Abstract
An irrecoverable cable line-type fixed temperature detector consists of a connecting box, a terminal box, a temperature sensing cable. The utility model is characterized in that the structure of the temperature sensing cable is formed from a main conductor (1) having an outer heat-sensitive insulation coating layer (2) twined by an alloy conductor (3), which is arranged in an outer fire-retardant sheath layer (4) by the extrusion molding. The temperature sensing cable structure designed can be made into the products having a plurality of temperature grades; when the ambient temperature reaches a fixed alarm temperature grade set by a product, an alarm is given in time to prevent the fire from causing greater losses. The utility model has the advantages of the strong anti-electromagnetic interference, the high dependability of the product quality, the low cost, the simple temperature sensing cable structure, and adopts the conductor wrapped structure so as to make an external diameter of the cable small and flexible, the temperature sensing alarm more sensitive and accurate. The set working temperature range has six grades such as 60 DEG C, 70 DEG C, 85 DEG C, 105 DEG C, 138 DEG C, 180 DEG C, which totally are in accord with the requirement of the GB 16280 dash 2005 French quotes Line-type temperature sensing detector French quotes.
Description
Technical field
The utility model relates to the fire detector of fire-fighting domain, in a plurality of temperature grades the temperature value that sets is sent response, the cable linear constant temperature fire detector of output alarm signal.
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, the scene has been monitored in real time in order in time to grasp fire and fire preventing.Now the most linetype temperature-fixing fire detecting devices that use are to rise to when setting alarm temperature when scene temperature, promptly report to the police, finishing the single-stage of constant temperature reports to the police, the suitable environment temperature range is narrow, being subject to signal disturbs, wrong report probability height can not reach the requirement of GB16280-2005 " line-type heat detector ".
Summary of the invention
The purpose of this utility model is to provide a kind of Irrecoverable type cable type line type fixed temperature fire detector, improves reliability, reduces rate of false alarm, broad application temperature range.
Irrecoverable type cable type line type fixed temperature fire detector, form by terminal box, termination box, temperature sensing cable, it is characterized in that the structure of temperature sensing cable: the alloy conductor of quick insulating coating of leading body heat in the exterior, winding and the fire-retardant external sheath layer of extrusion molding.
The beneficial effects of the utility model and advantage:
1. the high gordian technique of the present utility model of reliability is the structure of temperature sensing cable, can be made into the product of a plurality of temperature grades, in time report to the police when a kind of product sets a certain fixedly alarm temperature grade, avoid fire to cause bigger loss when environment temperature reaches, anti-simultaneously electromagnetic interference (EMI) is strong, the product quality reliability height, cost is low, and temperature sensing cable is simple in structure, adopt wrapped conductor structure, make its external diameter little, flexibility is good, and it is sensitive, accurate that temperature-sensitive is reported to the police.
2. operating temperature meets the requirement of GB16280-2005 " line-type heat detector " fully.The operating temperature range that can set: 60 ℃, 70 ℃, 85 ℃, 105 ℃, 138 ℃, 180 ℃ six grades.
3, increase shielded conductor and plastic-aluminum combined belt, improved anti-electromagnetic interference (EMI) of cable and intensity.
