Instruction manual for driving gas cylinder group of heptafluoropropane fire extinguishing equipment

1. The structure of the driving gas cylinder group for heptafluoropropane fire extinguishing equipment consists of a storage container, container valve, driving gas (N2), safety relief device, and pressure display; Its storage pressure is 6MPa (20 ℃), maximum working pressure is 6.6MPa (50 ℃), working temperature range: 0 ℃~50 ℃; Filling pressure: 6MPa (20 ℃).

2. The working principle of the driving gas cylinder group for heptafluoropropane fire extinguishing equipment is that the storage container is a seamless pressure vessel, and the driving gas (N2) is stored in the container in gaseous form. When a fire occurs in the protected area, the fire alarm controller outputs DC-24V current, connects the electromagnet in the electromagnetic drive device, and the electromagnet acts to push the puncture device (puncture needle) in the electromagnetic drive device. The puncture needle penetrates the sealing membrane of the container valve and opens the container valve; Release N2 gas from the outlet of the container valve. After driving the pipeline, open the selector valve, open the one-way valve in the driving pipeline, and open the container valve of the fire extinguishing agent bottle group.

3. In case of emergency, the manual button safety pin can also be pulled out, the button can be pressed, and the puncture needle in the electromagnetic drive device can penetrate the sealing membrane of the container valve to open the container valve; Release N2 gas from the outlet of the container valve.

4. The heptafluoropropane fire extinguishing equipment is equipped with a safety relief device (safety relief diaphragm release pressure 9MPa ± 5%) on the container valve of the driving gas cylinder group, which is used to prevent the pressure inside the driving gas storage cylinder from being too high. The pressure relief is adopted to protect the safety of the storage cylinder. If the safety film is activated, after the pressure of the storage bottle is released, a new safety release film should be replaced and a sealing test should be conducted before putting it into use. After the heptafluoropropane fire extinguishing equipment drives the gas cylinder group to operate normally, it is necessary to replace the sealing membrane of the container valve, conduct strength and sealing tests, and then put it into use. When replacing the safety relief membrane or sealing membrane, it must be exactly the same model and specification as the original membrane, and cannot be replaced arbitrarily.

5. The driving gas cylinder group of heptafluoropropane fire extinguishing equipment is impacted by the driving gas spray when starting, and should be fixed during installation.

6. The driving gas cylinder group of heptafluoropropane fire extinguishing equipment contains high-pressure gas inside the cylinder, and inversion is strictly prohibited! Be cautious and handle with care! Avoid direct sunlight exposure! The outlet of the container valve is equipped with a protective cap to prevent accidental spraying, which is connected to the valve body with a chain. When handling, this protective cap should be covered to prevent accidental release of driving gas, which may cause the driving gas cylinder group to fall and injure personnel; It is strictly prohibited to dismantle equipment and components without authorization! The driving gas used for filling is high-pressure gas. If the filling process is not handled properly, there may be certain dangers. Therefore, it is recommended that the filling of the driving gas be carried out by the supplier or by professional personnel according to requirements when refilling.
