Abstract
The invention discloses a fire exploration pipe-type temperature-sensitive self-startup extinguishing device. The fire exploration pipe-type temperature-sensitive self-startup extinguishing device comprises a sealing container and a fire extinguishing agent sealed in the sealing container. The sealing container is prepared from a heat-sensitive material, the surface of the sealing container can be softened at a high temperature and be broken under the action of inner pressure so that a jet orifice is formed. The fire exploration pipe-type temperature-sensitive self-startup extinguishing device realizes combination of the exploration member, the extinguishing agent storage container and a conveying pipe. The exploration pipe is filled directly with the extinguishing agent and driving gas so that an extinguishing agent steel cylinder is avoided and the whole structure is simple and reliable, has a low failure rate, can be installed flexibly and conveniently and has a high cost performance.
Description
Technical field
The present invention relates to fire prevention field, specifically, particularly a kind of fire-tube type temperature-sensitive self-starting extinguishing device of visiting.
Background technology
In fire-fighting domain, temperature-sensitive self-starting extinguishing device occupies an important position always.Along with development for many years, domestic market has had spy fire-tube type temperature-sensitive self-starting extinguishing device, glass marble formula temperature-sensitive self-starting extinguishing device and fusible alloy temperature-sensitive self-starting extinguishing device substantially.
But existing temperature-sensitive self-starting extinguishing device still exists following problem:
1. current existing microenvironment temperature-sensitive self-starting extinguishing device, due to the special hold-up vessel of needs (being generally built-in with siphon pipe), adopts Seamless Steel bottle or welding bottle more, must need fix specially or vertically place in the time of application.So, be the microenvironment that cannot be used for various dimensions activity with fixing extinguishing medium steel cylinder and built-in siphonal temperature-sensitive self-starting extinguishing device, for example wind-powered electricity generation field needs the electrical control cubicles of 2-3 latitude rotation.
2. existing extinguishing device is normally made up of detecting element, extinguishing medium hold-up vessel, valve mechanism, discharge conduit or shower nozzle etc., structure relative complex, simultaneously construction also more complicated.Due to structure relative complex, trouble point increases greatly, and system is large at the failure likelihood at the crucial moment of catching fire, and is unfavorable for long-term maintenance.In addition, the existing extinguishing device that applies to microenvironment, because extinguishing chemical needs storage separately, need to discharge by pipeline or nozzle when system acting, has certain time delay.
For various for for the fire-fighting demand of microenvironment, the pharmaceutical quantities of microenvironment demand is original just few.For example volume is less than the electrical control cabinet of 1.5m3, only needs the FM200 medicament (heptafluoro-propane) of 1kg left and right can reach fire extinguishing effectiveness.Existing temperature-sensitive self-starting extinguishing device, just too large for this demand, and also relative price is too high.
Existing as its environment for use temperature range of carbon dioxide temperature-sensitive self-starting extinguishing device, the self-starting of heptafluoro-propane temperature-sensitive fire extinguishing assembling device be 0 ~ 50 DEG C.Environment for use was shown in and cannot uses when lower than 0 DEG C at that time.
Summary of the invention
The technical problem that actual needs of the present invention solves is: a kind of principle based on visiting fire-tube type temperature-sensitive self-starting extinguishing device is provided, in conjunction with the demand of microenvironment automatic fire control, visits more succinctly, efficiently fire-tube type tubular temperature-sensing self-starting extinguishing device.
Technical problem solved by the invention can realize by the following technical solutions:
Visit fire-tube type temperature-sensitive self-starting extinguishing device, it is characterized in that: comprise airtight container and be sealed in its inner extinguishing medium, described airtight container is made up of temperature-sensitive material, and its surface at high temperature can be softened and the formation jet that breaks under the effect of internal pressure.
Further, described airtight container is plastic alloy flexible pipe, and the port at plastic alloy flexible pipe two ends is hermetically-sealed construction.
Further, one end of described plastic alloy flexible pipe is provided with for the check valve assembly to its inner filling extinguishing medium.
Further, the leak detection Pressure gauge for showing internal pressure is installed on described check valve assembly.
Further, on described check valve assembly, pressure sensor is installed, described pressure sensor is used for connecting fire-alarm or fire central control unit.
Further, be also sealed with driving gas in described airtight container, described driving gas is inert gas.
Compared with prior art, beneficial effect of the present invention is as follows:
1. reliability is high.The operation principle that adopts temperature-sensitive spy fire-tube type, can be swift in response for the condition of a fire, extremely strong to the specific aim of incipient fire, and reliable operation, has hardly the possibility of misoperation.
2. simple in structure.Without fire-extinguishing bottle, do not need the Bottleneck valve that fault rate is higher yet, fire extinguishing action is very directly efficient.
3. easy for installation.While being applicable to small controller cabinet directly by pipeline colligation in cabinet, only within tens minutes, can install, do not need to install the facilities such as complicated steel cylinder completely and too much in electric-control cabinet body perforate.
4. wide adaptability.Because extinguishing medium and driving gas are directly sealed up for safekeeping in pipe, therefore as long as line arrangement is suitable, can be for the microenvironment fire-fighting of any various dimensions motion.
5. be swift in response.Because extinguishing medium and driving gas are directly sealed up for safekeeping in pipe, once therefore there is the condition of a fire, the medicament in pipe can directly spray to ignition point.
6. strong adaptability.When in the face of cryogenic applications, adopt inert gas as driving gas, select low temperature resistant extinguishing medium and low temperature resistant flexible conduit material simultaneously, can effectively tackle low temperature environment.
7. cost performance is high.When the microenvironment volume needing protection is little, often relative cost is higher to select traditional temperature-sensitive self-starting extinguishing device, even exceeds the real value of protected object.But fire risk can not reduce because of the height of protection price value, and therefore this device can provide the fire protection that cost performance is higher.
In sum, compared with prior art, progress of the present invention is: detecting element, foamite storage container and conveyance conduit are blended in to one, directly extinguishing chemical and driving gas are packed in sound-pipe, save fire-extinguishing bottle, thereby made that total is more simple, reliable, fault; Install more flexibly and easily, cost performance is higher.
