Description
Technical field
The utility model relates to the fire detector of fire-fighting domain, a kind of recoverable cable linear constant temperature, different constant temperature fire detector.
Background technology
At present,, in a lot of buildings and the particular place fire detector has been installed, has been comprised line type fire detector in order in time to grasp fire and fire preventing.Line type fire detector remolding sensitivity in the middle of great majority use now is lower.The applicant's utility model patent formerly (ZL02273243.8), a kind of line type fire detector of renewable type can be monitored the wide temperature rate range.Owing in this patented technology, adopt the high resistant thermo-sensitive material, the processing technology more complicated, and decoding signals, termination box circuit are also complicated, the production cost height.Also have decoding signals, that termination box is influenced by envionmental humidity is bigger, Electromagnetic Compatibility is poor, the warning precision is low.This in addition exploration cable does not have explosion-proof function, therefore can't satisfy the performance requirement of GB16280-2005 " line-type heat detector ".
Summary of the invention
The purpose of this utility model is to provide a kind of renewable type cable linear constant temperature, different constant temperature fire detector, and improve reliability, different temperature grade and heating rate are made response, and reusable.
Renewable type cable linear constant temperature, different constant temperature fire detector, comprise decoding signals, terminal handler, temperature sensing cable, it is characterized in that the temp.-sensing wire cable structure: leading body has NTC temperature-sensitive insulation course outward respectively, the fire-retardant external sheath layer that whole plastic-aluminum that twines or copper are moulded superpacket belt and extrusion molding; Can there be one or one to mould outside the superpacket belt along being placed on outer and/or plastic-aluminum of NTC temperature-sensitive insulation course or copper with upper conductor and/or compensating wire.
The design's fire detector gordian technique is the structure of constant temperature, different constant temperature temperature sensing cable, it adopts NTC temperature-sensitive insulating material, temperature sensing cable value of having a resistance when temperature variation is changed, decoding signals adopts intellectualized technology that electric signal is carried out overall treatment, and variation of ambient temperature is sent alerting signal.The design's fire detector can possess constant temperature warning and two functions of differential temperature warning simultaneously, the constant temperature operating temperature that can set is: 60 ℃, 70 ℃, 85 ℃, 105 ℃, 138 ℃, 180 ℃ six grades, the temperature range that is suitable for is wide, is particularly useful for fire temperature rise ratio place faster.The differential temperature actuation of an alarm changes according to heating rate: 10 ℃/min (response in 20s～140s), 20 ℃/min (response in 22.5s～90s), 30 ℃/min (response in 15s～60s), and long service life, can be repeatedly used, can repeat at least 20 times through test.Because constant temperature, different constant temperature temperature sensing cable adopt wrapped conductor structure, make its external diameter little, temperature-sensitive is reported to the police and can be monitored in real time the acquisition environment temperature, and multistage constant temperature, twice type of alarm of many grades of differential temperature speed are highly sensitive, eliminates rate of false alarm.The no power of product own belongs to essential safe type, and good product quality, reliability height, cost is low, Installation and Debugging are easy to use, all satisfies the performance requirement of GB16280-2005 " line-type heat detector ".
