Abstract
The utility model relates to an air volume regulating device applied to a clack type air volume regulating valve. Inner ring and outer ring of the air volume regulating valve are coaxially fixed and form an air duct; valve clacks are uniformly arranged on the air duct radially with axis of the inner and outer rings as the center; each valve clack is fixed to a hook-shaped valve clack oscillating axle; one end of each hook-shaped valve clack oscillating axle is hinged to the outer ring, while the other end is hinged to the inner ring; hook head of each hook-shaped valve clack oscillating axle is hinged to a round connecting rod with the same angle so that all the valve clacks may be simultaneously opened or closed; the round connecting rod is coaxially hinged in the inner ring; the round connecting rod is provided thereon a rotating handle, to which a positioning locking device is fixed so that the valve clacks may be rotated to a demanded open angle.
Description
Technical field
The utility model relates to a kind of volume adjusting apparatus, is used for lobe formula volume damper.
Technical background
At present, the volume adjusting apparatus of the variable air rate disk return air filter that domestic textile machine enterprise produces, complex structure, processing, assembling, operation all compare difficult, and functional reliability is poor.So that the enterprise that has has cancelled lobe formula control valve, regulate window with air quantity and replace, so both increased manufacturing cost, again useful spaces that taken more.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of volume adjusting apparatus.It can make circumferentially uniform a plurality of flap flexible swinging, pendulum angle height unanimity, and pendulum angle can surpass 90 degree.
The technical scheme in the invention for solving the technical problem is: the inner ring of volume damper and outer ring are coaxial fixing, in, form the air channel between the outer ring, in on the air channel, the axle center, outer ring is the radial uniform flap in center, each flap is fixed with hook-type flap swinging axle respectively, each hook-type flap swinging axle one end and outer ring are hinged, the other end and inner ring are hinged, the gib head of each hook-type flap swinging axle is hinged with angle with circular connecting rod respectively, so that each flap folding simultaneously, circular connecting rod concentric is hinged in the inner ring, on the circular connecting rod turning handle is arranged, stationary positioned locking device on the turning handle is so that can make the opening angle that flap turns over to be needed.
The utility model is simple in structure, flap flexible swinging unanimity, and pendulum angle can surpass 90 degree.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation front view;
Fig. 2 is the utility model structural representation left view;
Fig. 3 is the utility model structural representation vertical view.
The specific embodiment
As shown in drawings, the inner ring 4 of volume damper and outer ring 1 are coaxial fixing, form the air channel 11 of annular between the inside and outside circle 4,1, be the radial uniform flap 3 in center with inside and outside circle 4,1 axle center on the air channel 11, each flap 3 is fixing with hook-type flap swinging axle 2 respectively, and an end and the outer ring 1 of each hook-type flap swinging axle 2 are hinged, and the other end and inner ring 4 are hinged, the gib head 5 of each hook-type flap swinging axle 2 is hinged with angle with circular connecting rod 10 respectively, so that each flap 3 folding simultaneously.Circular connecting rod 10 concentrics are hinged in the inner ring 4, on the circular connecting rod 10 turning handle 7 are arranged, and turning handle 7 is embedded in the fan groove 6 on the inner ring 4 with inner ring 4 concentrics.On the circular connecting rod 10 locking nut 8 is arranged, locking nut 8 can tighten circular connecting rod 10 on inner ring 4, so that can make the opening angle that flap 3 turns over to be needed.Guiding deep bead 9 is arranged between described circular connecting rod 10 and the inner ring 4, play a part to lead and keep out the wind, prevent that circular connecting rod 10 from producing bigger radial displacement in inner ring 4.
Claims (3)
1, a kind of volume adjusting apparatus, the inner ring of volume damper (4) and outer ring (1) are coaxial fixing, in, outer ring (4,1) forms the air channel between, it is characterized in that: in go up air channel (11), outer ring (4,1) axle center is the radial uniform flap in center (3), each flap (3) is fixing with hook-type flap swinging axle (2) respectively, each hook-type flap swinging axle (2) one end and outer ring (1) are hinged, the other end and inner ring (4) are hinged, the gib head (5) of each hook-type flap swinging axle (2) is hinged with angle with circular connecting rod (10) respectively, circular connecting rod (10) concentric is hinged in the inner ring (4), on the circular connecting rod (10) turning handle (7) is arranged, turning handle (7) is gone up the stationary positioned locking device.
2, volume adjusting apparatus according to claim 1, it is characterized in that: described positioning and locking device structure is: turning handle (7) is embedded in the fan groove (6) on the inner ring (4) with inner ring (4) concentric, and locking nut (8) is arranged on the circular connecting rod (10).
3, volume adjusting apparatus according to claim 1 is characterized in that: between described circular connecting rod (10) and the inner ring (4) guiding deep bead (9) is arranged.
