Description
Technical field
The utility model relates to fire prevention field, specifically, and particularly a kind of spy fire-tube type temperature-sensitive self-starting extinguishing device.
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 hold-up vessel (being generally built-in with siphon pipe) of needs special use, adopts Seamless Steel bottle or welding bottle more, must need fix specially or vertically place when application.So, with fixedly extinguishing medium steel cylinder and built-in siphonal temperature-sensitive self-starting extinguishing device, be cannot be for the microenvironment of various dimensions activity, for example wind-powered electricity generation field needs the electrical control cubicles of 2-3 latitude rotation.
2. existing extinguishing device is normally comprised 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 to store separately, need to discharge by pipeline or nozzle during 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 ℃.Environment for use cannot be used when lower than 0 ℃ at that time.
Utility model content
The technical problem that the utility model actual needs 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.
The technical problem that the utility model solves 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 by 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, on described check valve assembly, be provided with for showing the leak detection Pressure gauge of internal pressure.
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, the beneficial effects of the utility model are 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 complicated facilities such as 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, so this device can provide the fire protection that cost performance is higher.
In sum, compared with prior art, progress of the present utility model 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, saved fire-extinguishing bottle, thereby made that total is more simple, reliable, fault rate is lower; Install more flexibly and easily, cost performance is higher.
