Perfluorinated hexanone suspended fire extinguishing device with temperature sensing and electric control dual start function

Abstract

The invention discloses a perfluorinated hexanone suspended fire extinguishing device with a temperature sensing and electric control dual start function. The device comprises a container filled withperfluorinated hexanone and high-pressure nitrogen, a valve body arranged on the container, a valve element, a nozzle, an electromagnetic driving device and a temperature sensing start device, whereinthe valve body comprises a branch pipe and a main pipe, the main pipe is provided with a first port and a second port, the second port is provided with a valve deck, the valve element is in sliding connection with the interior of the main pipe, the nozzle is arranged in the first port, and the electromagnetic driving device and the temperature sensing start device are arranged on the valve deck.The device further comprises a signal feedback device and a leakage detection instrument. The atomization nozzle, electric control start and temperature sensing automatic start functions are integrated, and the device is safe, reliable, reasonable in structural design, complete in overall function and high in practicability.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, more specifically, it relates to a perfluorohexanone suspension fire extinguishing device with temperature-sensing electric control and double start. Background technique [0002] In order to protect the ozone layer, my country joined the "Montreal Protocol on Substances that Deplete the Ozone Layer" and carried out the phase-out of substances that deplete the ozone layer. According to the requirements of the Montreal Protocol, my country needs to phase out the production and consumption of most ozone-depleting substances before 2030. The chemical code of perfluorohexanone fire extinguishing agent is FK-5-1-12, because of its low fire extinguishing concentration, low greenhouse effect potential value, short survival time in the atmosphere, easy transportation and storage, and little harm to human body, it is the current HFCs fire extinguishing agent. It is the most ideal substitu...

Problems solved by technology

The chemical code of perfluorohexanone fire extinguishing agent is FK-5-1-12, because of its low fire extinguishing concentration, low greenhouse effect potential value, short survival time in the atmosphere, easy transportation and storage, and little harm to human body, it is the current HFCs fire extinguishing agent. It is the most ideal substitute for perfluorohexanone fire extinguishing equipment in foreign countries. Although the synthesis technology of perfluorohexanone has been mastered in China, the supporting fire extinguishing device is still in a blank state.

[0003] At present, there are fire extinguishing devices suitable for heptafluoropropane and dry powder fire extinguishing agent on the market, but due to the physical characteristics of perfluorohexanone fire extinguishing agent and the difference in fire extinguishing mechanism, it cannot be directly applied, and the traditional hanging fire extinguishing device is only equipped with temperature-sensitive activation, which cannot pass The smoke alarm realizes remote electric control start, and there is a certain risk
