How to reduce the vibration frequency of electric butterfly valve (electric butterfly valve) device
The electric butterfly valve (electric butterfly valve) is composed of air and has small internal friction, which will not affect the ability to isolate high-frequency vibration due to the inherent vibration of the butterfly valve itself. In addition, the electric butterfly valve (electric butterfly valve) has no metal to metal contact, so it can be soundproof and sound proof. Butterfly valve stiffness: when designing the stiffness of the electric butterfly valve (electric butterfly valve), it can be selected by changing the internal pressure of the butterfly valve, The stiffness is roughly proportional to the internal pressure, so the stiffness can be selected very low as needed. For an electric butterfly valve (electric butterfly valve) with a given size, the stiffness is variable, and it changes with the change of load. Therefore, the natural vibration frequency is almost constant under any load, so it can make the supported system have almost constant performance
The electric butterfly valve is connected to the additional air chamber, but the natural vibration frequency of the electric butterfly valve device is reduced to 0.5 〜 3Hz. Under any load, the electric butterfly valve can maintain a low and nearly equal vibration frequency. An orifice is added between the electric butterfly valve and the additional air chamber. When the spring load vibrates, the air flows through the orifice, causing energy loss, Therefore, it plays a role in vibration attenuation. The fatigue resistance of electric butterfly valve (electric butterfly valve) is many times better than that of metal butterfly valve. For the fatigue test of the butterfly valve in the suspension system of electric butterfly valve in the vehicle, the steel plate butterfly valve only vibrates hundreds of thousands of times and then breaks, while the electric butterfly valve has a vibration amplitude of 40mm The electric butterfly valve is still intact after 5 million times of vibration at a frequency of 2.7 Hz. The body structure of the electric butterfly valve is soft, so it has a comprehensive vibration isolation function in axial, transverse and rotary directions. The electric butterfly valve is relatively inexpensive, easy to install and replace, simple to maintain, and does not need frequent maintenance or refueling. The electric butterfly valve is widely used in commercial cars, buses, rail vehicles Self regulating air suspension for machine equipment and building base

"Jiuzhi 1B14-372 electric butterfly valve" With the development of automobile industry and industrial technology, the use of high-strength nylon, Kaplon and other cord fabrics, in recent years, membrane electric butterfly valve has been widely used on the suspension of domestic and foreign buses. For example, this type of butterfly valve is used on Leland, Wuhan WH644 and WH643 buses. The advantages of electric butterfly valve, such as high frequency vibration isolation, sound insulation and low natural vibration frequency, can better realize vibration isolation and ensure the safety and stability of the base and control system of vibration equipment. Therefore, electric butterfly valve is widely used in equipment such as vibration isolation of vibrating screen and vibration reduction of luxury vehicle seats. "Jiuzhi County 1B14-372 electric butterfly valve" electric butterfly valve is also called as air stroke regulator and air vibration isolator according to its performance and points. The electric butterfly valve can be divided into three categories according to its shape: capsule type, membrane type and sleeve type. Do not use the electric butterfly valve beyond the recommended safe extension height. The electric butterfly valve can be divided into three categories according to the connection mode: one is the fixed flange connection type. The size of the edges at both ends of the electric butterfly valve and the curved pockets. The large outer diameter is equal or slightly smaller. After drilling several holes, use the blue ring and the end plate to fasten the connection; The other is the looper flange connection type. The size of the edges at both ends of the electric butterfly valve is much smaller than that of the large outer diameter of the curved capsule. There is no need to drill holes. Instead, a flange ring and an ordinary end plate are used to fasten the connection The third type is self sealing type, without flange connection, it is pressed into the end plate, and self sealing when filled with compressed air.
