Magnet-Controlled Two-Way Valve for Rapid Decompression

Solution Overview

Problem

Traditional two-way pressure relief valves have insufficient flow capacity for large containers, as the compression spring's increasing resistance limits the maximum flow rate, potentially leading to container damage during rapid decompression events.

Innovation Solution

A pressure relief valve design featuring a pair of magnets to control the actuation of a poppet for rapid gas outflow, combined with a compression spring for opposing flow direction, allowing higher flow rates due to the decreasing magnetic attraction with distance, and a return force member to ensure consistent closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a compression spring is used to control the poppet, then the valve can maintain sealing and control flow direction, but the spring's increasing resistance with opening distance limits the maximum flow rate

Engineering Contradiction:

Improveflow rateVSAvoidspring resistance

Core Design Contradiction:

ProductivityVSForce

Solution Approach 1:

The patent replaces the compression spring mechanism with a magnetic field mechanism. Magnets are positioned to create a magnetic force that holds the poppet closed, eliminating the need for a compression spring. This substitution allows the poppet to open fully without encountering increasing mechanical resistance, thereby achieving higher flow rates while maintaining sealing control through the magnetic field.

AI summary

Two-way pressure relief valves featuring dual poppets and magnets that allow very rapid flow. Such flow is accomplished by a valve housing enclosing a hollow interior portion containing a stationary member including a magnet and a first pressure-movable poppet disposed in sealing arrangement with the housing and including a second magnet. To provide flow in the other direction, a second moveable poppet disposed coaxially and in sealing arrangement with the first poppet and is coupled to a spring that extends from a first end of the second poppet to a support structure coupled to the second magnet.
