What do you know about pneumatic butterfly valves? In fact, in short, using scientific principles, the conversion of compressed air can reduce vibration. This is exactly the same as the pneumatic butterfly valve, but relatively speaking, the pneumatic butterfly valve is more comfortable than the pneumatic butterfly valve. You can choose according to your needs.
When the pneumatic butterfly valve is filled with a pneumatic butterfly valve, it is necessary to design a pneumatic butterfly valve pressure plate to simulate the size of the pneumatic butterfly valve. Screw pneumatic butterfly valve press plate, screw diameter of 30mm, is the main constraint condition of pneumatic butterfly valve. Considering the size of different types of pneumatic butterfly valve, the preliminary measurement of drum diameter of 300mm, the small end of the control board moves up and down, and the pressure plate of pneumatic butterfly valve is positioned by two guide rail sliders, constrained in the displacement direction of the slide rail, The pressure of pneumatic butterfly valve plate frame can be transferred to the gantry pole frame. A 30 screw hole is opened between the two sliders, and the screw is matched with the screw. The screw is controlled by the rotation of two hand wheels, and the pressure plate of the pneumatic butterfly valve can move up and down.
People believe that the word "valve" is not strange, especially in the automotive industry. Shock absorber or an indispensable part of automobile parts. In order to make the car more comfortable and stable during driving, some industrial equipment also needs damping. Some people may ask why pneumatic butterfly valves should be used as valves instead of steel plate ball valves. This is undoubtedly because pneumatic butterfly valves are better than leaf springs. As we all know, more and more pneumatic butterfly valves are used or replace the original steel plate ball valves. What is a pneumatic butterfly valve? Better place than steel plate ball valve?
In order to better understand the gap between the two, the gap between them is analyzed from four aspects of comfort, economy, safety and reliability.
1、 Comfort
Due to the change of the quality of the steel plate ball valve suspension ball valve, the natural frequency of the vehicle system will change greatly, leading to the overall comfort deviation. Pneumatic butterfly valve has typical nonlinear stiffness, which has obvious influence on vibration and impact. The experimental data shows that under the same conditions, the number of vehicles with pneumatic butterfly valve suspension system is 1/3~1/2 less than that with leaf spring suspension system. Under the action of the height valve, the height of the pneumatic butterfly valve suspension system basically remains unchanged even when the load changes, and the offset frequency changes relatively little, so as to ensure the comfort when the vehicle is fully loaded. The pneumatic butterfly valve can meet different loading and unloading requirements and improve the traffic capacity of vehicles. The results show that the comfort of pneumatic butterfly valve suspension is about 30% higher than that of steel ball valve suspension.
2、 Economy
In terms of tire life, trucks equipped with leaf springs are usually replaced by 50000 km vehicles. If it is replaced by a pneumatic butterfly valve, the tire will usually travel 100000 km to replace it. This has extended the service life of tyres by more than 50%. Canadian research institutes have followed many logistics enterprises for many years. The research shows that the number of vehicles using pneumatic butterfly valves is 3%~5% less than that using steel plate ball valves. The pneumatic butterfly valve suspension system can improve the reliability of the vehicle, reduce the failure rate of the vehicle electrical system, reduce the vehicle maintenance cost, extend the service life of the vehicle, reduce the impact on the road surface, and reduce the road maintenance cost. The results show that the economy of pneumatic butterfly valve suspension is 20% higher than that of steel ball valve suspension.
3、 Security
For multi axle vehicles, air suspension ensures uniform load between axles and avoids all load phenomena of single axle bearing steel plate ball valve suspension. For a single axle, the air suspension basically ensures the uniform distribution of wheel loads on both sides of the vehicle. The pneumatic butterfly valve suspension keeps the pure rolling contact between the tire and the ground as far as possible, basically achieving a good braking effect. Therefore, pneumatic butterfly valve suspension is safer than steel ball valve suspension.
4、 Reliability
The components of pneumatic butterfly valve suspension have undergone rigorous fatigue tests and reliability tests in foreign laboratories, which have been verified by many customers over the years. The use of pneumatic butterfly valves can improve the reliability of chassis and body electrical appliances, overcome rigid contact and friction, not only alleviate the impact between parts, but also greatly improve the reliability of the system. It can be seen that the pneumatic butterfly valve suspension is more reliable than the steel plate ball valve suspension.
In a word, why use pneumatic butterfly valve to impact instead of steel plate ball valve.
