德國(guó)LOCKE洛克進(jìn)口電動(dòng)低溫調(diào)節(jié)閥，是由電動(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(duì)應(yīng)的直線位移，自動(dòng)地控制調(diào)節(jié)閥開度，達(dá)到對(duì)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(zhǎng)頸接管的閥體組成，長(zhǎng)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(zhǎng)頸采用薄壁結(jié)構(gòu)。

三、進(jìn)口電動(dòng)低溫調(diào)節(jié)閥工作原理：

通過接收工業(yè)自動(dòng)化控制系統(tǒng)的信號(hào)（如：420mA）來驅(qū)動(dòng)閥門改變閥芯和閥座之間的截面積大小控制管道介質(zhì)的流量、溫度、壓力等工藝參數(shù)。實(shí)現(xiàn)自動(dòng)化調(diào)節(jié)功能。電動(dòng)調(diào)節(jié)閥執(zhí)行器內(nèi)含飼服功能，接受統(tǒng)一的4-20mA或1-5VDC的標(biāo)準(zhǔn)信號(hào)，將電流信號(hào)轉(zhuǎn)變成相對(duì)應(yīng)的直線位移，自動(dòng)地控制調(diào)節(jié)閥開度，達(dá)到對(duì)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)。

進(jìn)口電動(dòng)調(diào)節(jié)閥是一種頂導(dǎo)向單閥座調(diào)節(jié)閥，具有結(jié)構(gòu)簡(jiǎn)單、密封性能好、流量大、使用可靠等特點(diǎn)。有效而足夠的頂部導(dǎo)向系統(tǒng)克服小開度時(shí)的震動(dòng)，有效使用壽命更長(zhǎng)。

The explosion-proof electric fluorine lined regulating valve imported from Locke lock, Germany, is a low flow resistance through single seat valve, which is suitable for the occasions with strict leakage, low pressure difference between the front and the back of the valve, certain viscosity and fibrous media; the double seat valve has small imbalance force, large allowable pressure difference and large flow capacity, which is suitable for the occasions with less strict leakage requirements; the sleeve valve has good stability and is not easy to produce Vibration, low noise, low temperature sensitivity, suitable for the occasion of large pressure difference and less strict leakage requirements. It is composed of low flow resistance through sleeve valve, pneumatic diaphragm actuator and regulating valve body.
