進口電動低溫調節閥歐美品牌——德國洛克

一、進口電動低溫調節閥描述：

德國LOCKE洛克進口電動低溫調節閥，是由電動執行器與低溫型調節閥閥體組成，內含飼服功能，接受統一的4-20mA或1-5V·DC的標準信號，將電流信號轉變成相對應的直線位移，自動地控制調節閥開度，達到對管道內流體的壓力、流量、溫度、液位等工藝參數的連續調節。電動低溫調節閥適合于低于0～-250℃狀態下工作，由電動執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，長頸采用薄壁結構。

三、進口電動低溫調節閥工作原理：

通過接收工業自動化控制系統的信號（如：420mA）來驅動閥門改變閥芯和閥座之間的截面積大小控制管道介質的流量、溫度、壓力等工藝參數。實現自動化調節功能。電動調節閥執行器內含飼服功能，接受統一的4-20mA或1-5VDC的標準信號，將電流信號轉變成相對應的直線位移，自動地控制調節閥開度，達到對管道內流體的壓力、流量、溫度、液位等工藝參數的連續調節。

進口電動調節閥是一種頂導向單閥座調節閥，具有結構簡單、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.
