Abstract

The invention discloses a low-wind-resistance stepless variable air volume adjusting air valve. The air valve comprises a valve body, a valve plate (16), a valve plate opening device and a flow guiding device. The air valve overcomes the defects that a traditional butterfly valve and a traditional gate valve cannot achieve stepless air volume variable adjustment and local resistance generated in the adjustment process is too large, stepless air volume variable adjustment of all branches of a centralized ventilation system is achieved, local resistance of the air valve is reduced, and the air valve has the characteristics of being capable of achieving stepless air volume adjustment, convenient to adjust the system, stable in working state and the like.
