? ? ? ? Among many fire extinguishing agents, Heptafluoropropane gas belongs to colorless, odorless, non-conductive and non-secondary pollution gas, which has the characteristics of cleanliness, low toxicity, good electric insulation and high fire extinguishing efficiency in the fire scene. Heptafluoropropane gas extinguisher adopts 304 stainless steel and carbon steel as the tank, and adopts Heptafluoropropane gas as the extinguishing agent. Through the Heptafluoropropane gas extinguishers, fire detectors, gas extinguishing controllers, acoustic and visual alarms, alarm bells, bleeder indicator lights, emergency start/stop buttons, and other related system components, Jian'an Firefighting can help the enterprise users to set up the Heptafluoropropane gas extinguishing system.
(i) Product characteristics of Heptafluoropropane gas fire extinguishers
General.Heptafluoropropane gas fire extinguisherIt is mainly composed of storage tank body, storage bottle group frame, gas check valve, manifold, control valve, elbow, reducer elbow, flange, safety valve, pressure signal transmitter and other components. At present, sevoflurane gas extinguishers on the market mainly use pipe network type, cabinet type and hanging type three kinds, and its on-site delivery distance is within 30 meters, and there is also a kind of external storage pressure sevoflurane gas extinguishers, and its delivery distance can reach 150 meters. In terms of extinguishing characteristics, Heptafluoropropane gas extinguisher adopts Heptafluoropropane gas as the extinguishing agent, which is overall neat and environmentally friendly, has good cleanliness, completely vaporizes in the atmosphere without residue, has good electrical insulation and high extinguishing efficiency.
? ? ? ? (ii) Precautions for Heptafluoropropane gas extinguishers
In Heptafluoropropane gas fire extinguishers, it is necessary to focus on the daily maintenance and inspection of container valves, manifolds, control valves, check valves, nozzles and valve actuators, and it is necessary to ensure that the conditions of the protective zone and the setting conditions of the extinguishing agent storage bottles are consistent with the design. Before starting to extinguish the fire, it is necessary to carefully check that the external surface of the heptafluoropropane gas extinguisher has no obvious deformation and damage, the surface coating is intact, while the interface threads and flange sealing surface are not damaged. As for the storage cylinder, the cylinder must be filled with Heptafluoropropane gas in accordance with the design requirements before installation, and the pressure surface on the head valve is installed towards the operation surface, while the installation height and direction need to be consistent.
The above is about the product characteristics and precautions of Heptafluoropropane gas fire extinguisher, which can be widely used in machine rooms, data centers, telecommunication projects, medical equipment, industrial equipment, archives, libraries, museums, distribution stations, flammable liquid storage tanks and other places with outstanding fire extinguishing advantages.
