How to adjust if the schematic mechanism diagram of high-performance pneumatic butterfly valve cannot be closed properly? After we understand the above information, we can start to select the appropriate pneumatic butterfly valve for the fan.
For high-power and high-frequency fan, it is generally recommended to select ball valve pneumatic butterfly valve or air cushion pneumatic butterfly valve. The advantage of this selection is that it can ensure high vibration isolation efficiency.
When the rotating speed of high-power low-frequency fan is less than 600-700 revolutions, the ball valve pneumatic butterfly valve with deflection greater than 40 mm shall be considered.
For low power high-frequency fan, pneumatic butterfly valve, air cushion pneumatic butterfly valve and ball valve pneumatic butterfly valve can be selected at will.
When small power low-frequency fan is used, air cushion or ball valve pneumatic butterfly valve with large deflection shall be considered.
1. Cast steel shell, alloy steel ball valve, and plastic spray treatment, good weather resistance, effective increase in service life, good shockproof effect.
2. The top and bottom are equipped with anti-skid and wear-resistant fixing bolts, which greatly improves the safety performance and facilitates installation.
3. It can effectively isolate the vibration of various horizontal and vertical water pumps, fans, air conditioning units, generator sets, diesel units, pipelines, and other power equipment, and protect and extend their service life.
