Direct-Fit Vertical Gas Valve Layout to Cut Leakage Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas proportional valves for RVs require complex installation due to metal elbow pipes connecting the gas inlet, gas proportional valve, and burner, increasing the risk of gas leakage and costs.
Innovation Solution
A direct-fit vertical gas proportional valve integrating the gas shut-off and proportional control components within a single valve body, eliminating the need for separate pipes and reducing the risk of gas leakage by incorporating a channel for direct connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal elbow pipes are used to connect the gas inlet, gas proportional valve, and burner, then the gas proportional valve can be installed, but the installation becomes complicated and costly, and the risk of gas leakage increases
Solution Approach 1:
The patent merges the gas inlet, gas proportional valve, and burner connection into a single integrated valve body structure. The gas inlet is directly connected to the first valve chamber, which is connected to the second valve chamber, and finally to the gas outlet that connects to the burner. This eliminates the need for separate metal elbow pipes and multiple connection ports, thereby simplifying installation and reducing gas leakage risks.
2Ease of manufacture
If metal elbow pipes are used for connection, then the gas proportional valve can be assembled, but the cost increases and gas leakage risk increases
Solution Approach 1:
The patent combines multiple components into a single integrated valve body where the gas inlet, first valve chamber, second valve chamber, and gas outlet are all part of the same structure. This eliminates the need for separate metal elbow pipes and multiple connection points, thereby reducing manufacturing costs and minimizing gas leakage risks through fewer potential failure points.
