Separate Valve Seating for Backflow Control and Easy Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid management systems in pumps, particularly in delivery pumps, face challenges in preventing backflow and maintaining pressure while allowing fluid flow in the intended direction, which is not efficiently addressed by current valve technologies.
Innovation Solution
A valve array with a rotationally symmetrical or spherical closing body that moves translational to the fluid flow direction, utilizing a spring force and pressure differences to allow fluid flow in one direction while blocking it in the opposite direction, and featuring a valve seating body that can be easily assembled and centered without additional centering elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve array is designed to prevent backflow and maintain pressure, then fluid flow control is improved, but device complexity increases
Solution Approach 1:
The valve array is divided into multiple individual valves, each with its own closing body and valve seating. This segmentation allows each valve to independently control fluid flow in specific directions, improving backflow prevention while keeping each individual valve simple in structure.
Solution Approach 2:
A valve seating body is introduced as an intermediary component that provides a standardized interface between the closing bodies and the fluid channel housing. This mediator simplifies the overall design by centralizing the sealing function and eliminating the need for complex integrated valve structures.
2Ease of manufacture
If a valve seating body is integrated into the housing, then manufacturing is simplified, but assembly and centering become more difficult
Solution Approach 1:
The valve seating is separated from the housing as a distinct, removable component. This segmentation allows the valve seating body to be manufactured separately with precise centering features, then easily assembled into the housing without requiring complex integrated manufacturing processes.
Solution Approach 2:
The valve seating body is designed with self-centering features such as frictional fit connections and geometric constraints that automatically align it with the fluid channel during assembly. This self-service mechanism eliminates the need for additional centering elements or complex alignment procedures.
3Manufacturing precision
If additional centering elements are added to the valve seating, then positioning precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The valve seating body incorporates self-centering features directly into its structure, such as frictional fit connections with the housing and geometric constraints. These features automatically ensure precise positioning during assembly without requiring additional separate centering elements, thereby maintaining manufacturing precision while avoiding increased device complexity.

Function Achieved in This Case
The valve array effectively prevents backflow, maintains pressure, and allows fluid flow in the intended direction, while simplifying assembly and reducing manufacturing complexity by using a surmountable frictional or positive fit connection, ensuring a positionally secure connection under various operating conditions.
Implementation Method 1
The valve array also comprises a spring element which acts on the closing body and presses it against the valve seating
Implementation Method 2
utilizing a spring force and pressure differences to allow fluid flow in one direction while blocking it in the opposite direction

AI summary
A device including a valve array which is adapted to allow and block a fluid flow, wherein the valve array includes: a fluid channel; a valve seating; and a closing body, for example a rotationally symmetrical or spherical closing body, which is arranged in the fluid channel. The valve array is configured to allow a fluid flow when the closing body is lifted off the valve seating, and to prevent a fluid flow when the closing body rests against the valve seating. The valve seating is formed by a valve seating body, for example an annular valve seating body, which is arranged in or on the fluid channel.
