With the continuous development of pneumatic butterfly valves, more and more people choose to use pneumatic butterfly valves to achieve the effect of valves. Pneumatic butterfly valves are also used more and more widely. Pneumatic butterfly valves are mainly used in vehicle suspension systems, lifting equipment, damping equipment, and other purposes. The specific situation is analyzed as follows:
1. Pneumatic butterfly valve for other purposes. Using the pneumatic butterfly valve as the shock absorption base can effectively protect precision equipment from damage during transportation, such as the transportation of missiles and control launching devices. The pneumatic butterfly 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 butterfly valve is applied to vibration reduction equipment. The pneumatic butterfly valve has the advantages of high frequency vibration isolation, sound insulation and low natural vibration frequency, which can better realize vibration isolation and ensure the safety and stability of the base of the vibration equipment and the control system. Therefore, pneumatic butterfly valves are widely used in equipment such as vibration isolation of shale shakers and vibration reduction of luxury vehicle seats.
3. Application of pneumatic butterfly 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 butterfly 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 butterfly valves are gradually replacing cylinder products on lifting equipment.
4. Application of pneumatic butterfly valve in vehicle suspension system. The suspension mode with pneumatic butterfly 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 adopted for the vehicle, the automatic adjustment of the vehicle body height can be realized to keep the vehicle body height unchanged, the natural frequency of the pneumatic butterfly valve is low, and the shock absorption and sound insulation 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 butterfly valves on vehicles will become more and more common and broad.
The capsule of the pneumatic butterfly 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 butterfly valve is provided with a height valve, which is arranged in the pneumatic butterfly valve. When the working height of the pneumatic butterfly valve increases or decreases, the pneumatic butterfly valve is provided with a height valve. The height of pneumatic butterfly 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 butterfly 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.
