Description
Technical field
It the utility model is related to fire prevention ventilation equipment technical field, more particularly to a kind of fire resisting damper.
Background technology
Fire resisting damper be it is a kind of be used to be arranged at fire wall, when fire occurs, air channel and scene of fire can be blocked
Equipment.
Existing fire resisting damper, shut-off fire resisting damper is realized generally by the blade and its executing agency that are articulated with rotating shaft
Function, when fire resisting damper is opened, blade is rotated to horizontal level, prevent fires valve breakdown when, blade is rotated to vertical direction, led to
Often, fire resisting damper needs to set multiple blades, between blade and blade exist compared with Multiple level, and due to blade be provided with it is multiple, its
Executing agency is more complicated, therefore fire resisting damper parts are more and complicated.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, and shut-off is the few fire resisting damper in gap.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of fire resisting damper, including framework, the frame
Longitudinally disposed slot being provided with frame, the baffle plate for will be closed at the frame openings is plugged with the slot, it is described
The side of baffle plate is connected on thread bush by fusible alloy connecting rod, and the thread bush is internally threaded, the thread bush
The threaded connection is passed through by motor-driven leading screw with one；Temperature sensor, the framework are also equipped with the framework
Side be provided with control room, the motor is arranged on inside the control room, one end of the leading screw through the control room with
Its internal motor drive connection.
As preferable technical scheme, the thread bush quantity is two.
As preferable technical scheme, fusible alloy connecting rod includes two and fixes company with the baffle plate and thread bush respectively
The installation portion connect, and the fusing connecting portion of a connection fixed part, the diameter of the fusing connecting portion are less than the peace
The diameter in dress portion.
As preferable technical scheme, the side of the framework is additionally provided with guide groove, and the guide groove is longitudinally disposed, described
The side of baffle plate is provided with the roller moved along the guide groove.
As preferable technical scheme, Smoke Sensor is also equipped with the framework.
As preferable technical scheme, the slot bottom is provided with limiting plate, and installation limited location is opened below the limiting plate
Close, the limit switch is electrically connected with warning circuit.
By adopting the above-described technical solution, the beneficial effects of the utility model are：There is provided temperature biography for the utility model
Sensor, when temperature is higher than 80 DEG C, drives leading screw to rotate by motor, make thread bush drive baffle plate to move upwards, fire resisting damper is opened
Smoke evacuation is opened, because baffle plate is connected with thread bush by fusible alloy, fusible alloy fuses when temperature is higher than 280 DEG C, makes baffle plate
Support is lost, baffle plate falls under gravity, closes fire resisting damper.
The utility model turns off fire resisting damper by one piece of baffle plate, with turning off fire resisting damper using multiple blades in the prior art
Mode is compared, and gap is few, and sealing effect is good, and the utility model drives baffle plate to move unlatching fire resisting damper upwards by lead screw transmission,
Executing agency's automaticity is high, and simple and stable structure is strong, easy for installation.
