Description
Technical field
The present invention relates to automatic fire extinguisher, a kind of temperature-sensitive self-starting super-pressure extinguishing chemical releasing device.
Technical background
" Super fine dry powder automatic fir extinguisher for automobile engine house " of the prior art; Chinese patent ZL200520144740.9 with reference to shown in Figure 4, comprises extinguishing chemical cylindrical shell 1, constant temperature shower nozzle 2, superconduction hotness line 3 and pressure indicator 4; Extinguishing chemical cylindrical shell 1 is a kind of pressure vessel; In fill ultra-fine dry powder extinguishing agent and compressed nitrogen, operating pressure is 1.5Ppa, extinguishing chemical cylindrical shell 1 is provided with a spout; Spout place and extinguishing chemical cylindrical shell 1 that constant temperature shower nozzle 2 is arranged on extinguishing chemical cylindrical shell 1 form a closed container; Constant temperature shower nozzle 2 is the temperature-sensitive glass marble, and the temperature-sensitive glass marble is wound with superconduction hotness line 3 outward, and the other end of superconduction hotness line 3 is suspended in the automobile engine compartment, experiences the environment temperature in the storehouse, and can conduct the temperature-sensitive glass marble rapidly.On extinguishing chemical cylindrical shell 1, also be provided with pressure indicator 4, the operating pressure that can show in the extinguishing chemical cylindrical shell 1 through pressure indicator 4 at any time, if find that indicated pressure is lower than setting pressure, voltage supply in time guarantees that this extinguishing device is in running order all the time.
The shortcoming of this ultrafine dry powder extinguishing installation is: the temperature-sensitive glass marble directly withstands extinguishing chemical liberation port black box; Because the intensity of temperature-sensitive glass marble own is not high; Can not bear bigger operating pressure; The actual working pressure application 1 .2MPa～2MPa of temperature-sensitive glass marble can not satisfy the requirement of gases at high pressure extinguishing device operating pressure 2MPa～30MPa.
Summary of the invention
The purpose of this invention is to provide a kind of temperature-sensitive self-starting super-pressure extinguishing chemical releasing device, need not the power supply temperature-sensitive, discharge super-pressure extinguishing chemical valve by the environment temperature self-starting, and then release fire suppression agent is put out a fire.
Temperature-sensitive self-starting super-pressure extinguishing chemical releasing device of the present invention; Attaching nut by Blow head valve body one end links to each other with high-pressure extinction agent storage device; It is characterized in that settling in the T shape tubulose Blow head valve body horizontal cavity bump spring and impacting body wherein, bump cutter head; This end is installed shower nozzle outward, and the Blow head valve body other end is installed diaphragm, seal washer, and is fixed by the attaching nut; There is vertical hollow out frame at the Blow head valve body middle part and the phase through hole is arranged, and the temperature-sensitive glass marble is installed therebetween; The temperature-sensitive glass marble upper end of cylinder props up impacting body rear end lower edge, and the jackscrew of lower end bottom vertical hollow out frame is with its perpendicular positioning; Another program distinguishing characteristics is that temperature-sensitive glass marble upper end sets up the metal sliding pin, another scheme distinguishing characteristics be the slide post lower end for cylinder be the disk of one; Set up with the small diameter tube of horizontal cavity vertical connection in the hollow out rack space and set up another group spring and be placed in the small diameter tube, the temperature-sensitive glass marble is placed in the concave arc in the slide post lower disk surface center of circle.
The outstanding advantage of a kind of temperature-sensitive self-starting super-pressure extinguishing chemical releasing device of the present invention's design is:
Need not power supply temperature-sensitive self-starting super-pressure extinguishing chemical relief valve.Three kinds of schemes of the design are all with the explosion when environment temperature surpasses its bearing temperature of temperature-sensitive glass marble; After the explosion of temperature-sensitive glass marble, impacting body comes off, and the bump spring promotes impacting body and the bump cutter head impacts diaphragm rapidly; Make the diaphragm perforation; Extinguishing chemical discharges, and puts out a fire, and extinguishing chemical storage pressure is 2.5MPa～30MPa.This class formation has spring to increase impacting body release strength and reliability, can guarantee super-pressure extinguishing chemical safety storing, and the super-pressure extinguishing chemical sprays at once after the temperature-sensitive self-starting.
