Heptafluoropropane fire extinguishing system

Abstract

The invention relates to a heptafluoropropane fire extinguishing system. The heptafluoropropane fire extinguishing system comprises a fire extinguishing agent storing tank, the fire extinguishing agent storing tank is provided with a storing tank pressurizing control valve, the storing tank pressurizing control valve communicates with a pressurizing gas storing bottle assembly through a pressurizing gas pipeline, the fire extinguishing agent storing tank is further provided with a fire extinguishing agent releasing control valve, and a zone control valve is connected to the fire extinguishing agent releasing control valve through a fire extinguishing agent pipeline; a pipeline pressurizing control valve is arranged between the pressurizing gas pipeline and the fire extinguishing agent pipeline; the heptafluoropropane fire extinguishing system further comprises a control system, a weight detection device is arranged at the bottom of the fire extinguishing agent storing tank, and the control system is used for acquiring a signal of the weight detection device and controlling the fire extinguishing agent releasing control valve, the storing tank pressurizing control valve and the pipeline pressurizing control valve to be switched on and switched off. According to the heptafluoropropane fire extinguishing system, the weight detection device is used for monitoring the releasing amount of a fire extinguishing agent, and therefore the fire extinguishing system can achieve precise and quantitative releasing, has the higher usability and can flexibly distribute the fire extinguishing agent; meanwhile, the pipeline pressurizing control valve is arranged, and therefore it is guaranteed that the fire extinguishing agent can achieve the longer conveying distance.

Description

technical field [0001] The invention relates to a fire extinguishing system, in particular to a heptafluoropropane fire extinguishing system. Background technique [0002] The traditional gas fire extinguishing system mainly uses high-pressure steel cylinders to store fire extinguishing agent. In order to realize the fire extinguishing function, pressurized gas needs to be added to the high-pressure steel cylinders. According to the supplementary method of pressurized gas, the heptafluoropropane fire extinguishing system can be divided into internal pressure storage fire extinguishing system and external pressure storage fire extinguishing system. The difference between the system and the internal pressure storage system is that the pressurized gas is stored so that the fire extinguishing agent can be delivered to a longer distance. However, since the internal pressure storage and external pressure storage heptafluoropropane systems all use small-volume steel cylinders to s...

Problems solved by technology

However, reducing the reloading rate cannot fully satisfy the perfect protection of areas of different sizes. It will cause the large area to ignore the small area, which will lead to a large fire extinguishing dose, and the increase in the concentration of the protection area will cause personnel poisoning.
