進(jìn)口電動(dòng)低溫調(diào)節(jié)閥
電動(dòng)執(zhí)行器與低溫型調(diào)節(jié)閥閥體組成,內(nèi)含飼服功能,接受統(tǒng)一的4-20mA或1-5V·DC的標(biāo)準(zhǔn)信號(hào),將電流信號(hào)轉(zhuǎn)變成相對應(yīng)的直線位移,自動(dòng)地控制調(diào)節(jié)閥開度,達(dá)到對管道內(nèi)流體的壓力、流量、溫度、液位等工藝參數(shù)的連續(xù)調(diào)節(jié)。電動(dòng)低溫調(diào)節(jié)閥適合于低于0~-250℃狀態(tài)下工作,由電動(dòng)執(zhí)行機(jī)構(gòu)和帶長頸接管的閥體組成,長頸接管的作用是使閥桿密封出接近常溫下工作,并減少外界熱能傳入。為減少傳遞,長頸采用薄壁結(jié)構(gòu)。
Electric actuators with low temperature model of the valve body, with servo function, 4-20 ma, or accept a unified, 1-5 v DC standard signal, convert current signal to the corresponding linear displacement, automatically control the valve opening, to achieve the fluid inside the pipeline pressure, flow, temperature, liquid level and other process parameters of continuous adjustment. Electric temperature regulator is suitable for below 0 ~ 250 ℃ condition, by electric actuators and with a long neck to take over the body, long neck to take over the role of work is to make the stem seal out close to room temperature, and reduce the external heat incoming. In order to reduce transmission, long neck with thin-walled structure.
