Problems solved by technology

[0003] The disadvantage of this ultra-fine dry powder fire extinguishing device is: the temperature-sensing glass ball directly withstands the sealing assembly of the fire extinguishing agent release port. Since the temperature-sensing glass ball itself is not strong enough, it cannot withstand a large working pressure. The actual working pressure of the temperature-sensing glass ball The application range is 1.2MPa ~ 2MPa, so the fire extinguishing device with this structure has a limited application range. It is only suitable for the working pressure of the fire extinguishing agent cylinder is 1.5Ppa, and cannot meet the requirements of the high pressure gas fire extinguishing device working pressure of 2MPa ~ 30MPa

Embodiment 1

[0016] The linear temperature-sensing self-starting ultra-high pressure fire extinguishing agent release device of the present invention is suitable for gas fire extinguishing agents, see figure 2 , the tank valve 23 gas outlet pipeline of the fire extinguishing agent gas storage tank 24 is connected to the interface nut 21 of the air inlet on the upper end of the nozzle valve body 16 and the inlet end of the linear temperature-sensing detection tube 13, which is characterized in that the nozzle valve body 16 is axially The cavity is equipped with an impact body 1, a starting spring 17, and an impact cutter head 18, and one end of the nozzle valve body 16 is equipped with a nozzle 2, see image 3 , 4 , the other end is installed with a diaphragm 19, a sealing washer 20 and a connecting nut 21; figure 2 , 6 It can be seen that there are two holes on one side of the protruding part of the middle part of the nozzle valve body 1, and the gas detection pipe joint 12 is installe...

Embodiment 2

[0021] Because the linear temperature-sensing detection tube 13 is connected to the high-pressure fire extinguishing agent storage device 24, the tube wall bears a certain pressure, so the pressure range, material and manufacturing process should be considered. The easy way is to set a tank valve 23 at the outlet of the high-pressure fire extinguishing agent storage device 24, and add a pressure reducing valve 22, and then connect with the linear temperature-sensing detection pipe 13, thereby reducing the pressure of the linear temperature-sensing detection pipe 13, and also Reduce manufacturing costs. The working pressure of the air inlet end of the decompression valve 22 is 0-30 MPa, and the working pressure of the air outlet end is 0-2 MPa.

[0022] The material used in the present invention is:

[0023] 1. Linear temperature sensing tube: outer diameter 3-6mm, inner diameter 1-4mm, made of nylon, polyethylene, polypropylene and other polymer materials.

[0024] 2. Diaphr...

Abstract

The invention provides a line-type temperature-sensing self-starting extra-high-pressure fire extinguishing agent release device. The release device is characterized in that a cavity of a sprayer valve body is internally provided with an impactor and an impact cutting head, one end of the sprayer valve body is provided with a sprayer and the other end is provided with a diaphragm; an upper hole at the middle part of the sprayer valve body is provided with a line-type temperature-sensing detection tube and a piston, and a lower hole at the middle part of the sprayer valve body is provided with a microswitch; the rear end of a piston shell is provided with a safety pin and a shaft pin, the shaft pin is connected with a transmission shaft, the tail end of a transmission sleeve is radially provided with a half-moon shaft and is positioned by a cotter pin radially passing through the half-moon shaft, so that an entity in a concave part of the half-moon shaft pushes against a boss part of the impactor for realizing positioning; and a cavity of the rear end of the piston is internally provided with a reset spring which is positioned in the upper hole through a nut. When the ambient temperature reaches or exceeds a set value, the line-type temperature-sensing detection tube explodes to release pressure to enable the reset spring to push the piston to move, drive the displacement of the half-moon shaft, enable the impactor to fall off and enable the impact cutting head to quickly impact diaphragm to realize punching, and thus the release device can be started for extinguishing fire. In addition, the storage pressure of the fire extinguishing agent is 2-30 MPa, no power supply is needed, the line-type temperature-sensing detection tube has a large protection range and the storage pressure of the fire extinguishing agent is high.
