Modular Valve Tubular Element to Prevent Diaphragm Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic valve tubular elements are typically made as one monolithic piece, which complicates assembly, increases production costs, and makes it difficult to recover and reuse parts if the valve is unsuitable for use. Additionally, the fixing of these elements to the valve body can cause diaphragm deformation, particularly when screwed on, and does not facilitate easy assembly or prevent jamming of the core.
Innovation Solution
The tubular element is designed with two distinct bodies: a housing and a connection portion, which can be removably connected to form an assembly. This design allows for easier assembly, prevents diaphragm deformation by isolating rotational movements, and enables the reuse of individual bodies in other assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tubular element is made as one monolithic piece, then the manufacturing process is simplified, but the assembly complexity increases and part recovery becomes difficult
Solution Approach 1:
The tubular element is divided into two separate bodies: a housing body and a connection portion body. These can be manufactured independently and then assembled together, reducing manufacturing complexity while also enabling easier recovery and reuse of individual parts if needed.
2Reliability
If the tubular element is screwed onto the valve body, then hydraulic tightness is ensured, but the diaphragm element becomes deformed
Solution Approach 1:
By separating the connection portion from the housing body, the rotational screwing motion is isolated to the connection portion and does not transmit to the housing or diaphragm element, preventing deformation while maintaining hydraulic tightness through the threaded connection.
Solution Approach 2:
The connection portion acts as an intermediary between the valve body and the housing, absorbing the rotational movement during assembly and preventing it from being transmitted to the diaphragm element, thus protecting it from deformation.
3Productivity
If the tubular element is made as one monolithic piece, then production costs are reduced, but the number of parts increases and assembly time increases
Solution Approach 1:
The tubular element is segmented into a housing body and connection portion body that can be manufactured separately and independently, reducing production costs. The housing body can be pre-assembled with the core and diaphragm element before final assembly with the connection portion, reducing overall assembly time.
4Ease of repair
If the tubular element is designed for easy disassembly, then part recovery is facilitated, but the fixing reliability may be compromised
Solution Approach 1:
The separable design with distinct housing and connection portion bodies allows easy disassembly for part recovery while maintaining reliable fixing through the threaded connection interface. The standardized threading ensures both ease of assembly/disassembly and reliable hydraulic sealing.

AI summary
Tubular element (3) for electromagnetic valves adapted to be assembled to a valve body comprised in an electromagnetic valve. The tubular element comprises: a housing (4), adapted to internally receive a core and allow it to slide therein for switching said electromagnetic valve; and a connection portion (5) adapted to be removably fixed to said valve body for assembling the tubular element (3) to said valve body. Said housing (4) having a body (40) which is separate from and independent of said connection portion (5), which in turn has a body (50) of its own. Said body (40) of said housing (4) being connectable, in a removable manner, to said body (50) of the connection portion (5), thereby forming an assembly.
