Abstract
The utility model relates to a diagonal fan, which comprises an impeller hub and an external case of an impeller, wherein an air inlet duct is formed between the impeller hub and the external case of the impeller, and comprises a slant section and a straight section, the impeller is arranged at the slant section of the air inlet duct, and a flow control device is arranged in the straight section of the air inlet duct; the flow control device adopts a flow control sleeve; and the inclination angle of the slant section of the air inlet duct is 40-50 degrees. The flow control sleeve is installed at the straight section of the air inlet duct, so the diagonal fan has a simple structure, is convenient to operate, is safe and reliable, and can be conveniently operated manually and automatically.
Description
Technical field
The utility model relates to a kind of blower fan technology, especially relates to a kind of convenient diagonal flow fan of regulating flow.
Background technique
From blower fan, flow to the path of outflow by gas, blower fan can be divided into axial flow, radial-flow type and diagonal flow type.The axial fan flow is big, and blast is low; The radial-flow type flow is little, and blast is big.Diagonal flow type is then taken into account axial flow and radial flow type advantage, has the advantages that flow is big, blast is high.But diagonal flow fan is the flow passage structure because of tilting also, is difficult for installing flow regulator.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of diagonal flow fan that can conveniently regulate flow.
The technical scheme in the invention for solving the technical problem is: a kind of diagonal flow fan, comprise impeller hub and impeller outer casing, between impeller hub and impeller outer casing, form air inlet duct, air inlet duct comprises oblique straight section and flat segments, oblique straight section place at air inlet duct is provided with impeller, is provided with flow regulator in the flat segments of described air inlet duct.
In order to make the simple in structure of diagonal flow fan, what described flow regulator adopted is the Flow-rate adjustment sleeve.
Further preferred diagonal flow fan is: the angle of inclination of the oblique straight section of described air inlet duct is 40 °～50 °.
The beneficial effects of the utility model are: the flat segments at air inlet duct is equipped with the Flow-rate adjustment sleeve, and is simple in structure, and easy-to-operat is safe and reliable, manually and all can conveniently realize automatically.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, Flow-rate adjustment sleeve 2, air inlet duct 3, impeller 4, impeller outer casing
5, impeller hub 6, oblique straight section 7, flat segments
Embodiment
A kind of as shown in Figure 1 diagonal flow fan, comprise impeller hub 5 and impeller outer casing 4, between impeller hub 5 and impeller outer casing 4, form air inlet duct 2, air inlet duct 2 comprises oblique straight section 6 and flat segments 7, oblique straight section 6 places at air inlet duct 2 are provided with impeller 3, are provided with flow regulator 1 in the flat segments 7 of described air inlet duct 2; What described flow regulator 1 adopted is the Flow-rate adjustment sleeve; The angle of inclination of the oblique straight section 6 of described air inlet duct 2 is 40 °～50 °.When the Flow-rate adjustment sleeve rotates, air inlet duct 2 is blocked one, the effective admission area of the impeller 3 of diagonal flow fan reduces, and air inlet reduces, and it is installed in flat segments 7 convenient installations of air inlet duct 2, the convenient adjusting.
Claims (3)
1. diagonal flow fan, comprise impeller hub (5) and impeller outer casing (4), between impeller hub (5) and impeller outer casing (4), form air inlet duct (2), air inlet duct (2) comprises oblique straight section (6) and flat segments (7), oblique straight section (6) at air inlet duct (2) locates to be provided with impeller (3), it is characterized in that: be provided with flow regulator (1) in the flat segments (7) of described air inlet duct (2).
2. diagonal flow fan according to claim 1 is characterized in that: what described flow regulator (1) adopted is the Flow-rate adjustment sleeve.
