The implementation of a hydraulic servo-actuated valve with a composite actuating duct that eliminates the need for connection pipes by directly connecting operative members to the valve body and lid through flanged couplings, enhancing assembly speed, robustness, and ease of cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection pipes are used to connect operative members to the valve body and lid, then the valve can be operated, but the assembly becomes complex and time-consuming
Solution Approach 1:
The patent merges the connection pipes with the valve body and lid by integrating the inlet and outlet ducts directly into these components. The operative members are connected directly to the valve body and lid without external pipes, eliminating the need for separate connection components and simplifying the overall assembly structure.
Solution Approach 2:
The valve body and lid are designed to serve multiple functions: they provide structural support, contain the actuating chamber, and directly connect to operative members through integrated ducts. This multi-functionality eliminates the need for separate connection pipes and reduces assembly complexity.
2Ease of manufacture
If connection pipes are used to connect operative members, then the valve can be assembled, but assembly time increases significantly
Solution Approach 1:
The connection ducts are merged with the valve body and lid structures, allowing operative members to be connected directly during the valve assembly process without requiring separate pipe installation steps. This integration significantly reduces assembly time and simplifies the manufacturing process.
Solution Approach 2:
The inlet and outlet ducts are pre-integrated into the valve body and lid during manufacturing, so that when the valve is assembled, the connection paths are already in place. This preliminary integration eliminates the need for time-consuming pipe connection operations during final assembly.
3Ease of manufacture
If traditional pipes are used for connection, then the valve can be constructed, but the structure becomes fragile and susceptible to damage
Solution Approach 1:
The connection ducts are merged with the robust valve body and lid structures, eliminating the need for separate, vulnerable pipes. The integrated ducts benefit from the structural strength of the valve components, making the overall construction more resistant to damage from rodents, animals, and human error.
Solution Approach 2:
The vulnerable connection pipes are extracted from the system and replaced with integrated ducts formed as part of the valve body and lid. This removal of separate pipe components eliminates the fragility and susceptibility to damage that characterized the previous design.
4Ease of operation
If connection pipes are used, then the valve can function, but cleaning and maintenance become difficult due to obstructions
Solution Approach 1:
The connection ducts are merged with the valve body and lid, creating open, accessible pathways that are integrated into the main valve structure. This integration allows for easier inspection and cleaning compared to separate, enclosed pipes, as the ducts can be accessed directly through the valve components.
Solution Approach 2:
The valve is segmented into modular components (valve body, lid, operative members) with integrated ducts that can be accessed and cleaned independently. This segmentation allows maintenance personnel to access and clean the connection pathways without disassembling the entire valve, facilitating easier maintenance.

Function Achieved in This Case
This design simplifies and accelerates assembly, increases the valve's robustness, and facilitates cleaning by eliminating the fragility and obstruction issues associated with traditional pipes, resulting in a more reliable and efficient operation.
Implementation Method 1
an elastically deformable membrane made of rubbery material, whose edge is tightened between the edge of the main opening and the edge of a lid
Implementation Method 2
The liquid entering the actuating chamber from the inlet duct generates a pressure in the actuating chamber that thrusts the actuator to a completely lowered position
