DV6300B隔爆型智能定位器和氣動(dòng)執(zhí)行器配套使用。適用易燃易爆介質(zhì)的場(chǎng)合，通過(guò)接收來(lái)自控制系統(tǒng)的4-20mADC電流信號(hào)得到閥位控制設(shè)定值，同時(shí)采集位置傳感器信號(hào)得到實(shí)際的閥位值，從而控制氣動(dòng)執(zhí)行機(jī)構(gòu)的進(jìn)氣和排氣，驅(qū)動(dòng)閥位到達(dá)調(diào)節(jié)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
產(chǎn)品詳情 Product details
(DV6300B)進(jìn)口隔爆型智能定位器采用微處理器和新型壓電閥代替?zhèn)鹘y(tǒng)定位器中的噴嘴、擋板調(diào)壓系統(tǒng)來(lái)實(shí)現(xiàn)對(duì)輸出壓力的調(diào)節(jié)控制。通過(guò)CPU運(yùn)算處理來(lái)實(shí)現(xiàn)對(duì)閥門開度的輸入信號(hào)和閥位的反饋信號(hào)的控制。壓電閥由于質(zhì)量小，可以釋放很短的控制脈沖，從而達(dá)到很高的定位精度，且壓電閥只有在閥門有偏差并執(zhí)行調(diào)節(jié)動(dòng)作時(shí)才耗氣，所以可以實(shí)現(xiàn)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 utes the adjustment action, so the purpose of low energy consumption can be achieved.
