进口电动低温调节阀欧美品牌——德国洛克

一、进口电动低温调节阀描述：

德国LOCKE洛克进口电动低温调节阀，是由电动执行器与低温型调节阀阀体组成，内含饲服功能，接受统一的4-20mA或1-5V·DC的标准信号，将电流信号转变成相对应的直线位移，自动地控制调节阀开度，达到对管道内流体的压力、流量、温度、液位等工艺参数的连续调节。电动低温调节阀适合于低于0～-250℃状态下工作，由电动执行机构和带长颈接管的阀体组成，长颈接管的作用是使阀杆密封出接近常温下工作，并减少外界热能传入。为减少传递，长颈采用薄壁结构。

三、进口电动低温调节阀工作原理：

通过接收工业自动化控制系统的信号（如：420mA）来驱动阀门改变阀芯和阀座之间的截面积大小控制管道介质的流量、温度、压力等工艺参数。实现自动化调节功能。电动调节阀执行器内含饲服功能，接受统一的4-20mA或1-5VDC的标准信号，将电流信号转变成相对应的直线位移，自动地控制调节阀开度，达到对管道内流体的压力、流量、温度、液位等工艺参数的连续调节。

进口电动调节阀是一种顶导向单阀座调节阀，具有结构简单、密封性能好、流量大、使用可靠等特点。有效而足够的顶部导向系统克服小开度时的震动，有效使用寿命更长。

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.
