Description
Technical field
A kind of fire extinguishing system that the present invention relates to is utilized in fire extinguishing agent under the pressure and promptly visits the system that fire tube discharges fire extinguishing through the fusible hollow member of fusion.Especially relate to responsive to temperature and the spy fire tube of indication information is provided.
Background technology
A kind of extinguishing device that CN97193087 proposes is included in maintenance gas containers under the pressure, and design is in order to the fusible hollow member of drive unit.Fusible hollow member is connected on the foamite container, so that it can be excited by the pressure gas in the container.Between foamite container and fusible hollow member, pressure governor is housed.Pressure governor can make device ejection fire extinguishing agent, for example adopts CO
2As fire extinguishing agent.
Said fusible hollow member is promptly visited fire tube; The existing fire extinguishing system of visiting fire tube of utilizing has begun to use; The electric fire extinguishing system that starts of promptly so-called nothing: be made up of spy fire tube, air valve, firing-fighting medium reservoir, alarm, temperature melts above visiting the fire tube fusing point when visiting the fire tube chance condition of a fire, and the firing-fighting medium reservoir is the band pressure vessel; The firing-fighting medium of storage discharges by starting air valve under pressure, the release fire suppression agent fire extinguishing.
Yet, because existing spy fire tube all is to be prepared by macromolecular material.Spy fire tube product system like Rotarex S.A (the plug Order restrains this) company adopts the nylon base preparation.Typical alarm temperature is provided with 160-180 ℃, can not have any information transfer capability at present but visit fire tube, only if when environment temperature arrives 160-180 ℃, and the fire extinguishing that starts after the fusion, the system that does not have the early warning of responsive to temperature indication information occurs.
Yet; Existing spy fire tube by the macromolecular material preparation is being used for beginning to have application on the industry unmanned work base stations such as electrical equipment, control electronics, the vehicles, aerogenerator; Different with traditional intelligent building fire-fighting system, directly do not export potential temperature anomaly early warning information.Though the spy fire tube of macromolecular material preparation is equally distributed in shielded cabin when layout, this helps exporting protected object for information about.Especially under the situation of inferior fire, temperature is very high, and it is very important that tangible early warning indication can be arranged.
Summary of the invention
The present invention seeks to, propose a kind of spy fire tube that indicated temperature information is provided.Especially be applicable to the fire extinguishing system of warm start, especially proposed through when extruding manufacturing, adopting blending technology adding up-conversion luminescent material, thermic to respond the reversible color luminescent material or above-mentioned two kinds of materials being carried out continuous strip coating at the side surface length direction of visiting fire tube.Indication information in the time of can providing temperature higher, especially the temperature early warning information more than 75 degrees centigrade, and the indication of significantly unusual position can by day or all can be provided under the situation of unglazed photograph.
Goal of the invention also is, especially proposes visiting on the fire tube infrared excitation fluorescence luminescent material or applying the polymer-base thermosensitive resistance material simultaneously and thermosensitive pigment may is contained in institute through continuously coating.Indication information in the time of can providing temperature higher, the especially temperature information more than 75 degrees centigrade, and tangible early warning indication can by day or all can be provided under the situation of unglazed photograph.
Technical scheme of the present invention is: the spy fire tube with indication information; Adopt macromolecular material to visit fire tube, adopt the blend extruding technology to add macromolecular material when making or carry out continuous strip and be coated with and be laid with the infrared excitation fluorescence luminescent material visiting fire tube side surface length direction extruding.
The present invention improves: add ultraviolet excited fluorescence luminescent material, thermosensitive chromotropic material simultaneously.
It is to add thermosensitive chromotropic material on the basis of the above simultaneously that the present invention improves.
At the side surface length direction of the spy fire tube of the polymeric material strip thermosensitive luminescence material temperature marker of fitting continuously.
Two relative sides are provided with infrared, ultraviolet excited fluorescence luminescent material temperature marker in four sides of tube wall, and vertical therewith two relative sides apply thermosensitive luminescence material temperature marker.
