R.K.CONTROL閥門定位器VP系列產品介紹
控制器信號（通常為0.2到1 kg/cm的氣動信號）施加到波紋管上。當該信號壓力增加時，波紋管傾向于旋轉杠桿臂。這一運動使得先導繼電器（直接作用式先導）增加定位器的輸出壓力。該輸出壓力反饋到執(zhí)行器，從而推動閥桿。閥桿的運動通過機械聯(lián)動反饋到力平衡彈簧上，導致其加載或卸載，直到杠桿臂上的彈簧張力平衡波紋管的作用力。當這兩種力量平衡時，系統(tǒng)處于平衡狀態(tài)，先導通過控制輸出壓力來維持平衡。

適用于控制閥和動力缸
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.
Features:
Self-relieving
