[0001] The utility model relates to the technical field of fire fighting, in particular to an external storage pressure boosting device for a heptafluoropropane fire extinguishing device. Background Art

[0002] Heptafluoropropane (HFC-227ea) is a commonly used gas fire extinguishing agent. It belongs to the class of hydrofluorocarbon compounds with a molecular formula of C3H2F7O. This compound is gaseous at room temperature and is non-flammable. This fire extinguishing agent has good fire extinguishing properties and can effectively extinguish Class A, Class B and Class C fires. This compound is gaseous at room temperature and has unique thermodynamic properties.

[0003] According to the Chinese patent with the announcement number CN209529966U, an external storage pressure heptafluoropropane fire extinguishing device is disclosed, including a bracket and a fire extinguishing agent bottle group. During the operation process, the current situation can be fed back to the external computer equipment through the signal feedback information, and the electromagnetic drive device is controlled to open, thereby driving the selection valve to open, and the pneumatic drive device is opened, so that the pressurized gas bottle group produces an internal and external pressure difference, and the fire extinguishing information can be remotely fed back through the signal feedback device, thereby providing safety monitoring at the fire extinguishing site, and the fire extinguishing agent can be quickly opened, so as to achieve a rapid fire extinguishing effect and improve the fire extinguishing efficiency. However, there are still certain shortcomings in the above patent when it is used.
