Pipe Branch Coupling Assembly With Pressurized Gasket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe branching methods require extensive assembly time and materials, leading to high construction costs, and are prone to fluid leakage when the diameter of the branch hole is increased to enhance flow rate.
Innovation Solution
A coupling assembly featuring a branch hole in the inflow pipe, a communicating branch pipe, and a coupler with a body part and gasket to prevent leakage, where the gasket is pressed by the body part to increase pressurization away from the branch hole, and includes reinforcement surfaces and grooves to enhance sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect branch pipe to inflow pipe, then connection strength is improved, but assembly time and construction cost increase
Solution Approach 1:
A coupler is introduced as an intermediary component to connect the inflow pipe and branch pipe. The coupler includes a body part that surrounds the branch hole and a gasket part that prevents fluid leakage, eliminating the need for welding while ensuring strong and leak-proof connection.
2Productivity
If branch hole diameter is increased to increase flow rate, then fluid flow rate is improved, but fluid leakage occurs
Solution Approach 1:
The gasket part is designed with non-uniform thickness, being thicker at the end away from the branch hole and thinner near the branch hole. This local variation in quality provides enhanced sealing capability at the critical leakage-prone area while maintaining adequate flow rate through the larger branch hole diameter.
Solution Approach 2:
The degree of pressurization against the gasket part by the body part increases in a direction away from the branch hole. This parameter change in pressurization distribution ensures effective sealing even when the branch hole diameter is increased for higher flow rates.
3Ease of manufacture
If conventional T-pipe or welding method is used, then pipe connection is achieved, but number of parts and assembly complexity increase
Solution Approach 1:
The coupler merges multiple functions into a single integrated component: the body part provides structural connection and surrounds the branch hole, while the gasket part integrated into the coupler provides fluid leakage prevention. This consolidation reduces the number of separate parts compared to conventional T-pipe or welding methods.

AI summary
The present invention relates to a coupling assembly for pipe branching and, more specifically, to a coupling assembly for pipe branching, which: can reduce assembly man-hours; has a simplified structure and thus can reduce construction costs; and can effectively prevent leakage of a branch fluid even when the diameter of a branch hole formed through an inflow pipe is increased in order to enable the increase in the internal flow rate of a branch pipe through which a fluid is supplied to a sprinkler.
