Description
Technical field
The present invention relates to a kind of exhaust duct import water conservancy diversion check device, related in particular to a kind of fireproof exhaust passage import water conservancy diversion check device.
Background technology
House exhaust passage check-valves all requires to possess preventing smoke-channeling, automatic fire prevention function, fire resisting damper in the market be to do lower pendulum-type action by valve plate around upper hinge axis to realize valve-off mostly, its shortcoming is that institute's exhaust stream is to form air curtain effect towards tiltedly lower air-out meeting, greatly reduces the exhaust effect of exhaust duct; Small part be valve plate hinge axis location under, the pendulum-type action of doing valve plate realizes the folding of valve, institute's exhaust stream is tiltedly upper air-out, avoid forming air curtain effect, but also exist flip angle to cause not air outlet too small, the shortcoming of exhaust efficiency deficiency, thereby above-mentioned two kinds of inner ventilation areas that all have valve body major part to stay to have taken in exhaust duct a valuable exhaust duct simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of exhaust duct import water conservancy diversion check device, thereby can prevent that air curtain phenomenon, exhaust efficiency are high, improved exhaust duct space availability ratio, make fume emission more unobstructed.
To achieve these goals, the present invention is solved by following technical proposals:
A kind of exhaust duct import water conservancy diversion check device, it comprises valve body, valve plate, wing plate and the air inlet being connected with lampblack absorber, valve plate fixes on the valve body lower portion of hollow by hinges fixing, and described air inlet one end in valve body is inclined-plane and lean face up;
Described wing plate is fixed in the middle of valve plate, and between the plate face place plane of the plate face place plane of wing plate and valve plate, the angle of angle is 30 °-60 °.
Further, on valve body, be provided with positioner, and the position of described positioner is placed with respect to the valve plate back side.
Further, when lampblack absorber is during in off working state, valve plate is due to the existence of wing plate, center of gravity deflection air inlet side, and Action of Gravity Field lower valve plate, taking hinge axis as round dot backswing, is closed in air inlet angle place;
In the time that lampblack absorber is in running order, air-flow promotion valve plate does pendulum-type action around hinge and opens, in the time that valve plate is opened, the windage of valve plate can sharply reduce, and windage is born in now wing plate relay, continuing to promote valve plate rotates, after the back side of valve plate touches positioner, no longer rotate, ensure and have adequate ventilation area, now valve plate becomes guide functions, with on valve body tiltedly part form a passage on tiltedly, impel the air-flow of lampblack absorber to be oblique upper to discharge. Prevent air curtain phenomenon.
In the time that the back side of valve plate touches positioner, the center of gravity of whole check device is still partial to air inlet side a little, in the time that lampblack absorber quits work, under the promotion without wind-force, whole check device relies on the deflection of center of gravity, auto-steering air inlet side, thus close air inlet.
Further, described valve body is fixed on exhaust duct by panel, and the mounting portion of valve body is consistent with the sidewall thickness of exhaust duct. Its effect be no matter lampblack absorber work whether, described diversion check device does not all take the exhaust gas inside space of exhaust duct preciousness, has improved exhaust duct space availability ratio, makes fume emission more unobstructed.
Further, the cross sectional shape of valve plate is "] ".
According to fire-fighting requirement, on hinge, install attemperating unit, in the time exceeding uniform temperature in exhaust duct, the hot melt sheet in attemperating unit disconnects, and the spring on hinge axis discharges valve plate is pressed on to air inlet angle place, valve positive closing.
Beneficial effect of the present invention:
The present invention can prevent that air curtain phenomenon, exhaust efficiency are high, improved exhaust duct space availability ratio, makes fume emission more unobstructed.
Brief description of the drawings
Fig. 1 is that the present invention works as the structural representation of lampblack absorber in the time of off working state;
Fig. 2 is that the present invention works as the structural representation of lampblack absorber when in running order;
Fig. 3 is the structural representation that the present invention is combined with exhaust duct after installing.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing 1,2,3:
A kind of exhaust duct import water conservancy diversion check device, it comprises valve body 1, valve plate 2, wing plate 3 and the air inlet 4 being connected with lampblack absorber, valve plate 2 is fixed on valve body 1 bottom of hollow by hinge 5, and described air inlet 4 one end in valve body 1 is inclined-plane and lean face up;
Described wing plate 3 is fixed in the middle of valve plate 2, and between the plate face place plane of the plate face place plane of wing plate 3 and valve plate 2, the angle of angle is 30 °-60 °.
On valve body 1, be provided with positioner 9, and the position of described positioner 9 is placed with respect to valve plate 2 back sides.
When lampblack absorber is during in off working state, valve plate 2 is due to the existence of wing plate 3, center of gravity deflection air inlet 4 sides, and Action of Gravity Field lower valve plate 2, taking hinge axis as round dot backswing, is closed in air inlet 4 angle places;
In the time that lampblack absorber is in running order, air-flow promotion valve plate 2 does pendulum-type action around hinge 5 and opens, in the time that valve plate 2 is opened, the windage of valve plate 2 can sharply reduce, and windage is born in now wing plate 3 relays, continuing to promote valve plate 2 rotates, after the back side of valve plate 2 touches positioner 9, no longer rotate, ensure and have adequate ventilation area, now valve plate 2 becomes guide functions, with on valve body 1 tiltedly part form a passage on tiltedly, impel the air-flow of lampblack absorber to be oblique upper to discharge.
In the time that the back side of valve plate touches positioner, the center of gravity of whole check device is still partial to air inlet side a little, in the time that lampblack absorber quits work, under the promotion without wind-force, whole check device relies on the deflection of center of gravity, auto-steering air inlet side, thus close air inlet.
Described valve body 1 is fixed on exhaust duct 7 by panel 8, and the mounting portion of valve body 1 is consistent with the sidewall thickness of exhaust duct 7.
The cross sectional shape of valve plate 2 is "] ".
