Electromagnetic Valve Flap Assembly for Precise Flow and Backflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional regulating valves face limitations in precision regulation and are prone to backflow issues due to their single valve flap design, which restricts effective control of flow and pressure parameters.
Innovation Solution
An electromagnetic regulating valve with a check function is developed, featuring a valve flap group structure, an annular permanent magnet, annular spring, and an orifice plate, allowing for precise control of flow and prevention of backflow through an external control circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single valve flap is used in a conventional regulating valve, then the structure is simple, but the regulation precision is limited and backflow cannot be prevented
Solution Approach 1:
The single valve flap is divided into multiple valve flaps (first valve flap, second valve flap, third valve flap) arranged in series. Each valve flap can be independently controlled to different opening degrees, enabling precise flow regulation and preventing backflow through the coordinated action of multiple flaps.
Solution Approach 2:
The valve flaps are equipped with electromagnetic coils that enable dynamic, independent control of each flap's opening degree. This dynamic control system allows precise adjustment of flow parameters and rapid response to prevent backflow, transforming the static single-flap design into a dynamically controllable multi-flap system.
2Reliability
If a conventional regulating valve is used, then the valve body structure is simple, but it cannot prevent backflow and may cause adverse consequences
Solution Approach 1:
The valve body is divided into multiple functional sections including a valve body, valve flap group base, and electromagnetic coil assembly. This segmentation allows each component to perform its specific function independently, with the multi-flap structure providing backflow prevention while maintaining modular simplicity in the overall valve body design.
Solution Approach 2:
The valve flaps serve multiple functions: they regulate flow by adjusting opening degrees and simultaneously prevent backflow by closing in reverse flow conditions. The electromagnetic coils provide both positioning control and rapid closure capability, making the system multi-functional without requiring separate dedicated components for each function.

AI summary
The present disclosure discloses an electromagnetic regulating valve with a check function. The valve may effectively regulate the flow in a valve body. Due to different lengths and taper angles of a valve flap group, the flow can be regulated more finely, and a medium can be prevented from backflow by a check function when necessary. Meanwhile, a mesh structure of bases of valve flaps can effectively reduce the instability of flow field motion so as to achieve an effect of rectifying.
