Abstract
The invention belongs to the technical field of machine design, and provides an exhaust gas recirculation control valve rotating system. The system comprises a control body, a centrifugal shaft, centrifugal cavities, centrifugal bodies, centrifugal springs, arc plates, an elastic band, a rotating shaft, a rotating plate, an exhaust gas recirculation pipe and an arc spring. The centrifugal cavities, the centrifugal bodies, the centrifugal springs, the arc plates and the elastic band are all arranged in the control body. One end of each centrifugal body is arranged in the corresponding centrifugal cavity and connected with the centrifugal shaft through the corresponding centrifugal spring, and the other end of each centrifugal body is of an arc structure and in sealed contact with the corresponding arc plate. The elastic band is arranged on the outer surfaces of the arc plates. When the rotating speed of an engine is high, the rotating plate rotates clockwise, the necking down rate of the exhaust gas recirculation pipe is increased, and the exhaust gas recirculation rate is large; when the rotating speed of the engine is low, the rotating plate rotates anticlockwise, the necking down rate of the exhaust gas recirculation pipe is decreased, and the exhaust gas recirculation rate is small. The system is reasonable in design, simple in structure and suitable for optimization design of an exhaust gas recirculation system.
