Integrated Safety Valve for Manual and Automatic Pressure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and space requirements of pressure loops in gaseous and hydraulic pressure devices are increased due to the need for both manual and automatic safety valves to manage pressure beyond a predetermined level, as existing solutions require separate valves for each operation mode.
Innovation Solution
A safety valve design that incorporates a single valve core for both manual and automatic pressure release operations, utilizing a resilient member to bias the valve core to a closed position and a control mechanism for manual or automatic actuation, allowing fluid to flow between the inlet and outlet or releasing port based on pressure thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate manual and automatic safety valves are provided in the pressure loop, then pressure release reliability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines manual and automatic safety valve functions into a single integrated valve body. The valve core can be actuated either automatically by a resilient member responding to pressure differential or manually through a button, eliminating the need for separate manual and automatic safety valves while maintaining dual functionality.
Solution Approach 2:
The single safety valve is designed to perform multiple functions: automatic pressure release through the resilient member mechanism and manual pressure release through the button actuation. This multi-functional design allows one valve to replace what would traditionally require two separate valves, reducing overall system complexity.
2Reliability
If separate manual and automatic safety valves are provided in the pressure loop, then pressure release reliability is improved, but space requirements increase
Solution Approach 1:
The patent merges manual and automatic safety valve functions into a single compact valve assembly. By integrating both actuation mechanisms (resilient member for automatic, button for manual) within one valve body, the space required is reduced compared to installing two separate valves, directly addressing the space constraint issue.
3Device complexity
If a single valve core is used for both manual and automatic operation, then device complexity is reduced, but control precision may be compromised
Solution Approach 1:
The valve core is designed with dynamic actuation capabilities, allowing it to respond differently based on the actuation method. The resilient member provides automatic dynamic response to pressure changes, while the button provides manual static control. This dynamic design enables a single valve core to accommodate both operation modes with appropriate control characteristics for each.
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
This design achieves a more compact structure by enabling both manual and automatic pressure release using the same valve core, ensuring efficient pressure management without the need for additional space-consuming components.
Implementation Method 1
The valve core comprises a resilient member which biases the valve core to the close position
Implementation Method 2
the fluid flowing through the valve body acts upon the valve core such that the valve core enters into the open position from the close position when the pressure of the fluid is larger than the biasing force of the elastic member

AI summary
The present application relates to a safety valve, in particular a safety valve which can be released by manual operation and automatic operation. The safety valve comprising: valve body having an inlet, an outlet and a releasing port; and valve core being movable within the valve body between a close position in which the inlet communicates with the outlet and an open position in which the inlet communicates with the releasing port, the valve core comprises a resilient member which biases the valve core to the close position; wherein the position of the valve core can be manually or automatically controlled such that the valve core is able to switch between the close position and the open position, fluid flows from the inlet to the outlet in the close position and flows from the inlet to the releasing port in the open position.
