Split Electric Valve Body for Easier Sensor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement process of a first sensing device in an electric valve is cumbersome due to the need to open a housing and remove the electric control board to access the sensing device for parameter-setting or maintenance.
Innovation Solution
The electric valve is designed with a first valve body and a second valve body formed separately, allowing the second valve body to be connected to a housing independently, with the sensing device mounted in a mounting chamber of the second valve body, facilitating easy removal and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sensing device is integrated into the housing with the electric control board, then the overall structure is compact, but the replacement process becomes cumbersome requiring disassembly of the housing and removal of the control board
Solution Approach 1:
The valve body is divided into a first valve body and a second valve body that can be separated from each other. The sensing device is mounted on the second valve body, which can be independently removed from the housing. This segmentation allows the sensing device to be accessed and replaced without disassembling the entire housing or removing the electric control board, thus resolving the contradiction between structural integration and ease of repair.
2Reliability
If the sensing device is accessible only after opening the housing, then the housing provides complete protection, but maintenance time and operational downtime increase
Solution Approach 1:
By segmenting the valve body into separable first and second valve bodies, the invention enables independent access to the sensing device mounted on the second valve body. This allows maintenance personnel to quickly remove and replace the sensing device without time-consuming disassembly of the entire housing, significantly reducing maintenance time while maintaining protective coverage through the first valve body.
Solution Approach 2:
The second valve body with the mounted sensing device can be extracted from the housing as an independent unit. This extraction capability allows the sensing device to be accessed, removed, and replaced quickly without affecting the housing's protective function, thus reducing maintenance time while preserving reliability.
3Ease of manufacture
If the valve body is formed as a single integrated piece, then manufacturing is simpler, but the sensing device cannot be easily accessed for parameter-setting or maintenance
Solution Approach 1:
The valve body is segmented into a first valve body and a second valve body that can be separately manufactured and then assembled. The sensing device is mounted on the second valve body, which can be independently accessed by separating it from the first valve body. This segmentation maintains manufacturing simplicity for each individual component while enabling easy access to the sensing device for parameter-setting and maintenance.
