Abstract
The utility model belongs to the fire-fighting filed, in particular to a multi-grade alarming line type constant temperature fire detecting cable which monitors the fire parameters of the protected objects to produce alarming signal by detecting the changes of resistance value of the wire core. The utility model is characterized in that a thin sheet of stripped conductor is clipped between two wrung wire cores of stressed plastic heat-sensitive insulation material; the thin sheet of stripped conductor winds an inner belting and then stresses an outer sheath. The utility model can alarm correctly. Thus, the fire detector can alarm in different time of the fire, which is favorable to improve the correctness of the fire alarming and effectively reduce the possibility of false alarming. The utility model has the advantages of simple structure and advanced cabling process.
Description
Technical field
The utility model belongs to fire-fighting domain, specifically by detecting the fire parameter of the change in resistance monitoring and protecting object between the core, produces the multistage warning linetype temperature-fixing fire detecting cable of alerting signal.
Background technology
The existing cable that is used for fire is generally two wire outer coated sheaths and constitutes, and this cable can only be finished the single-stage of constant temperature and report to the police, and is easy to be subjected to signal to disturb and reports by mistake.
Summary of the invention
The purpose of this utility model is the new structure that proposes a kind of multistage warning, and the line of linetype temperature-fixing fire detecting cable is directly dwindled, and is easy to stranding, and the finished product flexibility is good, sets up easily.
The utility model is formed by two elastic wire cores (1) extrusion molding different temperatures grade temperature-sensitive insulating material (2) pair twist, and between presss from both sides a thin slice tape conductor (3) as public pole, band (4) back extrusion molding oversheath (5) in twining then.According to the difference of object of protection, can also be woven with protective seam (6) respectively.Material as protective seam (6) can be respectively according to the place operating position:
Man-made fiber----is used for outdoor location;
Tinsel----is used to have electromagnetic interference (EMI) need shield the place;
High desnity metal silk----is used for explosion-proof place.
When the temperature at scene rises to the lower temperature grade of multistage warning line style constant temperature fire detector setting, send fire alarm, reminds people is noted, so that check on-the-spot; When fire continues development, when temperature rises to the high-temperature grade, can accurately report fire alarm.Reach a kind of fire detector like this and report to the police respectively different opportunitys, help to improve the accuracy of fire alarm, effectively reduce the possibility of wrong report at fire.And have advantages such as simple in structure, cabling process advanced person.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is used for the general module wiring schematic diagram for the utility model.
Fig. 3 is used for the interface module synoptic diagram for the utility model.
Embodiment
The temperature-sensitive insulating material (2) of two cores of the present utility model (1) extrusion molding and temperature grade are two-stage different temperatures grade.
The utility model is used for interface module, can be by the interface module switching of two common one pole linetype temperature-fixing fire detecting devices, and two temperature form two coded addresses, fire signal are sent, as shown in Figure 2.21 is interface module among the figure, and 22 is low temperature grade core, and 23 is high-temperature grade core, and 24 is public pole, and 25 is terminal module.Also can connect by a sophisticated interface module, send two coded addresses by signal bus, sophisticated interface module directly forms the fire signal of two different times, and two cores (1) and public pole (3) can directly be connected on the sophisticated interface module respective terminal, as shown in Figure 3.31 is signal bus among the figure, and 32 is sophisticated interface module, and 33 is low temperature grade core, and 34 is high-temperature grade core, and 35 is public pole, and 36 is terminal module.
Claims (3)
1. a multistage warning linetype temperature-fixing fire detecting cable has core and sheath, and two strands that it is characterized in that extrusion molding temperature-sensitive insulating material (2) are twined interior band (4) back extrusion molding oversheath (5) to folder one thin slice tape conductor (3) between the core (1).
2. according to the described multistage warning linetype temperature-fixing fire detecting cable of claim 1, it is characterized in that the temperature grade of the temperature-sensitive insulating material (2) of two cores (1) extrusion molding is two-stage.
