AI Technical Summary
Existing technologies lack intuitive means to verify the sealing performance of water-blocking devices. The testing process is complex and the results are difficult to perceive. It is impossible to simulate the performance under different pressures, which affects product promotion.
Design a test model for a water-blocking device in an insulated pipe jacket for demonstrating its sealing performance. The model includes a working pipe and an outer pipe. Pressure changes are monitored using a pressure gauge to simulate the structure of a heating pipeline. Polyurethane insulation material is used to fill the joints to ensure sealing performance and to eliminate interference from factors other than the water-blocking device.
It enables rapid and objective assessment of the sealing effect of water blockers, improves testing efficiency and convenience, provides high reference value for results, and closely matches the testing scenarios with actual engineering practice, eliminating the influence of non-sealing factors.
