Gas Fitting Throttle Device with Integrated Pressure Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas fittings require multiple pressure measuring points to ensure accurate burner pressure measurement, leading to complexity and potential for incorrect measurements due to the need for additional measuring points outside the gas fitting.
Innovation Solution
Positioning the nozzle within a throttle device before the measuring point allows burner pressure measurement at the gas valve train outlet, eliminating the need for additional measuring points and reducing complexity by integrating the throttle device with a holder and removal pin for easy installation and flow optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple pressure measuring points are used to ensure accurate burner pressure measurement, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the throttle device with the holder into a single integrated assembly that can be installed as one unit. The holder is designed with a recess that receives the throttle device, and both components are installed together through the outlet connection, reducing the number of separate installation steps and components while maintaining measurement accuracy.
Solution Approach 2:
The outlet connection serves multiple functions: it acts as both the gas outlet connection and the installation path for the holder with throttle device. The holder is designed to be installed through the outlet connection without requiring separate mounting operations, making the outlet connection a multi-functional element that reduces overall device complexity.
2Measurement precision
If additional measuring points are added outside the gas fitting, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The holder and throttle device are merged into a single installable unit that passes through the outlet connection. This integration means that what would otherwise require separate installation steps (throttle device mounting, holder mounting, sealing) is now a single operation, improving ease of operation while maintaining the ability to measure burner pressure accurately through the integrated structure.
3Reliability
If the throttle device is mounted with additional components, then reliability is improved, but device complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: the gas fitting, the outlet connection, the holder, and the throttle device. Each module performs a specific function and can be analyzed independently. The holder acts as an intermediary module that connects the throttle device to the gas fitting through the outlet connection, providing a reliable sealed connection while keeping each component relatively simple in structure.
Solution Approach 2:
The holder serves as an intermediary component between the throttle device and the gas fitting. It provides the sealing function through the seal element and provides the mounting structure for the throttle device, while allowing the throttle device to be installed and removed without disturbing the gas fitting itself. This intermediary role improves reliability by providing a dedicated sealing and mounting interface.
