Description
Technical field
This utility model is related to diversion check device and in particular to a kind of diversion check device.
Background technology
House exhaust passage check-valves require that possessing preventing smoke-channeling alters taste, automatic fire prevention function, fire resisting damper in the market
Be to do pendulum-type action by valve plate around hinge axis to realize closing valve mostly, its shortcoming is institute's exhaust stream typically towards oblique
Lower air-out, thus forming air curtain effect, greatly reduces the exhaust effect of exhaust duct；Be partially valve plate hinge axis location under,
Valve plate does the folding that pendulum-type action realizes valve, and institute's exhaust stream is in tiltedly to go up air-out, it is to avoid forms air curtain effect, but there is also
Flip angle not causes air outlet too small, the not enough shortcoming of exhaust efficiency, and above two mostly has valve body major part simultaneously
Stay in exhaust duct thus occupying the inner ventilation area of the exhaust duct of preciousness.
Content of the invention
This utility model, in order to overcome drawbacks described above, its object is to provide a kind of diversion check device.Thus improve
Exhaust duct space availability ratio, makes fume emission more unobstructed.
This utility model to achieve these goals, is addressed by following technical proposals：
A kind of diversion check device, it includes valve body, panel, valve plate, valve rod and air inlet；
Valve body is cylinder, and valve body is coaxial with air inlet, valve rod；
One end of valve rod is connected with the center of valve plate, and support is fixed in coaxial constraint, and it is past that valve rod passes through axial straight line
Valve plate is driven to complete opening and closing movement again.
Described air inlet be tapered, bigger diameter end is coaxially nested in the air inlet inwall of valve body, miner diameter end in valve body, valve plate
Break-make with the clutch for clutch control aerofluxuss of miner diameter end.
The side of valve rod is provided with back-moving spring.
Further, one end of air vent is provided with flase floor, and flase floor is straight at 30.-60.Angle.
Further, support is provided with many radially emanating spokes, is uniformly distributed and is fixed on valve interior wall.
Further, valve plate is spherical arc plate, convex surface facing air inlet.
Further, the one end in valve rod is provided with firebreak device, and firebreak device is made up of spring and hot melt piece.
The beneficial effects of the utility model：
During smoke exhaust ventilator work, air-flow promotes valve plate through air inlet, does axial direction with ovable valve stem in the linear bearing of support
Slide, institute's exhaust stream is along the exhaust passage of valve plate and the diameter difference formation of valve body, then the grid sheet through air vent is in tiltedly above to discharge,
Can effectively suppress to produce air curtain phenomenon.
When smoke exhaust ventilator stops, valve plate is resetted vertically by back-moving spring band ovable valve stem, and valve plate is closed in air inlet, with
Prevent from altering cigarette and alter taste.
When a fire, the hot melt piece of firebreak device is fused by high temperature, and valve plate is pressed in air inlet by the power of release spring
Mouthful.
Described valve body is fixed on exhaust duct by panel, the mounting portion of valve body and flue consistency of thickness, and its effect is
Described diversion check device is not take up the valuable exhaust gas inside space of exhaust duct, improves exhaust duct space availability ratio, makes cigarette
Gas discharge is more unobstructed.
