Solution Overview
Problem
Current methods for testing the tightness of fluid storage tank sealing systems and pipe connection systems pose risks of leakage and pollution, requiring large quantities of test fluid and incurring additional costs, especially in large installations.
Innovation Solution
A device and method utilizing an annular pressurization chamber with a pressurization system and pressure measuring system, isolated by sealing elements such as O-rings, to test tightness without filling the entire system with test fluid, reducing the risk of leakage and pollution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire system is filled with pressurized test fluid to test leak-tightness, then the seal can be tested, but the risk of leakage and pollution increases and large quantities of test fluid are required
Solution Approach 1:
The invention divides the testing system into two separate chambers: a pressurization chamber for holding pressurized test fluid and a storage chamber for the process fluid. The seal being tested separates these two chambers. This segmentation allows testing to be performed on a localized portion of the system rather than requiring pressurization of the entire system, thereby reducing pollution risk while maintaining testing accuracy.
Solution Approach 2:
The seal acts as an intermediary element between the pressurization chamber and the storage chamber. By pressurizing only the pressurization chamber and observing pressure maintenance, the seal's integrity can be tested without introducing large volumes of test fluid into the storage chamber, thus reducing the harmful effects of potential leakage and pollution.
2Reliability
If the entire system is filled with pressurized test fluid to test leak-tightness, then the seal can be tested, but the quantity of test fluid required increases significantly
Solution Approach 1:
The testing apparatus is segmented into a pressurization chamber and a storage chamber. Only the pressurization chamber needs to be filled with test fluid for testing purposes, rather than the entire system. This dramatically reduces the quantity of test fluid required while maintaining the ability to accurately test seal integrity through pressure monitoring.
3Ease of operation
If the cover is drilled to fit a valve for pressurization, then the system can be tested, but additional leakage risk is introduced
Solution Approach 1:
The invention extracts the pressurization function from the cover assembly by providing a dedicated pressurization chamber with integrated pressurization means. This eliminates the need to drill holes in the cover for valve installation, thereby removing the additional leakage risk that drilling introduces while maintaining full pressurization capability for testing.
