Abstract
The utility model relates to a fan, in particular to a fan which is internally provided with an air-quantity adjusting valve function, belonging to the field of ventilation equipment. The fan mainly comprises a shell, a motor, an impeller, a motor frame and an adjusting blade, wherein the motor and the impeller are connected and fixed in the shell by the motor frame; and the adjusting blade is used for adjusting the air quantity. The fan is characterized in that the adjusting blade mainly comprises a blade and a blade shaft; the adjusting blade is arranged in the shell; the shell is not only used as the shell of the fan, but also used as a shell of the air-quantity adjusting valve; the blade is fixed on the blade shaft which is fixed on the shell in a rotatable manner; and the rotation of the blade shaft drives the rotation of the blade, thus realizing the adjustment of effective section area of air flow.
Description
Technical field
The utility model relates to a kind of blower fan, and especially a kind of built-in blower fan of volume damper function belongs to the ventilation equipment field.
Background technique
In the building design of modern society, especially, generally all the subtense angle of ventilation system as building can be used for carrying out between the building inside and the external world air exchange to guarantee the pure and fresh of building inner air as the building of public arena.And generally all can be equipped with blower fan in the middle of the ventilation system, blower fan is used for ambient air pumped in the building or with the air in the building and pumps.Ventilation system generally all the air requirement modulating valve air quantity is regulated, in a ventilation system, volume damper and blower fan are discrete functional units, so often cause the ventilation system occupation space more, and cost are higher.
Summary of the invention
The purpose of this utility model is to provide a kind of blower fan that carries the volume damper function, with volume that reduces ventilation system and the cost that reduces ventilation system.
In order to reach above-mentioned purpose of the present utility model, the utility model is achieved through the following technical solutions: a kind of blower fan with the volume damper function, mainly form by housing, motor, impeller, motor frame and adjusting vane, motor is connected with impeller and is fixed in the housing by the motor frame, adjusting vane is used to regulate air quantity, it is characterized in that: adjusting vane mainly is made up of blade and rachis, adjusting vane is arranged in the housing, and housing is not only as the housing of blower fan but also as the housing of volume damper; Vanes fixed is on rachis, and rachis is fixed on the housing in rotating mode, the rotation of the rotating band moving vane of rachis, thus realization is to the adjusting of the net sectional area of air-flow.
The blower fan of above-mentioned band volume damper function is provided with the driving mechanism of the rachis that connects adjusting vane outside housing, this driving mechanism adopts electric drive mode and/or manpower driving mode.
The blower fan of above-mentioned band volume damper function is provided with the dial of the rachis that connects adjusting vane outside housing, be used to indicate the state of adjusting vane.
The blower fan of above-mentioned band volume damper function is provided with the driving mechanism of the rachis that connects adjusting vane in housing, this driving mechanism adopts electric drive mode.
The utility model is in the inner integrated volume damper function of blower fan, volume damper in the ventilation system and blower fan are united two into one, to reach the purpose that reduces the ventilation system volume and reduce cost, therefore simple in structure and easy realization the utlity model has substantive distinguishing features and remarkable progress.
