Description
The utility model relates to the Smoke proofing and fire proofing valve that uses in a kind of building.
In some important buildings, generally be provided with Automatic fire a1arm system, need on the sending of air conditioner, return air house steward and horizontal branch pipe, the Smoke proofing and fire proofing valve be set, and controlled by the automatic fire alarm center.Existing Smoke proofing and fire proofing valve generally partly is made up of vane-type shutter, actuating mechanism part and electric wiring, and actuating mechanism partly comprises DC electromagnet, is located at temperature fuse, sensitive switch and tenminal block on the valve.In use, fire-closing valve is opened usually, when breaking out of fire, sends signal by the fire tele-control system, by actuating mechanism, valve is closed automatically, with blocking-up flame, prevents fire spreading.The defective of existing Smoke proofing and fire proofing valve has: two heat responsive elements of temperature fuse easily come off, and cause the valve misoperation; When temperature fuse fusing, behind the valve closing, must be again with manually laying down the actuating mechanism panel, the temperature fuse that more renews, and the temperature fuse plate washer pushed the position.In addition, no on-site supervision device can not be realized the zoning or divide on-the-spot hand starting of floor and throttle down; No silicon rectifier can not AC/DC; Tenminal block is located at in-house, power line, construction wiring inconvenience when signaling line is introduced mechanism in actual engineering.Existing Smoke proofing and fire proofing valve can not satisfy the relevant requirements of existing fire protection rule.
The purpose of this utility model provides the full-automatic Smoke proofing and fire proofing valve of a kind of monitoring type, can automatically reset, and guarantees that valve misoperation can not take place, and has the characteristics of automatic monitoring, easy-to-connect.
The technological scheme of the full-automatic Smoke proofing and fire proofing valve of the utility model monitoring type: it comprises vane-type shutter, actuating mechanism, resetting-mechanism and control section, actuating mechanism comprises electromagnet, tenminal block, temperature fuse, sensitive switch, locking device and reseting handle, the torque adjustment plate, wherein locking device connects electromagnet and temperature fuse, it is characterized in that: temperature fuse is the scalable temperature fuse of heat expansion type, with in the locking device " " " shape temperature fuse baffle plate is connected, Lever type hook middle part in the locking device is fixed on the lock bracket, its end is relative with electromagnet, the buckle end and temperature fuse baffle plate one end of hook join, temperature fuse baffle plate middle part is connected on the support plate with torsion spring, and the other end is connected with temperature fuse; On lock bracket, connect postive stop baffle by spacing torsion spring, its end and hook lock hanging, the other end is connected with the keying plate that can stir the blade main shaft;
Control section comprises the on-site supervision device, and tenminal block usefulness lead one end on the monitoring unit is connected with the tenminal block on the resetting-mechanism, and the other end and fire control centre join.
The scalable temperature fuse of above-mentioned heat expansion type comprises flexible rod, the spring that is placed in successively on the main shaft and places thermal link and outer tube on the supporting mass.
Above-mentioned flexible rod is big, the inner little inclined-plane flexible rod in end, and spring is the turriform spring.
Above-mentioned on-site supervision device is made up of casing, switch, circuit board, tutorial light and tenminal block.
Above-mentioned actuating mechanism also comprises silicon rectifier.
When air-conditioning system is equipped with many full-automatic Smoke proofing and fire proofing valves, can adopt and tie, to realize synchronization motion, 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-closing valve, can adopt the DC24V electrical signal to make valve closing, also can adopt the temperature fuse action to make valve closing, when temperature fuse action and after making valve closing, do not need the temperature fuse that more renews, valve still can automatically reset.
When the Smoke proofing and fire proofing valve does not need auto-reset function, actuator can be divided into two, promptly actuating mechanism can be separated with resetting-mechanism.Actuating mechanism after the separation can be used in again on the electrodynamic type Smoke proofing and fire proofing valve.According to the specification size of Smoke proofing and fire proofing valve, can regulate moment of torsion moment by the torque adjustment plate, 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 be by hand reset handle controlling opening of valve, from being closed to 6 class of standard-sized sheet can regulate.
Working procedure of the present utility model:
1, when sending cigarette (temperature) electrification signal (DC24V), fire control centre passes through tenminal block, input dc power magnet, the adhesive of DC electromagnet iron core, affect hook and postive stop baffle on the locking device to throw off, drive is installed in the keying plate rotation on the blade main shaft, makes blade main shaft rapid throttle down under the effect of main shaft torsion spring.
2, when the thermal link on the temperature fuse moves, the fus baffle plate promotes to link up with postive stop baffle and throws off under the limit spring effect, and at this moment, the blade main shaft is by opening and closing plate rapid throttle down under the effect of main shaft torsion spring.
3, after the temperature fuse action makes valve closing, heat responsive element is under turriform spring and inclined-plane flexible rod effect, rely on the torsion spring power under the fus baffle plate to make hook and postive stop baffle sealed voluntarily, for electronic closing with the electronic unlatching that resets provides structural facility.
4, when fire control centre sends automatically or send electrical signal artificially, signal is imported micromachine by tenminal block, make its high rotating speed, low torque convert the slow-speed of revolution, high torque (HT) to by speed change gear, by the driving plate on the connecting rod drive vane main shaft, make valve reset and unlatching by terminal gear.The concavo-convex wheel with sensitive switch that is installed on the terminal teeth wheel shaft worked simultaneously, and when valve reset arrived original opening state, the sensitive switch inner contact was thrown off, and circuit cuts off automatically, and micromachine stops automatically.Valve resets to opening state again.
5, the on-site supervision device is installed in the bottom of Smoke proofing and fire proofing valve, apart from flooring or more than the ground 1.8 meters position, on the pipeline in valve is lifted on ceiling, manually during inconvenience, can utilize monitoring unit on-site manual button to connect power supply, the working state of check valve.
Advantage of the present utility model: improved temperature fuse and fus baffle shapes, adopted the scalable heat responsive element of heat expansion type, guaranteed that valve misoperation can not take place; No matter be the electromagnetic actuation valve closing, or fus action valve closing, all need not manually to change fus, realize full-automatic function.The on-site supervision device is set, can realize on-the-spot valve working state and the on-site manual opening/shutting valve of showing of branch floor, the electrical signal and the valve event signal that can directly show Fire Services Communication Centre output are convenient to working condition or on-call maintenance debugging fault valve that people grasp the Smoke proofing and fire proofing valve; Tenminal block is fixed on the resetting-mechanism in the actuator, and adds safety cover, and easy-to-connect need not be laid down panel and regulator plate again.Can be used for being provided with in tall building, public building, subsurface construction and water power, the thermal power project of Automatic fire a1arm system.
