Description
Technical field
The utility model belongs to building installation engineering technical field, particularly relates to a kind of high-rise residential building flue anti-fire control system.
Background technology
Along with expanding economy, the people made start health standards and the environment of paying close attention to shelter, and increasing resident requires to promote house health standards, and this proposes new problem to the builder of Modern Residence and manager.Part building expert points out that the main leak that current house exists on Construction and management is: trench general smelly, flue gas stream recharges, it is smooth to ventilate, garbage chute opens wide, upper water pollutions and building gap, the two large principal elements wherein affecting air quality of indoor of housing are: the common flue oil smoke taint of odour of residential building kitchen and toilet exhaust emission.Promote house health standards, the problems demand of air quality of indoor of housing aspect solves.
Common flue, refers to the vertical smokejack for kitchen discharge oil smoke and cooking waste gas in house.Built most of residential quarters be improve ventilation shaft air draft ability, prevent dirty gas crossfire, in toilet and kitchen, the ventilation shaft passing through each floor is all vertically set, ventilating fan and smoke exhaust ventilator are installed by after the fume collection in each floor toilet and kitchen by resident oneself, concentrate and discharge.Flue is for improving air quality in house, and reduce kitchen pollution harm, improving indoor sanitation condition has important effect, is also one of important means improving IAQ.But because existing construction standards are indefinite for the requirement of flue sectional area and discharge capacity, cause current residence chimney neck market more chaotic, new technology adopts ineffective, cause the flue sectional area of high residential building general less, discharge capacity is not enough.Often flue has become " air garbage chute ".This is pollution sources of residential households air, has had a strong impact on resident's living quality, and the problem therefore how solving dirty gas crossfire in high residential building seems very important.
At present, the valve plate seal form of the check-valves that high-rise residential building common flue is arranged mostly is and relies on gravity sealing, and namely valve plate naturally droops and covers the mouth of pipe under gravity.When exhaust equipment work such as lampblack absorbers, rely on blast to be backed down by valve plate, therefore valve plate weight also can not be very large, and little weight causes sealing not tight.Also can cause extra burden to exhaust equipments such as lampblack absorbers simultaneously.Check-valves on existing a lot of common flue does not possess sealing fireproof function.Once the low floor generation condition of a fire, the intensity of a fire can in common flue rapid spread, and from check-valves overflow cause high-storey to catch fire.There is part check valve to possess fire resistance property, need hand-reset, and operation inconvenience, need check-valves dismounting to reset.Once because other reason causes these check-valves possessing fire resistance property surprisingly to trigger fire prevention insurance in common flue, a lot of inconvenience will be brought to user.
Utility model content
The utility model, in order to solve weak point of the prior art, provides that a kind of automaticity is high, security reliability is strong, can close the high-rise residential building flue anti-fire control system of flue by automatic fire prevention.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: high-rise residential building flue anti-fire control system, comprise installing plate and upper and lower two ends and be connected to cylinder on flue, fixedly establish on a mounting board outside cylinder, cylinder inwall is provided with the location ring flat-plate of cirque structure, location ring flat-plate lower surface is provided with the seal groove of annular, soft flexible seal washer is provided with in seal groove, the sealing plate being positioned at rounded structure below the ring flat-plate of location is provided with in cylinder, the external diameter of sealing plate is less than the internal diameter of cylinder, sealing plate is rotatably connected on cylinder by hinge, sealing plate upper surface outward flange is provided with the sealing ring that can extend into seal washer press fit in seal groove, installing plate is provided with fireproof box and for driving the power-driven mechanism of sealing plate opening and closing, mount pad is provided with in described flue,
Fireproof box inwall is provided with thermal insulation layer, is provided with controller in fireproof box, and mount pad is provided with Smoke Sensor and temperature sensor, and controller is connected with Smoke Sensor and temperature sensor respectively by the first fireproof cable control line;
Power-driven mechanism comprises fork, connecting rod, lower square tube and upper square tube, lower square tube and upper square tube are all vertically set on installing plate, lower square tube upper end open is corresponding with upper square tube lower ending opening and connect, upper square tube upper end shutoff, lower square tube side is provided with install bin, servomotor and gear is provided with in install bin, the main shaft of servomotor is connected with gear drive, slide in upper square tube and be provided with tooth bar, top tube side part is provided with the elongated hole be communicated with lower square tube inside by install bin, and gear is connected with a joggle through elongated hole and tooth bar; Slide in upper square tube and be provided with slide block, upper square tube side is vertically provided with pilot hole, be connected by pull bar between slide block lower surface with tooth bar upper end, fork one end is connected with sealing plate by described hinge, the fork other end and connecting rod one end hinged, the connecting rod other end is hinged on slide block through pilot hole;
Controller is connected with servomotor by the second fireproof cable control line.
Install bin is provided with the screw be positioned at directly over gear, and screw internal thread is connected with bolt.
Adopt technique scheme, controller of the present utility model can be disposed in the interior, and normal condition keeps "on" position.When lampblack absorber works, controller sends signal to servomotor, servomotor driven gear rotates, gear driving rack moves up along lower square tube, tooth bar upper end drives slide block to move up along upper square tube by pull bar, the connecting rod hinged with slide block drives fork upwards to rotate, and fork drives sealing plate to be that fulcrum rotates with hinge, is so just opened by common flue.When lampblack absorber is closed, controller is given an order to servomotor, drives sealing plate to be closed by flue.When there being the condition of a fire to occur in common flue, Smoke Sensor detects that dense smoke and temperature sensor detect that the signal of gas temperature sends controller to, and controller is given an order to servomotor, drives sealing plate to be closed by flue.So just flue is closed, avoid the intensity of a fire in common flue to vertical spread.
The utility model is equivalent on flue, arrange one valve, and the sealing ring that sealing plate is arranged coordinates with the seal washer in locating slot on the ring flat-plate of location, guarantees the tight shape sealed.The driving rotating through pinion and rack and sliding-block linkage of sealing plate, be easy to manufacture and workable.Servomotor adopts the mode automatically controlled, and automaticity is high, and controller is arranged in fireproof box, avoids the impact of high temperature on controller to cause the malfunctioning of controller.Screw on install bin is oil filler point, can lubricate by gear, guarantees powerdriven flexibility.
In sum, the utility model structure is simple, reasonable in design, adopt the mode driven wheel tooth bar mechanism of control automatically and sliding-block linkage to realize sealing plate flue is closed automatically and opens, automaticity is high, fire line is good, security reliability is strong, practical, is easy to apply.
