Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to fire protection air tightness detection equipment. Background Art

[0002] Fire protection air tightness testing equipment is used to verify the air tightness of fire protection systems, pipelines, equipment, and sealing systems to ensure they are leak-free during actual use, thereby ensuring the proper operation and safety of the fire protection system. Air tightness testing is a crucial step in ensuring the effectiveness and safety of fire protection facilities, especially in environments requiring high pressure or toxic gases. Air tightness directly impacts the fire protection system's ability to operate reliably in emergencies. The design and installation of fire protection systems typically include fire extinguishing systems (such as automatic sprinkler systems), gas fire extinguishing systems (such as carbon dioxide, FM-200, and IG-541), and other related equipment. The operating principles and effectiveness of these systems are directly affected by the tightness of their pipelines, valves, and equipment. Leaks can lead to ineffective extinguishing agents, unstable system pressure, and even fire extinguishing failure, resulting in serious property damage and even life-threatening risks. Therefore, testing the air tightness of fire protection systems is not only a component of fire protection system quality control but also a key measure to ensure the proper operation of fire protection facilities in emergency situations such as fires.
