As further improvement of the utility model, described rocking arm sheet comprises supporting portion, the joint of one connection, and described connection part is outside valve block lid body, and joint end face is provided with curve bath, and joint is inclined-plane towards side, supporting portion.
As further improvement of the utility model, it is the conical surface that centre is high, edge is low that described valve block body is formed with pin axle one side surface.
As further improvement of the utility model, described pad is formed with a blocking arm, and described blocking arm end catch is towards any side of rocking arm sheet plane bent.
As further improvement of the utility model, described pad is formed with two blocking arms, and is in line or rectangular-shaped layout between two blocking arms.
As further improvement of the utility model, described pad is formed with three blocking arms, and between three blocking arms, becomes " fourth " shape to arrange.
Technique effect of the present utility model is: the utility model product structure is simply compact, highly versatile; Freely rotated by because of the axis of airflow function in running 360 degree of restriction bypass valve valve block lid body, the relative movement between minimizing pin axle and rocking arm film perforation is worn and torn; The change of valve block lid body diameter does not have a direct impact its anti-rotating function, has stronger versatility to the application of the valve block lid body of different size; Effectively anti-rotating function is integrated on pad, the structural strength of pad is also enhanced.
