Working principle of pneumatic ball valve
Pneumatic ball valve (hereinafter referred to as pneumatic ball valve) is a sealed container filled with compressed gas (the inflation pressure is 0.5-0.7Mpa), and uses the compressibility of the gas to realize its role as a ball valve.
In this way, the pneumatic ball valve has ideal elasticity. 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 pneumatic 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 pneumatic ball valve increases. When the vibration load decreases, the height of the pneumatic ball valve increases, the volume of the inner chamber increases, the stiffness of the pneumatic 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 pneumatic ball valve decreases. In this way, with the increase and decrease of vibration load, the height, cavity volume and bearing capacity of the pneumatic ball valve in the effective stroke have smooth and flexible transmission, and the amplitude and vibration load are 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.
Air leakage analysis and judgment of Dongfeng pneumatic ball valve air suspension system: as the weather turns cold, a considerable number of air suspension system users reflect how to deal with air leakage of air suspension. The on-board pneumatic ball valve suspension system randomly controls and adjusts the chassis height according to the change of vehicle load, which is faster than the previous pneumatic signal. At the same time, it can also directly control the rise and fall of the chassis through the control buttons on the unwheeling operator panel. The un wheeler operator panel is equipped with a control switch through which the un wheeler operator can send electrical signals to the control unit. The control unit sends corresponding signals to the front and rear solenoid valves to inflate or deflate. At the same time, the height sensors fixed at the front and rear bases can also send relevant signals to the control unit according to the load change, and also change the chassis height.
