Rotatable Valve Core Disk for Adjustable Gas Deflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valves for inflatable objects have complex structures and are inconvenient for users to deflate, as they require removal of the valve body from the valve seat.
Innovation Solution
A valve design featuring a rotatable valve core disk with one-way diaphragm and seal ring, allowing for adjustable passage and easy inflation/deflation by rotating the valve core disk to control gas flow, with a simple structure that seals in one direction to prevent gas leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve body is removably mounted within the valve seat with a one-way valve plate, then the valve can seal the gas passage during inflation, but the structure becomes complicated and it is inconvenient for users to deflate the inflatable object
Solution Approach 1:
The valve is divided into two main functional components: a removable valve body and a fixed valve seat. The valve body contains the one-way valve plate and can be easily detached from the valve seat, separating the sealing function (valve plate) from the structural housing (valve body and seat), thereby simplifying the overall structure while maintaining reliable sealing during inflation.
Solution Approach 2:
Instead of using a complex multi-component valve mechanism, the invention inverts the approach by using a simple one-way valve plate that automatically seals under pressure. The valve plate is designed to be pushed against the valve seat opening by internal gas pressure, creating a passive sealing mechanism that eliminates the need for additional sealing components or complex actuation mechanisms.
2Ease of manufacture
If the valve body is removably mounted within the valve seat, then the valve can be assembled easily, but it requires removal of the valve body for deflation which is inconvenient for users
Solution Approach 1:
The valve body is designed as a separate, removable component from the valve seat, allowing for easy assembly and disassembly during manufacturing. The valve body can be easily attached to and removed from the valve seat without special tools, maintaining ease of manufacture while enabling convenient deflation operations.
Solution Approach 2:
The valve design allows users to perform deflation themselves by simply removing the valve body from the valve seat and releasing the gas. The self-sealing one-way valve plate automatically prevents gas leakage when the valve body is attached, eliminating the need for additional sealing operations or complex user actions during both assembly and deflation processes.
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 valve allows for efficient inflation and deflation of inflatable objects by controlling gas flow direction, reducing the complexity of the structure and making the process more user-friendly, while maintaining a simple design.
Implementation Method 1
the one-way diaphragm is configured for sealing the through holes in one direction, so as to enable the valve core disk to seal the passage in one direction
Implementation Method 2
the seal ring is in interference fit with a side wall of the passage, so as to fill in a gap between the valve core disk and the side wall of the passage, and to enable the valve core disk to universally rotate with respect to the valve body
Implementation Method 3
the one-way valve plate abuts against the valve body due to that a gas pressure inside the inflatable object is greater than a pressure of outside atmosphere, thus closing the gas passage and preventing leakage of the gas inside

AI summary
Provided is a valve, relating to the mechanical equipment technical field, comprising a valve body (1) provided with a passage configured for allowing a fluid to pass through and a valve core disk (2) provided within the passage and rotatable relative to the valve body (1). The valve core disk (2) is provided with through holes (21) and has one side face provided with a one-way diaphragm (3) which is used for sealing the through holes (21) in one direction to enable the valve core disk (2) to seal the passage in one direction. Since the valve core disk (2) can rotate relative to the valve body (1), one-way-inflation and -deflation can be realized, and during deflation, the passage can be opened for deflation just by rotating the valve core disk (2). Users can adjust a deflating speed by rotating the valve core disk (2). The valve not only has a simple structure, but also is convenient for the user to deflate.
