Pneumatic butterfly valve has strong nonlinear characteristics
The pneumatic butterfly valve has obvious nonlinear characteristics, and its characteristic curve can be designed into the desired shape, such as the S-shaped shape in the vehicle suspension system, that is, the relatively low stiffness in the central part of the curve, and the edge of the tightening stroke gradually increases the stiffness in this way, which can ensure that the driving performance of the vehicle is soft during normal driving, In addition, through occasional places such as corners and forks, the pneumatic butterfly valve has a great deal of experiment and tightening. It gradually hardens, which can limit the amplitude of the body. The characteristic curve of ordinary leaf spring is linear. If this ball valve suspension has the above nonlinear characteristics, it is necessary to make the construction complex.
