Description
Technical field
The utility model relates to exhaust duct import guiding device, has related in particular to a kind of fireproof exhaust passage import transformation guiding device.
Background technology
Concentrate in the exhaust passage system at residential kitchen and toilet, consistent with the flow of flue gas direction for making oil smoke enter the exhaust duct direction, import department arranges guide pipe at exhaust duct, according to exhaust duct specification size, guide pipe, variable-pressure plate has accounted for 10～50% of exhaust duct sectional area, such as patent of invention 00128214.X " structure of pressure-varying air-exhausting duct ", guide pipe, variable-pressure plate has accounted for half of exhaust duct cross section, Chinese invention patent 200510100117.8 " parallel pressure change exhausting duct structure for residential building " has accounted for 20% of exhaust duct cross section, these structures have all been dwindled the draught area of exhaust duct, resistance and the static pressure of exhaust duct inside have indirectly been increased, the lampblack absorber row of wind is reduced, if do not increase the exhaust duct specification, difficulty satisfies the average each household capacity of national standard greater than 300 to 500 cubes of requirements hourly.
Summary of the invention
The utility model stretches into the part of exhaust duct when layer resident family do not discharge fume for fire prevention exhaust in the prior art, can take the area of exhaust duct, resistance and the static pressure of exhaust duct inside have indirectly been increased, the lampblack absorber row of wind is reduced, affected the shortcomings such as exhaust efficiency, provide a kind of when layer resident family not during smoke discharging, the back of the body air deflector of deflector device is in vertical state, parallel with the exhaust duct inwall, can not take the area of exhaust duct; During exhaust, back of the body deflector and exhaust duct inwall form an angle, and form the mozzle structure, can accelerate flue gas and upwards guide the fireproof exhaust passage import transformation guiding device of discharging.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Fireproof exhaust passage import transformation guiding device, comprise the fire-preventing check valve that is arranged on the exhaust duct, also comprise deflector device, and right wing plate and left wing plate, sealing around deflector device, exhaust duct inwall, right wing plate and left wing plate form one, the ventilating duct of up/down perforation.
As preferably, described right wing plate is connected with fire-preventing check valve with left wing plate, and deflector device is hinged by rotating shaft and right wing plate, left wing plate.
As preferably, described deflector device comprises right deflector, left deflector and back of the body deflector, and right deflector and left deflector are hinged with right wing plate, left wing plate respectively by rotating shaft.
As preferably, the height of described rotating shaft is lower than the height of the air inlet port horizontal central line of fire-preventing check valve.
As preferably, the below of described back of the body deflector is provided with balance plate, and the density of balance plate is greater than back of the body deflector.
As preferably, be respectively equipped with sliding mouthful on described right wing plate and the left wing plate, the sliding mouthful of upper bottom baffle of installing.
As preferably, described fire-preventing check valve comprises the valve block of jump ring, plug spring and camber, is provided with the groove that two valve limits with valve body are coupled about valve block.
As preferably, described plug spring is provided with the warming working platform, and the warming alloy is installed on the warming working platform.
As preferably, also be provided with check lock lever on the described plug spring, check lock lever is by the pintle hook lock position locking.
The fire-preventing check valve transformation guiding device that the utility model provides is combined by fire-preventing check valve and transformation guiding device, and the anterior air inlet port of fire-preventing check valve housing wherein place is equipped with a monolithic arc valve block through hinge.The valve casing rear portion is provided with the fire-resistant mechanisms such as warming movement platform and check lock lever.Said transformation guiding device by right three deflectors of the left back of the body with about two wing plate hinges together, and enclose one with fire-preventing check valve.The isoplanar middle and lower part of back of the body deflector is provided with the balance plate that also weighs than back of the body deflector, is fixed with slidably baffle plate between two wing plates bottoms.
During the lampblack absorber off working state, fire-preventing check valve arc valve block hermetically closing is in import department, deflector, wing plate is parallel with fire-preventing check valve is in the exhaust duct, because deflector does not all seal up and down; very thin deflector, wing plate account for the exhaust duct cross-sectional area hardly, effectively reduce the smoke evacuation resistance of bottom work floor.
Lampblack absorber is in working order the time, fire-preventing check valve arc valve block is opened by hinge through, inside flue gas is applied on the back of the body deflector, make back of the body deflector along with hinge inwardly rotates, balance plate outwards rotates simultaneously, until balance plate comes on exhaust duct inwall or the bottom baffle, till can not being rotated further, form the guiding state, bottom flue gas up is applied to again on the balance plate, form support force, the corresponding reaction force that reduces top back of the body deflector helps flue gas along upwards discharging of the mozzle that forms.
When lampblack absorber was closed from duty, fire-preventing check valve arc valve block relied on the gravity rotary closing immediately, under the assistance of exhaust duct inside static pressure, made very tight that the arc valve block closes.Suddenly lacked the large active force of flue gas to back of the body deflector, because balance plate is heavier than back of the body deflector, relied on gravity, back of the body deflector and balance plate progressively return to plumbness along with hinge, and be parallel with exhaust duct, automatically discharges back the exhaust duct draught area.
The utility model is owing to having adopted above technical scheme, have significant technique effect: the utility model is by opening lampblack absorber, push fire-preventing check valve valve block and deflector device open by wind-force pressure, make mozzle rotate into the water conservancy diversion form, be conducive to fume emission; After lampblack absorber was closed, valve block was closed, and the back of the body deflector of deflector device is parallel with exhaust duct, did not account for exhaust duct exhaust gas inside space, had improved greatly the exhaust duct space availability ratio, made fume emission more unobstructed.
