Double acting pneumatic ball valve Price: Is No. 2 port open or closed? What is the intimate connection between the vertical stiffness and vibration isolation effect of pneumatic butterfly valve in life?
In life, we always connect the vertical stiffness and vibration isolation effect of pneumatic butterfly valves, but what is the connection between them? Please see today's article:
If the vertical stiffness of the pneumatic butterfly valve exceeds the normal range, the vibration isolation effect will be affected; On the contrary, if it is too large (p0 ＞ 0.8MPa), the vertical stiffness of the pneumatic butterfly valve does not drop much, but it puts forward higher requirements for on-site air supply, air tightness, etc., which will lead to waste. Therefore, the initial working pressure of the pneumatic butterfly valve should be selected moderately (0.4MPa ＜ p0 The vertical stiffness of the pneumatic butterfly valve is relatively large, which affects the vibration isolation effect; on the contrary, if the selection is too large (p0 ＞ 0.8MPa), the vertical stiffness of the pneumatic butterfly valve does not drop much, but higher requirements for on-site air supply, air tightness, etc. may result in a certain level of waste. Therefore, the initial working pressure of pneumatic butterfly valve should be selected moderately (0.4MPa ＜ p0 ≤ 0.8MPa); ② For large load (F=107800N) and small load (F=78400N), the initial working pressure should be appropriately larger.
