Main applications of pneumatic butterfly valve:
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 high-end passenger cars, sedans and tractors abroad, and medium and high-end passenger cars in China are in trial production or preparing to use air suspension systems. When the air suspension system is adopted for 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 butterfly valve is low, and the effect of vibration reduction and sound insulation is good, which can greatly improve the smooth running of the vehicle, the softness and quietness of the seat, and effectively protect the precision instruments and electrical equipment on the vehicle and transport, It can reduce the maintenance frequency and cost, extend the service life of the vehicle, and greatly reduce the impact of the vehicle on the road surface, so as to extend the service life of the road surface. With the maturity of domestic air suspension system application technology and the implementation of the new definition of bus quality level review, the application prospect of pneumatic butterfly valve on vehicles will become more and more common and broad.
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, manufacturing problems, heavy weight, easy leakage and inconvenient maintenance. 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.
Application of pneumatic butterfly valve in vibration reduction equipment
The advantages of high frequency vibration isolation, sound insulation and low natural vibration frequency of pneumatic butterfly valve can better realize vibration isolation and ensure the safety of the base of vibration equipment and 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.
Other uses of pneumatic butterfly valve
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, so as to facilitate the maintenance of field vehicles and equipment.
(1) The cord angle has a greater impact on the vertical stiffness and horizontal stiffness, and also has a greater impact on the strength of the capsule. According to the V-S (volume vertical displacement) diagram in the working process, it is mainly because the different cord angles cause the changes in the volume and effective area of the pneumatic butterfly valve when it is deformed, thus causing the changes in the vertical and horizontal properties, This is not reflected in the empirical formula.
(2) The number of cord layers has little influence on the vertical stiffness, but has a greater influence on the transverse stiffness. Increasing the number of cord layers can obtain a larger transverse stiffness, and can effectively reduce the cord layer,
(3) The higher the internal pressure of the pneumatic butterfly valve, the greater the vertical stiffness, but the internal pressure of the pneumatic butterfly valve has little effect on the lateral stiffness.
(4) The cord density and the distance between cord layers have little effect on the vertical and horizontal stiffness and properties, but have a greater impact on the strength of the capsule., With the increase of cord density and the increase of cord layer distance, the cord layer and large stress value can be effectively reduced.
(5) When the pneumatic butterfly valve is vertically displaced, the volume of the pneumatic butterfly valve changes greatly, resulting in obvious vertical nonlinearity; However, the volume of the pneumatic butterfly valve changes little in the case of transverse displacement, and the transverse performance is linear.
