Valve Vent Sensor Mounting Without Flow Cross-Section Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valves face difficulties in mounting and detaching sensor devices due to their inaccessible location within the valve housing, which complicates data acquisition for fluid properties like pressure, temperature, and flow rate.
Innovation Solution
The integration of a sensor device in a previously unused fluid opening of the valve housing allows for easy access and mounting/detaching, utilizing this opening as both a data acquisition point and a seal, without reducing the fluid flow cross-section, and incorporating a separate fluid connection plate for electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor devices are integrated in cavities within the valve housing, then data acquisition capability is improved, but mounting and detaching becomes difficult
Solution Approach 1:
The sensor device is extracted from the traditional cavity integration approach and repositioned to protrude through the valve seat plate. This allows the sensor to be accessible from the outside of the valve housing while still being integrated into the valve structure, enabling easy mounting and detaching while maintaining data acquisition capability.
2Measurement precision
If a separate installation space is provided for sensor devices, then data acquisition capability is improved, but device complexity and sealing requirements increase
Solution Approach 1:
The valve seat plate is designed to serve multiple functions: it acts as the structural component for fluid control with valve seats, and simultaneously serves as the mounting base for the sensor device. The fluid connection plate with its receiving opening provides both fluid connection functionality and sensor accommodation, eliminating the need for separate installation spaces and reducing sealing requirements.
3Ease of operation
If the sensor device protrudes through the valve seat plate, then accessibility for mounting is improved, but the inner wall space is reduced
Solution Approach 1:
Instead of reducing the inner wall space by creating steps or recesses in the housing, the sensor device is positioned to protrude through the valve seat plate in a direction perpendicular to the fluid flow path. This dimensional approach allows the sensor to be accessible from the outside while the housing inner wall remains smooth and continuous, maintaining the full fluid flow cross-section.

AI summary
A valve has a housing which has at least two fluid openings, through which fluid can flow, and a further opening, at least one valve seat which is assigned to one of the fluid openings, and at least one closure member which is adjustable to release and/or close the at least one valve seat, the at least one valve seat which adjoins a cavity through which fluid can flow being formed on a housing part. The valve includes a sensor device which closes the opening in a fluid-tight manner and can acquire data about the fluid is arranged in the further opening. A valve island is furthermore described.
