Multi-Outlet Valve Sealing Structure to Prevent Pipe Twisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-outlet valves experience fluid seepage and twisting of connected fluid pipes due to relative rotation, leading to potential deformation and leakage issues over time.
Innovation Solution
The improved multi-outlet valve structure features a valve housing with a control pivoting portion and lateral groove holes, a valve body with a valve core and control shaft, and an inlet connector with a valve body seat and conduit. This configuration includes ring-shaped elastic members to maintain fluid tightness and reduce friction, along with notches on the valve core and U-shaped fixing pins for enhanced stability and smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the valve core is rotated to control fluid discharge, then multiple outlet directions are achieved, but fluid seepage occurs between the valve core and valve housing
Solution Approach 1:
A flexible sealing ring is installed in a groove on the outer circumference of the valve core, allowing the sealing element to deform and adapt to the rotating motion while maintaining fluid tightness between the valve core and valve housing during rotation
2Ease of operation
If the drive shaft is rotated to operate the valve core, then fluid discharge control is achieved, but the connected fluid pipe becomes twisted and deformed
Solution Approach 1:
A universal joint mechanism is introduced as an intermediary between the drive shaft and the valve core, allowing rotational motion to be transmitted while accommodating angular misalignment and preventing twisting forces from being transmitted to the connected fluid pipe
3Adaptability or versatility
If the valve core rotates relative to the valve housing, then outlet selection is achieved, but friction and wear increase over time
Solution Approach 1:
The flexible sealing ring not only provides sealing but also reduces friction between the valve core and housing during rotation, decreasing wear and extending the service life of the moving parts while maintaining outlet selection capability

AI summary
This invention relates to a multi-outlet valve, and the valve includes a valve seat, a valve body, and an inlet connector. By the cooperation of the valve seat, the valve body, a fluid-tight anti-leakage effect of the valve core relative to the valve seat can be achieved. By the cooperation of the valve seat and the inlet connector, a twist of the inlet connector relative to a fluid pipe and adversely affecting the service life of the fluid pipe can be avoided during the process of connecting the fluid pipe so as to achieve good structural functionality and stability.
