AI Technical Summary
Existing acid and alkali pipeline flange interfaces are prone to leakage. Manual inspection is time-consuming and labor-intensive, and it is difficult to detect even minor leaks in time, posing a safety hazard. Existing protective devices do not have early warning and detection functions.
Design a protective device for acid and alkali pipeline connection flanges, including first and second protective covers, with a leak detection box, strain sensor, audible and visual alarm and automatic controller inside. The strain sensor detects liquid leakage and triggers the audible and visual alarm for early warning. The automatic controller interlocks with the central control room to realize timely detection of the leak point.
It enables timely leak detection and early warning of acid and alkali pipeline flanges, reducing safety hazards and improving production safety.
