R.K.CONTROL放大器VB系列产品介绍
当需要输入隔离或增加流量时，RK容积助推器通常用于以1:1的比例再现气动信号。
助推器具有固定的死区，软阀座结构和整体旁路限制，可消除不具有这些功能的容积助推器可能出现的定位器饱和问题。可调节的整体旁路限制对于系统稳定性是必需的。该调整不会影响音量助推器的死区，但可以使控制阀对较小的输入信号变化做出响应，而不会牺牲稳态精度。
当输入信号发生大而快速的变化时，它还允许升压器提供高输出量，以实现快速冲程。
这些具有固定最小死区的大容量增压器旨在大幅提高大型执行器的行程速度。
只要执行器的信号波动保持在死区限制之内，执行器便会保持其正常的缓慢和稳定响应，该死区限制是通过调节Booster中的均衡/旁通阀来确定的。
RK Volume Boosters are normally used to reproduce pneumatic signals in 1:1 ratio whenever input isolation or increased flow capacity is required.
The booster incorporates fixed deadband, soft seat construction, and an integral bypass restriction to eliminate positioner saturation problems that can occur with volume boosters that do not have these features. Adjustable integral bypass restriction is necessary for system stability. This adjustment does not affect the deadband of the volume booster, but does permit the control valve to respond to small input signal changes without sacrificing steady-state accuracy.
It also allows the booster to deliver high-volume output for fast stroking when large, rapid input signal changes occur.
These high capacity Volume Boosters with fixed minimum dead band are designed to substantially improve the stroking speeds of large actuators.
Actuators retain their normal slow and stable responses as long as their signal fluctuations remain within the dead band limits that are determined by adjustment of the equalizing / by pass valve with in the Booster.
