Abstract
The invention discloses a fan air door, which relates to the technical field of fan air doors. The fan air door comprises a rotary handle, a round front valve body, and a round rear valve body matched with the round front valve body, the center points of the round front valve body and the round rear valve body are connected through a bolt, and the round front valve body is connected with the rotary handle; and the round front valve body and the round rear valve body are provided with a plurality of venting channels along the diameter direction. According to the invention, the aims of simple structure, convenience in processing and manufacturing, and low cost are realized.
Description
Technical field
The present invention 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 object of the invention 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 invention 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 present invention adopts technique scheme, compared with prior art has following advantage: air door of the present invention 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 present invention 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 invention.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention 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 invention 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 invention 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.
