Abstract
The utility model discloses a round adjusting damper for a fan. The adjusting damper comprises a cylindrical case, a conical body is arranged at the center of the case, a plurality of petal-shaped air adjusting blades which are distributed radially are arranged between the conical body and the inner wall of the case, one ends of the air adjusting blades are pivoted on the conical body, and the other ends of the air adjusting blades are connected with a U-shaped spindle arranged outside the case, the U-shaped spindle is fixed on the case through a shaft sleeve, the other end of the U-shaped spindle is pivoted on an air adjusting rotary ring arranged outside of the case, and a rotating handle is arranged on the air adjusting rotary ring. According to the adjusting damper, the structure is simple, machined parts are few, the adjusting resistance and noise are small during usage, and the air adjustment is accurate.
Description
Technical field
The utility model relates to the fluid machinery technical field, especially a kind of adjustment doors for regulating fan delivery.
Background technique
Adjustment doors is a kind of fluid machinery that uses with matched with blower commonly used, is used for the adjusting to fan delivery.The petal adjusting vane of the many employings of adjustment doors of the prior art, the drive part of adjustment doors then is comprised of parts such as rotating shaft, interlock handle, rotating shaft cover, rotating disk, pulley, dunnages, rotating shaft in these driving parts, interlock handle, rotating shaft cover, pulley are machine and add part, therefore, raw materials consumption is large during production and processing, and waste a large amount of human and material resources, cost of production is high.In addition, this adjustment doors in use also exists surface friction drag to exist when adjusting vane is operated, and noise is large, and the shortcomings such as idle stroke are arranged.
The model utility content
The technical problem that model utility will solve is: provide a kind of blower fan circular adjustment doors, this blower fan is simple in structure with circular adjustment doors, and it is few that machine adds part, and the adjusting resistance is little in the using process, noise is little, and air quantity is regulated accurately.
The technological scheme that the technical solution problem adopts: the circular adjustment doors of a kind of blower fan, comprise cylindrical shell, be provided with the tap web body at the center of housing, between tap web body and inner walls, be provided with a plurality of petal air quantity adjusting vanes that radially distribute, air quantity adjusting vane one end is articulated in the tap web body, the air quantity adjusting vane the other end is connected with housing U-shaped rotating shaft outward, and the U-shaped rotating shaft is fixed on the housing by axle sleeve, and the other end of U-shaped rotating shaft is articulated in the air quantity adjusting of hull outside and turn-takes.
As improvement of the present utility model: regulate to turn-take being provided with rotatable handle at air quantity.
Beneficial effect: the circular adjustment doors of blower fan of the present utility model, owing to having adopted described blower fan to comprise cylindrical shell with circular adjustment doors, be provided with the tap web body at the center of housing, between tap web body and inner walls, be provided with a plurality of petal air quantity adjusting vanes that radially distribute, air quantity adjusting vane one end is articulated in the tap web body, the air quantity adjusting vane the other end is connected with housing U-shaped rotating shaft outward, the U-shaped rotating shaft is fixed on the housing by axle sleeve, the other end of U-shaped rotating shaft is articulated in the air quantity of hull outside and regulates the technological scheme of turn-taking, by turn-taking U-shaped rotating shaft is rotated and to reach blade standard-sized sheet and full cut-off, realize the adjusting of air quantity, therefore, blower fan of the present utility model is simple in structure with circular adjustment doors, and, it is that machine adds part that the drive part of air quantity adjustment doors only has the U-shaped rotating shaft, reduced the machine dosage, saved manpower, material resources consume, reduced cost of production, in addition, air quantity adjustment doors of the present utility model is owing to adopting U-shaped rotating shaft direct-drive, therefore also have and go slick, degree of regulation is high, no-idle running, the advantages such as the operation friction noise is little; Be provided with the technical characteristics of rotatable handle owing to having adopted to regulate to turn-take at air quantity, further facilitated the manually-operable that air quantity is regulated.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is blower fan of the present utility model with the structural representation of circular adjustment doors.
Embodiment
As shown in Figure 1, the circular adjustment doors of blower fan of the present utility model, comprise cylindrical shell 7, be provided with tap web body 5 at the center of housing, between tap web body and inner walls, be provided with a plurality of petal air quantity adjusting vanes 4 that radially distribute, air quantity adjusting vane one end is articulated in the tap web body, the air quantity adjusting vane the other end is connected with housing U-shaped rotating shaft 1 outward, the U-shaped rotating shaft is fixed on the housing by axle sleeve 2, the other end of U-shaped rotating shaft is articulated in the air quantity adjusting of hull outside and turn-takes 3, regulates to turn-take being provided with rotatable handle 6 at air quantity.
Claims (2)
1. circular adjustment doors of blower fan, comprise cylindrical shell, be provided with the tap web body at the center of housing, between tap web body and inner walls, be provided with a plurality of petal air quantity adjusting vanes that radially distribute, it is characterized in that: air quantity adjusting vane one end is articulated in the tap web body, the air quantity adjusting vane the other end is connected with housing U-shaped rotating shaft outward, and the U-shaped rotating shaft is fixed on the housing by axle sleeve, and the other end of U-shaped rotating shaft is articulated in the air quantity adjusting of hull outside and turn-takes.
