Flow Meter Valve Anchor Member Prevents Junction Fractures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flow meter regulation valve fastening structure is prone to fractures when the regulation valve is coupled with the holder and a pipe due to excessive turning forces, leading to reduced lifespan and increased manufacturing costs.
Innovation Solution
A flow meter regulation valve fastening structure that includes a holder with a frame edge coupled to a regulation valve featuring a screw head with a pipe connection screw hole and an anchor member with a coupling plate and detent plates to prevent junction fractures, where the anchor member's coupling plate couples with the screw head and detent plates butt the holder's frame edge to retain and prevent turning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the regulation valve is coupled with the holder using a single connection rib and fastening portion, then the device complexity is reduced, but the strength of the junction is insufficient leading to fractures under excessive turning forces
Solution Approach 1:
The connection rib is divided into multiple segments (first connection rib, second connection rib, third connection rib) that extend in different directions from the screw hole. Each segment connects to a separate fastening portion, distributing the mechanical stress across multiple locations rather than concentrating it at a single point. This segmentation allows the structure to handle excessive turning forces without fracturing while maintaining relatively simple overall design.
Solution Approach 2:
Multiple fastening portions are combined with a single screw hole to create a unified fastening system. The anchor member integrates the coupling plate that attaches to the screw head and the anchor plate with multiple fastening portions, merging multiple fastening functions into one component that works together to prevent junction fractures.
2Ease of manufacture
If the holder is made of acrylic material, then the manufacturing cost is reduced and ease of manufacture is improved, but the reliability of the junction is reduced making it prone to fractures
Solution Approach 1:
The anchor member is pre-installed on the regulation valve before the final assembly with the holder. The coupling plate is coupled to the screw head in advance, and the detent plates are positioned to engage with the frame edge. This preliminary action ensures that the fastening structure is already in place to prevent fractures during subsequent pipe connection operations, improving reliability without changing the acrylic material.
Solution Approach 2:
The multiple connection ribs and fastening portions are designed to distribute and cushion the excessive turning forces before they can concentrate at a single weak point in the acrylic holder. The detent plates engaging with the frame edge provide additional cushioning support, preventing the junction from fracturing under operational stress while maintaining the use of acrylic material.

AI summary
A flow meter regulation valve fastening structure includes a holder with one side coupled with a regulation valve by screwing. The regulation valve has a regulation shaft with a flange and a screw head located at an upper side. The screw head is coupled with an anchor member. The anchor member has a coupling plate at one end coupled on the screw head and an anchor plate at another end with two detent plates extended downwards from two sides to butt two sides of the frame edge of the holder for retaining. Thereby when the regulation valve is coupled with the holder and a pipe, the junction of the regulation valve and the holder can be prevented from generating fractures due to excessive turning forces.
