R.K.CONTROL阀门定位器VP系列产品介绍
控制器信号（通常为0.2到1 kg/cm的气动信号）施加到波纹管上。当该信号压力增加时，波纹管倾向于旋转杠杆臂。这一运动使得先导继电器（直接作用式先导）增加定位器的输出压力。该输出压力反馈到执行器，从而推动阀杆。阀杆的运动通过机械联动反馈到力平衡弹簧上，导致其加载或卸载，直到杠杆臂上的弹簧张力平衡波纹管的作用力。当这两种力量平衡时，系统处于平衡状态，先导通过控制输出压力来维持平衡。

The controller signal (usually 0.2 to 1 kg/cm pneumatic signal) is applied to the bellows. When this signal pressure increases, the bellows tend to rotate the bellcrank lever. This movement causes the pilot relay (direct action pilot) to increase the positioner output pressure. This output pressure fed to the actuator, consequently moves the valve stem. The valve stem motion is fedback through mechanical linkages to the force balance spring, loading or unloading it until the spring tension on the bellcrank lever balances the operating force of the bellow. When these two forces are in balance the system is in equlibrium, with the pilot throtting the output pressure to maintain equilibrium.
