Multi-Outlet Valve Sealing Structure to Prevent Leakage and Pipe Twisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-outlet valves suffer from fluid leakage and twisting of fluid pipes due to the deformation caused by the rotation of the valve core, leading to reduced service life.
Innovation Solution
The multi-outlet valve design incorporates a valve housing with a valve body that includes a valve core with notches to reduce friction, a U-shaped fixing pin for stability, and elastic members to ensure fluid-tight connections, along with anti-leakage rings to prevent deformation under pressure, enhancing structural stability and multiple outlet options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the valve core is rotated to control fluid discharge in multiple directions, then the multi-outlet function is achieved, but fluid leakage occurs between the valve core and valve housing
Solution Approach 1:
A flexible sealing ring is installed in the sealing cavity of the valve housing, which can elastically deform to maintain continuous contact with the valve core surface during rotation, ensuring fluid-tight sealing while allowing multi-directional fluid discharge
2Adaptability or versatility
If the valve core rotates to select multiple outlet directions, then fluid distribution flexibility is improved, but the fluid pipe connected to the valve body inlet becomes twisted and deformed
Solution Approach 1:
The fluid pipe connection is extracted from the rotating valve core assembly and fixed to the stationary valve housing body. The valve core rotates within the housing without rotating the fluid pipe connection, thereby maintaining pipe stability while achieving multi-directional fluid discharge control
3Strength
If the valve core and valve housing have large contact area for structural stability, then mechanical strength is improved, but friction increases and rotation smoothness deteriorates
Solution Approach 1:
A flexible sealing ring provides the necessary sealing function with minimal contact pressure, avoiding excessive friction while maintaining structural integrity through the elastic deformation capability of the sealing material
