Abstract
The utility model provides an adjustable amount of wind formula is from hanging down shutter air port. It is in whole frame, connects the combination by adjusting vane, regulating wheel, lock and the tripe that hangs down certainly and forms, and removable guide rails's adjusting vane and regulating wheel mechanism locate oneself to hang down tripe favorable current windward sidewise. Rotate adjusting vane and the fixed adjustable airflow of regulating wheel, the tripe that hangs down is certainly guaranteed that the air current is one -way and is passed through.
Description
Art
This utility model relate to a kind of can mechanical type regulation air quantity one-way gas flow air grille.
Background technology
At present, the existing air grille that certainly hangs down is made up of the BAIYE naturally drooped by deadweight, has control air-flow one-way flow effect.Existing from the air grille air port frequently as smoke proof staircase pressurization air supply system of hanging down.But, due to the existing function not possessing regulation air quantity from the air grille that hangs down, i.e. cannot regulating tuyere discharge coefficient, cause being installed on the air output in same size air port on the smoke proof staircase pressure air blowing each floor of vertical ventilating shaft different, the vertical air quantity of smoke proof staircase and blast are uneven, result reduces the actual safe effect of smoke proof staircase pressurization air supply system, thus cannot meet the requirement of fire-fighting debugging and acceptance test.
Summary of the invention
In order to overcome the existing deficiency that cannot regulate air quantity from the air grille that hangs down, this utility model provides a kind of quantity-adjustable formula from the air grille that hangs down, realize changeable air ports discharge coefficient, so that the air output in same size air port is uniform on each floor of the vertical ventilating shaft of smoke proof staircase.
This utility model solve its technical problem be the technical scheme is that from hang down BAIYE inlet side quantity-adjustable air-valve is being set.Scalable air-valve is made up of the blade of angle adjustable, regulation wheels and wheels lock, rotates regulation wheel thus regulation secured adjusted blade angle.Change the angle of regulation blade, i.e. change the discharge coefficient of air-valve, meet design air flow requirement.Change air port discharge coefficient and regulate the principle of air quantity: air port air output is to be determined by air outlet area, the discharge coefficient in air port and air port static pressure force value.It is different that vertical ventilating shaft prolongs airflow direction borehole wall static pressure everywhere, so in order to ensure that same size air port has identical air output everywhere, then needing to change the resistance (i.e. changing air port discharge coefficient) in air port by regulation blade angle thus ensure that air output is identical.
The beneficial effects of the utility model are, can keep from hanging down while air grille air-flow one-way flow function, can regulating tuyere air output as required.

Detailed description of the invention
In embodiment shown in Fig. 1, in housing, regulation wheel (1) and regulation blade (2) are fixed in regulation blade rotor (3) jointly, and the two rotates with regulation blade rotor (3) simultaneously.Pressing lock (4) and limit regulation wheel (1) rotation, making regulation blade (2) be fixed on needs angle.
Rotate around from the sharf (9) that hangs down under forward airflow function from vertical BAIYE (8), and block inverted draft and pass through；Stopping that adjacent upper level rotates to inverse airflow direction from BAIYE (8) of hanging down from vertical BAIYE rotating shaft (9), catch (6) stops that next stage rotates to inverse airflow direction from BAIYE (8) of hanging down simultaneously.
In figure 3, lock (4) is vertically fixed on lock stator (7), can prolong be perpendicular to lock stator (7) direction stretch and limit regulation wheel (1) rotate.
Claims (2)
1. adjustable air volume formula is from the air grille that hangs down, and by regulation blade, regulation wheel, lock and connects combination from BAIYE of hanging down, it is characterized in that: in overall housing, arranges regulation blade and the regulation wheel mechanism of regulating flow quantity from BAIYE favorable current upwind side of hanging down.
Adjustable air volume formula the most according to claim 1, from the air grille that hangs down, is characterized in that: regulation wheel and regulation blade are fixed on regulation blade rotor jointly, and the two rotates with regulation blade rotor simultaneously；Sequentially the good luck direction of regulation wheel of staggered occlusion rotates and drives regulation blade to change angle；Lock can limit regulation wheel and rotate.
