What do you know about electric butterfly valve? In fact, in short, using scientific principles, the conversion of compressed air can reduce vibration. This is exactly the same as the electric butterfly valve, but relatively speaking, the electric butterfly valve is more comfortable than the electric butterfly valve. You can choose according to your needs.
When the electric butterfly valve is filled with an electric butterfly valve, it is necessary to design the pressure plate of the electric butterfly valve to simulate the size of the electric butterfly valve. Screw electric butterfly valve press plate, screw diameter of 30mm, is the main constraint condition of electric butterfly valve. Considering the size of different types of electric 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 electric butterfly valve is positioned by two guide rail sliders, constrained in the displacement direction of the slide rail, The pressure of electric 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 electric 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 electric butterfly valves should be used as valves instead of steel plate butterfly valves. This is undoubtedly because the electric butterfly valve is better than the leaf spring. As we all know, more and more electric butterfly valves are used or replace the original steel plate butterfly valves. What is an electric butterfly valve? Better place than steel plate butterfly 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 butterfly valve suspension butterfly valve, the natural frequency of the vehicle system will change greatly, leading to the overall comfort deviation. Electric 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 electric 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 electric butterfly valve suspension system basically remains the same even when the load changes, and the offset frequency change is relatively small, so as to ensure the comfort when the vehicle is fully loaded. The electric butterfly valve can meet different loading and unloading requirements and improve the traffic capacity of vehicles. The results show that the comfort of electric butterfly valve suspension is about 30% higher than that of steel butterfly 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 an electric butterfly valve, the tire will usually drive 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 electric butterfly valves is 3%~5% less than that using steel plate butterfly valves. Using the electric butterfly valve suspension system can improve the reliability of the vehicle, reduce the failure rate of the vehicle's 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 electric butterfly valve suspension is 20% higher than that of steel butterfly 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 butterfly valve suspension. For a single axle, the air suspension basically ensures the uniform distribution of wheel loads on both sides of the vehicle. The electric 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, the electric butterfly valve suspension is safer than the steel butterfly valve suspension.
4、 Reliability
The components of the electric butterfly valve suspension have undergone rigorous fatigue tests and reliability tests in foreign laboratories, and have been verified by many customers over the years. The use of electric 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 electric butterfly valve suspension is more reliable than the steel plate butterfly valve suspension.
In a word, why use electric butterfly valve instead of steel plate butterfly valve for impact.
