進口電動低溫調(diào)節(jié)閥優(yōu)選——德國洛克

一、進口電動低溫調(diào)節(jié)閥描述：

德國LOCKE洛克進口電動低溫調(diào)節(jié)閥，是由電動執(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的標準信號，將電流信號轉(zhuǎn)變成相對應的直線位移，自動地控制調(diào)節(jié)閥開度，達到對管道內(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)。電動低溫調(diào)節(jié)閥適合于低于0～-250℃狀態(tài)下工作，由電動執(zhí)行機構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。

二、進口電動低溫調(diào)節(jié)閥主要參數(shù)：  

三、進口電動低溫調(diào)節(jié)閥工作原理：

通過接收工業(yè)自動化控制系統(tǒng)的信號（如：420mA）來驅(qū)動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)。實現(xiàn)自動化調(diào)節(jié)功能。電動調(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的標準信號，將電流信號轉(zhuǎn)變成相對應的直線位移，自動地控制調(diào)節(jié)閥開度，達到對管道內(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)。

進口電動調(diào)節(jié)閥是一種頂導向單閥座調(diào)節(jié)閥，具有結(jié)構簡單、密封性能好、流量大、使用可靠等特點。有效而足夠的頂部導向系統(tǒng)克服小開度時的震動，有效使用壽命更長。

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.
