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

"Jiuzhi 1B14-372 Pneumatic 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, the membrane pneumatic butterfly valve has been widely used on the suspension of domestic and foreign buses. For example, this type of ball valve is used on buses such as Leland, Wuhan WH644 and WH643. The advantages of pneumatic 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, pneumatic butterfly valve is widely used in equipment such as vibration isolation of vibrating screen, vibration reduction of luxury vehicle seats, etc. "Jiuzhi County 1B14-372 Pneumatic Butterfly Valve" pneumatic butterfly valve is also called "air stroke regulator" and "air vibration isolator" according to its performance and point. Two product names. Pneumatic butterfly valve can be divided into three categories according to its shape: bag type, membrane type and sleeve type. Do not use pneumatic butterfly valve beyond the recommended safe extension height. Pneumatic butterfly valves 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 pneumatic butterfly valve and the curved pockets. The large outer diameter is equal to or slightly smaller. After drilling several holes, the flange ring and end plate are used to fasten the connection; The other is the looper flange connection type. The size of the edges at both ends of the pneumatic butterfly valve is much smaller than that of the curved bag. The outer diameter is larger than that of the curved bag. There is no need to drill holes. A flange ring and a common end plate are used for fastening 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.
