Abstract
The utility model relates to an air door of a fan, which belongs to the technical field of the air door of the fan and comprises a rotary handle, a circular front valve body and a circular rear valve body matched with the circular front valve body. Central points of the circular front valve body and the circular rear valve body are connected with each other by a bolt; the rotary handle is connected on the circular front valve body; and a plurality of ventilating grooves which are arranged along the diameter direction are respectively located on the circular front valve body and the circular rear valve body. The air door of the fan realizes the following purposes: the air door has simple structure, is convenient to process and manufacture and requires low cost.
Description
Technical field
The utility model relates to the technical field of air door of fan.
Background technique
Air mass flow when working in order to control blower fan generally adopts air door to control the size of charge flow rate.Be by baffle plate is set on circular disk body at present, control the size of air inflow by the angle between circular disk body and the baffle plate, control accuracy is low, and the curve bath angle is the stroke angle of this air door on the circular disk body.This air door manufacturing and installation cost are lower.
Summary of the invention
The utility model purpose provides a kind of simple in structure, convenient processing and manufacture, air door of fan with low cost.
A kind of air door of fan, it is characterized in that comprising rotating handles, circular front valve shell, with the circular rear valve body that circular front valve shell is complementary, circular front valve shell is connected by bolt with the central point of circular rear valve body, connects rotating handles on the circular front valve shell; Several are set along diametric vent slot on circular front valve shell and the circular rear valve body.
On the circular front valve shell of the present utility model curve bath is set, described curve bath angle is corresponding with diametric vent slot angle, is benchmark with the end of curve bath, with the circular rear valve body that is complementary on wing nut is set.
The utility model adopts technique scheme, and compared with prior art have following advantage: air door of the present utility model does not have barrel, and split is two petal types, and middle with the bolt connection, available plain cushion separates between two blades, reduces interlobate friction.Have the curve bath of certain angle on the front valve shell, and wing nut is set on rear valve body, can be used for adjusting behind the air quantity fixing to blade, rear valve body generally is connected with pipeline or other accessory.The utility model is simple in structure, and convenient processing and manufacture is with low cost.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of air door of fan, comprise rotating handles 1, circular front valve shell 4, with the circular rear valve body 6 that circular front valve shell 4 is complementary, circular front valve shell 4 is connected by bolt 5 with the central point of circular rear valve body 6, connection rotating handles 1 on the circular front valve shell 4; Several are set along diametric vent slot on circular front valve shell 4 and the circular rear valve body 6.
On the circular front valve shell 4 of the present utility model curve bath 2 is set,, described curve bath 2 angles are corresponding with diametric vent slot angle, are benchmark with the end of curve bath 2, with the circular rear valve body 6 that is complementary on wing nut 3 is set.
Air door of the present utility model does not have barrel, and split is two petal types, and middle with the bolt connection, available plain cushion separates between two blades, reduces interlobate friction.Have the curve bath of certain angle on the front valve shell 4, and wing nut is set on rear valve body, can be used for adjusting behind the air quantity fixing to blade, rear valve body generally is connected with pipeline or other accessory.
