Ball valve pneumatic butterfly valve is the most commonly used steel shock isolator, which mainly has four types, including disc, spiral, plate and ring. The main advantages of pneumatic butterfly valve are: large static compression, low natural frequency, good low-frequency isolation function; It is resistant to oil, water and other corrosion, and the temperature change does not affect the function; No aging and creep.
Model selection of ball valve and pneumatic butterfly valve: calculate the total working weight of the equipment, that is, the working weight after the sum of the static weight of the equipment and the counterweight multiplied by the safety factor (generally 1.2). The number of pneumatic butterfly valves shall be selected according to the total weight of the equipment. If the total weight is more than one ton, more than 6 pneumatic butterfly valves shall be selected to increase stability. If the equipment is biased, the pneumatic butterfly valve shall be distributed unevenly.
