Operating principle of electric butterfly valve
The electric butterfly valve (electric butterfly valve for short) 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 butterfly valve function.
In this way, the electric butterfly valve has ideal elasticity. When the electric butterfly 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 butterfly valve decreases, the volume of the inner chamber decreases, the rigidity of the electric butterfly valve increases, and the effective bearing area of the air column in the inner chamber increases. At this time, the bearing capacity of the electric butterfly valve increases. When the vibration load decreases, the height of the electric butterfly valve increases, the cavity volume increases, the rigidity of the electric butterfly valve decreases, and the effective bearing area of the air column in the cavity decreases. At this time, the bearing capacity of the electric butterfly valve decreases. In this way, the height, inner cavity volume and bearing capacity of the electric butterfly valve in the effective stroke can be smoothly and flexibly transmitted with the increase and decrease of the vibration load, and the amplitude and vibration load can be effectively controlled. The stiffness and bearing capacity of the butterfly valve can also be adjusted by increasing or decreasing the air filling volume. The auxiliary air chamber can also be attached to achieve automatic regulation.
Air leakage analysis and judgment of the air suspension system of Dongfeng electric butterfly valve: as the weather turns cold, a considerable number of air suspension system users report that air leakage of the air suspension should be handled appropriately. The on-board electric butterfly valve suspension system randomly controls and adjusts the chassis height according to the change of vehicle load, which is faster than the previous air 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.
