Heat detection automatic fire extinguishing device

Abstract

The invention discloses a heat detection automatic fire extinguishing device. The heat detection automatic fire extinguishing device comprises a gas storage container, a fire extinguishing agent pipe,a temperature sensing fire valve and a release pipe, wherein the gas storage container is used for storing a fire extinguishing agent; the fire extinguishing agent pipe is used for being opened and closed to deliver the fire extinguishing agent and communicates with the gas storage container; the temperature sensing fire valve is used for sensing the temperature and controlling circulation of thefire extinguishing agent and is mounted at one end of the fire extinguishing agent pipe; the release pipe is used for delivering the fire extinguishing agent passing through the temperature sensing fire valve to a spray head to release outwards, one end of the release pipe is connected to the temperature sensing fire valve, and the other end of the release pipe is provided with the spray head. The heat detection automatic fire extinguishing device achieves the purposes of front temperature sensing and back fire extinguishing through the special temperature sensing fire valve, effectively andaccurately extinguishes the fire at the front high-temperature point and improves the fire extinguishing efficiency. Moreover, the heat detection automatic fire extinguishing device can be connected with multiple devices in parallel to realize linkage protection between multiple protection areas or the multiple devices. Once one device detects a fire point, the multiple devices connected in parallel starts simultaneously to conduct fire extinguishing so as to control the fire intensity, and the safety of facilities in the protection areas can be protected better.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a temperature-sensing detection automatic fire-extinguishing device. Background technique [0002] As an advanced fire extinguishing device, the temperature detection automatic fire extinguishing device has attracted much attention in the field of fire safety in server groups, power distribution rooms, electrical cabinets, mobile communication base stations and other facilities. The temperature detection automatic fire extinguishing device belongs to the fixed non-electric self-starting fire extinguishing device. This type of fire extinguishing device does not need power supply and traditional fire detection and alarm equipment. The whole device is often composed of a temperature detection device or a flexible fire detection tube. The starting method It is divided into two types: temperature-sensitive glass ball start-up and fire-detecting tube rupture start-up. [0003] S...

AI Technical Summary

Problems solved by technology

[0003] Since the starting temperature of the commonly used temperature-sensing glass bulb is 68°C and the operating temperature of the fire-detecting tube is about 160°C, the temperature-sensing glass bulb device and the fire-detecting tube device cannot be used at the same time. Equipped with a structure of the temperature-sensitive glass bulb or the fire detection tube, it is impossible to have both devices at the same time. When the purpose changes, the whole set of devices has to be replaced, resulting in double waste of economy and material

[0004] Furthermore, when the glass bulb structure is at the starting temperature, the organic solution in the temperature-sensitive glass bulb expands due to the temperature rise, breaking the glass bulb, and the seal is washed away by the fire extinguishing agent after losing the glass barrier, and sprays out along the glass bulb , to achieve the purpose of fire extinguishing; however, the common place for the temperature-sensing glass bulb structure device is the server room, the cooling fan blows the heat backward, and the glass bulb probe is also installed behind the server unit. Although the temperature sensing effect is good, the fire extinguishing agent is sprayed backward. , it is impossible to accurately extinguish the fire at the high temperature point in front, the fire extinguishing efficiency is low, and the fire extinguishing time is long

[0005] At the same time, many fire extinguishing devices used in the prior art can only protect one protection zone or one piece of equipment, and cannot realize the linkage protection of several protection zones or multiple pieces of equipment. Once the fire spreads, each piece of equipment needs to be individually temperature-sensitive to start fire extinguishing , the fire cannot be extinguished and controlled in time, and the safety is insufficient
