Description
The utility model relates to the Smoke proofing and fire proofing device that uses in a kind of building.
In some important buildings, generally be provided with automatic fire alarm system, need locate to set up defences fiery exhaust valve into and out of the air port at air conditioner, and controlled by the automatic fire alarm center.Existing Smoke prevention, fire resisting damper generally partly are made up of vane-type shutter, executing agency's part and electric wiring, and executing agency partly comprises DC electromagnet, is located at temperature fuse, microswitch and binding post on the valve.In use, fire resisting damper is often opened at ordinary times, when breaking out of fire, sends signal by the fire tele-control system, by executing agency, valve is closed automatically, with blocking-up flame, prevents fire spreading.But when the needs fire resisting damper was opened once more, valve can not automatically reset to the enable possition, must manually carry out vented exhaust, and this is in indoor particularly inconvenience when having toxic gas or fire resisting damper and being lifted on eminence.
The type Smoke proofing and fire proofing valve that automatically resets of the present utility model, partly form by vane-type shutter, executing agency's part and electric wiring, executing agency partly comprises DC electromagnet, is located at temperature fuse, microswitch and binding post on the valve, and it is characterized in that: executing agency partly comprises actuating mechanism and resetting-mechanism;
Be provided with locking device between DC electromagnet in the actuating mechanism and the temperature fuse, lever hook middle part in the locking device is fixed on the lock bracket, its end is relative with DC electromagnet, buckle end and temperature fuse plate washer join, the other end of temperature fuse plate washer is fixed on the lock bracket with spacing torsion spring, positive stop block one end and the vertical lock hanging of hook, the other end is fixed on the lock bracket with the positive stop block torsion spring, pressing plate one end and keying plate enable position valve main shaft on adjacent with positive stop block are corresponding, the other end is fixed on the lock bracket with hold-down plate spring, and torque adjustment bar and hand-reset handle are installed on the valve main shaft with the main shaft torsion spring;
Resetting-mechanism comprises micromachine, the speed change gear that is connected with micromachine, restoring link, microswitch and concavo-convex the wheel, one end of restoring link links to each other with the terminal gear of speed change gear, the other end links to each other with crank on the valve main shaft, and microswitch contacts with concavo-convex wheel the on being installed in the terminal teeth wheel shaft.
When air-conditioning system is equipped with many when automatically reseting type Smoke proofing and fire proofing valve, can adopt and tie, to realize synchronization action, synchronous reset, perhaps adopt the function of series wiring to realize that sequentially-operating, order reset.When system all adopts cigarette (temperature) sensor and automatic fire alarm control fire resisting damper, can be without temperature fuse, when temperature fuse fusing and after making valve closing, the temperature fuse link that must more renew just can automatically reset.
When the Smoke proofing and fire proofing valve does not need auto-reset function, executing agency can be divided into two, promptly actuating mechanism can be separated with resetting-mechanism.
According to the specification size of Smoke proofing and fire proofing valve, can regulate torsional moment by the torque adjustment bar, have the enough power of closing to guarantee the Smoke proofing and fire proofing valve.
According to the needs that the ventilation and air conditioning system air quantity is regulated, can regulate 8 class from being closed to standard-sized sheet by hand-reset handle controlling opening of valve.
The course of work of the present utility model:
1, when sending cigarette (temperature) electrification signal (DC24V), fire control centre passes through binding post 1 and 2, input dc power magnet, the adhesive of DC electromagnet iron core, affect hook and positive stop block on the locking device to throw off, the promotion pressing plate will be installed in the keying plate rotation on the valve main shaft, drive valve main shaft rapid valve-off under the effect of main shaft torsion spring.
2, when the fuse sheet on the temperature fuse fuses, the fuse plate washer rotates under spacing torsion spring effect in a clockwise direction, lead by pressing plate, promote to link up with positive stop block and throw off, at this moment, the valve main shaft passes through pressing plate, opens and closes plate rapid valve-off under the effect of main shaft torsion spring.
3, when fire control centre sends automatically or send the signal of telecommunication artificially, signal is by binding post 2 and 4 input micromachines, make its high rotating speed, low torque convert the slow-speed of revolution, high torque (HT) to by speed change gear, by the crank on the connecting rod driving valve main shaft, make valve reset and unlatching by terminal gear.The concavo-convex wheel with microswitch that is installed on the terminal gear worked simultaneously, and when valve reset arrived original opening, the microswitch inner contact was thrown off, and circuit cuts off automatically, and micromachine stops automatically.Valve resets to opening again.
This advantage that automatically resets type Smoke proofing and fire proofing valve is to realize that electronic Long-distance Control valve closes, automatically resets to the enable possition automatically, output valve shutdown signal simultaneously, and interlocking air conditioner equipment opens and closes; Can adjust its action moment of torsion, adjusting vane valve opening by the torque adjustment bar according to fire resisting damper specification size; The hand-reset handle, convenient manual open and close; Executing agency adopts lever locking device, and therefore, the work of electromagnet electric current only needs 0.27 to 0.3A, has reduced half than the action current of other hand-reset fire resisting damper.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model actuating mechanism and resetting-mechanism.
Fig. 6 is the restoring link device schematic diagram that the utility model resetting-mechanism links to each other with actuating mechanism.
