pipe fitting that includes a pipe fitting body with flared sections and a sealing component comprising a sealing ring, high temperature sealing ring, and teeth ring, which are coaxially arranged to provide enhanced sealing and stability, allowing for reliable connection even in high temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thread connections are used between pipe fittings, then the connection can be assembled, but the sealing performance is poor and leakage prevention standards cannot be met
Solution Approach 1:
The sealing component is divided into multiple independent rings: a sealing ring for general sealing, a high temperature sealing ring for elevated temperature conditions, and a teeth ring for mechanical interlocking. This segmentation allows each ring to perform its specific function optimally, achieving reliable sealing that thread connections cannot provide.
Solution Approach 2:
The patent uses composite sealing structures combining different material properties - the sealing ring (likely elastomeric), high temperature sealing ring (heat-resistant material), and teeth ring (rigid interlocking structure). This composite approach provides superior sealing performance compared to single-thread connections.
2Reliability
If traditional pipe fittings are used in high temperature environments, then the pipeline can operate, but leakage prevention standards cannot be met
Solution Approach 1:
The patent applies local quality by using a specialized high temperature sealing ring made of heat-resistant material specifically at the sealing location where high temperature exposure occurs. This targeted approach ensures leakage prevention in high temperature environments without requiring the entire pipeline system to be designed for extreme temperatures.
3Productivity
If thread connections are used, then pipe fittings can be connected, but installation efficiency is low
Solution Approach 1:
The sealing rings and teeth ring are pre-assembled into the pipe fitting body before field installation. This preliminary action eliminates the need for complex threading operations during installation, allowing workers to simply insert and connect the fittings, thereby significantly improving installation efficiency.
4Reliability
If a single sealing ring is used, then the structure is simple, but sealing performance is insufficient under high temperature and pressure
Solution Approach 1:
The sealing system is segmented into three functional rings: a sealing ring for basic sealing, a high temperature sealing ring for thermal resistance, and a teeth ring for mechanical interlocking and positioning. This segmentation enables the sealing system to maintain performance under high temperature and pressure conditions that would fail a single-ring design.
Solution Approach 2:
The three sealing rings are nested coaxially within the pipe fitting body, with each ring positioned in its own groove. This nested arrangement maximizes the use of space while providing multiple layers of sealing protection, ensuring reliable sealing performance under extreme conditions.
