How to reduce the vibration frequency of pneumatic ball valve (pneumatic ball valve) device
The pneumatic ball valve (pneumatic ball 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 ball valve (pneumatic ball 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 ball valve (pneumatic ball 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 ball valve (pneumatic ball valve) with a given size, the stiffness is variable, and it changes with the load. Therefore, the natural vibration frequency is almost constant under any load, so it can make the supported system have almost constant performance
The pneumatic ball valve is connected to the additional air chamber, but the natural vibration frequency of the pneumatic ball valve device is reduced to 0.5 〜 3Hz. Under any load, the pneumatic ball valve can maintain a low and nearly equal vibration frequency. An orifice is added between the pneumatic ball valve and the additional air chamber. When the spring load vibrates, the air flows through the orifice, causing energy loss, Therefore, it plays the role of vibration attenuation. The fatigue resistance of pneumatic ball valve (pneumatic ball valve) is many times better than that of metal ball valve. For the fatigue test of the ball valve in the vehicle pneumatic ball valve suspension system, the steel plate ball valve only vibrates hundreds of thousands of times and then breaks, while the pneumatic ball valve has a vibration amplitude of 40mm The pneumatic ball valve is still intact after 5 million vibrations at a frequency of 2.7 Hz. The body structure of the pneumatic ball valve is soft, so it has a comprehensive vibration isolation effect in axial, transverse and rotary directions. The pneumatic ball valve is relatively inexpensive, easy to install and replace, simple to maintain, and does not need frequent maintenance or refueling. The pneumatic ball valve is widely used in commercial cars, buses, rail vehicles Self regulating air suspension for machine equipment and building base

"Jiuzhi County 1B14-372 Pneumatic Ball Valve" With the development of automobile industry and industrial technology, the use of high-strength nylon, Kaplon and other cords, in recent years, the membrane pneumatic ball 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 high frequency vibration isolation, sound insulation and low natural vibration frequency of pneumatic ball valve can better realize vibration isolation and ensure the safety and stability of the base and control system of vibration equipment. Therefore, pneumatic ball 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 Ball Valve" pneumatic ball valve is also called "Air Stroke Regulator" and "Air Vibration Isolator" according to its performance and points. There are two product names. Pneumatic ball valves can be divided into three categories according to their shapes: capsule type, membrane type and sleeve type. Do not use pneumatic ball valve beyond the recommended safe extension height. Pneumatic ball valves can be divided into three categories according to the connection mode: one is the fixed flange connection type. The size of both ends of the pneumatic ball valve is the same or slightly smaller, and the large outer diameter is the same. After several holes are drilled, 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 ball valve is much smaller than that of the large outer diameter of the curved capsule. There is no need to drill holes, and 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.
