With the continuous development of pneumatic ball valves, more and more people choose to use pneumatic ball valves to achieve the effect of valves. Pneumatic ball valve is also used more and more widely. Pneumatic ball valve is mainly used in vehicle suspension system, lifting equipment, damping equipment and other purposes. The specific situation is analyzed as follows:
1. Pneumatic ball valve for other purposes. Using pneumatic ball valve as shock absorption base can effectively protect precision equipment from damage during transportation, such as the transportation of missiles and control launching devices. The pneumatic ball valve is used as a support tool, which is light in weight and easy to operate to facilitate the maintenance of field vehicles and equipment.
2. Pneumatic ball valve is applied to vibration damping equipment. 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 of vibration equipment and control system. Therefore, pneumatic ball valves are widely used in equipment such as vibration isolation of shale shakers and vibration reduction of luxury vehicle seats.
3. Application of pneumatic ball valve on lifting equipment. The traditional lifting equipment uses cylinders or hydraulic cylinders to lift objects, which requires large installation space, is difficult to manufacture, weighs heavily, is prone to leakage, and is inconvenient to maintain. After the pneumatic ball valve is used as the lifting element of the lifting equipment, the traditional shortcomings of the lifting equipment can be overcome, the maintenance is unnecessary, the service life is long, and the operation and replacement are convenient. Therefore, pneumatic ball valves are gradually replacing cylinder products on lifting equipment.
4. Application of pneumatic ball valve in vehicle suspension system. The suspension mode with pneumatic ball valve as elastic element is called air suspension system. At present, air suspension systems are almost installed on foreign high-end buses, cars and tractors, while domestic middle and high-end buses are in trial production or preparing to use air suspension systems. When the air suspension system is used in the vehicle, the height of the vehicle body can be automatically adjusted to keep the height of the vehicle body unchanged. The natural frequency of the pneumatic ball valve is low, and the vibration and sound absorption effects are good, which can greatly improve the smooth running of the vehicle, the flexibility and comfort of the seat, and at the same time can effectively protect the precision instruments and electrical equipment on the vehicle and transport, Reduce maintenance times and maintenance costs, extend the service life of vehicles, greatly reduce the impact of vehicles on the road, and extend the service life of the road. With the maturity of the application technology of air suspension system in China and the implementation of the new regulations on bus quality level review, the application prospect of pneumatic ball valve on vehicles will become more and more common and broad.
The capsule of the pneumatic ball valve is assembled into a body by the upper clamping ring and the lower clamping ring, and the upper cover and the piston are clamped. The pneumatic ball valve is provided with a height valve, which is arranged in the pneumatic ball valve. When the working height of the pneumatic ball valve increases or decreases, the pneumatic ball valve is provided with a height valve. The height of pneumatic ball valve can be automatically adjusted through the cooperation of sliding sleeve, pin, rotating arm, valve core and valve body. Since the height valve is integrated with a pneumatic ball valve, the height valve does not need to be adjusted for installation, which is convenient for installation and saves installation space. In addition, the built-in leveling valve is used to reduce the damage probability of the leveling valve, reduce the cost of cab installation, assembly and maintenance, improve the working environment of the leveling valve, and increase its service life.
