Double Action Float Valve Single Pipe Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current float valve systems require multiple lines and complex mechanisms for high-pressure applications, leading to increased costs and maintenance, and existing solutions fail to effectively manage both inflow and outflow through a single line without leaks.
Innovation Solution
A double action float valve design utilizing a single valve body connected to an inflow/outflow pipe with a heavy filling obturator and a light inverse float obturator, allowing for fluid control through a single pipe by adjusting the position of the float and obturators based on pressure differences between the pipe and tank, ensuring leak-free operation and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a basic direct-operated float valve is used, then the structure is simple, but it cannot stop flow at high pressures
Solution Approach 1:
The valve is divided into two separate obturators: a light obturator for normal operation and a heavy obturator for high-pressure applications. This segmentation allows each component to be optimized for its specific function, resolving the contradiction between simplicity and high-pressure reliability.
Solution Approach 2:
The system changes the weight parameter of the obturator based on pressure conditions. The light obturator is used during normal filling operations, while the heavy obturator is deployed when high pressure requires greater closing force, maintaining reliability across different pressure regimes without complicating the basic valve structure.
2Reliability
If pilot operated valves are used for high pressure, then flow control is reliable, but the valve becomes complex with multiple parts
Solution Approach 1:
The patent merges the functions of normal operation and high-pressure control into a single integrated valve body with two obturators. This eliminates the need for separate pilot valves and multiple control mechanisms, achieving high-pressure reliability while maintaining structural simplicity.
Solution Approach 2:
The valve body is designed to perform multiple functions: it handles both normal-pressure filling and high-pressure flow control using the same basic structure. The heavy obturator serves dual purposes by providing both structural support and high-pressure closing capability, reducing the need for additional specialized components.
3Reliability
If separate pipes are used for filling and discharge, then flow control is effective, but construction and maintenance costs increase
Solution Approach 1:
The valve is designed as a universal component that handles both filling and discharge operations through a single pipe connection. The same valve body and obturator mechanism effectively control flow in both directions, eliminating the need for separate piping systems and reducing construction and maintenance costs while maintaining effective flow control.
4Reliability
If more sophisticated float valves are used for larger tanks, then high pressure flow control is achieved, but cost increases
Solution Approach 1:
The obturator system is segmented into light and heavy variants that can be selected based on specific application requirements. This allows cost-effective deployment by using the simpler light obturator for normal applications while reserving the heavy obturator design only for high-pressure scenarios, rather than over-engineering all valves with complex multi-component systems.

Implementation Method 1
A heavy filling obturator (2) connected to a float (4) positioned outside the valve body (1) and within the tank (5)
Implementation Method 2
When the pressure of liquid from the inflow/outflow pipe (7) is greater than the pressure from the tank (5)... When the pressure from the tank (5), as measured at the outlet of the valve body (1) into the tank (5), is greater than the inflow pressure from the pipe (7)

AI summary
The double action float valve is connected to a single pipe and a tank and controls both the filling and discharge of the tank. The double action float valve utilizes a valve body, a heavy filling obturator positioned within the valve body, a light inverse obturator positioned within the heavy filling obturator, and a float connected to the heavy filling obturator. When the inflow pressure from the pipe is greater than the outflow pressure of the tank, the tank is filled until the float reaches a predetermined level. When the outflow pressure of the tank is greater than the inflow pressure, the double action float valve is automatically reconfigured to discharge the fluid from the tank into the pipe.
