Description

Technical Field

[0001] The utility model relates to the technical field of production and filling of fire-fighting equipment, in particular to an automatic filling and pressurizing device for perfluorohexanone fire extinguishing agent. Background Art

[0002] At present, common gas fire extinguishing agents in China, such as heptafluoropropane fire extinguishing agent, are gaseous at room temperature and pressure. Fire extinguishing agent manufacturers use large storage tanks to transport them in liquid form after pressurization. Gas fire extinguishing equipment manufacturers can fill fire extinguishing agents through conventional booster pumps or nitrogen pressurization. The existing heptafluoropropane fire extinguishing agent filling equipment is manually operated and records production data, and cannot be automatically filled, and cannot automatically generate filling record reports. Perfluorohexanone fire extinguishing agent is transported in iron barrels without pressure. The barrel wall is relatively thin and the pressure resistance is low. In addition, perfluorohexanone fire extinguishing agent has strong water absorption. During the process of opening the cover of the fire extinguishing agent barrel, it is very easy to come into contact with moisture in the air to produce hydrofluoric acid. Conventional heptafluoropropane fire extinguishing agent filling equipment cannot be used to fill perfluorohexanone fire extinguishing agent.
