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. We often use various ball valve pneumatic butterfly valves in industry. Generally, they can be divided into ball valve pneumatic butterfly valve and metal composite pneumatic butterfly valve. The latter has high linearity and heavy weight because its shape is limited by the metal screw ball valve.
Now let's take a look at the structure and application characteristics of the ball valve pneumatic butterfly valve: the structure of the ball valve pneumatic butterfly valve is composed of the metal screw ball valve and the vulcanization wound on it, which generally has a certain ability of elastic deformation. Because the structure is composite, it can have the advantages of both metal and metal.
Features of ball valve pneumatic butterfly valve The ball valve pneumatic butterfly valve is integrated, which overcomes the defects of high rigidity, high operation noise, small ball valve weight, poor shape, and poor mechanical stability. It has a certain coefficient of resistance, so it has a good effect on valves and noise reduction. In addition, its elastic deformation is large, so it has large carrying capacity, stable operation, and short resonance distance. Although the shape of pneumatic butterfly valve is certain. But because of the large elastic deformation. Therefore, it is easy to meet the nonlinear requirements, and the application effect of various parts is better.
In many transportation facilities and the process of aircraft operation, it is inevitable to encounter great resistance force. In order to improve the comfort and riding experience of internal passengers, we must add damping equipment to these mobile machines.
