2、风量调节阀技术参数 Air volume regulating valve technical parameters：
2.1、风量调节阀框体和叶片采用镀锌钢板制成，无焊点，表面无需涂装；
Air volume regulating valve frame and blade made by galvanized steel plates, no weld, the surface doesn’t need paint.
2.2、风阀轴承材料为烧结青铜含油轴承，可以耐300℃的高温；
The regulating valve bearing material is sintered bronze oiled bearings, can resist high temperature 300℃;
2.3、叶片由10×10方形轴连接，轴的材料为45#镀锌钢；
Blades are connected by 10×10 square shaft, the material of the bearing is 45# galvanized steel plates
2.4、根据需要可选配可调节风量的执行机构；
We can provide implement facility which can regulating the air volume by need.
2.5、普通型阀体厚度标准尺寸L=210mm，密闭型阀体厚度标准尺寸L=180mm，也可根据客户需要生产各种特型尺寸； The standard thickness of the normal valve dimension is L=210, the standard thickness of the airtight valve dimension is L=180, customers may also choose a variety of special type size;

3、风量调节阀分类以及特点 The air volume regulating valve classification and characteristics：
3.1、分为普通型风量调节阀、密闭型风量调节阀。每种又有对开与平行式两种类型以及手动、气动、电动三种驱动方式；
The air control valve is divided into normal air volume regulating valve、airtight air volume regulating valve. Each of them has two types, Off-style and parallel style, and they have three driven ways: manual, pneumatic, electric, manual;
对开式与平行式选用的一般原则General selection principles of off-style and parallel:
(a)当阀门所需调节的管段阻力大，而阀门消耗的阻力小时宜选用对开式，反之则应选用平行式；
When tube resistance is big but the valve consumes small resistance, it is better to choose off-type on the contrary should choose parallel;
(b)对开式的起始调节性能优于平行式；
The off-type regulation is better than parallel style;
(c)一般做开关用的风阀宜选用平行式；
If the valve used as switch the parallel should be chosen;
(d)当安装在两个系统的混合处时，宜选用相同特性的调节阀，且宜为对开式；
When the valve installed in the mixture place of the two systems, it is better to choose the same characteristics valve, and off-type is better;
(e) 对气流噪声有严格要求的系统宜选配平行式；
There are strict requirements on the aerodynamic noise matching system, parallel way should be selected;
（客户可根据需要选择相应的方式。）
(Customers can select the appropriate way.)
3.2、风量调节阀的特点air volume regulating valve features：
(a)风量调节阀的传动方式为连杆传动；
Drive transmission mode of the air volume regulating valve is the connecting rods way;
(b)普通型调节阀的漏风率不大与2%，密闭型调节阀的漏风率不大与0.5%；
The leakage rate of the normal air volume regulating valve is no less than 2%, the leakage rate of the airtight air volume regulating valve is no less than 0.5%;
(c)手动和电（气）动阀门一般为顺时针方向关闭，逆时针方向开启；
Manual and electric (pneumatic) valve is generally clockwise, counterclockwise open;
