Description
Technical field
It the utility model is related to fire resisting damper, more particularly to fire resisting damper control system on the spot.
Background technology
At present, high-rise is fitted with ventilation shaft, and fire resisting damper is equipped with ventilation shaft.Fire resisting damper include valve body and
The executing agency being fixed on outside valve body, the passage of valve body is interior to be equipped with valve block, and main shaft is fixed with valve block, and main shaft is stretched out outside valve body
And it is connected with executing agency.Executing agency so as to be rotated with moving valve plate, and then realizes opening for whole valve body by rotating main shaft
Close, as valve block it is parallel with the cross section of the passage in valve body when, valve block blocks passage, valve body closure, in valve block and valve body
When the cross section of passage is vertical, the aperture of whole valve body is maximum.
In order to realize automated control, warming structure, such as Publication No. are installed mostly in fire resisting damper
Pressure air blowing mouth smoke-exhaust fire valve actuating mechanism disclosed in the utility model patent of CN205578852U, including heat detector structure,
Heat detector structure includes temperature control safety plate.In the too high temperature of air that heat detector structure detection passes through into vent passages
（When fire occurs）, temperature control safety plate is blown, and actuating mechanism controls fire resisting damper blocks vent passages.
Although the fire resisting damper of this structure enables to fire resisting damper to sense fire action, still, due to temperature control safety plate
It has been blown when sensing fire, so the close fire prevention valve replacement temperature control safety plate of staff is needed when resetting fire resisting damper,
Then fire resisting damper could be resetted.In the prior art, the position of vent passages is generally higher, this just needs staff to climb completion
The work of fire resisting damper is resetted, resetting work for solenoid valve causes trouble.
Utility model content
The purpose of this utility model is to provide a kind of fire resisting damper control system on the spot, control system makes the fire resisting damper on the spot
Obtain the reset fire resisting damper that staff can be more convenient.
The above-mentioned purpose of the utility model technical scheme is that：

Including the control box on the spot set close to ground, the control box on the spot is provided with the control circuit of control executing agency action,
Control circuit includes
Warming control module, for detecting the temperature of the air by valve body, and it is big in the temperature of the air by valve body
Output temperature control signal when preset value；
Execution module, couples warming control module, is divulged information under normal conditions by actuating mechanism controls valve body, and temperature controlled
Executing agency's action is controlled after signal trigger action, so that valve block blocks valve body；
Reseting module, couples execution module, for exporting reset signal, is preset when the temperature of the air by valve body is less than
During value, the execution module response reset signal is divulged information by actuating mechanism controls valve body.
By using above-mentioned technical proposal, by being arranged close to the control box on the spot on ground, staff can be facilitated remote
Process control executing agency acts；When a fire, raised by the air themperature of fire resisting damper, warming control module output temperature
Control signal, at this time, controls executing agency's action to see so that valve block is continuously in after the triggering of execution module hand temperature control signals
The state of valve body is blocked, after fire, warming control module stops output temperature control signal, at this time, passes through reseting module
Control executing agency returns to normal, and then fire resisting damper is recovered ventilation state；Fire prevention is resetted so as to eliminate staff and climb
The process of valve, simplifies the course of work for resetting fire resisting damper.
As the improvement of the utility model, the executing agency is including being vertically fixedly connected with the drive link of main shaft, fixation is set
Put the magnetic induction loop on the outside of valve body and be used to drive the opposite main axis drive rod of drive link, institute with merging with magnetic induction loop
It is magnetic shaft to state drive rod, and under normality, magnetic induction loop is powered, and the valve body is in can ventilation state.
By using above-mentioned technical proposal, since drive rod is magnetic shaft, when magnetic induction loop is powered, magnetic field can be produced,
So as to drive drive rod to move, and then rotated by drive link drive shaft, to achieve the purpose that to control valve block to rotate；Magnetic at the same time
The mode of sensing control, which implements, to be relatively easy to, and of low cost.
As the improvement of the utility model, the warming control module includes
Temperature detecting unit, is arranged in ventilation shaft, for detecting the temperature of the air by valve body, and corresponding output
Temperature detection signal；
Temperature reference unit, for providing a temperature reference signal；
Temperature comparing unit couples temperature detecting unit and temperature reference unit, for receiving temperature detection signal and temperature
Reference signal, the temperature control signals are exported when temperature detection signal is more than temperature reference signal.
By using above-mentioned technical proposal, pass through set temperature reference cell and temperature comparing unit so that only logical
When crossing the temperature of the air of valve body and being higher than certain value, warming control module just can output temperature control signal.
As the improvement of the utility model, the execution module includes controlling the magnetic induction loop to obtain electric or dead electricity control
Unit and relay, after the execution module signal trigger action temperature controlled, the coil of relay is powered, the relay
The normally-closed contact of device is arranged in series with described control unit.

The normally-closed contact of device is arranged in series with control unit, so, when the coil of relay obtains electric, it can be achieved that making control unit break
Electricity, so that haveed the function that to control magnetic induction loop by relay, and the control mode of relay is more mature, in certain journey
The control mode of magnetic induction loop is reduced on degree.
As the improvement of the utility model, the reseting module includes reset button, and the coil response of the relay is multiple
The closure dead electricity of position button.
By using above-mentioned technical proposal, due to the closure dead electricity of the coil response reset button of relay, pressed so working as
During lower reset button, the coil losing electricity for the relay that can make, so that control unit powers off, i.e., magnetic induction loop powers off, so that
Execution module is set to return to normality.
As the improvement of the utility model, fuse is further included, the reset button couples power supply by fuse and bears
Pole, the fuse response temperature control signals disconnect.
By using above-mentioned technical proposal, since reset button is by fuse coupling power cathode, when fuse disconnects
When energization branch circuit break where reset button so that reset button cannot play reset response, and because fuse response temperature
Control signal disconnects, so after fire resisting damper is closed due to generation fire, fire resisting damper can be caused by only replacing fuse
Reset, play the role of preventing maloperation to a certain extent.
In conclusion the utility model has the advantages that：
First, safe operation, when a fire, the coil losing electricity of relay, control unit control magnetic induction loop dead electricity,
So as to have the function that to control fire resisting damper closure；Meanwhile after fire resisting damper closes, fuse fuses at the same time, only more renews
Fuse could reset fire resisting damper again through reset button, reduce to a certain extent since maloperation causes fire resisting damper to lead to
The occurrence of probability of wind；
2nd, it is easy to operate, it only need to be the reset that can be achieved to fire resisting damper by control box on the spot, eliminate staff and climb
Height resets the course of work of fire resisting damper.
