Miniature Valve Segmented Chamber Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional miniature valves have complex liquid chambers with large dead areas, result in violent liquid fluctuations during switching, and are limited by solenoid drive and poor liquid pressure endurance, restricting their application scope.
Innovation Solution
A miniature valve design featuring a valve body with a supporting device, valve seat, rocker, and elastic valve film, which divides the chamber into liquid and installing chambers, allowing for streamlined flow channels and reduced liquid fluctuation through elastic distortion, and can be driven by both solenoid and cylinder devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional liquid chamber design is used, then valve structure is simple, but dead areas remain large and liquid flow is blocked
Solution Approach 1:
The liquid chamber is segmented into multiple zones by partition walls that extend from the valve seat. These partition walls divide the chamber into a first liquid chamber communicating with the first channel and a second liquid chamber communicating with the second channel, eliminating dead areas and ensuring complete liquid flow through the valve.
2Ease of operation
If valve film switching is used, then channel direction is changed, but violent liquid fluctuations occur in pipelines
Solution Approach 1:
An elastic valve film is employed as the switching element instead of rigid components. The valve film can be flexibly deformed to open or close channels, providing smooth transitions that minimize liquid fluctuations and violent pressure changes in the pipeline during channel switching operations.
3Device complexity
If solenoid drive only is used, then valve structure is simple, but application scope is limited and liquid pressure endurance is poor
Solution Approach 1:
The valve is designed with a universal driving interface that can accommodate multiple types of actuators including solenoids, cylinders, and other driving devices. This multi-functionality allows the same valve body and valve film mechanism to be used across different applications with varying pressure and control requirements, significantly expanding the application scope.

AI summary
The present invention relates to a miniature valve, which includes a valve body comprising an inflow channel, an outflow channel and a liquid chamber, and a close assembly comprising a driver, a rocker and a valve film. The close assembly connects to the valve body and is configured to selectively close the inflow channel and the outflow channel. The rocker can be driven by the driver to move, so that the movement thereof acts on the valve film and makes the valve film selectively close the channel. The rocker and the valve film are separate components. The valve film, an elastic film locating in the liquid chamber, has a size configured to cover the inflow channel and the outflow channel. The miniature valve according to the present invention doesn't have interior dead area and has a slight effect on liquid fluctuation when switching channels.
