Description
Technical field:
The utility model relates to a kind of butterfly valve, especially a kind of butterfly valve of the usefulness of ventilating.
Background technique:
At present, the air quantity of middle-size and small-size ventilation duct is regulated the butterfly valve that adopts small-medium size usually, and this butterfly valve is single blade mostly, and blade dimensions is big, and blade rotation is dumb, and surface friction drag is big, regulates control air quantity trouble.
The model utility content:
The utility model provides a kind of butterfly valve of the usefulness of ventilating, and it is simple in structure, and is reasonable in design, and the blade rotation angle is big, rotates flexibly, and surface friction drag is little, and it is convenient to regulate the control air quantity, has solved the problem that exists in the existing technology.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: it comprises the butterfly valve cylindrical shell; A flange is connected respectively at the two ends of butterfly valve cylindrical shell; Middle inside at the butterfly valve cylindrical shell is provided with back shaft in through axle sleeve; In the blade in that is connected on the back shaft, be provided with a side back shaft through axle sleeve respectively on the butterfly valve cylindrical shell of both sides up and down at middle back shaft, be fixed with the lateral lobe sheet that cooperates with middle blade on each side back shaft; Same end at the supported on both sides axle is fixed with a plate respectively, is fixed with one handle in the be connected end of middle back shaft of connecting plate end one side of supported on both sides axle, and the outer end of two connecting plates flexibly connects through a connecting rod, the front end of handle and the flexible connection of connecting rod middle part.
On middle back shaft is connected the axle sleeve of handle one side, be fixed with a positioning plate, the axle center with middle back shaft on positioning plate is that the center of circle is provided with a circular hole, and a location bolt passes circular hole and locatees nut thread with the circular hole and on the handle and be connected.
The utility model is simple in structure, and is reasonable in design, adopts handle to cooperate through the middle blade on back shaft in connecting rod, two common drives of connecting plates and two the side back shafts and two lateral lobe sheets and rotates; The blade rotation angle is big, rotates flexibly, and surface friction drag is little; The air quantity regulation range is big, and it is more convenient to regulate control, and; Blade rotation can be fixed on handle on the positioning plate through setscrew nut behind predetermined angle, makes leaf position fixing reliable.The utility model butterfly valve is suitable for the air quantity of middle-size and small-size ventilation duct to be regulated.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Butterfly valve cross section structure schematic representation when Fig. 2 opens for the utility model blade entirely.
Butterfly valve cross section structure schematic representation when Fig. 3 is the utility model blade complete closure.
Among the figure, 1, the butterfly valve cylindrical shell; 2, flange; 3, middle back shaft; 4, middle blade; 5, side back shaft; 6, lateral lobe sheet; 7, connecting plate; 8, handle; 9, connecting rod; 10, positioning plate; 11, circular hole; 12, setscrew nut.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the utility model is set forth in detail.
Shown in Fig. 1～3; The utility model comprises butterfly valve cylindrical shell 1; The flange 2 that is connected respectively at the two ends of butterfly valve cylindrical shell 1 is provided with back shaft 3 in the middle inside of butterfly valve cylindrical shell 1 through axle sleeve, and blade 4 in is connected on the middle back shaft 3; On the butterfly valve cylindrical shell 1 of middle back shaft both sides about in the of 3, be provided with a side back shaft 5 through axle sleeve respectively, be fixed with the lateral lobe sheet 6 that cooperates with middle blade 4 on each side back shaft 5; Same end at supported on both sides axle 5 is fixed with a plate 7 respectively; Be fixed with one handle 8 in the be connected end of middle back shaft 3 of connecting plate 7 ends one side of supported on both sides axle 5; The outer end of two connecting plates 7 flexibly connects through a connecting rod 9, and the front end of handle 8 and connecting rod 9 middle parts flexibly connect.
, middle back shaft 3 is fixed with a positioning plate 10 on being connected the axle sleeve of handle 8 one sides; On the positioning plate 10 be that the center of circle is provided with a circular hole 11, one location bolts and passes circular hole 11 and locate nut 12 with the circular hole and on the handle 8 and be threaded with the axle center of middle back shaft 3.Operator can come to regulate through handle 8 open angle of butterfly valve intra vane through unclamping and screwed in place nut 12, make the blade location more firmly more reliable.
When the blade of the utility model butterfly valve was opened entirely, as shown in Figure 2, the air quantity that butterfly valve passes through was maximum.When regulating air quantity; Unclamp setscrew nut 12; Clockwise rotate handle 8, cooperate through the middle blade 4 on back shaft 3 in connecting rod 9, two connecting plate 7 common drives the and two the side back shafts 5 and two lateral lobe sheets 6 to clockwise rotate, make vent area and ventilation minimizing in the butterfly valve cylindrical shell 1; When handle 8 clockwise rotates the topmost part, as shown in Figure 3, this moment two lateral lobe sheets 6 with a slice in blade 4 cooperate and make butterfly valve closed, the vent area in the butterfly valve cylindrical shell 1 is zero, wind no longer passes through butterfly valve.
The utility model butterfly valve structure is simple, and is reasonable in design, and the blade rotation angle is big, rotates flexibly, and surface friction drag is little, and the air quantity regulation range is big, and it is convenient to regulate control; And the leaf position after the rotation can be fixed more firmly more reliable through the setscrew nut location.The utility model butterfly valve is suitable for the air quantity of middle-size and small-size ventilation duct to be regulated.
The utility model does not detail part, is those skilled in the art of the present technique's known technology.
