Describedly determine air quantity valve and comprise valve shaft 18, control valve 5, valve 6, air bag 8 and the baffle plate 9 being installed in housing 1, also comprise the control box 11 that is arranged at housing 1 outside.
Particularly, shown in Fig. 1 and Fig. 2, described valve shaft 18 is in a vertical cross-section of housing 1, and its two ends are pivotally connected to respectively in the two lateral walls of housing 1.Described control valve 5 is a blade, is fixed on valve shaft 18, can be with valve shaft 18 in the interior rotation of housing 1; The sectional area of the area of control valve 5 and housing 1 matches, and by rotating valve door-hinge 18 band movable valves 5, is rotating, and can change the aperture of control valve 5, and then adjust ventilation.Described valve 6 is installed on control valve 5, and its back is connected with air bag 8, and front is positioned at the windward side side of control valve 5, and the through hole in the middle of valve 6 is introduced the air-flow of the windward side of control valve 5 in air bag 8, is air bag 8 inflations.Described baffle plate 9 is fixed on the sidewall of housing 1, and its body stands in housing 1, and offsets at rear and the air bag 8 of air bag 8.
As improvement, described valve 6 can have a plurality of, and described air bag 8 also can have a plurality of, and described a plurality of valves 6 are arranged on control valve 5 the same side with respect to valve shaft 18.As shown in Figure 2, described valve shaft 18 is positioned at the midline of control valve 5,6 upper side positions that are arranged at center line of described valve.
As shown in Figure 1, the lower end of described valve shaft 18 extends in control box 11, and is provided with one section of outrigger shaft 7 connected vertically.Described valve shaft 18 and outrigger shaft 7 can be both integrated, can be also two separate parts.In described control box 11, be provided with a rotating driving shaft 14, on driving shaft 14, be fixed with a cam 13.Described cam 13 has an arcuate flanks, and spring leaf 12 is installed in arcuate flanks.Particularly, one end of spring leaf 12 is fixed in the arcuate flanks of cam 13, and the body resiliency supported of spring leaf 12 is in the arcuate flanks of cam 13, and the other end of spring leaf 12 is connected with the outrigger shaft 7 of described valve shaft by pull bar 10.Further, described spring leaf can be one or more pieces.
Further, the end that described driving shaft 14 extends to outside control box is also fixedly connected with a locating shaft 15, and described locating shaft 15 tightens an intrinsic pointer segment 16, and on control box 11, the position of corresponding pointer segment 16 ends is provided with an arc chute 19; Described driving shaft 14 is socketed with certain position plate 17 in control box, and on described location-plate 17, the position of corresponding circle arc chute 19 is fixed with a double-screw bolt, and this double-screw bolt is inner through arc chute 19 from control box 11, is connected by screw threads for fastening with pointer segment 16.When driving shaft 14 drives locating shaft 15 to rotate, the end of pointer segment 16 can reciprocatingly slide along arc chute 19, by pointer segment 16 is tightened in the end of location-plate 17, pointer segment 16 can be fixed in arc chute 19 relatively, and then the anglec of rotation of driving shaft 14 is fixed.
Further, be also provided with scale on the notch of described arc chute 19, for indicating the anglec of rotation of driving shaft 14, and then the constant ventilation size of air quantity valve is determined in reaction.
Below in conjunction with Fig. 2, the operation principle of the utility model embodiment is described.
When control module is received after opening signal, the air-valve 2 in closed condition is driven by fan valve executor 4 and opens completely, and the air quantity valve of determining that is positioned at rear end enters adjustment state.While entering the air pressure process control valve 5 of housing 1, by valve 6, make air bag 8 inflations, and after air bag 8 inflations, be subject to the barrier effect of baffle plate 9, and then oppositely promote control valve 5.Now, control valve 5 has obtained with the outrigger shaft 7 of valve shaft the active force rotating counterclockwise from air bag 8, and this active force pulls pull bar 10 left and the elastic deformation of spring leaf 12 is increased; Meanwhile, because the elastic deformation of spring leaf 12 increases, spring leaf 12 has also had larger elastic potential energy, and this elastic potential energy is oppositely done work, and pulls pull bar 10 to the right, has produced the active force that the outrigger shaft 7 of valve shaft is turned clockwise.And whole adjustment process is exactly the process of these two rightabout active force dynamic equilibrium.Larger when entering the blast of housing 1, the degrees of expansion of air bag 8 is just higher, the active force that control valve 5 is rotated counterclockwise is just larger, and then can make spring leaf 12 produce larger elastic deformation, and two effect equilibrium of forces make control valve 5 finally be parked in relatively little aperture position.On the contrary, when entering, the blast of housing 1 is less, and the degrees of expansion of air bag 8 is just lower, and the active force that control valve 5 is rotated counterclockwise is also less, only can make spring leaf 12 produce less elastic deformation, two effect equilibrium of forces make control valve 5 finally be parked in relatively large aperture position.By above adjusting, the blast of corresponding different sizes, control valve 5 has the aperture position of different sizes, has guaranteed that the air outlet of unit can outwards be carried relatively constant air quantity.
Further, the relative fixed position by adjusting pointer segment 16 with arc chute 19, can change the initial angle of cam 13, thereby change the initial elastic force of spring leaf 12, thereby changes air quantity setting value.Particularly, described pointer segment 16 is connected in the end of location-plate 17, unclamps the nut of its connection, and pointer segment 16 just can be in the interior slip of arc chute 19; Screw the nut of its connection, pointer segment 16 can be fixed in arc chute 19 relatively, and then the initial opening position of the anglec of rotation of cam 13 and control valve 5 is fixed.
And receive after shutdown signal when control module, fan valve executor 4 is closed the air-valve in open mode 2 completely, and unit will not have wind to be passed through.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
