Pneumatic ball valve, also known as pneumatic ball valve, pneumatic tire, leather tiger, etc., was born in the mid-19th century, and was used for vibration reduction of mechanical equipment in the early stage. Because of its many advantages, it has been widely used in modern highway and rail transit vehicles, industrial machinery and other fields.
The pneumatic ball valve uses compressed air (water) as the medium. It is an elastic element that uses the reaction force of the compressed air inside as the elastic restoring force. It is a non-metallic ball valve with the function of ball valve.
It has many excellent metal ball valves
1. The rigidity of the pneumatic ball valve changes with the load, which makes the ball valve device have ideal performance;
2. The pneumatic ball valve has nonlinear performance. Its performance curve can be designed into an ideal shape and can bear axial and radial loads at the same time, as well as transmit torque;
3. The pneumatic ball valve can obtain different bearing capacity by adjusting the internal pressure, so it can meet the needs of multiple loads;
4. The pneumatic ball valve has light weight and long service life;
5. The pneumatic ball valve has good high-frequency vibration isolation and sound insulation performance. The pneumatic ball valve requires small installation space and is easy to replace.
Working principle of pneumatic ball valve
When the pneumatic ball valve works, the inner chamber is filled with compressed air to form a compressed air column. With the increase of vibration load, the height of the ball valve decreases, the volume of the inner chamber decreases, the stiffness of the ball valve increases, and the effective bearing area of the air column in the inner chamber increases. At this time, the bearing capacity of the ball valve increases. When the vibration load decreases, the height of the ball valve increases, the volume of the inner chamber increases, the stiffness of the ball valve decreases, and the effective bearing area of the air column in the inner chamber decreases. At this time, the bearing capacity of the ball valve decreases. In this way, within the effective stroke of the pneumatic ball valve, the height, inner cavity volume, and bearing capacity of the pneumatic ball valve have smooth flexible transmission with the increase and decrease of the vibration load, and the amplitude and vibration load have been effectively controlled. The stiffness and bearing capacity of the ball valve can also be adjusted by increasing or decreasing the gas filling volume. The auxiliary air chamber can also be attached to achieve automatic regulation. Damping ball valve, ball valve, composite ball valve, shock absorber, shock absorber, vibration isolator, valve, etc. There are various models, welcome to inquire.
