Electromagnetic Valve Assembly With Integrated Spring Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic valves have complex structures that hinder quick assembly with air conditioning pipelines, involve complicated assembly processes due to integrated springs, and suffer from unstable limiting members that can move during operation, leading to increased manufacturing costs and reduced efficiency.
Innovation Solution
The electromagnetic valve incorporates a limiting portion integrated with the valve body to stabilize the elastic member, preventing offsetting and side bending, and includes detachable connections for improved assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional limiting member is provided to limit the spring, then the spring positioning is improved, but the assembly steps increase and assembly efficiency decreases
Solution Approach 1:
The limiting function is merged into the valve body structure itself. The limiting portion is formed as an integral part of the valve body, eliminating the need for separate limiting members and reducing assembly complexity while maintaining spring positioning stability.
Solution Approach 2:
The valve body provides its own limiting function through the integrated limiting portion, eliminating the need for additional components. The structure serves itself by incorporating the limiting function directly into the main body, reducing assembly steps while ensuring reliable spring positioning.
2Device complexity
If the spring is integrated with the valve body in a riveting form, then the assembly process is simplified, but the processing difficulty and manufacturing costs increase
Solution Approach 1:
The spring assembly is segmented from the valve body, allowing the spring to be independently installed and positioned. This segmentation enables simpler assembly processes while avoiding the need for complex riveting operations, reducing manufacturing difficulty without compromising structural integrity.
3Device complexity
If no limiting portion is provided, then the assembly process is simpler, but the elastic member may offset or side bend causing poor sealing effect
Solution Approach 1:
The limiting function is merged into the valve body structure. The limiting portion is formed as an integral part of the valve body, providing reliable positioning and sealing assurance without adding complex assembly steps or separate components.
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
The solution ensures linear movement of the elastic member, reduces assembly steps, and enhances overall assembly efficiency while maintaining stable limiting effects, thus improving manufacturing costs and ease of connection with other components.
Implementation Method 1
a spring is provided between a bottom of a valve body and a plugging assembly, and the plugging assembly is driven by an elastic force of the spring to open the valve port
Implementation Method 2
a friction force can be applied on the other end of the first elastic member by the limiting portion, which is conducive to preventing the other end of the first elastic member from entangling with a middle part of the first elastic member during reciprocating compression and extension

AI summary
An electromagnetic valve and an electromagnetic valve assembly are provided. The electromagnetic valve includes a first elastic member. An end of the first mounting cavity proximal to the valve port is provided with a limiting portion integrated with the valve body, the first elastic member is sleeved on the plugging assembly. One end of the first elastic member abuts against the plugging assembly, the other end of the first elastic member abuts against the valve body, and an outer surface of the other end of the first elastic member abuts against the limiting portion.
