DV6300B隔爆型智能定位器和气动执行器配套使用。适用易燃易爆介质的场合，通过接收来自控制系统的4-20mADC电流信号得到阀位控制设定值，同时采集位置传感器信号得到实际的阀位值，从而控制气动执行机构的进气和排气，驱动阀位到达调节的目的 DV6300B explosion-proof intelligent locator and pneumatic actuator are used together. Suitable for flammable and explosive media, the valve position control setting value is obtained by receiving a 4-20mADC current signal from the control system, and the actual valve position value is obtained by collecting the position sensor signal, thereby controlling the intake and exhaust of the pneumatic actuator and driving the valve position to achieve the purpose of regulation
产品详情 Product details
(DV6300B)进口隔爆型智能定位器采用微处理器和新型压电阀代替传统定位器中的喷嘴、挡板调压系统来实现对输出压力的调节控制。通过CPU运算处理来实现对阀门开度的输入信号和阀位的反馈信号的控制。压电阀由于质量小，可以释放很短的控制脉冲，从而达到很高的定位精度，且压电阀只有在阀门有偏差并执行调节动作时才耗气，所以可以实现低耗能的目的。Dv6300b flameproof intelligent positioner adopts microprocessor and new piezoelectric valve to replace the pressure regulating system of nozzle and baffle in traditional positioner to realize the regulation and control of output pressure. The input signal of valve opening and the feedback signal of valve position are controlled by CPU operation and processing. Due to its small mass, the piezoelectric valve can release a very short control pulse, so as to achieve high positioning accuracy, and the piezoelectric valve only consumes gas when the valve has deviation and executes the adjustment action, so the purpose of low energy consumption can be achieved.
