Exhaust Gas Measuring Point System Double Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust systems with boiler connection pieces and measuring point systems face safety issues due to leaks in the plug, leading to dangerous exhaust gas concentrations in installation rooms, as exhaust gas can escape into the environment.
Innovation Solution
A measuring point system with a closure element that extends into both the outer and inner line component measurement openings, providing a double sealing mechanism to prevent exhaust gas from escaping into the environment, and featuring an elongated body with a sealing lip and locking mechanism for secure attachment and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single plug seals the measuring port, then the structure is simple, but exhaust gas can escape into the installation room causing dangerous concentrations
Solution Approach 1:
The sealing function is divided into two independent parts: an inner seal element sealing the inner pipe component measuring opening, and an outer seal element sealing the outer pipe component measuring opening. This segmentation ensures that if one seal fails, the other still prevents exhaust gas escape, thereby improving reliability without requiring a complex integrated sealing mechanism.
Solution Approach 2:
The design incorporates a redundant sealing mechanism where the outer seal element provides a backup sealing function. This beforehand cushioning ensures that even if the inner seal element becomes leaky, the exhaust gas cannot escape into the installation room, as the outer seal element prevents the escape path.
2Ease of operation
If the measuring port is open for measurement, then measurement access is provided, but exhaust gas can escape into the environment
Solution Approach 1:
The measuring port system is segmented into inner and outer sealing zones. The inner seal element can be opened for measurement access while the outer seal element remains closed, providing a controlled opening that allows measurement operations without compromising the overall sealing integrity of the system.
Solution Approach 2:
The outer seal element acts as an intermediary barrier between the inner measuring port and the external environment. When the inner seal is opened for measurement, the outer seal element maintains the sealing function, mediating between the need for measurement access and the requirement to prevent exhaust gas escape.
3Reliability
If a leak occurs in the plug, then exhaust gas escapes into the installation room, but detecting and restoring tightness is difficult
Solution Approach 1:
The sealing system is segmented into independently replaceable inner and outer seal elements. If a leak occurs, the specific faulty seal element can be identified and replaced without affecting the other sealing component, making repair simpler and more straightforward compared to replacing an integrated sealing system.
Solution Approach 2:
The seal elements are designed as disposable components that can be easily removed and replaced. When a seal element becomes leaky, it is discarded and replaced with a new one, while the remaining functional seal element is recovered and retained in the system, simplifying the repair process.
