PROPORTION AIR压力控制器QB1X系列描述及选型
The QB1X is a complete closed loop system consisting of valves, manifold, housing and electronic controls. Pressure is controlled by the use of two solenoid valves. One valve functions as inlet control, the other as exhaust. The pressure output is measured by a pressure transducer internal to the QB1X and provides a feedback signal to the electronic controls. This feedback signal is compared with the command signal input. A difference between the two signals causes one of the solenoid valves to open, allowing flow in or out of the system. Accurate pressure is maintained by controlling these two valves.
QB1X是一个完整的闭环系统，包括阀，歧管，外壳和电子控件。通过使用两个电磁阀控制压力。一个阀用作进气口控制，另一个用作排气口。压力输出由QB1X内部的压力传感器测量，并向电子控制器提供反馈信号。将该反馈信号与命令信号输入进行比较。这两个信号之间的差异导致电磁阀之一打开，从而允许流入或流出系统。通过控制这两个阀可保持准确的压力。
