What do you understand about the bladder pneumatic butterfly valve?
What do you understand about the bladder pneumatic butterfly valve?, Here is a detailed introduction to this issue:
a. The stiffness of the pneumatic butterfly valve is related to the change rate of the effective area of the ball valve dF/dx. Therefore, for the bladder pneumatic butterfly valve with a large change rate of the effective area, the ball valve has a larger stiffness and higher vibration frequency.
b. From the frequency calculation formula of pneumatic butterfly valve, it can be seen that when the volume of pneumatic butterfly valve is larger, its stiffness is lower. Therefore, the stiffness of the pneumatic butterfly valve can be reduced by using the auxiliary air chamber. In the case of high pressure, increasing the volume of the auxiliary air chamber has a more obvious effect on the stiffness. However, this effect will decrease with the increase of volume. Therefore, for the bag type pneumatic butterfly valve, a lower vibration frequency can be obtained by properly selecting the effective area change rate of the ball valve and the volume of the auxiliary air chamber.
c. As the number of curves increases, the deformation can be evenly shared by each curve, so the more the number of curves, the smaller the change rate of effective diameter. It can be seen that increasing the curvature will reduce the stiffness of the pneumatic butterfly valve and reduce the vibration frequency of the ball valve.
