Plastic Valve Flange Reinforcement to Prevent Pipe Connection Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic valves experience distortion when connected or attached to pipes, leading to twisting and potential leaks, especially when flange members are formed at the ends.
Innovation Solution
Incorporating a metal member with protrusions into the flange member of the plastic valve, which is formed through insert molding, to minimize distortion forces and prevent twisting during connection processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plastic valve with flange member is used for connection, then ease of operation is improved, but distortion and twisting occur during connection
Solution Approach 1:
The patent applies composite materials by combining a metal member (reinforcement) with a plastic flange member. The metal member is embedded within the plastic flange member to create a composite structure that leverages the strength of metal and the ease of molding of plastic, preventing distortion while maintaining connection ease
Solution Approach 2:
The patent applies local quality by strategically placing the metal member only in specific regions where distortion occurs during connection, rather than making the entire flange member metal. This localized reinforcement prevents twisting at critical areas while maintaining the overall plastic construction
2Adaptability or versatility
If flange member is formed at end of plastic valve, then adaptability is improved, but distortion force increases during connection
Solution Approach 1:
The patent uses composite materials by embedding a metal member within the plastic flange member to create a structure that maintains adaptability for various connections while resisting distortion forces through the reinforced composite construction
3Strength
If metal member is added to flange member, then strength is improved, but device complexity increases
Solution Approach 1:
The patent applies the nesting principle by placing the metal member inside the plastic flange member, creating a nested structure where one component is embedded within another. This increases strength while maintaining a relatively simple overall structure that can be manufactured as an integrated unit
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The metal member with protrusions effectively prevents distortion and twisting, ensuring secure connections and preventing leaks when pipes are connected, maintaining the integrity of the plastic valve and ensuring gas or solution flow is uninterrupted.
Implementation Method 1
a metal member having a protrusion is formed in a flange member, and so distortion may not be generated to the plastic valve

AI summary
A plastic valve for preventing distortion is disclosed. The plastic valve comprises a connection member (210) made up of plastic and a flange member (212) made up of plastic and formed at an end part of the connection member. Here, a metal member (220) is formed in the flange member, and the metal member includes a body and at least one protrusion (216) projected from the body in a direction of an end of the flange member.
