Check Valve Poppet Hole Layout for Simpler Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for check valve poppets is labor-intensive and costly due to the need for specialized tooling to form complex beveled surfaces, making it inefficient and expensive.
Innovation Solution
A poppet design featuring a base with linearly formed holes through a flat surface, extending to an internal cavity, and a shaft with a sealing head, allowing for simplified and cost-effective production without complex tooling, using a forming tool like a drill to create the holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specialized machining is used to form holes through the beveled neck, then the holes can be formed with proper orientation and shape, but the manufacturing process becomes time-consuming and labor-intensive
Solution Approach 1:
Instead of forming holes through the complex beveled exterior surface of the neck, the patent inverts the approach by forming holes through the simpler interior surface of the cavity. This reversal allows standard drilling equipment to be used on a flat, accessible surface rather than requiring specialized tooling for the beveled exterior, thereby improving manufacturing efficiency while maintaining hole precision
Solution Approach 2:
The patent replaces expensive, specialized machining tooling with simple, inexpensive standard drill bits. By forming holes through the cavity interior rather than the beveled neck exterior, the invention eliminates the need for costly custom fixtures and specialized equipment, using instead common, readily available drilling tools that can be easily replaced or reused
2Reliability
If complex beveled neck geometry is used, then proper fluid flow control is achieved, but specialized tooling and costly manufacturing processes are required
Solution Approach 1:
The patent separates the fluid flow control function from the complex beveled geometry by placing the flow control holes in the base rather than in the neck. The neck's beveled shape can remain simple while the base contains the precisely positioned holes that control fluid flow, dividing the complex requirements into simpler, independently manufacturable components
Solution Approach 2:
The base acts as an intermediary element that mediates between the simple neck structure and the fluid flow control requirements. By forming holes in the base rather than the beveled neck, the invention uses the base as a中介 structure that simplifies manufacturing while still achieving the necessary fluid flow control through its hole configuration

AI summary
A poppet of a check valve includes a base, a shaft extending from the base, and a sealing head coupled to the shaft and extended away from the base by the shaft. A flow channel is defined between the base, the shaft, and the sealing head. The base includes a plurality of holes.
