Abstract
The utility model relates to a multi-stage alarm wire type temperature-sensing fire detector exclusively used for industrial fire fighting. The utility model which comprises an alarm cable is characterized in that metal wires (1) among which at least three metal wires are provided with encasing mould layers are intertwisted to make the alarm cable, an outer surface of the alarm cable is covered by a film adhesive tape inner protection layer (3) outside which a metallic screen jacket (5) is arranged.
Description
The utility model relates to the special-purpose multistage alarming line sensing fire detector of a kind of industrial fire, and this fire detector is the key detecting devices of industrial automatic fire protection system.
Cable type heat detector is a kind of fire detecting and alarm equipment that is widely used in the industrial fire field, up to the present, the product form of production and sales both at home and abroad mainly is the alarm cable detector of two cores, and this alarm cable does not often have metal screen layer outward.This detector is applied to that there are the following problems in the fire detection alarm system:
1, detector can only carry out one-level to fixing temperature and reports to the police, and is difficult to distinguish because the false alarm that mechanical damage or other non-fire and overheated factor cause, and rate of false alarm is higher;
2, because the alarm cable skin in this detector does not have the metallic shield net, detector easily is mechanically damaged, perishable, moisture-sensitive aging, reduced the reliability that equipment uses;
3, owing to can only single-stage report to the police, should not be used for the direct startup of automatic fire extinguishing system, if adopt the combinations of detectors of different temperatures grade, then cause the control system relative complex, engineering cost strengthens.
The purpose of this utility model is to provide a kind of novel industrial fire special-purpose multistage alarming line sensing fire detector, above multistage warning function, function of shielding, the water-proof functions of two-stage such as this detector can be realized forecasting, early warning, fire alarm, and can discern because the false alarm that mechanical damage or non-fire and overheated factor cause, rate of false alarm is extremely low.
The purpose of this utility model is realized by following technical scheme: the special-purpose multistage alarming line sensing fire detector of a kind of industrial fire, described alarm cable is to mould stranded the forming of tinsel of layer by having cover more than at least three, the outer wrapped film adhesive tape sheath of this alarm cable, this sheath is provided with metallic shield net sheath outward.
In order to improve water resistance of the present utility model, can outside described metallic shield net sheath, add the water-proof jacket of PVC material.In order to improve explosion-proof performance of the present utility model, can between described metallic shield net sheath and described sheath, add the sheath of PVC material.
Cover is moulded the temperature-sensitive insulating material that layer can be selected different response temperatures for use in the utility model, and the variation of the stranded joint square of tinsel in the variation by the temperature-sensitive insulation thickness, alarm cable, realize the multistage warning of forecast, early warning, fire alarm of synthermal grade or different temperatures grade; The employing of the water-proof jacket of metallic shield net sheath and PVC material can strengthen the anti-electromagnetic interference (EMI) of detector, anti-mechanical damage and Corrosion Protection.
The ultimate principle that the utility model is reported to the police is: have and have suitable stranded power after the steel wire of certain tensile strength or alloy skein silk close, when along some breaking out of fires of detector length direction or overheated, thermo-sensitive material reaches when softening response temperature, stranded tinsel will snap into and quote short-circuit signal together, and signal is handled by fire alarm control unit and determined false alarm, fire alarm or overtemperature signal.For the detector of many temperature grade alarm type, alerting signal will be quoted by order from low to high according to alarm cable temperature grade, the intersection on any order and putting upside down, and alerting signal all can be confirmed as false alarm.
Compared with the prior art the utility model has following advantage:
1, because alarm cable of the present utility model adopts the tinsel more than three, can realize the multistage warning of forecast, early warning, fire alarm of synthermal grade or different temperatures grade;
2, the utility model adopts metallic shield net sheath can strengthen anti-electromagnetic interference (EMI), the bruise resistance of detector.
3, the utility model adopts the water-proof jacket of PVC material can improve Corrosion Protection.
The utility model is described in further detail below in conjunction with drawings and Examples.

Referring to Fig. 1, Fig. 2 and Fig. 5, the fire detector of one of the utility model embodiment, alarm cable is arranged, described alarm cable is to have tinsel 1 stranded the forming that cover is moulded layer 2 by three, this tinsel can be coppered steel wire, zinc-coated wire, tin plated steel wire or alloy silk, and the stranded joint square of three wire is identical.It is the temperature-sensitive insulating material that described cover is moulded layer, the outer wrapped film adhesive tape sheath 3 of this alarm cable, and this sheath adopts the polyethylene film adhesive tape, and this sheath is provided with metallic shield net sheath 5 outward.In addition, the temperature-sensitive insulating material response temperature grade that described cover is moulded layer can be the same or different, and the stranded pitch of the 3rd wire can be identical or different with the stranded pitch of first and second wire.When temperature-sensitive insulating material response temperature grade was identical with twisting pitch, the two-stage that constitutes synthermal grade was reported to the police.Insulation temperature-sensitive material response temperature grade and twisting pitch constitute the two-stage warning of different temperatures grade not simultaneously.The method of the false alarm that identification mechanical damage, non-fire and non-overtemperature factor cause is to report to the police when one-level to occur, and does not still occur the second level after the certain hour section and reports to the police, and then being judged as is false alarm; For different temperatures grade type detector,, then be false alarm in addition if the high-temperature grade is reported to the police (being that high-temperature grade core snaps into owing to insulation course breaks with low temperature grade core) earlier.
Referring to Fig. 3, the detector in the present embodiment is the water proof type detector, and this detector is the improvement project on the basis of embodiment one, promptly adds the water sheath 4 of setting up defences at described metallic shield net sheath.This water-proof jacket adopts the PVC material, can play good protection against the tide, waterproof, corrosion-resisting function.
Referring to Fig. 4, the detector in the present embodiment is the explosion-proof type detector, and this detector is the improvement project on the basis of embodiment one, promptly is provided with water-proof jacket 4 between described metallic shield net sheath and described sheath.This detector can be widely used in the detection in industrial explosion-proof place.
Referring to Fig. 6, the alarm cable in the present embodiment adopts four wire.The stranded joint square of the wire in described alarm cable is greater than all the other stranded joint squares wiry.Promptly further stranded the 4th wire on the basis of first three wire generally adopts below five wire.The thermo-sensitive material that the metal silk braid is moulded can be selected three kinds of low temperature grade, middle temperature grade and high-temperature grades respectively for use, and in conjunction with different twisting pitch, alarm level is reported to the police corresponding to forecast, early warning, fire alarm secondary.The bar number of stranded wire is many more, and rate of false alarm is low more.But, use complicated more.
